Bill,

The Y-BOX v2.1 and single $20 25ft M/F "HD15" cable could let you remote
the KPA1500 or KPA500 to the garage quite nicely, including remote power
power on/off via a K3 macro.  I haven't tested a cable that long, but know
of no reason that it won't work as long as the voltage drop isn't
significant.   Maybe a pair of these high quality cables in series would
work too (50 ft)?

See:

http://www.kkn.net/~n6tv/Y-BOX/Features.html#Remote

and

That last sentence is all too true!

For DXers and contesters, maybe it is time to re-post the following
information from 5-6 years ago.

***************

Many DXers and contesters are still using the factory default AGC
settings, completely unaware that their K3/K3S *could* perform so
much better.

The factory default AGC THReshold for the K3 and K3S is very, very
low. Measurements by KE7X [1] have shown that the default setting of
THR=5 corresponds to an AGC onset at less than S3, while many
competing rigs have a threshold of S7 or even higher. This very low
AGC threshold is what often allows the AGC to be activated by band
noise.

The factory defaults of THR=5 and SLP=12 compress all signals above
the AGC threshold into a very narrow range of audio output levels
[see the measurements by KE7X]. This makes for comfortable
broadcast-style listening - but there is price to be paid: the
default settings greatly reduce the differences in the real-life
strengths of incoming signals. 

These are differences that DXers and contesters *want* and *need* to
hear, in order to pick individual signals out of a pileup.

Following complaints from DXers, DXpeditioners and contesters about
this so-called "pileup mush", and following further series of
measurements by KE7X, Elecraft eventually did increase the available
range of AGC THReshold settings (the v4.51 firmware upgrade, May
2012). 

After the release of FW v4.51, users began to experiment. The
following is a consensus within the [K3-contesting] Yahoo group
about the most important settings for DXing and contesting [2]. 

* AGC THR: increase to at least 8 (from default = 5) and preferably
to 12. Then take some time to become accustomed to the wider range
of audio levels.

Repeat: you may need to give the increased AGC THReshold setting an
extended trial. What you became accustomed to with the factory
setting of THR=5 was an artificially restricted range of audio
signal levels, so a higher THR setting will initially sound quite
'aggressive' - but it is also much closer to real life. 

* AGC SLP: decrease to 8 or even less (from default = 12). Lower SLP
settings allow stronger signals to sound somewhat louder, and thus
more realistic. 

Note: the effects of SLP are partly determined by the THR setting
that you already made (at higher THR levels, SLP has less effect).
So always experiment with THR first, and then adjust SLP as the
second step [1].

* AGC DCY = SOFT (not default=NOR). The User Manual claims that "The
SOFT setting can reduce IMD caused by traditional AGC, and is
especially useful in 'pileup' conditions, in some cases making it
unnecessary to turn AGC off."
 
The changes recommended above have essentially solved the problem of
"pileup mush" for those who have tried them... but regrettably,
Elecraft has done almost nothing to make DXers and contesters aware
that such changes are even *possible*. 
 
It is now 6 years since the v4.51 firmware release notes boasted
that v4.51 "greatly improves signal clarity in pile-ups and other
high-noise or dense-signal situations, especially with threshold set
to 12 or higher". That information is *still* missing from the User
Manual, along with any advice about how to configure the related AGC
settings.

Also the factory AGC defaults remain exactly as they were, optimized
for 'comfortable listening' but far from optimum for DXing and
contesting. One has to wonder how many DX QSOs have been lost as a
result...

[2] The [K3-contesting] group served its purpose and then closed
down.

I thought some here might enjoy some photos from my first SOTA activation
using my brand new Elecraft KX2. This transceiver is absolutely brilliant
for SOTA! Mine has the built in ATU and used the built in Lithium battery
pack. The antenna was a 58' LW held up using a 13.5' fiberglass pole from
sotabeams.co.uk with a 12.8' insultated counterpoise laying on ground.

Everything performed perfectly. The farthes QSO was with K6MW in WA.

The K2 RF board assembly instructions say to install P5 *with the vertical

mean when P5 is installed, the pins are closer to S1 than the locking ramp
is?  Or the other way around?

It depends... 


Some mixes will absorb water then crack when frozen 


You can test one of your toroids by soaking it in water for a day 
then freezing it

There is no need to add additional protection for the K2 toroids.  The 
enamel on the wire provides all the protection that is needed.

Do NOT add any compound to the toroids.  It may cause changes in the 
inductance and render your K2 non-functional.  Besides, it will void the 
warranty.

Mark,

Look at the silkscreen on the board.  The orientation tab on the P5 
header is clearly marked.  The tab mounts closest to S1.  The pins are 
away from S1.

Yeas, but it's a destructive test, like checking the opening current for a
fuse.
I would guess that any core, whether ferrite or powdered iron would be
subject to some water absorbs ion in not coated/painted.

I stopped collecting and exchanging radios after I purchased my K3. 
Hence, this question:

All this talk about AGC settings makes me wonder about the availability 
of similar choices on other rigs. Do other rigs offer this amount of 
customization? Not just in AGC, but all possible adjustments/settings 
that the K3 user can make.

Makes me wonder if any two K3s are set up alike??

Bill,

I have not seen other radios that offer the same level of customization 
as the K3/K3S.
You take the factory defaults and "like it" whether it is optimum for 
your environment and operating desires or not.

I have had several FT-240 #31 cores crack with big chunks out of them or
break in pieces. They were just lying on the ground with several turns of
RG6 through them. They were in rain, snow and ice for a winter here in
upstate NY. These were for receiving. I will be building new chokes and put
them in a 4 x 4 plastic sealed box.

Yeas, but it's a destructive test, like checking the opening current for a
fuse.
I would guess that any core, whether ferrite or powdered iron would be
subject to some water absorbs ion in not coated/painted.

Any choke I construct is in a box, with a 1/64th inch vent hole to keep 
from building a water pump out of my coax.

Kevin,

Yes, the transverters can be used with the KX3.  You will have to bring 
out the Key Out signal from ACC2 (ring contact of the jack).
You will need to set up the transverters for a non-Elecraft Transceiver 
because there is no transverter select information from the AUXBUS 
available as there is in the K2 and K3/K3S.

There are up to 9 transverter bands that can be addressed by the KX3, so 
you can display the output frequency of the transverter.

73,
Don W3FPR

Subject: [Elecraft] Operating Digital Modes via RemoteRig with K3 and local
	PC
Message-ID: <1525374027731-0.post@n2.nabble.com>

Just FYI in case anyone asks about this someday.

I operate 2 remote K3 stations (one at each home) from a K3/0-mini and
RemoteRig units.  At first I tried using a laptop and connecting
audio/serial cables to the K3/0-mini. Eventually I was able to make it work.
Considering the mic and speaker connectors are the same, I used USB mode
instead of data mode.  I found this messy.  

Since I have a PC at each house next to the radio, and already hooked up to
the radio for local operating on digital modes which normally use DataA
mode, this came in handy for remote usage. DataA modes switches from mic to
line in/out.  Setting config to Mic+LineIn and using DataA mode conveniently
lets me use the local PC to run digital modes and view/operate the program
(such as WSJT-X) via a remote desktop connection program but still operate
normally from the K3/0-mini for CW/Voice modes. This also means I can leave
it on to monitor and report signals while away, at least for the station I
last connected to provided I leave the K3/0-mini on, else the remote K3
would be turned off.  I can operate the K3/0-mini volume control and see the
frequency and TX status as normal, but the volume is now independent of the
audio routed to the digital program, so I do not have to listen to the
audio, nor lose audio due to a sound card being plugged in between the
K3/0-mini and a laptop.


The one odd thing I am looking into is when the desktop connection is lost
or minimized for some time, the one home station using a laptop loses its
display and I have to disconnect and reconnect, and the WSJT program stops
hearing audio in.  Simply restarting the WSJT-X (1900 rc3) or going into
WSJT-X setting/Audio and changing audio in setting and saving restores the
audio in the program.  I have yet to see if this is an issue with my other
station which is on a PC.  Both machines are on 24/7 running home automation
and alarm system integration.  I will be digging into this further as the
offending lap[top is in my basement with the transverters and amplifiers and
cabling, rarely ever seen, the K3/0-mini is upstairs. 

I am using the Wi-Fi option at times on my control side RemoteRig, and
recently successfully operated from my RV using campground Wi-Fi in Moab
Utah.  For that I had to connect the RemoteRig via Internet Connection
Sharing on my laptop which provided the connection to the campground
service.  This is because the campground service requires a web log in,
something the RemoteRig does not handle.  I plan to install a Mo-Fi router
in the RV to handle that long term.

I'm moving to the Flex 6600M so my entire station is up for sale.  I'd like to find someone in the Phoenix area if possible but will consider shipping if needed.



K3 - $1875
 P3 Panadapter - $700 
 KPA500 Solid State Amp - $1700
 KAT500 Antenna Tuner - $450 (sale pending)
 Everything runs and works extremely well, I have the full list of all the mods done to the K3 along with all servicing that's been done.  It does not have the 2nd receiver installed.  I have a word file that contains all the updates and will send that out on request. 

If someone buys the entire set up I will include all the interconnecting cables that I purchased from Elecraft:


CBLP3Y         K3S adapter cable for P3 $30
KUSB            USB cable    $40
KPAK3AUX    KPA to K3 Aux Cable    $35
PWR-US240a    US 240V power Cord     $16
E850463        KAT500 to KPA500 cable  $25


All sales will be done through PayPal so add 3% + shipping costs to the NA 48 states only.


If you are a local buyer it will be cash only and pick up so no shipping involved, this would be my number one preference.

I've seen and read a great deal about feeding random lengths of wire, 
usually end fed, in QRP operation. All sorts of tuners and counterpoises 
are proposed and discussed. Question: is the K2 auto tuner sufficient 
and effective in these types of situations? I'm thinking of building and 
installing one, and I'd like to know if the tuner will take care of 
"most" arrangements, or will I still need something outboard. Thanks for 
any and all comments.

Yes. Our ATU algorithm was in fact pioneered on the KAT2. It has eight inductors and eight capacitors, and was designed specifically to match a wide range of random wire antennas. The hardware and firmware were refined over multiple field events.

It?s great. It matches almost anything. In the field I just hook a wire to the end of a fishing pole and throw a counterpoise on the ground. Very quick and easy. I highly recommend it.

OT: For Sale - NOS 36A (30A Cont) Switching Power Supply.  I bought this at a hamfest after seeing the demo that was set up.  A similar unit was powered up supplying 32 amps and had been running for hours.  Seeing is believing.  I was impressed and bought one as a safety or back-up.  It has not been used and is still NIB.


Will take $65 plus $10 shipping & handling to lower 48.  There is no cord; you'll need to make up zip cord with crimp terminals to make it fly.  Comes with instruction sheet & specs.  Can send pictures to anyone seriously interested.


Cheers,

Subject: [Elecraft] 6 meter openings and how to catch them
Message-ID: <53833896-49D4-47A3-9A8D-2E8CB6D6E78B@elecraft.com>

For most of the year 6 meters seems catatonic, at least to those of us with mortal-scale antennas. But then there are times, like right now, where a magic mirror appears in the sky, capriciously reflecting signals all other place. It?s called ?sporadic-E.? 

When the magic is happening, even those with modest antennas, tuned for 6 meters or not, can get in on the fun. What I do is park my K3S or KX3 at 50.125 USB with the squelch turned on, in case someone starts calling CQ above the noise. 

With both rigs, you can turn on ?CW-in-SSB? mode in the CW WGHT menu entry, allowing you to either use SSB or CW as required. (A lot of cross-mode happens on this band since QSB--fading--can come up without warning, leading some ops to switch from SSB to CW to finish a QSO.) 

A great tool that has been mentioned here before is dxmaps.com, which gives you a snapshot of activity on any band of your choice, or all bands, or certain subsets. You can sign up to get alerts emailed to you when a band of interest gets interesting. 

I?ve had multiple alerts each of the past several days -- ?tis the season.

Wayne,

I have a script Perl that scrapes my DX cluster, (will work with any DX 
cluster), then announces when, and what bands are open, via an MP3 file 
played on my home PC, for each band, based on how many spots from zone 3 
are sent from DX stations to the cluster nets...  Works every time on 6 
meter openings...

Another good way is to listen to 50.313 for FT-8 signals.  More of them than
6M beacons in a given area.  Lots of activity there when often there is no
voice (or no voice yet).  Been working the SW states from WWA on and off
much of the day, morning was best so far.

My KX3 has a stuck segment (always on) in about the middle of the S-Meter
display. Power cycle/disconnect isn?t clearing it. Any ideas other than a
firmware reload?
Thanks,

Here is a quick and dirty page with the script in it.

https://www.nk7z.net/cluster-scraper-for-dx-opening/

It is well commented, but remember it is a work in progress, I am in the 
process of switching from Zones, to Grids, as the trigger area, so a lot 
of extra code is in it that appears to not do much...

Have fun.  If you decide to take on the change over to maidenhead grids 
let me know, I'll wait, and just get a copy of your version...  If you 
improve it, please let me have a copy of the improved code...  I will 
add a CC release to this version later this week.  Our local club 
meeting is this evening in about an hour, so I need to run...

It is NOT plug and play, you will need to look at the subroutine named 
"cluster login", and change to your favorite cluster.  There are a lot 
of directory dependent things in it as well...

It will not take any more resources that a spotting program, while 
connected to a cluster, but it will auto log back in forever, so you may 
want to break that feature before you use it.

It also has my local IP address for my machine that runs the cluster. 
Feel free to use:

nk7z-cluster.ddns.net:7373

as the cluster to test with...  That is also a freely available cluster 
for anyone to use...  It is a reasonably well connected cluster...

Everything is globally declared, so there is a lot of space saving that 
could happen... I want to get it running before I dress it up...

73s and thanks,
Dave

Bingo!
It was at -20. It?s usually something simple or overlooked. Thanks Michael.

If you don't recall having changed RF Gain recently, I'll note the default value in my rig control software (FLRig) did this to me when I first installed it.

I?m the culprit. Running FT8, I had AGC off and rode the RF Gain but I don?t recall this happening previously.

While the Elecraft antenna tuners are excellent and wide range, don't be
surprised if you find wire lengths of antenna and counterpoise that they
will not get a match on for a given band. You may still find you have to
fine tune the lengths for them to work on all of your favorite bands, even
if you have used one of the widely recommended lengths to avoid half wave
end fed operation.  Results can also be strongly affected by how the wire
is deployed. At least that has been my experience with K2/KAT2 and
KX3/KXAT3, and KX2/KXAT2. But then, that is part of being a ham -
experimenting a bit to get your best results.

Subject: [Elecraft] Question on KX3 transmit errors
Message-ID: <CAEhYShK+oOoLWzBaj-tyD71MRP04Y3wRNtPP-RjKJXYdw1h-sQ@mail.gmail.com>

Hi folks,

I am new to Elecraft.  I received my KX3 kit and built it yesterday.  Was
very careful to follow all the directions and warnings.  Now completed, the
receiver seems to work great, but having trouble with transmit.

In any mode, any band, any PTT request (key, mic PTT, etc), I instantly get
four errors:  TXS  TXN  TXO and TXR.

I have enabled the tuner in the menu, but if I hit the tuning button, it
says no tuner (while in the menu, flipping through all the L and C combos,
I hear the ATU relays clicking).

Suspecting the tuner, I removed it, turned it off in the menu and plugged
the BNC directly into the RF board.  I still get the same 4 errors.

I saved my settings and did an EEINIT.  Didn't help.

I've written to Elecraft support and suspect I'll hear back next week, but
I thought I'd ask here in case anyone had any pointers for me on what I
might check while I was around this weekend.

Many thanks.

James,

Those errors and an explanation are in the chart near the end of the 
manual.  Those refer to attempting to transmit before doing several of 
the calibration procedures.
The boards should have been pre-calibrated at the factory, but if yours 
was pre-calibrated, the data has somehow disappeared.

You can try doing those calibration procedures to see if it helps.

Hi to all .. I have a problem with my KX2 which appeared today. When I 
press ATU to start a tuning sequence, I hear the familiar relays noise 
of the KXAT2. the 3 W power level is indicated, but it seems that no 
power is getting out to the antenna or dummy load. After 2 or 3 seconds, 
the sequence stops and a 25:1 SWR is indicated ... ...

Any suggestion?

Thanks de Pierre VE2PID KX2 s/n 1464

This often indicates the connection between the ATU and the BNC has opened.

... I forgot to say that I can transmit and make QSOs with the rig even 
with these high SWR so the power is getting to the antenna. The problem 
(no power out) is present only during the tuning sequences.

Subject: [Elecraft] K2 VFO encoder / control board close fit
Message-ID: <CABMnSbFk+wyOYA=mRZUXNbF5R4nGktN1pGytEU8VE1hDk+2duw@mail.gmail.com>

While performing the initial power on tests on my K2 S/N 7809, I noticed
that the VFO knob/display tuning test produced a sluggish, intermittent, or
no change in display when I turned the knob in either direction.

I proceeded to remove the two chassis screws securing the control board to
the front panel board.  This allowed the control board to relax and
slightly fall away from the front panel board, toward the back of the
radio, opening up the space between the front panel encoder board and the
control board. The display was at once responsive to knob turning on all
RATE settings.

Next, I slipped a piece of paper between the encoder board and the control
board, then reattached the control board to the front panel board with the
chassis screws.  The display continued to be properly responsive to knob
movement.  When I tugged on the paper to see how tight the fit was, it
resisted being slipped from its position.  It was fairly pinned down.

Here is a photo of the control board backside taken at a glancing angle,
showing the joints for J1 in the foreground, and the pins of the U6 socket
behind that.  The socket pins should probably be trimmed, which I did not
anticipate.  The other joints, while not necessarily overly beautiful, I'll
also check for height.  It's not clear to me which pins on the encoder
board are shorting to which pins on the control board, but it seems clear
that some are.

https://photos.app.goo.gl/KDzlAixNghg2tmhy1

If after trimming the U6 socket pins the problem persists, I'll leave the
paper slip in, but I don't feel great about it.  The paper could fail on
these sharp solder joints given vibration over long periods of time.

Has anyone else had an experience like this where the front panel board
meets the control board?  I believe the manual talks warns about this
condition.

Thank you.

Mark...

All else aside, I'd suggest using good quality electrical tape, perhaps 
even two layers. It won't slip and has a better half life than paper.

This may have been discussed already, but just wanted to confirm.

I had a number of questions, but I'll condense them into a few:  

How are the KPA-1500 power LEDs/display calibrated at the factory, and what equipment is used to do the calibration?

Second, in the case of using the amp with K3 and the KPAK3AUX cable, is there a point where ALC kicks in and decreases power output?

Thank you!

Mark,

The instructions packed in the encoder envelope tell you to flush cut 
not only the pins on the encoder board, but also the leads on the 
control board that might contact it.

If you do not have flush (or shear) cutters, and want inexpensive ones, 
look for Xcelite (or Lufkin or Cooper) 170M shear cutters.  They can 
often be found in your local Home Depot.

In addition to flush cutting the boards, put something on the back of 
the encoder board - fish paper would be best, but a piece of flat 
plastic cut from one of the many plastic wrapped consumer products would 
be good.
Paper or electrical tape will eventually puncture.

Don W3FPR

You're kidding of course -- 46C = 118F, which is a typical summer's day in 
the central valley in Calif. So sitting at a picnic table in the shade of a 
tree, with the K3 turned OFF is what the PA temp would be! That's super 
cool!

I've been perusing the manual for my KX2 and am wondering what others may
be using the AUX capability for (for those who have that option installed)?

The manual mentions an antenna switch being one possibility and, more
intriguing, that Elecraft may at some point offer accessories that make use
of these contacts.

Anyone using this feature now...and for what?

One of the very popular serial communications programs available in the Apple Mac store is an application called ?Serial?.  What makes this app nice to use is that it includes built-in driver interfaces for just about any USB-Serial or serial interface you could put on a Mac computer.

I decided to connect to my K3 using Serial.  But, I am having trouble getting the K3 to respond.  I know I have the right comm port and I know that the K3 can communicate over this comm port.  

Has anyone used Serial (the app from company Decisive Tactics, Inc.) to communicate with a K3 or any other Elecraft equipment?

 I am not sure what you're planning to do with "Serial" but when I'm using my K3/KIO3B withWSJT-X, I have the program configured for CAT Control on /dev/cu.usbserial-A5xxxxx at aBaud rate of 38400, 8 data bits, 1 stop bit, Handshake set to 'None', and PTT Method of RTS(set to the same /dev/cu.usbserial device), Mode Data/Pkt, Split 'Rig', and a 1 second Poll Interval.CONFIG:KIO3B is set to 'nor'.
Permissions for the port device file are set to 666 and owner/group is root/wheel.
You might also want to double-check About My Mac -> System Report -> Hardware -> USBto see if the K3 is showing up - mine is a 'General Purpose USB Hub' with a TI vendor IDwhich has a USB Audio Codec (Burr-Brown) and an FT232R USB UART whose serial numbermatches the device special file that WSJT-X is talking to.
Also, go to System Preferences -> Network and make sure that that port is not configured.(It most likely is not, but Murphy does very strange things at times!)
It wouldn't surprise me if Serial might have a permission problem/setting that's fouling you up,but that's just a SWAG on my part. I'm running Lady Heather through another USB line to myGPSDO without any fiddling on the macOS side, but you never know.

I just finished writing a python program to make it easier to control 
the K3 internal EQs.  The impetus is to easily adjust in response to 
on-air reports, or to adjust when using MON to listen to myself in 
headphones.

One of the things I've done is to include a file of presets drawing from 
recommendations of knowledgeable hams.  An example is shown at:

    http://udel.edu/~mm/ham/elecraft/python/

Are there are other recommendations from anyone?  I'm especially looking 
for recommendations coming from those with substantial audio background. 
  The idea is for us audio neophytes to steal, er, learn from the learned!

I'm restoring a Heathkit line of DX-60B xmtr, HR-10G vfo, and HR10 rcvr. 
  The DX-60B is cw or am, so I've become interested in AM settings of 
late.  :-)

I'm moving to the Flex 6600M so my entire station is up for sale.  I'd like to find someone in the Phoenix or surrounding area if possible but will consider shipping if needed.

K3 - $1875
P3 Panadapter - $700 
KPA500 Solid State Amp - $1700
KAT500 Antenna Tuner - $450 (sale pending)
Everything runs and works extremely well, I have the full list of all the mods done to the K3 along with all servicing that's been done. It does not have the 2nd receiver installed.  I have a word file that contains all the updates and will send that out on request. 
If someone buys the entire set up I will include all the interconnecting cables that I purchased from Elecraft:

CBLP3Y        K3S adapter cable for P3 $30
KUSB           USB cable    $40
KPAK3AUX    KPA to K3 Aux Cable    $35
PWR-US240a    US 240V power Cord     $16
E850463        KAT500 to KPA500 cable  $25

All sales will be done through PayPal so add 3% + shipping costs to the NA 48 states only.

If you are a local buyer it will be cash only and pick up so no shipping involved, this would be my number one preference.

Brandy,

Actually, I wasn?t planning to do anything with the Serial app and comms to the K3.  My questions stem from the fact that I have used Serial with a number of other devices (mostly Arduino, Raspberry Pi, and PIC boards)  so I thought: try it out with the K3.  My failure to get a response is what prompted my question.

Not sure I will find anything amiss from your suggestions (already having done one or two of those types of checks) but I will try again.  Now, it is a mere curiosity thing ? this should work.  I have successfully communicated with Elecraft serial equipment using my own serial-comms programs I have written (C and Python).  Ordinarily of course, I use only the Elecraft utilities to do anything useful.

73, phil, K7PEH

The Wizkers program also does this, along with other things.

I collected TX EQ settings from posts to this mailing list and wrote that up a couple of years ago. The blog post is here. The title says ?KX3?, but it is the same for the K3. Or any radio, really, because this is about voice, not the rig.

I got mine from Jim, K9YC, a retired audio professional designer and 
consultant in large venues.? They are:

1 -14
2 -10
3 -6
4 -2
5 0
6 +4
7 +6
8 +10

I don't frequent phone much but when I do [like in an NAQP SSB or SS], I 
usually get one or two "great audio" comments.? While most of that is 
undoubtedly due to superior DNA, I think the K3 TX EQ has something to 
do with it. [:-)? Close-talking some mics tends to boost the lows too, 
sometimes significantly.

Jim points out that there is no value to power in the low frequencies, 
they carry almost no information.? Watching the P3 waterfall with a 
narrow span demonstrates dramatically how many SSB signals have all the 
power in the lows, crammed up against the suppressed carrier, and next 
to nothing out where it would be beneficial.

Mike I had the very same thing happen last night while operating the 7QP
contest..... which is the first contest I have operated with the KPA1500
.... the heatsink temperature was down in the mid 40s C at the time .... and
in my case it occurred on 160 meters only .... SWR as per other meters as
well as the digital readout on the 1500 were reading 1.2:1 ... and did not
change even when the LED flashing occurred ..... but I was getting
intermittent flashing of all LEDs on the amp's SWR meter ....

During the contest I was continuously running on CW with hourly QSO rates
running between the 70s and 110s .... I opted to manually switch on the fan
to keep the temperature below 60 degs C ..... level 2 seemed to keep it
there most of the time .... but I did move up to level 3 a few times  (and
BTW, at that speed the KPA1500 is clearly the noisiest amp I have ever owned
.... but, arguably, it may very well be the "coolest" also ..... headphones
were absolutely necessary with that noisy fan ..... clearly much noisier
than the Alpha 9500 sitting right next door ... which I also used during the
same contest...

So Mike, you're not the only one experiencing this phenomenon.... whatever
it is..

Don, N5LZ   (KPA1500 #45)

I have noticed that after my KPA1500 gets above 50C the SWR indicator light
starts to show intermittent high SWR. My KPA500 did not do that. I'm using
resonant yagis and the digital SWR meter shows 1.1:1 and doesn't change nor
does the SWR indicator on the K3S. It seems the SWR indicator lights are
acting independent of the meter on the KPA1500 screen. RF? I have not had
any faults or shut downs as a result of the indicated high SWR. The amp
operates wonderfully, but the indicator lights are a bit bothersome. Anyone
have similar issues?

I?m using VE3NEA?s Faros NCDXF beacon software to monitor the 5 bands using
my K3S on bypass with a KAT500 on bypass, as my two antennas have rATUs at
the bases. When I set the KAT500 to ANT2 it keeps switching back to ANT1 so
I figure it must be remembering a prior band/ANT setting. How do I make it
use just ANT2 for all 5 bands?

Congrats on the DNA, Skip.  :-)  And thanks for the EQ info.  With info 
sent to me off-list by a few as well on your info on-list, I see 
variations by Jim k9yc and Bob Heil k9eid, likely due I assume to 
different mics & on-air advice for different op voices - unique for each 
environment.

Tnx es 73,

How many of the beacons are running now?  I stopped using FAROS because 
the beacons started going away...

I have a loop under test right now using WSPR, and my K3, at 2 watts... 
It will be up for the next 24 hours.

I have the same problem with S/N 64.  I thought it might be a cable but the
problem occurs on all bands, both antenna outputs and into a dummy load.
I'm only about 90% sure that it is related to temperature - I was too busy
working the contest to do much more troubleshooting.  And I agree with the
fan noise comments - the pitch of the noise comes right through my Bose
noise canceling headphones.

Hopefully Elecraft can duplicate the apparent temperature related SWR
problem and resolve it.

The loud fan noise contradicts preliminary reviews. Perhaps the early
testers did not run the amp in a contest environment where it heated up.
There are over 125 KPA1500's that have been manufactured so they should be
getting used in all types of environments now. I hope to order one for my
station, eventually.

You can easily assign antenna ports using the KAT500 utility and a 3.5mm
to USB cable.

Just to clarify as far as the KPA1500 fan noise is concerned and my experience with s/n 45.  In auto mode the fan kicks on when the heatsink temperature reaches 60 degs C ?. I first noted that while I was vigorously chasing a DX station in a split CW pileup.   It kicks on at 60 degrees and switches back off when the temp goes down ?. So, in auto mode, it can be rather distracting when it?s right at that threshold and frequently switching back and forth ?.. so, in that situation, I have been opting to turn the fan on manually.   There are five selectable fan speeds ?. 1 through 5 ? speeds 1 and 2 are no big deal as far as noise is concerned ?. Just like any other amp ? the noise is there but it?s not excessive ? when you hit speed 3 the pitch goes up and the noise goes up ?. And 4 and 5 are progressively more intense ? in both pitch and noise level.   I have never found it necessary to go to levels 4 or 5? but I?m primarily operating CW only ?. No full keydown rtty or AM at my station ?.  I have needed level 3 to keep the heatsink temp below 60 degs C while continuously CQing in a contest run mode however?. And with all the associated noise good earphones are an absolute must.  It really does not take long to cool things down when the fans are running at level 3 ?. The fans work ?. And they do the job they?re supposed to do.

There?s no free lunch ?. If you?re going to use an amp it?s going to get hot ? the more you transmit the hotter it will get ? and you need to keep it as cool as possible.  I have no problem with the high noise levels necessary when things get really hot.  I just keep my earphones handy.

Yes, this is true

For all these LMDOS amps, you need to dissipate all that heat and the
common way is with a Fan, so you really have no choice but to get used to
it.  You have to move a defined amount of air to do the cooling.  Small
fans need to spin faster to move more air than larger fans spinning
slower.  The more compact the amp is the more air you have to move and it
can be noisy.

Move it further away, invest in headphones, etc.   If it is noisy, maybe
drop down 3db to 1/2 power and 1/2 the heat generation.   Put the amp in
another room if you can.

Like Don said, there is no free lunch.  You can't have big time
amplification without producing heat.

It is all in the math.

Not quite what I recommend.? My "starting point for typical ham mics 
like the Yamaha CM500 headset is:

Bands 1, 2, and 3:? Maximum cut (-18)
Band 4:? -6
Bands 5, 6: 0
Band 7: +6
Band 8 +6

Set Mic Gain and CMP for indicated Gain Reduction of 10 dB on peaks.

Then, get signal reports from trained listeners who have their IF 
bandwidth set for 2.7-2.8 kHz.? These are settings for maximum audio 
"punch" to get through QRM and noise. They get rid of un-needed bass 
which makes no contribution to speech intelligibility and boosts highs a 
bit because they DO contribute a lot. Ignore reports that tell you that 
you lack bass -- you don't want it, because it wastes TX power.

These settings increase the effective voice power by about 13 dB 
(multiplying power by 20).

Since I'm primarily a contester, DXer, and weak signal VHF op, nearly 
all my operation is with headphones. The exceptions are WSJT modes, 
where I mostly use the speaker, turned down, and MSK144 on 6M, where I'm 
listening for pings. With the KPA500 on a shelf just above the rig, I've 
done what others suggest -- set the "normal" fan speed a few steps 
higher to increase the time before the fan kicks into "high" after a lot 
of long TX cycles.

I'll do something similar with the KPA1500 when I get around to buying it.

Question, were these the original setting suggestions from Jim or are these
the "final" settings after personal adjustments?

Several experienced ops gave similar recommendations for TX EQ. These
settings are from Jim Brown (K9YC) and I used them without any change.



Freq. Band   50Hz 100Hz            200Hz            400Hz
800Hz
1600Hz         2400Hz             3200Hz

EQ       -16dB             -16dB             -16dB             -3dB
0
0          0          +3dB



The 3.2kHz boost is optional, use it if it works for you. I did not.





I got mine from Jim, K9YC, a retired audio professional designer and
consultant in large venues.? They are:



1 -14

2 -10

3 -6

4 -2

5 0

6 +4

7 +6

8 +10





Using this config file:



    SSB|-16|-16|-16| -6|  0|  3|  5|  6|Brown, Jim K9YC

I followed Jim's EQ recommendation which he as stated a number of times on
this list. For clarity I posted it here: 
http://mailman.qth.net/pipermail/elecraft/2017-April/244127.html I believe
that this is an excellent recommendation. I received a number of
unsolicited "great audio" reports while operating as PJ4R in March WPX.

my voice, mic [Heil iC electret in a ProSet], and room acoustic 
characteristics, based on tests with several local-ish friends ... one 
of whom may have been Jim, memory fails here.? Should have been more

I put the K3 on the DL, disconnected the P3, and tuned it to my TX QRG.? 
The settings I posted cause my voice, mic, and room characteristics to 
pretty much fill the SSB passband.

I did a lot of A-B testing on my K3s TX EQ settings, using Jim's base settings vs flat EQ, high base, flat mid/treb, et al. settings in various conditions on multiple bands.
Mostly for fun, because the science is well established...
Yes, I got more "you sound good, full, et al." with flat or boosted bass from stations that could copy on both settings...
BUT, I was able to demonstrate conclusively that more stations in "fringe" reception conditions copied when using full cut base, flat mid, and boosted highs.? I actually mapped it out.
Now I use a customized version of Jim's base rec that fits MY specific mic best.? (I don't need to boost the highs as much).
Win4K3 Suite allows me to store different settings based on purpose...

Can someone point me to the correct direction to get my K3 setup?

 

Also, I understand I need a way to keep better time for my K3. What's the
recommended software to do that?

 

Tnx for any feedback

Announcing W6SFM'sBUG ROUNDUP <https://w6sfm.com/bug-roundup/>

The Samuel F. Morse Amateur Radio Club, a Sacramento, California based 
CW enthusiast club wanted a special time to bring bug operators together 
on the air. In the same spirit as ARRL's Straight Key Night, 
participants are encouraged to make simple, conversational, 
?chewing-the-fat? QSOs using their bug type key. This is an opportunity 
to exercise, share and exhibit your personalized fist. This is NOT a 
contest. However, there is a very easy and quick registration form found 
athttps://w6sfm.com/bug-roundup/. Once you've optionally registered for 
the event simply Call "CQ BR" so folks know you are a Bug Roundup 
Participant.? So lets grab that bug, clean those contacts, and let?er 
fly! We want to hear that ?Banana Boat / Lake Erie Swing" or that 
commercial KPH/WCC quality fist.

Reserve the date! The event begins on Friday May 18th (00:00 UTC) and 
concludes Sunday May 20th (00:00 UTC)
That's 5:00 PM Friday evening until? 5 PM Pacific Time (LOCAL)

For more information, to register your station, and to help assist in 
spotting, potentially increasing QSOs, an On-line chat window link can 
be found near the bottom of Bug Roundup home page located at 
https://w6sfm.com/bug-roundup/? We hope to hear you all on the air! 73,

Right -- and that fits your voice. Some voices need more bass cut, 
others may not need the boosted highs. Like I've always said, my 
suggested settings are a starting point.

I was informed via e-mail by a fellow ham that my CW signal from my KX3 was splattering about 11k. Although this is the only report I have even received like this, and may be an issue on the other side, it still does concern me.

I do not have another radio where I could transmit into a dummy load and listen. 

Has anyone seen this issue on a KX3? Anything I can check?

Thanks and 73,

Roger,

Were you operating at home on a good power supply?  Or were you on 
batteries that may have become discharged below their limit?  The supply 
voltage may be a factor.

A properly operating KX3 will not splatter, so the problem may be on the 
receiving end.
Can you borrow a receiver or transceiver from a local ham, or take your 
KX3 with the dummy load to his shack since yours is portable?
If you do that, make certain you do not overload the monitoring 
receiver.  Place a short wire antenna on the receiving end and adjust 
its distance to the dummy load so the signal is S-9 or a bit less.

If you do find a problem, email support at elecraft.com.
One thing I might suggest is to use the VFO B Alternate Displays to show 
the voltage during transmit.  If it drops substantially, that might be 
one possible cause for that behavior.

Don W3FPR

Thanks Don,

I?m on a Pro Audio Engineering supply output is 13.5 key down at full output.

Although not a be all tell all, I was monitoring RBN at the time to see where I was being heard and it was reporting my frequency correctly. 

THanks!

Roger,

OK, that rules out the power supply question.

You did not say which band, or the proximity to your email associate.

There are other weird possibilities.? A corroded connection in his 
antenna/feedline system or yours which can act as a diode for instance.
He was close enough for you to overload his receiver.? If he was using 
some of the SDR receivers, they can overload easily.? What band?? How 
strong was your signal at his QTH?? Many unanswered questions.

Don W3FPR

It also matters what receiver the other person was using and I'd bet a 
buck that their noise blanker was on. My mobile rig (another brand) is 
notorious for hearing garbage (but lower noise) with NB on (because it 
bypasses a portion of the rx chain).

While it's disconcerting, more information is needed before fretting 
over one report.

You might be able to use a remote SDR radio for your tests, there are 
several online that anyone can access.

Message-ID: <1525824560142-0.post@n2.nabble.com>

What is the purpose of opposite sideband nulling with the PX3?
I was able to do every band except 50Mhz.
On 50 I was not able to get any change at all. The other bands nulled fine.
Is there a factory setting I can use on 50Mhz?
Tnx,

Start with the Elecraft K3S manual section on DATA modes with soundcardx. 

Don?t worry about the time on the radio, the important clock is the one on the computer. TX and RX must start on time with everyone else. Rest the correct time just before each session from Windows clock settings or install a net clock service. 

Once you have the computer and radio setup and talking to one another and you audio drive to radio set correctly, and DATA mode should drop right in. 

If in doubt, see Don?s website (wa3fpr.com) for more info.

Don, thank you.

With some copper braid solder wick to remove a bit of the fillets on the
joints on both boards, and after using my new Xcelite 170M shears, the
control board can be secured without an insulating sheet between it and the
front panel board.  I may still use that sheet of plastic there, but the
new configuration is *much* better than when I first wrote.

That is www.w3fpr.com.
Scroll the left column to the lat article and click on the link for the 
how and why of setting the audio level for TX 4 to 5 bars on the ALC meter.

I am much older than the assignment if "WA" callsigns.  Got my 60 year

Mark,

Put the plastic sheet in anyway.? In your case, it may be overkill (good 
job on flush cutting BTW).

Hi ... In the KXAT2 menu, there is an option to check relays:? In ATU MD 
Modes L1-L7, C1-C7 and Ct are used to test the KXAT2's relays and 
L-network. However, I dont see any detailed infos of how to use it and 
what results should be expected ??

Any information would be welcome.

Thanks de Pierre VE2PID

No, the Amazon Basics batteries are not the same as the Eneloop Pro. For one thing, they are 2400 mAh instead of 2550 mAh. The best bet is that Amazon Basics batteries are the previous version of Eneloops, made in the old factory. But that is a guess.

Personally, I?m not interested in saving $13 on batteries for a thousand dollar radio. Spend the full $32 for Eneloop Pro.

Use these:

I am a happy Eneloop customer; however, I'm also evaluating - and having a
productive time with - the Bonai brand from Amazon; specifically these.
http://a.co/6KSjWJP

Specs are advertised as 2800 mAH, low self discharge.

How do they test for actual capacity? The first Q&A on Amazon says these 2800 mAh batteries actually tested as 2000 mAh. That is believable, since they are about half the cost of the Amazon Basics batteries.

I've had good results in a number of applications with any of the 
"pre-charged" NiMH.

"pre-charged" is the key.  That's the normal marketing-speak for 
low-self-discharge.

Eneloops are a very safe bet.

Pierre,

You can test the inductors and capacitors using these menu entries. Here?s a general approach:

1. Connect a dummy load to the antenna jack.

2. Set the KX2 for 40 meters, about 3 watts. 

3. With the ATU in BYP (bypass) mode, a TUNE should report SWR of 1.0.

4. Selecting ATU MD = L5, L6, L7 or C5, C6, C7 should make the SWR go up (larger the reactance, the greater the SWR change).

5. L1-L4 and C1-C4 can be tested in the same way, but you?ll need to use a higher band, such as 17 meters, to clearly see the impact of these smaller reactances.

6. I believe that the Ct test position also throws in a capacitor and possibly an inductor to see the effect of switching the network from C-in to C-out. This is likely to be observed best on a higher band.

73,

Please help, it must be 78-year-old pilot error.

Using the K3 Utility I programmed CW message 1 with a CQ message.
I programed CW message 2 with 5NN. I then saved both messages.

When I tap Message 1 I get a row of dashes and RX EQ 1 displayed.

When I tap Message 2 I get 10db and ATTEN displayed.

I am in CW mode and of course no playback.

Bob,

How old is your K3?? Your description sounds like an occasional problem 
I experience ... I tap one key [say PRE], and something else happens.? 
I've been told that replacing the pins on the FP connector with gold 
plated ones will correct the problem and that Elecraft supplies them 
free, but I haven't done it yet.? I've also found that those switches I 
use the most stay more reliable than those I rarely use.

Try really TAPPING the Mx switches ... hard.? The switches behind the 
panel are not hermetically sealed, and I find that really positive 
action on them will correct the problem or at least make it rare.? You 
may need to fasten your K3 to the desk with a couple of tabs of 
sticky-back velcro to be able to make the switch actions positive enough.

If it really IS on your signal and not an issue at the receiving end 
[more likely], that sounds like arcing in your antenna/feedline system.? 
Arcing at 10 W seems strange, but it can be "micro-arcs" inside a poorly 
assembled connector. Before tearing anything apart, I'd arrange for a 
test or two with others.? I would be very surprised if it had anything 
to do with your KX3.? For some reason, human nature is to always assume 
the worst for a cause.

 > The owners manual is of no help.

Have you actually read the KPA-500 Owner's Manual?

Use the "K3 Enhanced cabling" diagram on page 22 but substitute a
cable made according to the instructions in "Icom Cable Connections"
(page 18) instead of the DB15HD/DB15HD cable used with the K3.

As an alternative, you can allow the KPA-500 to band switch based
on detected RF and use the "Basic Cabling" diagram on page 20.  In
that case you will want to use two RCA connections - one between
the "SEND" jack on the IC-7300 and PA Key on the KPA-500, the other
between ALC Out on the KPA-500 and ALC jack on the IC-7300.

Regardless of which (basic or enhanced) cabling you use, be sure to
connect ALC and set the KPA-500 ALC output level as documented on page
10 to prevent the Icom transceiver from over driving the KPA-500 if
the Icom "Power" level is set too high.

Everything you need is in the KPA-500 Owner's Manual if you simply
study it.

I used a KPA500 with a Yaesu transceiver and it worked very well just
letting the amp's RF sensor switch bands. I did not use an ALC cable.

I found that the standard Eneloops were better for my KX3 than the Eneloop
Pro. While the Eneloop Pro has a higher total capacity at lower rates of
discharge than the standard Eneloop, my samples had a higher internal
resistance than the standard Eneloop. That translated into a greater
voltage sag when operating at 10 watts with the Eneloop Pro cells compared
to the standard Eneloops, and so a shorter period of time before 5 watts
was maximum transmission power limit, and end of useful charge even at 5
watts came more quickly with the Pro cells compared to the standard cells.

I'm sorry I don't have more hard numbers to present, and perhaps I just had
a bad batch of Eneloop Pro cells, but it does make sense to me that in
order to get 20% more capacity at low discharge rates, internal resistance,
which is more critical at high discharge rates, might have to be sacrificed.

It's certainly OK to HOOK UP the ALC cable, but it's VERY BAD PRACTICE 
to DEPEND on ALC to set power out.? Doing so is a recipe for terrible 
clicks and splatter. ALWAYS set power using the output power knob on the 
transceiver. The ONLY virtue of ALC is to protect the power amp from an 
operator screw-up, or from something going wrong in the antenna system.

It takes about 25-30W to drive a KPA500 to full power. I'd start with 
the rig at 20W and increase the power slowly until you get the power you 
need. And, of course, much less for our permitted 200W on 30M.

FWIW, I've never used band data with my KPA500, only the AMP KEY cable. 
The KPA500 (and KAT500) are VERY good (and fast) at detecting RF and 
changing bands. All it takes is a dit or a tap on the mic.

That's the point.  The ALC cable protects the KPA-500 when the operator
"spaces" and leaves the exciter power control at full power (100+ Watt)
level.

 > It takes about 25-30W to drive a KPA500 to full power.

Therein lies the case for a 4-6 dB attenuator inside the amplifier.
The attenuator can be left in-line and the exciter can be operated
at its normal (100 W) output level without concern for overdrive
and/or damage.

I'm an infrequent user of data modes. I'm trying to use FT8 with the 
latest version of the WSJT-X software. Sound card input is via LINE IN. 
I'm using DATA A mode.

Everything works OK on transmit except that intermittently the K3 output 
falls to zero even though the sound card audio output level isn't 
changing. The VOX stays on, so the K3 is "hearing" the audio. ALC 
usually but not always falls to zero from the 4 bars level. Even 
weirder, if I turn the MIC gain (LINE) down to zero and back up again 
the output and ALC come back up to normal.

Is this a hardware fault? A software fault? Or something even weirder?

My K3 was working perfectly a few hours ago and had been powered on with 
no config changes.

I just tried it and it develops no RF power (either through audio input 
or using "Tune"), and does not demodulate signals.

The P3 shows an active band, so things are OK to that part of the IF, 
and the signals move around as expected on the display when I tune. When 
I change bands I can see display changes that indicate that everything 
is right up to the P3 take-off point.

I get a hiss that changes volume with the AF and RF gain controls, and I 
get beeps when I press buttons as normal so the audio amp is OK.

It fully responds to computer control and reports the f/w versions 
correctly.

I have tried shutting it down and removing power for 30 Seconds.

Has anyone seen this problem before?

Thanks

I concur that the RF sense works very well, at least it does with an
external antenna switch and reasonably good antenna SWR.  I am not sure
what happens if you also use the KAT500 as an antenna switch or your
untuned SWR is very bad.  Does the amp fault during this first dit?

John,

The amp is bypassed if the KAT500 needs do do any tuning or switching, 
so I suspect the amp will not fault.

That is why you run the keying line first to the KAT500 and then from 
the KAT500 to the KPA500, so the tuner can disable the amp.

The type of radio might matter for a fix for the problem.

If wsjt-x is set up to use CAT control from the computer, it 
will use CAT to set the radio into transmit mode, so the fact 
that the radio is in transmit mode doesn't mean that VOX has 
been activated. If this is the case, it is possible there is a 
problem with the sound card/cable(s).

Hi Bill,

That's an interesting theory but the evidence doesn't support it. If I 
turn off VOX then WJST never puts the K3 into transmit. I looked and F2 
in WJST-X has "VOX" selected under the Radio tab.

The more I mull this over the more the effect of turning the Mic pot 
down to zero and back up again to temporarily clear the fault the more I 
suspect the K3 firmware.

I've downloaded the latest microcode from electraft.com. So far this 
evening the fault has not reappeared. Time will tell.

