Here's my take on filters.

I intended to send it to the reflector but realise that I sent it direct to
K9MA only.

I bought 200Hz filters for both main and sub receiver when I did a major
upgrade of my K3. I already had a 400Hz in the main receiver.

I would say from personal experience that the 200Hz filter is a very
worthwhile addition and makes a difference when the going gets tough.

The "marketing name" on the <Inrad> filters is effectively the -1dB
bandwidth.  The name is derived from their original use in Yaesu rigs
and Yaesu's marketing where there were two filters in cascade and
represents the final effective bandwidth of the cascaded pair.  Plot
the cascaded bandwidth of the Inrad #701/#703 pair (400 Hz), #708/#704
pair (250 Hz) or the #711/#714 pair (1800 Hz) and see how that works.

When one has only the first IF filter, the "cascade" is provided by
the 2nd IF DSP.  In the K3/K3S what does the "WIDTH" display actually
show - the -0dB, -1dB, or -3dB point of the 2nd IF response?  Then,
how does that match with the first IF filter and what is the composite
response.

Dear Elecraft friends, 

My K3 #6884 is exhibiting a transmission problem first identified when I couldn?t check in to one of my favorite 75 m nets the other morning on SSB.   

The behavior is that it is transmitting noise.   When I increase MON volume I can hear it quite clearly.    This happens on both of two microphones, MH3 and Yamaha CM500.   It happens less frequently on digital modes (using line in) and happens for a moment at the beginning of a transmission and then goes away. 

Here is a link to the audio recording I made of it using my iPhone (m4a file type).  I was not transmitting at the time as I was in TEST mode. 
https://www.dropbox.com/s/lfxo79hhahsj1uh/K9QJS-K3-TX-Monitor-Test.m4a?dl=0 <https://www.dropbox.com/s/lfxo79hhahsj1uh/K9QJS-K3-TX-Monitor-Test.m4a?dl=0>     

I have done a reset and reloaded all configuration parameters.   I am running 5.60 firmware on it and have reloaded the firmware to the K3.  

Thoughts? 

Thanks in advance and happy New Year.

Message-ID: <038301d38335$52c47b30$f84d7190$@cox.net>

Happy New Year to all!

 

I have a K3 with the internal K144XV 2m module.  This works FB but both TX
and RX are on the same antenna port.  In a configuration I am thinking of
using, there would be separate RX and TX lines.  

 

With my main 2m EME station which uses a second K3 and a 10m to 2m
transverter, I have it configured with 28 MHz TX out on ANT2 to the
transverter input port and 28 MHz RX in on the RX ANT IN port with the front
panel .  This works FB.  I have the XVTR PWR menu setting such that it
outputs 3 watts which is directed to ANT2 rather than the XVTR OUT port.
Even though I am using a transverter, I am not using the back panel XVTR IN
and OUT ports.

 

When I attach the output of a 144 MHz to 28 MHz downconverter RX line to the
RX ANT IN port and enable  RX ANT function on the front panel, the K3 with
internal K144 XV 2m module does not give me the desired results.  

 

I hope I have made this clear.  It seems that this should work with the
internal module since it works as I want with an external transverter.

 

Ideas or suggestions?

 

Jim

I believe the internal xvrtr routes the rcv antenna connection 
through a header on the board and in normal operation, that is 
jumpered. I would think you can remove the jumper and use the header 
to make your receive connection

	Pacific Time
Message-ID: <CAOmNKGJvQEnLsiim+4x+bngs_6g+7v6Od61No-DoZnquwVAH2g@mail.gmail.com>

Regular price $139 ea., New Year special price, only $129 ea. if you order
by the end of today.

For photos, see https://bit.ly/Y-BOX .

This special is for the *original* Y-BOX (only), which requires a M/F
Elecraft KPAK3AUX cable (P/N E850463, not supplied) to connect a KAT500,
KPA500, or KPA1500.

I've also started a waiting list for the *new* Y-BOX, announced below  It
has a new Key Line Interrupt connection option just for SteppIR owners, and
a new connection option to power on your KPA500 or KPA1500 via a K3 macro.
This new version can be connected directly to a KAT500, KPA500, or KPA1500
using any standard M/F cable with all 15 pins wired (but not a VGA cable);
there's no need for the custom KPAK3AUX cable (though it will work fine
too, but you won't be able to power on the KPA500 or KPA1500 with a macro
if using that cable).

Direct link to Order Form / Waiting List:  https://goo.gl/forms/
Guu6OC6NinTlasY93

Please indicate in the comments which version you want:  original or new.
Price of new version will be $139 ea. if there is sufficient demand,
otherwise $149 ea. due to board costs.  The new model will be be ready to
ship before February 1st, 2018.

Amphenol M/M cables and M/F extension cables with all 15 pins wired are
also available for purchase with your order of a Y-BOX.  Cables are not
sold separately unless you previously purchased a Y-BOX from me.

Happy New Year!

So I guess you're saying that there is not much difference, only 55Hz, so
maybe it is not worth the cost of having both. My K3S's are programmed to
switch these roofing filters in closer to their actual passband. The cost of
the 250Hz filter is a small percentage of the transceiver cost so I do not
mind having this option.  I see it being far more useful than the 1.0Khz
filter.  WD8Z said that he ordered the 400Hz by mistake and my initial
comment was that it is a fantastic CW/RTTY filter. I have two in each of my
K3S's.

The actual passband of these two filters is more important than the
marketing name.  The "400 Hz" filter is about 435 Hz wide at the -6dB
points.  The "250 Hz" filter is about 380 Hz wide.  Look at the graphs on
the Elecraft website.

400Hz is definitely my favorite CW and RTTY filter. I also use the 250Hz
roofing filter (switched in at 350Hz) when the QRM gets bad, what document
shows that this offers little improvement?

use the 400 Hz ones.

A quick look at the Elecraft filter response plots for the KFL3A-250 and 
KFL3A-400 shows these bandwidths:

dB????? -250???? -400

-6?????? 400????? 420
-20????? 480????? 530
-40????? 600????? 700
-60????? 780????? 920


So, the narrow filter won't make much difference close in, but may 
provide more rejection more than 200 Hz from the center frequency.? 
(Assuming it hasn't drifted too far.)? Another way to look at it is that 
the narrow filter has about 10 dB more rejection beyond +/-200 Hz.? 
This, of course, adds to the DSP rejection, and may prevent overloading 
of the DSP by a strong adjacent signal.? How often this makes any 
difference is hard to say.

I can say that I can't recall ever switching to the narrow filter to 
reduce QRM from a signal more than about 400 Hz away.? I frequently do, 
however, for those less than 200 Hz away, in which case the extra 
rejection must come almost entirely from the DSP.

Subject: [Elecraft] [K2] Kit Building Tips / Lessons Learned
Message-ID: <1514838122654-0.post@n2.nabble.com>

First, let me start out by thanking the fine people at Elecraft for their
exceptional quality and expert service. I especially want to thank Gary
(AB7MY0) for his advice and patience in responding to my questions. I wish
the folks at Elecraft a very Happy New Year, and many continued years of
success!

Background...I bought a K2/10 at the Mike & Key swap meet last year. I used
it both QRP from parks and from my sailboat, and also took it and an RM
Italy HLA305V to operate in Vietnam last year. It had been many decades
since building a Heath kit with my father, so I decided to take advantage of
the Black Friday sale and order a k2/100 with all the trimmings (except
internal battery and atu). Now my K2/100 & KAT-100 are on the air, so I
thought I would share some things I learned along the way for others who are
about to embark on their K2 kits.

1. Get an ESD mat and wrist strap. They are not expensive and offer piece of
mind. Also a PanaVise to hold the printed circuit boards was nice set of
'extra hands.'

2. Use a good pair of flush cutters; not side cutters or dykes for clipping
leads. Esp. important on control board.

3. I used a Xytronic temp controlled soldering station with 3 different
tips: 1/16" for tight areas, 1/32" semi-chisel was most frequently used to
reduce dwell time, and 3/16" chisel for the heavy binocular toroid's. Adjust
heat setting accordingly to reduce dwell time.

4. A good, comfortable of head band magnifier is indispensable; esp. for
checking solder connections.

5. Get a small desk fan to blow flux fumes away from your face; especially
when prepping & tinning the toriods and transformer leads. I picked up the
O2Cool fan for $20 bucks at Staples. Runs off batteries, USB, or 5VDC pwr
supply.

6. Elecraft suggests doing a complete kit inventory before beginning. This
not only ensures you have all the parts, but it is also a great way to
catalog the parts to speed up the building process. Fortunately most
resistors were laid out in strips according to installment instructions.
Capacitors and other parts I laid out on paper and taped them down with 1/8"
masking tape in groups and labeled them by value, description number, and
schematic ref. number. In all honesty, I did not do with basic K2
transceiver kit. I spent many hours picking through the capacitors trying to
identify the right ones. For the filter kit, noise blanker, and amp...I use
this method and felt the day invested in separating and identifying
components was a good investment of time and sanity. BTW...Gary also sent me
this PDF for help identifying capacitors
(http://grathio.com/assets/capacitor_tags.pdf)

7. There are a couple of components (eg. C46) installed by soldering the
lead to the pad with a blob of solder. Read head to identify all components
installed this way. Instead of flush cutting the leads of the components
(e.g. Q8 and R21 in the case of C46), cut those leads to about 1/8" to
provide a better and cleaner looking connection, and cut as close as
possible afterwards.

8. Inspect each solder connection after clipping the lead, or after each
component. I missed soldering one connection on a resistor pack which led to
some bizarre behavior during initial tests. It freaked me out to have such a
simple mistake so early on in the project. I slowed down, and diligently
verified each solder connection after that for my own piece of mind.

8. During the VCO alignment procedure I could not get the max voltage above
4 vdc. Once again Gary came to the rescue and suggested squeezing the red
windings of T5 a bit. That did the trick! I wish that were annotated in the
manual. 

9. Take your time. I took a 30 break at least every 2 hours, and didn't
spend more than 8 hours per day on the kit, not including reading ahead in
the manual or researching various web sites for BFO alignment tips and
things like that. While I wanted to get my K2 on the air...it was much more
important to build the kit correctly (esp. after that resistor pack incident
early on). All in all, it took about 3 weeks given a few days off for the
holidays.

10. Have an independent, well-lit workspace. I setup a collapsible 24"x48"
table in the corner of my shack. It was nice not to have to put things away
and restart, but it was also important to keep things nice and tidy at the
end of the day.

There are probably some other things I am forgetting, but this was a fun
project. I took my time,  learned a lot, and I am now on the air. The
K2/100, KAT100, and W2 will now be my primary rig when operating from
Vietnam, is also likely to replace my Icom M710 aboard my sailboat, and a
second radio in the shack.

Hope to catch you on the air.

 ?KFL3C-200??? 200 Hz

Look at that one instead of the 250hz if your going to put a narrow one in.
I have both and the 200 is more xtals and is better.

All, 

In the FWIW department, I appear to have resolved my problem. 

The problem appears to be a poorly seated Line In connector.   Removed Line In connector and problem went away.  (Menu MIC+LIN = ON).   Reseated connector and problem still not present.   As a general practice, I?ll use MIC+LIN = OFF in any event.

Dear Elecraft friends, 

My K3 #6884 is exhibiting a transmission problem first identified when I couldn?t check in to one of my favorite 75 m nets the other morning on SSB.   

The behavior is that it is transmitting noise.   When I increase MON volume I can hear it quite clearly.    This happens on both of two microphones, MH3 and Yamaha CM500.   It happens less frequently on digital modes (using line in) and happens for a moment at the beginning of a transmission and then goes away. 

Here is a link to the audio recording I made of it using my iPhone (m4a file type).  I was not transmitting at the time as I was in TEST mode. 
https://www.dropbox.com/s/lfxo79hhahsj1uh/K9QJS-K3-TX-Monitor-Test.m4a?dl=0 <https://www.dropbox.com/s/lfxo79hhahsj1uh/K9QJS-K3-TX-Monitor-Test.m4a?dl=0>     

I have done a reset and reloaded all configuration parameters.   I am running 5.60 firmware on it and have reloaded the firmware to the K3.  

Thoughts? 

Thanks in advance and happy New Year.

Some time ago,? bought some when they first came out,? swapped

May have been in 2016 not sure.

Hi all,

the interesting think is to check the first -30dB attenuation skirt first.
(After about -30dB down from the peak of the crystal filter response curve
the DSP handles the remaining signal rejection for very strong signals that
are inside the filter response curve, effectively sharpening the remaining
filter response and limiting the b/w to that point) 

Just the 2c...

Happy and healthy New Year 2018 to all over there!

Dear John,
I found that the Powerwerx that Elecraft resells (see:?Elecraft? Hands-On Ham Radio?) resells meets your requirements. It is also available from Powerwerx (see:?Power Supplies | Powerwerx). I switched to it from my Astron power supply. I have detected no RF hash on my Elecraft products or on my IC 7300.

The strongest hash moves up and down 8the 80 meter band..  But my main objection is that it shuts down the KX3 at turn-on.  I use it with the PowerWerx PG40S and a 12 volt battery.  Whenever I forget to turn on the SS30 first, I have to repower the KX3 and then use the menu to switch the power amp back on.

The KX3 display briefly displays an overvoltage message.

Subject: [Elecraft] PROGRESSIVE TUNING RATE
Message-ID: <CA+iQqthnw_Lvq_1NP8DR6T5_9Lt1sKBU60DyAcCRCQAeNeWeTA@mail.gmail.com>

I was watching a video last night that Bob Nagy, AB5N did on the Icom 7610.
In the video Bob showed a feature called "Progressive Tuning Rate" that
varies the tuning rate based on the speed of the tuning knob.  Please see
https://www.youtube.com/watch?v=elW42Nkiu0U at about 5 minutes into the
video for more info.

I'm wondering if there could be a firmware enhancement that would allow a
K3(s) (or a KX3 for that matter) to do this?

Thanks

My 20+ year old Icom 775 DSP does the same thing.

Message-ID: <1503729439.1277970.1514901644858.JavaMail.open-xchange@mtlgui02>

My SS30DV has worked flawlessly for about 6 years on a variety of rigs and other
uses.
Contrary to the lack of such info, the actual voltage IS ADJUSTABLE with a small
potentiometer inside the unit.
However, there is a flaw in the unit. I use it at a condo on a beach of the
Atlantic Ocean in Cocoa Beach, Florida in the winters. The area around the rear
entrance for the air intake for the fan is totally rusted and the paint around
the vent is completely gone. There is, obviously, salt in the air, even though I
used it only inside, on the floor near the sliding glass door to the balcony.
While it is still working OK, I suspect that there is also corrosion inside the
unit, but hope that it doesn't cause a failure. A better antirust coating and/or
better paint job should be used. My K3 shows no corrosion nor rusting of any
parts, including inside. I did opt for the Stainless Steel Case screws in
construction.

I have the Astron SS30M which I find to be electrically quiet, excellent 
regulation.? The fan does cycle on and off from time to time and that is 
noticeable.??? I power 3 radios, not at the same time, from this 
supply.?? Originally it has the Pos and Neg connections where you insert 
the wire and tighten the screw on the side.?? I too 2 brass, 10-32 
screws, 1 1/2" long, cut off the heads, filed a small flat spot on the 
side at one end, inserted one of these in the connectors and tighten the 
screws.? Now I have two studs to which I can place several ring 
terminals and secure with a wing nut.???? From these I have the power 
for 3 radios, SWR/Pwr meter, antenna tuner all attached.?? I did add a 
dedicated ground terminal to the rear of the supply.?? This is the 
common point for all of the station equipment ground bonding.