Alan,

Where do you have the LINE gain set?
It should be somewhere at a mid-range setting.
If it is set to the low or high regions, set it mid-range and adjust the 
audio level with your soundcard volume control in the computer.

Don is correct (as usual). The KPA will first see the band change, perform that task, then try to amplify at the desired frequency. If it then sees a bad reflected power level it will wait for the KAT to do something (which means removing PTT, then performing its own correction, then re-enabling PTT). If it still sees a bad reflected power level (perhaps there is no KAT), then it will start the remediation process which may end in a fault. 

Note that the KPA500 watches reflected power, not SWR (unless SWR is _really_ high). This means that at full output it will object to SWR over about 2:1, while at lower power (say 300 watts), it will allow a higher SWR. Reflected power over about 50 or 60 watts is where it starts the remediation process.That process includes inserting attenuation at the front end (which should also lower the reflected power level) and ultimately in a fault if the attenuation doesn?t do its task or the reflected power is deemed way to high to handle.

So the real answer is that unless you send CW extremely slowly, the KPA500 will perform the band switch and continue monitoring the signal during that first dit, but you probably will not see anything like a fault until many characters down the QSO.

Enjoy the KPA500!

Jack, W6FB

Hello Don,

LINE 20. And ALC 4 bars with 5th one flickering, as was recommended an 
aeon ago. Oh, COMP 0, although I don't think that has an effect on DATA A.

It is/was frustratingly intermittent, making fault finding a royal pain. 
So far this evening with the new microcode the K3 is behaving itself.

"That's the point. The ALC cable protects the KPA-500 when the operator "spaces" and leaves the exciter power control at full power (100+ Watt) level."

My experience, and I have 10 Hz logger data, shows that the amp alarms, sets fault FL06, and drops into standby mode with no change in the ALC voltage level being observed.

I didn't set out to investigate this but my logger was running when I accidentally tripped FL06 on 6 meters this afternoon.

It appears to me that ALC only provides protection if the normal over-drive protections fail.  Currently the ALC voltage only feeds my logger and is not connected to my TS-590S.

Andy,

If you do connect the ALC, check the maximum drive power that you need 
for each band and do not exceed it.  In other words, do not drive the 
amp into ALC.

Using ALC to control the transceiver drive power will result in 
overdrive and distortion.  You can hear that distortion on the bands.

Should you upgrade to an Elecraft K3, you can set a per band drive level 
for when the amplifier is active and when it is bypassed.

73,
Don W3FPR

Hi all,

I have this for sale, shipped USPS anywhere in the US for $50. It sells new
for $125. This is *not* a directional coupler, just a sampler, useful for
getting a scope or spectrum analyzer view of your transmitted signal.

Here is the technical specification: http://preciserf.com/shop/hfs-1-5/.

I prefer payment via Paypal.

I?m experiencing the ATU having to make adjustments sometimes at the start of a transmission after the ATU has already been properly setup for the antenna and band.

I sold my AX1 years ago. It looked great and worked well, but I never used it on stage ever. Ended up selling it for more than I paid for it new!

Hi Les

I also noticed the phantom SWR indication (jump to 3.4:1 on my amp, 
displayed after transmitting - in Rx mode) that has only occurred twice, 
and those times when the temp approached 60c. The output does not seem 
to be affected - power level stays the same, and no fault condition gets 
triggered. My external SWR/Power monitors also remained unchanged, so I 
am thinking it is a display-only problem that is internal to the amp.

To try and avoid unexpected ATU retuning, studied the specs for the ATU 
memories (page 17 of the preliminary doc) and methodically spun the VFO 
across every band, pre-recording in ATU memory the settings for every 
band/segment based on its intervals (10KHz, 20KHz, 100KHz, 200KHz). 
Thereafter I just let the amp decide what it needs to do when changing 
bands/frequencies. Have not witnessed any re-turning.

Les,

Possibly "power drift" in your antenna? Sometimes trap antennas have ceramic 
capacitors which drift under high power. Try a dummy load, etc.  I think the 
SWR threshold point at which the auto tuner makes correction is adjustable 
in the amp. Try setting it up a little higher? Please let us know...

If the tuner is like the KAT500, you should switch to Manual operation 
after you have trained it.  Then, it won't be allowed to try re-tuning 
with every little blip in power.

Les,

We?re virtually certain this is a firmware issue affecting only the bar graph. Once it has been corrected, we?ll issue a new release. The indication has no other implications, so you can keep on using the amp normally.

The M1 - M4 switches can be used for two purposes:
(1)  CW memories; and
(2)  programmable functions or macros.
Might you have previously assigned some of them for such a purpose?

>From a version of the K3 manual:
Any M1 ? M4 switch that is used as a

tap REC, then tap the buffer you?d like to restore

Mark,

There definitely will be orders taken for the KXPA100.  And there will 
be show specials and typically free shipping.
Whether any particular products will be for sale there is questionable.
If buying (not ordering) at Dayton, you will have to pay Ohio Sales tax 
if there is the KXPA100 available for sale.

In other words, I do not know which products will be sold so you can 
carry them home. But there will be savings, at least free shipping if 
nothing else.

Elecraft does not typically say what will be sold on-site until they 
actually pack things up for the show.

Subject: [Elecraft]  K3S - Help me decide on which options to purchase

Hi guys,

I?m looking to purchase a K3S in the near future and I would like y?alls input on which options to include. I had a K3 before however due to financial issues I had to sell it. Now I want to get back into radio again and I want to get a K3S.

I mostly get on the OMISS Nets on 40m however I want to also learn how to Dx on 20m (and other bands?) soon. And I want to eventually start CW after I teach myself how to CW. Those are my near term goals (next two years). One consideration is that whatever I include when I order the K3S will be installed and calibrated by Elecraft at the factory. If I added options later I would have down time and cost of shipping and cost of the work as well (I don?t really want to do it myself even though I did build my first K3).

I am likely going to include the 2.7 filter.

Other possible options are:

Other filters
General Rx
Second Rx
???


Thanks,
Michael

I've been using a P3 with my K3 with a video display for several years.
I'm planning to purchase a K3S and would be willing to buy a second P3 if I
could figure out a way to combine the output of the two P3s on one screen,
either horizontally or vertically, for simultaneous viewing.  Has anyone
been successful in doing this?  Not keen on having two VGA monitors plus my
computer monitor due to limited desk space.

Thanks and 73,

Dennis, I use a Samsung display that has 2 HDMI inputs and allows the monitor to display 2 inputs side by side.  You may even be able to find a monitor with 2 VGA inputs that supports PIP.  VGA to HDMI convertor cables are plentiful as well.

The secret is a 2-input display that support PIP.  Mine is a current Samsung 28? 4K display and I run the Mac on one side and the Windows 10 NUC on the other,  Works well.

Great idea, Michael.? But with one important possible gotcha -- 
virtually all of the power supplies for monitors like this are 
switch-mode types, and almost all generate RF noise. Several years ago, 
we were lucky to identify several Samsung models that run on a nominal 
14VDC, and that work fine on the 12-14VDC that most of us have in our 
shacks (or on older linear 12V wall warts). Most newer models run at 
higher DC voltage, so to kill the noise they generate, we much find a 
suitable linear power supply for that voltage.

BTW -- someone gave me a Samsung with touch controls because it was an 
RFI nightmare -- the monitor itself generated lots of noise AND the 
display went nuts in the presence of RF.

Michael,

For the options, you will have to look at your station and your 
operating desires.  You gave no specifics, so the answer could be "All 
the options".

Do you have all resonant antennas?  If not, add the KAT3A.
Do you operate in contests or other situations where there may be strong 
stations near your fequency?  If so, you will want the 400Hz CW filter 
and possibly the 2.1kHz SSB filter.
Do you want to do DXing where the DX is working split?  If so, you will 
want the KRX3, for best results - listening to both the DX and the pileup.
Do you want to do continual calling in a voice contest and save your 
voice?  If so, add the DVR.
Do you want to operate FM?  If so, the 13kHz filter is needed.
Do you want to operate AM or ESSB?  If so, either the 6kHz or 13kHz 
filter will be needed.
Do you want to do SWLing?  Then add the KBPF3.

The 2.7kHz filter comes as standard, but you can upgrade to the steeper 
skirted 2.8kHz width.  You may want a P3 to go along with the K3S for 
all but casual operating.

In other words, order for the operating needs that your desires require 
for the best ease of operation for you.

You may also find one of the Packages listed on the website to your 
liking, look them over.

73,
Don W3FPR

Jim, I have two Samsung monitors.  One is a 23? 1920x1080 with one VGA and one HDMI input and the other is the 28? 4K display with one Displayport and two HDMI inputs.  Both have switch mode power supplies and I have never been able to identify either as a source of noise on my Flex 5000, Flex 3000, FLEX 6300, SunSDR2 Pro, Sun SDR2 NANO, QX1R, KX3 or K3s.

I have been quite fortunate in this regard as they have both served me well.

Worse even is that MOST newer monitors now have INTERNAL power supplies.? They are switched, multi-voltage output, and almost impossible to hack....
I was going to hack my monitors and put a linear dc supply before the transformer/regulators....? no joy.? Only way to make the monitors DC? only in my case is to find the various voltage output rails and cut in individual DC supplies in and completely hack the existing PS circuitry out of the design....? not at all a trivial exercise.
I will pick monitors better and have the DC supply plan in place for the next monitor go around....? <frown>
Same frustration in trying to hack most laptop power supplies....? 18.5 vdc nominal, but with special circutry that cause the battery/laptop/charger to talk....? no talk, and the PS won't charge the battery.... yadda yadda...
Best case scenario is to just power the laptop directly from battery pins...? BUT you STILL have to then trick the laptop into recognizing the DC PS as a battery.
Dell won't even think about talking to me about the battery pinout and the power good logic.

I downloaded the latest K3 firmware and the fault has not reappeared in 
the past 24 hours.

Another thought struck me. The external USB sound card I use for FT8 
might be playing tricks on me. I've had it disappear from the Control 
Panel Sound menu for no apparent reason in the past. But who knows what 
Windows does under the covers.

Thinking of replacing my Pigknob [which doesn't work when I'm running

1.? If I'm reading the product description correctly the only connection 
between the K3 and KPod is a cable to the RJ-45 jack on the bottom edge 
of the Front Panel under the RIT/XIT?

2.? Is that cable supplied with the KPod?

3.? Will the KPod control the remote radio via RemoteRig RRC-1258?

4.? Assuming #3 is a Yes and I'm operating a remote K3, where are the 
macros stored?

OK, that's more than a couple, sorry.? TIA

Since you've had a K3 before, you should have some insight as to how if 
fulfilled your needs.

The radios are very similar, I have both and for the most part don't see a world 
of difference, other than the old one is more reliable.? The K3S preamp is 
better if you care about the higher bands.

I am mainly interested in chasing DX.? Because I have a KPA500 and KAT500, I 
don't have a tuner in either radio, although obviously, the old K3 predates the

I would add to that my comments:

I think if you are chasing DX on sideband it might be helpful to also get either the 1.8 or 2.1 filter.  These filters are effective at blanking out adjacent stations so you can hear the weaker DX signal.

I would not be afraid to go under the hood and add things as long as you don't have the second receiver.  In my opinion the second receiver installation is very tricky.  Clearances are very tight with the second receiver and installation is tricky.

Since you've had a K3 before, you should have some insight as to how if fulfilled your needs.

The radios are very similar, I have both and for the most part don't see a world of difference, other than the old one is more reliable.? The K3S preamp is better if you care about the higher bands.

I am mainly interested in chasing DX.? Because I have a KPA500 and KAT500, I don't have a tuner in either radio, although obviously, the old K3 predates the external amp/tuner.? Also, I don't have a second receiver.? You can work DX, even with wide splits without one.? I do it all the time.

I have a K3S with the built-in antenna matching unit.
I have a variety of wire antennas strung through the trees.
For SWR below 1.5 or so, I bypass the antenna matching unit.
But at higher SWRs, I use it to reduce the strain on the finals.

Bypassing the matching unit avoids inherent losses, but is it putting a

Can I just monitor the PA Temp as a guideline as long as I'm getting the

I primarily operate 25-50 watts digital modes these days.

Note: this set up also has a usb keyboard and mouse switch built in as well. So I can use one keyboard for FSK, PSK or CW between two K3/P3s.

Correct, if your K3 is appropriately configured. IIRC, there is a necessary
mod to provide adequate power that isn't in all earlier K3's. I run my
K*Pod with a single cable. N.B. It's a "special" cable with no connection
between the Pins 1, not a standard 6-conductor RJ45 cable.

Yes, I do it all the time. I'm using a full K3 as the remote control head.

They're stored on the remote K3. The eight buttons on K*Pod launch 16
macros (Tap vs. Hold) stored on the radio. In your case of operating a
shared station, you might want to coordinate macro definition with the
station owner.

That doesn't mean that they're not noisy -- most of us are surrounded by 
dozens of noise sources that blend together and make any single source 
hard to hear. Your monitors could be noisy,? but the rest of the noise 
covers it up. Have you probed around them with a portable AM radio tuned 
to a clear spot near the high end of the AM broadcast band? I use a 
Kenwood TH-F6A talkie, which covers from below the AM band to nearly 1 GHz.

All of us can do ourselves a favor by implementing a "search and 
destroy" mission for RF noise sources. These two links provide a lot of 
practical advice on how to do it.

Message-ID: <20180511230650772@smtp475.redcondor.net>

I am mostly a CW op so will leave it to others to offer suggestions on SSB filters.  I have owned or operated rigs with various narrow CW filters and none sound anywhere near as good as my K3S with my 400 Hz filter.  If you are interested in even a moderate amount of CW, I think this filter is a good purchase.  The K3S sounds just perfect with this filter, and you can narrow down the passband even further with the DSP filtering.  On other rigs I often needed to switch in something like a 200 Hz roofing filter when the going got really rough in a contest or DX pile up.  My plan was to add the 200 Hz filter to my K3S, but now doubt that I will even bother.  If CW contesting is a big interest of yours and if you have plenty of money in your budget, possibly the 200 Hz filter will help occasionally.  I have a 700 Hz filter, which INRAD offers from time to time, and thought it would be my favorite filter for casual CW operation, however since the DSP with an SSB filter, or the 400 Hz filter sound so good on CW, I do not consider it necessary.  
      I believe you can upgrade to the 2.8 kHz from the stock 2.7kHz filter for a modest cost which some SSB ops consider worthwhile.  I use resonant antennas, however I have the internal tuner since I want to occasionally venture into parts of bands where my antennas have higher SWR.

I believe the K3(s) starts folding back PO at an SWR of 2:1 or higher with
100W out.
At 25 - 50W out you may never get to fold back unless your trying to use a
light bulb for an antenna (tribute to N6BT).

One thing to consider on the sub-receiver...
If you don't have a dedicated receive antenna, you may find the sub-receiver's performance lacking. It depends on how you want to use it.

If I added options later I would have down time and cost of shipping and cost of the work as well (I don?t really want to do it myself even though I did build my first K3).

I am likely going to include the 2.7 filter.

Other possible options are:

Message-ID: <BFB17AC8-0E4E-4D76-B645-EF4E14D3B25B@earthlink.net>

Curious if the duty cycle of a stock (no aftermarket heat sink) KX3 differs when transmitting over the 2m transverter, versus keying up on the HF side of the rig?

HF can go as high as 15 watts, of course, whereas the 2m transverter maxes out at 3 watts.  One might imagine that the very modest 2m output would translate into an extended duty cycle, but that has not been my experience.  When transmitting, the 2m module rises in temp quite rapidly, to the point that I now monitor PA temp on the display when running our local VHF net.  Backing down to 1 watt helps, but at an obvious price.

I?d be interested in any thoughts anyone has on the thermal relationships at play here.

Normally they don?t charge till they ship.  Some early KPA1500?s were ordered with Free Shipping if paid in full at order.  May be other perks but it gave them ?working cash? up front. Don?t know if this is currently available. Phone call to Elecraft rather than reflector should clarify.

Make sure you are running the KX2 Utility with the PC connected via the KXUSB cable to the turned-on KX2.  All that must happen before trying to communicate between PC and KX2...you won't be able to select the COM port until then.

If you put down a deposit when you ordered  (Full price/$3000/$1000), your card was charged with that deposit when you placed the order.  Prior to shipment, Elecraft will charge the Balance to your card to total the amplifier's cost, $5995.  Those that put down full price as a deposit had free shipping (cost approximately $95 for me).

I don't think the new orders have the same process, but as far as I know, the introductory price still applies.  I would assume they will charge for new orders just prior to shipment.   I hope someone from Elecraft will post and give the actual process for new orders, as I do not know that for a fact.

Thanks for all the replies and good advice!
I?m going to get the K3S with the antenna tuner (I?m just using a wire strung between two trees) and the 2.7kHz filter. I?ll add filters as I see the need and the other stuff too like a DVR, second Rx, etc. I?ll just wait until my experience progresses and I really feel like I would benefit from the various options. I was reminded that the parts are calibrated at the factory ready for me to install them at a later date if I wish and that its not that hard until you get the second Rx so I can add filers and other options myself as needed. Probably order the ?Casual User? package as its slightly cheaper to go that route than a la cart. I still have my old antenna, mic, headphones, power supply, etc so just need the radio.

Thanks again for all the emails!

If I added options later I would have down time and cost of shipping and cost of the work as well (I don?t really want to do it myself even though I did build my first K3).

The KPod can also be run with its own power supply. I found the 
modification to my K3 easy, but I also decided to practice SMD 
rework and remove the high value resistor and replace it with 
the low value resistor instead of just paralleling them. (Yeah, 
I know, I was just showing off.)

The bottom line is that you have a bunch of choices how you 
connect it and power it. I went for minimum cables.

Michael,

Elecraft has them, shipping off the shelf.  You can select from the list 
of options, and have your custom configured K3S with options configured, 
built and tested, calibrated before shipment.
If you decide to order a kit, the boards will be pre-calibrated.

73,
Don W3FPR

Guys?

My KX3 is currently connected to my KXPA100 and is used to drive an Ameritron AL-811. The setup is as follows

KX3??KXPA100??AL-811??MFJ-994B tuner?Daywa CN901?-Hexbeam

The KX3 and the KXPA100 auto-tunners are off.  I tune with the MFJ with the amp in bypass.
The Hexbeam is resonate at 1.5 or less before tuning.  I us an Ameritron ARB-704 to key the amp.

When I transmit the SWR LEDs On the KXPA100 are peaked out. 
Daywa to the antenna shows less than 1.2 SWR.  

Am I doing something wrong here.  I am using about 20W from the KX3 to drive the Amp to about 450W



Thanks

Given you already have an SWR of 1.5 or less with the hexnbeam, the MFJ tuner is just adding loss.

It could be the KXPA100 doesn?t like the AL-811 input circuits.  If the SWR is low (on the KXPA100) with the 811 bypassed, and high when the 811 is in line, then I?d suspect the 811 input.  You could try putting a dummy load on the amp, the Daiwa 901 between the KXPA100 and the amp, and see how the KXPA and Daiwa compare.  Or turn on the antenna tuner on in the KXPA and see if it can tune out the reactance of the amp input.  You may just need to adjust the 811 input network for a better SWR.  The networks on my AL-1200 aged into an SWR of around 2.5.  I always ran my K3 autotuner when driving the amp ? too lazy to take off the 927 screws to remove the AL-1200 cover, slide it back, and adjust the input networks.

Probably a silly question:? Did you turn off the tuner in the amp 
(bypass it)?? If not, it should be off.

Hello,
      I noticed this power output anomaly today while trying to work the NSS station. My K3 was in split mode, transmitting on 10.113.5.  While I was listening on 9.448 (the NSS transmit frequency), I noticed that even though my K3 power level was set at 100 watts, the K3 was only putting out about 20 watts. Two different power meters (the K3 internal meter and an outboard LP-100A) gave me the 20 watt reading.
     When I listened on my transmit frequency of 10.113.5, I was getting the full 100 watts out.  A quick investigation showed that as I tuned my listening frequency down, I got the full 100 watts out until I got to about 9.850 mHz. When I listened below that, K3 transmit power on 10.113.5 dropped immediately down to 20 watts.
     Not sure why I am seeing this?  One additional note ? I hear a relay click inside the K3 when I tune my receive frequency below 9.850. I see the anomaly with the subreceiver either on or off.

Message-ID: <5D12B49E-87AB-4C3D-A84F-29F000A2D0CA@law.du.edu>

Getting closer to placing an order for a KPA-1500 -- --  electrician is, at last, coming Monday to see if or how 240 VAC can be brought to the shack.  Meanwhile, in reading the KPA1500 Manual I saw no mention of a tilt stand, and the photos don?t show one.  Is there, or could there be?  Weight should not be a problem.  The KPA1500 RF deck weighs 22 lbs, compared to almost 31 lbs for the KPA500 with a KAT500 on top.  If there is no official tilt stand, could the front feet be propped up on home-made props to have the angle match the neighboring K3 and P3, or would that degree of tilt restrict access for the lower rear panel connectors?  I can?t tell those detailed dimensions from the pictorials . . . .   Any other reason not to do something like that?

You could try putting a dummy load on the amp, the Daiwa 901 between the KXPA100 and the amp, and see how the KXPA and Daiwa compare.  Or turn on the antenna tuner on in the KXPA and see if it can tune out the reactance of the amp input.  You may just need to adjust the 811 input network for a better SWR.  The networks on my AL-1200 aged into an SWR of around 2.5.  I always ran my K3 autotuner when driving the amp ? too lazy to take off the 927 screws to remove the AL-1200 cover, slide it back, and adjust the input networks.

Hi Ed,
You don't have a transmit problem at all. It is not an anomaly.
The amateur band starts at 10.100 MHz. You shouldn't be transmitting below that frequency. I'm surprised the K3 allowed you to do that.
The K3/K3S gives an out of band error and won't transmit beyond some amount below and above the amateur band limits, I believe allowing for MARS frequencies.
The reason for the relay click and your lower output is due to switching of the bandpass filters in the K3. They are not designed to transmit down there. This is also why you are seeing a reduction in receive sensitivity. You need the BPF3A to receive outside the ham bands. Again, because you are limited by the bandpass filters for the ham bands in the K3.
If you have more questions, let us know here on the reflector and we will try to answer them for you.

Subject: [Elecraft] K3 Strange Power Output Problem

Hello,
      I noticed this power output anomaly today while trying to work the NSS station. My K3 was in split mode, transmitting on 10.113.5.  While I was listening on 9.448 (the NSS transmit frequency), I noticed that even though my K3 power level was set at 100 watts, the K3 was only putting out about 20 watts. Two different power meters (the K3 internal meter and an outboard LP-100A) gave me the 20 watt reading.
     When I listened on my transmit frequency of 10.113.5, I was getting the full 100 watts out.  A quick investigation showed that as I tuned my listening frequency down, I got the full 100 watts out until I got to about 9.850 mHz. When I listened below that, K3 transmit power on 10.113.5 dropped immediately down to 20 watts.
     Not sure why I am seeing this?  One additional note ? I hear a relay click inside the K3 when I tune my receive frequency below 9.850. I see the anomaly with the subreceiver either on or off.

Hi Mark!  I am transmitting on 10.113, and I do not change this.  I am in Split mode, listening for NSS (who is transmitting on 9.448).  I am only seeing about 20 watts out, even though the K3 Power setting says 100 watts.

If I change my RECEIVE frequency ? not my transmit frequency ? once I get above 9.850 on RECEIVE, my power out returns to the expected 100 watts.

I ran into this today too, different frequencies though. I recently installed the KBPF3 module and have it enabled full time. I think what happened is the VFO-A frequency sets the BPF segment to be used and with the wide split, it's not the right one for the VFO-B TX frequency to use. Therefore you don't get enough drive through to the amplifier stages. The K3 will not switch BPF segments to go between RX and TX states. I got an ERR:TXG indicating something was afoul in the BPF setup. 

I tried to set the KBPF3 to 'not installed' but botched it since I didn't remember you had to cycle K3 power to reconfigure that option. By then NSS had faded into the noise. Oh well, got 'em on one band.

I saw a demo last night of the FlexRadio bandscope.  It showed the noise
well above, on the Y-axis, the bottom of the display, but the waterfall
didn't show the noise, just the signals on the band.  

 

When I set the REL LVL on my P3 so the noise floor is below the noise, the
waterfall is blue from the noise, making it difficult to see the signals.

 

Can someone enlighten me as to why the displays are so different?

Looks like my K2 could be orphaned for a while because the Apartment
Management's latest  Patrol Harridan decided that my 30-foot-long
"Emergency Antenna" (end-fed wire) from my porch to the nearest tree had
to come down after 4 years - took a lot of looking to see it in the
first place.  I'm not all that sad, because the way it operated, the
outside of the coax shield was the counterpoise, bringing RF into the
radio room that locked up my laptop if I wanted to use it for digital comms.

With that said -- I am considering an Alex-Loop which will meet the
aesthetic requirements of the Patrol Harridan (who fortunately is
"overlooking" the 3 J-Poles) but it is impossible for me to install the
loop on the porch and tune it from the radio room 30 feet and two rooms
away.  Is there any solution for a remote tuner?  Or haven't I looked
far enough?

Hi Jim,

They may be automatically calculating a long-term-average noise floor, then subtracting it from the waterfall. The P3 could do the same thing. But automatic noise subtraction would have the same disadvantage as slow AGC: a temporary rise in the noise floor would mask weak signals for the duration of the averaging time constant.

You can achieve the same thing manually, without the averaging issue. Simply adjust the REF level such that the noise floor is just at or slightly below the line. The waterfall will then be nearly invisible except for signals and higher noise peaks.

Look at the W4OP loop.  The W4OP offers manual and remote tuning options.  I have the W4OP (with manual and remote tuning units) and the AlexLoop The W4OP is the one that gets used the most, although it?s a bit heavier when packed and can?t really be hand held.  Both are nice products.

Hi Phil,
I use a cordless phone, or a cell phone, contact the second phone, and 
tune my loop from about 100 feet for most noise.  Once you get the hang 
of it, you can hit a 1:1 almost every time...

I have a homebrew Alex Loop running now, outside, and doing WSPR.  Go to 
WSPR net, and select NK7Z, then look at the last few hours...  I got all 
sorts of DX yesterday, which you can see by looking at the last 12 hours...

If all of that fails, I will be constructing a 12 foot loop for 40, and 
building a remote tuning device out of a servo and an airplane 
controller.  I can share with you what I end yup with if you want.

73s and thanks,
Dave

I'm not all that familiar with the Flex stuff but in some SDR software 
display systems it is possible to adjust the waterfall sensitivity and 
contrast independent of any spectrum bandscope position adjustment. It 
is often also possible to have any signal levels indicated by such 
displays bear no relationship to any accurate level.The P3 waterfall 
contrast changes with the reference level setting which in itself 
changes with the displayed bandwidth, seems appropriate. Scale will 
adjust the sensitivity I think.

In the situation I have here where it is unusual to have any signals on 
any band at more than S7-8, nearest centre of any appreciable activity 
is several thousand miles away so mostly fairly weak signals, in this 
case I find having the waterfall in monochrome, spectrum display is 
still in colour, to be quite an advantage. It is quite possible to set 
an almost black waterfall with signals barely above the noise floor 
showing as grey marks, often much more discernible than anything on the 
spectrum display.

Hi Martin,

I have a somewhat different solution to your problem, and it consists of 
multiple parts.

First, I set averaging to maximum (I set it years ago, don't ask me 
numbers). :)

Second, I set Scale to 24 dB when I'm not contesting, 32 dB for 100W 
contests, 42 dB for high power contests.

Third, I set reference level so that the noise level as at the bottom of 
the amplitude display , which causes the waterfall to be black where 
there are no signals.

Fourth, I set Tracking Mode ON, so that when I tune, the signals on the 
band stay put as I tune across them. Without this setting, Averaging 
would reset every time the changes frequency.

A major benefit of averaging is that it causes random noise to cancel 
itself out, leaving only signals (and noise that is NOT random). Now, 
both the amplitude display and the waterfall will show only real signals 
plus noise that's more or less stable in frequency, like clocks from 
microprocessors, and "lumps" of noise which may drift a little or a lot. 
Those lumps are generated by power-handling devices like switch-mode 
power supplies and variable-speed motor controllers.

I don't use monochrome display, but I do see signals against a nearly 
black background.

Subject: [Elecraft] K3 Strange Power Output Problem
In-Reply-To: <5af7524e.1c69fb81.71213.ff53@mx.google.com>
Message-ID: <2105056936.237768.1526193374326.JavaMail.root@starpower.net>

Hi Ed, 


We had exactly the same problem with all six of our MARS modified 
K3 transceivers at NSS. 



We were forced to replace our MARS modified K3 transceiver transmitting 
on 9448 kHz with an old FT-1000MP... Only on other bands where our 
assigned MARS frequency was very close to the edge of the ham band did 
the K3 produce near normal RF output power but only if VFO A was 
set to listen just inside the edge of the ham band nearest to our MARS\ 
transmitting frequency on VFO B. 



This is the behavior we discovered with all of our K3 transceivers: 


- Transmitting on 9448 kHz or any other MARS frequency on either 
VFO A or VFO B works perfectly but only when not operating split . 


- Operating split with both VFO A and VFO B set for any 
frequencies within the same ham band works perfectly. 


However -- when selecting split operation -- VFO B RF output power 
steadily drops as VFO A is tuned to receive at an increasingly large 
frequency split relative to VFO B transmitting on a fixed MARS freq. 


It appears that when operating split and transmitting on VFO B on a 
MARS frequency, the K3 bandpass filter associated with the VFO A 
receiving VFO is always selected for use with the VFO B split transmitter 
outside the ham band. When VFO B is tuned to transmit outside the 
ham band (e.g. 9448 KHz and VFO A listening on 10113) the VFO B 
transmitted signal on 9448 kHz cannot pass through the standard 30 meter 
bandpass filter automatically selected by the K3 for use with VFO A. 


Proposed solution: the K3 must dynamically select the proper KBPF3 
bandpass filter before transmitting on a VFO B split frequency outside 
the ham bands. Then the K3 must dynamically switch back the stock 
K3 band pass filter each time the K3 switches from VFO B transmit 
to VFO A receive inside the ham band.. 


This exact same problem occurs on every band, not just 30 meters. For 
example on 80 meters NSS was transmitting with VFO B on 4038 kHz. 
We were forced listen with VFO A set just below 4000 kHz. As a 
result we were forced to ask CW stations to call us just below 4000 kHz, 
an unusual operating practice. If we tuned VFO A to receive on 3530 kHz 
the VFO B transmitter power output on 4038 kHz was dramatically lowered. 


N3CW experienced exactly the same problem when transmitting with 
inside the 30 meter ham band and listening on 9448 kHz. 


Hopefully the capability to dynamically select to proper bandpass 
filter before each transmission can be added to the K3 before the next 
Armed Forces Day Cross-Band Test in twelve months...

Hi Mark! I am transmitting on 10.113, and I do not change this. I am in Split mode, listening for NSS (who is transmitting on 9.448). I am only seeing about 20 watts out, even though the K3 Power setting says 100 watts. 

If I change my RECEIVE frequency ? not my transmit frequency ? once I get above 9.850 on RECEIVE, my power out returns to the expected 100 watts.

Hi Ed, 
You don't have a transmit problem at all. It is not an anomaly. 
The amateur band starts at 10.100 MHz. You shouldn't be transmitting below that frequency. I'm surprised the K3 allowed you to do that. 
The K3/K3S gives an out of band error and won't transmit beyond some amount below and above the amateur band limits, I believe allowing for MARS frequencies. 
The reason for the relay click and your lower output is due to switching of the bandpass filters in the K3. They are not designed to transmit down there. This is also why you are seeing a reduction in receive sensitivity. You need the BPF3A to receive outside the ham bands. Again, because you are limited by the bandpass filters for the ham bands in the K3. 
If you have more questions, let us know here on the reflector and we will try to answer them for you.

Subject: [Elecraft] K3 Strange Power Output Problem 

Hello, 
I noticed this power output anomaly today while trying to work the NSS station. My K3 was in split mode, transmitting on 10.113.5. While I was listening on 9.448 (the NSS transmit frequency), I noticed that even though my K3 power level was set at 100 watts, the K3 was only putting out about 20 watts. Two different power meters (the K3 internal meter and an outboard LP-100A) gave me the 20 watt reading. 
When I listened on my transmit frequency of 10.113.5, I was getting the full 100 watts out. A quick investigation showed that as I tuned my listening frequency down, I got the full 100 watts out until I got to about 9.850 mHz. When I listened below that, K3 transmit power on 10.113.5 dropped immediately down to 20 watts. 
Not sure why I am seeing this? One additional note ? I hear a relay click inside the K3 when I tune my receive frequency below 9.850. I see the anomaly with the subreceiver either on or off.

If you are looking for a high efficiency antenna system, low swr on long
runs of coaxial cable is critical.  The only way to accomplish this on a
wide band basis is to provide a 50 ohm non-reactive load for your 50 ohm
coaxial cable.

Some sort of tuning is needed at the antenna end of the coax.  I developed
"StepperTune" to control an ATU remotely.  Tuning a loop is also applicable
with StepperTune.   For more info, go to www.steppertune.com

I have to admit, operating SPLIT between a ham band and a MARS band that falls outside the nearest ham-band filter isn?t something that occurred to me when writing the firmware. But I can change the filter selection algorithm to accommodate this case as long as a KBPF3 module is installed. 

Technical details:

Since the K3/K3S is a downconversion superhet, we use very narrow ham-band filters. One of the narrowest is the 30 meter filter. 

To preserve the rig?s exceptional dynamic range, we switch the band pass filters with relays, not diodes. This means we can?t switch filters at T/R rates. 

So to handle the case being discussed, we?d have to select the 7-10 MHz KBPF3 filter for both RX and TX.

Charlie N7CAC,

I use my KX3 to Drive a KXPA100 to drive a AL572 into a Hexbeam, with no
problem getting 1KW out.

I use the KXPA100 tuner to ensure a good match to the AL-572 and get max
power out.  There should no need for a tuner with a Hexbeam, or in my view
any antenna with an SWR under 2.0, definitely not need with an SWR of 1.5.
I also use the tuner in my Icom 6700 to drive the AL572 for the same reason.


Recommend you use the tuner in the KXPA100 and see if that helps.

The KPod can also be run with its own power supply. I found the modification
to my K3 easy, but I also decided to practice SMD rework and remove the high
value resistor and replace it with the low value resistor instead of just
paralleling them. (Yeah, I know, I was just showing off.)

The bottom line is that you have a bunch of choices how you connect it and
power it. I went for minimum cables.

Michael,

Elecraft has them, shipping off the shelf.  You can select from the list of
options, and have your custom configured K3S with options configured, built
and tested, calibrated before shipment.
If you decide to order a kit, the boards will be pre-calibrated.

Guys?

My KX3 is currently connected to my KXPA100 and is used to drive an
Ameritron AL-811. The setup is as follows

KX3??KXPA100??AL-811??MFJ-994B tuner?Daywa CN901?-Hexbeam

The KX3 and the KXPA100 auto-tunners are off.  I tune with the MFJ with the
amp in bypass.
The Hexbeam is resonate at 1.5 or less before tuning.  I us an Ameritron
ARB-704 to key the amp.

When I transmit the SWR LEDs On the KXPA100 are peaked out. 
Daywa to the antenna shows less than 1.2 SWR.  

Am I doing something wrong here.  I am using about 20W from the KX3 to drive
the Amp to about 450W



Thanks

Given you already have an SWR of 1.5 or less with the hexnbeam, the MFJ
tuner is just adding loss.

It could be the KXPA100 doesn?t like the AL-811 input circuits.  If the SWR
is low (on the KXPA100) with the 811 bypassed, and high when the 811 is in
line, then I?d suspect the 811 input.  You could try putting a dummy load on
the amp, the Daiwa 901 between the KXPA100 and the amp, and see how the KXPA
and Daiwa compare.  Or turn on the antenna tuner on in the KXPA and see if
it can tune out the reactance of the amp input.  You may just need to adjust
the 811 input network for a better SWR.  The networks on my AL-1200 aged
into an SWR of around 2.5.  I always ran my K3 autotuner when driving the
amp ? too lazy to take off the 927 screws to remove the AL-1200 cover, slide
it back, and adjust the input networks.

Probably a silly question:? Did you turn off the tuner in the amp (bypass
it)?? If not, it should be off.

Message-ID: <5af73f8b.1c69fb81.31c99.e841 at mx.google.com>
Content-Type: text/plain; charset="utf-8"

Hello,
      I noticed this power output anomaly today while trying to work the NSS
station. My K3 was in split mode, transmitting on 10.113.5.  While I was
listening on 9.448 (the NSS transmit frequency), I noticed that even though
my K3 power level was set at 100 watts, the K3 was only putting out about 20
watts. Two different power meters (the K3 internal meter and an outboard
LP-100A) gave me the 20 watt reading.
     When I listened on my transmit frequency of 10.113.5, I was getting the
full 100 watts out.  A quick investigation showed that as I tuned my
listening frequency down, I got the full 100 watts out until I got to about
9.850 mHz. When I listened below that, K3 transmit power on 10.113.5 dropped
immediately down to 20 watts.
     Not sure why I am seeing this?  One additional note ? I hear a relay
click inside the K3 when I tune my receive frequency below 9.850. I see the
anomaly with the subreceiver either on or off.

Meanwhile, in reading the KPA1500 Manual I saw no mention of a tilt stand,

not be a problem.  The KPA1500 RF deck weighs 22 lbs, compared to almost 31
lbs for the KPA500 with a KAT500 on top.  If there is no official tilt
stand, could the front feet be propped up on home-made props to have the
angle match the neighboring K3 and P3, or would that degree of tilt restrict
access for the lower rear panel connectors?  I can?t tell those detailed

Hi Ed,
You don't have a transmit problem at all. It is not an anomaly.
The amateur band starts at 10.100 MHz. You shouldn't be transmitting below
that frequency. I'm surprised the K3 allowed you to do that.
The K3/K3S gives an out of band error and won't transmit beyond some amount
below and above the amateur band limits, I believe allowing for MARS
frequencies.
The reason for the relay click and your lower output is due to switching of
the bandpass filters in the K3. They are not designed to transmit down
there. This is also why you are seeing a reduction in receive sensitivity.
You need the BPF3A to receive outside the ham bands. Again, because you are
limited by the bandpass filters for the ham bands in the K3.
If you have more questions, let us know here on the reflector and we will
try to answer them for you.

73,
Mark, WB9CIF

Hi Mark!  I am transmitting on 10.113, and I do not change this.  I am in
Split mode, listening for NSS (who is transmitting on 9.448).  I am only
seeing about 20 watts out, even though the K3 Power setting says 100 watts.

If I change my RECEIVE frequency ? not my transmit frequency ? once I get
above 9.850 on RECEIVE, my power out returns to the expected 100 watts.

You don't have a transmit problem at all. It is not an anomaly.
The amateur band starts at 10.100 MHz. You shouldn't be transmitting below
that frequency. I'm surprised the K3 allowed you to do that.
The K3/K3S gives an out of band error and won't transmit beyond some amount
below and above the amateur band limits, I believe allowing for MARS
frequencies.
The reason for the relay click and your lower output is due to switching of
the bandpass filters in the K3. They are not designed to transmit down
there. This is also why you are seeing a reduction in receive sensitivity.
You need the BPF3A to receive outside the ham bands. Again, because you are
limited by the bandpass filters for the ham bands in the K3.
If you have more questions, let us know here on the reflector and we will
try to answer them for you.

73,
Mark, WB9CIF

Subject: [Elecraft] K3 Strange Power Output Problem

Hello,
      I noticed this power output anomaly today while trying to work the NSS
station. My K3 was in split mode, transmitting on 10.113.5.  While I was
listening on 9.448 (the NSS transmit frequency), I noticed that even though
my K3 power level was set at 100 watts, the K3 was only putting out about 20
watts. Two different power meters (the K3 internal meter and an outboard
LP-100A) gave me the 20 watt reading.
     When I listened on my transmit frequency of 10.113.5, I was getting the
full 100 watts out.  A quick investigation showed that as I tuned my
listening frequency down, I got the full 100 watts out until I got to about
9.850 mHz. When I listened below that, K3 transmit power on 10.113.5 dropped
immediately down to 20 watts.
     Not sure why I am seeing this?  One additional note ? I hear a relay
click inside the K3 when I tune my receive frequency below 9.850. I see the
anomaly with the subreceiver either on or off.

Hi Ted,
The KPA1500 RF deck does have a tilt stand. I can't tell you how high it is
because I don't use it.
If you want, I'll be glad to check it for you.

Subject: [Elecraft] Tilt Stand for KPA1500?

Getting closer to placing an order for a KPA-1500 -- --  electrician is, at
last, coming Monday to see if or how 240 VAC can be brought to the shack.
Meanwhile, in reading the KPA1500 Manual I saw no mention of a tilt stand,
and the photos don?t show one.  Is there, or could there be?  Weight should
not be a problem.  The KPA1500 RF deck weighs 22 lbs, compared to almost 31
lbs for the KPA500 with a KAT500 on top.  If there is no official tilt
stand, could the front feet be propped up on home-made props to have the
angle match the neighboring K3 and P3, or would that degree of tilt restrict
access for the lower rear panel connectors?  I can?t tell those detailed
dimensions from the pictorials . . . .   Any other reason not to do
something like that?

Ted, KN1CBR

I ran into this today too, different frequencies though. I recently
installed the KBPF3 module and have it enabled full time. I think what
happened is the VFO-A frequency sets the BPF segment to be used and with the
wide split, it's not the right one for the VFO-B TX frequency to use.
Therefore you don't get enough drive through to the amplifier stages. The K3
will not switch BPF segments to go between RX and TX states. I got an
ERR:TXG indicating something was afoul in the BPF setup. 

I tried to set the KBPF3 to 'not installed' but botched it since I didn't
remember you had to cycle K3 power to reconfigure that option. By then NSS
had faded into the noise. Oh well, got 'em on one band.

I saw a demo last night of the FlexRadio bandscope.  It showed the noise
well above, on the Y-axis, the bottom of the display, but the waterfall
didn't show the noise, just the signals on the band.  

 

When I set the REL LVL on my P3 so the noise floor is below the noise, the
waterfall is blue from the noise, making it difficult to see the signals.

 

Can someone enlighten me as to why the displays are so different?

after 4 years - took a lot of looking to see it in the first place.  I'm not
all that sad, because the way it operated, the outside of the coax shield
was the counterpoise, bringing RF into the radio room that locked up my

With that said -- I am considering an Alex-Loop which will meet the
aesthetic requirements of the Patrol Harridan (who fortunately is
"overlooking" the 3 J-Poles) but it is impossible for me to install the loop

there any solution for a remote tuner?  Or haven't I looked far enough?

Hi Jim,

They may be automatically calculating a long-term-average noise floor, then
subtracting it from the waterfall. The P3 could do the same thing. But
automatic noise subtraction would have the same disadvantage as slow AGC: a
temporary rise in the noise floor would mask weak signals for the duration
of the averaging time constant.

You can achieve the same thing manually, without the averaging issue. Simply
adjust the REF level such that the noise floor is just at or slightly below
the line. The waterfall will then be nearly invisible except for signals and
higher noise peaks.

Look at the W4OP loop.  The W4OP offers manual and remote tuning options.  I
have the W4OP (with manual and remote tuning units) and the AlexLoop The
W4OP is the one that gets used the most, although it?s a bit heavier when
packed and can?t really be hand held.  Both are nice products.

Hi Phil,
I use a cordless phone, or a cell phone, contact the second phone, and tune
my loop from about 100 feet for most noise.  Once you get the hang of it,
you can hit a 1:1 almost every time...

I have a homebrew Alex Loop running now, outside, and doing WSPR.  Go to
WSPR net, and select NK7Z, then look at the last few hours...  I got all
sorts of DX yesterday, which you can see by looking at the last 12 hours...

If all of that fails, I will be constructing a 12 foot loop for 40, and
building a remote tuning device out of a servo and an airplane controller.
I can share with you what I end yup with if you want.

73s and thanks,
Dave

I'm not all that familiar with the Flex stuff but in some SDR software
display systems it is possible to adjust the waterfall sensitivity and
contrast independent of any spectrum bandscope position adjustment. It is
often also possible to have any signal levels indicated by such displays
bear no relationship to any accurate level.The P3 waterfall contrast changes
with the reference level setting which in itself changes with the displayed
bandwidth, seems appropriate. Scale will adjust the sensitivity I think.

In the situation I have here where it is unusual to have any signals on any
band at more than S7-8, nearest centre of any appreciable activity is
several thousand miles away so mostly fairly weak signals, in this case I
find having the waterfall in monochrome, spectrum display is still in
colour, to be quite an advantage. It is quite possible to set an almost
black waterfall with signals barely above the noise floor showing as grey
marks, often much more discernible than anything on the spectrum display.

Hi Martin,

I have a somewhat different solution to your problem, and it consists of
multiple parts.

First, I set averaging to maximum (I set it years ago, don't ask me
numbers). :)

Second, I set Scale to 24 dB when I'm not contesting, 32 dB for 100W
contests, 42 dB for high power contests.

Third, I set reference level so that the noise level as at the bottom of the
amplitude display , which causes the waterfall to be black where there are
no signals.

Fourth, I set Tracking Mode ON, so that when I tune, the signals on the band
stay put as I tune across them. Without this setting, Averaging would reset
every time the changes frequency.

A major benefit of averaging is that it causes random noise to cancel itself
out, leaving only signals (and noise that is NOT random). Now, both the
amplitude display and the waterfall will show only real signals plus noise
that's more or less stable in frequency, like clocks from microprocessors,
and "lumps" of noise which may drift a little or a lot. 
Those lumps are generated by power-handling devices like switch-mode power
supplies and variable-speed motor controllers.

I don't use monochrome display, but I do see signals against a nearly black
background.

I can't replicate this problem with the KBPF3 installed in the Sub Rx
instead of the main.  CONFIG:KBPF3 says "Not Inst", for main, "Sub Nor"
when I tap SUB.

If you have the KRX3 Sub Receiver installed, a possible workaround is to
operate with SPLIT *OFF*, SUB ON.  Now you're transmitting on A, listening
on both.

Try putting VFO A on 10.115 and listen with VFO B (SUB) on 9.448.  Perhaps
RX on Sub will be attenuated.  Tapping B-SET + Pre-Amp may help bring some
sensitivity back.

If you want to listen to VFO B with both ears, set *CONFIG:L-MIX-R* to *b
b*.

Don,

I suggest you need to draw attention in your web page and general advice on
here to the requirement to choose the AUDIO FREQUENCY with some care when
setting up ALC for FT8 via the TUNE button in WSJT-X.

The problem seems to be that the DSP sampling rate inside the K3 must not be
related to the TUNE frequency. Ideally I expect they should be co-prime, or
something like that, to avoid aliasing artifacts in the ALC bargraph
readout. The actual frequency you should choose is probably affected by PC
and K3 clock frequency accuracy becasue a change of just a few Hertz can
have a dramatic effect.

In my case, the default WSJT-X tune frequency of 1000Hz is about as bad as
you can get. My ALC bargraph oscillates with a beat frequency of not much
more than 1Hz. And the ALC goes from zero to 6 bars! What is really
confusing is that WSJT-X leaves the tune frequency at whatever it was when
you last transmitted, so if you tune around, click on some signals, have a
listen and then try using TUNE the audio frequency could be anywhere unless
you take specific action.

Now that I see what is happening the solution is simple and obvious. If the
ALC bargraph is unstable then move the TX frequency 10Hz and it should
become sane. Only then can you go through the procedure you describe to set
the PC output level, WSJT-X power level and LINE level for the magical 4
solid plus one flickering bar.

Of course, once you begin making FT8 QSOs and move transmit audio frequency
it is entirely possible you will hit on a "bad" interaction with the K3 DSP
and the ALC bargraph will be all over the place again. As far as I can see
with an external power meter this ALC anomaly does not affect the
transmitted signal, but I've not looked into this in detail.

Carl, I suspect that the issue you see is not a KPA1500 issue.  The same sequence takes place the first time you use the KPA500 each day.  In fact I have seen the same issue with the K3s by itself with no amplifier.  It takes mine a few words or short sentences to ramp up to whatever the K3s power has been set for.  CW dits will start the process but it seems to take SSB voice to complete it.

After the power ramps up (a few seconds of ssb modulation) it will stay at that power level until the K#s has been powered down and turned back on.  This is what I see on mine anyway as does another local K3s/KPA500 user.

It will happen EVERY TIME the k3s is first started for both of us.  I believe we both have the mic and compression settings correctly adjusted but low mic levels or low compression will lengthen the duration of ssb modulation required to stabilize the output power.

I have seen this described several times on the reflector without having seen any explanation for why it might occur other than the method Elecraft uses for power control.

I hear you. In the case I described, the power NEVER comes up on SSB until I switch to CW and back to USB. Annoying.

 Sounds like an ALC issue. Do you have CONFIG:EXT ALC OFF?

Also, do you have CONFIG:TUN PWR set to NOR or to a fixed low level?
Instead of switching to CW, what happens if you press OPER on the AMP, then
press (hold) the TUNE button on the K3?  Then immediately try the mic?

Try setting CONFIG:EXT ALC to OFF and CONFIG:TUN PWR to NOR.  Then power
the K3 OFF and ON using the power button on the radio to ensure that these
settings are actually saved (removing power by switching off power at the
power supply does not give the K3 a chance to save its current state or all
settings).

"What is really confusing is that WSJT-X leaves the tune frequency at whatever it was when you last transmitted, so if you tune around, click on some signals, have a listen and then try using TUNE the audio frequency could be anywhere unless you take specific action."


Nothing to get confused about. The tune audio frequency is always the frequency marked by the TX cursor on WideGraph and indicated in the TX frequency box of Main. Much earlier versions of WSJT-X had a bug which caused the tune frequency to be random but, to the best of my knowledge, that was fixed long before FT8 mode was introduced.


If you don't want the TX frequency to change, simply click "Hold Tx Freq".


I can't comment on the K3 reaction to FT8 tune frequency. My TS-590S has no such issue.

Alan,

That is getting into issues associated with WSJT-X and FT8.
My website article is written to apply to all soundcard data modes and 
not FT8 specifically.  There was no intention for addressing all the 
various data modes that could be used.  All of them require the right 
amount of audio drive.

You should look to the FT8 forums for questions about that aliasing.  If 
it were a K3 problem, that aliasing would also be happening with other 
data modes as well.
Other soundcard data modes do not have a problem with a TUNE at 1000 Hz, 
so why is FT8 any different?

Of course, if your soundcard is generating harmonics or significant IMD 
before it reaches the K3, there is not much one can do other than 
getting a different soundcard.

I don't know about the "moving 10kHz" thing, but I have heard reports of 
similar symptoms.

I should have said that this explanation is only valid with WSJT-X split mode is not in use.   When split mode is used the situation is either simpler or more complex depending on your perspective.


In WSJT-X split mode the audio frequency is constrained to the range 1500-2000 Hz.   If the TX cursor is outside the range 1500-2000 on Widegraph then the TX VFO frequency is incremented or decremented in 500 Hz steps such that audio frequency remains in the range 1500-2000 Hz.

Hi Wayne, 


The MARS to ham band K3 cross-band problem affects every band, 
but it was extremely severe on 30 meters because the NSS assigned 
frequency -- 9448 kHz -- was almost 700 kHz from our typical 
10128 kHz receiving frequency. 


Since switching between the K3 bandpass filters and the KBPF3 
band pass filters at T/R rates isn't a workable solution, how about 
this external BNC cable solution since my K3 transceivers have 
KRX3 sub receivers? 


If I understand the K3 internal receiver antenna switching correctly 
a single external BNC jumper cable allows the K3 to transmit and 
receive on VFO A on MARS frequencies and listen to any amateur 
band on the sub receiver: 


- Connect the RX ANT OUT connector to the RX ANT IN connector 


- Tap the main RX ANT button which connects ANT 1 to the RX ANT OUT 
connector and switches the input of the main receiver to the RX ANT IN 
connector (connected by the external BNC cable to RX ANT OUT) 


- Tap SUB to turn the sub receiver on 


- Hold BSET and tap ANT to set the sub receiver input to MAIN. This 
allows the subreceiver to listen on the RX ANT connected to the main 
receiver. 


I'm sorry I didn't think of this yesterday... 


tks

I have to admit, operating SPLIT between a ham band and a MARS band that falls outside the nearest ham-band filter isn?t something that occurred to me when writing the firmware. But I can change the filter selection algorithm to accommodate this case as long as a KBPF3 module is installed. 

Technical details: 

Since the K3/K3S is a downconversion superhet, we use very narrow ham-band filters. One of the narrowest is the 30 meter filter. 

To preserve the rig?s exceptional dynamic range, we switch the band pass filters with relays, not diodes. This means we can?t switch filters at T/R rates. 

So to handle the case being discussed, we?d have to select the 7-10 MHz KBPF3 filter for both RX and TX.

Frank,

You still have the K3 Low Pass Filters to deal with.
The KBPF3 in the sub and the use of a separate RX antenna may produce 
better results.

But then Wayne is the guy to say what other obstacles might be in the way.

Hi Don, 


Fortunately I have a year to implement a solution! If worse comes 
to a worse, I could use a small external T/R relay to switch the 
antenna between K3 ANT1 and the KRX3 sub receiver AUX input... 



Is any publicly available performance data available for the low 
pass and bandpass filters in the K3 and the KBPF3? 


Its hard to devise a solution without this knowledge! 


Thanks for your help!

Frank,

It's also hard to suggest a solution without a clear understanding of the
problem, which seems different than N3CW's original question.

It's not clear to me what you need to achieve at NSS.  I think you are
saying you want listen to *both* widely-separated frequencies at the same
time, using different antennas, one for the MAIN, one for the SUB?  Or
maybe you want to use the TX antenna for both receivers?  Or maybe a
separate RX antenna for both receivers?

The SUB listens to either what is selected by MAIN (RX ANT or TX ANT) or to
AUX, which is a totally separate RX ANT input that seems to bypass all the
filters in the MAIN.  With the SUB on, hold RX ANT to switch the SubRx to
listen on AUX.  This is a perfect input if your RX antenna is miles away
from your TX antenna, which I assume is the case at NSS.

Otherwise, if you want to listen to the TX ANT with both receivers, feed RX
ANT OUT to *both* RX ANT IN *and* to AUX via an external 50 ohm splitter
such as the Mini-Circuits ZFSC-2-6
<https://www.minicircuits.com/pdfs/ZFSC-2-6%2B.pdf>, and now both receivers
are listening to the same antenna, but with totally different receive paths.

If you want to listen to a dedicated well-separated RX antenna in both
receivers, instead of listening on the TX antenna, use an external splitter
to feed the RX antenna to both RX ANT IN and to AUX.

Repeating, do not use SPLIT mode, just tap SUB to TX on A, receive on both
A and B, or just receive on B (CONFIG:L-MIX-R B B), whatever you require.

73,
Bob, N6TV

Good Evening,

 ??? For some odd reason I had the high temperature of the day at 87 
degrees.? The bands were still weak but the noise was less than last

top three.

During these lulls in the sunspot cycle having a quiet spot is the only 
thing you can hope for.? Occasionally a strong signal pops up but the 
QSB keeps comments shorter.? A few more years and the sun should be more 
responsive to our needs.? Until then I'll keep practicing with my left 
hand.? It is growing stronger and learning the alphabet.? I had truly 
forgotten the code so each time I send with my left hand I have to 
remember how to send each character.? It is odd, I have to hear the code

In time for Field Day, or your next hike up the mountain, a Buddipole System!

For Sale in San Francisco Bay Area

Buddipole Deluxe Long System, including tripod, 18ft mast, two standard arms, rotating arm kit,
three telescopic (13-66?) whips, fifty feet coax with choke, three coil clips and padded travel bag.

Plus optional extras, including two additional standard arms (for total of four) three additional telescopic (13-66?) whips (for total of six), three additional coil clips (for total of six), mast guying kit, wire assembly, 6 Meter Yagi kit, six knurled base whip screws, and two long telescopic (21-114?) whips.

With original sales receipt from Pacificon purchase, all in $768, including tax.

Note guarantee/warranty covers failures due to manufacturing defects by original and subsequent owners, effectively transferable for these kind of defects.

Buddipole appears to be in mint condition. Assembled once, pieces fit like a watch. Much of the kit still in original wrapping. 

Thought I would use it outdoors as it was intended, but my creaking and mobility issues preclude use as it was intended. Hence it must go 

Asking $600; but will consider reasonable offers.

Happy to meet halfway around Northern California from my Marin QTH for personal delivery. Prefer not to leave such a great unit to the vagaries of FedEx or UPS or USPS.

Please contact me off the forum.
Pictures of the device available upon request to AG6CX1 at gee mail.

And Go Elecraft!

This is what I do. Then I read the noise level in dBm from the screen. Very useful to compare noise levels at different times, etc.

But what I would like is a menu command that could be assigned to one of the function keys to automatically compute the average noise level and then adjust the ref level.

There would have to be an adjustment for an offset from the average, so you could set it up once to look the way you like it.

Then you could just tap the key whenever you want to readjust the ref level, and it would alway look the same.

I had this same problem operating split while listening to 18.150 and transmitting on 16.298.5 the K3s would show zero output.  However operating split from 20 meters to 16.298.5 worked.  Yes I have the KBPF3,  The other freq?s we used split worked fine.

Hi Bob, 


Thanks, I'll try your ideas. We have a year to get ready for our next 
NSS operation... 



NSS was a Field Day style operation with AB-577 towers, all of the 
NSS towers and buildings were demolished 20 years ago except for 
three 600 foot towers that are all in the red zone of a firing range! 
Because its a Field Day style operation, we don't have enough time 
to install separate receiving antennas despite our 500+ acre NSS site... 


Our objective is to transmit on our assigned MARS frequencies outside 
the ham bands (e.g., 9448 kHz) and listen inside the adjacent ham band 
(e.g., 10128 kHz). We don't need to listen to both frequencies at the 
same time. 



Our K3 main receiver and KRX3 subreceiver share the same antenna 
and the transceivers have KBPF3 bandpass filters installed in the 
main receiver only . 



Before we began NSS operations on Saturday morning we had no idea 
that the K3 could not perform out of ham band split operations without 
using the KRX3 sub receiver. When we realized that our transmit 
power output was severely reduced by using wide split (e.g., 
9448 / 10128 kHz) we started to search for a solution... 


We were not successful using the K3 transceivers with a wide split 
so on those bands with wide splits (e;g., 9448/10128) we removed 
the K3 transceivers and substituted our old FT-1000MPs instead. 
They worked very well and were very easy to use. The K3 is far 
from easy to use in this application! 


As was suggested, operation of the K3 transceiver to meet our needs is 
much easier if we install a KBPF3 in each KRX3 subreceiver, since 
K3 operators almost always use their KRX3 sub receiver with SPLIT 
enabled, which forces the transmitter to transmit on the sub receive 
frequency. But a KRX3 sub receiver with no KBPF3 installed 
can't listen outside the ham bands where we transmit. So the 
commonly used SPLIT operation with the KRX3 can't meet our needs 
with our K3 transceivers with no KBPF3 installed in our KRX3 sub receivers 


If I had known not to tap SPLIT as I've always done when not transmitting 
on MARS frequencies, I may have been successful since we would then 
have been transmitting through the Main Receiver KBPF3 on the 
VFO A MARS frequency, and listening to the KRX3 sub receiver 
in the ham bands. 


I'll try split operation on 9448/10128 well before next year by not using 
SPLIT and listening on 10128 with the KRX3 sub receiver...

Frank, 



It's also hard to suggest a solution without a clear understanding of the problem, which seems different than N3CW's original question. 


It's not clear to me what you need to achieve at NSS. I think you are saying you want listen to both widely-separated frequencies at the same time, using different antennas, one for the MAIN, one for the SUB? Or maybe you want to use the TX antenna for both receivers? Or maybe a separate RX antenna for both receivers? 


The SUB listens to either what is selected by MAIN (RX ANT or TX ANT) or to AUX, which is a totally separate RX ANT input that seems to bypass all the filters in the MAIN. With the SUB on, hold RX ANT to switch the SubRx to listen on AUX. This is a perfect input if your RX antenna is miles away from your TX antenna, which I assume is the case at NSS. 


Otherwise, if you want to listen to the TX ANT with both receivers, feed RX ANT OUT to both RX ANT IN and to AUX via an external 50 ohm splitter such as the Mini-Circuits ZFSC-2-6 , and now both receivers are listening to the same antenna, but with totally different receive paths. 


If you want to listen to a dedicated well-separated RX antenna in both receivers, instead of listening on the TX antenna , use an external splitter to feed the RX antenna to both RX ANT IN and to AUX. 


Repeating, do not use SPLIT mode, just tap SUB to TX on A, receive on both A and B, or just receive on B (CONFIG:L-MIX-R B B), whatever you require.

Hi Wayne, 


The MARS to ham band K3 cross-band problem affects every band, 
but it was extremely severe on 30 meters because the NSS assigned 
frequency -- 9448 kHz -- was almost 700 kHz from our typical 
10128 kHz receiving frequency. 


Since switching between the K3 bandpass filters and the KBPF3 
band pass filters at T/R rates isn't a workable solution, how about 
this external BNC cable solution since my K3 transceivers have 
KRX3 sub receivers? 


If I understand the K3 internal receiver antenna switching correctly 
a single external BNC jumper cable allows the K3 to transmit and 
receive on VFO A on MARS frequencies and listen to any amateur 
band on the sub receiver: 


- Connect the RX ANT OUT connector to the RX ANT IN connector 


- Tap the main RX ANT button which connects ANT 1 to the RX ANT OUT 
connector and switches the input of the main receiver to the RX ANT IN 
connector (connected by the external BNC cable to RX ANT OUT) 


- Tap SUB to turn the sub receiver on 


- Hold BSET and tap ANT to set the sub receiver input to MAIN. This 
allows the subreceiver to listen on the RX ANT connected to the main 
receiver. 


I'm sorry I didn't think of this yesterday...

Don,

I'm puzzled you when you say

"If it were a K3 problem, that aliasing would also be happening with 
other  data modes as well. Other soundcard data modes do not have a 
problem with a TUNE at 1000 Hz"

I can reproduce this problem with my K3 with MMVARI on other data modes. 
I have tried it with another PC and sound card and again I can still see 
the problem. So I suspect that feeding a pure sine wave from any source 
into LINE IN can cause ALC bargraph artefacts at certain specific audio 
frequencies.

This is not FT8 specific, nor is it audio harmonics or IMD. It is simply 
an unfortunate choice of audio tone frequency interacting with the K3 
internals. Or at least that is my best guess from the evidence I see 
here. The only constant throughout these tests is my K3. If it is faulty 
then OK, no big deal.

I hoped by reporting this effect on this mailing list I might help the 
others who have also commented about it. If there is a consensus that 
it's specific to my setup then OK. I can reliably avoid my problem by 
changing the audio tone frequency just a few Hz so I will just do that 
and get on with my life.

Alan,

How high is the input level to the K3 Line IN?  I am wondering if you 
are driving the transformers in the audio in slightly into saturation.

Try lowering the soundcard output and increasing the LINE gain.

This problem has been reported in the past, and is known to be a K3 
problem.?? Just choose a slightly different? audio frequency
for the tune up.
 ??? It does show up with other sound card modes.
As far as I know ALL K3's have this "problem".
My K3 (sn 5540 or so, not at home and don't remember exactly) has had 
this problem since day one, and still does even with ALL upgrades 
installed, including the new synthesizer upgrade (KSYN3AUPG).

It's been about 2-1/2 years since I got back on HF and purchased the K3S and P3 at Foxboro from Eric. I just don't know what to say. In 58 years of playing radio I still smile every time I turn the rig on.


It has performed flawlessly and I am amazed (even as an EE) at the features it has. With just a fan dipole I have worked 230 / confirmed 220 and many is the time where I can clearly hear and work very weak signals  when no other east coast stations are calling them.


It just works. No problems, no issues other than there are no issues ?. Just  a great radio!

Thanks for this, Gordon. I failed to search properly and missed that 
previous thread. Elecraft ought to at least acknowledge and document the 
issue even if they don't fix it. I did some googling and I now see that 
this is a well known and widespread problem. It seems to have a well 
known set of solutions, discussed for example here

https://en.wikipedia.org/wiki/Dither

So it does seem fixable in principle but it will involve engineering and 
business trade-offs which only Elecraft themselves can address.

This has been very interesting and informative. Apparently once this
strange glitch is understood, one can easily work around it. Thanks to Alan

Hi all,

 

Just wanted to let you know that QRPworks will be at FDIM Thursday night and
at the same Hamvention booth as last year...booth 1611 which is in building
1, right across the aisle from Elecraft.

 

We'll have a few new goodies to look at..."SolMate", a solar charge
controller, and a prototype of "Stay Tuned", a VSWR / Power Meter with audio
output.  Great for tuning mag loops.

 

Hope you can stop by and say hi.

It's been about 2-1/2 years since I got back on HF and purchased the K3S and P3 at Foxboro from Eric. I just don't know what to say. In 58 years of playing radio I still smile every time I turn the rig on.


It has performed flawlessly and I am amazed (even as an EE) at the features it has. With just a fan dipole I have worked 230 / confirmed 220 and many is the time where I can clearly hear and work very weak signals  when no other east coast stations are calling them.


It just works. No problems, no issues other than there are no issues ?. Just  a great radio!

When transmitting SSBSC is the output from the DSP a SSBSC or DSBSC signal?

It is not clear to me if the crystal roofing filter removes the opposite sideband or just cleans up what is left of the opposite sideband coming out of the DSP when transmitting either LSB or USB.

Message-ID: <1526387207022-0.post@n2.nabble.com>

KX3BNCMDKT Upgraded BNC connector for KX3. (User installed)  Includes an
integral VHF/UHF filter to reduce the possibility of weak signal
interference to very close by VHF/UHF radios, HTs etc.  Not required for
normal KX3 operation. 

Hi all,

is there anybody who has experiences with this modification please?
I wonder how it looks like (some pics) and if it is necessary, helpful,
mandatory, "is a must" or what?

Thanks for info,

I was watching 6m yesterday and noticed several spurs. They were spaced 39kHz
apart. Amplitude dropped but didn't disappear when switched to dummy load.

I have the K3 with new synthesizer boards. Just wondering if anyone else seeing
something similar. IOW is it something in the K3 or external?

I purchased it as a replacement BNC connector for my KX3, as I had, through
testing, determined that my connector was bad.  (The hypothesis was that it
had a deformed center jack by another user using a 75-ohm BNC cable, but
that was not conclusively proven.)

It was an easy replacement (except for the struggle to put the ATU back in
- make sure you line up the connector pins) and the KX3 is now working FB
once again.

I have no experience in using that versus the regular BNC connector; that
was what was told to me as the replacement BNC going forward.

Petr,

The quickest way to see it is to download the newest KX3 Assembly Manual 
and look starting on page 24 and going through page 29.

I don't know where your antenna is located, how your feedline runs, or 
where your dummy load is located, but....

You have some kind of switch mode power supply or similar device that is 
coupling with your antenna and/or feedline.

That the signal dissipates some when on the dummy load is a clue to 
where the source might be...

I'd be almost positive it is external to the K3...

Are you powering the K3 with a SM power supply?

I've seen a K3 generate spurs when the power supply was overloaded, and 
went into current limit.

Hi guys,

thanks for info. 
Unfortunately in the manual is no more information about the LPF itself,
just how to install it.
In all cases I have at least an idea what it is...

Subject: [Elecraft] K3-0-mini / K3 dilemma
Message-ID: <c10cb7f9-cdf3-0cad-5b23-642f097c1be8@jpcummins.net>

I have been working with a retired doctor ham friend of mine who has 
moved into an assisted living facility.? He has been licensed and active 
for more than 40 years.

He wanted to be able to use his K3 remotely and I had helped another 
friend of mine who is blind and is also a long time active ham get back 
on the air from a condo using the Kenwood TS480SAT -Remoterig RRC1258set 
implementation. This approach has worked for nearly 2 years without a 
hitch.

I suggested to my doctor friend that we should test whether it would be 
possible to operate remotely from within the large facility where he 
lived.? So we met with the IT staff there and they had no issues and 
showed that his apartment had internet already installed. Before we 
ordered any equipment I borrowed the TS450SAT control head and Remoterig 
RRC1258-control and tested from his apartment at the assisted living 
facility and it worked perfectly.

On the strength of the testing we ordered the K3-0-mini/K3 Twin package 
from Elecraft.? After getting over the shorted cable that goes to the 
ACC jack on the K3 and a dead power supply for the mini I successfully 
tested on my LAN and also from several other remote locations.? We then 
unsuccessfully attempted to operate from the assisted living facility.

For more than a month now we have been communicating with Microbit and 
Elecraft K3 support trying to figure out what the problem is.? 
Additional tests with the TS-450SAT continue to operate perfectly from 
the facility and testing the K3-0-mini from several other sites out side 
of the assisted living facility also work perfectly.

Working with the IT staff at the facility we are convinced that there is 
a difference in the packets being generated by the Elecraft and the 
Kenwood but I have not been able find any documentation to help identify 
that difference.? We feel certain that the internet server at the 
facility is finding something suspicious in the Elecraft packets that 
are not present in the Kenwood packets.

Has anyone else run across something like this?

I'm just spitballing here, but could the net connection there be double
NATted so that the rig can't see the packets returning (since they have a
different address?)

Packets are packets.  I had this problem - loss of connectivity - albeit
with a media server in my house that I wanted to be able to hook to
remotely.   I called my ISP who pinky swore that they were not double
NATting the address.  I did some digging and logged into my cable modem and
sure enough, NAT was turned on (which meant there was one translation in my
router, and one more in the modem.)  Double NAT. Turned it off in the modem
and bingo, the server was visible to the world.

I'm hesitant to tender this solution, mindful of the old saw that "if the
only tool you have is a hammer, every job looks like a nail."   But at
least it's something you can eliminate and it might be good for thought.

Another idea is to check the port settings on the router to ensure the port that Elecraft is using is ?open?.

Not knowing much about the protocol Elecraft / Microbit uses, or the IT
staff at the facility, I have doubts about what is being done to figure out
what the problem is. There are tools, such as Wireshark to look at the
packets as they flow through or don't flow through the network. You don't
have to guess. It is likely that some firewall is blocking the packets,
either outgoing or returning. Firewall rules may need to be set up or
changed. Microbit looks like it requires port forwarding for ports
13000-13002 and that must be done in any routers in the way. If they are
doing double NAT on two routers, both will have to get port forwarding set
up. A good IT person should be able to figure this out with the right tools.

All that being said, I don't like port forwarding. I created an incoming
VPN that can be connected to from outside my network using OpenVPN. There
are issues with various firewalls letting the VPN through but if they
connect, the remote device looks like it is on the local network and
everything works, and is encrypted end to end. That is not easy to set up
though.

The LPF is a tiny toroid and a capacitor attached directly to the back side of the BNC jack. That is all.

Unplug the cable, remove the jack, mount the new jack, plug in the cable. Remove and replace any boards that are in the way.

Ideally... actually definitely need the one with the external DC power

The KPA500 provides the ^WS; serial interface interrogation which returns output power and SWR.  The power and SWR are reported for STBY and OPER modes.   In OPER mode the power seems to have a resolution of 1 Watt.  In STBY, if I increment my drive power in 1 Watt steps the power reported by ^WS;  jumps from 30 to 40 with no intermediate steps.


WS pwr  LP100 pwr

00            24.9

10            25.8

25            29.4

40            40.3


Is this very low resolution of WS power in STBY mode intentional? (firmware 1.54).

 If you have an older K3 there was a problem with them generating a spur.? I had the problem when a friend reported hearing me on a 2nd freq.I'm guessing nobody still has an older K3 though with this problem.
We have determined that a small number of K3/100s and KPA3s left the factory earlier this year (2009) with capacitor C3 installed by mistake on early Revision C KPA3 PC boards. ?This part location should be empty on Rev. C KPA3s. ?Installation of C3 causes the PA bias supply to oscillate on some KPA3s at approximately 15-20 kHz, resulting in spurious TX sidebands at that spacing from the carrier.
Info is on the Mods & Notes page almost at the bottom.?

 I was watching 6m yesterday and noticed several spurs. They were spaced 39kHz
apart. Amplitude dropped but didn't disappear when switched to dummy load.

I have the K3 with new synthesizer boards. Just wondering if anyone else seeing
something similar. IOW is it something in the K3 or external?

 After having played with mine extensively last night, I was under the impression that the fans would come on automatically when the temp reached a certain degree.That is not the case.? Mine was defaulted at fan speed zero, which is fans off.? You have to change the menu item for fans to one of your liking.? I had read a few postshere on the reflector about 2 being an acceptable number.? I agree.
If you crank it up to max (5) you might scare the dog, be careful, hi.

 ALC is adjustable but it is recommended to just set your per band drive level for desired output.? You can set the ALC thresholds fairly high to not allow ALC to affect 
your output unless under extreme condx.

 This may have been discussed already, but just wanted to confirm.

I had a number of questions, but I'll condense them into a few:? 

How are the KPA-1500 power LEDs/display calibrated at the factory, and what equipment is used to do the calibration?

Second, in the case of using the amp with K3 and the KPAK3AUX cable, is there a point where ALC kicks in and decreases power output?

Thank you!

When your topline rig are is at or near the top of Rob Sherwood's list 
of the best receivers and of the cleanest CW transmitters tested by 
ARRL, and your super-portable rigs give most desktop rigs a run for 
their money on performance, and when you've got first-rate power amps at 
the 100w, 500W, and 1,500W level, it's hard to justify the argument for 
a new transceiver.

I consider the K3S to be what Gordon Bell called a ?mid-life kicker?. That is a technology upgrade with small changes to the design. It extends the life of a product without the cost of a major redesign. It can be a very smart move.

For example, the VAX-11/785 was the same as the VAX-11/780, but built with a faster logic family so it was 50% faster. That is a pure example?a DEC spokesman called it ?bug for bug compatible?. 

This is the section on ?mid-life kickers? from a long chapter by Bell, Mudge, and McNamara about technology and product strategy.

https://books.google.com/books?id=SDOoBQAAQBAJ&pg=PA62&lpg=PA62&dq=gordon+bell+mid-life+kicker&source=bl&ots=qrJ7DM7xPt&sig=YZyqZTRujNvDkGTgPQffOUv2UBo&hl=en&sa=X&ved=2ahUKEwjI6fGJkJDbAhWHO48KHVSyCWUQ6AEwAHoECAEQKg#v=onepage&q=gordon%20bell%20mid-life%20kicker&f=false

And of course, you stay on top by obsoleting your own stuff before your competitors do that.

Bill, default setting is fan "0" -- then they remain off until needed as amp 
heats up with use. All automatically. So you hear no noise while you're just 
listening to receiver, etc.

Roy    K6XK    Iowa

After having played with mine extensively last night, I was under the 
impression that the fans would come on automatically when the temp reached a 
certain degree.That is not the case.  Mine was defaulted at fan speed zero, 
which is fans off.  You have to change the menu item for fans to one of your 
liking.  I had read a few postshere on the reflector about 2 being an 
acceptable number.  I agree.
If you crank it up to max (5) you might scare the dog, be careful, hi.

Bill,

My KPA1500 also defaulted to FAN SPEED MIN = 0, but that is not fans off 
(at least not on my amplifier).

My fans engage at 60c (low), 65c (medium) and 70c (egads).

Is there a menu explanation somewhere about the start/stop temps and 
speeds? I would like a little more hysteresis in the 60c setting: start 
at 60c but continue cooling until temp drops to 50c. That might work a 
little better when running digital modes with long Tx/Rx intervals.

What features would your K4 have?

In mine, it would be satellite-ready:  full duplex, 2 & 435.  Interfaceable to common satellite programs.

Compared to the K3S:

RX maximum audio bandwidth increased from 4 kHz to 6 kHz.

More macro buttons.

Higher resolution S-meter (more bargraph segments).

1/4" jacks instead of 3.5mm ones.

Longer&fatter 13.8V power cable

24-bit digital audio i/o, without going D-A-D.

Steeper filter slopes on SSB TX passband to widen audio while staying
within 3 kHz occupied bandwidth (cf IC7300).

The KPA500 provides the ^WS; serial interface interrogation which returns output power and SWR.  The power and SWR are reported for STBY and OPER modes.   In OPER mode the power seems to have a resolution of 1 Watt.  In STBY, if I increment my drive power in 1 Watt steps the power reported by ^WS;  jumps from 30 to 40 with no intermediate steps.


WS pwr  LP100 pwr

Is this very low resolution of WS power in STBY mode intentional? (firmware 1.54).

Why?? It's a ham transceiver.? If you want a "short wave" RX to listen 
to broadcast, buy an inexpensive SDR that plugs into your USB port and 
have any bandwidth you like! 
https://www.rtl-sdr.com/roundup-software-defined-radios/

I own both an SDRPlay RSP1A? ($99) and a FunCube Dongle Pro+ ($210). I 
bought them for chasing RFI, but they work very well as receivers.? Many 
great (and free) choices of SDR software, including this by Simon Brown, 
G4ELI.

> More macro buttons.

Can't argue with that, but the radio would need to be bigger.? Have you 
studied the manual for the many ways to save presets of frequency, mode, 
etc. ?? Lots of things we want to assign to macros can be solved that way.

Why is that important?

> 1/4" jacks instead of 3.5mm ones.

Why?? Quality of jacks and plugs?? Simply buy good quality plugs 
(Neutrik and Switchcraft are the good brands) and make your own cables.? 
And if you want those bigger jacks, the radio would have to be larger.

> Longer&fatter 13.8V power cable

Buy a Power Pole connector pair, buy the size of cable you want, pull 
out your soldering iron and make any power cable you want.

Buy and plug in a 8-pole 2.8 kHz roofing filter to replace the 2.7 kHz 
filter. If you can tell the difference between that and 3 kHz bandwidth 
you've got better ears than me. Further, any audio content below about 
400 Hz is wasted in a communications circuit.

Yes a new K4 with integrated pan adapter would be cool. But I would not
expect one anytime soon. The K3S is not going be out done in the near
future. What I would like to see is a 30-watt portable rig. When 5 watts is
not enough, 30 watts often is as good as 100 watts. A small 30 watt rig
would be easier to carry then a KX3 and amp or a K3S. Kind of like the old
SGC 2020.  I run my 100-watt rig at 25 watts in the field and it works well
and conserves the battery.  I think there is a void in the market currently
for that type of rig. Elecraft could knock it out of the park if they built
one. All of us have a K3, KX3, KX2 that want one. But none of us have what
I just described.

Hi Ed,

FWIW, I regularly copied JT9 signals up to at least 3 kHz; remember 
that, in those days, JT9 typically started around 2 kHz baseband, and it 
is possible to open up the RX IF bandwidth wider than that 2.8 kHz 
roofing filter.

And although the worm will hopefully turn back in favor of JT65/JT9 on 
160M, those modes have virtually disappeared since FT8 was introduced. 
Last season, you, W6GJB, and I all worked SM6 on JT65, and WSJT-X 
decoder logged several dozen EU stations. This year, I hear east coast 
stations working (or at least calling) EU, but I've decoded ZERO EU 
using FT8. (For those reading the mail, all three of us are within about 
20 miles of each other, 70 miles S of San Francisco. What I'd love to 
see is JT9 take over on 160M. If I'm not mistaken, it's good about 10 dB 
deeper into the noise than FT8.

And while it's true that any of the slow WSJT modes would benefit from 
greater IF and audio bandwidth by providing space for more stations, few 
other rigs offer that.

Frank -

The K3 is a top quality radio as is. The "must have" improvement 
is the new synthesizer, the KSYN3A Synthesizer Upgrade. It will 
improve your ability to hear the pileup while chasing DX. The 
improvement is noticeable in normal operation. It also improves 
CW operation, but my CW isn't good enough to play in those leagues.

I have also installed the KIO3B -- the internal sound card and 
USB <--> RS232, which reduces the number of cables in the shack 
and eliminates the external sound card for digital modes. I also 
have the KXV3B RX Ant., 2nd Pre-Amp which gives more gain in the 
pre-amp. I'm waiting for the sunspots to come back to the the 
maximum use from it, although I did get good value during a 6M 
opening New Years Eve.

I am happy with the upgrades I have.

 I can only give you a half a "duh".? The preliminary manual supplied with the amp only gives you the menu description of fan speed and it doesn't really describe the operation.The paragraph in the online manual labelled "Amplifier Cooling" is NOT in that preliminary manual.? The half a duh is for the first line of the menu description of "fan speed min".It says the speed varies per temp but after that sentence there is not much of a description.? It then says greater than zero all the way up to all fans running, leaving you in the dark.? It doesn't explain it like you or Roy explained it.
I really figured it would work like you explained but unless you read the online manual you are missing the amplifier cooling paragraph.? Thanks to you and Roy for clearing thisup for me.

Hello Frank,

As of recently I have both a K3 (without upgrades) and a K3S. The improvements which stick out for me are the improved CW timing of the new synthesizer at speeds above 32WPM or so, the easiness and ruggedness of the new internal soundcard when setting up digital modes, the selectable attenuation levels between 0 and 15db per band and, yes, the soft-touch VFO A grip. I have not seen the need to use preamp 2 but this may be because of my noisy environment causing S-meter action even on a dead 10m band. Others love it for weak-signal work.

While the new attenuator is not available as an upgrade most other things are. It boils down to your personal needs. If you have been happy with the rig as it is then there is little reason to upgrade. Personally I had given up on the K3 early on because of the CW timing issues which are explained in great detail by N6TV (see links). Now, the K3S is my preferred CW rig.

http://lists.f5mzn.org/pipermail/support/2013-November/083384.html
http://mldxcc.org/n6tv-k3.pdf

You may consider selling your K3 as it is (maybe saving the roofing filters) and get a used K3S depending on prices on the second-hand market.

Now that Eric is at the Hamvention we can not annoy him too much with mail overflow on this list ;-)

- I would like to see Elecraft revising the NR-function. While you can achieve nearly infinite noise attenuation with the K3?s NR it comes at the cost of signal intelligibility. At least I have failed to hit a setting for CW which works for me. The NR also seems to be dependent on AGC settings. With the IC7851?s NR at ca. 9 o?clock the band noise is cut about in half without affecting signals, even when they are weak. I do not miss this much in everyday operation. But the additional band noise really hurts in my ears when doing SO2R causing fatigue and ultimately increased error rate.

- I continue to be impressed by ICOM?s APF function. Combined with a few dB of additional amplification in the APF level menu this sort of has become a great ?panic button? for me when a weak station calls or QRM shows up. Elecrafts APF is way too sharp for this purpose. Maybe another APF with wider bandwidth could be added?

- It might also be helpful to add a simplified NB-menu which selects among some of your favourite settings. If you are forced to dig into the NB-menu in the middle of the heat the DX will long be gone until you have found the right setting to get rid of noise.

- Elecraft should consider adding mouse support for the panadapter.

- Coming from ICOM rigs I noticed that the knob resolution seems slow. This sticks out with the filter, RIT and power knobs. Too much knob spinning required for my taste. However, this may be subjective and there are work-arounds.

- I would also like to see Elecraft using higher quality buttons which are more responsive. When the K3 came out one of the reasons I never got one was the wobbling feel of the A/B (and other) knobs. It simply was not compatible with my style of operation which involves constantly switching VFOs when S&P. Yes, there are work-arounds, too.


I just realize that most of it may be another software upgrade. No K4 required!

Last season, you, W6GJB, and I all worked SM6 on JT65, and WSJT-X decoder logged several dozen EU stations. This year, I hear east coast stations working (or at least calling) EU, but I've decoded ZERO EU using FT8. (For those reading the mail, all three of us are within about 20 miles of each other, 70 miles S of San Francisco. What I'd love to see is JT9 take over on 160M.

Absolutely not true.  All it takes is the KFL3B-FM of KFL3A-6K filter.
I regularly decode the entire 4 KHz combined JT65/JT9 segment or more
than 3 KHz of FT8 activity.

To be able to decode multiple digital signals at once. Also to diagnose
intruder signals. And yes, occasionally, to listen to AM broadcasts,
without having to buy something else as well when I've just drained my
bank account to buy a K4! There's no inherent reason why this needs to
compromise the performance as a purely ham rig - it just makes it more
useful for one or two other things as well.

Yes thank you. Bigger isn't a problem for me. If it is for you, don't
buy a K4, stick to the K3(S)!

Because it's often useful to be able to see small changes in signal
level, which you can't do at 5-6 dB per segment. For example when
rotating an antenna.

I always buy Neutrik if I can, but IMHO there is no such thing as a good
quality 3.5mm jack plug. They are just too small and flimsy.

Obviously, but if I'm buying a K4 it would nice to have a cable in the
box that is long enough to reach from the rig to the PSU.

To get the same dynamic range on the audio I/O that already exists on
the 15 kHz IF. I'd like to be able to examine received signals using an
audio spectrum analyser with the maximum available dynamic range.

I already have the 2.8 kHz filter, and I'm more interested in the slope
at the top end than the bottom. Some other rigs seem to do better by
doing the slope in DSP and using the roofing filter for just that -
roofing. (The 6 kHz filter, if fitted, could be used here.) As for
content below 400 Hz, you're right for DXing, but if you're trying to
have a normal conversation it's much nicer if it goes somewhat lower.

That means you've enabled the ATU but it deems SWR low enough (settable)
that Bypass is the appropriate setting.

WSJT-X very elegantly uses split to offset the TX VFO an adjust
the transmit audio tone (subcarrier) to keep the tone frequency
between 1500 - 2000 Hz throughout the entire 4 KHz receive pass-
band.  There is no need (or justification) for a wider transmit
bandwidth.

Sold my 5000 to buy this and glad I did.. best CW rig ever..I would be happy with a loaded K3!! Do not want to be like Icom and come out with a new rig every year..

You are right on target!

I am curious about the 7300, but am unwilling to buy one, as I know it 
will just sit gathering dust. I know which side of my bread is buttered!

My real back up rig is a brand new K3S, sitting on a shelf at the 
factory. It will be shipped overnight to me when it is needed.

Even Rob Sherwood says his list isn't the only way to evaluate radios. And the 
last time I checked, he uses ICOM.

There is a market for a "K4" although Elecraft will deny that one is being 
designed, no doubt.? They said the same about a higher power amp, remember?? Now 
they are shipping KPA1500s.

A desktop radio would have room for some desperately needed ergonomic 
improvements. A tuning knob that doesn't rely on a felt washer to set dial drag 
for example. Fifty-volt finals that have decent TX IMD performance unlike the 
current abysmal IMD. This is a pet peeve of mine.? What good would it do to brag 
about RX third-order IMD performance if all of the signals on the band were from 
other K3(S)?

I have a whole list; when Elecraft is ready for me to beta test a K, I'm available.

I bought an RSP2 Pro from HRO.? At my location it folded up like a cheap 
suitcase from BC overload.? The internal BC filter was useless.? To their 
credit, HRO took it back.

Since Elecraft sells an "all band" filter, which I have in my K3S, why wouldn't 
it be reasonable to think of it as a "short-wave" radio?

I have both.? I haven't even upgraded the synthesizer in the K3,? which by 
general consensus is a must do.

The old K3 is deaf on 6 and 10 meters, if that matters to you.

The USB and internal sound card are nice in the K3S, but my serial-to-USB 
adapter worked fine and the shack computer sound card was as good on RTTY as 
some highly recommended external boxes like Tascam.? I also had less grief 
getting levels set with the old system.

I actually preferred the old tuning knob. I was able to glue in a larger felt 
washer in the knob and run it against the slick bezel and get reasonably good 
feel out of a primitive system.? The "soft-touch" knob and textured bezel are 
not amenable to this.

Personally, I don't think you're missing anything, but I'm sure the faithful 
will have other ideas.

I'll weigh in on this a little before it gets stamped on again as being, 
unfortunately, irrelevant and pointless.

I think there is a big gaping hole in the Elecraft product line. Not in 
performance terms but more in ergonomics. A K3 has been my primary radio 
for a few years now and before that an Orion, before that a TS940, 
TS830- etc etc. Performance wise there is no doubt the K3 bests them 
all, I recently built a K2 and think that's scarily good in raw 
performance terms as well. My K3 is pretty much fully kitted out and I 
have a P3 as well which is extremely useful and they're going nowhere.

 From the super small super portable super capable K2 and KX3 to the 
small and portable and no less capable K3/K3S their market segments are 
well covered but KenYaeCom have surely sold enough 
TS990,FT9000,IC7800/50/51 that shows well the market demand for a 
quality high end desktop sized radio. If the pictures on QRZ are 
anything to go by not everyone operates out of a shoe box with many 
having dedicated rooms for their radio hobbies. If the shoe box is your 
limitation then the K3 is undoubtedly a superb choice but where space is 
less restricted a bit more in the way of panel acreage might well sway a 
lot more FT9000/TS900/IC78xx users I feel, not to mention those of us 
who just feel the K3 package is, for a desktop radio, just a bit too 
much of a compromise.

Key requirements on my end after considerable K3 usage. A better more up 
to date menu system that either removes or better, handles the myriad 
un-intuitive selections. There are a number of menu options which unless 
you have significant handbook familiarity lack explanation about 
additional keypad presses. There are even some for which software 
updates need to be consulted though that is a different matter. Some 
menu choices could well be better homed as front panel controls. The 
keypad is another area I find seriously lacking for a top end product. 
Again, great for the type of product it is but I find it lacking. Band 
keys, mode keys, a proper band stacking register, a better way to deal 
with the sub receiver settings, more, bigger and wider spaced control 
knobs, yes all of this needs panel space but that shouldn't really need 
to be a problem. It's possible the entire form factor could use a 
rethink, do we need a box 12 inches deep. Why not a front panel that is 
16 inches by 6 inches on a radio that is just 5 inches deep. Overall it 
would likely be a similar volume and contain just as much under the 
skin. The Orion was probably overkill with the amount of fresh air in 
every box, some careful plug in board stacking could have reduced the 
box depth by half whilst retaining the same front panel space. A good 
display with all info including the somewhat obligatory scope and 
waterfall properly integrated seems a no brainer today I guess, of 
course with a port for connection of 36 inch full 4k displays, ideally 
with different screen displays.

I like the PA options today 10 or 100 watts, not sure how many are sold 
as just 10 watt radios though. In a bigger box, something like the 7850, 
16x17x6, it should be possible to integrate the KPA500 allowing for a 
500 watt transceiver in one box.

Where space is a premium the integration of multiple controls carefully 
arranged for maximum apparent efficiency is obviously a good thing 
though I feel it can be overdone, the poor operability of the sub 
receiver is a case in point and I've had heat of the moment run ins with 
the mic gain compressor and monitor controls as well. Great when it 
works as you think of it, less so when you're acting more by feel and 
intuition doing 6 other things at once and get a mis-press.

Much of this is software, packaging and ergonomics/HMI, so far as the 
pure RF side is concerned it's clear that things are evolving still and 
it can't be long before pure wideband direct digital SDR becomes the 
mainstream.

It's hard to fault the K3 on so many levels, it's just such a great 
radio but it's by no means an unflawed or unlimited radio and there are 
areas of the ham radio business Elecraft are yet to tread.

Oh and I'd love them to do a 2-35Mhz 125 watt radio suitable for 
commercial use. So many opportunities where the options today are either 
VK mobiles or US mil spec but that really is another topic.

At least I have failed to hit a setting for CW which works for me. The NR also seems to be dependent on AGC settings. With the IC7851?s NR at ca. 9 o?clock the band noise is cut about in half without affecting signals, even when they are weak. I do not miss this much in everyday operation.

When the K3 came out one of the reasons I never got one was the wobbling feel of the A/B (and other) knobs.

Message-ID: <1014391867.3145996.1526748879699@mail.yahoo.com>

My experience is similar to Stefan's. In so2r I typically used k3 as the S and P radio (but only after getting the the DSP board swap change). I used Orion as the run radio (and before that, Omni VI).

Other than on-the-air experience with radio equipment (my own as well as at ny4a M/M), the guide for me vis-a-vis radio performance is in two texts: Solid State Design for the Radio Amateur (1977, Wes Hayward and Doug DeMaw) and Introduction to Radio Frequency Design (1982, Wes Hayward).? On the one hand, this dates me (ok, so I am 67 years old, but I am still here and every day counts)!? On the other hand, how long does it take to understand and use a given level of technological excellence (as noted in the two texts), say in a cw contest (answer: far longer than the next "best ever produced" radio)?  BTW, after reading the above texts it was easy to understand the superior performance of Ten-Tec Omni series of radios compared to imports. Ten-Tec radios had later-to-be-named "roofing filters."

I was using Orion (revolution in synthesizer performance), mainly, but with the introduction of the new Elecraft synthesizer, I had my 2008 K3 fitted with one (plus any other mod that Elecraft wanted to include while they had the radio) and I purchased another K3.? So since early 2015? (anyway, right before K3s was released), I have been so2r K3, with dynamic range and phase noise second to no other radio.  In short, a (late model) K3 with synthesizer board (or an updated early K3 like one of mine) is as good as K3s for my purpose.  This perception has come from on-the-air experience, guided by the above text, as well as integration of the so2r system.