Jim,

The K144XV is natively a single antenna port transceiver.
But if you need separate TX and RX antenna connections for your 
transverter, note that there is a jumper setting that can apply +5V on 
the output coax during transmit - see page 21 of the K144XV instructions.
You should be able to use that voltage along with a small relay to 
change the K144XV antenna between your transverter's 144MHz TX and RX 
antenna connections.

73,
Don W3FPR

I had a similar bad weather situation with my VHF operating in VHF 
contests. The 144 MHz position was next to the door that went outside, 
and the shack was alone on a rocky hilltop. It was 26 miles from the 
ocean, so very little salt air, but the door was usually open and fog 
and humidity was a recurring event. I always noticed that the 144 laptop 
would crap out quite often. Any other computer up there would work OK, 
but that unit near the open door would always fail. (usually a bad 
keyboard or bad hard drive.) I also had rusty screws on the K3 which was 
also close to that open door.

Hi,

Icom has had that for a long time even for their low end rigs such as the
IC-718. This has been suggested here a while ago for Elecraft to consider.
As far as I know the idea was rejected. I liked it on my Icom rigs, but some
people truly hate it. Nowadays many people, including myself, use
panadapters that allow point and click QSY. That can bring you straight
across a band with a couple of mouse  clicks.

Happy New Year to all!

I have a K3 with the internal K144XV 2m module.  This works FB but both TX
and RX are on the same antenna port.  In a configuration I am thinking of
using, there would be separate RX and TX lines.  

With my main 2m EME station which uses a second K3 and a 10m to 2m
transverter, I have it configured with 28 MHz TX out on ANT2 to the
transverter input port and 28 MHz RX in on the RX ANT IN port with the front
panel .  This works FB.  I have the XVTR PWR menu setting such that it
outputs 3 watts which is directed to ANT2 rather than the XVTR OUT port.
Even though I am using a transverter, I am not using the back panel XVTR IN
and OUT ports.


When I attach the output of a 144 MHz to 28 MHz downconverter RX line to the
RX ANT IN port and enable  RX ANT function on the front panel, the K3 with
internal K144 XV 2m module does not give me the desired results.  

Ideas or suggestions?

I believe the internal xvrtr routes the rcv antenna connection 
through a header on the board and in normal operation, that is 
jumpered. I would think you can remove the jumper and use the header 
to make your receive connection

My FT-847 from 20+ years ago had it, Yaesu called it the "Jog Ring" or 
something like that. I found it to be annoying at best, and frustrating 
most of the time.? I think this has come up here in years past with no

will be optional.

My Lowe HF-150 receiver (1991) has it.

By now, I think we?ve established that the feature is not protected by a patent, since it is implemented in so many radios.

I too am going to work remote and have a need to get/set the LINE IN level
programmatically.  The November 2017 programmers reference still contains no
commands for LINE IN.

Given how it works on the front panel I was expecting the MG (mic gain)
command to return the LINE IN level when in DATA A mode just as the MIC knob
does in DATA A mode. Alas, that's not how the MG command works - it always
returns mic gain without regard to mode.

Is there a way to get/set LINE IN I've overlooked?

Thanks,

Thanks everyone for the responses.
Also found a post from a few years back that talked about this too (from Don I think referencing Wayne). Puts my mind to rest. I was worried that I may have messed up my assembly, but it turns out that this thing is so sensitive that it can hear/interfere with itself!
Kind of like the ringing in my ears.

Do you by chance have ATTN on the KX3 engaged? If so, turn it off, and turn on the PREamp on the KX3. That should eliminate the peaks in the PX3 that you are seeing.

Ok - finished doing the Opposite Sideband Nulling. (Also made sure the plugs were seated properly.)

The signals still show on the PX3 display, but not as strongly.
I?ve checked it on all bands and each band has at least one of these signals, some have up to six showing (with span set to 50.)
The placement of the signals is not the the same from band to band, however no signal is less than 12khz from the center frequency. Again, tuning up or down within the band does not affect the displayed signal.

Any ideas?

I actually thought all radios had this feature. When I first got my KX2, i kept turning the knob faster and faster looking to see if it would kick in, and was kind of disappointed when it didn?t. So I would like to see it added to the KX2 and KX3.

About the only thing I like about using my Drake R4C over my K3S is that I can cover a lot of band with a couple of twists of the Drake's tuning knob, at 25KHz per rotation. However, it's tough to clarify SSB at that rate, though it's actually not too fast for CW for me.

I'd love to see the K3S have a progressive tuning rate, with adjustable parameters - acceleration and max rate.  Acceleration would set how fast the progressive tuning rate advances; max rate would set the absolute max tuning rate.

If it ends up working anything like that 'feature' on the Yaesu FT-847, 
it will certainly not please me - and I will want a way to turn it off.

I find nothing wrong with the tuning rate selection on the K3 or KX3/KX2 
using the RATE button(s).  In addition, you can set the VFO OFS so that 
the VFO B knob can be used for rapid QSY.
Those provide me with controlled QSY operations instead of "somewhere 
WAAY up (or down) the band" that I have experienced with other radios 
having that feature.

Set the parameters and use the rate button,? push go fast, push go slow,
you an set how fast or slow you wish to go.

If you desire a small lightweight power supply, the Powerwerx SS-30DV should
be fine. There are some reports of noise on the EHAM reviews but also many 5
star ratings. I use the Powerwerx unit for contest expeditions and I have
not noticed any RFI or other issues.

Message-ID: <CAHmQzTkADwKnnD9fsvApNELmdZesQaTZ7+iZV69D=k9G5-vE+w@mail.gmail.com>

Seems like some requests for ballistic tuning have returned to the
reflector after a long quiet spell.  Ballistic tuning is what the JA radios
do when you spin their VFO knob faster; it senses the rotation dynamic and
increments the tuning differently until the rotation speed goes 'back' to a
slower rate.

As a response to the original ballistic tuning feature request made shortly
after the K3 was introduced, a firmware update implemented an option where,
if enabled, the offset encoder (lower right-corner knob) would act as a 1
kHz rate auxiliary 'fast' VFO.

Just like the band-stacking register feature, if one comes 'from' a rig
that had that feature ... to one that doesn't, it's a change that takes a
bit of adjusting to get used to.  Some love having it; others decidedly do
NOT.  Even harder when you have two rigs and one has it and the other
doesn't!

(The TenTec Omni VI had band-stacking registers but not ballistic tuning.
That was weird.)

I know that the K3 cannot ever have *real* band stacking registers, even
with the K-Pod.  There's no dedicated per-band button on the radio so,
that's that.  Some have tried to tell me to use other buttons in a
convoluted two-step process.  Ergonomically, that's even worse, to me, than
not having the feature to begin with.  I always wanted the KPA500 per-band
buttons to be able to enable a band stacking register function on the rig
itself, but that doesn't seem to be possible either.  Alas.

With the advent of the new synthesizers and the better-weighted knob, I do
think an optional ballistic tuning feature would be a welcome addition to
my K3.  I'd turn that feature on instead of the offset-knob coarse VFO, or
maybe have BOTH enabled.  Others would prefer it be left off.

... say ... while I am on the stump, what happened to the other 'board
level' modification for the K3 that was talked about several years ago?  I
added the synthesizers and other updates to my K3.  Was waiting for the
"big board" to become available.

I think it would be nice for a future firmware update to add a progressive tuning rate.  I can imagine the simplest added root menu item: VFO PRG [Disable (or OFF)/Enable] (rather than complexifying the existing VFO CRS submenu).  Adding more options would be possible for a VFO PRG menu item, e.g.: [OFF/x5/x10/x20] (where x=equals the currently set Fine or Coarse tuning rate for the current mode).  A non-user-accessible sensing threshold would probably be acceptable.  {One can imagine a VFO PTH; but such an item might tip the complex-o-meter needle past the ?needlessly complex? mark} ;)

More than 7 chars in the VFO B alphanumeric display would be helpful, although it?s too late to change that.  This will have to wait for the introduction of the high-res colour raster displays of the KX4 and K4s.  {I?m making this up}

When I get home after being in the hospital and rehab mostly since mid-August, I need to thin the herd-and not only Elecraft items.

I checked eBay for sales/auctions for these three transceivers, and came up empty.  Maybe it?s the time of year.  Maybe it?s the commissions?

Of course, I would first offer them to members of this list and QRP-L, rather than making eBay and PayPal any richer.

Hi John,
I would check the s/w versions of each of the rigs and kpods to make 
sure they are all the same.
try exchanging one kpod with the other and see if the led on stays with 
the rig or the kpod.

My guess is the sw in one of the devices is lower than the other device.

Linas,

Yes the PTT cable is necessary.  During tuning the power is reduced, and 
the way that is accomplished is for the KAT100 to open the PTT line to 
the amp.
If you have an amp that only takes a small amount of power to drive it, 
your exciter may not have enough power to do a proper TUNE - that takes 
20 watts for reliable results.

I'd use the "Car Talk" method - put a piece of black tape over the LED you don't want to see.

<http://elecraft.365791.n2.nabble.com/file/t394210/P1100545.jpg> Hello

I have some internal spurious on my PX3. Is this normal?
How can I get rid of this spurious? Does someone has found the internal
cause e.g. DC/DC converter, clocking etc. and has some suggestions for
shieldings, blocking caps etc.?
I have connected the PX3 to a battery and nothing on the RX I/Q input so
these spurious are only internal.

Great suggestion Tony, and quick.  I knew that the K3S's had the same
firmware revision as I did them at the same time months ago however this
evening I checked the K-PODs and the original one was out of date. It was
easy to update and now both act the same with the D4 LED being on all the
time. At least this explains why they acted differently. Neither radios will
switch the light using the KPLED4 command, perhaps a radio firmware update
would help however at the moment I have no interest in using the LED in a
macro so I'll leave it alone.

Hi John,
I would check the s/w versions of each of the rigs and kpods to make 
sure they are all the same.
try exchanging one kpod with the other and see if the led on stays with 
the rig or the kpod.

My guess is the sw in one of the devices is lower than the other device.

Hi Tim,
I hope you get better soon. There are many control and logging software
programs that you can use to operate your rig from the next room or even
another State. Some are free and some cost $$$. See

Hope the surgery and recovery goes well.?? I doubt there is much RF 
around the transmitter. ? At least there shouldn't be much if any. ? 
However, the radiation from the antenna could be another story.

Hi John,

It's my way of placating the doctors and being compliant. Before this I I
have gone through 4 ICD's and had no trouble but I would rather not rock the
boat too much. No there is no problem with RF in the shack even full legal
power.

Hi Don,

Presently I can barely afford the pigremote let alone another k3 or k3/0. I would mainly be using it from home in the in-house network but if I end up in the hospital again I would like to be able to operate from there also. Trying to cover all bases within my means.

Tim

Hope you make a full and speedy recovery.

It is your aerial which radiates your transmitted signal - therefore
operating the radio from a different room is unlikely to help you, it might
even put you in a higher RF field.

However, if you are able to use the internet to remotely operate a friends
radio across town, that could be a way forward.

It might be worth asking for an RF exposure limit, then doing the station evaluation worksheet from the FCC. 

Links to worksheet here:

http://www.arrl.org/rf-exposure

From the Medtronic patient letter (I?d get an official, current one for your model of pacemaker, of course):

Maintain a distance of at least 6 inches between your heart device and:

? Antennas of cellular phones, amateur radios, ham radios, walkie talkies of 3 watts or less. Maintain a distance of at least 12 inches between your heart device and:
? Antennas of amateur radios, ham radios, marine radios, walkie talkies, citizens band (CB), of 3-15 watts
Maintain a distance of at least 2 feet between your heart device and:
? Antennas of amateur radios, ham radios, marine radios, walkie talkies of 15-30 watts
Maintain a distance of at least 3 feet between your heart device and:
? Antennas of commercial and government dispatch radio equipment of 30-50 watts
Maintain a distance of at least 6 feet between your heart device and:
? Antennas of commercial and government dispatch radio equipment of 50-125 watts

http://www.arrl.org/files/file/Technology/Pacemaker/EMC%20Worksite%20Letter.pdf

?Stay away from RF? isn?t very useful advice in a world full of wi-fi and cell phones. ARRL has info on pacemakers and RF exposure, including specs from Medtronic.

Hi Rooby, 

This is normal for a PX3 that is not connected to anything.  The 'spurs' you
see will not show up once the unit is connected to a KX3 and the KX3 in turn
is connected to an antenna. 

Kindly 73, 

Paul

Tim,

 ???? One of the all software ways to remote operate is: 
http://www.remotehams.com/

You set up the server software on a computer attached to the radio.?? 
You can limit access to just who you want to operate your radio, or open 
it up to pre-approved hams.

 ??? You install client software on the computer you want to operate 
from, its not all inclusive, but does work pretty good.

I seem to have low output on 75 phone. The most power I can put out is 71
watts. I can turn the power knob to 100 watts, but it backs down to 71
immediately. This is into an antenna and a dummy load.

I just checked 160 same thing except I get 83 watts

All other bands seem OK

Hi Tim,
Just saw your other message direct to me.  I'll reply here for anyone else
that may be curious.

I have all of the individual components that go into making a PigRemote
except for a pretty important one, the audio codec board.  When I first
designed PR I decided to not put the audio codec, and it's related
circuitry, directly on the PR motherboard for certain reasons I'll spare
you the details of.  The price for manufacturing that board has gone up
drastically since I last ordered, probably because I always deal in
relatively small quantities and board fab shops like to address something
called a burden rate when accepting jobs.

I'm not sure when I'll have that critical component so I can't make any
guarantees on when I might be able to get one to you.  It'd probably be
faster to ask this group if anyone has one for sale.  The PR was primarily
designed to interface with the K3 and KX3 so there should be more than a
handful out there.  Whether or the owners want to part with them, not
sure.  :)

On a side note, I do have a prototype PR that works with the K3 USB
connection and it's the size of a deck of cards.  I should revisit that to
see about making it a product offering.

73,
Nick

Thank you for your reply, Nick.

I did locate one for sale and have gone that direction.

Sorry, you are having trouble with the parts. I know what it's like designing something then one of the main parts either becomes obsolete or cost rise sharply.

Thank you for your time,

Hi All,
I can set the ref lvl to say S4 on the display (Top Band) and then tune 
around fine but if I switch to another band then the ref lvl will 
sometimes change and others not. if I go through several band changes 
and eventually back to top band The P3 ref lvl maybe back where I left 
it but not always.
Can someone tell me when and how the ref lvl is stored so I can make 
this constant on one band.

I am trying to figure out what is causing RCL REQ to show up on the display
when I am trying to scan channels (channel hopping is what the manual calls
it) and not entering Scanning.
For example, I have 28 memory channels assigned with local 2 meter repeater
freqs. (*) prefix on the labels...

Turn radio on.
Vfo A selected.
Press and hold Band+/RCL.
That shows memory channel 17 flashing on the display.
Press and hold SCAN.
"RCL REQ" appears on the display for a few seconds, and the kx3 does not
begin scanning.

If I dial in *another* channel, then SCAN works. It seems weird that I have
to find a different men channel besides the one that first shows up?
What is "RCL REQ"?
Thanks,
Mike AB7RU

That would be "ReCalL REQuired".
Channel Hopping is different than Scanning.  For Normal Scanning to 
work, you must enter a start and end frequency - except in the case of a 
Live Scan.  Something is missing from your memory channel 17.  Does it 
have an "*" in the label and is it adjacent to the other memory slots 
that you want to have in the Live Scan?