In K3s, the second preamp is not needed on 10m; you may need the preamp on 6m.? I use K3 160m-10m, HF contest bands only.? Having the ability to disable the K3 preamp and/or put in 10 db of attenuation works fine 160m through 20m.? K3S has 10db more blocking (150db!), but 140 db of blocking in K3 is already remarkable in that 130 db is outstanding.? The digital mode change of K3s would be desirable by digital mode ops, I suspect. 

My so2r system, here and now, is far more integrated and functional compared to anything I have used in the past.  One reason I don't want to change anything is because everything works as I wish, for the first time (this also includes software, tr4w? preferred)!? Of course my purpose is defined by cw only, and not by all modes.

I can think of small changes in preferences only (tied to using other radios), or different ergonomics. But at this point in time I have been trained by the K3 radios.? When I see other radios offering "this or that" function or performance, my main thought is "you don't know me that well;" the main part of the equation is me and what I have learned over the years.

Excluding so2r cw challenges, then I would find other radios to be just as good as K3 and better is some specific way, or another, or certainly more "cutting edge" SDR (but for what purpose?).

 Hello Frank,
 
 As of recently I have both a K3 (without
 upgrades) and a K3S. The improvements which stick out for me
 are the improved CW timing of the new synthesizer at speeds
 above 32WPM or so, the easiness and ruggedness of the new
 internal soundcard when setting up digital modes, the
 selectable attenuation levels between 0 and 15db per band
 and, yes, the soft-touch VFO A grip. I have not seen the
 need to use preamp 2 but this may be because of my noisy
 environment causing S-meter action even on a dead 10m band.
 Others love it for weak-signal work.
 
 While the new attenuator is not available as an
 upgrade most other things are. It boils down to your
 personal needs. If you have been happy with the rig as it is
 then there is little reason to upgrade. Personally I had
 given up on the K3 early on because of the CW timing issues
 which are explained in great detail by N6TV (see links).
 Now, the K3S is my preferred CW rig.
 
 http://lists.f5mzn.org/pipermail/support/2013-November/083384.html
 http://mldxcc.org/n6tv-k3.pdf
 
 You may consider selling your
 K3 as it is (maybe saving the roofing filters) and get a
 used K3S depending on prices on the second-hand market.

Frank,

I opted to do a few updates:
New synth boards for both main and sub receiver
Mod to general coverage bw filter

I already have plenty USB/RS-232 conversion cables and prefer that 
line audio go to the computer via external soundcards.  USB I/F would 
require use of internal soundcard.

A brand new tailor-made four channel 192-KHz ADC/DAC is being 
designed/produced specifically for digital modes and will require 
baseband audio from a receiver.  It will interface the computer via 
USB.  I'm on the waiting list for it.

I already have PR6-10 so not needing it to be internal.  I like the 
bypass feature to connect a remote preamp.
I already have the EXREF and TCXO-03.

The rest are frills for my operating (non-HF).

Cost less than trading up.  If I were buying new, then definitely get 
the new radio.

Message-ID: <707918951.3069528.1526750251905@mail.yahoo.com>

The K2 is specified to operate on 10m only up to 28.8 MHz.  While contemplating possible future VHF rigs for a multi-operator multi-band environment, I have wondered about using a K2 as an IF for VHF transverters at around 29-29.4 MHz (to avoid interference with bands using 28 MHz IF).

Both of my K2s seem to operate (VFO synthesizer works) up to 30 MHz.  At 29.5 MHz the available transmit power (QRP) is starting to drop off and this is quite noticeable at 30 MHz.  The QRP PA efficiency drops off somewhat as well.  There are a few receive birdies on the 100 watt radio, but the QRP one is pretty quiet - nothing that should be noticeable under the extra noise coming from a transverter.  Turning the preamp on makes extra noise as it should (but it is after the bandpass filters so that doesn't mean a whole lot).  But it seems that it should work ok as long as I don't want more than 4-5 watts (most likely I'd use a K60XV), perhaps with a bit of bandpass filter tweaking.

Are there any caveats that I am unaware of?  Spurious emissions, perhaps?  Has anyone tried using their K2 above 29 MHz?

If you are used to working large rigs with lots of buttons, I can see how the K3/K3s might be an adjustment.

I have found the K3 controls to be natural and appropriate.  For most of my operation the buttons and dials I need to use in action are right at my fingertips.  Once set up correctly, I find little need to venture into the menu system on a day to day basis.  

Sure. It would be nice to have band and mode stacks.  But is it that big a deal, worth spending many thousands of dollars to change?  

We will gain nothing in performance with a bigger rig.  Already Elecraft outperforms ALL of the big boxes on the market, per Sherwood Engineering.

Here is an elegant and simple solution for the K4 that will satisfy the big box demand.  

Design a modular big front panel that simply plugs into the K3.  Design should be relatively easy because you don't have to change the K3s itself, just add a command and control interface for the larger front panel.  Can you use the accessory port or do you need more connections?  I don't know I am not an engineer.  Currently computer radio control programs work with a simple DB9 connection.  

Then give an option of mounting the K3s in a larger box.  That would have the added convenience of making it easier for us klutzes to be able to get into the rig to make changes such as adding filters.

So, you would have options:
1. standard K3s
2. Standalone large front panel.  Put your K3s under the table and mount your front panel wherever.
3. K3s in a larger box with the larger front panel mounted on the front.  You can even add options to the large box such as nicer stereo built in speakers, even a built in AC to DC power supply.

It will all still be the best HF radio in the world, made right here in the US.

TS830- etc etc. Performance wise there is no doubt the K3 bests them all, I recently built a K2 and think that's scarily good in raw performance terms as well. My K3 is pretty much fully kitted out and I have a P3 as well which is extremely useful and they're going nowhere.

 From the super small super portable super capable K2 and KX3 to the small and portable and no less capable K3/K3S their market segments are well covered but KenYaeCom have surely sold enough
TS990,FT9000,IC7800/50/51 that shows well the market demand for a quality high end desktop sized radio. If the pictures on QRZ are anything to go by not everyone operates out of a shoe box with many having dedicated rooms for their radio hobbies. If the shoe box is your limitation then the K3 is undoubtedly a superb choice but where space is less restricted a bit more in the way of panel acreage might well sway a lot more FT9000/TS900/IC78xx users I feel, not to mention those of us who just feel the K3 package is, for a desktop radio, just a bit too much of a compromise.

Key requirements on my end after considerable K3 usage. A better more up to date menu system that either removes or better, handles the myriad un-intuitive selections. There are a number of menu options which unless you have significant handbook familiarity lack explanation about additional keypad presses. There are even some for which software updates need to be consulted though that is a different matter. Some menu choices could well be better homed as front panel controls. The keypad is another area I find seriously lacking for a top end product. 
Again, great for the type of product it is but I find it lacking. Band keys, mode keys, a proper band stacking register, a better way to deal with the sub receiver settings, more, bigger and wider spaced control knobs, yes all of this needs panel space but that shouldn't really need to be a problem. It's possible the entire form factor could use a rethink, do we need a box 12 inches deep. Why not a front panel that is
16 inches by 6 inches on a radio that is just 5 inches deep. Overall it would likely be a similar volume and contain just as much under the skin. The Orion was probably overkill with the amount of fresh air in every box, some careful plug in board stacking could have reduced the box depth by half whilst retaining the same front panel space. A good display with all info including the somewhat obligatory scope and waterfall properly integrated seems a no brainer today I guess, of course with a port for connection of 36 inch full 4k displays, ideally with different screen displays.

I like the PA options today 10 or 100 watts, not sure how many are sold as just 10 watt radios though. In a bigger box, something like the 7850, 16x17x6, it should be possible to integrate the KPA500 allowing for a
500 watt transceiver in one box.

Where space is a premium the integration of multiple controls carefully arranged for maximum apparent efficiency is obviously a good thing though I feel it can be overdone, the poor operability of the sub receiver is a case in point and I've had heat of the moment run ins with the mic gain compressor and monitor controls as well. Great when it works as you think of it, less so when you're acting more by feel and intuition doing 6 other things at once and get a mis-press.

Much of this is software, packaging and ergonomics/HMI, so far as the pure RF side is concerned it's clear that things are evolving still and it can't be long before pure wideband direct digital SDR becomes the mainstream.

It's hard to fault the K3 on so many levels, it's just such a great radio but it's by no means an unflawed or unlimited radio and there are areas of the ham radio business Elecraft are yet to tread.

Oh and I'd love them to do a 2-35Mhz 125 watt radio suitable for commercial use. So many opportunities where the options today are either VK mobiles or US mil spec but that really is another topic.

I have used my K2 with a DEMI 2M transverter board in it to drive
transverters from 902 through  10368 MHz for many years.  When I used it to
drive both 902 and 903 MHz portions of that band, the output was very much
lower when 29MHz was in use for 903.  I can't say whether it was due to the
29 MHz IF or the 144MHz transverter output.  I didn't pay much attention to
spurs as 902/903 is a trashy band anyway.  I have made many nice QSOs with
the setup.

I was thinking along similar lines.  If enough hams find the smaller K3 
front panel difficult, (and are adverse to present computer-based solutions) 
maybe an external box that has LOTs of knobs, etc... that plugs into the K3 
DB9, could be made.  Using any one of several 
microcomputers/microcontrollers, such a box could be designed.  It might be 
somewhat costly, as buttons, knobs, displays, are all physical devices that 
cost $$.  But, this might give some hams the best of both worlds.  A compact 
rig when needed, but lots of buttons, knobs, displays when someone wants 
them.

I've done some limited K3/KX3 remote control with Arduinos (and wifi), I 
doubt a simple Uno would be sufficient.  But some device with more GPIO pins 
and memory could certainly interface to the K3/KX3.  Such as a Due, 
Raspberry Pi, BeagleBone Black, Teensy, or even an Arduino Mega.

Interestingly, I now have three "retro" 8080 CP/M computers that use a Due 
(or Mega) to emulate a whole Altair/IMSAI computer box.  These devices have 
enough I/O pins to support all the switches and LEDs of an original Altair 
front panel and serial I/O - without any multiplexing.  Using encoders 
instead of pots would help reduce analog I/O for a radio interface for 
example.

Is there much interest in such a device?  If so, maybe a group could discuss 
this more, and come up with some specific front panel control/display 
requirements.

Note that I am happy with my K3 as-is.  Also, several computer control 
solutions already exist, so I assume that this would be a very limited 
"market".

If you are used to working large rigs with lots of buttons, I can see how 
the K3/K3s might be an adjustment.

I have found the K3 controls to be natural and appropriate.  For most of my 
operation the buttons and dials I need to use in action are right at my 
fingertips.  Once set up correctly, I find little need to venture into the 
menu system on a day to day basis.

Sure. It would be nice to have band and mode stacks.  But is it that big a 
deal, worth spending many thousands of dollars to change?

We will gain nothing in performance with a bigger rig.  Already Elecraft 
outperforms ALL of the big boxes on the market, per Sherwood Engineering.

Here is an elegant and simple solution for the K4 that will satisfy the big 
box demand.

Design a modular big front panel that simply plugs into the K3.  Design 
should be relatively easy because you don't have to change the K3s itself, 
just add a command and control interface for the larger front panel.  Can 
you use the accessory port or do you need more connections?  I don't know I 
am not an engineer.  Currently computer radio control programs work with a 
simple DB9 connection.

Then give an option of mounting the K3s in a larger box.  That would have 
the added convenience of making it easier for us klutzes to be able to get 
into the rig to make changes such as adding filters.

So, you would have options:
1. standard K3s
2. Standalone large front panel.  Put your K3s under the table and mount 
your front panel wherever.
3. K3s in a larger box with the larger front panel mounted on the front. 
You can even add options to the large box such as nicer stereo built in 
speakers, even a built in AC to DC power supply.

It will all still be the best HF radio in the world, made right here in the 
US.

I upgraded my early production K3s most of the way to K3Ss by installing 
the new synth boards and the new transverter board (for the preamp), and 
I'm a very happy camper.

Which is why to replace (or add) the newer KXVB board, which includes a 
second preamp that can be selected above 15M.

My experience is quite different. From the beginning (in 2008), I found 
the user interface very well thought out. Maybe that's because I started 
by RTFM.? Everything I need while operating is on the front panel. The 
menus are organized so that they are almost never needed during 
operation except to fix a setting that was wrong in the first place. I 
can't remember the last time I needed to go into menus for anything but 
setup with new outboard equipment.

My K3s replaced a pair of FT1000MPs. Everything about the K3 performance 
and user interface is far superior. AND the change freed up a LOT of 
space on my operating desk!

My experience is similar to Jim's. I used an Icom 706MK2G where 
the UI drove me up the wall. I particularly like the way I can 
change between CW, digital, and voice with the K3 without having 
to change plugs like I need to on the KX3.

One improvement I can think of in the K3 UI is in setting the 
noise reduction parameters. They exist on two dimensions, but 
the adjustment is only done with one knob. Perhaps the 
adjustment would be more intuitive if the two bandwidth 
adjustment knobs -- shift/lo and hi/width -- were temporarily 
changed the adjust the two dimensions until leaving NR 
adjustment mode.

Thanks, Dave.  

Were you using a K60XV transverter interface or the QRP antenna jack for transmit output (and if the latter, at what power level) ?

 I have
 used my K2 with a DEMI 2M transverter board in it to drive
 transverters from 902 through ?10368 MHz for many years.?
 When I used it to drive both 902 and 903 MHz portions of
 that band, the output was very much lower when 29MHz was in
 use for 903.? I can't say whether it was due to the 29
 MHz IF or the 144MHz transverter output.? I didn't pay
 much attention to spurs as 902/903 is a trashy band
 anyway.? I have made many nice QSOs with the setup.

 The K2 is specified to operate

 I have wondered about using a K2 as an IF for VHF
 transverters at around 29-29.4 MHz (to avoid interference
 with bands using 28 MHz IF).
 
 
 
 Both of my K2s seem to operate (VFO synthesizer works) up to
 30 MHz.? At 29.5 MHz the available transmit power (QRP) is
 starting to drop off and this is quite noticeable at 30
 MHz.? The QRP PA efficiency drops off somewhat as well.?
 There are a few receive birdies on the 100 watt radio, but
 the QRP one is pretty quiet - nothing that should be
 noticeable under the extra noise coming from a
 transverter.? Turning the preamp on makes extra noise as it
 should (but it is after the bandpass filters so that
 doesn't mean a whole lot).? But it seems that it should
 work ok as long as I don't want more than 4-5 watts
 (most likely I'd use a K60XV), perhaps with a bit of
 bandpass filter tweaking.
 
 
 
 Are there any caveats that I am unaware of?? Spurious
 emissions, perhaps?? Has anyone tried using their K2 above
 29 MHz?

Hello Ken & Bob (callsign?),

I?m very sorry that you and others seem to feel annoyed because of the K4 discussion. This was not my intention but I?m a bit disappointed that this quickly drifted off into a 'so why did you buy an Elecraft product' debate instead of discussing things more objectively.

Someone was asking about a K4 and I just started to think out loud what in my eyes would perfect the K3S or even justify a new model. This was not meant as criticism. However, my points did not come 'out of the blue' as I and others have been collecting notes since the K3 hit the market. Back then and after careful evaluation of an early model we just silently went with another product. Since then many issues have been addressed making the upgraded K3/K3S a mature product, and my list has shrunken to the aforementioned points. It now seemed appropriate to articulate them.

I?m not expecting at all that someone will build a radio to my personal needs. Most of it is subjective and debatable, anyway. But we all would agree that time moves on and it does make sense to help such a responsive company like Elecraft with new ideas which they might consider for future products. As a long-time reader of this list I understand that it has been this way all the time and hence I don?t feel it is wrong to mention possible improvements.

It is absolutely fine if you are happy with your early serial number K3. However, there may be issues you are not aware of and for good reason Elecraft has come out with upgrades. One example is the CW timing issue of the K3 with the old synthesizer as mentioned earlier:
http://lists.f5mzn.org/pipermail/support/2013-November/083384.html
http://mldxcc.org/n6tv-k3.pdf

There are still a few CW signals on the bands, even highly respected and successful contesters, which can be recognized by their choppy keying. If you are not into CW faster than about 32 WPM this is not an issue. But an early serial number K3 is not an immaculate radio.

As stated by others Rob Sherwood measures just some aspects of the rigs performance. These do matter if you are into serious DX-contesting with big antennas. But there are other technical and operational aspects which are not covered and he never intended to do so.

Getting back to the first two points of my list which unintentionally contained a comparison with newer ICOM rigs:

- Yes, to me it is amazing how ICOM does it, but the NR really works excellent and everybody else who has operated an IC-7851 will agree. 

- ICOMs APF is easier to understand: It is basically a DSP audio filter with preselectable bandwidths of 80/160 or 320Hz in context with a 0-6db amplifier. This makes it useful as a quick option to emphasize a weak or disturbed signal. Elecrafts APF in contrast has a fixed 30Hz bandwidth and is more suitable to emphasize a very weak signal when you have the time to tune it in. The ability to select both APF paradigms would be awesome. But again, this is debatable. 

Having said that, I love my K3S and although it took a few years it has now become my preferred CW rig.

Message-ID: <CACVQm3nyiEO-M9p6e=6orpjZbSbRjersbfJ4M5HRdxoFJY_2-Q@mail.gmail.com>

Just finished my first contest with the KPA-1500.  Unit arrived yesterday
in perfect condition.  Packaging very professional.  Putting on a new 220v
AC plug took the longest of anything.  Probably made the first Q less than
an hour after the box was dropped off at the door.

Today was just a short CW contest (King of Spain).  Everything was great.
The fans do come on rather quickly even in a CW contest but with my
headsets noise level wasn't objectionable.  Will see when it comes time for
a RTTY or SSB test.

I did notice an occasional flashing of yellow and red in the SWR led
string.  I watched my inline meter and it showed nothing during those
bursts so something is going on there.  Believe this was noted by others.

I ran the contest with 40w of drive from the TS-990S and produced in the
area of 1400w.

So far quite pleased.

I agree the K3S fills in most all of the shortcomings of the early and even later K3's.   That's why I purchased a K3S.  After almost 3 years now of daily usage, it is now at Elecraft for updates. 

I'm very satisfied with the excellent performance and the ability to customize a radio to my preferences.  I'll pass on the assortment of "cookie cutter" radios from other companies.

Likely ALC overshoot (momentary overdrive) from the Kenwood rig.

"...did notice an occasional flashing of yellow and red in the SWR led
string.  I watched my inline meter and it showed nothing during those
bursts so something is going on there. (etc.)"


This is common with the new amp.  Elecraft is working on a firmware update 
to correct it -- hopefully. Just ignore flashing LEDs for now.

I am currently using two K3 radios with various updates including the new synthesizers, and see no reason to go the the K3S model. Years ago I added the second receiver to my original K3. I liked the diversity capability, but I am not much of a DX'er and eventually got rid of the second receiver.

I went to the K3 from an FT-1000D, and found the K3 user interface very well thought out. Not at all hard to learn with respect to the most needed controls, although more obscure functions still have me looking in the manual. With that said, and since we are discussing possible improvements, I can suggest the following:

I immediately missed the lack of band and mode buttons. Not a big deal, but still noticeable on a frequent basis after many years.

The 4 controls with dual green LED's have a flimsy, cheap feel. The combination of multiple functions is perfect, but something used so often should feel super solid and expensive.
My short term memory is bad, and I constantly find myself activating one of these controls just to see the current power setting and cw speed etc. Dedicated display real estate would be an improvement. I am ashamed to say that I haven't looked closely at whether one can always display the current setting witout changing it, but the reality as of right now is that I frequently go through the motions of changing a setting just to get it displayed, and then changing it back. This is a lot of wasted effort. 

The pushbuttons can sometimes malfunction if one doesn't push hard enough, and the dual functions (good idea in general) should be enough justification for buttons with a "Rolls Royce feel". In some cases dedicated buttons would be justified as opposed to the dual functions. I got the DVR option for one of the radios and expected it to be used a lot for getting a second chance to copy something deep in the noise during a contest. I actually never use it because I am not consistent enough in achieving the HOLD of the button that is required, especially in a busy situation. There were several reasons I sold the 2nd receiver. Not involved in DX chasing, I didn't have enough need, and I didn't have enough real estate to make the most of the diversity capability. For years I didn't have much time to operate, and I often updated the K3 firmware just to get on the air for a short period of time. This erased my settings to suppress the birdies caused by the second receiver. Being a bit of a perfectionist, I would spend an hour entering new settings. Yes, most of those birdies were weak enough that they didn't affect my ability to copy any given signal, but when tuning around each birdie would cause me to pause unnecessarigy for a fraction of a second. Yes, I could have spent some more time than I did adjusting the cable positions inside the radio to minimize the strength of the birdies, but I did spend time on it, and noone has told me that that would eliminate them entirely. I would hope that the K4 will change something fundamentally in the design so as to effect complete elimination of the birdies. Last but not least, I was never comfortable with the user interface for the second receiver. The status of it needs to be more visible through dedicated display real estate. 

Although one can argue for additions to the front panel controls and display items, I would not want anything like the size of yakencom top-of-the-line monsters. For one thing, I want my radios to be easily liftable. Something like my old FT-1000D is a nightmare to lift. Also, too much front panel real estate is a problem in SO2R operations, where you have to reach everything quickly. I think most if not all of what I have asked for above could be achieved in a front panel size matching that of the KPA1500. This would be a logical move for Elecraft.  Since I have added P3's to both radios, I wouldn't consider being without them. I doubt that a P3-size screen could fit in the KPA1500 size front panel, but since the P3 takes up the space anyway within the reach of the SO2R operator, I would be fine with the KPA1500-sized front panel lengthened by a P3 width. Surely, the combination of the two units would make possible some improvements in panadapter controls and, additional uses for panadapter screen display items.

Although I mostly operate cw, I have recently been on 20 ssb a bit. I have found that most ssb stations on 20 are effectively channelized. When manually scanning the band I save a lot of time by using the RIT knob as a tuning knob with 0.5 kHz steps. I sometimes wish that knob were bigger and with better feel. The high resolution of the P3 display shows great differences between different stations, and the visual differences often correlate with what one hears. If a station has inadequate emphasis on the highs (or excessive lows), that is easily seen. Also, some stations stand out for having clean smooth flanks, while others have ragged flanks. IC-7300 stations seem to consistently be in the clean-looking group, and sound a lot better than stations with muddy flanks. I have not gotten a feel for where K3/K3S stations fall on the scale, but notice that I haven't been getting a lot of compliments recently compared to years ago. If indeed the K3/K3S should be a little behind at this time, I would guess it might show up visually on a good panadapter, and that would reinforce any negative impression from the audio. Then of course the muddy signals I see on the P3 may result mostly from overmodulating etc and not necessarily from the equipment design. Anyway, I think many or most of the panadapters that people have built into their radios are inferior to the P3, and don't show much detail in an ssb signal.

OK, Dave.  Yes, I am somewhat familiar with DEMI's predecessor of the K60XV.  It had no Elecraft-style power control, so it wouldn't surprise me if the power fell off with frequency above 29 MHz.  I guess I should test the 29+ MHz output level of the K60XV in the K2 I have with one installed.

Thanks for your info.

 Well now
 -- I don't think I was using the K60XV.? When Steve
 Kostro developed the DEMI board, it just was wired into some
 point on the ?output chain.? He changed the ON/OFF Power
 switch on the back to select either the HF QRP signal or the
 output of the transverter board at the BNC connector.? The
 output of the transverter was about 22 dBm or 220

  Me too.  After I determined some years ago that my then-new K3 was actually working, I gave my Yaesus away - both of them.  I haven't missed them since.  My backups are now a pair of K2s at one QTH and a KX3/KXPA at another.

If there were one additional item on my list it would be having an internal keyer that would make external logging programs redundant.  And the NR system . . . 

Apart from that, and apart from my own ergonomic preferences, I am willing to bet that whatever comes next isn't a bigger box but rather the other way around.  I have heard the K3/S described more than once as an SDR with knobs.  Maybe.  But my bet would be , if there is a K4 or some such, it will be an SDR without knobs.  Any takers?

I definitely would like to see mouse control for the P3... The current
buttons and especially the rotary encoder are stiff enough so that the unit
moves when they are pushed. With a mouse controlling these features the
unit is not touched. A USB port to allow the use of a wired mouse or a
dongle with a wireless mouse would be ideal.

Also, the addition of a HDMI port in addition to the SVGA. More of the
larger monitors are coming without SVGA inputs. It would also be a way to
send l&r audio to speakers in the monitor.  HDMI can be used for split
screen video (PIP) allowing several windows  with different displays to be
shown on a single large monitor.

An additional rotary encoder on the front panel of the K4 to allow for
1-5-10-20-50 KHz tuning steps across the band. Currently, the RIT/XIT knob
can be reconfigured for that function.

A small slot on the back of the radio to accept a computer cable lock for
use when the radio will be used at public events like Field Day, etc. This
should be added to the whole line.  It will not stop a determined thief,
but it will deter some.

A couple of more antenna ports on the back to allow several different
antennas with memories for the tuner settings for each.

More programmable memory buttons so that voice recorder is not using the
same ones as CW or Digital.

Backlighting on all the buttons and controls......

50 Amp power pole connecter for incoming power, keyed so that the KPA1500
power cable will not connect. 2 standard size power plugs for aux power out
to P3, etc. Main power cable upgraded to #6 wire.

If you watch Rob's presentation here: 
https://www.youtube.com/watch?v=owaaT6u4XkY&index=10&list=PLRSwUN4qr1LpU_cjWRYvszhDggoqlEQFF
you could note the sales figures for the ICOM 7300, an SDR radio WITH knobs.

Currently available radios without knobs are sold by Flex and Apache.? But now 
Flex has the "M" series with knobs.? Maybe that says something about what the 
market prefers.

Personally, I want knobs.

I know that many people love controlling everything from a PC, but that is for me a don't-want, as I don't want the extra box to start up, and using a mouse and keyboard is much less convenient than knobs. Of course, using contesting software does involve the PC, but even in that situation I want my knobs. Controlling the rig from a PC repulses me even more so lately, since Microsoft is forcing software updates on us ever more frequently. Very disruptive. I do understand that increased vulnerabilities demand it, but then the vulnerabilities are caused by Microsoft itself, always adding functionality without concern for security (except for Microsoft job security). Some will say that Linux is the answer but I have been there, and I would prefer a special version of Windows that removes a lot of bells and whistles and doesn't need frequent updates. Has anyone investigated which ham software products work or don't work with Windows set to protected mode?

On the subject of panadapter features, I can see some utility in using a mouse, as pushing the P3 knob does indeed tend to move the whole box. However, unless there is software based automatic fine tuning, I find that mouse clicking on a signal usually requires fine adjustment with the tuning knob. The advantage of the mouse then is the ability to make large jumps without a lot of knob spinning. That need is sharply reduced by using the RIT knob as a coarse tuning knob. 

Perhaps the K4 packaging should place most of the P3 electronics as an optional plug-in board inside the radio, and place a slightly bigger display in a separate, P3-size box. The P3 controls would be on the radio. The existing controls for the second rx could be kept for those who can stomach them, but a new button on the radio would switch the P3 display to show all aspects of second rx settings, and allow adjustment. Another press of the new button, or a number of actions such as moving the main tuning knob, would go back to normal P3 display.

Subject: [Elecraft] [K2] Using the K2 above 29 MHz
Message-ID: <201805200029.w4K0TtAd022755@mail47c28.carrierzone.com>

Steve - VE3SMA,

I see the same thing on 2m using my K3 with a DEMI transverter.  The 
K3 will tune 28-32 MHz in transverter mode but there is not enough 
drive above 30 MHz.  My 25w transverter drops to 7w at 146.52 (30.52 
MHz IF).  So its not usable at the FM end of 2m band.

Whether this a limitation of the DEMI unit or K3 is 
debatable.  Result is unusable.

Rather than get upset, I just use a 2m-FM radio at frequencies >146 
MHz.  But I see your conundrum as you would like to use a higher 
freq. for IF on mw.

KX3-2M works fine over full band, and the KX3-2M is my mw IF radio.

Message-ID: <f84f5eb7-6b0c-2a6b-5f1b-f960817305d5@triotel.net>

Preliminary comments subject to learning more and operator error so FWIW.

First a few of the good things I will comment on which are just of few 
of the many good things.

KPA-1500 drives really easily.? I don't come close to needing 50 watts 
even on 10M and 6M to get 1500 watts out.? I have confirmed this is true 
using a LP-100A watt meter in addition the KPA-1500 LCD reading and LED 
reading.

Fan noise seems plenty low enough.? Of course only on SSB is it going to 
be picked up by the Microphone.? The? highest fan setting will obviously 
be on RTTY.? Using it on SSB I get good reports, ie low back ground 
noise and I see very little power out on the watt meters when not 
talking.? The true test will be in serious contest efforts but it seems 
to be fine to me.? The RF deck fan moves a lot of air in position 1 or 2

The power cord is nice and long for the 240 vac so between it and the DC 
voltage cable being reasonably long it gave me a lot of flexibility.

Instant on, instant power, no tuning, instant band changing just like 
the KPA-500. It will really be nice for higher power when needed plus I 
can use it from AZ in the winter time.

Nice having the PA temperature showing on the LCD.? When I seen 0A on 
the LCD I wondered if it was an error code.? I could not find it in the 
manual although later I did.? Once I put some power out ti was obviously 
amps!

BTW the PF1 macro I had set up in the K3S to turn the KPA500 on and of 
remotely works with the KPA-1500.? It will be pretty amazing to? operate 
the KPA-1500 at high power remotely when needed.

Basically as advertised, well worth the money IMHO.? With the devices in 
it and if the protective circuity works it should last a long, long time.

Some Concerns

SWR LED indicator flaky.(Been reported and I am sure will be fixed with 
firmware)

On SSB key up? there is sometimes power out without talking? In fact 
sometimes 200-300 watts on the LED.? Way..... less on the LP-100A watt 
meter so like the SWR LED something seems messed up. However once I say 
something it is much better so I don't think is is the microphone 
picking things up. By much better maybe 1 or 2 watts. ? I don't use 
ALC.??? More to be learned here but this is what I? believe I see here 
on some on the air checks.

Have what appears to be RF getting into the LCD meter on 12M on CW but 
very little on SSB.? No problem with this on any other bands.? If I turn 
the power down to about 800 watts out on CW it goes away. Things are 
missing and scrambled on the LCD read out. SWR/Reflected power is low on 
12M.? About 1.3 to 1.? It works OK looking at the Utility program so it 
just seems to be RF messing up the LCD meter.

ATU is great for stations with one antenna per band or less or even for 
more than one antenna such as for DXing.? It does not do the job for 
contesting with multiple antenna's per band if they have some SWR.? It 
is not a problem if the SWR is low then you can just use BYP?? Wayne 
says this will eventually be addressed via firmware.? Until that happens 
I need to do some antenna work outside so I have low SWR for contesting 
with multiple antenna's per band.? This is always better anyway.? The 
ATU will retune on the "FLY" but to me does not seem useable for contest 
switching of antenna's, way to slow,? if there are significant SWR 
differences.?? For me It will depend on the firmware fixes and how they 
are implemented.? My solution will be to do some antenna work this 
summer..? I could get by with tube type amplifiers but with SS not so much!

KPA lead time for -new- orders was posted at 9 weeks on the shipping status page just last week, right before we left  for Dayton. (A drop of 2 weeks from our prior estimate.) 

We?re shipping at a good clip and have been driving it down steadily. We will update it late next week after we tally our new backlog total vs shipping rate.

With the advice and counsel from a number of people on this reflector, Jim Brown K9YC notably among them for the time he devoted to my follow-up questions, I have worked out how to get the 240 VAC safely where I need it -- and so, last Monday, I put in my order for the amp.

This was my concern, as well, when first considering buying a solid 
state amp.? (KPA-1500 is on the way.)? I want a control input on the amp 
I can connect to the switch that selects antennas so the ATU will switch 
between at least two sets of settings for each band.? As that didn't 
seem to be forthcoming, I built a tri-band tuner box, with 6 L networks 
and relays.? That gets both my tribanders down to close to 1:1 on all 
bands, at least in the CW segments.? It would still be nice if the ATU 
in the amp could follow the antenna selection.

BTW, I use a little toggle switch to select the tribander.? I can switch 
it several times while a station is calling to determine which antenna 
is better.? There's absolutely no way one could do that with a mouse.? 
Maybe hot keys would work, but I like the idea that the station can 
function independently of the computer, even though I use one for contests.

At least I have failed to hit a setting for CW which works for me. The NR also seems to be dependent on AGC settings. With the IC7851?s NR at ca. 9 o?clock the band noise is cut about in half without affecting signals, even when they are weak. I do not miss this much in everyday operation. But the additional band noise really hurts in my ears when doing SO2R causing fatigue and ultimately increased error rate.
I know NOTHING of the "I" radios including their NR or NB capabilities 
or approach.
I DO know that Elecraft's NR system has never failed me.? I failed IT in 
the beginning, but not PROPERLY EDUCATING myself on its operation and 
PRACTICING the task until it become second nature, like tuning the VFO.? 
Once you have actually used it and understand it, you will find that you 
can zoom in on the right NR selection in the heat of battle just fine.? 
<Smile>

> - I continue to be impressed by ICOM?s APF function. Combined with a few dB of additional amplification in the APF level menu this sort of has become a great ?panic button? for me when a weak station calls or QRM shows up. Elecrafts APF is way too sharp for this purpose. Maybe another APF with wider bandwidth could be added?
Again, I know nothing of the APF function on the "I" brand.? But I 
absolutely LOVE the APF on my K3s.? Yeah, it's narrow.... that's the 
point.? The trick is to do things right from the beginning.... First, 
you need to tune the frequency properly..? Use the FINE setting and dial 
it in to the 1 Hz.? If you get "lost" use SPOT to get in the 
neighborhood again and then tune.? This is ONE of the reasons I have the 
better TXCO, use a good time source, and keep my set calibrated as 
accurately as possible with the tools I have at hand.

You can shift the APF center freq, but that's 5 Hz.... and a workaround 
for lazy tuning.? Another option is to prepare your presets and set APF 
to be ON on one or the other.? That way you don't even have to reach 
over to that button panel.? You can stay below the screen around the VFO.

> - Elecraft should consider adding mouse support for the panadapter.
THIS would be great...? I'd love to have point and click tuning at least.

> - Coming from ICOM rigs I noticed that the knob resolution seems slow. This sticks out with the filter, RIT and power knobs. Too much knob spinning required for my taste. However, this may be subjective and there are work-arounds.
"Slow knob resolution"?? You mean high resolution, right?? Because 
that's what they are.? I absolutely love them.? Not twitchy at all and 
give me finer control over settings....? Again, the key to making these 
"slow" knobs hum right along is PRACTICE using them.

> - I would also like to see Elecraft using higher quality buttons which are more responsive. When the K3 came out one of the reasons I never got one was the wobbling feel of the A/B (and other) knobs. It simply was not compatible with my style of operation which involves constantly switching VFOs when S&P. Yes, there are work-arounds, too.
I'm actually 180 degrees out from you on the push buttons..... they are 
"wobbly" so you can hit them at larger angles (activation cone).? This 
is awesome for touch tuning.... mobile.... contesting.... et al.? They 
actually remind me of the buttons on a lot of military gear.

Y'all have a great evening!

Mmmmm.....? ESSB can transmit with right at 4 kHz bandwidth...

I can't imagine that something can't be done in firmware to make it 
possible in a digital mode....

WHY are they allowing digital modes to have such a huge bandwidth?? 
Seems counter-intuitive to me, but I am not a digital guy.

I will NEVER voluntarily give up my K3s....? Not saying I won't ever buy 
another radio, but I dang sure don't HAVE to!

I bought Elecraft FIRST for a reason....? I didn't want to follow that 
ultimately wasteful path of buying old, sub-standard radios, and buying 
10 radios in a serial fashion while never being happy.

I have not regretted ANY of my Elecraft purchases for a minute.... ever.

Clay, the individual signal with many of these digital modes modes is
actually quite narrow, on the order of tens of hertz. It's just that by
convention, everybody uses one SSB frequency for a given mode (such as FT-8
on 14.074). That means there may be dozens of QSOs going on in the
equivalent bandwidth of one SSB conversation. The computer decodes all the
signals in the receiver passband all at once, but you need to pick a spot
within that bandwidth to place your transmit signal.
Obviously if you pick a spot outside the transmitter's audio band pass,
things won't work too well.
That's not really an issue with FT8 if the software is properly configured,
as it will automatically shift the VFO slightly on transmit to keep your
chosen transmit audio frequency in the sweet spot of the transmitter audio
bandpass.
Fortunately, this tends to keep all that FT8 activity within about a 4 kHz
slice of the band, so the rest of us can easily avoid it if we choose to.

Yup...? RTFM....

I read the Op manual 4 times from cover to cover before the radio even 
arrives (assembly manual 3 times).? Then, after it was built I went 
through it page by page and used EVERY single function and looked at 
EVERY single menu location.? I have binders with every manual with 
changes posted as a manual backup in case the power fails.? I go through 
and check for docs updates monthly on every piece of equipment I own.? I 
read the K3s Op manual cover to cover minimum twice a year.... and of 
course every time I do something obscure like build a custom K3s, P3, 
3rd Party Amplifier interface cable harness.

RTFM....? When I was a young guy, I could read it once and basically 
have it stored like a photo.? Not so much anymore.... age or experiences 
(I don't know which) somehow broke that feature.

73, Jim....

Good evening,

 ?? A cool week with some dense mist.? The ferns are getting taller but 
far from completely unrolled.? The bracken fern is over six feet tall 
while the sword fern is just getting started.? Where the bracken fern 
dies back with the first few frosts the sword fern only dies in the 
early spring when the new growth appears. They only get to about four 
feet tall but they can cut you.? Just one more shade of green in the 
misty forest.

 ?? The sun is blank again.? Space weather says we are in a quiet region 
"between streams of solar wind".? Quiet is good; strong signals are 
better.? I'll probably be off net frequency a bit because with 
conditions like these I can hear well but the other folks on frequency 
cannot hear me (without a scorecard).? Working either 0.5 above or below 
the specified frequency helps me find an open space; hopefully for the 
entire net.

We'll also be able to execute P3 macros directly from K-Pod switches, as well as 
use the K-Pod's knob to control the marker knob on the P3.

In the process of listening to the receiver I would not want that overlaid with voice responses from a UI dialog. Also, a voice response immediately goes away, just like a number temporarlily shown in the B display. On a more personal note, I also find all artificial voice applications enormously irritating. I refuse to speak to my car to ask it to do something, and refuse to use Alexa or Siri etc in a voice mode.

Make the displays audio readouts instead, then you wouldn?t need so much room, nor would it take up as much battery life if it were powered by battery!

I know that many people love controlling everything from a PC, but that is for me a don't-want, as I don't want the extra box to start up, and using a mouse and keyboard is much less convenient than knobs. Of course, using contesting software does involve the PC, but even in that situation I want my knobs. Controlling the rig from a PC repulses me even more so lately, since Microsoft is forcing software updates on us ever more frequently. Very disruptive. I do understand that increased vulnerabilities demand it, but then the vulnerabilities are caused by Microsoft itself, always adding functionality without concern for security (except for Microsoft job security). Some will say that Linux is the answer but I have been there, and I would prefer a special version of Windows that removes a lot of bells and whistles and doesn't need frequent updates. Has anyone investigated which ham software products work or don't work with Windows set to protected mode?

On the subject of panadapter features, I can see some utility in using a mouse, as pushing the P3 knob does indeed tend to move the whole box. However, unless there is software based automatic fine tuning, I find that mouse clicking on a signal usually requires fine adjustment with the tuning knob. The advantage of the mouse then is the ability to make large jumps without a lot of knob spinning. That need is sharply reduced by using the RIT knob as a coarse tuning knob. 

Perhaps the K4 packaging should place most of the P3 electronics as an optional plug-in board inside the radio, and place a slightly bigger display in a separate, P3-size box. The P3 controls would be on the radio. The existing controls for the second rx could be kept for those who can stomach them, but a new button on the radio would switch the P3 display to show all aspects of second rx settings, and allow adjustment. Another press of the new button, or a number of actions such as moving the main tuning knob, would go back to normal P3 display.

The zero just means that the fans are off (manually).? You can set the fans to be on at speeds 1 through 5 regardless of temp.? They will stay on continually.That said, the fans will operate automatically according to temp.? They will ramp up as the temp increases.? I think the first to engage is the center fan but youcan easily see this yourself.? I did some CQing in the King of Spain contest to get the temp up and test things out.? They indeed came on at 60C.? I forgetwhere I stopped, I think at 71C, but the fans will come on starting at 60C with the fan speed on zero.
I? will give it a more robust test this Wednesday during the cwts but that is only a one hour test.? During WPX at the end of the month I will probably set thefan speed to 2 to get more cooling power below 60C.? When the PF1 & PF2 buttons become programmable I will probably set them to turn the fans on or off.For me a fan speed of 2 is acceptable during a major contest situation even with headphones off which I really never do normally.

I did find it interesting tonight to see my shack tv get blanked out on xmit.? I only checked 3 bands.? TV was ok on 80mtrs but blanked the picture and soundout on 20 & 40 mtrs, hi.? That never happened with either of my tube amps.? I will look into that at a later date.
Good luck with your amp.

p.s.? The pwr supply fans run whenever you turn the amp on but fans set at zero no amp fans should be on until 60C.

 Bill,

My KPA1500 also defaulted to FAN SPEED MIN = 0, but that is not fans off 
(at least not on my amplifier).

My fans engage at 60c (low), 65c (medium) and 70c (egads).

Is there a menu explanation somewhere about the start/stop temps and 
speeds? I would like a little more hysteresis in the 60c setting: start 
at 60c but continue cooling until temp drops to 50c. That might work a 
little better when running digital modes with long Tx/Rx intervals.

This is common with the new amp. Elecraft is working on a firmware update 
to correct it -- hopefully. Just ignore flashing LEDs for now.

I have to agree with the posts noting with disappointment that Elecraft 
has not, nor seems to show little interest, in producing a new 
competitive desktop radio.? That said, I'm sure they are working on one, 
but when produced, the market may be saturated with other manufacturers 
radios who have felt the need to get to market quickly.

It doesn't matter that the K3(S) is a truly fine and competitive radio.? 
It isn't a matter that the performance ratings of the newer radios are 
significantly better (they are not).? It comes down to we who love 
technology and wish to be on the cutting edge; to have a unit with the 
latest bells and whistles.? The K3(S) for the most part, is technology 
over a dozen years old.? To wit, I have grown tired of looking at the 
same radio for over 10 years, from my early S/N K3 to a second and newer 
radio, a K3S.? Ho, hum.

At the price of newer, competitive radios, trading newer for older or 
one radio for another becomes less attractive.? I have already seen in 
abundance those who have already discarded the K3(S) in favor of Icom's 
or Flex's newer offerings, not only contesters but DXers as well. I have 
not yet, but may soon.? Should Elecraft come out with a K4 or whatever, 
regardless of it's feature set, they've already lost advantage and way 
behind the market.? Of course, we who drink the Elecraft cool-aid will 
no doubt purchase.

To those that say "moving on" is unnecessary, I ask how old their 
vehicles are?? I buy a new vehicle, not often, but every 5 to 7 years 
not because the older car doesn't get me from point A to point B in fine 
fashion, but because I just want something more recent with newer or 
upgraded options.? How about your cellphone? How many are using one 10 
years old?? It's personal preference just like it is for radios.

Dan summed it up perfectly with his analogy of the car and cell phone.
Some of us (maybe lots of us) want modern features in our cars, cell
phones, and yes, our transceivers.  I bet very few people buy a car because
of the features of the engine, transmission, tires, etc.  We buy one 'cuz
we love the features and comforts offered to the human operator.  We might
not buy a new one every year, But...

There's lots of cool technology out there and the K3/K3S are beginning to
look a bit outdated compared to the competition.  As others have already
noted, the display is old tech, the P3 is a separate unit, knobs and
buttons, NB/NR, SubRX Integration, etc.

I love my K-line - In the end, I voted with my wallet: K3/SubRx++, P3 and
KPA500.

I look forward to seeing the company continue to evolve its flagship line!

Heh. ? Jerry and I have ulterior motives for this suggestion, although we also understand that y?all light dependents won?t give up your distracting visual displays until they?re pried out of your cold dead fingers. :-) So I?d happily meet halfway and have spoken (or morse!) output in addition to rather than instead of. Like the morse readout on the KX3, except with all function readouts available. Or like the functionality of the Hampod (http://www.hampod.com/ <http://www.hampod.com/>) built in.

Of course, using contesting software does involve the PC, but even in that situation I want my knobs. Controlling the rig from a PC repulses me even more so lately, since Microsoft is forcing software updates on us ever more frequently. Very disruptive. I do understand that increased vulnerabilities demand it, but then the vulnerabilities are caused by Microsoft itself, always adding functionality without concern for security (except for Microsoft job security). Some will say that Linux is the answer but I have been there, and I would prefer a special version of Windows that removes a lot of bells and whistles and doesn't need frequent updates. Has anyone investigated which ham software products work or don't work with Windows set to protected mode?

However, unless there is software based automatic fine tuning, I find that mouse clicking on a signal usually requires fine adjustment with the tuning knob. The advantage of the mouse then is the ability to make large jumps without a lot of knob spinning. That need is sharply reduced by using the RIT knob as a coarse tuning knob.

Another press of the new button, or a number of actions such as moving the main tuning knob, would go back to normal P3 display.

I can think of a lot of reasons somebody might want to upgrade their 
radio, but purely "to have a unit with the latest bells and whistles" 
falls very low on my list, and growing "tired of looking at the same 
radio" isn't on it at all.?? If a new radio offers significantly 
improved utility, great ... otherwise we're sitting at the same table as 
those who buy the newest smart phone every time one comes out simply to 
be able to say they have it.

I say this not as an Elecraft user (although I own a K1, KX2, and 
upgraded K3), but as a consumer who judges a product by it's performance 
to cost ratio.? Upgrades need to provide me with improved utility, not 
simply warm fuzzies that I have the latest.

I received an off list email explaining that ^FS is not included in The KPA1500 command set but may be added later.


It seems the reason it was not included is that the KPA500 Programmer's reference was used as starting point for the KPA1500 command set.  That document has not been kept up to date as new commands have been added.