For Channel Hopping or Live Scan, you store the channels in memory with 
an "*" label as you have done.  Then you do a memory recall for one of 
those channels.  The KX3 will go to that channel.  Use the VFO knob to 
hop from one channel to the next.

Are the channels with the (*) in adjacent memory slots? - that is a 
requirement.  You must have a non "*" memory on either side of the 
hopping  (or Live Scanning) group.
Make certain the memory for the channel you start on has an "*" in the 
label.

Subject: [Elecraft] KX1 for sale
Message-ID: <e0eed838-7c21-8ef5-b41b-d0f69ec77a4f@k0dxv.com>

Since acquiring a KX2, the KX1 has remained unused on the self. I don't 
think it's likely that it will ever see any use, so I've decided to sell it.

The KX1 is in excellent condition with no scratches on the case. It 
produces about 3.25 watts on a fresh set of alkaline batteries.

Included is the 80/30 option which has not been built or installed. I 
only ever operated 40 or 20 when I did use it.

I also have the KXPD1 paddle option which is also unbuilt and still in 
its plastic bag.

I might sell the options separately depending on whether someone wants 
just the KX1 or all of it.

I'm not sure what it's really worth. So if you're interested, please 
make an offer off-list.

Thanks and 73,

Doug -- KJ0F

To the list, others may have set up this way:

In my memory channels, the 5 60 meter channels are set up for channel 
hopping, with VFO A being the center of the channel and CW, and VFO B 
being the lower edge of the channel [carrier position], and USB.? 
Selecting a channel then lets me switch between CW and USB with the A/B 
switch.

Changing the VFO A steps through the 5 channels.? However, it does not 
seem to take VFO B with it.? VFO B remains on the first channel selected.

I set the memories up with the K3 Freq Memory editor.? Am I doing 
something wrong, or is this how it works.? If the latter ... any chance 
it could be set to take VFO B along with a rotation of VFO A?

That's the behavior you get when VFO IND is yes.  It will do that on any memory recall -- only retrieve VFO A and not VFO B.

Cheers and HNY,

Ditto John's question.  I really wonder about Med advice if the shack is clean.  I have a friend who gave up hf without discussion of QRPpp, etc.  Chokes, matched antennas, all would seem to be a good route and if you can get a buddy to help check when you are out of the shack?

I understand you being cautious however I am curious, is there RF inside the shack (assuming quality coax and common mode chokes)?

I see the Pigremote is out of stock. Is there any idea when they may become available again? I will be using it with my K3.



I just had a heart transplant along with a new pacemaker and the docs want me to stay away from the transmitter till everything shakes out so I am hoping to control my rig from another room. Itching to get back on the air.
I have been in the hospital since Nov 20th.



Thank you for any help.

It's certainly possible this is a technical difficulty in my mind, it's 
happened before and is increasingly common as I accumulate birthdays:

-- CONFIG-->VFO IND="no"
-- M->V, observe the lowest channel in A and B with *, M->V again
-- 5.332.000/Mode=CW in A, 5.330.500/Mode=USB in B
-- Turn Big Knob up one channel
-- 5.348.000/Mode=CW in A, B didn't change

Thanks Don,
Channel hoping works fine, but the software appears to looking for me to
turn the main vfo to any other men channel before it will accept SCAN. Yes
I have * prefix for each channel that I want "hopped" through. Channel 17
is not the issue, I just used that as an example. I just struck me as odd
that I can't initiate the channel hopping without having to manually select
a specific channel? All I want is to start the scan, why do I have to
select a different men channel than the one that is invoked with the RCL
button. It just struck me as odd is all. Not a big deal, was just curious
why it was forcing s different channel selection before it begins channel
hopping.

Yes, the channels are all in adjacent men slots, 00-28 and all of these use
* prefix. Are you saying I have to assign CH 00 (or 99?)without the * to
get this to scan without giving the RCL REQ?

Thanks, mike

That would be "ReCalL REQuired".
Channel Hopping is different than Scanning.  For Normal Scanning to work,
you must enter a start and end frequency - except in the case of a Live
Scan.  Something is missing from your memory channel 17.  Does it have an
"*" in the label and is it adjacent to the other memory slots that you want
to have in the Live Scan?

For Channel Hopping or Live Scan, you store the channels in memory with an
"*" label as you have done.  Then you do a memory recall for one of those
channels.  The KX3 will go to that channel.  Use the VFO knob to hop from
one channel to the next.

Are the channels with the (*) in adjacent memory slots? - that is a
requirement.  You must have a non "*" memory on either side of the hopping
(or Live Scanning) group.
Make certain the memory for the channel you start on has an "*" in the
label.

You know, if it were me, I would closely follow my doctor?s advice. Being the one-in-a-million case would not be very fun at all. Waiting a short while would be much better than suffering any problems.

Besides, the time might be useful in learning some new technology, such as receiving FT8, designing something new, learning how to operate a remote station, improving my CW (using one of N3WG?s other products) or the like. There is a LOT to do in ham radio without putting a signal on the air!

You could even use a VOIP system called CQ100 which simulates ham radio 
very well - does require a license to use, and provides "ham radio" to 
many many hams that cannot put up antennas or have stations. Sure, it 
not "real radio" but it sure beats watching TV. The use of live posting 
JPG pictures during QSOs is also supported.

Hello Tim.

I feel your pain, as I was recently forced away from my shack as I recovered from a medical procedure.


Follow the doc's advice.  They may or may not know best, but don't tempt fate.

As an aside a friend of mine had a pace maker/defibrillator installed.  Doc told him same thing your doc advised.  Upon further research of the implanted device, the manufacturer confirmed that the implanted device was immune to RF at the frequencies us hams use (at least the HF bands).  Might be worth while to do some research on your own and then consult with your doctor.  Just my two cents worth.


With respect to remote control of your station.  I have employed many methods, many of those mentioned in this thread.  My fall back this time around (for reasons beyond the scope of this thread) is to employ TeamViewer software at the station and also on a laptop or desktop in the other room, etc.  You can download a free copy of Teamviwer as long as you do not use it commercially.  Teamviewer supports audio (stereo no less!) so you don't have to use Skype.  No muss or fuss setting it up (no port forwarding or DMZing).  At the station end the PC will need to be hooked up to the rig for CAT control, audio in/out and a Mic connection.  Easy enough to do.  The most difficult part is setting up audio levels.  The plus side is that once you've got the audio all worked out, the digital stuff like FT8 is a snap to impliment.


If you would like some mentoring, help, advice or just bounce ideas, I'm all ears and willing to guide you.


Congratulations on the new heart and lease on life,  Happy New Year!

Forgot to mention in last post that you will also need something like TRX Manager, Ham Radio Deluxe or other comparable software that will interface with you your rig.  TeamViewer only allows you to see and control what is running on your other computer.  It will not interface with your rig.

Tim,

One helpful feature of the K3 is the availability of TX TEST - that does 
not transmit any RF but all other the transmit controls work.
So you can work at setting the audio levels sitting right next to the K3 
with no danger.  Once you have everything set up, turn TX TEST off and 
move to a safe location.

Mike,

Given that the K3 and KX3 memories work roughly the same, I am guessing 
that the KX3 memories have some quirk related to the K3 "Quick Memories".

In the K3, the first 10 memory slots (00 - 09) are 'Quick Memories' that 
work differently than for the KX3.

So since you are using memories 00 thru 28, do a quick test - remove the 
"*" from the label for memory 09 and try the scan from memory 10 upward.
If that works, it will confirm my guess that you cannot include memories 
00 thru 09 in a memory scan on the KX3.

This is more a reply to everyone and not just one specific person.

I received many great responses with fantastic ideas. Some I have tried in
the past some I have not. 

I would like to thank all of you for your ideas and well wishes. This gives
me hope for mankind.

On the question of RF and pacemakers/ICD's I agree there is a greater chance
of getting hit by lightning than RF affecting the device BUT people do get
hit by lightning so their chances are one. I have had 4 previous ICD's
implanted and have done the research on all and have never had a problem so
I doubt I will with this but right now, after being in the hospital since
Nov 20th, I need to remote control the station for if and when it happens
again. The radio simulator is not appealing to me nor will I pay someone
else to use their station.

Again thank you for all of your great suggestions.

I've been very pleased with my transactions both buying and selling on 
QTH.com. In fact last year I bought my KX-2 used from an ad there and 
sold my KX-1 to help finance it the same day. If you successfully sell 
something there they ask you make a donation that you feel is appropriate.

After I installed the KIO3B board in my K3, I found that running WSJT-X creates 2 or 3 S-units of noise in the rig but WSJT 10 runs quietly.Tried different computers, different cables, different jacks, and scads of ferrites on the USB cable. Nothing seems to help.Has anyone else run into this problem?

That's really odd! It's quiet until the program starts?

What happens if you run 10 and X concurrently? Start up 10 first, it's quiet, then start X?

Audio config on X is identical to 10?

HA!! Try turning off CAT control in WSJT-X. I bet the program is changing something on the rig to make the noise come up.

I tried starting 10 first then X and it didn't seem to help.Yes, the audio config is the same in both programs.I turned off CAT but once again it didn't help.
I asked Elecraft tech support about it but they had not heard of another case and could offer no help.

So, you're saying everything is fine with 10 running, and as soon as you open X the S-meter goes up? If you close X with 10 still running does the S-meter go back down?

When you disabled CAT control in X, did you close the program and get back to the low noise level, then launch it again seeing the S-meter go back up? If so, with X running did you check in the settings to make sure CAT was still off?

When the noise is showing on the S-meter, does unplugging the USB cable make it go away?

That's a good clue, Bert!

So turning off the monitor should kill the noise. Easy to test. 

Funny you mention it. I'm going to test a prospective new monitor today. I'm trying a smaller one so I can fit 2 on the operating desk. I find lots of them are unusable, either the monitor or it's PS generates noise, or they are susceptible to RF.

When full-screen, the waterfall (which is darker) is substantially quieter than the operations screen. While I have figured out how to configure the waterfall palette (I use ZL1FZ palette), I have not found an adjustment for the operations screen.

I wired up my own using this hand switch.

I think Heil sells a hand PTT switch. 

Foot switches are pretty popular, too. I don?t have one, but I?ve seen recommendations on this list.

Normally open push button switch built into an old 35mm film container a hunk of RG-174 coax and a 1/4 inch jack. You could spend a ridiculous amount of money and get the official Heil switch which was built into a pistol grip.

Subject: [Elecraft] PTT switch for K3

I plan to try the SSB QSO party next weekend, and have the adapter for the K3 and a Heil headset ? but I need a remote PTT switch with a ? inch mono plug on one end and a pushbutton switch at the other.  All I have been able to find online are nurse call buttons ? which I suppose would work but the big red cross on the button is off-putting, and because they are made for use in a hospital environment they are expensive.  Anyone suggest a source?

Thanks, as always,

I rolled my own using a small microswitch from my junk box. No larger than a couple of sugar cubes.  A little shrink tubing to cover exposed terminals.  Cost almost nothing and works better than any other I have used.  Force to operate is small so no fatigue.

I strange thing happened to my K3s this morning. Both the mic gain and
compression were set to 0. After trying to get into a net, and not being
heard, I discovered the problem. I did not touch any settings from the last
time I used the rig, which was yesterday afternoon.

Has anyone had this problem?

Ted,

Get a round body pushbutton switch, then look around for something to 
contain it which feels comfortable in your hand - the cap from a Sharpie 
marker or the body of a fat ballpoint pen come to mind.  Drill a hole in 
the far end if there is not sufficient opening to pass the wires, and 
put whatever plug on it that fits your transceiver PTT jack.

If the pushbutton does not stay with friction, glue it in with E6000 
cement, or epoxy or whatever works to keep it in place.

If you don't have such materials available, the cost is much smaller 
than buying a commercial pushbutton PTT switch.  The switch and 1/4 inch 
plug can be found at Mouser - choose economy shipping unless you have 
other parts to order.

73,
Don W3FPR

Ed;

It is easier than fabricating switch bodies. Mouser has several candidates - look at their 502-ED903. It is a nice hand-held switch in a comfortable case, costing about $12. Add wire and appropriate plug (mine has a phono plug for the K3) and you can build a very nice PTT switch for less than $20. 

They also have a new assembly with cable attached for a bit more - something like $160. I don;?t recommend that?

Thanks, Don.  At this very moment I am scanning everything in my office for a suitable candidate . . .   

I just thought of it ? a tennis ball!  Also useful for stress relief when waiting for a nitch in a pileup . . .

You might consider ED913 or E913 which are less expensive than the
ED903.

If you don't want to build something, check out a music store.  The kind 
of foot switch bands use is very rugged and reliable.

Mal, I have after playing with macros and settings.  Just reload last good config file.  That has happened to me twice.  It is like having a computer problem and file corruption can happen.  My first time I sent in and that's an expensive lesson other than mine got a thorough exam and recalibrate.  My macros remained in tact when I did the factory supplied calibrated configuration that I saved.  I have been more religious with my backing up.  Only takes a minute.

Neat idea; thanks for sharing.  

But a 35 mm film canister?  What?s ?film??

    Normally open push button switch built into an old 35mm film container a hunk of RG-174 coax and a 1/4 inch jack. You could spend a ridiculous amount of money and get the official Heil switch which was built into a pistol grip.

    I plan to try the SSB QSO party next weekend, and have the adapter for the K3 and a Heil headset ? but I need a remote PTT switch with a ? inch mono plug on one end and a pushbutton switch at the other.  All I have been able to find online are nurse call buttons ? which I suppose would work but the big red cross on the button is off-putting, and because they are made for use in a hospital environment they are expensive.  Anyone suggest a source?
    
    Thanks, as always,

HI,
Sorry for this post but I am concerned as to what this is.  Two days ago an out of province Honda CRV stopped on my street and put a device in a tree.
Here is a picture...

Anyone know what this is?  I Figure this is a good place to ask since there are people from many areas of technology around here, including military...
Please respond off list.  Should I call the police?
Thanks, Tom

I use my old J-38 straight key wired to a RCA plug that goes into the PTT jack on the rear of the K3. The advantage is that you don't have to pick it up to use it or put it down to type. Easy to wire up too. Buy an audio cable, lop off one connector, dress the leads out and connect them to the key binding posts. 

BTW, have you considered using VOX in the contest?  Completely hands free. 

GL&73,
Brian, K0DTJ

	Switch
Message-ID: <1EED2319-FA3C-4032-BFF0-F6C34353860C@law.du.edu>

Following Kevin Stover?s and Don Wilhelm?s advice ? a normally open push button mounted in a film can or in a Sharpie cap respectively --  I have settled on fitting a button switch into a tennis ball . . . .

		If I drop it, it might come right back
		With their usual vile green color it?ll be hard to lose track of on the operating desk
		Squeezing the ball in between button presses would be good hand exercise
		With a little dexterity and the right placement of the right size button it could be used as either a hand switch or a foot switch
       It would give the operator and the dog something to do when the band goes dead
       
       And, the housing of the switch would be free --

I live about three blocks from a municipal tennis court.  Suitable candidates for a PTT switch body abound on the surrounding sidewalks.  I guess the players around here really aren?t very good.

Cheers,

Ted, KN1CBR

Josh,

See if you can find a monitor with an external power supply that 
produces 12 volts.
If you can accomplish that, connect the monitor to the shack 12 volt 
power system instead of using the switching 'wall-wart' that comes with 
the monitor.

73,
Don W3FPR

If the tree is in your yard, remove the device and saw it open.
However, if the tree is NOT in your yard, remove the device and saw it open.

Eventually somebody will come looking for it, possibly accompanied by the local sheriff.

Adafruit had some nice 12V displays. Most of them are HDMI which 
may be a problem. They change what they have frequently and it's 
been a while since I last looked.

Geocaching ethics require landowner permission before 
establishing a cache. Of course, not everyone does that.

Our local sheriff is a pretty nice guy but this is not the way I would

Have you been operating the K3S using CAT control from an application or 
logging program??? I've found when terminating some programs or the 
computer or radio, during the shut down sequence, things change. ? ? 
Otherwise, values are not as you normally use them or as you left them 
the previous night.

I always first close the application, turn off the radio, turn off the 
power supply, and shut down the computer.? My start up procedure is just 
the? opposite.? Computer on, power supply on, radio on, open the 
application.

Good Evening,

 ?? I got a very strange look from a Gray Jay on Friday.? I was getting 
ready to do the dishes so gave them bits of this and that for a treat.? 
A little popcorn, some oatmeal, a little rice, a heel of bread, and some 
beans.? The beans were what gained me the look.? I had made them with 
three fresh, sliced jalape?os. There is just no accounting for tastes :)

 ?? Twenty meters was long again.? As I was looking for an open 
frequency I heard W1AET very well from Georgia.? There was also a lot of 
noise on it.? Forty meters only had a few "whistlers" pass through but 
was fairly quiet in comparison.


 ?? On 17049.5 kHz at 2300z:

W0CZ - Ken - ND

AB9V - Mike - IN

K6XK - Roy - IA

K4JPN - Steve - GA


 ?? On 7044.5 kHz at 0100z:

W0CZ - Ken - ND

K0DTJ - Brian - CA

K6PJV - Dale - CA

K7TV - Erik - AZ


 ?? From all the weather reports I received it appears the cold snap is 
moving out of the Midwest and South.? Folks in the Northeast are still 
rather chilly.? Makes this a good time of year to sit next to the fire 
in front of your Elecraft rig working a new one.

 ?? Until next week 73,

 ?????? Kevin. KD5ONS

It is hard to tell from the picture how high it is in a tree. If it is for a 
geocache you need to be able to reach it and open it somehow to sign the log 
if it is indeed a geocache. It is the oddest looking geocache container I've 
ever seen if that is what it is.

You don't win anything as such for finding a cache. You get to sign the log 
book, take an item from the cache (if there are items inside it) and leave 
an item of equal or greater value in it.

I've had a Boss FS-5U for many years. Intended for various music applications, sustain for digital piano, triggering sounds, etc. they're very durable and about $29. The chassis is an aluminum extrusion which is keyed so you can attach multiple together.

Tattoo parlor foot pedals are rugged and cheap.  I had to swap out for a 
longer cord but the switch itself is rugged and not too hard to press.

As a near neighbor to Saguaro National Park at one time I knew the Chief Ranger 
on a first name basis. He used to keep up with the geocache website and remove 
caches as soon as they got listed.? As a related activity I recovered some 
benchmarks placed by the Civilian Conservation Corps in the 1930s that hadn't 
been seen since.

For example:

    It looks like a geocache.  Keep an eye on it and you may see folks wandering around with their GPS gadgets in hand looking for it.

Was that due to some legal thing where people aren't allowed to leave items 
in a national park?

It's called "littering" and it is in fact unlawful.

Thanks for this idea. I prefer a foot switch, and I've already had one 
of the Heil switches die on me in less than 2 years of use. Right now 
I'm using one I got from Radiodan.com. The owner is a member of my club, 
and I bought it at our annual HamFest. It looks to be of decent quality, 
but I don't know his source.? Anyway, if this one dies, I am definitely 
going to try a sustain pedal. They typically have a switch which 
switches the operation from on/off to a variable resistance (depending 
on what you are using it for). It should work fine for PTT operation in 
the on/off mode, and they are fairly rugged. I may have to try it soon 
just to see how one would feel in actual operation.

I'm interest in macros or ?? (alternative key assignments) to enable simple tasks I've been accustomed to with other radios. 

The ones that immediately come to mind are
- jump up or down X Khz (2 buttons)
- increase/decrease (or reset to the default) step of the tuning encoder
- switch directly to a specific band instead of having to scroll through them to get where you want to go (6 buttons).

There are others that I'm sure I'll think of as time moves on.

40 years ago, I found a foot pedal for an early IBM Dictaphone at a flea
market. It has a switch in it that allowed the stenographer to press either
side to go backwards or forward when typing the recorded dictation. I wired
both sides together so pressing either side completed the circuit. It is 4'
x 4", made of metal, heavy and has been in use for 40 years. Bob, K9ING

I use my old J-38 straight key wired to a RCA plug that goes into the PTT
jack on the rear of the K3. The advantage is that you don't have to pick it
up to use it or put it down to type. Easy to wire up too. Buy an audio
cable, lop off one connector, dress the leads out and connect them to the
key binding posts. 

BTW, have you considered using VOX in the contest?  Completely hands free.

And if you are manipulate it correctly and wire it right, you can wire it
to a keyer and do iambic keying with your foot.  :)

Eric,

Some of those functions are already present in the K3/K3S - read the 
*entire* manual including the chart of menu functions to see more things 
that you can do.

- jump up/down x kHz, see VFO OFS
- increase/decrease step of tuning encoder, see VFO CRS
- switch to a different band, see "Quick Memories" - I have not used the 
BAND+ BAND- switches in a long time, band switching is a quick two 
button tap.

I set both of my K-PODs to switch to specific bands. I am not at home now
or I would copy the programs however it was easy to find in the manual. If
you cannot find it I can send it to you tonight. I used this feature a lot
over the weekend, it is much nicer than pressing the up/down toggle on the
K3S. I just wish there was more room on the K-POD to label the buttons. I
also really enjoyed having the RIT controls close to the keyboard.

A slight correction - that would have been a foot pedal from the IBM 
"Executary" line.
Dictaphone was another competing company.

Yes, that is a heavy duty footswitch.  I also use one for PTT.

When I used "dictaphone", I was referring to the function of the machine, not the company name.

A slight correction - that would have been a foot pedal from the IBM "Executary" line.
Dictaphone was another competing company.

Yes, that is a heavy duty footswitch.  I also use one for PTT.

Sorta like the Pok?mon crazies awhile back.....

Also, we have a somewhat older version of these new geo whatever things near us.
There's a  6X6 concrete post in the ground with a bronze plaque on it from the US Coast & Geodetic Service 1000 feet from our house.
For about a month, 30 years ago I had an RF transmitter in my barn that was used as a locater beacon for a test program that used doppler shift from its signal as a satellite passed overhead.
 Still have a 2 inch cork in the wall plugging up the hole where the coax fed an outside antenna.

As a near neighbor to Saguaro National Park at one time I knew the Chief Ranger on a first name basis. He used to keep up with the geocache website and remove caches as soon as they got listed.  As a related activity I recovered some benchmarks placed by the Civilian Conservation Corps in the 1930s that hadn't been seen since.

For example:

Subject: [Elecraft] KX2: mono headphone with dual-watch enabled ok?
Message-ID: <CAPHmH=ND+tJVLJX6YoYFSX6oX4gKmqfFxU3SDoLnyhfES2jT=A@mail.gmail.com>

Good morning all,

A recent article in CQ Magazine describes a technique of listening to a
station on two slightly different frequencies (65-80 Hz apart) in order to
possibly increase the ability to copy weak signals. Both frequencies need
to be provided to both sides of the headphones to achieve this effect.

I know that the KX2/KX3 can receive two freqs at once with dual-watch
enabled and that with stereo phones, this puts one VFO in each ear.

My question is, would using mono headphones (with dual watch enabled)
damage the KX in any way? The article is described here, along with the
comment from a reader that prompts this question:

TNX/73,

Eric,

If you look at:

http://nk7z.net/adding-external-keypad-k3/

You will find a short article on adding a 64 key pad to the K3 for macro 
selection.  It assumes you have a P3 as well.

About 1/2 way down the post is a down-loadable spread sheet of macros, 
they don't give you exactly what you wanted, but they may help in 
getting you started in writing macros...

Fred's book is a really useful item to have, as well as Elecraft's P3 
Macro programming manual.

73s and thanks,
Dave

Hello,


I have a K1 with 2 band (30m and 20m) and I would like to know the value (or reference) of L1 -L8 value on the filter board.


L1 L2: 10MHz premix band-pass filters

L3 L4: 14MHz premix band-pass filters

L5 L6: 10MHz RF band-pass filters

L7 L8: 14MHz RF band-pass filters


I can't found the info in the owner's manual.


Thanks for your help,

Pascal,

The parts information is in the parts list for the KFL1-2 kit.
Those variable inductors are 1uHy maximum.

You might want to try an industrial supply company like here:


https://www.mcmaster.com/#pedal-switches/=1b1gd3p

I have used one of the "steel" types for many years.  The "iron types" are 
really rugged but require, in my opinion, to much force to operate.  Mine dates 
back to original use with my Heath SB400.

Untried but they have a PB pendant type too.

They are my go-to company for many items.  Located here in NJ and I can place a 
6PM order and since I'm in the one day UPS zone get it the next afternoon.

Does anyone know what an Elecraft labeled Hex Key is worth? I've got one in
great shape that I'm considering selling.

Hi, I have been noticing that on my P3 and on an SDR IQ hooked to the iF output of either of two K3's,? that there is a small difference in level from one side of zero beat to the other. The noise is about five db higher on the high frequency side than on the lower side. Same on two different K3's, both with upgraded PLL's. I know it is minor, but I am using the K3 as a back end for my EME station and the higher noise tends to cover some signals.? Anyone else noticed it? Any fixes or adjustments??? JPEG available. ?? Thanks, Doug K6JEY

If you live in central Florida, in the general Orlando area, and you are using a K3S, please contact me. I?m in the throes of deciding how badly I want one, but I?ve never seen one in the flesh, let alone in operation.

If you'd be willing to give me a demonstration of yours, I?d appreciate it very much. Fifteen minutes should answer all my curiosity.

Thanks.

This is my once a year request for ?point and click? functionality for the P3. Being able to quickly move a mouse pointer over a signal on the P3 and click to change frequency would be a welcomed feature. When you can?t hear half the signals that populate the local band map, being able to click on what you can actually hear would be a big plus.

Chapter 5 of Fred Cady's Macro Programming, has some of these plus methods of macro testing.  I used some of the content to program mine.There's plenty of references, e.g., setting a frequency is on pages 115-116, etc.

Eric,

Some of those functions are already present in the K3/K3S - read the
*entire* manual including the chart of menu functions to see more things that you can do.

- jump up/down x kHz, see VFO OFS
- increase/decrease step of tuning encoder, see VFO CRS
- switch to a different band, see "Quick Memories" - I have not used the 
BAND+ BAND- switches in a long time, band switching is a quick two
button tap.

Usually most guitar players have an abundance of? "stomp boxes". Of 
course select one that doesn't have all the electronics and controls 
included inside.

I checked with a local music and instrument store and asked about one 
that was perhaps junk just to get the base.? The fellow asked what and 
why I wanted one.? I told him and he handed me a used one, needed 
cleaning and a paint job, and said, just change the connector to what 
ever your need.?? Nothing better than a Free Of Charge stomp box.? I'm 
happy.

I've been using foot switches since 1957, with my Viking II and 75A-4. 
The first one was somewhat crude.
IMHO, the Linemaster series of industrial-strength footswitches is the 
best. Very rugged, but responds to a light touch.
Mine gets used a LOT, and I expect it to outlast me!

I just looked at my K-POD.  To switch bands I used the following codes:

10m   BN09;
15m   BN07;
20m   BN05;
40m   BN03;
80m   BN01;
160m  BN00;

Thanks for the QSO and mult on Saturday night

I set both of my K-PODs to switch to specific bands. I am not at home now
or I would copy the programs however it was easy to find in the manual. If
you cannot find it I can send it to you tonight. I used this feature a lot
over the weekend, it is much nicer than pressing the up/down toggle on the
K3S. I just wish there was more room on the K-POD to label the buttons. I
also really enjoyed having the RIT controls close to the keyboard.

The ones that immediately come to mind are
- jump up or down X Khz (2 buttons)
- increase/decrease (or reset to the default) step of the tuning encoder
- switch directly to a specific band instead of having to scroll through
them to get where you want to go (6 buttons).

There are others that I'm sure I'll think of as time moves on.

Have you contacted the Elecraft Hex Key Collectors' Association (EHKCA) website, or joined their e-mail list on QTH.net?

Frankly, run-of-the-mill garden-variety Elecraft hex keys seldom bring more than a C-note, even when accompanied with the original Elecraft sales receipts, owner's manuals, and authenticating certificates.  It's common knowledge in the Elecraft hex key collector community that only low serial-numbered hex keys with the winged Elecraft emblem bring top dollar or trade.  If you are the lucky owner of one of those extremely-rare and highly-desired beauties, announce details on the list I noted above or on the "Classifieds" page of the EHKCA website.  You may be able to arrange even trade for a new K3s/KPA1500/P3 combo!

Good luck!

Mine must be REALLLLY valuable since the Elecraft logo is incorrectly

Doug,

I have two K3s and two SDR-IQs and don't see this on either.? How wide are you 
sweeping?? Across a 190 kHz band there is a little difference probably 
attributable to filtering in the K3, but it's really minor and more-or-less 
symmetrical.? I usually use 50 kHz in the menu and then sweep only 20 or 30 kHz.

Wes? N7WS

I know it is minor, but I am using the K3 as a back end for my EME station and the higher noise tends to cover some signals.? Anyone else noticed it? Any fixes or adjustments??? JPEG available. ??

I have one of the original PAR end fed half wave antennas prior to LNR taking over production and sales.


Everything is present EXCEPT the little matching network that couples the EFHW to the radio. I tried contacting LNR to obtain a new one but they told me that they couldn't do that, BUT they would sell me a new version  of the complete antenna for the paltry sum of around $80! I said "no thanks" and hung up the phone.


I am after the schematic or the best guess of the components and parts placement that will resonate this 40-30-20M antenna. It's not rocket science but it's close!! As I understand it these antennas are fairly high impedance wise, so I need some kind of matching network to bring that down to around 50 ohms for the KX2.


Failing that path, has anyone hooked an EFHW to the internal ATU with good results? I would also include a cut to frequency ground radial that I would lay out below the antenna. That would be the easiest thing and simple to employ.


Over the next 10-12 days I am planning on doing some portable operating from MD and PA. Taking the KX2 with me and hope to get some operating time between family obligations.


Opinions, observations, ideas please.

I built my own with a pushbutton switch that had what seemed 
like a good feel from a ham fest.

It consists of two wedges of wood to set the angle of the pedal, 
a base of 1/4" plywood with the switched recessed so just the 
top is above the base, and a piece of 3/16" plywood hinged to 
push the switch with the foot. The hinge is a piece of gaffer's 
tape -- duct tape would also work. I may have to replace the 
tape sometime, but it has held up well for about 4 years.

After I used it for a while, I added a "dead pedel" on the right 
side. This lets me rest my foot on the dead pedal and just twist 
the foot it to transmit. I would look for a dead pedal feature 
in any commercial pedal, since holding my foot up caused sore 
muscles after a while.