The KPA500 provides a serial interface command ^FS; which returns the fan speed.   This command is not included in the KPA500 Programmer's Reference but is mentioned in a firmware release note.


The KPA1500 Programming Reference does not mention  the ^FS; command.   Is fan speed interrogation available for the KPA1500?

 About time, thank you Eric, hi.
I contemplated adding to the whines and wishes but decided against it.? I think the quote by an NFL player "for who, for what" crept in my head.
But I guess while I have the space now to make one comment, no matter what is in any radio on my desk, the only thing I have ever needed isthe main tuning knob, the AF gain, sometimes the bandwidth.? That is pretty much it in a nutshell.? As long as I have everything else available I justnever really need or use it.? I operate so2r with the K3 and an FT1000mp 99% in heavy contesting mode.? I have all I want or need in both radios.

Oops!? Ouch!!? I don't use the programming functions yet, but I would 
suggest perhaps farming out the updating of the Programmer's References 
for the K3, K3s, KPA500, and KPA1500 to an interested Elecraft user 
willing to stay right on top of the changes and produce change docs, or 
updated base docs for review/approval by Elecraft proper...

Heck, I might even consider volunteering for the task.

Message-ID: <1637fd36215-c8d-f339@webjas-vac150.srv.aolmail.net>

I think the KPA-1500 is a very nice amplifier and am happy to won one.? That said,?I'd like to see Elecraft find ways to reduce the fan noise, and I believe there are solutions, such as:?in?"Fan 1" mode: rather than have Fan 1 turn on at full speed with full noise,?I'd much prefer to have all 3 fans turn on and run at 1/3 speed as the noise should be reduced while the air flow would be about the same.? When the 3 similarly sized fans on my Yaesu Quadra run at slow speed while the amp is in stand-by or receive mode they are pretty quiet and only generate about the same amount of noise as many desktop computers, and when the Quadra is transmitting the fans go to high speed and produce about the same amount of noise as the KPA-1500 when it's running in the "Fan 2" position.? I imagine Fan positions 3-4-5 are needed because the heat sink in the KPA-1500 is relatively small because the physical size of the amp is small?

 Precisely Dan. I don?t use boat anchors out of the 60s, for the same
reason I don?t own a 60?s TV. I don?t listen to stereos from the 70s, and I
tossed out my 2002 plasma. I am always happy to move forward and forget
living in the past.  And as someone commented earlier. If they are working
on a K4 you might see a teaser from Wayne about 2 seconds before they
announce it. Having said that. I think I have had more fun with the KX2
then the KX3.  Wayne is on to something rewarding with the minimalist
approach. It?s very satisfying.

I have to agree with the posts noting with disappointment that Elecraft
has not, nor seems to show little interest, in producing a new
competitive desktop radio.? That said, I'm sure they are working on one,
but when produced, the market may be saturated with other manufacturers
radios who have felt the need to get to market quickly.

It doesn't matter that the K3(S) is a truly fine and competitive radio.?
It isn't a matter that the performance ratings of the newer radios are
significantly better (they are not).? It comes down to we who love
technology and wish to be on the cutting edge; to have a unit with the
latest bells and whistles.? The K3(S) for the most part, is technology
over a dozen years old.? To wit, I have grown tired of looking at the
same radio for over 10 years, from my early S/N K3 to a second and newer
radio, a K3S.? Ho, hum.

At the price of newer, competitive radios, trading newer for older or
one radio for another becomes less attractive.? I have already seen in
abundance those who have already discarded the K3(S) in favor of Icom's
or Flex's newer offerings, not only contesters but DXers as well. I have
not yet, but may soon.? Should Elecraft come out with a K4 or whatever,
regardless of it's feature set, they've already lost advantage and way
behind the market.? Of course, we who drink the Elecraft cool-aid will
no doubt purchase.

To those that say "moving on" is unnecessary, I ask how old their
vehicles are?? I buy a new vehicle, not often, but every 5 to 7 years
not because the older car doesn't get me from point A to point B in fine
fashion, but because I just want something more recent with newer or
upgraded options.? How about your cellphone? How many are using one 10
years old?? It's personal preference just like it is for radios.

Dan

Regarding my previous post requesting that Elecraft look into ways to reduce the fan noise on the KPA-1500,?I should have stated that I do own good headphones and use them every time I operate.? I'm using Bose Noise Canceling model QC-15.? If you know of a headphone that is comfortable for long contest weekends and reduces noise better than the QC-15 please let me know.

I'm assuming the AX1 but it sounds like Wayne's not going to give away any
more details quite yet.

Hi all ..

has anyone seen this type of issue with their K2.?? Before installing 
the K60XV, I had no problems seeing 10 w on 40 meters.?? After 
installing the K60XV, I can't get above 1 watt on 40 meters OR 60 meters.

Did I screw something up, or is there some menu setting I missed when I 
did the installation?

73s,

In the last few days I have made about 21 Qso's with the new amp casually and about 75 Q's in a few contests over the weekend.? The first night I had a problem that seemedto disappear.? It only happened on 40mtrs.? I was xmitting and the power dropped like I went into stby but no indications on the front panel other than the power LED's showinga power drop.? I chalked it up to maybe not having things setup right as it hasn't happened again.
But tonite I was making some 40 mtr Q's and everything looked normal except the temp was jumping from 6 to 8 degrees low, meaning the temp was climbing normally then itwould fluctuate rapidly down about 6 degrees.? If I stopped xmitting the temp was stabile but xmitting it would jump down and back up quickly.? And now as I'm typing this postthe temp has gone down to normal but the same thing is now happening.? Every time I xmit the temp jumps down about 6 degrees and fluctuates back and forth.
I checked on 20 mtrs and it doesn't happen there so either I've got some rf floating around on 40 or there is a problem in the amp.? I ran the power down and it happens all theway down to about 500 watts out but only fluctuates about 4 degrees.? Just checked on 80 and its OK there.? So will look into this tmrw some more.

Are they 80 or 92mm fans?

You are correct....? You can realize the same volume of air delivery at 
lower noise levels by running 2 or more fans slower. Increasing the 
intake area for the same volume of flow reduces pressure, turbulence, 
noise... lots of cool stuff.? :)

I'm? not sure what the hardware circuit looks like and how much 
flexibility they have for controlling the fans, but this would be one 
way to stave off the noise for a while...

That said,?I'd like to see Elecraft find ways to reduce the fan noise, and I believe there are solutions, such as:?in?"Fan 1" mode: rather than have Fan 1 turn on at full speed with full noise,?I'd much prefer to have all 3 fans turn on and run at 1/3 speed as the noise should be reduced while the air flow would be about the same.? When the 3 similarly sized fans on my Yaesu Quadra run at slow speed while the amp is in stand-by or receive mode they are pretty quiet and only generate about the same amount of noise as many desktop computers, and when the Quadra is transmitting the fans go to high speed and produce about the same amount of noise as the KPA-1500 when it's running in the "Fan 2" position.? I imagine Fan positions 3-4-5 are needed because the heat sink in the KPA-1500 is relatively small because the physical size of the amp is small?

All,

My solution is two 4.5-inch, 48-volt dc muffin fans sitting on half-inch 
tall rubber feet covering the top exhaust vent on amp. They are running on a 
19-volt supply at a slow but effective cooling speed and are very quiet 
(drawing air upward). During normal CW rag chewing the main fans do not come 
on -- a vast improvement for a few bucks. When you go portable, just leave 
'em home.

Message-ID: <69250424.3445582.1526902850045@mail.yahoo.com>

I made some measurements on my K2/K60XV.  It seems the bandpass filter does cut off just above 28.8 MHz and the available 1 mW output from the K60XV drops markedly starting around 29 MHz. It would not be practical to use this output unless the bandpass filter were retuned.  

At the QRP antenna jack, using WSJT (and therefore presumably SSB) the power remains constant (when set for 2 watts) up to at least 29.4, so it seems the power control algorithm is doing its job.  On CW, however, when raising the frequency the power drops.  When starting at 29.4 MHz and going down, the power goes up well above 2 W.  It can be reset to 2 W by moving the power knob off the 2 watt setting and back again.  This isn't very practical in real operation, so once again, the conclusion is that to operate above 29 MHz the bandpass filter would need to be retuned.

 That doesn't move any air across the heat sink or solid state devices that need the air.? The air that comes out of those vents starts at the fans in the rear.

It was a bit surprising to me that the KPA500 fan airflow is the opposite of natural convective flow but I accepted that was the intended design.  My KPA500 fan does pull air in the top and exhaust it out of the back.


"They are running on a 19-volt supply at a slow but effective cooling speed and are very quiet (drawing air upward)."


Do the KPA1500 fans push air into the box? If so, why doesn't the KPA500 fan do that. If the KPA1500 fans pull out of the box why would it be appropriate to use an additional fan that opposes this airflow?

I have a KPA-1500? #171 and when I set the fans at 1 the air is being 
pulled from the back by only the middle fan on? the back. The air is 
exiting out the top cover, front, right.? This exit area is just a 
little over 5" x 8".? I feel a good deal of air coming out the top 
evenly distributed over the 5" x 8" area.

Set at position 2, 3, 4 and 5 all three fans run and the fan speed is 
increased with each setting.? 2 is IMHO is not very noisy, 3 is more 
noise than I like if ran continuously. Sporadically would be OK assuming 
it would not be needed a lot. 4 and especially 5 are noisy.? However I 
would think you would only need 4 or 5 with lots of TX in RTTY or WSJT 
modes so one would not need to be concerned about mic pick up however I 
will say 4 and 5 are not pleasant to listen to.? More to be learned by 
me but I suspect letting the fan be regulated by the temperature rather 
than a fixed setting may be the way to go for lots of TX in RTTY or WSJT.

Anyway the air comes in the back and goes out the top cover on the KPA-1500.

Yes it does, normally air flow is from rear to top. The fans placed over the 
exhaust vent on top create a partial vacuum, drawing in air through the idle 
(or running) fans on the rear apron and out the top just like when the 
regular fans are doing that job.

"Do the KPA1500 fans push air into the box? If so, why doesn't the KPA500 
fan do that. If the KPA1500 fans pull out of the box why would it be 
appropriate to use an additional fan that opposes this airflow?"

Yes, they do...which is also opposite of airflow in K3s. The idea of the 
additional fans is that they are much more quiet than the built ins, even 
when they are on speed #1 . And they prevent the built ins from running so 
much or not at all. Simpleminded, I admit.

 If you are going to depend on those 2 fans sucking hot air out of the amp instead of using the internal fans that push it where it needs to go, I think you arepulling hot air out of the amp and that hot air has already done its damage.

And pulling cool air in, probably through those big holes with fans in them, right where it needs to go. And if the amp gets hot, the built-in fans come on.

So far, all looks good.? My only concern is that the ATU doesn't always 
find a good match, even when the antenna is below 2:1. With the default 
"stop" threshold set to 1.2, it often stops at 1.6:1 or greater.? A 
second tuning sometime helps a bit. Increasing tune power to 20W didn't 
help much. It seems the ATU ought to be able to do better than that with 
a 2:1 load.? Has anyone else noticed this?

That said, integration with the K3 seems to have gone without a hitch.

Seems like if the internal fans don't go on, that means the fan on the top is cooling the amp.

 Feel free to do that with your kpa1500.? While you're at it test how long it takes to reach 60C with and without the modified fan system.I'm comfy with hearing the fans come on and I even set the fan speed to 1 or 2 if I'm in a contest mode.? I don't think there's a thing astoo much cooling for a solid state amp running 1500 watts.? The brief time I've played with mine it doesn't take too long to get to 60Cif you xmit enough.
Good luck.

Roy, contrary to what the other guy said, that is a perfectly logical 
supplement to the OE cooling system.? ANYTHING that reduces the pressure 
at the exit venting will improve airflow over the heatsink.
Increase inlet and exit free area and/or increase inlet pressure or 
reduce outlet pressure.....? all will increase flow volume.

Alternatively/additionally, the industrious owner might also consider a 
custom duct in the back that would provide for adding multiple 120mm or 
140mm high-quality fans set to blow air IN.? I prefer Noctua fans these 
days.? They are quiet, come with anti-vibration mounts built in, and 
there are full anti-vibe gaskets available on some models that prevent 
flow short circuits.? They also come in 3-pin or 4-pin models.? 3-pin 
models can generally be set to run at full speed or at 1 or 2 slower 
speeds.? The trick solution would be to use 4-wire fans and your own 
feedback loop controller to adjust the speed dynamically..... albeit, 
you need to test and modify any of the ready-built controllers to make 
sure you aren't broadcasting RF birdies with the PWM.

The benefit to putting fans in back blowing through the stock 
screen/fans is that you get the slight added benefit of over-pressuring 
the chassis which tends to keep the chassis interior cleaner. Assuming 
adequate rear spacing, you can hide the fans a bit more....

I could go on...? I love thermal control stuff...? I'd be interested to 
see the numbers on how much power/heat is dissipated at 1500W key down...

 Well, I just spoke with Elecraft and it appears this problem was one they had run across in early engineering.? I sent them the config file which might have some indicatorsthey can look at and make some determinations.? But if it turns out to be what the engineer said it might, there might be a fix that is needed to cure this if the temp swing istoo much.

But tonite I was making some 40 mtr Q's and everything looked normal except the temp was jumping from 6 to 8 degrees low, meaning the temp was climbing normally then itwould fluctuate rapidly down about 6 degrees.? If I stopped xmitting the temp was stabile but xmitting it would jump down and back up quickly.? And now as I'm typing this postthe temp has gone down to normal but the same thing is now happening.? Every time I xmit the temp jumps down about 6 degrees and fluctuates back and forth.
I checked on 20 mtrs and it doesn't happen there so either I've got some rf floating around on 40 or there is a problem in the amp.? I ran the power down and it happens all theway down to about 500 watts out but only fluctuates about 4 degrees.? Just checked on 80 and its OK there.? So will look into this tmrw some more.

Yes. and the ultimate is placing them remotely in the closet with a clothes 
dryer hose leading to that plenum sitting at the back air intake coupling. 
Care must be taken so as not to ever restrict air intake to the internal 
fans when they're running at max speed.

There are basically two types of radial blade fans and specific 
application for each one.?? Those that "blow" and those that "suck".? 
There is a difference in the design of the fan blades and the 
application for a specific fan.?? Also some are designed to have "air 
over the motor".? This is a point affecting motor life and bearing

Hi,

This is my first post to this group so if I do something wrong please go
easy on me.

I have a K3s set up at home and I carry a KX3 with me when I travel.

I'll be leaving in just over a week for an extended road trip.

I'd like to get a K3/0 and take it with me to talk to people from my home
qth.

I've downloaded the remote hams server software to my PC and I'd like a blow
by blow outline

of how to connect the K3s to the PC so I can then set up the K3/0 to my
laptop when I get it.

I'll probably take delivery on the K3/0 in a couple of days.

Thanks for any help.

Pete

Subject: [Elecraft] When to use the preamps on the KX2/KX3 vs. K3/K3S
Message-ID: <F749AC0E-C1AC-4973-8847-C8052342C6C7@elecraft.com>

Occasionally we have a KX2 or KX3 user claim their rig has low receive sensitivity. Often this is simply because the preamp is turned off. 

These users may be used to superhet receivers like the one in the K3/K3S, where preamp-off sensitivity (MDS) is typically in the -130 dBm range (or better). The preamp is rarely needed below 15 meters on these rigs.

In contrast, the KX2 and KX3 are quadrature downconversion designs that have the A-to-D converter farther up the signal chain. Even very high-performance ADCs have quite high noise figures, resulting in preamp-off MDS of around -120 dBm. So the preamp is needed more often. Typically, the preamp on the KX2 or KX3 should be used on 20 m and up unless extremely strong interference is present, or if you have a very high ambient noise level. 

Related notes: 

All Elecraft transceivers keep tabs on how strong incoming signals are. If the signals exceed a certain threshold, firmware will automatically turn off the preamp. (This is preceded by a ?HI SIG? warning on the display.)

If signals are so high they might cause damage to the front end--say, a watt or two as measured at the antenna jack--firmware takes the further step of temporarily turning off all of the low-pass filters. This drops the signal level at the receiver?s front end by some 60-80 dB. The actual level of this ?carrier operated relay? function is configurable in some cases (COR LVL menu entry). 

A typical case of this would be at field day, where antennas for two different stations are inadvertently placed extremely close together and one or both are used at high transmit power. The cure is to move them farther apart. The radio will then reenable the normal signal path.

Another case is what we call ?HF Pack Meeting Mode,? where two or more pedestrian mobile operators get their whips crossed :)

Message-ID: <57dd277f-1ac5-1c0d-f765-8b588e49517e@sdellington.us>

After "training" the ATU across part of the band and, I think, setting 
up the K3 so it should track, I notice some strange behavior.? As I tune 
to a different segment of the band, and stop, there's a delay or a 
second or so before the ATU relays switch. Other times, even though it's 
already been tuned to the new frequency, it doesn't switch until 
transmission starts which, of course, garbles the first character.? Am I 
doing something wrong, or have others notice this behavior?? I assumed 
that once the ATU has been tuned to each band segment, it would switch 
as soon as the K3 was tuned to a new segment (if necessary), so it would 
be ready to go when transmission starts.

Bob,


I have made no changes to the cooling of my KPA500.  I also have no idea to what extent the designers of the KPA500 studied the thermodynamics of the design.   I have, however, been surprised at how quickly it heats up.    I abandoned a heating test with the amplifier only producing 100 W output when the PA temperature reached 70 deg C after only 1 minute 45 seconds.  At that point the temperature was close to asymptotic and fan speed was 5 so it may not have gone much higher.


My KPA500 seems horribly inefficient when compared to my TS-590S running a similar power output.  The data for the heating test showed a PA efficiency of 23%, far short of the "approximately 50%" stated in the specification.


I'm willing to share my test data but I know of no means to post it on this stone age "reflector".

Andy:

There are basically two types of radial blade fans and specific
application for each one.   Those that "blow" and those that "suck".
There is a difference in the design of the fan blades and the
application for a specific fan.   Also some are designed to have "air
over the motor".  This is a point affecting motor life and bearing
lubrication.

Those that "blow" are designed to pressurize a box or enclosure to a
specific  pressure measured in inches or millibars of H?O. Reducing the
air exhaust area or restricting air exhaust flow, thus increasing
internal pressure, can cause a blade stall.  This actually reduces the

from a box or enclosure to a specific value measured in inches or
millibars of H?0.     There is always some amount of restriction to
airflow entering, usually being contributed by the obstruction i.e. air
vents,  to air entering the box.  The perforated air vent on top of the
KPA500 as an example.

While I agree that increased airflow is beneficial to keeping

Take care in the application of added cooling efforts.

That's perfectly normal at that low power output.? The 50% spec is at 
full output.? If you ran your TS-590S at 20 W output, you would probably 
see about the same low efficiency.

I generally operate in a fairly low noise environment and little strong  
signal interference.  Still, it is nice to learn the KX2 has such  
safeguards built in, especially since I plan on using mine at a 2 or 3  
station FD operation shortly and been wondering about what effect the SSB  
QRO station next to me will have.  I feel better now.

Great question, I would also like to use one for this purpose. If you're
only using one radio it will get little rest. I am sure that it will
survive a RTTY contest however I would probably set the fan at a higher
continuous speed and live with the fan noise however I wonder how loud
this really is. The initial testers claimed that the amp was very quiet. I
also wonder if the KPA1500 crackles while cooling down like the KPA500.

Yes, if you want to run QRP/battery, you are fooling yourself if you crank ANY * 100 watt radio down to 10 watts out.

Same with, for example, the TS-480, 200 watt version. It's efficiency, even at 100 watts out is barely 25%
The signal is probably cleaner, but the efficiency is shot.

73, Charlie k3ICH

*the K3 is the exception since it bypasses the 100W amp when you go LOW (smart radio eh?).

That's perfectly normal at that low power output.  The 50% spec is at full output.  If you ran your TS-590S at 20 W output, you would probably see about the same low efficiency.

About-

"Take care in the application of added cooling efforts"

Yes, but the proof is in the pudding; watching LEDs display the amp's temp, 
the readings are always cooler with the aux fans running. One reason is that 
between transmissions they continue running and reset the temp back to near 
ambient room temp instead of around 50C where the stock fans shut off. My 
operating is QSK rag-chewing, breaking back forth in round tables. Fans do 
remain off then nearly always. P.S...my 4.5-inch, 48-volt muffins cost a 
whopping $1.86 each! Guess no one wants 48V. If bearings wear out, so what.

Thanks for pointing that out. I did a spot check on the same band with KPA500 indicated output of 490 W (LP-100A 500W) and found the efficiency was 60.6%  (61.9% if LP-100A power is used).

A quick trip to CW then hitting a few dits on the paddle produces the
expected 100w barefoot power.

Then returning to DATA A and TUNE and the expected tune power is emitted.

No idea why this would occur and it is a new thing. I have recently updated
to the latest beta firmware for the enhanced KPA1500 integration. Perhaps a
bug was introduced there?

Ideas?

I have a complete K line with the KPA 500 currently. I am considering
purchasing a KPA 1500. Will the KPA 1500 operate, *on all bands at legal
limit*, while operating as a "run" station in a RTTY contest? That would be
near continuous duty. How loud are the fans when operating in this mode?

Thank you in advance for any information.

Hi guys!

Received my K3S yesterday afternoon and was on the air in about an hour. Made three QSOs with my favorite Net, the OMISS 40m, so everything is working as expected. Tuned around the bands later and listened in on the ANZA DX net from Australia and also heard a guy from New Zealand both on 20m. Couldn?t stay up too late as I have work this AM but was very excited and could have been up a lot longer. Just love being back on the air!

Thanks Elecraft and this group for the support and info. Looking forward to many years behind the mic.

By the way, I opted for just a minimal configuration right now - the ?Casual User? package with the "2.8 filter swap?. Its a K3S with the antenna tuner and 100w amp. Good enough for my current needs.

Those are my near term goals (next two years). One consideration is that whatever I include when I order the K3S will be installed and calibrated by Elecraft at the factory. If I added options later I would have down time and cost of shipping and cost of the work as well (I don?t really want to do it myself even though I did build my first K3).

I've wound up with quite a few of the Handbooks. IIRC, I have ones dated 
'69, '76, '86, and an old hardback version with a red cover from many years 
earlier. I've been trying to decide what to do with them as I don't need all

Wayne,
   Have a KX3 here and use the Rx I/Q Ports with external SDR
receiver and applications need I/Q outputs with an HF 3dB splitter with a DXE RTR-1A
DXE box with Protection from overload Rx protection 


Noticed poor sensitivity due to the High NF when taking output from Rx I/Q at the 
Rx I/Q has great amplitude & Phase Balance ( outstanding ) 


Noted that to increase sensitivity in my Go Box had to add 
a Clifton Labs HF 11dB High IP2/High Ip3 LNA preamp to utilize the
Rx I/Q Ports on super weak Signals.


Found adding an External  Pre-Amp was necessary and with Pre-Amp On in the KX3 for Bands on 
20meters and Higher was necessary to get enough sensitivity for my necessary Rx I/Q 
applications and 3rd Party SDR Synced Receiver being driven by the KX3 and 
WIN4K3 software

Subject: [Elecraft] DSP vs. non-DSP portable transceivers
Message-ID: <C60C8543-20F1-461F-B825-0FE0B3DD9EA3@elecraft.com>

At the Dayton (yeah, OK, Xenia) Hamvention, just before giving a demo of the KX2, a bystander asked me, ?Why would you need DSP in a portable transceiver?? He went on to mention a few currently available rigs he was considering that didn?t have DSP, including one very new one [an ?upgraded? legacy model]. I?ll leave the entire list to the reader?s imagination.

There are two basic reasons to use DSP:

1. As the core of the transceiver?s architecture, to reduce size and weight and increase flexibility

2. To provide a number of important features that have typically been seen only in desktop radios

Explaining #1 is always a bit of a challenge since it dives into theory. Here?s the short version: The receiver in both the KX2 and KX3 uses a high-level quadrature mixer that down-converts the RF signal to baseband (0 kHz) or to a low I.F. (8 kHz). The resulting I and Q signals are fed to a pair of high-performance audio A-to-D converters, and all demodulation is then handled in DSP code. This configuration has immense versatility, reduces component count, and provides very consistent unit-to-unit performance in parameters such as selectivity.

To explain #2, I prefer to just dive into the demo. There's a long list of functions that directly benefit those who operate portable, as well as anyone trying to maximize their communications capabilities.

Here are the DSP functions that I try to include in demos (given enough time), along with their benefits for the operator:

* Multiple Modes

The KX2 and KX3 both support SSB, CW, AM, FM, and several data modes, without the need for supplementary hardware. All demodulation is handled by the DSP. And if we add a new mode in the future, it will be available to all KX-line radio owners free of charge with a simple firmware upgrade.

* Bandwidth Control

The DSP bandwidth can be adjusted from 50 Hz to 4000 Hz (5000 Hz in AM mode). The passband can also be shifted. Rigs without DSP are limited to the passband of their analog filters (including crystal filters). 

* Stereo Audio Effects and Dual Receive

Both rigs demodulate two independent audio channels, allowing for simulated stereo, which reduces listening fatigue. 

Stereo is also used when DUAL RX is enabled; this allows the operator to listen to one signal in the left ear (VFO A) and another in the right (VFO B). This is essential for use with DX stations operating split, and greatly facilitates hunt ?n? pounce contest operation where one receiver is parked on a station to be worked, while the other is used to locate the next one.

* Adjustable AGC

The KX2/KX3 include user-configurable AGC. Threshold, attack, decay, and hold time can all be adjusted. These are parameters that would require dozens of components in a non-DSP design. There?s also a short-duration pulse detector (AGC PLS). When this is turned on--the default--the DSP will seamlessly remove such pulses before they can pin your S-meter and cause a long RX recovery delay. (Rob Sherwood complemented us on this feature, which he found was missing on even high-end desktop transceivers. So, for in-house purposes, we call it ?Sherwood mode? :)

* Noise Blanking

Many non-DSP radios lack noise blanking, or have simple blanking circuitry that can be easily overloaded. The KX-line DSP implements very effective blanking that can take out narrow pulses even at very low settings, and greatly attenuate irregular, high-duty cycle noise sources typical of light dimmers, electric fences, and wideband radar. Blanking can make the difference between a good QSO and not even hearing the other station.

* Noise Reduction 

We often have to deal with stochastic (?white?) noise on the bands. Our DSP-based NR can be adjusted over a wide range to improve intelligibility, especially of speech signals.

* Audio Peaking Filter (APF)

CW operators often have to copy signals right at or even below the noise floor. At times like this, our APF can dramatically improve copy without adding significant ringing. APF uses a special filter shape for this purpose, with a 30-Hz-wide peak and broad, low-delay skirts.

* Text Decode/Encode

DSP allows the KX2/KX3 to demodulate and display CW, RTTY, and PSK31/63 signals directly on the LCD (or in the case of the KX3, as several lines of text on the PX3 panadapter). These modes are also directly supported for transmit purposes, using a keyer paddle (a keyboard can also be used, in conjunction with KX2/3 Utility and a notebook computer).

* Receive and Transmit EQ

8-band EQ is provided to allow the operator to tailor both receive and transmit audio to meet special hearing requirements, optimize for use with particular microphones, etc.

* CWT (CW/data tuning [auto-spot] and mini-spectral display)

The DSP sends the MCU information about how far off the nearest signal is from the user?s selected sidetone or mark tone frequency. We use this to enable quick, one-tap auto-spotting of signals, as well as to drive a 10-segment bar graph that shows the signal?s position in the filter passband. 

* AF Limiter

Some operators prefer to turn off AGC and control gain manually. This eliminates the ?signal flattening? effect of AGC, instead emphasizing the amplitude dynamics among multiple signals. When AGC is off, DSP provides an adjustable-threshold AF limiter to protect your ears when very strong signals appear (AF LIM menu entry).

* Special Transmit Features

The KX2/KX3 include very effective adjustable speech compression, variable-threshold VOX and anti-VOX, and transmit noise gating. All three can be used to improve effectiveness of speech modes in noisy outdoor conditions.

There?s also a two-message digital voice recorder that takes advantage of the DSP?s large flash memory. DVR message play can save your voice when you need to repeatedly call other stations. This is especially likely when running QRP and/or using compromise field antennas.

I?m pretty sure that the bystander in question walked away with a KX2, post-demo :)

Neil,

Did you set the secondary menu D19 parameter to "Y"?

If you have the KAT2 installed, be certain the change KAT2 R6 to 470 
ohms, there is a resistor provided in the K60XV kit for that.

My very first ARRL Handbook was 1960.  My last, until the modern era, was 1966.  Although I no longer have the originals, I have bought copies in pristine condition at hamfests and they sit right next to my original 1966 Allied Radio Catalog with the order form sheet still in it ready to be used.

Decades ago, a good friend who was a Royal Lao Air Force officer asked 
me if I would assist his daughter with English in preparation for her 
secondary school admissions examination.? I realized early on that I was 
heading for failure while we were on formation of plurals ... dog/dogs, 
cat/cats, person/people, goose/geese, moose/moose, sheep/sheep, ...? The 
Lao language has no plurals so we were starting from scratch.? It was at 
least an order of magnitude harder than O Chem and we hadn't even gotten 
to "i before e ... or not, you choose."

So I purchased a KX3 kit recently.  It arrived and I carefully built it.  I
have a well equipped workbench with all the proper tools and instruments
for doing small electronic work as I design a lot of stuff.

My KX3 worked on receive right the first time, but wouldn't transmit.
After many emails back and forth (on a weekend no less!!) from Wayne and
the crew, it was decided I needed to send it back.  I did so and Joe worked
on the unit.  He found a *demolished* surface mount capacitor on the
control board.  I unpacked my parts from bubble wrap directly onto the
static mat at my workbench and used all the appropriate tools to assemble
(ie, nutdrivers for standoffs, not pliers, etc!!).  I know I didn't cause
the damage.

But, how would they know that?  When Joe called me and then emailed me a
picture, I thought... I'm in for it. There is no way they are going to
believe me that I didn't damage it.  Well, I didn't have to.  Joe didn't
even ask.  He just fixed it under warranty and said "don't know how or when
it happened, we just want you to be happy with your purchase"

This is not the customer service I've become accustomed to with any
vendor!  Huge kudos to the owners and employees of Elecraft.  This kind of
treatment as a customer is unheard of in today's world and I can't say
enough good things about the experience.  Nothing is perfect, eventually
something will sneak by and these guys not only stepped up to the plate,
but went above and beyond to make it right, and make it right FAST!

Thank you all very much.  I appreciate all the help and wanted the group to
know ( I suspect this isn't new news to anyone on this list!!) that
Elecraft has made a new customer out of me that will definitely be a
repeat!

Thanks for taking the time to read this.  It was important to me to
publicly pass my thanks on to these guys!!  Wish more companies were like
this!

Here?s the short version: The receiver in both the KX2 and KX3 uses a high-level quadrature mixer that down-converts the RF signal to baseband (0 kHz) or to a low I.F. (8 kHz). The resulting I and Q signals are fed to a pair of high-performance audio A-to-D converters, and all demodulation is then handled in DSP code. This configuration has immense versatility, reduces component count, and provides very consistent unit-to-unit performance in parameters such as selectivity.

Hi Buck,

I?m not entirely sure how to parse your response to my posting. But I can cover several possible interpretations by pointing out that the K3S has all of the same DSP features as the KX2/KX3, and then some. The K3S also has the advantages of a superhet, with narrow crystal filters in the 1st IF protecting the ADCs.

The P3 panadapter, meanwhile, is actually a direct-sampling SDR, with its own DSP. It taps off the 1st IF, which is protected by the K3?s marrow RF band-pass filters. The P3?s noise floor is extremely low because it is also preceded by the K3?s preamp, LNA, and low-loss mixer.

Here?s the short version: The receiver in both the KX2 and KX3 uses a high-level quadrature mixer that down-converts the RF signal to baseband (0 kHz) or to a low I.F. (8 kHz). The resulting I and Q signals are fed to a pair of high-performance audio A-to-D converters, and all demodulation is then handled in DSP code. This configuration has immense versatility, reduces component count, and provides very consistent unit-to-unit performance in parameters such as selectivity.
>> To explain #2, I prefer to just dive into the demo. There's a long list of functions that directly benefit those who operate portable, as well as anyone trying to maximize their communications capabilities.

>> * Multiple Modes
>> The KX2 and KX3 both support SSB, CW, AM, FM, and several data modes, without the need for supplementary hardware. All demodulation is handled by the DSP. And if we add a new mode in the future, it will be available to all KX-line radio owners free of charge with a simple firmware upgrade.
>> * Bandwidth Control
>> The DSP bandwidth can be adjusted from 50 Hz to 4000 Hz (5000 Hz in AM mode). The passband can also be shifted. Rigs without DSP are limited to the passband of their analog filters (including crystal filters).
>> * Stereo Audio Effects and Dual Receive
>> Both rigs demodulate two independent audio channels, allowing for simulated stereo, which reduces listening fatigue.
>> Stereo is also used when DUAL RX is enabled; this allows the operator to listen to one signal in the left ear (VFO A) and another in the right (VFO B). This is essential for use with DX stations operating split, and greatly facilitates hunt ?n? pounce contest operation where one receiver is parked on a station to be worked, while the other is used to locate the next one.
>> * Adjustable AGC
>> The KX2/KX3 include user-configurable AGC. Threshold, attack, decay, and hold time can all be adjusted. These are parameters that would require dozens of components in a non-DSP design. There?s also a short-duration pulse detector (AGC PLS). When this is turned on--the default--the DSP will seamlessly remove such pulses before they can pin your S-meter and cause a long RX recovery delay. (Rob Sherwood complemented us on this feature, which he found was missing on even high-end desktop transceivers. So, for in-house purposes, we call it ?Sherwood mode? :)
>> * Noise Blanking
>> Many non-DSP radios lack noise blanking, or have simple blanking circuitry that can be easily overloaded. The KX-line DSP implements very effective blanking that can take out narrow pulses even at very low settings, and greatly attenuate irregular, high-duty cycle noise sources typical of light dimmers, electric fences, and wideband radar. Blanking can make the difference between a good QSO and not even hearing the other station.
>> * Noise Reduction
>> We often have to deal with stochastic (?white?) noise on the bands. Our DSP-based NR can be adjusted over a wide range to improve intelligibility, especially of speech signals.
>> * Audio Peaking Filter (APF)
>> CW operators often have to copy signals right at or even below the noise floor. At times like this, our APF can dramatically improve copy without adding significant ringing. APF uses a special filter shape for this purpose, with a 30-Hz-wide peak and broad, low-delay skirts.
>> * Text Decode/Encode
>> DSP allows the KX2/KX3 to demodulate and display CW, RTTY, and PSK31/63 signals directly on the LCD (or in the case of the KX3, as several lines of text on the PX3 panadapter). These modes are also directly supported for transmit purposes, using a keyer paddle (a keyboard can also be used, in conjunction with KX2/3 Utility and a notebook computer).
>> * Receive and Transmit EQ
>> 8-band EQ is provided to allow the operator to tailor both receive and transmit audio to meet special hearing requirements, optimize for use with particular microphones, etc.
>> * CWT (CW/data tuning [auto-spot] and mini-spectral display)
>> The DSP sends the MCU information about how far off the nearest signal is from the user?s selected sidetone or mark tone frequency. We use this to enable quick, one-tap auto-spotting of signals, as well as to drive a 10-segment bar graph that shows the signal?s position in the filter passband.
>> * AF Limiter
>> Some operators prefer to turn off AGC and control gain manually. This eliminates the ?signal flattening? effect of AGC, instead emphasizing the amplitude dynamics among multiple signals. When AGC is off, DSP provides an adjustable-threshold AF limiter to protect your ears when very strong signals appear (AF LIM menu entry).
>> * Special Transmit Features
>> The KX2/KX3 include very effective adjustable speech compression, variable-threshold VOX and anti-VOX, and transmit noise gating. All three can be used to improve effectiveness of speech modes in noisy outdoor conditions.
>> There?s also a two-message digital voice recorder that takes advantage of the DSP?s large flash memory. DVR message play can save your voice when you need to repeatedly call other stations. This is especially likely when running QRP and/or using compromise field antennas.

Yes. AND in the hands of a knowledgeable engineer/technician, a near 
lab-quality test instrument, with a display that can easily be 
calibrated to the signal level at the antenna input. I've used it to 
measure occupied bandwidth of transmitted signals to precision of a few 
Hz, and the SVGA board, with it's separate, higher res FFT, improves 
that to one Hz. I own two other dedicated spectrum analyzers -- an HP 
8657A and a Rigol. They are not capable of these measurements, because 
they lack the frequency resolution (by a factor of about 500:1).

Many other modern SDRs also have this capability when used with suitable 
software.

My 1st was a 1957 given to me as a XMAS present by my grandmother.  In pretty 
sad shape now but I still have it.  My 1st rig setup was all Heathkit, AR3 
receiver, AT1 transmitter and AC1 antenna coupler.  Not the original but I have 
them all now.

However there is a radio piece I've been looking for for years now.  So this is 
a WTB request too.  My 1st piece of radio gear was a Boy Scout Radio kit.  It is 
shown here on page 69:

https://books.google.com/books?id=7lafwNQ6mREC&pg=PA8&lpg=PA8&dq=bsa+explorer+radio+kit&source=bl&ots=Meh1Q3jEQ-&sig=7Ctm006UedcN738sZnpPP_mTTEg&hl=en&sa=X&ved=0ahUKEwiU07Xirf7YAhUK44MKHWjTDXIQ6AEIYzAN#v=onepage&q=bsa%20explorer%20radio%20kit&f=false

Anybody have one or clues to a potential source?

This was also a XMAS present and that lead to Ham Radio and eventually to my 
career in electronics and TV broadcasting.

Also have a birthday year Handbook, 1942.

In advance, TNX!

When the IBM Selectric was the top of the line in the 60s and 70s, a rumor went around that there was available on the aftermarket a character ball with a "blur key."  It would imprint on the page what looked like an accidental illegible smudge.  To avoid making an embarrassing mistake with the i and the e, one could just hit the blur key twice.  I don't know if the rumor was true or baloney (bologna?), but it was a classy idea.

Meanwhile, eerie is often a good substitute for weird.  I would have suggested bizarre but who can remember how many Zs and Rs there are?  Sort of like Cincinnati . . . .

============
I've tried to teach English to students from 19 different countries,
although not Laos. No matter what the student's native language, it's an
uphill battle. But the strong incentive to learn English is the driving
force that eventually gets over many of the obstacles -- although
"eventually" can be a long time and "many" can be a pretty small number.

Ted,

Until I got my EE Degree, I was a technician in IBM's Typewriter 
division, and I worked on customer's premises for Selectrics as well as 
typebar machines (and dictating equipment).
I can tell you that there was never a "blur" character on the typeball, 
nor a "blur key" on the keyboard for any of the machines.  There WAS a 
lot of talk about it in certain circles, and a desire on the part of 
many operators for such a blur key.

It would imprint on the page what looked like an accidental illegible smudge.  To avoid making an embarrassing mistake with the i and the e, one could just hit the blur key twice.  I don't know if the rumor was true or baloney (bologna?), but it was a classy idea.

I assembled my PX3 kit over the weekend and the screen is not displaying
properly.

It's almost as if the contrast is set way too high (if that's possible).
>From head on almost nothing is visible (it just looks like a white screen),
but from certain oblique angles you can just make out the spectrum display
and read the menu entries, etc. I installed the latest firmware and played
around with the brightness, but there's obviously something wrong. Other
than the screen the unit appears to be functioning correctly. I was able to
pull a "screen capture" using the PX3 utility and it tracks my KX3
frequency as it should.

I was thinking the ribbon connection to the screen needs reseated, but
maybe it's just a bad display.

Has anyone ever had this issue before? I emailed support a couple days ago
but haven't gotten a response.


Thanks,

Joe, N3XE

Message-ID: <b9467a5d-020d-b8f4-3f1c-76ae6485a0eb@gmail.com>

I am putting my KX3 station up for sale; its seems that my KX2 has 
replaced it in the portable use, and I just move my k3 to the other 
shack when I go there...

The station is operating perfectly, no smoking environment, very clean 
appearance; it has the following items:

    *KX3**-F* (factory built) serial number 0620; has handle style side
    plates, external HD heat sink and associated accessories below: *
    *

        *KXAT3* internal antenna tuner *
        *

        *KX3-2M-AT *internal 2m module to fit with antenna tuner installed

        *KXFL3* Internal Dual-Passband Roofing Filter

        *KXBC3 *Internal NiMH Charger / Real-Time Clock

    *PX3-F *Panadapter for KX3; Assembled*
    *

    *KXPA100-F *100 W External Amplifier-Factory Assembled *
    *

    *KXAT100* Internal Auto Antenna Tuner*
    *

    *KXPACBL *KX2 and KX3 to KXPA100 Integrated Adapter Cable

You will see that if you add them up new (not counting the external heat 
sink and end plates), before shipping you come to $3,739.55.

I would like to get $2,500 for it, shipping and insurance prepaid, 
within the US; PayPal preferred.

Please email me direct for inquiries; I can provide photos for serious 
inquiries, and if requested will provide my phone number off list.

Thank you for the bandwidth.

Message-ID: <201805222245.w4MMjNCM014664@mail42c28.carrierzone.com>

Just to add a little info, I measured and compared my KX3-SN475 to my 
K3-SN4043:
http://www.kl7uw.com/HF.htm  Half-way down the page.

KX3 on 6m with preamp on was -127 dBm with 2.8-KHz SSB*
K3 on 6m with ARR Gasfet preamp was -137 dBm*
on 10m the K3+PRE outperformed the KX3, as well

Subsequent to this testing I acquired a PR6-10.  I helps the K3 
tremendously but not quite as much as using the ARR preamp**. 
Subjective impression is the PR6-10 equals the KX3 in MDS.
*Add 7.5 dB for MDS at 500-KHz bw
** Uses mgf-1302 GasFet with 0.5 dBNF and 25 dBG

I don't own a KX2

I'll try that, but I suspect the delay in switching the ATU will 
persist.? I'd like the option to turn off that delay, so the beginning 
of my call isn't cut off.

Mine does this on 6 meters if SPLIT is enabled. Turning SPLIT off and 
then pressing TUNE it will put out power.? Turn SPLIT back on and TUNE 
will put out full power until the next power cycle of the radio.? 
Strangely, it only happens on 6 meters.

I posted about it here before and was told it was probably an issue with 
WSJT-X which doesn't make sense because the radio behaves this way 
without WSJT-X even running on my computer.? I don't know how WSJT-X 
could change the K3 firmware.

Jim - in this context, are you using the definition of "occupied
bandwidth" as in ITU RR 1.153, i.e. 99% mean power? If so, how do you do
that with the P3 SVGA?

Although I've not experienced this, with or without having run WSJT-X, I 
have experienced some software applications which do not correctly 
terminate and thus my leave an erroneous? command in the radio.??? This 
can happen if the software application is running or open and the radio 
is powered down before the software application is closed.? This command 
may still be resident even after a power cycle of the radio.?? I have 
always found it best to close any and all of the software application(s) 
before powering down the radio.? Having done this, most will make a 
clean exit.

One of the topics I've discussed with with noted engineers has to do 
with use of a Preamp and use of the Attenuator and use of the RF Gain 
control. ? In general the optimum legacy receiver performance occurs 
when the receiver noise floor is some 10 db below band noise.? Being 
such,? how does one attain this?? If the no signal band noise is S-5 or 
-97 dBm, and receiver noise floor is -133 dBm {i.e K3S}, this says one 
should use a combination to total? 26 dB Attenuation and RF Gain 
reduction. ? Certainly one would NOT want to have a Preamp engaged under 
these conditions. Likewise, if the band noise is -121 dBm or about S-1 
and the receiver noise is -138 dBm? {Preamp engaged} one might wish to 
reduce the RF Gain a bit.

 From experience and my observing other hams operations, many seem to 
think more gain is needed to hear or pull out weak signals from the 
noise.?? I find the proper use of the Preamp and specially the correct 
amount of? Attenuation and RF Gain reduction, weak signals seem to pop 
out of the noise.

Whilst it's not completely accurate, it is very easy to approximate
the "occupied bandwidth" of reasonably strong signals using the P3.
Set average to maximum and look at the points 20 dB down on either
side.  This will over estimate the bandwidth of a signal depending
on the peak to average ratio of the given modulation (e.g., level of
clipping of an SSB signal) but still provides a useful first order
approximation.

The greater difficulty is in measuring the occupied bandwidth of very
narrow modes (e.g. JT65, JT9, FT8, RTTY or even CW) due to the 2 KHz
minimum span of the P3 ... a 500 Hz span would be better for measuring
narrow modes.

To put it mildly, with progress in computing, the implementation in DSP is
easier, smaller, cheaper and mostly better. Programming is expensive. 

Same with tube and SS amplifiers. Most likely, hardware-wise SS is easier,
cheaper and mostly better. Initial design and programming are expensive.   

Average age of ham radios is around 65 (QST). Old "truths" die slowly.

The problem with simply reducing the gain is that the AGC may become 
ineffective, forcing the operator to increase audio gain on weak 
signals.? Then the strong signals can be loud enough to be 
uncomfortable, or even cause hearing damage.? I like to keep the gain 
high enough to get some AGC action on the weakest signals, and reduce 
"RF Gain" when necessary to distinguish stronger signals from weaker 
ones. "RF Gain" in modern receivers really just sets the maximum gain 
the AGC will allow, so reducing it only attenuates weaker signals.

That said, turning off the preamp and/or enabling the attenuator should 
be necessary only if strong signals are causing overload. Of course, if 
the receiver has enough gain for a low enough noise floor and good AGC 
operation on weak signals with the preamp off, there's no advantage in 
using it.

Are you also getting temp fluctuations in xmit and how much?? Mine is dependant on the temp, at lower temps the fluctuation is less than if up at 60Cand mine only happens on 40 mtrs.? Spoke with an Elecraft engineer and this could possibly result in a mod surrounding the temp sensor.

I have been playing with some SDRs and the IF out on the K3.?? My SDR is 
about 8ft from the radio, hence I am using about a 10ft coax cable from 
the IF Out to the SDR.

I got to wondering if the cable length is of any concern?

I would think not (at least at 10ft), but there are a bunch of smart 
folks on this list, so I thought I would throw the question out to the 
masses.

BTW - The setup is working fine.? I am just curious.

Mark,

Are you using the USB cable to connect the K3S to the computer?  If so, 
do you have the CBLP3Y cable connected between the K3S RJ-45 jack and 
the P3 RS-232 connectors?  If you do have that cable, make certain the 
RJ-45 plug is fully inserted.  You may have to pull back the cover and 
push the metal part of the plug in completely - it must snap in.