Some of the musician pedals can be switched between push-on, 
release-off and push to toggle on/off. If you talk for a long 
time, this option might be attractive and a substitute for a 
dead pedal.

Try a 64:1 balun.  That's what our antenna expert at our club suggests for
resonant end fed antennas.

I've had success with this unun on my K2/10 and a FT-897 at 100 
watts/external tuner. Used a random length of wire tossed up in a tree, 
haven't tried to make one resonant.

Message-ID: <ad5fd55d-b56b-5571-7116-ea28854bc54b@foothill.net>

I have a K3/100.? For CW and RTTY below 10 m, I normally run a 20 KHz 
span with the ends of the span on even 20 KHz boundaries [3500-3520, 
3520-3540, etc].? I'm in Fixed Tune mode where the span edges remain 
fixed and the VFO cursors move as I tune.? Tuning off the edge results 
in a full 20 KHz shift [IAW, a new 20 KHz span].

When I change bands using BAND UP/DN, the P3 seems to preserve this 
configuration from band to band.? The same seems to hold when I use 
direct frequency entry.? However, when running N1MM+, typing a frequency 
into the call sign window will go to that frequency on the radio but 
will put the span edges at odd 20 KHz boundaries [3510-3530, 3530-3550] 
and sometimes at 3515-3535.

Does anyone know how the P3 recalculates the span edges on band changes 
from an external control program?? If I knew, I might be able to compensate.

Consider what W8JI says about end fed ants.  He also addresses the PAR.
Interesting observation from one set of calcs he did- Maximum antenna 
current is .758 amperes, while the coax common mode current maximum is 
actually 1.02 amperes!

https://www.w8ji.com/end-fed_1_2_wave_matching_system_end%20feed.htm

Without a decent counterpoise, the Z you see could be anything.  What 
you see will be a function of your particular counterpoise.

Yes it can work with the KX2 with no coax feed line and those power levels.

His remarks about using high power are interesting.

Dennis, Mel and Rich:


Thanks for the quick replies. I have googled the EFHW and have some baseline info to play with.


My original idea was to use the internal ATU of the KX2 coupled directly to antenna and put a counterpoise on the ground side of the a rig's antenna connector.


I have the Super Antennas MP-1 with extra extension mast sections and a bunch of radials, so in the grand scheme of things if I can't get the EFHW to work properly I can  revert to the MP-1.


The QRP Guys have a neat little tuner that I might try. My parts bench stock has dwindled over the last few years and Radio Shack is no longer with us for parts and components, so it looks like I will be scrounging!!

I think the following issue may be part of the same problem.

For the WARC bands, I like to have the P3 set up to show the 
whole band. When I use wsjt-x to switch to 17M, the P3 changes 
from showing 100KHz between 18.068 and 18.168 to showing 100KHz 
from 18.100 to 18.200. Annoying.

This "feature" has been commented on in the past. It appears the P3 
automatically recomputes the display limits in Fixed Tune mode if the K3 
frequency is changed via the RS232 port (i.e., the P3 gets the frequency 
change command). When I use the Band buttons on the KPA500 to change 
bands the P3 display limits don't change -- probably because the 
frequency change is commanded by way of the serial bus between the 
transceiver and the amp.

I also find this quite annoying and would like the P3 to respect my 
manual settings when a QSY is commanded.

That definitely will not work:? The impedance of the EFHW is much to 
high for any internal ATU to match.? The 64:1 balun may work, though I 
haven't tried one.? QRPKITS has a QRP tuner, but it works only on a 
single band.? Most any of the external antenna tuners will work, though 
they may be lossy.

The best solution, I think, is to build your own L-network tuner.? One 
coil, a 3-position switch, and one variable capacitor.? You don't have 
to get a perfect match, just within the range of the internal ATU, like 
3:1.? Once you find the right coil tap positions, the internal ATU 
should be able to handle the small mismatch with different antenna 
installations, etc.

It may seem like a lot of trouble, but if you can match the EFHW, it's 
just about the most effective simple wire antenna you can use.

I agree with what has Scott has written.  EFHW from what I have read and experienced, generally have ~ 3000+ ohm impedance at feed point.  Thus the need for an adequate transformer, most usually to match 50 Ohms.  I use one on 160 and 80 meters (where it is really a full wave) at home by using a toroid and windings with a tap.   I do use a tuner for slight changes when the length doesn't match the frequency I choose to use.  A counter balance removes the idea and radiation of the EFHW.  A very short ground is important to remove static potential on the low side of the coil to protect equipment.  If you google EFHW's you will finds loads of great stuff to read and help you.  Good luck.  

I happen to like the ones I am using, but did buy a factory built coil after I found my personally built could not give a native match at the desired freq as my toroid did not have adequate specs despite what I had calculated would work.  The site I got my initial info from was incorrect and the co I bought the toroid and wire from had an inadequate description.  Live and learn.  My home made works best on EFHW above 40 meters.  

My commercially built transformer in the 160 has very narrow bandwidth.  A remotely operated tuner broadens it but efficiency is  reduced once off the designed frequency. In the design is the selection of wire length and height into the matching transformer.  I do have the multiband EFHW but that requires the appropriate wire length on each band.  I carry the appropriate wires in my antenna kit inside the KX2 large case.   The small gauge silk-like wire is also light and small.  I have a super light 43' collapsible shore fishing pole to string out the wire, versus getting a launched wire stuck in a tree and then be potentially guilty of littering in the state park where I like to hang out.

I would be cautious about using a transformer above 40 meters, as the 
stray capacitance may be too large.? I haven't tried it, though, so it 
might work with some transformers.

Yes, you can make a "sniffer" that sends data to the KPA500 from the radio.

This is exactly how I used my KPA500 with my TS-940.

Is it possible to connect a PC to the RS232 of the Kenwood TS-2000 and then
T of the same cable to send just the data (and gnd) from the
TS-2000 to the KPA-500. The logging program on the PC would do the polling
of the TS-2000.

Thanks

As Cliff notes, that is what the SERIAL setting is designed for. If you do this, set RADIO to SERIAL,  the RS232 X setting for the radio?s data rate,  and then set SER POLL to OFF. Setting SER POLL to ON will allow you to use the radio and KPA without the computer.

Remember, the KPA is listening to the data coming FROM the radio. Also, when SER POLL is ON, the KPA expects to talk on the serial port to the radio. It is disconnected from the data line going to the radio when SER POLL is OFF so as not to interfere with the computer.

If you run into any problems, just ask!

For years, we've been winding our transformers wrong. The windings 
should be on opposite sides of the core, so that capacitive coupling is 
minimized, NOT laying on top of one another. In a ferrite materialthat 
is SUITABLE for use as a transformer, the mu is high enough that a VERY 
high fraction of the flux in? toroid is contained within the core, with 
very little leakage flux. Windings that lay on top of each other 
maximize capacitive coupling, and thus maximize common mode current. 
Windings on opposite sides of the core minimize common mode current.

Ferrites are semiconductors, so they act as a dielectric. When we place 
windings on opposite sides of a core, we maximize magnetic coupling and 
minimize capacitive coupling, which is from one winding to the core and 
from the core to the other winding. That capacitance is VERY small if 
the windings are widely spaced.

I paid $200 for mine new a few guests ago. Passed it to another CW op when I purchased a real N2DAN Mercury paddle. 

I liked the Hex a lot.  Very stable and solid feel.

Not only winding them wrong but if find more and more being used incorrectly. There is no one baling design that can be used in all applications.  The more common error is the internal balun contained in tuners.

I am running KPA500 remote program. I am connected via RS232.

If the KPA500 is ON (at the back and at the front) then I can HOST 
and CONNECT to the KPA500 and control all functions. When I press the 
POWER button on the KPA500 remote program the KPA500 correctly turns 
off. However, when I press the remote POWER button again the KPA500 
does not turn back on. It seems that the KPA500 RS232 port is not 
active when the KP500 is not ON.  Is this correct? If so how do I 
turn the power on remotely from the PC?

Thanks

Many, many years ago, I wrote a report on a balun I designed. The typist 
(remember those?) changed every "balun" to "balloon", and no doubt told 
all her friends how bad engineers are at spelling.

There is a big difference between what someone asks and what someone is
willing to pay.
There are overpriced things on eBay posted all the time by people trying to
flip them just to make money.
I shake my head many times over the prices I sometimes see things listed
for.
If your going that route just list it as an auction starting relatively low
and let the market set the price.

Select "Completed listings" on the left of the ebay page and you can see
what past items sold (or did not sell) for. Two recently sold for about
$200. That is the real value I would use as a reference.

Ebay has transitioned to a lot of "Buy It Now" and "Best Offer" items
instead of auctions. Many are "new" knockoffs. I have found that the "Best
Offer" items can go for 20% or more below the asking price. The completed
listings won't tell what the selling price of those items were,
unfortunately. Ebay also has quite high fees when you include Ebay and
Paypal fees, but you do get some protections not found in private sales.

Hi All!

If you've asked for a quote or other information from me
in the last three weeks and haven't yet received a reply,
here's the reason....

We ... OM K0PP ... and I live in the country and just before
Christmas suffered a total failure of our water well and
pump system.  Our home, along with the well and pump
dates from the early '60's and it can be argued that we were
overdue for a problem, but how does one anticipate such
failures?  We've spent the time over the Holidays hauling
water from town and "getting by".

Think of all the times you turn a faucet, take a shower or
use the toilet and suddenly find yourself in a situation where
none of this works anymore.

Our pump and well were restored late yesterday (08-Jan)
and things are returning to normal.

As far as I know I have all of your messages and will respond
as soon as possible.  Don't hesitate to follow up if you're
concerned.

FWIW ... aside from the Christmas and New Year holidays
our 62nd year wedding anniversary fell within this period. (:-((

I apologize for the bandwidth, but I wanted all to know what
was going on.

73!

Scott, the hex key is a  copy of a N2DAN on an hex base, produced by Bencher
after they bought the right of N2DAN paddle.
Sure it is a great key.
Vibroplex/Bencher now sell il for 324 $, I think this is adeguate value for
this first class iambic paddle.
I own a great N2DAN paddle, so I think to know the quality of your paddle.

I use an end-fed wire [1/2 wave on 80] from MyAntennas.com run along the 
top of a wood fence about 1.8 meters high.? It has a transformer in a 
sealed box.? The outer surface of the coax seems to serve as the 
counterpoise.? It enters the house through a steel pipe near the ground 
into a closet and thence to the K3/100.

It works as good as one could expect on 80, 60, 40, 30, and 20. 40 seems 
to be it's sweet spot.? It works on 160 ... not great ... but I make 
Q's.? It's OK on 17 and 15, the SFI has prevented much testing on 12 and 
10 although it has SWR minimums [1.3:1 or so] there.? It has 1.2:1 SWR 
on 6 on which I have made exactly zero contacts when the band was open 
this last summer and could hear lots of stations.

Apparently low SWR does not guarantee low loss, however any antenna is 
better than no antenna. [:-)? I'd have to destroy it to see what's 
inside the box.

Going way back to the original post, it seems to me that there is a 
simple answer:

The OP wants something that is very portable, that the KX2 will tune.

The whole balun discussion comes from trying to match a near-infinite 
impedance, and chopping the wire down a bit (or making it longer) is 
going to bring it to an impedance that the tuner can match.

Lotta folks doing that.

I use a switch tapped air inductor with a variable C on one end. It is an L network thus it is reversible and will match either Hi Z or Lo Z loads. This always brings the load to within range the ATU in the radio can resolve a match.

KX2 so not much power.  53 feet of Wireman #534 should tune and radiate 
on most bands with a KX2, and fit in a sandwich sized baggie.  Another 
chunk for a counterpoise.

Simple.  Maybe not perfect, but simple.

That's a trade-off:? You can match it without an external tuner designed 
for high impedance antennas, but the higher counterpoise current will 
waste some of your power.? Also, the high current part of the wire, 
which does most of the radiating, may be closer to the ground.

What part of life isn't a trade-off?

Another answer might be "don't feed it at the end."

I'd be thinking about a quarter-wave of ladder line if I was aiming at 
one band -- always liked J antennas.

A dipole is a lot closer to 50 ohms.

Lots of answers.  All compromises.

The end fed dipole is a good solution for a portable antenna - it is 
relatively easy to get one wire up in the air - tie a line to a half 
filled (or more) water bottle and throw it over whatever support is 
available, tie the line to the antenna end and pull it up.

For the home station where there are more options for supporting the 
antenna, I prefer center fed dipoles over the end fed.
The center feed maintains balance on the feedline (especially if the 
feedline runs perpendicular to the radiator for at least 1/4 wavelength) 
and greatly reduces the chances of RF in the shack - yes a balun at the 
feedpoint is still necessary to keep RF off the outside of the coax.

So while the end fed antennas will work and radiate effectively, they 
can be difficult to tame for RF, but with portable ops, that is usually 
not a big problem because low power is typically used.

Don W3FPR

Is there a fairly complete KPA1500 manual on line anywhere? The only 
one I have found is on the FCC web site from last August.

Fred, I am using the 160 2KWQ version.  The coax is not a counterpoise.  With a 1/2 wave a counterpoise is not used.  You can get 2x the freq from the lowest freq of your wire.  Deviating beyond that adds loss and lack of tuning.  Use an analyzer to determine the intended freq parameters and you can double .  My 160 works great around 1.900 +/- 30 Khz with a tuner, but at the widths I mentioned the efficiency falls off.  Use a ground at the xfrmer.  This is not a counterpoise, just a method to remove static which a 1/2 wave will collect.  As you state, getting a good SWR is not an indication of efficiency.  Height, direction, etc., all matter.

73,
Bill

I use an end-fed wire [1/2 wave on 80] from MyAntennas.com run along the top of a wood fence about 1.8 meters high.? It has a transformer in a sealed box.? The outer surface of the coax seems to serve as the counterpoise.? It enters the house through a steel pipe near the ground into a closet and thence to the K3/100.

It works as good as one could expect on 80, 60, 40, 30, and 20. 40 seems to be it's sweet spot.? It works on 160 ... not great ... but I make Q's.? It's OK on 17 and 15, the SFI has prevented much testing on 12 and
10 although it has SWR minimums [1.3:1 or so] there.? It has 1.2:1 SWR on 6 on which I have made exactly zero contacts when the band was open this last summer and could hear lots of stations.

Apparently low SWR does not guarantee low loss, however any antenna is better than no antenna. [:-)? I'd have to destroy it to see what's inside the box.

Going way back to the original post, it seems to me that there is a simple answer:

The OP wants something that is very portable, that the KX2 will tune.

The whole balun discussion comes from trying to match a near-infinite impedance, and chopping the wire down a bit (or making it longer) is going to bring it to an impedance that the tuner can match.

Lotta folks doing that.

It needs SOME counterpoise, but not much, because the current in it is 
very small.? If nothing else is available, the coax shield will suffice, 
and causes no harm.? The small current at the end of the antenna has to 
have a return somewhere.? I recall old versions of the Handbook showed 
an EFHW fed with open wire, with nothing at all connected to the other 
conductor, and never could figure out how that worked.? I suppose a 
little common mode current in the open wire line.? Later versions, I 
think, showed a short wire opposite the antenna, which at least made 
sense to me.? The point is that the very small current at the end of the 
EFHW will find a return somewhere, and it really doesn't matter.

One way to tell with a QRP radio whether you need a counterpoise is to 
watch the SWR as your put your hand on the case of the radio or tuner.? 
If the SWR doesn't change, you're good to go.? I don't recommend this 
technique at high power levels.

All of this is true ONLY for an end fed antenna which is a multiple of a 
half wave.

The EFHW with open wire line such as you describe is the classic Zepp antenna. They are a single-frequency antenna designed for the Zeppelin airships, hence their name. The radiator is exactly 1/2 wavelength long (electrically) with an electrically 1/4 wave long open wire feeder. At 1/4 wave long the feeder inverts the impedance of the antenna, transforming the very high impedance at the end of the half wave radiator into a low impedance at the transmitter. 

A real-world half wave radiator has an impedance at its end of perhaps 4,000 to 6,000 ohms so, indeed, the current the feed point is very low. The other side of the feed line simply goes to an insulator and is connected to nothing else. However there is always some small leakage current in the insulator so the balance of currents in the feed line is good. 

Of course, such an antenna, like any hunk of wire, can be made to accept power on any frequency and, like any other antenna, works best when in the clear and well above ground where the Zeppelins tended to hang out, HI!

Ahhh yes, the End-fed Zepp.? Trailing wire out the back of the gasbag, 
open wire line to the TX with one end open at the antenna.? Every time 
someone mentions it, I have Hindenburg dreams.

Yes, it does need a small something for a counterpoise, given the small 
current in the high impedance load.? One model I tried on 20m needed 
about 17 cm of counterpoise, but those little currents seem to use 
whatever is available and apparently, there's always something 
moderately conductive available.

Sometimes, I think we forget that we are "Amateur" radio operators.? 
We're not designing antennas for a broadcast station or the VOA.

It's a good idea, but too severely limiting since almost all monitors 
now run on 19V. Thus far the HP 23es is fine. I ran RTTY with it next to 
KPA500 on several bands with no issues. Final test will be pointing the 
6m EME array at the shack and listening. The monitors look really good 
and were on sale at Best Buy for $119!

Hi all,

just small note...

The Hex key is NOT the Mercury copy. 

Bencher is making their own Mercury, N2DAN keys under license and their Hex
key is another product with a bit different concept.
 
The Hex key is simplified paddle. It is high standard paddle but not
comparable with the Mercury, N2DAN.
The fine wide range and proper adjustment of the Mercury N2DAN is completely
"different story" compare to Hex key.

As recently as a year ago, I was still seeing Samsung 24-in monitors 
running from nominal 14VDC supplies. I already own several, and bought 
another to have as a spare. They're 1920 x 1080.

Hexagonal base. The shape of the base confuses mistakes so most do not make
it to the paddles thereby improving sending. It's certainly worth the >$300
to trap errors, isn't it?

I had a HexKey from Elecraft for quite awhile.? It was basically the 
Bencher BY-1 paddle mechanism on a hexagonal base that was somewhat 
heavier [and more stable] than the BY-1 base.? Dave, W8FGU, made me a cover.

A deficiency in both the BY-1 and HexKey was the contact adjustment 
screws.? The threads are fairly coarse and adjustment was very touchy 
and not readily repeatable.

Old injuries and resultant arthritis in my hands was making the HexKey 
hard to use and I now use an N3ZN single-lever which has really helped.? 
Additionally, the adjustment screws are 52 TPI and very easy to get 
right.? The ZN-SL is also on a much heavier base and never moves.? Dave 
made a cover for it too.

Please contact me off-list if interested.

For sale is my K2 (purchased pre-owned from another lister in November 
2017).? It is a K2/10 and fully optioned with 160M option, noise 
blanker, KIO2, KAT2, KAF2, KSB2.? Includes Kenwood mic MC-43S and 
Signalink USB and full complement of written documentation, including 
technical report from Don W3FPR who upgraded it to factory spec on 
August 28, 2017.


Since I only operate HF QRP CW I can't comment on the SSB or digital 
aspects but I can surely state it's a gorgeous CW rig, both 
operationally and cosmetically.


Reason for selling is simple and straightforward:? I want to buy another 
KX3 because I miss CWT and dual watch.


Asking $750 + shipping and insurance via PayPal to CONUS only..


Thanks and 73,?

The Win4k3Suite is the best rig control software I have found.


If your on a MAC, switch to a PC so you can use it.


Not only can I use it with HRD logs, i can connect to the CAT control on WSJT to the virtual com ports provided by the Win4K3Suite and keep both open.   I have my SDR Play connected to the software as well and WOW that makes for the coolest pan adapter on a PC.   I really need a second monitor to watch the whole waterfall while operating at my desk.   I don't do that often but during the RTTY round up it would have been nice...


I run almost everything remote and the few issues I did have in the beginning Tom helped me fix via email support and team viewer when I was too dumb to follow the directions exactly.


I recently preordered the Flex radio and I am going to miss the ease of use the Win4KSuite gives...  I am guessing I won't be able to get Tom to interface with the Flex-6400......    But my Elecraft has no plans to leave either...


Anyways.. Endorsement over... go buy it!

Other than having two paddles for iambic keying, these keys are quite 
different. The BY-1 is fragile and finicky; the Hex key is solid and 
easily adjusted. I've had both and much prefer the Hex key. However, 
both have been replaced by a Scheunemann M-Dirigent (was Schurr Profi).

The most important thing for a radio is a counter poise long enough for 1/4
of the frequency in use.

For many of you before you were born I was in Africa and had a 700 foot
longwire between to poles, huge sag between, L network and a 100 foot
counterpoise.

Never required much tuning on the longwire between 20/15/10 just a touch
with a cheap swr bridge to measure then back to the op position.

So I write this to say to all use as much wire as you can for the antenna
connected to your little radio and a counterpoise as long.

If your KX3 or 2 has the built in ATU so much the better.

COSMIC rule of antennas! The more wire the better. Always.

Understand that a true "long wire" (greater than 1 wavelength) starts to be
directional off of its end (if fed at one end, that's the opposite end).

Ron, 


What you've come to understand is absolutely false except for the 
special case of a long wire close to the ground. That special case 
is called a Beverage antenna that radiates vertically polarized 
radiation off the ends. 


When you raise a long wire antenna more than about 0.05 wavelengths 
above the ground, horizontal polarized radiation becomes dominant 
and the radiation pattern always has a deep null off the ends.

Frank and all,

While it is true that radiation off the end of a long wire is a deep 
null,  The maximum radiation will be at an angle to the wire greater 
than 1/2 wavelength (less than 90 degrees).  That angle will depend on 
the length relative to wavelength.

A look at the radiation pattern of long wires and other Traveling Wave 
antennas will reveal that fact.  The rhombic antenna and V-beams use 
that characteristic for their gain and directionality.

Don W3FPR

Not sure I believe this, lets say a 40 meter dipole, and an 80 meter 
dipole-- the 40 dipole works far better on 40, than the 80 meter works 
on 40, so not always is more wire better.

Now if you are talking long wire, and forgot to state that, I am not 
sure, I'd have to get the modeling software out...

Hi Don, 


Of course you're exactly correct. 


The peak horizontally polarized radiation with respect to the axis 
of a long wire steadily decreases from 90 degrees for a 1/2 wavelength 
or shorter wire to about 50 degrees for a 1 wavelength wire, then 
very slowly decreases to 35 degrees for 2 wavelengths, 30 degrees 
for 3 wavelengths, 25 degrees for 4 wavelengths, etc. 


As the length of the wire increases, the direction of the main lobe 
for horizontal polarization more closely approaches the direction 
of the wire but in never gets closer than 15-18 degrees from the end 
of the wire for any practical wire length. There's always a deep null 
off the end of the wire for horizontal polarization no matter how long 
the wire is. 


If a long wire antenna is carefully designed and constructed to carry a 
pure travelling wave, the angle of the main lobe does NOT change 
relative to a classic long wire antenna; however, the amplitudes of 
the successive lobes can be greatly suppressed in a very carefully 
engineered antenna. Its extremely difficult to achieve travelling 
wave performance in a long wire antenna except for a few special cases: 
- a long wire with a resistive termination connected to a 1/4 wavelength termination wire, 
- a terminated rhombic antenna, 
- a Beverage antenna close to the ground, and 
- a resistively terminated vertically polarized half-rhombic antenna 
(sometimes referred to as an inverted-V antenna in professional antenna 
engineering circles).

I'm not sure this is correct.

I stumbled over a 6M opening on New Years Eve. I managed a FT8 
QSO with VE2XK - FN07 (LotW verified) from California = CM97, 
using my K3 with the internal tuner at 100W into a 160M center 
fed dipole at about 36 feet. I became curious about the pattern 
with this antenna on 6M so I ran a quick cocoaNEC model. It 
shows lots of spikes with a major lobe along the length of the 
wire with about 20 degrees elevation. That lobe was well aimed 
for the contact, as my 160M dipole runs close to east/west.

Frank, you must have misread my comment. 

When end fed, ANY radiator longer than 5/8 wavelength sees the main lobe
skew toward the end opposite the feed point. That's why vertical antennas
designed for low angle radiation are limited by the 5/8 rule. For horizontal
antennas, the effect is not particularly noticeable until the antenna is
more than a full wavelength. That's how Rhombics and V-Beams develop their
directivity.

There may be a null off of the end even for the long wires I've been
involved with. I am speaking of the main lobe skewing TOWARD the end instead
of being at right angles to the wire.

A longer wire produces sharper lobes and, taken to an extreme, the pattern
breaks into multiple lobes. So it all depends upon whether the other station
is aligned with one of the lobes.

Can someone explain the VFWD and VRFL readings in the bottom right of
screen?

When I put out a 15w tune signal, VFWD reads 225 and VRFL reads 2 to 3

Just trying to make sense of the readings

Jack,

For any wattmeter (the one in the KAT500 included), the VFWD and VRFL 
values are related to forward power and reflected power.  Those are raw 
numbers and some math is required to calculate the actual power and SWR.

VRFL subtracted from VFWD can be used to computer the power into the 
load (in this case the input to the KAT500), but you need to know the 
scaling factor that may be unique to the wattmeter.

Similarly, if you divide VRFL by VFWD, you will obtain a result that is 
related to the SWR.

See the formulas associated with SWR in most any book dealing with 
antennas and transmission lines.

73,
Don W3FPR

That axiom was probably true back when the only operation was on low
frequency bands where a full sized ?? antenna was quite impractical.

Not sure I believe this, lets say a 40 meter dipole, and an 80 meter
dipole-- the 40 dipole works far better on 40, than the 80 meter works on
40, so not always is more wire better.

Now if you are talking long wire, and forgot to state that, I am not sure,
I'd have to get the modeling software out...

Plus the fact, the longer the wire, the more the radiation pattern 
approaches the wire axis.  Thus one will gain some along the axis 
direction and loose in other directions.  There is no free lunch.

"long" here means >a few wavelengths.

Yes, of course as Gus said the Bencher BY-1 is far different - single pivot,
spring tensioning, no adjustment. (Set spring tensioning, no adjustments to
make other than desired contact spacing)
It is completely different system compare to Hex key. It is not possible to
mix up them...

I also have a photo of my HexKey from Elecraft and it is *definitely

on the ZN-SL single-lever for my birthday, were it not for my decreasing

BY-1's I still have, were/are touchy to adjust.? I never became

Hi Jack and Don,

As Ron says, VFWD and VRFL are related to forward and reflected power.
Actually, they are roughly proportional to forward and reflected *voltage*.
I say roughly because there is some nonlinearity from the rectifier diodes,
especially at low power. The constant of proportionality is somewhat
dependent on frequency, power level *and * has some unit to unit
variability. That's the stated reason why Elecraft chose not to make any
estimation of actual power levels. But SWR is easily calculated b y the
formula:

VSWR = (VFWD+VRFL) / (VFWD-VRFL)

This formula factors out all the variability mentioned above except the
diode nonlinearity.

In your case this works out as (225+3) / (225-3) = 1.03

Since SWR is all that is required to be known in an autotuner, that's all
the KAT500 is calculating. Actually the calculated SWR doesn't even have to
be very accurate as long is it a monotonic function (no dips or peaks) of
the actual SWR.

To be fair, the KAT500 does need an estimate of forward power since that is
being used to fault if it is too high, but it doesn't have to very accurate.
The forward power is proportional to VFWD squared.

HI Josh:


Another possible source of 12 VDC powered monitors is the Recreational Vehicle industry.  Many RVs have appliances (including TVs) that are powered from the "house battery", which is almost always a 12 VDC system.  And, many TVs have a VGA port on them... plus video, and HDMI, as well as an antenna port.

It's a good idea, but too severely limiting since almost all monitors 
now run on 19V. Thus far the HP 23es is fine. I ran RTTY with it next to 
KPA500 on several bands with no issues. Final test will be pointing the 
6m EME array at the shack and listening. The monitors look really good 
and were on sale at Best Buy for $119!

The trapezoidal base paddles sound like they may be "Scotia" paddles from the 1980's. They are still my 'far and away' favorite paddles with a solid brass base on wood and use magnets instead of a spring for return force adjustment.

Remotehams rcforb works nicely and is easy to set up especially if you
already have a sound card connection for digital modes.

It does require one pc near the rig and another near the bed.

You can easily connect up a paddle using a serial port or usb serial
adapter.

One other note: there is also a remotehams Android app which can also be
used for operating the rig via rcforb on phone.

One of the simplest ways is to use HRD at the station; TeamViewer to run the station remotely and Skype for audio (I use the SignaLink for that for SSB) from a laptop, tablet or smartphone.   (I also run the KAT and KAP utilities, so I have complete station control.)

The software is free (after the initial HRD support purchase) and I?ve used that method all over the continent and Hawaii.  The only issues are satellite latency if the local internet access isn?t wire based (not an issue for a LAN).

What on the mac are you trying to log to? The native WSJT-X log file, or an
external logging program?

WSJT-X prompts me to log to the WSJT-X log files after every QSO for FT8,
just like it does for JT65 & JT9. I haven't messed with trying to also
automatically get those log entries into a "real" logging program, but JT
Bridge should be able to do such a thing.

Let me tell you what I observed with 700 feet of long wire.

QSB disappeared. What faded on one end was rocketing in on the other end.

I pointed the antenna at the USA from Kenya. There was nobody in the USA
that could not hear me. I ran 100 watts.

I had lobes going in every direction. I had huge gain forward. Check the
ARRL antenna book. It worked off the end and the front and the side.

It was the best wire antenna I ever used.

Best of all the elephants walked around my old Army Signal Corp 40 foot
poles bought new from Fair Radio Sales. That's right. The Elephants walked
around the poles. The sag in the middle was pretty deep but still taller
than an Elephant.

The longer the wire the more forward the gain. The better the lobes.
I never used a better wire and if I had to do it again I would do it again.

73 all, Bill

The science is simple. The more wire hanging out the more signal radiating.

There is only a fixed amount of total energy contained in all the lobes 
of an antenna.? You almost definitely did get lots of lobes ... but you 
also got lots of nulls that exactly offset all those lobes.? You just 
never heard the the hams that were in those nulls and they never heard 
you.?? Whatever you gain in one or more directions is sacrificed in one 
one or more other directions.? This is basic physics.

More lobes is not necessarily better.? In fact, taken to the extreme it 
is self defeating because a very large number of lobes (assuming they 
were somehow all of equal strength as you stated) begins to approximate 
a unidirectional antenna with no azimuth gain in any direction.