If you do not have the CBLP3Y cable, you can use the RJ-45 to RS-232 
cable that comes with the K3S to connect to the P3, but you must set the 
K3S menu to RS-232 rather than USB (use 38400 baud).  Connect to the PC 
from the RS-232 connector on the P3.

As I said before, you have to have the serial connection between the P3 
and K3 functioning for fixed tune to work.? It has nothing to do with 
the BNC jumper from the 1st IF out.? If that's bad, the P3 screen will 
flat-line.

I have an A-B data switch in my serial cable.? When operating locally, 
the connection is PC --> P3 --> K3, and fixed tune works fine.? When 
operating remote to W7RN, the switch moves the K3 serial port to the 
RemoteRig RRC-1258, and the P3 is removed from the serial path.? It then 
shows "0" at the top center, and +/-10 at the edges [span is set to 20 
KHz], and of course, the cursor does not move when I tune.

The P3 is still on, looking at the 1st IF signal from my local K3 at 8 
MHz, and the K3 receiver, up to the first IF out, is still functioning 
on whatever band/frequency I was last on locally.? I can put the K3 on 
14030, go to the remote and transmit on 14030 and I will see myself from 
W7RN on the P3, and I can see the stronger signals around that 
frequency.? My local antenna is an HOA-compromise, and I don't see 
nearly as many as I can hear on the remote where the coefficient of 
aerial aluminum is very high, however.

I really miss the P3 when operating remote.? A K4 seems to be at the top 
[or perhaps the only thing] on everyone's list.? That may or may not 
exist, now or ever.? If Elecraft is looking for a new project, how about 
an accessory for the host station that will put the P3 and it's controls 
onto a 2-way TCP/IP stream and an accessory for the control station P3 
that will take that stream and pretend it's actually connected to the 
1st IF out in Virginia City Highlands.

Now, before everyone positions the mouse over "Reply to List" to tell me 
that there are products on the market that will stream the P3 video down 
to my PC, save the BW, I already know that.? There are controls on my 
local P3 which also need to work for the P3 to be useful.? And, I'm 
fairly addicted to Elecraft's definition of "system integration."? Come 
up with an "Elecraft-solution" to this and I'll buy S/N 1 for the 
station and myself.

Does a 100w amp ADD to your radio's output, or push it to 100w?

Asked another way, if I have a 100w radio set to full power, does a 100w
amp make output 200w, or does it stay at 100w?

An amplifier boosts your radio's output power to the maximum power of 
the amp. A 100 watt amplifier will put out a maximum of 100 watts (or 
thereabouts). It does not add 100 watts to whatever your radio is 
putting out.

Richard -

There are probably more technical responses than this, but I think the
simple answer is that if you have a 100W Solid State amp, and drive it with
100W you will likely either destroy something, or the system will self
protect and shut down. I know that with my K3 and KPA500 combo, I get 500
watts out with about 28 watts from the K3... if I raise the output power of
the K3 to a bit above 30 watts (maybe 32 or 33w), the amp 'faults' because
of excessive drive, so my 500 watts amp gives me 500 watts when driven by
an appropriate amount of RF. If it is additive, I am not aware of it.

I believe the answer is somewhat different if using a tube type amp in a
grounded grid configuration.

Scott,

If the weakest signals are already activating the AGC, that's the exact condition that leads to the many 'my K3 is noisy' complaints that we see here. Plus, that tends to make all signals sound like they're the same strength, another complaint we've heard in the past.

In fact, you don't want weak signals activating AGC. You want strong signals, above a certain threshhold (AGC THR on the K3) to activate it.

This gives you a nice, quiet linear region where weak signals sound weak, and stronger signals sound stronger.


In addition, overload should not determine whether you turn off the preamp! That's way bad advice.

Here's the general principle: you should only use as much gain as you need. AF as well as RF. Less is usually better. Your ears will not be blown by reducing your receiver gain.

R,

Contrast your experience, James, with what happened recently when I purchased a kit on eBay from a seller in a country that now has the NSA observing me closely for collusion. When I emailed to tell the seller that two critical parts were missing from the kit, he replied that that was "rubbish" and told me flat out I didn't know what I was doing. Can you imagine Elecraft ever doing that? I can't either.

In the K3/K3S/KX2/KX3, "RF Gain" adjusts receive path gain ahead of the 
AGC detector while "AF Gain" adjusts the receive path gain AFTER the 
AGC, if any, is applied.

Hi Ed,
?
Thanks for all the RTTY Qso's!
?
I read your post on the Elecraft reflector with interest.? I have two different sets of Bose QC-15 noise canceling headphones, and when I use either one, and running on CW or RTTY, the fan noise from my KPA-1500 is loud and annoying when the Fan hits level 2, and extremely loud and extremely annoying when the Fan it hits level 3.? It's hard for me to copy CW signals when the Fan hits level 3 and extremely difficult to receive when the Fan hits level 4.? ??
?
Many people have complained that the Yaesu Quadra has noisy fans when transmitting and running at full speed, the fan noise from my KPA-1500 is louder at Fan level 2 than my Quadra fans are when operating at full speed.? Also, when the KPA-1500 fans are at Level 2 the noise bleeds through my noise canceling headphones louder than the fan & blower noise from my Alpha 8410.
?
So either your noise canceling headphones work better than mine or your "field-test" KPA-1500 is a quieter than my production model.? Please advise what type of noise canceling headphones your using?
?
Thanks & 73,
Dick- K9OM

Anecdotally,? I've operated several RTTY contests with a field-test KPA1500 and it just loafed along.? I didn't critically examine fan noise.? With noise-canceling headphones,? I wasn't aware of any fan noise.? Operationally, it felt like QRP, Wayne's target environment.?

Hi,
   The SVGA schematics were missing at
http://www.elecraft.com/manual/P3_svga_D_sch.pdf...
I was trying to see if the 5 Vdc was available at the keyboard port to
drive a SVGA to HDMI converter or if it needed to be turned on in software.
I could not find this information in the manual.

Other than not having power, plugging the video adapter in did not seem to
affect the operation of the P3, and when I plugged the adapter into a USB
power adapter, I got the full display on the monitor.  I'm looking at using
a split screen at an upcoming special event...

For CW, I transmit a long series of dits, put the P3 in peak mode, and 
accumulate peaks. When the display stops changing, I freeze it, use the 
cursor to manually log enough points to define the curve on both sides 
of the carrier, starting at -20dB carrier and every 5 dB until the data 
falls off screen. I then save the screen to a file.

I've done essentially the same thing with RTTY and PSK.? For SSB, my 
test signal is bandwidth limited Pink Noise. Pink Noise is widely used 
as an audio test signal because both spectral balance and dynamics are a 
good first approximation of speech. Pink Noise is defined as equal power 
per percentage bandwidth, whereas white noise is equal voltage per Hz. 
Pink noise can be though of as white noise with a 3dB per octave 
rolloff. That's not easy to generate -- an RC rolloff is 6 dB/octave.

And this important comment. NC0B uses White Noise as a source. This is 
VERY BAD practice, because it puts nearly all of the modulation above 
the voice spectrum, and greatly de-emphasizes speech. I've corrected him 
on this three times, first as long as five years ago, yet he continues 
to do it wrong. The importance of this is that GOOD audio processing is 
designed for the spectrum and dynamics of speech, so any audio test 
signal should approximate speech as closely as possible. Rob is a great 
engineer and does ham radio a great service with his testing, but he 
fails to even attempt to understand the difference between RF and audio.

As to my credentials to say this -- I spent 40 years in pro audio, with 
much of my work directed to sound systems for both speech 
intelligibility and music. For 20 years, I've been a member of the AES 
Standards Committee, and of Working Groups on Speech Intellibility. 
About ten years ago, I was elected a Fellow of the AES.

Not so difficult at all, using the methods I outlined in a previous 
post. I have successfully used it on RTTY, CW, PSK31 an a steady 
carrier. Most of that data is summarized in this Power Point pdf. Most 
of these data are from the SVGA.

http://k9yc.com/P3_Spectrum_Measurements.pdf

Note -- TXEQ in my K3s are set maximum rolloff of the 50, 100, and 200 
Hz octave bands and some rolloff of the 400 Hz band. This accounts for 
the difference in the shape of the top of the curve between my K3s and 
other rigs tested.

I make a deliberate choice to set the AGC threshold low, so I DO get AGC 
action on weak signals. Perhaps my ears just don't have the dynamic 
range they used to, but I find otherwise the strong signals are just 
uncomfortably loud.? Yes, I have to ride the RF gain to distinguish 
signals of different strengths, but I find that a fair trade-off.? Give 
the average age of hams these days, I doubt I'm the only one with such 
issues.? Of course, younger operators may want to treat their ears 
gently, to preserve that good dynamic range.

Note that high acoustic background noise can further reduce the 
difference between audible and painful.? The Radiosport headset is the 
best remedy I've found for that, short of putting the amplifier in 
another room.

My K3S does this on all bands regardless of wheter it has been power
cycled.  Pressing the tune button while split in data mode keys the
transmitter but produces no output.  Do nothing else but cancel split
mode and pressing tune will then key the transmitter and produce normal
tune output.  I thought it was a strange feature ...

When using DATA A or AFSK A, you are normally working from a waterfall 
display, and the computer application software can work SPLIT.  I do not 
see the need to operate SPLIT using VFO A and VFO B, but someone can 
enlighten me to why that is useful.

A different situation exists for those using FSK D, but I don't think 
that is what is being discussed.

Simple logic. One should (is supposed to) listen on the frequency before transmitting.  Can't do this if one is configured to receive on a different frequency.

Don,

I have everything setup as shown on page 6 of the P3 manual. I am using the serial cable with the RJ-45 jack.  All connections appear tight. I am wondering if there are any setting on the K3S that need to be checked or set. Both the K3S and P 3 are brand new. The K3S is loaded with all available options except the 2 meter band option.

Thanks,
Mark

If you do have that cable, make certain the RJ-45 plug is fully inserted.  You may have to pull back the cover and push the metal part of the plug in completely - it must snap in.

Have you tried doing a P3 reset as described on page 45 of the manual?  If that doesn?t work, I?d suspect the control cable from the K3S data connector to the P3 first.  Of course, there could be some other hardware problem in either box.

Elecraft support can probably walk you through troubleshooting.

Almost, but not quite. Assuming the amplifier is linear (as are the Elecraft units), the amplifier will boost the signal by the multiplication factor of the amp, up to a maximum value.
For example, the KPA500 has about 13db of gain, so the output will be 13db above the input, up to about 700 watts. To put it another way, if 40 watts input gets 500 watts out,
then 4 watts in will give 50 watts out. There is a maximum input level for each amplifier (I believe 60 watts for the KPA500, but would have to check), and a maximum output value.

Don?t expect that any input will drive the amplifier to full output, but the output is indeed proportional to the input.

Hope this helps!

Don,

WSJT-X has a feature that uses SPLIT to keep the audio frequencies in a 
more usable range.? For example if someone is calling CQ at 300 Hz on 
the waterfall, instead of trying to transmit a 300Hz audio tone, WSJT-X 
will tune VFO-B down 1 KHz, enable SPLIT, and transmit a 1300 Hz tone.? 
I find that this keeps me from having to re-adjust the audio levels when 
operating near either end of the waterfall. Working SPLIT like this 
keeps your TX audio between 1500 and 2000 Hz.

Is the tuner range of the K-3 and the KAT-500 the same?
They seem to tune the same antenna differently, (of course the K-3 is tuning through a bit more coax with both the KAT-500 and KPA-500 on standby.)
They are tuning a 250? Doublet via a short coax run (10?) to an external 4:1 current Balun, then via true 600 ohm open ladder line. 
(I tried a 1:1 Balun, but it did not have as great a range on 160 as using the 4:1.)
The K-3 seems to have a bit more range than the KAT-500.
Is that to be expected?

Mark,

Using the cabling shown on page 6 of the P3 manual, you must connect the 
computer to the P3 with an RS-232 cable or USB to serial adapter (not 
the K3S USB cable).
Also set the K3 menu RS-232 parameter to 38400 and NOT USB.
Be certain the P3 is also set to 38400 baud.

Again, pull the boot on the RJ-45 dongle back and push on the metal part 
of the plug to make certain it is fully seated.

If you switch to the K3S to computer USB cable, you must use the CBLP3Y 
cable between the K3S and the P3 as shown on page 5 of the P3 manual.

Don W3FPR

I believe that the K3 tuner does have more range than the one in the KAT500.

My experience with this kind of system (tuner -> balun -> open wire 
line) is that the 1:1 balun works much better from the point of view of 
losses and choking off RF in the shack.

What do you mean that the 4:1 balun has less range on 160 than the 1:1? 
If you are saying that the SWR curve is broader, then that could just be 
because of losses in the balun.

GPS Distibution Amp (HP 58516a/HP58517a Unity Gain Distro Amp) ports not

Output ports on GPSDO and NTP servers (10MHz and PPS)?
Others?

Or are some/all of them self terminating?

Don,

Problem corrected. The K3S was set to the wrong baud rate.

Good Morning,
I have been looking and without success been able to get the K3 to TX on

Will,

Does the K3 go into transmit?  If so, set the audio levels correctly. 
You must achieve 4 bars solid on the ALC meter with the 5th bar 
flashing.  There are guidelines for doing that on my website www.w3fpr.com.
Scroll to the bottom article in the left column and click on the link.

You're right, sorta. I didn't try it on all bands, but it happens on 6-meters 
but not 10-meters. Power cycling puts it back in this mode.? If you re-enable 
Split after a non-split tune where it does put out power, then go back to Split 
it will tune.

I wouldn't call it a feature, I'd call it a bug.

"Simple logic. One should (is supposed to) listen on the frequency before transmitting. Can't do this if one is configured to receive on a different frequency. "


Sorry, but that's a very "old school" way of thinking. With digital modes that use VFO split operation the usual way to check if the TX frequency is free is to look at the waterfall. I watch a 4-5 kHz span when operating WSJT-X modes with split VFO and never have any need to "listen" on the the TX VFO frequency to know if my TX signal will overlap another signal.


In any event, my TS-590S always "tunes" the TX VFO frequency whether spit or not and whether DATA mode or not. if I want to listen on the TX VFO frequency I just press TFSET to swap VFO.

I wouldn't say they were self-terminating, but more that they don't care.? If 
you have a multi-port passive splitter then I would terminate unused ports to 
ensure proper splitting.? Maybe your GPS distribution amp too as it may be an 
amp driving a passive splitter inside.

Why does it matter the need?? It's strange behavior and apparently inconsistent 
between different radios.? Besides FT8 Split does use the radio split feature 
although it's unrelated to this issue.

I believe they are the same, the difference noted is due to the different paths to the antenna. Wayne answered this question for me a couple years ago.

Is the tuner range of the K-3 and the KAT-500 the same?
They seem to tune the same antenna differently, (of course the K-3 is tuning through a bit more coax with both the KAT-500 and KPA-500 on standby.)
They are tuning a 250? Doublet via a short coax run (10?) to an external 4:1 current Balun, then via true 600 ohm open ladder line.
(I tried a 1:1 Balun, but it did not have as great a range on 160 as using the 4:1.)
The K-3 seems to have a bit more range than the KAT-500.
Is that to be expected?

My findings and applications agree with Victor's statement that a 1:1 
current balun, specifically a Guanella balun design with added common 
mode choke is the preference for using a tuner to feed a balanced or 
open wire line.??? For the life of me, I have never been able to 
understand the general belief that a 4:1 balun should be used with open 
wire feed line.?? Maybe it is the "400 ohms" or "450 ohms" that is 
attracted to the number "4" in the balun ratio that is the attraction.?? 
I view it the case of the? "tuner lemmings" where one started it 
{incorrectly as it may be} and the rest followed.

By now most of us are well aware of the need for a 4:1 Guanella balun to 
be wound onto two separate cores, not just a single core.? 
Unfortunately, most balun manufacturers are clueless and continue to 
promote these single core baluns for OCFD antennas.?? A few (e.g., Balun 
Designs and Palomar Engineers) have either dual-core?s or even hybrid 
baluns.

The secondary reason that the single core 4:1 Guanella is not 
appropriate.??? If you wrap both winding's onto a single core, each 
winding has half as many turns as when you wrap them onto separate 
cores.? Since inductance (and CMI) increases with the square of the 
number of turns, it is obvious that a single core balun could never work 
anywhere nearly as well as a dual-core balun.

But the primary reason is, in HF antenna applications, a 4:1 Guanella 
Balun wound onto a single core has no CMI at all; ZERO.? In fact it can 
even generate CMC.? (Source: G3TXQ).? Therefore, by definition, it is 
not even a balun at all. ? Yes I have read Sevick too and he shows a 
single core 4:1 Guanella balun as well as a dual core, but he fails to 
explain the difference. ?The single core will only work in applications 
that are 100% ground independent, or ?floating.???? No HF antenna 
located here on mother earth is ground independent; thus the single-core 
4:1 Guanella is not suited for HF antenna applications.

As to tuner ranges, add a length of coax or insert a piece of equipment 
in the path and the Z? +j ? is now different. Hence the appearance match 
range will be different.

In general, I agree with Bob.  For most situations, a 1:1 balun will 
produce a good match - but it all depends.

The impedance you are matching is NOT the characteristic impedance of 
the parallel feedline, but the impedance seen at the end of the parallel 
feedline.  That can vary from very low to very high depending on the 
length of the radiator, the length of the feedline, and the frequency.

The feedline transforms the impedance of the radiator depending on the 
feedline length and frequency.  Study a bit of transmission line 
principles to discover why that is true.

If you want to convince yourself, just connect an antenna analyzer to 
the station end of the parallel feedline.  If you find an extremely low 
or extremely high impedance on any band you wish to operate, try adding 
or subtracting 1/8 wavelength of feedline for that problem band and 
measure again.

73,
Don W3FPR

I called them and we did some troubleshooting of the issue.

I'm sending it back to them today. It's most likely a bad screen that will
be replaced under warranty.

The HP GPS Splitters are amplified (unity gain), AND the documents say 
that all of the non-powered (typically all but port 1) ports are 
terminated with 200 Ohm resistors to simulate an antenna load (This is 
part of DC blocking the ports and/or "tricks" the amp into working when 
all ports aren't populated. I'm going to assume that on these active 
splitters, no termination is required, just port covers to keep them clean.

There are reports online that 1:1 has lower losses. My experience is that
with lower-range tuners 1:1 does not cover some frequencies but 4:1 does.

Just depends on the Z required to match. 

Fact for T and L networks (a.k.a tuners) as the Z value decreases the loss increases.  Acting as a 4 to 1 transformer it divides the Z by 4.

It depends on whether it is an amp driving a passive splitter (YES, do 
terminate) or multiple amps, one for each output (No).

I wouldn't say they were self-terminating, but more that they don't care.? If
you have a multi-port passive splitter then I would terminate unused ports to
ensure proper splitting.? Maybe your GPS distribution amp too as it may be an
amp driving a passive splitter inside.

I've had several to ask in general,? "so what or when is the correct 
application for a? 4:1 balun?" ? The folded dipole is an excellent 
application and case for a 4:1 balun.? The uniform folded dipole feed 
impedance at resonance is ~300 ohms.? When erected less than 1/2 
wavelength above earth the impedance drops to near 200 ohms, depending 
on height. ? Thus the 4:1 transformer action in the balun bring the load 
to near 50 ohms.??? Even it the feed Z of the folded dipole is 300 ohms, 
and height above ground supports this, the SWR seen at the radio is only 
1.6:1.

These thing we call baluns should have two functions to perform: (a) 
unbalanced to balanced conversion, and (b) some degree of Common Mode 
Rejection.??? Both are equally important, although most commercial 
designs fail to address item (b).

Again I agree with Don's comment earlier, the concept of using a 4:1 
balun to "match the feedline Z" is purely fictitious information.? The 
feed line, depending on length vs. frequency being some numerical factor 
of a wavelength, has some transformer action.? Thus the feed Z of the 
antenna and the feed line in combination, will present some value of Z 
expressed as R +j.?? It has little to do with the actual feed line 
characteristic impedance.

If one believes the 4:1 balun matches the feed line which happens to be 
600 ohms, and the feed line is correctly terminated into its 600 ohm 
characteristic impedance, the feed Z at the balun is 150 ohms, 
presenting a 3:1 SWR.

There is an excellent presentation on impedance matching coming up at 
the Huntsville Hamfest in August.

None at all. Add what you want at any time after the initial build. 
You'll have a better idea what you actually want after playing with the 
base K2 for awhile.

There is no real disadvantage, other than the fact that the base K2 must 
work into a 50 ohm load for proper power control and proper PA loading.

For that reason, I would suggest the KAT2 be the first of those options 
that you add.

Thanks all for the advice. I'm going to build the base K2 first. I'll just have to use resonant antennas or the kxpa100 w/internal tuner until the KAT2 has been added.

"Generic USB Hub" when I plug in the USB cable.

 

What could I be missing or check?

Tnx for any feedback

While trying to run my KPA500 at full-tilt--but as cool as possible--in digital modes, I have noticed over the years that:
1). The KPA500 actually runs cooler at just-below-fault power output than it does at either 500 or even 400 watts output.
2)? The KPA500 runs substanitally cooler at a 1:1 SWR than it does at even 1.2:1.
Does the KPA1500 also do this?? I'd appreciate actual experience more? than conjecture.
Thanks and 73,

Eric, et & al:

I have a KPA500 on the desk.? It is about 1 month old.?? As to 
efficiency which is related to power output vs. power input, a simple 
ohms law calculation is all that's needed to see what is occurring. ? 
During transmit, note the value of HV and the value of CURRENT.? Also 
note the power output in watts. ? All of these values are on the LCD 
display.? ?? Per Ohms law, Volts x Current = watts which is DC watts 
input. ? Then Power output ? DC watts input X 100 = % efficiency.

With my amp in CW mode key down on 80M:?? Voltage = 63.0, Current = 12.1 
amps, RF power output is 575 watts.?? Thus 63.0 x 12.1 = 762.3 watts DC 
power input.??? Then 575/763.3 = .7533 x 100 = 75.33%.? ? ? In this 
configuration 762.3 - 575 = 187.3 watts of required heat dissipation.

Now at a lower power output on 80M:? Voltage is 64.6, Current is 8.8 
amps, RF power output is 300 watts.?? Thus 64.6 x 8.8 = 568.5 watts DC 
power input.?? Then 300/568.5 = .5277 x 100 = 52.77% In this 
configuration 268.5 watts of required heat dissipation.

My power measurements are made using my Bird 43 and a 50.5 ohm dummy 
load.?? I have not done a calibration on the KPA500 power meter, 
although I find it relatively accurate.

Now in each case, the difference between RF power output and DC power 
input is the watts of heat that will be dissipated.? Yes, it is clear 
that running the amp at higher power, but never to exceed the rating nor 
temperature limits is the more efficient method. By the way, those hams 
that run their tube amps at reduced power "to save the tubes" are in 
fact doing just the opposite in as much as the efficiency at lower power 
is less than at higher power. The heat has to go somewhere and it ends 
up in the amp or being exhausted by the cooling system.

As to running the amp at 500 watts, or 600 watts or 700 watts, thus just 
before fault power, I would need to examine the IMD products to be 
confident the amp is "clean".? A solid state amp which is being over 
driven just a wee bit can get really nasty on the air and real fast.? 
The product is splatter on either side of the operating frequency.?? 
Avoid this and sacrifice a few watts of output power.

As to the KPA1500, I have no experience or knowledge.? But I would say 
it follows the same rational of operating and efficiency.

I haven't measured IMD on my KPA500 either since I don't own two generators that 
are clean enough with the necessary power to do so.

I would suspect, however, that the amp is cleaner that a K3(S) driving it.

I evaluate IMD by looking at keying sidebands of a long series of dits, 
as I posted hear yesterday. Details of the measurement setup and? 
method, and lots of results, are here. 
http://k9yc.com/P3_Spectrum_Measurements.pdf

It's well known that IMD in the K3/K3S increases at rated output, and is 
a lot lower at the levels needed to drive a power amp. It takes 25-30W 
to drive the KPA500 to full power, and about twice that to drive my Ten 
Tec Titans. The K3/K3S is pretty clean at these levels. The plots for 
the two amps look almost exactly the same, and have the same shape as 
the K3 at those drive levels.In other words, neither amp is increasing 
bandwidth. Note that these measurements are of the envelope of peaks, so 
they are, in essence, capturing clicks.

IMD also increases with low DC supply voltage. I've not done any 
disciplined measurements to put numbers to it, but K6XX has. His data is 
in this pdf slide show. http://k9yc.com/K6XXAmpTalk.pdf

I received a call from Elecraft today confirming my address and the amp would be shipped out today. Tracking info says that UPS picked it up and it is supposed to be here in Florida on June 1st. This was ordered on October 16th, 2017.

I?m just guessing but I suspect this pleasant surprise is a combination of ramped-up production plus somewhat of an order lull after the orders of the first week were placed in August.

Tony,

The computer must also enumerate a COM port that is associated with the 
adapter in the K3(S).

If it goes not, go to the FTDI website and download the drivers.

It's a pain in the ass to have to unpack and repack my carry on every time I went through security but they were more concerned with liquids than any of my electronics.

I took my Kx2 on 6 flights this year. Two international. Only twice did a tsa official even open the waterproof box it was in.  And that was a newbie who just stared at it for a while until her supervisor took a quick look at it and said ?okay? it was fine to carry on.  The airlines publish on their websites the specs on the size of lithium batteries that can be carried on. The specs are given in Watts. The 2600 ma elecraft  batteries are well below that.

I travel to Edinburgh, Scotland frequently and usually take my KX3 or KX2 with batteries, both AA and rechargeable. No one there or in connection points (Amsterdam, Paris or London) has ever said a peep.

Take an an ad or manual with you so you can show them what it is.  I 
went through Reagan National, JFK and ElAl, the tightest security in the 
world, and no one said anything.  The rig, coax and antenna wire looked 
like a bomb to me.  It was in carrying-on for the trip over and packed

Somewhat along those lines, at work our Keysight tech rep (formerly 
Agilent, formerly HP) was driving to a customer location and had a 
backseat full of electronic lab measurement equipment.  He said the LO 
in something set off a police radar-detector detector, and radar 
detectors are illegal in the state he was in.  After being pulled over 
he was certain the cop would see a back seat full of cables, high tech 
gadgets, and think he was up to no good.  He told the cop he didn't have 
a radar detector and they could go through the equipment to find the one 
that set off his detector.  The cop looked at all the gear and just said 
to keep driving.  :-)

I have traveled to Europe/Caribbean a few times with my KX3.  I just packed it in my (carry-on) suitcase or in my backpack and never had a problem. I didn't pack it with batteries, because I could always just plug in a universal adapter.  You might choose not to bring batteries if you can get a good AC power adapter--just bring the appropriate plug adapters.

Also, I learned the hard way, the antenna is more important than the  radio!  I used an end-fedz which worked great only after I strung it out away from the hotel building--all the steel in the building just ruined the signal.  Get it high and as far away from other structures as possible.  Let the internal antenna tuner do it's magic.  I had a blast--and worked friends in the USA with the KX3.  Good luck and have fun!

"The KPA500 actually runs cooler at just-below-fault power output than it does at either 500 or even 400 watts output."


I ran a quick test to see if I saw the similar results with my KPA500. The quality of the data is limited by the low resolution of power returned by the ^WS command but it shows that PA heating is 350 +/- 25 W for all output power levels between 150 W and 500 W. Below 150 W the PA heating falls off with power output. The cluster of points close to 500 W lies at about 330 W heating which does support the idea that PA heating will be less at max power output. I did not extend the test beyond 500 W output.


I may try the test again with a better controlled drive ramp rate but the quality will still be limited by the resolution of power returned by ^WS. To get better results I'll need to expand my logger capabilities to include sampling of my LP-100A power data.

I don?t think the battery would be a problem with carry on.  I?ve traveled with all sorts of iPhone backup batteries, with a larger capacity and physically bigger than the KX2 or KX3 batteries, and never had a problem.

There are airline regulations regarding batteries so you should check to
make sure that your battery sizes are acceptable.  Bringing a transceiver
though security is usually a piece of cake. I have TSA Precheck which I
think makes things easier in US airports but I rarely have had to take my
K3S out of my carry-on luggage anywhere.

That's to be expected of any class AB power amplifier.? The dissipation 
may actually be lowest when it is driven into saturation, not 
recommended for any mode except CW.? And even on CW, it could generate 
key clicks.

Well .. I checked the D19 setting, and it was set to 'Y',? did the 40/80 
alignment went OK, then to verify, did the complete VCO voltage checks 
as listed in the K2 manual on p64.?? All were fine.

So far so good.? Continued on with the 40/60 alignment tuning as listed 
in the K60XV instructions, and could not get the power showing under 
TUNE higher than 0.1.

OK .. figured lets bypass the K60XV, so I unplugged the board, found the 
4.7 pF capacitor and inserted in pins 1 & 3 of J15, added a jumper 
between pins 3 & 5 on J13.?? Left D19 as set per the K60XV 
troubleshooting instructions on page 60.?? Then tried to check the 40 
meter power.

Same results.?? So I put everything back together.? Removed the 
capacitor & jumpter, reinstalled the K60XV,? put the KPA100 back on, and 
went back to the shack.

Figured I had better hook everything up (K2 & KAT100) and make sure the 
other bands can tune.?? Powered it up, and it was sitting on 40m.? Said 
what the heck, and pushed TUNE .. 2.0 watts showed up on the LCD display 
... THUD.

Could it have been as simple as not properly aligning the pins of P1 and 
J13 ?????? Even P2 and J15???? The board was recognized when I initially 
installed it,? so I'm at a loss, but happy to see 40 & 60 working.

Thanks for all the advice.

Hello,

Does your K2 need repair? Tuneup?
Want to sell it, but it needs some attention before offering it for sale? 

In addition to tuning your rig, I can also rescue a building project you might have started some time ago.

See what my clients have said about my construction and service work at

Watch Control Panel --> Device Mangler --> Ports while you plug in the 
USB cable to the PC.? You should see a new COM port come up.? That's the 
port you use to talk to the radio.? It's faintly possible you are 
missing or have an old driver, but Windows almost always installs the 
correct driver transparently when you plug in the cable.? Unplugging the 
cable will cause that port to disappear.

Hi Fred,
That is exactly what happens when I plug in or remove the USB cable. Narrowed down the problem to the KIO3B Main Board. Ordered a replacement board.

Watch Control Panel --> Device Mangler --> Ports while you plug in the USB cable to the PC.  You should see a new COM port come up.  That's the port you use to talk to the radio.  It's faintly possible you are missing or have an old driver, but Windows almost always installs the correct driver transparently when you plug in the cable.  Unplugging the cable will cause that port to disappear.

I have no idea what you are actually measuring but it certainly isn't IMD in the 
classical sense. While it might be "well known" that IMD decreases at lower 
power, it isn't necessarily true.? What is really not well known is that in the 
K3(S) IMD is highly frequency sensitive.? The 3rd order IMD in my K3S at 10W 
output varies 18 dB with respect to frequency.

Furthermore, my K3S on 10, 17, 20, 30 and 40-meters has higher IMD at 20W than 
at 100W.

The disadvantage is that you will need to unsolder some components.  In 
most cases, I think you can destroy the through holes, but there is at 
least one case where you have to insert a new value in the old hole.

There used to be a, third party, product, called UnPCBs, which provide a 
minimal dummy version of most of the modules, but the sales of the K2 
dropped to a level where it wasn't worth another production run for the 
PCBs for this.

I think I made it plain that I was measuring the "envelope" of keying 
sidebands, usually described as "clicks." This envelope is due to a 
combination of the shape of the keying waveform and IMD.

FWIW, I really don't care about IMD as a number. What I'm concerned with 
is clicks, splatter, and phase noise from another station that's loud 
covering a weaker station I want to work.

Right -- it depends on the transmitter design and implementation. K6XX's 
work shows that to be true of the K3, and my measurements (done on 20M 
as I recall) confirmed it.? I also recall that you noted increased IMD 
around 15W, which is likely the result of the K3 firmware causing the 
power amp to be turned off and the QRP output stage to be driving the 
load at it's full rated power. Under that condition it is consistent 
with my (and K6XX's) observations that IMD is often lower at reduced 
power output.

That's news to me.

Again, the power amp is not engaged and you're running on the driver. 
But that much variation also implies a problem. Have you sent the rig 
back to Elecraft?

Hi John,

Reliability of the PX3 front panel circuit board and LCD is extremely high (ditto with the P3). We do get an occasional request for LCD replacement, usually after the PX3 has been operated portable and sustained damage in transport. 

The bezel (~$21 replacement cost) usually takes the brunt of the damage. If a new LCD is required, it's ~$100. Replacement instructions can be found in the PX3 Owners Manual. 

I don?t think we?ve ever had to replace an entire PX3 front panel module. We could repair it in virtually any scenario short of grizzly attack.

That's to be expected of any class AB power amplifier.? The dissipation may actually be lowest when it is driven into saturation, not recommended for any mode except CW.? And even on CW, it could generate key clicks.

In casual conversation, I had an Elecraft developer suggest that 
to minimize IMD, you don't want to drive an amplifier with the 
K3 output power near the top of the QRP amp range (just below 12 
or 13 watts). I generally stay below 10 watts, but would like to 
have the 100W amplifier automatically engaged if that will 
reduce IMD.

Note: I am sometimes driving my Expert 1.3K amp to 100 watts 
output on FT8 just to save the batteries powering my K3. It also 
makes it easy to QRO, and I have a couple of FT8 contacts in my 
log -- with a DU and a JA -- reporting me at -24 dB where I was 
operating at 800 watts. YMMV.

Why do you think you need 800 watts in a weak signal mode? Do you have any idea what that does to other operators? I?ve made several 10,000+ mile contacts with 50 watts, as have others who are following the ?rules.?

I?ve seen Bill?s setup. 50 watts with a decent gain antenna (i.e. beam) is equivalent to 800 watts with Bill?s antenna and QTH. He really has done an outstanding job with the resources he has to work with.
Also remember, we are talking about a 4 to 5 db difference in power here. And when you have pretty large mountains blocking your path to JA and EU, that 4db of power can make a huge difference.
QTH and the antenna system really make a huge difference!

I see no disadvantage.  

I have built three, each of which has all of options you are considering.  As David says there are some parts that need to be unsoldered, and a couple where the through-holes need to be cleaned up for inserting something else.  Nonetheless, when I built mine even though I ordered the options at the same time as the base kit, I finished the base kit completely first, then went back in to add the options.  Two reasons -- first, if there were to be a problem somewhere I wanted to be able to analyze it in the least complicated way.  So, K2 first, test, then each option and its test.  Second -- it's a kit.  That's part of the fun.

This didn't seem logical or possible to me.  So I tried it and discovered
the problem occurred on 6m, but not on 80m with my K3 and firmware 5.64.
Interesting.  This K3 (S/N 08343) has a recent EE INIT and re-load of
firmware and configuration after experiencing a power overshoot issue (now
solved).

Many of us combine our affinity for radio with other activities we?re equally passionate about ? perhaps more. An obvious example (one that renders this post marginally non-OT) is hiking / camping; for some of us, it?s a natural environment for small radios and big ambitions. 

What are your ham-activated avocations? Do they come with as-yet-unsolved problems in the field of radio ergonomics? 

Where is the boundary between communications media and the things you most enjoy talking about?

Since the numbers are more-or-less specified by Elecraft I'll go by them.? I say

You recall incorrectly.? First, I've never stated that and second, the HPA 
engages at 12 W.? I have however, stated in strong terms several times in this 
and other forums that a K3 should never be operated above 10W on the LPA.? I and 
others have asked for a firmware change that would insure this.

Yep.? Which is why I state that I can't with reasonable confidence measure 
KPA500 IMD.

Where do I look to see how to troubleshoot a K3s at the shack and just
order the new parts.

I'm looking to buy a radio that does not need to be sent back to the
manufacturer for basic repairs. I'd also like to buy a radio from a USA or
North American company for support.

Gerald,

Repair implies a failure has occurred.  Most radios these days, and  
certainly Elecraft, are highly reliable rigs short of receiving some sort  
of abuse.  Sure, failures do sometime occur, but fairly rare.  There are  
countless thousands of Elecraft and other radios on the air after years of  
use with no problems.  Many being carried to mountain tops (SOTA) and back  
frequently.  I bought a TenTec Triton IV in 1978 (?) when they first came  
out - the first solid state full CW QSK rig ... and quite a few rigs  
since.  Haven't had one failure on any of them in those 40 years.  I don't  
think you have much to worry about.

72, Paul NA5N

I have recently discovered the thrill of "aeronautical mobile" on 2m FM
using a handheld.  Line of sight has an entirely different meaning at 8000
feet in unobstructed air!

I would dearly love to figure out how to operate HF (20 meters) while
flying a small general aviation single-engine aircraft.   Haven't figure
out a workable antenna solution that doesn't require airframe modification,
etc.  I thought about a Zepp like the old days, but at 180+ mph that is
probably not workable.

I can think of a couple of things where my ham radio experience blends with
my other interests.  Radio Control Models: for many years I used the 53 MHz
band for my RC link.  Now that the GHz equipment has come along, I use
that.

 Music: I play trumpet in a couple of bands. My experience with Morse Code
has helped me (my opinion) be more precise with timing or rhythms.  I also
believe, although I'm not sure studies have proven, that ability to learn
and use Morse Code is highly correlated with musical ability.

Flying: I hold Commercial, Multiiengine and Intrument ratings.  When I was
taking lessons, flying cross country using VORs (before GPS), I would tune
to the next VOR, I.D.it by hearing the Morse identifier, and turn the
volume down.  My instructor would then lecture me on the need for properly
I.D.ing the station before turning down the volume.  I had a hard time
making him understand that those dits and dahs were telling me the same
thing the voice would have.

In the Navy, I was assigned to the deck force because I was waiting for an
opening to attend ET school.  The Navy's policy at that time was that I
didn't know anything until I had been to their school.  I copy CW at 25
wpm. While on watch, I read the light of the ship that was steaming with us
and realized that they had signaled for a U-turn in front of us.  When the
message failed to come down from the signal bridge, I informed the Officer
of the Deck.  Sure enough, they turned and we avoided colliding with them.
A few minutes later, he came over to me with a puzzled look and asked how I
knew they would be turning.  I told him I read the light.

I learned Morse in the Boy Scouts, on my way to becoming an Eagle Scout.  I
teach Radio Merit Badge to Scouts now.  Although Morse requirements have
been eliminated from the requirements, I still hope that some young person
will catch the magic and join our ranks.

73,

Dave, K4TO

This list has some very knowledgeable people that are most helpful when

have quickly shipped me warranty parts for my K3S and making the repair was
easier than sending the radio back. Their customer service is second to
none.

My wife is a bird photographer (hobby, not professional, although she has been published).  But, going with her on these trips is not like a hike or walk in the park.  She will stalk a given bird for an hour or so waiting for the perfect shot.  Me, I would be standing there waiting.

So, more often these past couple of years I will park someplace convenient with my KX2 and Buddipole.  A few times I have even carried along a folding "card" table and chair if some other type of sitting area is not available.  This has actually become my favorite type of operating.

Phil,

Yes, I'm catching up on e-mail.

Your description of physics cirriculum brought me back to my high school
physics which was called "PSSC" based on the work done at MIT and described
in:  https://en.wikipedia.org/wiki/Physical_Science_Study_Committee.  I had
been licensed a couple of years by then (1962) and found PSSC physics fit me
to a tee!

My bachelor studies in vocational education decades later showed how the
approached used by the PSSC was smart and useful, something being
"re-discovered" today by educators who often are behind their peers.  The
Wikipedia article above includes a mention of Heathkit's products that were
modified to fit the PSSC model.

In between high school and my vocational education experience I taught
electronics for Eastern New Mexico University while stationed at Canon AFB. 
I used the text by Robert Schraeder "Electronic Communication" which one can
find used today.  I lent mine to my Air Force boss and bought another
recently.  Schraeder, like so few, has the ability to write clearly about
difficult concepts that makes them seem simple.  That text made my teaching
much easier!  "The Art of Electronics" will certainly fit into my reading
schedule, in which I am also way behind.

73, Bill, K8TE

"My undergraduate degree is Physics and back in the 1960s, my physics
curriculum included a similar course study.  This was all about using lab
equipment but also making the necessary little electronic gadgets that were
important to work in a physics research laboratory.  When I took my course,
the book "The Art of Electronics" did not exist and we never had a text book
in our course."

Writing...

Always wanted to be a writer. Started writing what today would be called 
a "journal" back around 1960 when I was 9 years old, writing about 
astronomical events and the space race. Got a Remco crystal radio kit 
about that time, got hooked on radio, so I started writing about radio.

My first article was published in 73 magazine. Some 1,200 articles and a 
half dozen books later, I am still writing about radio 50 years in!

I recently bought and installed the KX3-2M transverter module in one of my KX3s and am enjoying a much better experience receiving the downlink from the Mode B AMSAT birds, compared to the TH-F6A I was using previously. Sensitivity and ergonomics are a huge improvement.??
Unfortunately, I find that the SMA connector loosens very quickly. I've already had to open the case and almost completely uninstall the transverter once (undoing and redoing everything except the internal coax connections) just to retighten the nut, and it's already worked itself loose again. Does anyone have a trick they used to keep the nut from loosening? I can't get a lot of leverage with needlenose pliers with such a skinny nut in such close proximity to fragile components, and the thin lockwasher doesn't seem to be very effective. I thought I had cranked it down pretty tight, but apparently not tight enough.?
I seems that it would have been better to have the separate nut on the outside end of the connector (like the connectors on the PX3), since those can be tightened up very easily from the outside.?
One option might be to use Blue Loctite. I don't think I'd ever need to remove it unless Elecraft comes up with a dual-band (2M and 70CM) internal transverter to replace it, but this option would likely be? permanent since I don't think I could get enough mechanical leverage to break the Loctite and don't think heating up the connector to loosen the Loctite would be a good idea.?
Any better ideas?
Thanks and 73, Ryan AI6DO

Gerald ..

If you?re looking for the 50 page "troubleshooting and diagnosis" guide for the K3, it isn?t something you?ll find.  But as others have said, this list and Elecraft support are invaluable resources.

The K3 is largely built to be module replaceable.  But the modules themselves are also repairable, as long as you?re willing to deal with SMD components. One of the several benefits of building one (as opposed to ordering a factory built version) is that it eliminates the fear of taking off the covers.  Another is that you get familiar with what?s in the box, where it is, and will have at least installed it once.  You just use the construction manual backwards to get it out again.  But even a factory built radio does NOT come with one of those stickers that causes your warranty to be terminated if you ?break the seal?.

I built my K3 back in 2007 or so.  I?ve been into it over and over again installing new or updated versions of boards,  or applying updates to individual boards.  I?ve never actually had a board/component failure (knocking very hard on wood), and think that?s the likely case for most of us. And it?s never been back to Elecraft to cut a trace, install a jumper or a new part, etc.  YMMV :-)

Thanks Paul:
You have some wonderful luck. I bought a Tentec Eagle and Omni 7 and both failed within 2 years. I opened both to look for problems. though both were labeled ?Made in USA? most components were labeled ?Made in China? and are no longer available. For both repairs they need to be shipped back to Tennessee to their shop now employing a part time repair person. Reading the forums, reliable repairs are questionable. So I?m about ready to give up on the hobby.

> Repair implies a failure has occurred.  Most radios these days, and certainly Elecraft, are highly reliable rigs short of receiving some sort of abuse.  Sure, failures do sometime occur, but fairly rare.  There are countless thousands of Elecraft and other radios on the air after years of use with no problems.  Many being carried to mountain tops (SOTA) and back frequently.  I bought a TenTec Triton IV in 1978 (?) when they first came out - the first solid state full CW QSK rig ... and quite a few rigs since.  Haven't had one failure on any of them in those 40 years.  I don't think you have much to worry about.

It's been a long time since I did this, but I remember there are a couple
of connectors for the option boards that can be installed during the main
board assembly, and make a tremendous difference in ease of installing the
options when you get around to it.  So there's an advantage in buying at
least some of the options right away -- I think the sideband board, and
maybe the tuner?

If I remember right, the noise blanker has some unavoidable disassembly
when it's installed, but not so much the others.

Schraeder was the text for my Communications class in tech school in the
early 80s.
One requirement to pass the course was to earn the FCC General Class
Radiotelephone license. I believe nearly everyone in the class did. It also
made it pretty easy to upgrade my ham ticket from Novice to Advanced during
that time.
I still have my copy and still refer to it from time to time. The
fundamentals never change.

I've done a couple of repairs on my old K3: blown pin diodes on the 
transverter board, and the corroded 12 vdc connector pins on the KPA3 
amp. Have also done several component-level mod kits supplied by Elecraft.

I think Elecraft will supply all K3 parts that are still in production 
and, if I'm not mistaken, they stockpile end-of-life components for 
future repairs. But you can't expect parts to be available forever.

FWIW, I recently managed to find a ceramic filter for my Argonaut V that 
is out of production. I ordered directly from TenTec. Amazingly they 
still had a few in stock.

For both repairs they need to be shipped back to Tennessee to their shop now employing a part time repair person. Reading the forums, reliable repairs are questionable.

Sure, failures do sometime occur, but fairly rare.  There are countless thousands of Elecraft and other radios on the air after years of use with no problems.  Many being carried to mountain tops (SOTA) and back frequently.  I bought a TenTec Triton IV in 1978 (?) when they first came out - the first solid state full CW QSK rig ... and quite a few rigs since.  Haven't had one failure on any of them in those 40 years.  I don't think you have much to worry about.

I can really relate to these two.

As a kid I played drums. My father taught and played pretty much all his 
life until his hearing gave out. Though my CW has never been more than 
remedial mostly the sense of rhythm and timing is mostly excellent and I 
attribute it to those early years. When I took the then GPO 12wpm UK 
Morse test the coastguard guy did comment on my good fist.

On the navaids ID I have a good one. Just recently I commissioned 2 
ILS's out in the Middle East, though primarily for the US Air Forces 
use. I had a good raport with the tower guys and would often spend time 
up in the tower. Having just programmed the ILS idents I asked a 
controller to have one of the approaching aircraft take a listen and 
report the code back to be sure it was keying okay. It seems this, to 
me, simple request caught this particular KC135 crew off guard. "Wait 
one", came back the response, a couple of minutes later, somewhat 
confused sounding they came back with a "er, well, its kinda dee dee 
doh, doh dee doh, dee dee". Took me a second or two to figure they had 
actually got it right just with no spacing. I guess they don't teach 
pilots code now either.