Just for grins I modeled your 700 foot antenna in EZNEC+ and on 20m it 
gave a maximum gain of about 9 dbi in a fairly narrow lobe at 16 degree 
elevation in both directions along the axis of the wire.? It also gave a 
total of 36 other sharply narrow lobes arrayed symmetrically in all 
other directions, each with a gain of about 6 dbi.? Between each lobe 
was a deep null of around minus 10 dbi. This was all at the same 16 
degree elevation angle ... there were literally too many lobes to count 
on the 3D pattern, with lots of lobes and nulls at every azimuth and 
elevation angle.

A simple dipole at the same 40 foot height would have given similar gain 
with a much broader lobe (both azimuth and elevation) in the two main 
directions, but of course without the multiple smaller side lobes.? 
Three poles and two perpendicular dipoles would have given better 
overall single band results ... the only advantage of the long wire 
being that it gives a similar pattern along with similarly ugly match on 
multiple bands.

The macOS version of WSJT-X logs contacts in the same way?as the Windows and Linux versions.
I assume the version of macOS you are running is reasonably up to date, preferably Sierra orHigh Sierra, and that you installed WSJT-X as a user.
If you are having problems logging, check WSJT-X -> ?Preferences to make sure you have things setup the way you want/need.
If you want to review recent QSOs, then you can go to WSTJX -> File -> Open log directorywhich will bring up a Finder window for the directory where all of the log files reside, which istypically /Users/yourusername/Library/Application Support/WSJT-X. Simply click on "wsjtx.log" andit will bring up the log file for you to inspect/search.
If you are looking to automatically log your WSJT-X QSOs directly into your logging program, youshould consult your logging program's documentation. I use RUMlog, published by Tom, DL2RUM,and there are a couple of settings within it that allow the two programs to communicate via UDPpackets within your system, and the integration is wonderful - I leave RUMlog running in the background,and operate primarily in the main WSJT-X window (while watching the waterfall on its?window, primarilyto pick a clear transmit frequency), and when I actually make a QSO, and WSJT-X prompts me tolog it (because I have set my WSJT-X Preferences to do so), and I click on the "Log It" box, it sendsthe information to RUMlog, which then logs it as if I'd entered it myself. The only thing I have to dofrom there, manually, on RUMlog is to ship the QSO up to LoTW if I so choose.
Support for WSJT-X is available on the Yahoo! Group as documented in the Help files, and theyare very responsive.
Apologies if the formatting of my message looks?weird on the mailing list - it's a Yahoo! problem,which tends to mangle line endings and paragraphing.

Hi,

it is not about the antistatic only...
It is about the conductivity and dissipation etc.

Generally speaking, the performance of ESD mats depends on the material from
which they are constructed. That material can include:

?      Homogenous mats are comprised of either vinyl or rubber. These mats
typically offer the highest amount of electrical absorption because they are
composed of a single, solid block of the same material.

?      Three-layer mats, usually made with vinyl, offer a decent level of
electrical absorption. Their strongest advantage comes in the form of an
increased level of comfort to the worker standing on the mat.

?      Two-layer vinyl mats offer the electrical absorption capabilities of
three-layer mats at a significantly reduced cost.

?      Two-layer rubber mats provide both a high level of electrical
absorption and an immense level of comfort to workers. Two-layer rubber mats
are also extremely chemical-resistant. However, this multipurpose mat comes
at a somewhat higher cost than others.

Vinyl mats tend to be preferred in situations where cost is the ultimate
priority, whereas rubber mats are better for situations where a high level
of chemical or heat resistance is required. With that in mind, it?s likely
that many companies will require both vinyl and rubber mats for use in
different parts of their manufacturing facilities.

Subject: [Elecraft] SNR improving on CW signals
Message-ID: <1515752002234-0.post@n2.nabble.com>

Hi all,

there is an interesting article about the improving perceived loudness by
6dB and that of the background noise by 3dB, resulting in a net 3dB
improvement in the signal's SNR on CW...

https://plus.google.com/100312042524727617304/posts/gtNciqaFQk5

BTW: be careful as there are a little mistakes in frequencies difference for
fourth chord etc.
1) CQ Jan 18, page 17, Fig.1. (b): 697Hz-523Hz=174Hz (almost fourth chord)
and NOT 80Hz as described
2) CQ Jan 18, page 18, Tab.1: eg. E4-F4=19.6Hz NOT 19.55Hz,
F#/Gb-F5=41.533Hz NOT 42.53Hz etc.

Is there somebody who configured his K3 for that and tested it already?

Bill,

The situation you had was essentially a point to point communications 
setup. It worked well for you. Commercial installations long ago used 
long wire antennas (including rhombics) pointed in specific directions 
to assure good point to point communications.  It isn't a "work all 
directions" setup.  The posting given by another reporting EZNEC results 
is a true description of where the energy goes with a many wavelength 
long wire.

This is not to say you can't work other directions.  With appropriate 
propagation and with your DX prefix, people would be workable off the 
sides.

I think this tread started out with somebody wanting to have a portable 
antenna for use in many locations.  It is pretty clear that a point to 
point antenna would not be appropriate for his application.  Something 
more omnidirectional would be.

I don't believe the mat is anti-static any more than my wife's silicone baking sheets.
They claim the tweezers "adopts anti-static design to prevent static damage to electronic components", whatever that means.  No wire attachments are shown for the tweezers.
I don't think this is what you want for ESD sensitive work.

There is only a fixed amount of total energy contained in all the lobes

you.   Whatever you gain in one or more directions is sacrificed in one
one or more other directions.  This is basic physics.

More lobes is not necessarily better.  In fact, taken to the extreme it
is self defeating because a very large number of lobes (assuming they
were somehow all of equal strength as you stated) begins to approximate
a unidirectional antenna with no azimuth gain in any direction.

Just for grins I modeled your 700 foot antenna in EZNEC+ and on 20m it
gave a maximum gain of about 9 dbi in a fairly narrow lobe at 16 degree
elevation in both directions along the axis of the wire.  It also gave a
total of 36 other sharply narrow lobes arrayed symmetrically in all
other directions, each with a gain of about 6 dbi.  Between each lobe
was a deep null of around minus 10 dbi. This was all at the same 16
degree elevation angle ... there were literally too many lobes to count
on the 3D pattern, with lots of lobes and nulls at every azimuth and
elevation angle.

A simple dipole at the same 40 foot height would have given similar gain
with a much broader lobe (both azimuth and elevation) in the two main
directions, but of course without the multiple smaller side lobes.
Three poles and two perpendicular dipoles would have given better
overall single band results ... the only advantage of the long wire
being that it gives a similar pattern along with similarly ugly match on
multiple bands.

If there's no ground connection to the mat itself, then for ESD it's about 
as useful as a chocolate coffee pot!

Google for groups on the 'net who sell mats and have properly evaluated 
them. The ideal thing is a proper mat with a (resistive) ground connection 
and a stud to connect wrist strap. That way if you pick up ungrounded 
tweezers or any other conductive tool, you will be (ESD) grounded and so 
will the tool.

Unless you can find the correct item elsewhere, then purchase the exact same 
thing via Amazon, I would not trust ANY claims by Amazon sellers.

You get what you pay for!

Hi,

yes, exactly. The silicone only means insulating with low charging but there
is no way to 
dissipate nor conduct the charge away to ground.

The standard ESD mats has the top dissipative layers and bottom conductive
layers mats connected to central ground and equipped with wrist strap.

I don't know much about antennas, but in the late 60s or early 70s I worked
a station on 20 meters with a 10 mile long (long wire antenna).

That was KC4AAD in Antarctica. I don't have the QSL card I got back then,
but was a picture of part of the antenna. I know it was 20 meters, because I
only had a 20 meter antenna. A 3El wide spaced monobander up about 35 feet.

Just for kicks, I modeled it with a 1/4 wave counter poise up 12' up 
from ground. 14 MHz.

Unfortunately where ground is a question.  What the parameters for 
"ground" is a good question.  Snow doesn't look like earth.

Anyhow the impedance came out 11470 ohms +j 17880.
The horizontal antenna pattern was along the axis with a beam width of 
3.8 degrees and a gain of almost 15 db

The vertical pattern peaked at 3 degrees and straight up 5 dB down.

I wouldn't touch that type of mat if you are working with static sensitive 
electronics.

For a proper ESD mat take a look at this:
     https://www.ebay.ca/sch/i.html?_nkw=272253182084

A top half that is dissapative, can't easily be punctured, can handle high 
temperature for a short time without burning for a short term. The bottom 
half is conductive. It has attachment points for a wrist strap and for the 
wire that should be connected to ground to get rid of any charge build up.

The macOS version of WSJT-X logs contacts in the same way?as the Windows and Linux versions.
I assume the version of macOS you are running is reasonably up to date, preferably Sierra orHigh Sierra, and that you installed WSJT-X as a user.
If you are having problems logging, check WSJT-X -&gt; ?Preferences to make sure you have things setup the way you want/need.
If you want to review recent QSOs, then you can go to WSTJX -&gt; File -&gt; Open log directorywhich will bring up a Finder window for the directory where all of the log files reside, which istypically /Users/yourusername/Library/Application Support/WSJT-X. Simply click on "wsjtx.log" andit will bring up the log file for you to inspect/search.
If you are looking to automatically log your WSJT-X QSOs directly into your logging program, youshould consult your logging program's documentation. I use RUMlog, published by Tom, DL2RUM,and there are a couple of settings within it that allow the two programs to communicate via UDPpackets within your system, and the integration is wonderful - I leave RUMlog running in the background,and operate primarily in the main WSJT-X window (while watching the waterfall on its?window, primarilyto pick a clear transmit frequency), and when I actually make a QSO, and WSJT-X prompts me tolog it (because I have set my WSJT-X Preferences to do so), and I click on the "Log It" box, it sendsthe information to RUMlog, which then logs it as if I'd entered it myself. The only thing I have to dofrom there, manually, on RUMlog is to ship the QSO up to LoTW if I so choose.
Support for WSJT-X is available on the Yahoo! Group as documented in the Help files, and theyare very responsive.
Apologies if the formatting of my message looks?weird on the mailing list - it's a Yahoo! problem,which tends to mangle line endings and paragraphing.

I think might (in some way) OT except that folks here build kits?..

No knocks on ebay - like everywhere else, if you are careful, you can get what you pay for.  I?ve found great things there for very little money on ebay.

For comparison, a range of bench mats from Newark:
http://www.newark.com/c/static-control-site-safety-clean-room-products/esd-protection-products/anti-static-mats

I?ve installed and used a wide range of antistatic mats on benches (and far less optimum locations including on the deck, in the snow, and the ground) in lots of places for work.

I bought a pair for my benches at home and a 3M portable (field kit):
https://www.cdw.com/shop/products/3M-TELCOM-STATIC-FIELD-SERVICE-KIT/2316620.aspx
with seems to come from SCS these days (are they spun off of 3M?)

Whatever you buy, don?t forget (the obvious, but often overlooked):
- at least one wrist strap
- and you have to ground the mat

I?m relatively new to the amateur radio hobby and I find it fascinating that many of us (this is the Elecraft list after all) are willing to pay nontrivial money for the best radios but at least some find it hard to justify paying for quality for the supporting infrastructure/equipment.

YMWV,

This could account for why my 2 wavelength Beverage never seemed to 
perform well on 80 when we lived in Auburn CA.? Elephants are very 
uncommon in the foothills of the Sierra Nevada.

I wintered over at Byrd Station in 67-68.  The "Long Wire" VLF station was, as I remember, about 11 miles away from the main Byrd station to get away from noise sources for the research that was being done.  Several of us at Byrd walked out there one day (although I guess it was night, seeing as how nights were 4 months long).  I'm pretty sure the 10 mile antenna was for receiving but KC4AAD might have used it for transmitting.  My own station, KC4USM, used a 700' long vee beam, on the ice.  "Ground" was something like 7000' below, 2000' below sea level.

Cheers and 73,

Fred KE7X OAE

Just for kicks, I modeled it with a 1/4 wave counter poise up 12' up
from ground. 14 MHz.

Unfortunately where ground is a question.  What the parameters for
"ground" is a good question.  Snow doesn't look like earth.

Anyhow the impedance came out 11470 ohms +j 17880.
The horizontal antenna pattern was along the axis with a beam width of
3.8 degrees and a gain of almost 15 db

The vertical pattern peaked at 3 degrees and straight up 5 dB down.

Taking the headphones off and laying them on the desk seems to boost the 
SNR of a CW signal significantly. Helps with closely spaced QRM too.? 
It's been known to RO's since the "olden days."

Also, I believe ESD wrist straps should have something like a 1 meg ohm resistor in the ground connection to mitigate direct (and potentially fatal) shock to ground while allowing the bleed off static charge.  A direct connection to ground is hazardous!

For transmitting, that 10-mile long conductor would be close to an 
end-fed full-wave, and perhaps a flame-thrower, for SAQ [17 KHz].? On 20 
meters, it would be an end-fed 805 wavelength conductor [wonder how that 
would model in EZNEC?], all the power dissipated in the first few 
hundred meters of the conductor, and most of the conductor in the far, 
far, far field of the antenna that is actually radiating.

Actually, I have the urge to waste a little time, QRX, I'll try it.

An antistatic mat 'worth its salt' will have a ground connection and the 
distributed conductance of the mat material provides safety from the 
direct ground.
Yes, wrist straps are different, they have a large resistor (about 1 
megohms) in series with the ground connection.  Mine connect to a 
'button' on the rear corner of the mat.

I have a quality mat covering much of my workbench as well as a wrist 
strap.  My commonly used tools rest on the mat as well as the radio 
being worked on.  Other less commonly used tools do not live on the mat 
but are brought into contact with the mat for a bit of time before 
touching them to any internal part of the radio.

I believe these are good antistatic work practices.

I follow Elecraft Engineer Paul's advice (after he studied the electrical characteristics of a number of mats) and avoid any mats that do not specify their ohmic values. Too often, such mats better insulators than static dissipating devices.

So I'd at least e-mail the manufacturer for electrical specs.

A mistaken idea that many Hams get is that a wire antenna has no radiation in the "nulls". For example, a half-wave wire is often thought of as having no energy radiated off of its ends. There is LESS off the ends, but a real-world wire has some radiation in ALL directions as Dave notes. It's just stronger radiation in some directions. 

A real long wire (many wavelengths) is easy to match since the longer a wire is, the smaller the impedance excursions across the RF spectrum. The hardest to match are wires a half wavelength (or less) long. However, most compact ATUs are limited in matching range based on simple physics. Their small size cannot tolerate the huge RF currents and voltages frequently encountered even at moderate power levels. There's a good reason why the old time "antenna tuners" (matching networks) were so huge. It's just a matter of basic physics. But today most of us use antennas that offer an feed point impedance limited to the range our ultra-fast, super-smart "automatic antenna tuners" can handle.

There is only a fixed amount of total energy contained in all the lobes of an antenna.  You almost definitely did get lots of lobes ... but you also got lots of nulls that exactly offset all those lobes.  You just never heard the the hams that were in those nulls and they never heard you.   Whatever you gain in one or more directions is sacrificed in one one or more other directions.  This is basic physics.

More lobes is not necessarily better.  In fact, taken to the extreme it is self defeating because a very large number of lobes (assuming they were somehow all of equal strength as you stated) begins to approximate a unidirectional antenna with no azimuth gain in any direction.