Though I've never worked on navaids in the US, only in Asia and EU, I've 
never done one with a voice ident, only ever CW.

Ryan,
I experienced the same issue on my kx3 also. I was able to tighten it down
enough with a wrench to keep it snug so far, but still keep an eye on it. I
also thought abt locktite but didn't like the idea of introducing non
conductive material between the case and the jack.

I recently bought and installed the KX3-2M transverter module in one of my
KX3s and am enjoying a much better experience receiving the downlink from
the Mode B AMSAT birds, compared to the TH-F6A I was using previously.
Sensitivity and ergonomics are a huge improvement.
Unfortunately, I find that the SMA connector loosens very quickly. I've
already had to open the case and almost completely uninstall the
transverter once (undoing and redoing everything except the internal coax
connections) just to retighten the nut, and it's already worked itself
loose again. Does anyone have a trick they used to keep the nut from
loosening? I can't get a lot of leverage with needlenose pliers with such a
skinny nut in such close proximity to fragile components, and the thin
lockwasher doesn't seem to be very effective. I thought I had cranked it
down pretty tight, but apparently not tight enough.
I seems that it would have been better to have the separate nut on the
outside end of the connector (like the connectors on the PX3), since those
can be tightened up very easily from the outside.
One option might be to use Blue Loctite. I don't think I'd ever need to
remove it unless Elecraft comes up with a dual-band (2M and 70CM) internal
transverter to replace it, but this option would likely be  permanent since
I don't think I could get enough mechanical leverage to break the Loctite
and don't think heating up the connector to loosen the Loctite would be a
good idea.
Any better ideas?
Thanks and 73, Ryan AI6DO

Let me correct myself before others do. Its a 12db difference. And I will rib Bill about it. Still, to the west and north he has very high hills/mountains that block the RF path. Makes me wonder if he was using reverse path for the QSOs.

Wayne,
     Here on the east coast, we have boaters who run up or down the intracoastal waterway. The direction is dependant on season. Ham radio is used for two important purposes, the marine nets and non-business email. In the morning, the Waterway Net meets for traffic, position reports, and items of interest. The Maritime Mobile Net meets during the afternoon, east coast time, for assistance to voyaging boaters.

     Email is passed and received through the Winlink network. With stations world wide, a boater can have access on some band almost anytime. And, all of this, doesn't even touch on the other ham activities. Bjorn points out that he uses his backstage, so do the majority of sailors. Having gear that tolerates a salty environment would be great..

73,
Barry

Speaking of music: I earned a music minor in college, and CW helped quite a bit. The rhythm final was to sing or clap a chaotic collection of eight notes and dotted quarter notes -- basically dots and dashes -- so I did Morse a cappella and got an A :)

If you are looking for a radio which won't fail, I suggest one keep your money in the bank.  All new radios, all brands, have a known failure rate, out if the box, at one year, and two years.  That is the reason companies offer a warranty. They expect some number but of units to fail during the warranty period.  Nothing unusual about this fact. 

As to personally repairing one of the modern radios, unless one has capability to handle remove and replace surface mount components, as well as rather extensive test equipment and advanced knowledge of electronics, one is relying on board or modular exchange.  This does involve the factory an leaves one with a nonworking product for a period of time. 

For a period of years I repaired many ham radio products for others. In probably a majority of cases I had to not only find and repair the original fault, but.....I had to correct the attempted repairs of others. 

Like many other products, we are moving more and more to a toss and replace commodity.

Well stated.  It's ridiculous to believe that with all of the components in
a transceiver, one will not fail or that a design could not improvement once
hundreds+ of the product are being used daily by various customers.

If you are looking for a radio which won't fail, I suggest one keep your
money in the bank.  All new radios, all brands, have a known failure rate,
out if the box, at one year, and two years.  That is the reason companies
offer a warranty. They expect some number but of units to fail during the
warranty period.  Nothing unusual about this fact. 

As to personally repairing one of the modern radios, unless one has
capability to handle remove and replace surface mount components, as well as
rather extensive test equipment and advanced knowledge of electronics, one
is relying on board or modular exchange.  This does involve the factory an
leaves one with a nonworking product for a period of time. 

For a period of years I repaired many ham radio products for others. In
probably a majority of cases I had to not only find and repair the original
fault, but.....I had to correct the attempted repairs of others. 

Like many other products, we are moving more and more to a toss and replace
commodity.

I agree it is a weak signal mode. Years ago I used to set up the KX3 at 5 watts and VPN back to my home network from the hotel and operated JT65 and JT9 remotely quite successfully.  Unfortunately the advent of FT-8 has introduced a large number of individuals not brought up in the tradition of using low power to communicate on a weak signal mode.  The reality is the introduction of those who run high power has changed the weak signal FT-8 ecosphere, and for the worse.  Sadly high power has become the new normal.

On the bright side last night I worked ZL4TT from EN63 (8395 miles) and OK2ZU (4524 miles) using an abusive 15 watts from the KX3 and a Butternut HF-9V vertical.

Ryan,
Another option is to use a short length of coax, sma male to sma female, to
avoid the issue of something torquing the SMA jack on the KX3 loose.
Something like this?

Subject: [Elecraft] PA DISS fault and relationship to SWR
Message-ID: <MW2PR16MB236276BF82A92369EF0139778C680@MW2PR16MB2362.namprd16.prod.outlook.com>

Up until this weekend I had experienced 3 PA DISS faults with my new KPA500.   I provided data to Elecraft and, after a fairly long and informative email exchange, I was told the fault is very rare and most likely caused by some problem at my station.

I developed a 10 frames per second data logger which polls and records data from the KPA500 serial interface as well as the ALARM signal available on the AUX port.  The ALARM signal was also used as a trigger so that 'scope data could be time correlated with the logger data.   CQ WPX CW contest seemed to be a good opportunity to gather data if the fault could be reproduced.   After experiencing 5 PA DISS faults on 20 meters I abandoned the contest, looked at the recorded data, and ran some additional tests.

The data show that PA dissipation (DC input power - RF output power) is strongly dependent of load SWR.  That in itself is probably not surprising.   What was surprising was that my KPA500,  when operating into an antenna load that the KPA500 reports as 1.4:1 SWR, has a PA DISS of 500 W when producing 400 W output.  What was more surprising is that, although the PA DISS fault is designed to trip at 400 W ("The PA Diss uses non-averaged data to do a comparison between the calculated power from PA voltage and PA current and the measured output power. If it is more than about 400 watts on four consecutive checks (each 8 mSec apart) then we declare the fault.") it did not trip for a key down test lasting several seconds.

Sample data for different load condx shown below.  None of these key down tests resulted in PA DISS fault.

SteppIR: LP-100A SWR 1.58:1                                                                                           PA DC Input / RF Out / PA DISS

Can someone at Elecraft please explain why PA DISS fault does not trip when key down PA DISS (calculated from WS and VI serial data) exceeds the 400 W threshold defined for this fault condition.  When the PA DISS fault was seen in the contest it always happened during the first element of the CW transmission.


Raw logger data, Excel data, and scope traces have been saved.  KPA500 firmware is 1.54.

I just finished my K2 build, with all the options and Agree with Peter, 
there if you buy the options now, the K2 manual will point out just when 
you should install the various plugs and other components during the 
main K2 build.

My advice, all the K2 manuals are online as PDF at the Elecraft 
website.? I took a look at them prior to ordering my K2, and saw where 
the various options are referenced.? That made my mind up fairly easily.

For instance, at the end of the Front Panel assembly of the K2, it has a 
section for 'uninstalled components'.? It lists those component areas 
that should not have anything? installed, however, it then tells you 
that these areas are for the KSB2 SSB adapter, and if you have it, you 
should go to that option kit and install these components now, according 
to the KSB2 kit instructions.??? I do advise that you do the inventory 
of the KSB2 so you know all the parts are there, get the ones you need 
to install on the Front Board, and set the rest aside.

Trust me, getting the ones you listed with the K2 will save you a lot of 
time, and desoldering later.

*WHEN* will people get it through their heads that WEAK SIGNAL is
not the same as low power?  The original "weak signal" mode is EME
yet almost 100% of EME work is done with high power - 1500 W on
CW and often 1000 W (or more) even with JT65 - plus extremely high
gain antennas (well in excess of the largest "stacked arrays" on HF).

*THERE IS NO "TRADITION" OF LOW POWER FOR WEAK SIGNAL MODES*

Conflating weak signal and low power is an artifact of PSK31/63/125
HF operation where lids run a 2 - 3 KHz wide passband or SDR rigs with
no RF/IF filters and then complain when strong, adjacent signals
overdrive their (cheap) sound cards or drive the IF/mixer/ADC of their
cheaply designed transceiver into distortion or overflow.

Use the same techniques that have been used for decades with *WEAK*
*SIGNAL* modes - narrow IF filters, strong preamplifiers, IF chains
with high compression levels, mixers with high IMD thresholds, etc.
- and there is no conflict between high transmit power and  weak
signal modes.

I agree with Mike, 
 
Because of Arrow-induced self-flagellation, I'm using a SMA to BNC cable when I do satellite work, with the adapter cable secured with a little homemade clamp at the knurled KX3 cabinet screw to keep stress and torque off the KX3 connector.

Subject: [Elecraft] Ham radio as a side dish
Message-ID: <201805261849.w4QInWx0003864@mail47c28.carrierzone.com>

For 35 years I raised and ran sled dogs here in AK.  1982-1988 I 
volunteered as radio operator from remote checkpoints on the Iditarod 
Sled Dog Race held each March from Anchorage to Nome (nearly 1200 
miles thru the AK  roadless wilderness).  In the early years of the 
race, ham radio provided communications for reporting progress of the 
teams using 80/40m and for supporting logistics (every thing either 
hauled by snowmachine or by light aircraft).  A lot of fun living in 
a wall-tent at -60F!

1989 I was hired as a marine radio operator in support of the Exxon 
Oil Spill outside of Valdez, AK.  Spent 13-months on that job.
My ham radio/2-way radio tech and experience as an emt got me that job.

I also have carried an HT while hiking/backpacking in the Sierra of 
CA (1970's).

"Drag a wire behind you like they tow banners."


If it were as simple as you suggest then I think a few of us would be doing it. Picking up banners with an aircraft in flight is a skill that most pilots don't have. It would be far better to use a retractable antenna. However, a legal installation of any sort of antenna extension/retraction mechanism on an aircraft with a standard airworthiness cert would be a significant challenge.


(No banner experience but I do have lots of time towing gliders and flying jumpers)

Gerald,

There are no details for how to troubleshoot to the component level.  In 
most cases, the FRU (Field Replacable Unit) is a board.

In some cases, Elecraft support is able to assist with your 
troubleshooting as long as it does not get too involved.  Many times 
customers have replaced components such as PIN Diodes and several such 
items.

So if you have test equipment and troubleshooting skills as well as 
equipment and skills for repairing SMD circuits, it can be done without 
sending the radio to Watsonville.

Be aware that level of skill is not the norm for the Elecraft customer 
set.  It was the norm for K2 builders several years ago, but conditions 
have changed and the average customer does not have the capability to 
repair his own radio - especially since the circuit density has 
increased many-fold and we encounter many hams with "shaky hands".

If you want a radio that you can build and thus have some knowledge 
about "what makes it work", I might suggest building an Elecraft K2 
which is still a top performing transceiver.

Don W3FPR

I?ve seen Bill?s setup. 50 watts with a decent gain antenna (i.e. beam) is equivalent to 800 watts with Bill?s antenna and QTH. He really has done an outstanding job with the resources he has to work with.
Also remember, we are talking about a 4 to 5 db difference in power here. And when you have pretty large mountains blocking your path to JA and EU, that 4db of power can make a huge difference.
QTH and the antenna system really make a huge difference!

Yes, very sad. Either they don?t realize or don?t care that their huge splattering signals make it difficult and unpleasant for those who are trying to be true to Joe Taylor?s vision.

Outstanding! Those are the moments that are made possible with skill, patience, and perseverance, not just fat checkbooks. A few nights ago, with my hex beam literally on the ground (for adjustments), I worked India on 20 meter FT8 using 50 watts. I jumped for joy when that guy came back through the ?pileup? to my call! 8720 miles! My report wasn?t stellar, but who cares?

Unless the FCC imposes power restrictions on FT8 and other weak signal modes, it will just get worse and become a battle of bludgeoning titans. I see no end to it, alas. Somehow, it reminds me of the poem ?Ozymandias.?

Ryan,

You need 2 wrenches (not pliers) - preferably thin ones.  Tighten the 
nut down until the lockwashers bite into the KX3 enclosure metal so the 
teeth have good conductivity to the enclosure.

For me music ability aided sending good CW, not the reverse.  I 
played a band instrument from 5th grade thru end of HS, but acquired 
my Novice in my 8th grade (Nov. 1958, almost 60-years ago).  I passed 
the tech. 1959 (which used the General Class written exam) a year 
before taking algebra.

I also sang bass in church choir so music probably helped 
(something).  Church Choir netted me a girl friend.

Now back to your previous program (ham radio?)

THIS!? There is no substitute for having the correct tools for the job!!

There are multi-size thin spanner wrenches made JUST for SMA and other 
small connectors...? Here is a link to the one that comes with my 
SDR-Kits DQ8SAQ VNWA:

https://www.sdr-kits.net/Flat%20Spanner

They sell it separately.? Of course, you could also buy a super 
expensive set of thin spanners...? <wink>

Additionally, as I study up on using my VNA, I have become more acutely 
aware that connectors have make/break cycle limits.?? They DO wear out, 
especially if you over-torque them.? On PCB soldered connectors, it is a 
pain to replace them, so one might consider extending the lifespan by 
placing a sacrificial SMA Plug to SMA jack adapter in between the SMA 
jack on the radio and the feed-line....? IMHO, especially on portable 
radios/devices that are setup and taken down repeatedly, it is worth the 
additional insertion loss.? Just buy Amphenol or better quality ones and 
that is minimized.? Here's a link to a good one.

https://www.sdr-kits.net/sma-male-to-female

A good adapter will give you 500+ make/break cycles and still remain in 
spec.? Then, you just buy a new adapter rather than have to desolder and 
re-solder the PCB soldered, end-firing SMA jack.... assuming you can 
find the right one.
Thus the make/break cycle on your device only increments by 1 instead of 
500+.

Additionally, there IS a torque spec for SMA connectors...? It's about 4 
Lb-in for a brass connector, a little higher for stainless steel.? When 
mating stainless steel and brass fittings together, use the lower torque 
figure.? You CAN get fixed torque wrenches for connectors; they are not 
cheap.? I use my thin spanner or a flare fitting wrench and a Lyman 
trigger pull scale IF/WHEN I want an exact torque.? Main deal... don't 
over torque a connector.? I WOULD torque the adapter to the device jack 
using some method of measurement system.? Then, connect the feedline 
with the spanner...? The jack side of the adapter will spin on the 
rubber seal before reaching 4LB-in.... built-in over-torque protection.

Here's an example of an SMA torque wrench.... a very reasonably priced 
one all things considered:

Good point about "weak signal".  Really refers to receiving and not 
transmitting.

Example: eme operators are so dense in population in EU they have 
mutually agreed to transmit during the same sequence in order to 
minimize interference.

New: digital modes use on HF *should* augment operating during poor 
propagation (when signals are received weakly).  During normal *good* 
prop one should lower power accordingly to what is sufficient.

HFer's lower their power - huh?  That's a joke, right?

I live in town, and the local noise level is normally S9 or so on the lower bands, but nothing shows on the display on any band, even though the K3 is picking-up signals.  Any ideas?

Joe should build in a random number generator that generates a random 
between 1 and 20, then apply that number to signal strengths by adding a 
+ in front of it.  If you are stronger than the random number, WSJT-X 
drops your call from the list...

Personally, I would read through the kit assembly instruction for the K3S and see if the module tests were helpful.

http://www.elecraft.com/manual/E740259%20K3s%20Assembly%20Manual.pdf

When you need more than that, I?ve seen awesome support on this list and from Elecraft support. They will often suggest a specific component to test and replace.

Hello Doug,

My guess would be that the cable that should connect the P3 "RF IN" BNC to
the K3 "IF OUT" BNC is either not fully-engaged on both ends, or is
defective.

They do banner towing at the airport I was taking lessons at. What I had 
in mind was more like dropping a wire antenna like they drop the banner 
hook without the need to fly low and actually hook a banner.? But I 
wasn't really being serious either.

Not me, a friend of mine...

Who is a pilot.  Not just a pilot, but certified by the FAA to give check
rides for small airplanes.  I don't know the specifics, but he does
aerobatics and all that.

Anyways, he's a contester and DX'er as well.

But, even though I'm sure he's a really good pilot, even he had to have a
check ride.  He was up near New York City, having a check ride and
apparently there is a flight area along the Hudson River that is really,
really tricky.  Has to be flown just about perfect, so that was his check
ride area.  His instructor, who apparently was at an even higher level,
told him to request the clearance for that corridor and ATC gave it to him
immediately.  His instructor wasn't expecting that and told him words to
the effect of "Be careful.  You talk better than you fly."

Apparently ATC tends to be hesitant to clear private pilots into that
corridor, but years of DX and Contest operations gave him the, shall we
say, savoir faire to be cleared without hesitation.  His request was
apparently crisp, clear, unequivocal and brief.

For my part, having been a cop since 1980 I've usually been the guy folks
go to for technical stuff.  Beyond radios, even.  Somehow I am expected to
know about cameras, computers, networking... and I've even picked up quite
a bit of it on the way.

If it were as simple as you suggest then I think a few of us would be doing
it. Picking up banners with an aircraft in flight is a skill that most
pilots don't have. It would be far better to use a retractable antenna.
However, a legal installation of any sort of antenna extension/retraction
mechanism on an aircraft with a standard airworthiness cert would be a
significant challenge.

All,

SMA's are also supposed to be torqued to 9 lb./in.. They make break over open end torque wrenches to do just that 
They are spendy so unless your installing hundreds of the things I'd use a deep well socket and a thin combination wrench of appropriate size.
I haven't looked at the transverter install procedure but can?t imagine trying to get the connector tight with the radio full of "stuff".

Subject: Re: [Elecraft] KX3 2M module SMA connector loosening

THIS!  There is no substitute for having the correct tools for the job!!

There are multi-size thin spanner wrenches made JUST for SMA and other small connectors...  Here is a link to the one that comes with my SDR-Kits DQ8SAQ VNWA:

https://www.sdr-kits.net/Flat%20Spanner

They sell it separately.  Of course, you could also buy a super expensive set of thin spanners...  <wink>

Additionally, as I study up on using my VNA, I have become more acutely aware that connectors have make/break cycle limits.   They DO wear out, especially if you over-torque them.  On PCB soldered connectors, it is a pain to replace them, so one might consider extending the lifespan by placing a sacrificial SMA Plug to SMA jack adapter in between the SMA jack on the radio and the feed-line....  IMHO, especially on portable radios/devices that are setup and taken down repeatedly, it is worth the additional insertion loss.  Just buy Amphenol or better quality ones and that is minimized.  Here's a link to a good one.

https://www.sdr-kits.net/sma-male-to-female

A good adapter will give you 500+ make/break cycles and still remain in spec.  Then, you just buy a new adapter rather than have to desolder and re-solder the PCB soldered, end-firing SMA jack.... assuming you can find the right one.
Thus the make/break cycle on your device only increments by 1 instead of 
500+.

Additionally, there IS a torque spec for SMA connectors...  It's about 4 Lb-in for a brass connector, a little higher for stainless steel.  When mating stainless steel and brass fittings together, use the lower torque figure.  You CAN get fixed torque wrenches for connectors; they are not cheap.  I use my thin spanner or a flare fitting wrench and a Lyman trigger pull scale IF/WHEN I want an exact torque.  Main deal... don't over torque a connector.  I WOULD torque the adapter to the device jack using some method of measurement system.  Then, connect the feedline with the spanner...  The jack side of the adapter will spin on the rubber seal before reaching 4LB-in.... built-in over-torque protection.

Here's an example of an SMA torque wrench.... a very reasonably priced one all things considered:

Subject: [Elecraft] Ham Radio as a Side Dish
Message-ID: <3B1E45E4-9B25-4D61-802A-53493C19E4DD@law.du.edu>

Like many others on the list, I survived decades as a pilot (commercial-instrument, multi- and single- / former CFI / some noncompetitive aerobatics / and a glider rating.)  In fact, I discovered long ago that many GA pilots are hams and vice - versa.  More than one might expect.  The advantage of ham radio is that I don't need a medical certificate to keep doing it (lost mine in 2011 after battling with the FAA for a series of "specials").  It is also far less expensive; unlike owning airplanes, I never had to convince the XYL that owning a transceiver was financially reasonable.

A second connection is radio astronomy, along with the related subject of SETI.  Anyone know if Paul Allen was ever a ham?

    Many of us combine our affinity for radio with other activities we?re equally passionate about ? perhaps more. An obvious example (one that renders this post marginally non-OT) is hiking / camping; for some of us, it?s a natural environment for small radios and big ambitions.

Ham-activated avocations....

Rebuilding the instrument cluster in a 1988 Ford Mustang for road racing. Two fasteners, two factory Ford plugs and presto...out comes the dash pod!

Mega squirt air/spark/fuel engine management KIT, yes lots of soldering, same car now with a race built 347 stroker and a new engine harness for the new mass air meter, O2 sensor, 32# injectors.  Connects to a laptop pc for on the go engine tuning.  Also came with an engine simulator kit to test the final assembled board.

This car competed in the Nevada Silver State Classic and on road course tracks in WA and OR.

High speed electric model boats, hydros, sponson riggers, tunnel cats, mono hulls,
Many scratch built, all needing servos, speed controllers and RC gear. These were raced competitively against others racers in the different classes at the local area racing ponds. 

These were all things my son and I did together.

Who says hams don?t have other connected interests?!  Life is full of adventures, what are some of your ham inspired activities??

And after almost 54 years of hamming, finally made it to Dayton the last two years!

Hi Wayne:

Recently I had a problem with my PX3. The VFO A cursor bar was black instead
of green and some other artifacts. Elecraft support said it was probably the
LCD and I would have to replace the front panel board and LCD at a cost of
over $500. I consequently bought a used PX3 at much less than $500. I still
have the PX3 with the "defective LCD". I would still like to get it repaired
if it's around $100 or so. :-)

73, John N1JM

Congratulations to have found the cause.
If signal level on P3 screen becomes unstable while the BNC cable is completely plugged in at both sides, check the cable itself.
My case was that the signal level was unstable and sometimes went very low. I had thought that K3 or P3 circuit was in trouble but found that connection inside one end of BNC cable connector was unstable. Replacing the cable completely fix the problem.

Subject: [Elecraft] A little late, but.... CQ WPX (CW) going on right now
Message-ID: <B30D014B-0354-4B82-9921-946CB85B90E2@elecraft.com>

Hi all,

I should have sent this yesterday, but it?s not too late to get in on the action: It?s the CQ WPX CW weekend. This is one of the best contests of the year in which to work some new countries, test your antennas, try a new rig, etc. 20 meters, in particular, is really hopping.

The exchange is simple; just <RST> <sequenceNumber> (starting with ?1?). Full rules here:

   http://www.cqwpx.com/rules.htm

This is a great contest for QRP, because all of the big-gun contest stations worldwide are using their high-gain antenna arrays (which help with signal strength on both ends). 

I was out hiking using the KX2 and the AX1 20/17 meter whip prototype (4? long) today. Made about 10 contacts in 10 minutes with 10 watts (parallelism not intended :)  Best DX was Uruguay. 

73,
Wayne

John,

If the part costs $500, I don't know how you could get it repaired for 
$100!  Good luck.

Wayne said ~$100 for the LCD. Support claimed I had to buy the LCD and front
panel board together as 1 unit. I'm asking what is it?

 Yes, there is very limited space in that area so it's difficult to tighten that nut unless you have a very compact tool. My thinnest, smallest crescent spanner couldn't fit (much less turn) in that space, but rather than put the project on hold to find the right-sized tool, which in retrospect would have been the best course of action, I used a wrench to hold the outer (fixed) nut stationary while using the pliers to tighten the inner (free) nut.?The Elecraft tech uses only a pair of needlenose pliers in their Youtube video that demonstrates their recommended installation procedure.?

The multi-size spanner that KY5G suggested seems even larger, so likely would be too large to fit in that space. The problem is not so much thickness, but width. However, it is inexpensive and might be worth getting and trying. That torque wrench he suggested is probably small enough to fit and work, with its narrow "tuning fork" shape rather than a "crescent" shape, but at $115 is insanely expensive for something that I may only ever use again if I install a second transverter in my second KX3. I think what I'll do at this point is first see if I can find a suitable tool that isn't nearly that expensive.?

BTW, I am using a coax jumper to reduce torque on the connector, but my application is pedestrian portable, not base-station or "picnic table" portable.?

I appreciate the advice and the leads. I'll have to chew on this some before taking action.?

Thanks and 73, Ryan AI6DO

Thanks Wayne!!! 

 I am having a blast just with the KX3,  PX3, and KXPA100, what great designs!!!
The 20 M band is going great!!!
I'm just spending a few minutes here and there today and got through on the first try to UK, Finland, Slovak, and Czech.

Back to the radio.... 

Much Regards,
Dwight

Hi all,

I should have sent this yesterday, but it?s not too late to get in on the action: It?s the CQ WPX CW weekend. This is one of the best contests of the year in which to work some new countries, test your antennas, try a new rig, etc. 20 meters, in particular, is really hopping.

The exchange is simple; just <RST> <sequenceNumber> (starting with ?1?). Full rules here:

   http://www.cqwpx.com/rules.htm

This is a great contest for QRP, because all of the big-gun contest stations worldwide are using their high-gain antenna arrays (which help with signal strength on both ends). 

I was out hiking using the KX2 and the AX1 20/17 meter whip prototype (4? long) today. Made about 10 contacts in 10 minutes with 10 watts (parallelism not intended :)  Best DX was Uruguay. 

73,

Jack,

I just assumed you were throwing in an extra 8 db for the difference between a beam and a wire dipole.

Let me correct myself before others do. Its a 12db difference. And I will rib Bill about it. Still, to the west and north he has very high hills/mountains that block the RF path. Makes me wonder if he was using reverse path for the QSOs.

Good Evening,

 ?? One activity I mixed with radio was XC skiing in the Manzanos, a 
mountain range south and east of Albuquerque where they store nukes and 
supposedly some aliens on levels far beneath.? Pat and I would take a 
break from school and drive south from Tijeras? to some park land where 
the snow was deep enough.? With VHF simplex we could chat and ski.? We 
learned within a hundred yards not to use the VOX :)? When the snow 
wasn't too firm it was much easier to sneak up on the wild turkeys.? 
They can't run very fast in loose snow.? We were able to confuse a few 
does too.? We'd flank them into a boxed area and they'd have to choose 
which one of us to pass to get out.? Whispering on the radio was much 
more effective than yelling across a valley.

 ??? I got back into amateur radio because I wanted better comms for my 
robots.? But a few years later I had completed my thesis for an MSEE 
modeling a large number of antennas and using the data to train and test 
neural networks.? Two years of intense antenna study has come in handy 
building them for CW comms and other things too.? I still have dreams 
about Bessel functions.? Kind of like those I had before both physical 
chemistry finals.? You really can dream in five dimensions.

 ??? The sun has a few small spots on it with some solar wind.? We are 
due for a storm on Tuesday.? The solar flux is higher than I have seen 
it in quite some time: 76.? We may have better propagation tomorrow.
Please join us tomorrow on:

14050 kHz at 2200z Sunday (3 PM PDT Sunday)
 ? 7045 kHz at 0000z Monday (5 PM PDT Sunday)

Many cavers are also hams. We use 2M HTs for communication on 
the surface when project caving in Sequoia and Kings Canyon 
national parks. The WA6BAI repeater lets us coordinate with 
people in Fresno from near the cave entrance. We can let the 
cook know how many people are planning to come for dinner.

Over half of the NCRC cave rescue instructors are hams. Ham 
radios have been very useful in some emergency situations. For 
example see the President's Letter in: <http://wvara.org/het/Archive/heterodyne-2014-08.pdf>

We have also used QRP 80M radios for cave to surface 
communications. The radio in the cave had two random wire laid 
on the floor of the passage actin as an antenna with a tuner. 
This setup let us coordinate a cave radio demo showing how to 
locate the surface location directly over the transmitter in the cave.

More information about cave radios is in the back issues of 
Speleonics <http://caves.org/section/commelect/drupal/speleonics>.

Hi All,

Fascinating thread Wayne.

Most of my time now is devoted to design of electronics for a radio
telescope near Canberra in Australia.

https://en.m.wikipedia.org/wiki/Molonglo_Observatory_Synthesis_Telescope

Love my KX line though still a nervous nellie about CW.

Most of my life now is doing hardware and code for the PIC18F67K40 to
control beam formers for a telescope upgrade.

Cheers All,

Glen VK1FB (My call is a tribute to my mentor Doug DeMaw who I met in
Connecticut in the late 70s).

Message-ID: <2510B572-F7B5-4717-82B2-FA4BF4865B60@yahoo.com>

Using N6TV ?s ?Y-Box,? I can switch between the KPA500 or my new KPA1500 effortlessly as needed. However, regardless of which amp is active, the K3 message that informs you that the amp has been switched to/from stand-by to active always reads KPA500. 
For someone running amps in the same configuration remotely, this maybe an issue. 
Has anyone else noticed this? 
If so, have you determined a remedy?

Thanks,

I'm having a blast with my KX3.? I'm putting a serious dent in QRP DXCC 
this weekend.

I'm working EU on 20m normally with the 1st or 2nd call with 5 watts.

The KX3 has a great receiver and does not get wiped out with nearby 
strong signals.

Been using the KX2, with and without the KPA500 at times (the combo is good
for ~160 watts). 15m is currently open to EU - haven't seen that in a
while. Otherwise, wall to wall on 20m, day and night.

Windows has probably changed the COM port. Check in the Device Manager, by 
unplugging the rig, then re-plugging to see which COM port re-appears.
There's a way of preventing Windows from changing COM ports, but I forget 
what it is. Perhaps someone else can help, or maybe Google is your friend.

The CQ WPX contest is benefitting from an excellent opening on the high bands. I?m hearing WWV at 20 over S9 even on 25 MHz. CW contest activity is all over 20, 15, and 10 meters.

Get it while it?s hot :)  Contest goes on for another 8 hours.

You may also want to try going into Device Manager and disabling the COM 
port and then enabling it again.? I have an add-on serial port card in 
my computer and I have to disable and re-enable both ports every time I 
reboot or they will not work.

As a side note, I have a friend who had major issues with his computer 
after installing a Windows 10 update.? He finally found out that if you 
have Avast or AVG anti-virus software, it must be disabled before 
running the update.? Apparently it sees some of the update as malware 
and will put the computer in an endless loop of reboots.

Message-ID: <84B3E83B-BC0B-4D42-8DBB-396CE1FE2B5E@icloud.com>

I am trying to connect a 22? LCD TV to the P3 SVGA connection via the TV HDMI connection. I purchased a 9 pin serial to HDMI cable but the P3 does not appear to see it. I switched to the 2nd HDMI port on the TV, but still no joy. I have enabled the SVGA monitor option in the P3 menu settings also.  Any suggestions?

I do see on Amazon that I can buy a 19-22? LCD monitor for about $100...

Mark,

I could be wrong but I think there's a bit more electronics
needed. You can search for VGA to HDMI
converter - also on Amazon.

They seem to be around $10 to $15.

The P3 has a 15-pin connector (5-5-5 pins per row) for SVGA which provides an analog video output.  It is not a 9-pin serial output as you mentioned above.  The 9-pin RS-232 serial ports located next to the SVGA port (if installed) the P3 are for interconnecting the P3 to the K3 (?XCVR?) and Personal Computer.  So the first thing to check is to ensure that the SVGA video port is indeed installed.

On-the-surface, it appears you?ll need a SVGA-to-HDMI converter to convert an analog signal from the P3 to a digital signal compatible with HDMI.  SVGA was initially defined as  1024 x 768 8-bit resolution, but the P3 P3 SVGA adapter can handle up to 1920 x 1080 resolution (See: ?P3SVGA Option Installation and Operating Instructions? p. 3 that is available on the Elecraft website) so make certain that whatever device you purchase is compatible with the resolution levels of the P3SVGA.

But with what kind of video interface does it have: Is SVGA available or only digital (DVI or HDMI)?

Hope this helps,

Mark,

The P3 SVGA adapter will not support all VGA displays (but it will do 
most).  There is no guarantee that a VGA to HDMI converter will work, 
but you are welcome to try and report those which do work as well as 
those that do not.

"Down-conversion" is no problem, but make sure that the adapter is one
for converting S/VGA to HDMI and not the reverse. There are several
available from "the usual sources".

A rant of the day:

But, there is a big looming question ? one I had when the SVGA feature was released.  Why wasn?t it directly an HDMI interface in the first place.  Today, finding a good display with the latest features that still supports SVGA is a no-go almost.  I believe that was probably the case when P3/SVGA was released too or they were at least on equal footing.  Let?s face it, flat screen TVs changed everything.

There should be an HDMI interface option made available for the P3.  I have not yet bought the SVGA and I probably won?t because my only spare 20 inch display (I use as extra display for iMac at times and also with RPi) is HDMI and DVI capable but not SVGA.  No plans to buy a converter cable either.

My RPi has HDMI chip on it ? the entire RPi board is only $30 so the chip itself must be cheap ? just looked up on Mouser, TI HDMI interface IC in units of 250+ is $2.82.  Of course, there is more cost then the chip but still, I am betting on equal terms with SVGA costs.

OK, I am climbing down from the rant bench.

Phil,  I too have not ordered an SVGA adapter for my P3 as my 4K display only supports HDMI inputs.  I have hopes that Elecraft will offer an HDMI adapter in the (hopefully near) future.

The eSynic VC043 (available from Amazon for $12.95) works well with the P3
and a HDMI monitor. The one thing you will need to do is supply 5 Vdc to
the USB plug on this unit. The USB on the back of the P3 does not work to
provide power to this unit so you will need another source like your
computer.

I brought this issue with the lack of power with the USB on the P3 up in
another thread a few days ago and have not received any response.

Subject: [Elecraft] K3S Won't Power Up / Obvious Things checked...
Message-ID: <CAFYRpHtp=OyhgBLwEh-mUHU-7i=LMe5M91RBp6eqsCFQ9dwFUg@mail.gmail.com>

Hi, this morning I got off on a tangent (when I should have been running
JA's in the WPX contest on 40m at 6 points a Q!).  My K3S has been powering
back on right after powering it off.  As I was diagnosing things and
removing the ACC connection etc... on one of the power off attempts it
stopped coming on at all??  I reverted to my backup K3 and finished my
lackluster effort in the contesting and now I'm scratching my head over the
K3S not powering up.  If I removed the acc connector the K3S would stay
powered off... and I don't have anything on pin 8 for the remote power
on... anyway, the bigger issue now is that I can't get it to power back on.

I checked the obvious stuff like the breaker on the back and then pulled
out the KPA100 and removed the bottom panel to poke around and check the
polarity protection diodes.  I'm not seeing anything obvious and the diodes
are fine,  I'm getting voltage to the mosfet source pins 1,2 and 3 on
switching package U2 (DMP4015SSSQ)... the typical diodes along that path
check out fine from what I can tell where the drain pints 4,6,7, 8 send
power to the external 12v RCA jack on the back of the K3S.  However
pressing the power button doesn't seem to be charging the gate on the
package and there is likely some other circuit in the mix anyway.

I also tried the 10 second power button hold to get into the MCU boot
loader mode, thinking something got jacked up on one of the power off power
on cycles and I need to reload the firmware of something... nothing...
There is no life at all or any indication of power in the front panel
etc...  It's a sick little puppy!

If anyone knows something I couldn't find via google, I'm all ears, and
I'll fire off an email to Elecraft support and ship it in for service.  I'm
not sure I want to get too crazy chasing thing down from the front panel
all the way though.

Thanks for reading.  Max NG7M

Do like I did, go to your hardware emporium, buy a cheap correct size
wrench.  Go home and turn the bench grinder ON. The result isn't pretty but
works fine.

Dear Ryan,

in order to avoid the torqueing or breaking the SMA I can recommend to use
SMA coaxial jumper.
https://plus.google.com/100312042524727617304/posts/b4hvsciD3qG?hl=eng
...available on eBay, but be careful to get high quality only, PTFE
recommended.
Never use adapter or even set of few adapters directly.

A similar problem has happened to VNWA users on Windows 10 upgrades.? USB Vodecs are still in the registry, but Win10 upgrade set them to "DISABLED".
You should try an app called USB View:? https://docs.microsoft.com/en-us/windows-hardware/drivers/debugger/usbview
Use this reference to generally tell you how to find and enable the Codecs:
No VNWA sound devices detected after upgrade to Windows 10 feature release 1703? <--- I suspect it will happen on every major release

http://sdr-kits.net/documents/VNWA_Sound_Devices_error_after_Windows10_upgrade.pdf
You might also open Windows Device Manager and select View --> Hidden Devices to see if it is there.

Windows+R, type devmgmt.msc then ENTER.

Either way, you'll need to know WHICH USB Cdec was the one your K3s was using...? Windows has a habit of creating a separate one for each USB port the device is plugged into.
I have started editing the names of the USB Codec entries in Sound Manager so I know which is which.

Hope this helps...

I resumed contest operation after modifying my SteppIR  driven element length for 20 m band.   With KPA500 indicating 1.3:1 (LP-100A 1.38:1) I saw no more PA DISS faults.


If I had known that the KPA500 was this sensitive to load impedance I would, perhaps, have purchased the KAT500 tuner.  However, I found nothing in the documentation that suggested the KPA500 would fault frequently with a reported SWR of 1.4:1 and with power and SWR never peaking in to the amber regions.

Subject: PA DISS fault and relationship to SWR


Up until this weekend I had experienced 3 PA DISS faults with my new KPA500.   I provided data to Elecraft and, after a fairly long and informative email exchange, I was told the fault is very rare and most likely caused by some problem at my station.

I developed a 10 frames per second data logger which polls and records data from the KPA500 serial interface as well as the ALARM signal available on the AUX port.  The ALARM signal was also used as a trigger so that 'scope data could be time correlated with the logger data.   CQ WPX CW contest seemed to be a good opportunity to gather data if the fault could be reproduced.   After experiencing 5 PA DISS faults on 20 meters I abandoned the contest, looked at the recorded data, and ran some additional tests.

The data show that PA dissipation (DC input power - RF output power) is strongly dependent of load SWR.  That in itself is probably not surprising.   What was surprising was that my KPA500,  when operating into an antenna load that the KPA500 reports as 1.4:1 SWR, has a PA DISS of 500 W when producing 400 W output.  What was more surprising is that, although the PA DISS fault is designed to trip at 400 W ("The PA Diss uses non-averaged data to do a comparison between the calculated power from PA voltage and PA current and the measured output power. If it is more than about 400 watts on four consecutive checks (each 8 mSec apart) then we declare the fault.") it did not trip for a key down test lasting several seconds.

Sample data for different load condx shown below.  None of these key down tests resulted in PA DISS fault.

Can someone at Elecraft please explain why PA DISS fault does not trip when key down PA DISS (calculated from WS and VI serial data) exceeds the 400 W threshold defined for this fault condition.  When the PA DISS fault was seen in the contest it always happened during the first element of the CW transmission.


Raw logger data, Excel data, and scope traces have been saved.  KPA500 firmware is 1.54.

Thanks for the reply.  Please note that I have no issue with high SWR faults.  I have seen several FAULT 09 REFL HI events and they were all caused by an operator antenna switching error.  PA DISS (FAULT 11) is not an SWR fault although it appears it can be induced by a load mismatch.

Yes, I did understand that Andy.? My GUESS was that the PA-DSS (efficiency) is sensitive to the actual load impedance.? I suspect that the SWR fault, that I sometimes see, is also sensitive to low vs high impedance.

First major contest with KPA-1500.  Overall VERY pleased.  No glitches
other than a few operator errors early in the contest.  Loving the amp.

Fan noise...another issue.  Usually for a cw contest I use some old ear
buds.  Not possible with the amp.  Had to use the total ear muffs and still
quite noisy.  Did not effect my performance but it is annoying.  I can not
imagine what it was like before they released the amp to general public
when they changed the fans...made them less noisy???  Still needs some work
but at this point probably not possible.  So looking for suggestions for
reasonably priced noise cancelling headset with mic if possible.

Hope we get full explanation of what gets changed in the next firmware
release.

Still smiling.

 I'm thinking there will be a firmware update to fix this.? I don't have a Y box but the only menu choice in the K3 is kpa500 and that is what I see from the 1500on the K3 display although it might already be fixed as I haven't upgraded firmware in a while.

 Using N6TV ?s ?Y-Box,? I can switch between the KPA500 or my new KPA1500 effortlessly as needed. However, regardless of which amp is active, the K3 message that informs you that the amp has been switched to/from stand-by to active always reads KPA500. 
For someone running amps in the same configuration remotely, this maybe an issue. 
Has anyone else noticed this? 
If so, have you determined a remedy?

Thanks,

 Yeah the fans are pretty noisy especially when CQing without answers which keeps the amp duty cycle high.? At least when you get answers the amp has a chanceto cool just a bit and keep it below 70C which is where the hyper drive fans come into play, hi.? I'm still happy with the amp for several reasons but I still prefer tube amps.I thought I would have two Acom 2000a's but when I saw the new 1500 I figured I would take the solid state plunge for instant on capability but I still prefer my 2000.Tube amps have the same speed fans no matter how hot and how many CQ's you call.? The 1500 sits on top of the Acom quite nicely though, that couldn't happen withtwo Acoms, hi.
A friend of mine keeps his amps in the basement with his shack upstairs.? He is awaiting his 1500 to return from Elecraft for a repair but I already emailed him and toldhim he definitely would like to remote the 1500 to the basement, hi.? I could use the Acom more for running somewhat but I was giving the 1500 a pretty rigorous testover the weekend.? I don't know how well noise cancelling headphones will do with the 1500 fans when they start singing over 70C.? I keep the manual speed to at least2 while contesting and sometimes 3.? It helps to get the temp to stay lower for longer periods while the duty cycle subsides.? First big contest test of the 1500.

No KPA1500 here but I did replace the fans on my lil' ol KPA3 with 
Noctuas. They are noticeably quieter. If there is a suitable Noctua 
replacement for the KPA1500 fans you might want to compare the sound 
level specs to the Sanyo Denkis.

Wonder if it would be possible to build an active noise cancelling 
system into the rig itself; seems like it would work in that enclosed 
space...

Although making things a bit larger physically, fans enclosed into the 
equipment case, thus providing some acoustic dampening, and configured 
to pull air into the case {along with much of the noise} and exhausting 
air and noise through several ports is more applicable to reducing 
overall noise.? High volume air moved at slow rates is much quieter than 
the same amount of high volume air moved at faster rates.??? Also, fans 
with a lower blade tip velocity makes less noise.

As I indicated in an earlier post, some fans are more efficient at 
"blowing" i.e pressurizing the enclosure, while others are more 
efficient at "sucking" thus evacuating the enclosure.? In general, sound 
moves with the air flow.

Subject: [Elecraft] OT antenna question
Message-ID: <50BD29C0-FFD5-45AB-BE7D-788CA5D24F24@mac.com>

While off topic this antenna supports an all Elecraft station.

I have very limited antenna space and my 80M/20M shortened dipole consists of 17? center sections connected to approximately 44uH, 2.5? OD inductors with 10? end wire sections past the inductors and terminated in end insulators.

The center sections of the dipole are tuned for resonance at about 14.15 MHz and the end sections, past the loading inductors on each dipole leg, are tuned for resonance a 3.7 MHz.  The resonance dips at both frequencies are quite sharp and the SWR on both bands is less than 1.5 to 1.

The question that I can not get my head around is this.  On 20M the two inductors are acting as chokes and not traps but I have no idea what the losses might be with these chokes acting as end insulators rather than a trap or actual insulator.

In actual operation the antenna works quite well on both bands but I would like to get an idea on how efficient these inductors are when used as chokes (4,000 ohms) on 20M.

Subject: [Elecraft] K3 SSB +CW Power Overshoot
Message-ID: <163a7a2f7c2-c8e-15c82@webjas-vaa168.srv.aolmail.net>


I have just attempted the K3 SSB +CW configuration for the first time.?
 Unfortunately, behavior is not quite as expected; I experience a
 substantial CW carrier overshoot on first key press and after a subsequent
 mode change. (Mode change can be a band change or an Operate/Standby
 change when running with the KPA500).?

 The overshoot is on the order of 10 to 40% depending on the power level
 setting.?

 When running the K3 barefoot at 100 watts the overshoot is on the order of
 110 watts measured with a W2 in peak reading mode.

 When running the KPA500 set for 500 watts (approx 27 watts drive), the KPA
 output overshoot has been observed to exceed 700 watts triggering a high
 power fault. The only recourse is to reduce drive setting to the KPA500 to
 an output level of 400 watts or so where the output power overshoots to on
 the order of 550 watts.

 Holding down the key after the overshoot, the power settles to the selected
 value in a second or so (assuming KPA power is set such that no fault
 occurs).?

 Subsequent CW key presses produce power output at the selected value without
 overshoot, regardless of momentary or continuous key press.?

 Also observed is difficulty setting power on key down, particularly with the
 KPA500. Power setting is "jumpy" when changing power, after the overshoot
 has stabilized. It seems as if when increasing power, it overshoots the set
 value, then drops to the set value.

 The issue is observed on all bands and on upper or lower sideband.

 I've performed TX Power Calibrate several times with reported success, but
 no change in overshoot behavior.

 When in normal CW mode, there is no overshoot and the power adjustment is
 smooth and stable.

 The SSB +CW mode would be quite useful if it was stable, but I am uneasy
 using it as currently implemented. Any comments or ideas are welcome.

 K3 is S/N 4457

Hi Mike,

An EZNEC model using 30 feet AGL and Q=200 for the coils, has a very
close match the the reported values.

20M, the antenna does not seem to degrade form a simple dipole with a
Gain of about 6 dBi at about 30 degrees elevation.

80M, it's about 5 dBi at 90 degrees elevation. Expected from a low
dipole. The impedance at resonance is about 25 Ohm, so should have a SWR
about 2. A lower measured SWR may be the result of other system loses.

I'd suggest this antenna is a good option for the constraints imposed.

I've seen no documentation on this output. I assume it is a tap on the PA
output before the ATU.

Does anyone know the expected level here? Is is 30 or 40db or more down
from the PA out?

Is the attenuated level flat with frequency?

I just upgraded my KX2 to v2.89 firmware, and discovered that I can no
longer get the "SWR/RF" scales to display when I transmit in any mode.
Perhaps I missed a release note that described this change, but I seemed
to remember that these scales were the default, and that the CMP/ALC
displays only appeared when setting transmit gain.

What am I missing, or have I found a bug?

Andy,
Pick up a copy of the DVD "North Atlantic Crossing".  Two young men used
what appeared to be an Icom HF rig for long distance communications on HF
air bands to contact various European airports on their route to Norway.
They installed a large, salt water fishing reel in the modified, single
engine  Mooney, complete with stranded copper antenna wire.  When time to
use an HF band, they cranked out just enough (pre-marked) wire from the
fishing reel to hit the resonant frequency.  I can't recall where/how the
antenna wire exited the aircraft but got the impression that, among other
mods (extra capacity fuel tanks, etc) the antenna device was approved for
that flight.

"Drag a wire behind you like they tow banners."


If it were as simple as you suggest then I think a few of us would be doing
it. Picking up banners with an aircraft in flight is a skill that most
pilots don't have. It would be far better to use a retractable antenna.
However, a legal installation of any sort of antenna extension/retraction
mechanism on an aircraft with a standard airworthiness cert would be a
significant challenge.


(No banner experience but I do have lots of time towing gliders and flying
jumpers)

Message-ID: <7362dea2-935f-f3b5-6f22-361211216658@shaw.ca>

I'm on the list for a '1500, expected sometime in August (maybe). 
However, I'm getting concerned about the reported high fan noise level.
I currently have a '500, and following a suggestion a year or two ago, 
I've turned the fans around 'backwards' and they seem to be quieter in 
this configuration. I would give the '500 a "quiet" in the noise 
department. Temperature does not seem to be an issue.

In addition, I have an Acom 1000, which is also a quiet amp - fan as 
well as relays. Hard to hear it in operation (but the 3 minute warmup 
usually seems like three hours. :-)

I ordered the '1500 In the quest to be a couple of instant db louder, 
but if I don't hear some resolution of the noise 'problem', I'm going to 
put the order on hold until it is solved. I do have many headsets which 
I usually wear, including the Bose QC15 noise cancelling model, but I'd 
hate to be FORCED into using them.

Dan,

I experienced a similar issue with my K3, S/N range 4,000.  I attempted a TX
Gain calibration with minimal improvement.  40m and higher bands (in
frequency) worked OK (no overshoot) while lower bands still faulted.

I finally performed an EE INIT, reloaded 5.60 firmware, and the last saved
configuration.  I later upgraded to the beta 5.64 firmware.  Neither
firmware version resulted in overshoot after the EE INIT.  The rig has
operated normally over the last week.  I can now rest without worries (about
the K3 and its performance at the upcoming FD).

Save your current K3 configuration and try an EE INIT.  While not logical, I
did this twice before I achieved success.  GL!

73, Bill, K8TE

Kevin,

Having spent "quality time" in the Manzano Mountains area surrounded by very
secure fencing, cameras, sensors, armed guards, etc., I can tell you there
are no nukes there today and there were no aliens (from outer space) in
those facilities.  If I told you anything else, I would have to take your
keyboard and birthday away.

Interesting! Sounds useful on 6m, for example, when running a contest SSB above 125 and there's a difficult Q where the guy's having trouble with an exchange element. Generally running an amp, so overshoot would be a problem. 

Thanks for info.

My KPA1500 seems to max out at about 65 C when running and calling CQ.? 
At that temperature, the fans are just barely audible with the 
Radiosport headset.? That would be way too loud for me with any other 
headset I've used, let along a speaker.? While it has other big 
advantages, the noise level is about as bad as that of my old AL-82.? Of 
course, the KPA1500 could be located in another room.

Well, I manually set the fan to 2 when I?m going to use the amp heavily. It?s a bit noisy but acceptable to me.

I'm amazed that such an eclectic group has so many similar experiences in
which I am included:  flying, NAVAIDs, boats, trumpet, bass in choir, etc. 
Adding to the ILS story, while stationed at Canon AFB NM, I also worked
full-time as a TV broadcast engineer.  I was part of a team that installed a
new FM station at the same location.

Shortly after that, I got word at the Communications Squadron Chief of
Maintenance office where I worked of F-111D pilots experiencing country and
western music on on runway's ILS approach.  The FM frequency was 107.5, just
below the ILS localizer band.  My Chief and I stook a giant RADAR spectrum
analyzer (two-man carry) to the FM TX site.  As expected, it was clean.

Next, I visited the Avionics shop to put a USM/323 RF signal generator on
one of the F-111 ILS receivers.  With a 105.5 FM modulated signal, the ILS
RX lit up!  It was as broad as...!  The least expensive solution was to move
the ILS (Localizer and Glideslope since they're related) to a new frequency
pair.  That meant new antennas, phasing lines, alignment, etc.  I'm certain
it cost more than the new RCA FM transmitter and antenna/feedline, but was
"easier" to accomplish.

BTW, an HT and helmet-mounted headset work pretty well in sports car racing. 
However, I never tried to add HF mobile to my Spec Miata, much less try CW
while on the track!  I have some interesting in-car video recordings of me
calling my wife after some "incidents."  73, Bill, K8TE

While SWR and driving Z values may be correct, there was an excellent 
piece 2-part piece in QEX 3-4 years ago showing that NEC does not 
correctly model phase shift through inductors, thus producing wrong 
answers for field strength (i.e., how well the antenna WORKS). This is a 
shortcoming of the NEC code, and is unrelated to the user interface like 
EZNEC/ELNEC and 4NEC2.

The antenna he was studying was a loaded mobile whip for HF. The first 
part of the article was a serious engineering description of the test 
setup, including the measurement system. The second described a 
carefully controlled study, using that measurement system, of inductive 
loading at the base, midway, and fairly high on the vertical radiator, 
as well as capacitive top loading. He compared measured results with the 
NEC model. As I recall, differences between modeled and measured data 
were as much as 10-14 dB for bottom loading.

In addition to exposing the limitation of NEC, the major conclusion from 
his study was that because radiation is produced by current and current 
is greatest near the feedpoint, a design that provides the greatest 
vertical height before the loading element(s) will generally be the most 
efficient (that is, produce the loudest signal). Those who have long 
been serious about HF mobile antennas have known this for years. At 
least as long as 20 years ago, W8JI has written a lot about this. In 
that time frame, my buddy K9IKZ told me about an annual conclave of HF 
mobile station builders convened in southern Indiana to do "shootouts" 
of their designs.

This is exactly one of the many issues that Acoustic Consultants address 
in the design of buildings that house recording studios, concert halls, 
and student practice halls in music colleges. I regularly worked with 
world-class guys in my own consulting practice, which only did sound 
system design, and I learned just enough to know that I shouldn't try to 
do their work. :)? There are many elements to the design problem, and 
the fan itself is only one of them. Other elements I'm aware of is 
turbulence of air flow, mechanical vibration coupled from the fan to the 
structure to which it is mounted, where the fan(s) are located, and so on.

I don't know if one of them was involved with Elecraft, but if not, I'd 
suggest that Elecraft buy some time from one of them. And I'd be happy 
to provide names of some good people/firms. In the early K3 days, I 
referred a good acoustics guy to Wayne to solve the problem of acoustic 
coupling between the speaker and the synthesizer that added a sideband 
to RTTY, and suggested adding the stiffener to that board solved the 
problem and became a running mod.

Good discussion.  For giggles I ran sound meter at my op position.  About 1
ft below where my head would be so readings would be higher at head level.
Fan Speed   Level (db)
1                  50
2                  59
3                  65
4                 70
5                 75

So it is going to take some good headsets to help significantly.

Hi Jim,

The TX SAMPLE output is supposed to be described in the owner?s manual. If it?s not there, it will be in the next update. It?s also mentioned in the FAQ, but re-reading it, I?m not sure it describes the signal level accurately. I?ll check on that.

You have to be in a mode other than CW, then tap the KYR-SP/MIC knob to 
switch between CMP/ALC and SWR/RF.? Enjoy!

Mark,

This, too, appears relevant:
 
   https://www.silabs.com/community/interface/forum.topic.html/cp210x_driver_v101-91Gl

It specifically mentions amateur radio gear, though it?s specific to SiLabs parts. I?m not sure off the top of my head whether it applies to the USB hubs/codecs we use.

A Google search for 

   "com port"  Windows 10 update

turns up numerous complaints about how the latest package has broken comms, including USB, BT, parallel ports, etc. All parties claim they?re ?working on it."

I don't have a fancy schmancy degree in acoustic design, but in my 20+ 
years of thermal control design for computing and other electronic 
products, I necessarily dealt with acoustic design as it pertains to 
device chassis.? They are often competing demands.
One of my main selling points to many of my clients was that while 
meeting their requirements for thermal control, I could generally 
improve (reduce) the acoustic stress on their staff.? I had several 
long-term relationships where they kept adding adjunct projects to the 
original contract that were primarily acoustic and only secondarily 
thermal control as a result.

I'd be happy to trade some "free thermal/acoustic" analysis time on the 
KPA-1500 in return for the simple pleasure of having one on the bench 
during the process.? <big grin>
Assuming I can produce a viable/economically feasible solution for both 
the company and customer base, perhaps a deal could be reached on a 
price to avoid returning the "test bed". <bigger grin>

Wayne?? Eric?

There is no license fee for NEC2, and EZNEC and 4NEC2 both use it freely.

NEC4 is another matter ...

Any chance you have the ability to capture and send me spectrograms at 
each fan setting?? I'd like to get some appreciation for the frequency 
and amplitude "manifest".
One of my amateur radio mentors just received his KPA-1500, but he's 
recovering from triple bypass in the hospital, so I can't even get a 
good look at one...? At least I could get some exterior high res images 
and relevant dimensions.

Also, can someone send me the precise make and model of the fans being used?

73,

Thanks for the offer, Clay. But we actually did extensive thermal analysis of both the heat sink and fans, tested many different fan types and configurations, and did comparative noise testing of the KPA1500 vs. a number of other amps. 

As you allude to, there?s no magic bullet. Heat must be removed, with various physical and electrical constraints to be satisfied. 

We have some pretty amazing thermal imaging devices that we use to examine heat signatures of electrical components. These were used during R&D, which is how we determined that two LDMOS devices were far better than one for heat distribution. We also used it to evaluate the design of our very large/very thick copper heat spreader. On the production line, we review all modules for hot spots during burn-in and make sure the cooling is working perfectly (onset temperature, air distribution around modules, etc.).

Of course supplemental cooling of various types has been used with amplifiers in the past. I believe we have a couple of customers and staff experimenting with this idea, and anything that emerges will be posted here.

My mistake... doh!? I meant 4.

Increment version by 2... same question... Does NEC-4 handle the phase 
shift through inductors correctly?

It's a big chunk of change to get the NEC-4 license and upgrade the 
front end license...? need to compile multiple reasons to justify it.? 
<wink>

Appreciate the catch...

My pc just updated with the April update.

I do not have a P3, but comms between my pc and my K3S are still good.
In my case, the K3 Utility runs on COM3 using an FTDI driver.

K3 Utility 1.16.7.25
K3S # 11310, MCU v05.57.
Windows FTDI Driver 8/16/2017, v2.12.28.0

Mark,

This, too, appears relevant:
 
   https://www.silabs.com/community/interface/forum.topic.html/cp210x_driver_v101-91Gl

It specifically mentions amateur radio gear, though it?s specific to SiLabs parts. I?m not sure off the top of my head whether it applies to the USB hubs/codecs we use.

A Google search for 

   "com port"  Windows 10 update

turns up numerous complaints about how the latest package has broken comms, including USB, BT, parallel ports, etc. All parties claim they?re ?working on it."

Clay,

NEC-2 is public domain.? NEC-4 is not, it is licensed and not free.? I 
believe that all flavors of EZNEC Ver 4.0 EXCEPT EZNEC/4 use the NEC-2 
engine.? NEC-2, as a simulator, has some deviations from reality ... 
inductor modeling is one of them, conductors connected at small angles, 
traps [see inductors] and modeling buried radial fields are others.? 
NEC-4 is significantly more complex, more faithful to reality, and not free.

The native UI to NEC-2 is not friendly, it's origin dates to 80-column 
punched cards.? EZNEC is a windows UI to it.

K3s is on COM port 7 using the latest FTDI driver (v2.12.28.0)

Hi,
The first thing I would do at this point, is to go into the device manager 
and select "Properties" for the driver.  Next select the "Driver" tab and 
then click on "Uninstall Device" and  Make absolutely sure that you select 
"Delete the driver software"

That will get rid of it.
Next download the appropriate drivers from the Elecraft site or use the link 
for it.  Unplug your USB cable to the radio, install  and only plug in the 
cable when directed or the install is complete.
Never do an "Update Driver".  In many cases Windows will substitute a 
universal driver that may not do what you want.

Now with the latest Windows 10 update, some changes have been made to the 
Privacy settings on your computer, specifically devices that act as 
Microphones, one of which is probably the USB codec that Elecraft uses. 
Make sure it is set to allow.

With the latest Windows 10 update earlier this week, my K3S and P3 can no

Device Manager and right clicked on the COM12 device drive and clicked

Tom,

Earlier today I did delete the driver as you describe, but I did not know there were drivers on the Elecraft website. I?ll check it out tomorrow. 

Thanks for the suggestion.

Subject: [Elecraft]  KPA1500 fan noise concern
Message-ID: <002201d3f6ea$4bb77210$e3265630$@com>

I imagine that due to the KPA1500's size it requires a higher volume of air
than a large amplifier would. Its small size and weight make it appealing.
The Acom 2000 has a control box that is separate from the amp so you really
never hear the amp run. I am wondering it something similar can be done with
the Elecraft KPA1500, perhaps an option like the K-Pod, so that the noise
source is further from the operating position?

John KK9A



Thanks for the offer, Clay. But we actually did extensive thermal analysis
of both the heat sink and fans, tested many different fan types and
configurations, and did comparative noise testing of the KPA1500 vs. a
number of other amps. 

As you allude to, there's no magic bullet. Heat must be removed, with
various physical and electrical constraints to be satisfied. 

We have some pretty amazing thermal imaging devices that we use to examine
heat signatures of electrical components. These were used during R&D, which
is how we determined that two LDMOS devices were far better than one for
heat distribution. We also used it to evaluate the design of our very
large/very thick copper heat spreader. On the production line, we review all
modules for hot spots during burn-in and make sure the cooling is working
perfectly (onset temperature, air distribution around modules, etc.).

Of course supplemental cooling of various types has been used with
amplifiers in the past. I believe we have a couple of customers and staff
experimenting with this idea, and anything that emerges will be posted here.

I just wanted everyone to know that the latest www.W4NJA.org <http://www.w4nja.org/> May Monthly Meeting/news letter has just been published.  Oh, if you haven?t subscribed to this ?free? publication, I highly recommend it.  Subscription info is at  bottom, right hand side of page.

I talked with Malckom Williams tonight in his hospital room at Lourdes Hospital, room 323.   His surgery went well except he had to have a lot of skin grafted from the other leg to cover the stump.  This will necessitate an additional 10 days in the hospital.  However, he is very upbeat and cheerful. He realizes that he is getting the very best of care.  In fact, he said that he is doing so well that he may be able to walk out of the hospital with the aid of a cane.  He doesn?t have internet facilities but I?m sure he would welcome a phone call.  Lourdes switchboard: (270)444-2444.

Don?t forget the KY QSO Party.  Check the KYQP web site <http://www.kyqsoparty.org <http://www.kyqsoparty.org/>> and Dave?s recent detailed email for information.  I?m requesting all participants take pictures (use iPhone, Samsung, etc. small size pix) of your station in action, include info and mail to roncowherd at aol.com <mailto:roncowherd at aol.com>.  I?ll prepare a slide show for the next meeting.

Princeton Ham Fest, June 2nd.  The Princeton Hamfest will award the ham radio club with the most members in attendance, a check for $100.00.  Please share and help spread the message. 

As you return from the Princeton Ham Fest:  Ron, Ken and Jason request your presence at our portable KYQP site, in the LBL.  (only a few miles off of I-24) We will be operating at the overlook on the trail just past the canal (first marked, paved one lane road (one way) to right as you drive into LBL from Grand Rivers on The Trace.)  After turning onto the Overlook Trail you will see a paved parking area and 2 picnic tables in a clearing large enough to put up an inverted V fan-dipole that we will be using.  (80-40-20?15 mtrs.)  We expect to arrive there about 8:00 to be ready for the 9:00 start.  Paul Smith tells me that this is in Lyon County, code  LYO,  EM56.  We hope to see as many of you that can stop by.

Brian:

That's the first thing I tried.

While in USB/LSB or AM, tapping the KYR-SPOT/MIC knob toggles between
"13 WPM" and "MIC 30" on the VFO B display, but does not change the
meter to SWR/RF.

The next clue is that I do see the SWR/RF meter when in CW mode, but not
in USB/LSB nor in AM. When I tap the KYR-SPOT/MIC knob in CW mode, the
VFO B display shows "SPOT" and a tone is heard through the speaker.

This has happened to me often enough that I should have learned to read
my manuals cover-to-cover, which I never do: A feature I had no use for
became inadvertently activated, and sabotaged my normal operating modes.

In this case, it was the CW-in-SSB feature, which apparently deactivates
the RF/SWR meter in SSB mode. It's described on page 45 of the most
recent manual.

Message-ID: <CACU_DC9EK-Y0Ykeyvo2bfnHcDozw7xvs6sOSZUuT+WDPvX-R7g@mail.gmail.com>

 I am using the KX3 with SDR play as a pan adapter. I have noticed that
there is some type of signal (quite strong) showing up on the pan adapter
on the frequency that the KX3 is tuned. This signal moves as I move the
VFO, so it seems to be some local oscillator issue. The result is the sdr
play seems to be desensitized and signal levels on the KX3 are lower. When
I engage the RX pre-amp, this signal goes away and all is right with the
world. On most bands 10 db is enough to do the trick. On 17 meters it takes
30 db to get rid of it and remove the desensitization from the RX. Wonder
if anyone else has seen this working with an SDR play and KX3? I have the
2.9 firmware installed. Thanks...Fred, WD5F

Message-ID: <CAEhYShJTUKo2rUOUj9hzwUrmwya84Cv+1asV5rQc42MqS4mPDw@mail.gmail.com>

Hi all,

Question here, I can't seem to find the answer to in the manual or with
google. Is the power cord that comes with the KX3 a special part for
Elecraft or is that a common "electronics distributor" part?  The manual
states a Switchcraft part number, but that part is for a standard straight
plug, not the molded 90 degree plug that comes with the radio.   I'd like
to purchase more of these plugs for various places/power sources and would
like to find an exact replacement so I can use some of them with the 3D
printed coax-to-powerpole adapters that are out there.

If the answer is "order it from Elecraft", that's acceptable, but if there
is a generic part number I can buy at the same time as other parts I need
(ie, mouser, digikey, etc) that would be good to know.

Thanks everyone.

Turn on MENU:RX ISO on the KX3. This turns on a isolation amp to keep the LO frequency out of the antenna input.

The KX3 is a direct conversion receiver and some local oscillator signal makes it out the antenna connector. The LO is at the carrier frequency of the tuned signal.

You need to use the 10 dB isolation preamp. That is designed to reduce that radiated RF.

This is also a good setting for Field Day with multiple rigs.

As I have found, it may be necessary to set the LO to an offset value 
from the TUNE frequency of the SDR Play receiver.?? I use HDSDR for my 
software with the SDR Play.? The feature is in? the F7 Options menu, 
look for Misc menu options of HDSDR.?? Also, it may be necessary to set 
the DC Removal to a value in F7 Calibration menu. A bandwidth of 5 to 25 
Hz seems to work OK.

When we next release K3 firmware, the message flashed on VFO B will be ?KPA*500?, intended to convey that either a KPA500 or KPA1500 is connected. At present the K3 doesn?t distinguish between the two, since they?re identical as far as operating state and error messages are concerned.

I would imagine the 1500 will be remotable just as the 500 is.? A friend of mine remotes his 500 to the basement just as he did with his Acom 2000aand he is investigating remoting the 1500 he just got.? As for a control box I don't know.? Not sure if the amp faults will be visible in the vfo B area ofthe K3.? It tells you its on-off or in standby.

 I imagine that due to the KPA1500's size it requires a higher volume of air
than a large amplifier would. Its small size and weight make it appealing.
The Acom 2000 has a control box that is separate from the amp so you really
never hear the amp run. I am wondering it something similar can be done with
the Elecraft KPA1500, perhaps an option like the K-Pod, so that the noise
source is further from the operating position?

John KK9A



Thanks for the offer, Clay. But we actually did extensive thermal analysis
of both the heat sink and fans, tested many different fan types and
configurations, and did comparative noise testing of the KPA1500 vs. a
number of other amps. 

As you allude to, there's no magic bullet. Heat must be removed, with
various physical and electrical constraints to be satisfied. 

We have some pretty amazing thermal imaging devices that we use to examine
heat signatures of electrical components. These were used during R&D, which
is how we determined that two LDMOS devices were far better than one for
heat distribution. We also used it to evaluate the design of our very
large/very thick copper heat spreader. On the production line, we review all
modules for hot spots during burn-in and make sure the cooling is working
perfectly (onset temperature, air distribution around modules, etc.).

Of course supplemental cooling of various types has been used with
amplifiers in the past. I believe we have a couple of customers and staff
experimenting with this idea, and anything that emerges will be posted here.

Tom,  I get prereleases for WIN 10 Pro which means I got the release you are probably discussing in this thread some time ago.  The audio codec changes in the release can be a big PITA.  I have to unplug my USB cable to the K3S in order not to have the PC speakers and the directly plugged in Stereo speakers on at the same time.  If I want to use the USB cable, then I have to use the PC speakers.  Interestingly, I can disable one set of speakers via control panel settings, but once I reboot the speaker is then re-detected.  I will eventually have too use the PC speakers, and abandon my excellent stereo speakers hooked directly to the K3S.  I prefer using the volume control on the K3S vs reaching to adjust the PC speakers or changing the mixer settings on the desktop.

Hi,
[WJ] ........

Now with the latest Windows 10 update, some changes have been made to the Privacy settings on your computer, specifically devices that act as Microphones, one of which is probably the USB codec that Elecraft uses. 
Make sure it is set to allow.

With the latest Windows 10 update earlier this week, my K3S and P3 can no longer communicate with my Windows 10 PC via the USB cables.  I?ve gone into Device Manager and right clicked on the COM12 device drive and clicked ?update driver? and that updated from a 2016 driver to a 2017 CM port driver, but neither connect the PC to my K3S or P3.  Any suggestions?  Thank you.

Message-ID: <163ad7ca612-c90-1e98@webjas-vaa192.srv.aolmail.net>


Bill:
Thanks for your input. I did EEINIT yesterday and reloaded all SW. No
change.

Today, I did EEINIT again and fooled around with the radio in its native
state, changing modes, etc.
Then reloaded saved configuration and for no particular reason, did a BSET.?
Then did a SSB +CW selection. Lo and behold, the CW behavior is what I would
expect and same as in basic CW mode.
No overshoot and power change is smooth with no jumps. On CW key press,
power starts out slightly low and builds to the set value.

I suspect there is a bug in the code somewhere. Experience says there is probably an
uninitialized variable lurking in the ALC code. **Elecraft SW developers note.**
It will be interesting to see if this good behavior sticks.

BTW, Albuquerque is my old, old stomping ground. BSEE from UNM in 1967.

Well ... define "correctly."? All simulation is an approximation of 
reality.? NEC-4 adds capabilities such as buried radial fields, and is 
more faithful for tiny antennas than NEC-2.? It treats lumped circuit 
constants pretty much the same as NEC-2, however.

Last time I checked, a US non-commercial NEC-4 license was $300, IIRC.? 
You'd need the NEC-4 EZNEC UI too.? Since the vast majority of 
environment variables impacting antenna performance in the real world 
are not part of any of the models, and we are "amateurs," I doubt you 
would see any benefit from NEC-4.

Tom,  I get prereleases for WIN 10 Pro which means I got the release you are probably discussing in this thread some time ago.  The audio codec changes in the release can be a big PITA.  I have to unplug my USB cable to the K3S in order not to have the PC speakers and the directly plugged in Stereo speakers on at the same time.  If I want to use the USB cable, then I have to use the PC speakers.  Interestingly, I can disable one set of speakers via control panel settings, but once I reboot the speaker is then re-detected.  I will eventually have too use the PC speakers, and abandon my excellent stereo speakers hooked directly to the K3S.  I prefer using the volume control on the K3S vs reaching to adjust the PC speakers or changing the mixer settings on the desktop.

73,

Hi,
[WJ] ........

Now with the latest Windows 10 update, some changes have been made to the Privacy settings on your computer, specifically devices that act as Microphones, one of which is probably the USB codec that Elecraft uses.
Make sure it is set to allow.

Subject: [Elecraft] Windows 10 Update Breaks COM Port for K3 & P3 Utilities

With the latest Windows 10 update earlier this week, my K3S and P3 can no longer communicate with my Windows 10 PC via the USB cables.  I?ve gone into Device Manager and right clicked on the COM12 device drive and clicked ?update driver? and that updated from a 2016 driver to a 2017 CM port driver, but neither connect the PC to my K3S or P3.  Any suggestions?  Thank you.

I would imagine the 1500 will be remotable just as the 500 is.  A friend of
mine remotes his 500 to the basement just as he did with his Acom 2000aand
he is investigating remoting the 1500 he just got.  As for a control box I
don't know.  Not sure if the amp faults will be visible in the vfo B area
ofthe K3.  It tells you its on-off or in standby.

the Elecraft KPA1500, perhaps an option like the K-Pod, so that the noise
source is further from the operating position?

I have been seeing this discussion about downloading the Elecraft USB 
drivers and so on.?? The latest Win10 update deleted my K3s 
USB/Soundcard setup also.?? However I only needed to plug the USB back 
into the K3s and all is good.? I did need to rename the K3s in Win Sound 
(so I know which codec is for the K3s)? I have never used the Elecraft 
drivers and everything works just fine.

Am I missing something?

Oh no... not me.? All my USB stuff is working perfectly.... even with 
the 50 lbs of gear I have hanging off the various USB buses...? <smile>? 
But you have a point. Some of these other folks may have some issues.? 
It's my business to keep system's clean, so I am massively OCD about 
doing so for my own machines.

Just bothers me that so many other folks are having issues....? I spent 
some hours today researching and putting together some tools.? I will be 
testing them and hopefully writing up a procedure for "last resort" use.
Rebuilding the USB Bus structure from the ground up is not a trivial 
task to say the least....

No idea when KPA1500 Remote will appear, Tony, but you don't need it to
operate the amp remotely. KPA1500 Utility has a very nice Operate page that
I have found quite adequate to operate my amp in the mountains from a
control site in the valley. I use Chrome Remote Desktop to view and
manipulate it. Windows Remote Desktop or Teamviewer do the same thing or
you can have a "long" serial port (cable or network device). When it
arrives, KPA1500 Remote will add client/server operation, pretty bar
graphs, and maybe more, but I'm surviving for now without it.

The functions that are lost can vary, depending on the Win10 subtype and the installed software.

With my system - Win10 pro 32-bit, two K3s with KIO3B USB cards, and VSPE port forwarding - all of the rig control functions worked as before but the two soundcard interfaces did not. Win10 reported both interfaces running OK with the latest driver already in place, and offered no option to roll back to the previous driver.

The next step would normally be to uninstall the sound interface, and then restart and allow Windows to search for and install the latest drivers; but this only installed the same driver as before.

My interim solution has been to roll back the entire Windows update, so everything now works as it did two days ago. 

For the future, I have set the update options for all so-called "feature updates"  to the more restrictive "Semi-Annual Channel" option (meaning, don't update until the update is claimed to be ready for widespread deployment in organizations) and with a further delay period of 180 days. 

However, the so-called "quality updates" that include new security features remain at their default setting of 0 days (meaning, "install immediately"). 

All of these options are accessible through Settings - Update & Security - Windows Update. For rollback of an existing update, choose Update History - Uninstall Updates. For future updates, choose Advanced Options.

None of this has involved the radio gear; it has been purely a Windows10 issue.

Message-ID: <1527669852390-0.post@n2.nabble.com>

Hi all,

ad NTCH: Is there possibility to save the NTCH setting on K3 somehow please?
it is really boring to adjusting it again and again after each turning ON
the K3. :) I though about some menu item like "NTCH save" ON/OFF in order to
choosing in between saving or not saving the NTCH permanently . even better
per band or not per band set.

ad APF: I realized that on KX3 the resolution is switched to finest (1Hz)
automatically when APF is turned ON. Is it possible to do it on K3 also? I
did not found anything in menu. It should be fine to have menu item "APF
fine dial" ON/OFF or it could be permanent functionality for APF to have 1Hz
resolution while it is activated.

Btw: APF is one of the most magic feature on K3/KX3...hi. Many DX I catch
thanks to this function.

Hi John,
For a long time I had the Acom 2000A sitting on a shelf in the basement
right below my feet in the shack. I used their remote box which worked very
well. I have a KPA500 on the same shelf using KPA500 Remote which also works
very well for controlling the amp. Once the KPA1500 Remote is available I
would think it would work as well as the KPA500 Remote program to control
the amp. I can't think of a reason to have additional hardware in the shack.
I am in the process of removing more of the manual controls to the basement.

I imagine that due to the KPA1500's size it requires a higher volume of air
than a large amplifier would. Its small size and weight make it appealing.
The Acom 2000 has a control box that is separate from the amp so you really
never hear the amp run. I am wondering it something similar can be done with
the Elecraft KPA1500, perhaps an option like the K-Pod, so that the noise
source is further from the operating position?

Thanks for the offer, Clay. But we actually did extensive thermal analysis
of both the heat sink and fans, tested many different fan types and
configurations, and did comparative noise testing of the KPA1500 vs. a
number of other amps. 

As you allude to, there's no magic bullet. Heat must be removed, with
various physical and electrical constraints to be satisfied. 

We have some pretty amazing thermal imaging devices that we use to examine
heat signatures of electrical components. These were used during R&D, which
is how we determined that two LDMOS devices were far better than one for
heat distribution. We also used it to evaluate the design of our very
large/very thick copper heat spreader. On the production line, we review all
modules for hot spots during burn-in and make sure the cooling is working
perfectly (onset temperature, air distribution around modules, etc.).

Of course supplemental cooling of various types has been used with
amplifiers in the past. I believe we have a couple of customers and staff
experimenting with this idea, and anything that emerges will be posted here.

Rick,

Was just thinking, I assume that the KPA1500 utility program is like the KPA500 Utility Program in that you can?t run in though LP Bridge. The KPA500 Remote program works fine with LP Bridge.

I will still be able to remote the KPA1500 right away to the basement till the KPA1500 Remote program comes out. I will be able to work around that limitation for now.

No idea when KPA1500 Remote will appear, Tony, but you don't need it to operate the amp remotely. KPA1500 Utility has a very nice Operate page that I have found quite adequate to operate my amp in the mountains from a control site in the valley. I use Chrome Remote Desktop to view and manipulate it. Windows Remote Desktop or Teamviewer do the same thing or you can have a "long" serial port (cable or network device). When it arrives, KPA1500 Remote will add client/server operation, pretty bar graphs, and maybe more, but I'm surviving for now without it.

If you like computer control of your station, than I agree that the remote
program is a great solution.  I still have stacks of rotator control boxes
and relay switches on my desk and I can make QSOs without a computer, which
is why I suggested something like this
https://www.arraysolutions.com/om-2500-rem for the Elecraft amp.

I'm using the K3 with the Elecraft interface cable.? I've noticed the 
the CW drive power required by mine varies considerably, both with 
temperature and SWR.? If I set the K3 output for a KPA1500 output of 
1500 W output initially, the output will drop to perhaps 1100 W when the 
temperature stabilizes at around 65 C.? (I've ruled out any change in 
antenna impedance, etc.)? A similar change occurs if the SWR goes from 
1:1 to 1.2:1 when changing frequency or switching antennas.? I haven't 
changed the ALC from the default setting.? Has anyone else noticed this?

Can you communicate with the K3 using a simple terminal server? E.g., send ?FA;? and see if you get the VFO A frequency in response.

That would demonstrate that the port and driver are working.

Subject: [Elecraft] K3 serial port fix?
Message-ID: <7653825e-b0b0-aa20-ddbb-d081656cd706@gmail.com>

How difficult is it to replace (realize I am challenged in the delicate 
touch department) whatever board in the K3 does the serial 
port/interface to the radio?

Is it likely a go back to the factory thing or an easy desktop job for a 
klutz (me)?

The reason I ask this is my K3 suddenly seems to respond to input from 
DXLab Commander, but not send out changes like VFO, band switching, 
etc.? I suspect its the K3. and will confirm tomorrow by using a 
different PC to talk to it...

Thoughts?

Thanks & 73 de Dave, W5SV

I didn't realise that Win10 Home lacked those update controls, so my

Win10 64K Pro is running on the machine I'm using for my engineering 
work, tech writing, and email, and I've not been able to tame its 
updating. Can you please help me find these settings? I'm losing stuff 
when Win10 asks if I want to update, doesn't get a reply, so does it. 
AAARGH!

OK.... I think these are ALL the links needed to get all the stuff I used...

Essentially, you want to use USB Oblivion, Ghostbuster, USB View, an 
Enviroment Variable change to show unconnected devices, et al to make 
visible what you need to see AND to allow you to CLEARLY identify which 
devices need to be uninstalled. Ghostbuster has the additional function 
of IDing other stuff too.? You want to be VERY sure you aren't deleting 
something you don't want to delete or you CAN hose the installation of 
the OS entirely....? There are a number of things I don't touch...? Use 
Google search and read if you aren't sure.? The VID/PID listing will 
help you ID devices with crappy descriptions bu IDing the manufacturer 
(Vendor ID/VID) and product (PID).

NOTE: Connect ALL critical USB components before starting EXCEPT the 
devices that aren't working properly.? THEN, don't uninstall any 
connected devices.? IF you have multiple configs on different ports for 
the SMAE device, THIS should help ID which is where and which to 
delete.? Delete ALL instances of NON-working devices.... HOPEFULLY, 
doing so will allow a FRESH install of the non-working device that will 
function properly.

http://www.thewindowsclub.com/usboblivion-remove-usb-traces-windows

http://www.thewindowsclub.com/a-ghostbuster-for-your-windows-7

http://www.thewindowsclub.com/show-non-present-devices-windows

http://www.linux-usb.org/usb.ids

https://docs.microsoft.com/en-us/sysinternals/downloads/pstools

https://wvd-vegt.bitbucket.io/

https://docs.microsoft.com/en-us/windows-hardware/drivers/debugger/usbview

You'll need to become familiar with how it all works....? Win 10 DEVICE 
MANAGER is your friend.? The "Details" tab on each device entry will 
give you a way to cross check each device in the tools I listed above to 
VERIFY if you want to uninstall a device.? While the tools have varying 
ability to do this automated in and in mass fashion, I ONLY used Device 
Manager to do the uninstalls.? One of the articles shows how to set an 
Environment Variable in "Advanced System Settings--->Environment 
Variables that allows DEVICE MANAGER to display disconnected devices.? 
THEN, in Device Manager you set it to "SHow Hidden Devices".? NOW, it 
will show everything.? Then use primarily Ghostbuster (download at Swiss 
Tools....) (use the installable version, the portable version isn't as 
feature filled.) to identify candidates...? cross check with the other 
tools AND the Details tab on Device Manager... Then, decide if you want 
to uninstall, and then uninstall... ONE at a time!!!

In general....? don't uninstall any "hubs" even if they aren't 
connected.? There will be an entry probably for every flash drive or 
card reader EVER connected.? Certain devices if they were plugged into 
multiple ports will have multiple entries.
USBVIEW from Microsoft via the SDK Tools, will show you a GREAT 
hierarchical layout of the ENTIRE USB tree established from last OS 
install.

Hope this helps a little...? I had 237 entries on Ghostbuster of all 
type devices....? 82 of them were NOT connected.? I ended up deleting 
some 70+ devices...

As a side note....? my computer sped up quite a bit.... I deleted at 
least ONE thing I probably shouldn't have and it caused my USB Audio 
Codec entries to be re-enumerated and dumped the title and custom icon 
on it.... It happened to be one of my VNWA USB Codecs and VNWA chose the 
wrong two on next startup.... Chose two from my Mackie Pre-Amp USB 
audion interface....? Took me about 20 minutes to figure it out and 
re-set it up.... but the ones it created WERE still there.


PS - Have NO IDEA if this cleanup will fix anything for those of y'all 
who are having issues... My system was working perfectly before and now.

BUT, I suspect that uninstalling the disconnected entries of NON-working 
USB devices will pave the way for a working FRESH install.

Going on 2 all-nighters in a row... I am going to sleep now.

ONE way is to go to:

Settings --> Update and Security -->? Windows Update (default)

Click on "Active Hours" and set those times how you want them. Windows 
will not auto-restart during those times.

Additionally/Alternatively...

Click on "Advanced Options" from the same place and turn ON the switch 
for "Pause Updates".? This will pause updates for UP TO 35 days.? The 
text there will tell you the exact date a pause will cease IF you don't 
turn it off sooner.

Also, turn on "We'll show a reminder..." switch on Advanced Settings to 
get additional warnings PRIOR to auto-download and restarts.

You could ALSO make sure "Semi Annual" is selected rather than 
"Semi-Annual (Targeted)".? THIS will slow the major updates down some so 
that maybe the big stuff will be fixed before you are force fed the 
major version updates.
++++++++++++++++++++++++++++

IF you want to stop updates altogether and ONLY manually get them when 
you want them (not recommended for the NON-OCD or forgetful among us), 
set your network connection to "Metered".

Here is an article that outlines how to do it on either a wireless or 
and wired connection, AND Windows stores sepearte info for EACH 
network... So if you set your home wireless or wired connection to 
metered, you aren't supposed to get NAY updates UNLESS you do a MANUAL 
"get".

https://www.howtogeek.com/224471/how-to-prevent-windows-10-from-automatically-downloading-updates/

+++++++++++++++++++++++++++

BUT, IF you JUST want to stop the auto-reboots....? Then set Active 
Hours for a 23 hour period... leaving an hour during known sleep or 
non-use times when the system can reboot to finish installs.

Hope this helps...

Jim,

Apologies, I am about to go away from the office/shack computers for
a few days, but my posting on Wednesday already tells everything I
know. The route to the settings is in the penultimate paragraph.

Can you safely increase the drive to get it back to 1500W?

Another question: Is the drive requirement (amp 
gain) pretty flat from band to band?

Yes, it does sound like a solid-state thing.  Not enough negative feedback?  It may be a reason NOT to run the fans continuously: Once it reaches 60 C, the fan control keeps the temperature fairly stable.

Yes, turning the drive up a bit restores the output to 1500 W.

I haven't recorded it, but drive seems fairly flat band to band. (The K3, of course, saves the drive levels for each band.)

I have experienced power level changes with s/n 45 since day one.  I had envisioned setting the K3s config to ?power per band?, adjusting the power level to just below 1500 watts on each band, and then being able to switch bands and magically find that the power level is still sitting exactly where I left it ?.. but no deal ? typically, after I return to a band where the level had previously been right at 1500 watts, the first couple transmissions (CW) will often jump up to 1600-1700 watts ?. It drops a little after the first couple dits, but I almost always have to readjust and crank down the drive power ....  so I now crank down the drive and readjust every time I change bands ?.. not what I had hoped for ?  and yes,  I also see small decreases in power level as the temperature increases as others have noted.

My KPA500 also has slightly inconsistent output. If I recall output drops
a little after the first few seconds of key down. Perhaps it is normal for
solid state amps as I have never noticed this with a tube amp. This may be
more of a concern with a legal limit amp if you want to keep it as close
to 1500 watts without going over.

I've seen some gain drift with temperature, too. I've wondered if there
might be a way to feed back drive power change requests to a K3, or other
radio with adequate command capabilities, to maintain a target output power
(say, 1500w) as the amp warms and cools. This should be done slowly - on
the order of seconds, not milliseconds like ALC. KPA1500 Utility knows its
output power and could be programmed to generate the requests. I don't know
how to get commands into a K3 that has its serial port connected to a
logging program. There are some port-sharing tools out there that might
work, but I'm not familiar with them. In any case, it would require some
engineering at Elecraft. In the meantime, I keep an eye on output and tweak
the drive manually to stay both powerful and legal.

The junk changes while transmitting (FT8). Pretty sure it?s RF.

Message-ID: <87F2E543-9355-4DBD-BBED-A5D6F0859694@law.du.edu>

 This may be an instance of a much larger problem, one that has been discussed with regard to automobiles and light machinery among other environments of computer-type programming.  It is, I suggest, a problem as much jurisprudential as electronic.

When I buy a computer and an operating system, who owns it?  Does it belong to he who bought and paid for it, or does it continue to belong to the company that produced it?  Windows is not alone in this.  Mac OS has its own version of forcing unrequested and often unauthorized updates, as is Samsung / Android or whoever makes those systems.  Updates are installed at the producer's election, and as often as not in my experience with all three systems they disable or scramble the functions of some application I had been relying on.

I don't recall granting permission to any of the operating system producers to enter my computer unacknowledged and change it, however benevolent their purpose may be.  It is not a stretch in my mind to say that this is not much different from an automobile maker keeping the keys to the car I bought, finding it in my garage and entering it some night, and changing the color of the upholstery without my knowledge or consent.  Absurd, right?  From a macro-legal point of view, it's not a bad analogy.

And then the complaints are met with silence.  If a fix is offered, the user has to go hunting for it.  No-one has ever told me that they patched something they fouled up.  Elecraft itself it very different.  Updates are announced; they are optional; the changes they make are described; and when a bug appears, the discussion even by the company owners is prompt and responsive.  My ire is directed rather at the Big Three of the nether world.

Users of the world unite!!

    Win10 64K Pro is running on the machine I'm using for my engineering

    updating. Can you please help me find these settings? I'm losing stuff

There is a difference between security packages and bug fixes and upgrades.

Security patches are important in our highly-networked world.

When an "upgrade" affects functionality, that is unacceptable.

The typical Windows 10 upgrade is twice the size of the typical Linux 
distribution.

Android at least does this mostly-right.  A major upgrade requires 
permission, security patches don't.  This isn't always true of 
applications.

I agree with Rick:  A way to slowly adjust the drive power automatically to maintain constant peak output would solve the problem. I'd think the KPA1500 firmware could do this with the K3 via the accessory cable. Probably the K3 should revert to its original output when the KPA1500 is cold, or power would initially overshoot.  Better yet if the amp could remember drive power for each band as a function of temperature. 

While it's annoying to have to keep fiddling with the power control, I can understand that there are higher priorities now.

Scott K9MA

Are you sure that it is not the K3(s) itself that has unstable output power.  I see this occur on my KPA500 and it is not getting hot.

Here I am at work, my KX3 arrived, and I opened the box.
I had ordered the assembled radio with the NiCad/RTC option.

I presume I can wait till I get home.. But,
Quick question: The radio does not turn on.  Does it come with the battery
fully discharged, disconnected or what?  I would have thought there would
be some note about that.

Gerry, the option does not come with cells.  You will have to install 8 NiMh cells into the pack.  I use the highly recommended Sanyo Eneloops in mine.

First, it designed to use NiMH batteries, not NiCads.  Second, batteries are not included.

I?d suggest Panasonic Eneloop Pros, but others have different preferences.  Whatever.

And if you can?t find Eneloops locally and have to order batteries on line, and don?t want to wait, just open it up and put in 8 standard AA cells.  It will work fine.  Just don?t turn on the charger :-)

You can also power the KX3 from an external 9-15 V battery pack (e.g. our KXBT2 & its fast charger) or a power supply. One popular supply:

When I try to charge the battery I get Bat err message and charging is
terminated. I have reloaded s/ware etc but no change.
Any ideas ?
Thanks

Message-ID: <5a3ca781-3b24-f1b4-34ab-dd5be4e6e154@gmx.net>

Hi all,
at the WinTest-reflector people asked why the K3 does not appear 
"smooth" in the band map as another vendor's TRX.
I made some tests and found out the following, see below.
Now my question: will the new USB-Interface change that timing behavior?

tnx, 73, Gernot DF5RF

Be careful opening the KX-3.  There is a ribbon cable in there that remains
attached when you open the unit.

Absolutely. I have never seen such fluctuations of either output or grid current with my other amplifiers.

Bob,

Read the BAT ERR description on page 4 of the KXBC3 manual.

You may have to remove the batteries and check the terminal voltage of 
each one with your DMM to determine if you have a bad one, or if all are 
possibly fully charged.

Reloading software will not make any difference, but likely will not 
hurt anything either.

Don W3FPR

Gernot,

The USB interface will not change anything unless your computer changes 
something at its end.

Realize that the K3S or K3 with the USB interface still runs internally 
with RS-232.  The USB interface simply moves the FTDI adapter chip 
inside the K3/K3S.  You still have to identify the COM port that is 
assigned by the computer to your software applications.

Oh yes, a soundcard chip is also added.

Don,
ok, thank you. That clarifies the issue. Would be nice to hear from the 
Elecrafters if there are any firmware changes possible to improve the 
IF-message timing.
If not: I already had the idea to implement a frequency counter which 
measures the VFO's frequency, connects to the RS-232 output and combines 
the two into a super-responsive frequency status message generator :-)
Anybody interested? Then maybe I'll give it a try.

I will also vouch for the PAE KX33 power supply, it is ideal for the 
KX2, KX3 or the K2/10.

If you are running a KX3 with a PX3, Pro Audio Engineering has a "Y" 
cable that powers both from the same supply.

I'd swap out the batteries and then go through the procedure that Don
recommends.

Dumb question; they are all NiMH, right?  Hopefully Eneloop or a similar
marque?

Make sure the NiMH cells are "precharged" types.  They're 
low-self-discharge.

Standard NiMH will run down by themselves rather quickly.

Message-ID: <91520D31-8286-4DBB-88FF-194E40B1D1D6@elecraft.com>

Hi all,

As we suspected, the SWR bar graph fluctuations observed by some KPA1500 owners were caused by an algorithmic anomaly in the firmware. This has been fixed. A few of our field testers will be checking out the new firmware for a couple of days before we do a wider release.

Thanks for your patience.

What is the average cost of repair? This is for radio problems/failures not
for operator damage.

Gerald,

The cost of repair varies depending on the problem.  Most repairs can be 
accomplished within 2 hours labor at $99.00 per hour.