Just for grins I modeled your 700 foot antenna in EZNEC+ and on 20m it gave a maximum gain of about 9 dbi in a fairly narrow lobe at 16 degree elevation in both directions along the axis of the wire.  It also gave a total of 36 other sharply narrow lobes arrayed symmetrically in all other directions, each with a gain of about 6 dbi.  Between each lobe was a deep null of around minus 10 dbi. This was all at the same 16 degree elevation angle ... there were literally too many lobes to count on the 3D pattern, with lots of lobes and nulls at every azimuth and elevation angle.

A simple dipole at the same 40 foot height would have given similar gain with a much broader lobe (both azimuth and elevation) in the two main directions, but of course without the multiple smaller side lobes. Three poles and two perpendicular dipoles would have given better overall single band results ... the only advantage of the long wire being that it gives a similar pattern along with similarly ugly match on multiple bands.

Right. The mats are usually grounded directly since they have a fairly high internal resistance, while the wrist strap that features a metal contact to the user has a 1 meg resistor in series.

Also, I believe ESD wrist straps should have something like a 1 meg ohm resistor in the ground connection to mitigate direct (and potentially fatal) shock to ground while allowing the bleed off static charge.  A direct connection to ground is hazardous!

Ron, love your comment.  I use EFHW and it is amazing the confusion over how they work.  Got to have a great transformer and a chosen antenna length and stick to it and perhaps a multiple that fits.  My 160 EFHW is made for 1.900 and works well at 3.800 in certain directions on either band.  I have do use a remote tuner for slight deviations and also compare two different dipoles to pick the best one to use.  The 160 is a c shaped set in the trees.  Insulated wire.  Now to get it isolated with insulators. Next spring... too much cold weather and snow to deal with.  :-)

For reasons of family convenience, I have started to run my KX3 remotely in my Loft using our WiFi Lan from a computer three floors down.

I have assembled a Raspberry Pi 3 in a case with a 7? LCD screen.  The inbuilt wifi on this puts in on my home network.

Using ser2net on the Raspberry Pi, I can run KX3UI on my iMac three floors down ( configured as  a Piglet ).
This is well documented elswhere

I then  set up a virtual screen screen session with the Rasbian?s RealVNC and set the resolution to 1024x800.

I can then run WSJT-X on the remote Raspberry Pi in the higher res screen session upstairs , but see and operate it on my downstairs iMac computer.
I haven't yet managed to get voice over IP for SSB, but if PSK31 or the the JTxx modes interest you then it can be done easily and cheaply.

I haven?t yet setup a remote relay driven by the Raspberry Pi to start the KX3 up. but it should be  an easy job to send a  100msec +9v pulse to the mic input line .   When that happens I can close the loft cover .

All true.? In fact, I was going to mention that for a real world antenna 
there is usually some smoothing between lobes and nulls, especially when 
there are lots of them involved.? I left that out because I didn't want 
to go overboard on my comments.

Another facet is that for any particular azimuth angle that has a null 
at one elevation there might be a lobe at a different elevation angle.? 
3D plots of some antennas look very weird.? I think a lot of yagis look 
like that off the back ... deep null at a low angle but decent energy at 
a higher angle.? I live in Arizona and if I'm running the East Coast in 
CQWPX I can still easily work California off the back.

Well, since you brought up EFHW there is a relevant comment I've wanted 
to make for a while.

An EFHW with a counterpoise wire (which everyone seems to claim is 
important to have) is basically just an extreme version of an off-center 
fed dipole.? A half wave dipole has its lowest impedance at the center, 
where the current is high and the voltage is low.? As you move out away 
from the center the current decreases and the voltage increases, which 
is equivalent to saying that the impedance increases.? As you get to the 
end of the wire the current obviously goes to near zero except for 
capacitive currents while the voltage goes very high ... meaning high 
impedance.? The "counterpoise" for an EFHW is merely an extension that 
puts the feedpoint back toward the center where the impedance isn't 
quite as high.? And as with any dipole, it isn't critical how that 
"counterpoise" is physically arrayed because the current there is small 
so it doesn't affect the pattern much ... just as is the case with a 
dipole with drooping ends.

I think if everyone viewed EFHW antennas as off-center-fed dipoles there 
would be a lot less confusion about how they work.? Just as with an 
off-center fed dipole, an EFHW of the right length would have low 
reactance and high impedance that could be properly matched with the 
right transformer, and you'd need common mode chokes for both to keep 
currents off the shield of the feedline.? The two antennas are different 
purely in terms, not in physical reality or in the radiation patterns 
they produce.

Thanks to everyone who helped me determine what my paddles might be 
worth. I've decided to put them on Ebay, but if any Elecrafters would 
like to make an offer here, I'll certainly consider lower offers than 
the Ebay price.

Thanks for your help! Here's a link to the auction for pics:

I want to setup an audio mixer facility so that I can have at least on 
stereo headphone output and/or a stereo speaker output. That's the easy end. 
:-)

I want to feed it with inputs from the K3S, IC7100, SDR output from a PC and 
possibly a Wouxun multi-band VHF. So a device with at least 4 stereo inputs 
and appropriate level controls.

Has anyone else done this and can recommend a unit that's as RF proof as 
possible. I'm not averse to using a few ferrites, but the system has to be 
clean with 400W HF near it, as I need to listen to the SDR whilst 
transmitting.

Thoughts on how to connect it would also be appreciated, bearing in mind 
that AFAICR the Wouxun only has a low impedance speaker outlet and all 
others must be stereo.

Dave,

All information I have seen says that the counterpoise needed for an 
EFHW is 0.05 wavelength - at 40 meters, that is about 3.5 feet.

If you make it longer than that, it becomes an offset center fed 
antenna, longer than a halfwave, in other words, it is a random length 
wire.  Both the half wavelength wire and the counterpoise wire will radiate.

In the words of another highly regarded ham........."what ever makes you 
feel comfortable is always best".?? Personally I'm pleased with my 
Vibroplex Iambic paddle.? Don't remember what it cost, but are the 
standard model, no chrome base just texture grey finish but with 
upgraded jewel movements.

Just my idea maybe...if you do not plan to squeeze key, then I think a 
single-lever version is superior. In simple terms, 'the finger piece can 
only be in one place at a time.'

True, and the longer the counterpoise, the more it will radiate, right 
into the ground if it's just lying on the ground, so there's really no 
point in a longer counterpoise for the EFHW.

One extreme case is the center-fed full wave, or "two half waves in 
phase".? It has the high feedpoint impedance of the EFHW (actually about 
double) and has a pattern much like a dipole, but sharper.? It has a 
couple dB of gain over a dipole broadside but, of course, less gain in 
other directions.

One thing I? do is make a configuration backup using the Utility.? I 
think is saves this type of data.? In any event, when I get things 
messed up for some unknown reason {usually mine}, I just revert to the 
backup and restore the radio.? All is then well.

Usually do my backups for the radio and computer and a couple of other 
devices, at least once per week.?? More than once I have found that has 
this saved my hide.

Hi,

you can't go wrong with the paddles from Palm Radio. In former times I used
the Mini Paddles but switched to the Palm Single and Pico Single. They are
reliable at every speed and you can adjust them to a very low pressure.

I would start with any model of Rane or Mackie manufactured AFTER about 
1998. That's around the time that both companies acknowledged their Pin 
One Problems and corrected them. I'm recommending these companies 
because their products don't have this problem. Most other products DO.

I once heard LB Cebik give a 'balloon' analogy of directional or gain 
antennas.
He said the radiation pattern is like a balloon - you have to squeeze it 
somewhere to get it to expand in another direction.  There is no overall 
gain, it just directs the radiation in one or more directions at the 
expense of other directions.

Neil,

That all depends on your interpretation of "best".  Please provide the 
parameters for what you want in your paddles, and you will likely 
receive a better answer.
I think my N3ZN single lever paddle is best for me, but it certainly 
cost a lot more than $125.
There is a lot of personal tradeoffs that depend on a lot of things 
related to your tactile sensation.  Some would be able to homebrew 
paddles from 2 hacksaw blades and some contacts salvaged from relays, 
while others would never be happy with something like that.
You might want to peruse the portable paddles used by QRPers if you are 
into obtaining effective paddles at a low price.
If you have the Elecraft KX2 or KX3, you might want to consider the 
KXPD2 or KXPD3 - both are under your target price.

Don W3FPR

You can use whatever terms you want, but physically and electrically you 
are turning the EFHW into an off-center fed dipole when you add the 
"counterpoise" wire beyond the feedpoint.? If you don't agree with that 
you are merely adding to the confusion.

If you add 3.5 feet to a half wave 40 meter dipole it already is no 
longer a true half wave anyway, and you might as well just feed the half 
wave antenna 3.5 feet from one end.

Don't believe me?? I modeled a half wave 40m dipole at 70 feet in 
EZNEC+.? At 67 feet long and fed at the center the feedpoint impedance 
was 66 - j4 ohms.? When I simply moved the feedpoint out to 3.5 feet 
from one end (keeping the total length at 67 feet) the feedpoint 
impedance became 1509 - j1202.? I then added 3.5 feet to the antenna 
(total of 70.5 feet) and fed it 3.5 feet from one end, which in your 
world would be the EFHW with a 3.5 foot "counterpoise."? The feedpoint 
impedance changed to 3317 - j3115 ohms.? Which do you think would be 
easier to match (or easier to understand)??? The 3D radiation pattern 
was indistinguishable from each other in all three cases, of course.

It doesn't matter what you call it, but if you take a piece of wire and 
feed it some distance from the end you now have an off-center fed dipole 
... an extreme version possibly, but an off-center fed dipole nonetheless.

In my opinion, the term "counterpoise" is mostly a silly obfuscation.

	static on FM as usual
Message-ID: <CA+W3KhHbTVmNoN3iLbGt6Bou57SGM8rDj8g7MVDOh0RAm+42YA@mail.gmail.com>

Hi,

I have no idea what is going on, but I probably simply misconfigured
something. I have a KX3/PX3/KXPA100, and I was using it happily yesterday.
Earlier today, I disconnected it to measure for my pelican case, but
reconnected everything and double checked the connections as I always do.
Everything powers up normally including the amp with the special cable, but
there is COMPLETE silence on SSB and CW modes, and just static on FM as
usual.. Turned the radio back off and on, nothing. Upgraded the firmware,
no change. A setting was probably changed last time I used it, but I can't,
for the life of me, figure out which. The sidetone is nice and loud on CW,
but tuning up and down on CW or SSB produces nothing but silence, no
headphone or speaker output at all.

I'd appreciate it if you good folks could help me out.....need to get back
on the air!!!!

Thanks!

Mark KD8EDC

You are both perpetuating the confusion here by pretending that these 
are two different forms of antenna.

Of course the "counterpoise" will radiate.? It will radiate energy 
proportional to the current in it, and the longer its length the higher 
the current will be.? That's EXACTLY the same case as for an off-center 
fed antenna ... they are the same thing.? If you drop the end of an 
off-center fed dipole too close to the ground it will waste energy in 
the form of ground losses as well.

Calling it a counterpoise is a misnomer.

And, of course, as soon as I sent out an email, I figured out that the
OFS/VFO B knob had been spun WAY out of whack and the RIT/XIT offset was
way off. Cleared it out and all is well.

Hello Mark,

Just a guess, but could your RF Gain have been inadvertently reduced
significantly? That could render CW, SSB and AM inaudible while still
allowing FM hiss, assuming it was not being otherwise squelched.

AAARRRGGGGHH, my eyeballs are starting to bleed.

Can we just end this endless thread by saying that #1, you get what you pay
for and 
#2, different strokes for different folks.

If not, why not ANOTHER round of what mike to use ???
Or, what antenna works best???
Or, what grass seed works best under a dipole antenna????

And, of course, as soon as I sent out an email, I figured out that the OFS/VFO B knob had been spun WAY out of whack and the RIT/XIT offset was way off. Cleared it out and all is well.

Thanks, sorry to take up bandwidth.....

Message-ID: <CAOoYq88mcLRUMTE6bbz47G-Gu96hACqs4cy1wxhxYU+cBv-kYA@mail.gmail.com>

I am getting my K3S set up for contesting.  So far I have N1MM+ sending CW
through the USB control.

My question is for setting up voice contesting.  I do not have the K3
digital voice option yet but I can see that N1MM+ does interface with the
K3S audio codecs.

Is there a way to use the N1MM+ software to send audio files over the air,
or to use the K3S to record audio files to be saved and sent later?

Chuck,

Record your audio files as .WAV files. There is extensive documentation on
the N1MM Logger+ Web site, in the documentation section, on where to place
the audio files in the N1MM Logger+ directories, how to edit the
configuration file for its voice keyer function, and how to configure the
logger and the K3S so they all work properly. I had my K3 set up per these
instructions for a couple of years,and it worked very well. Then, last
year, I finally got the K3DVR board.

Good luck!

73 de,

Ian, KM4IK

"?Isn't Semantics fun??"

True.? ;)

Well, I rarely get hung up on the terms people use as long as we all 
know what we mean when we call it whatever we are calling it.? My 
problem with the term "counterpoise" as applied to an EFHW antenna is 
that it pretends that the extra length of wire is something other than a 
way to shift the feedpoint toward off-center instead of off-end.? In my 
opinion it's misleading in terms of how the thing actually functions.

The 3.5 ft aren't added.  On the transformer, the low gnd side is where the .05' wire is added.  It takes care of static and stray capacitance.  I cannot remember the fellow who has written volumes about EFHW's and there is clearly a need for this.  Absent a ground this works extremely well for portable end feds.  The research was done in the field not on a model.  There appears to be some misunderstanding, Dave. EFHW's use a wound transformer to match/reduce the impedance seen on the end of the wire.  I had written about this in a previous post with very poor sentence structure, using "smart phone".

Subject: Re: [Elecraft] EFHW vs Off-Center Fed Dipole



You can use whatever terms you want, but physically and electrically you are turning the EFHW into an off-center fed dipole when you add the "counterpoise" wire beyond the feedpoint.? If you don't agree with that you are merely adding to the confusion.

If you add 3.5 feet to a half wave 40 meter dipole it already is no longer a true half wave anyway, and you might as well just feed the half wave antenna 3.5 feet from one end.

Don't believe me?? I modeled a half wave 40m dipole at 70 feet in 
EZNEC+.? At 67 feet long and fed at the center the feedpoint impedance
was 66 - j4 ohms.? When I simply moved the feedpoint out to 3.5 feet from one end (keeping the total length at 67 feet) the feedpoint impedance became 1509 - j1202.? I then added 3.5 feet to the antenna (total of 70.5 feet) and fed it 3.5 feet from one end, which in your world would be the EFHW with a 3.5 foot "counterpoise."? The feedpoint impedance changed to 3317 - j3115 ohms.? Which do you think would be easier to match (or easier to understand)??? The 3D radiation pattern was indistinguishable from each other in all three cases, of course.

It doesn't matter what you call it, but if you take a piece of wire and feed it some distance from the end you now have an off-center fed dipole ... an extreme version possibly, but an off-center fed dipole nonetheless.

In my opinion, the term "counterpoise" is mostly a silly obfuscation.

It?s interesting that sometimes a simple thread, usually with a very definitive statement of opinion (long wire antennas) generate an incredible number of differing opinions ( we hams are that way).  Then the topic morphs slightly and as long as Eric is tolerant of such threads covers a lot more topics. In the process, for me anyway,  I learn a lot about things that I had never explored in depth.

Take a look at this link by AA6TB where he describes a counterpoise for 
an EFHW.

http://www.aa5tb.com/efha.html????? (see Figure 5)

At least in his version, which I believe is the "standard" configuration 
for one, the additional 0.05 wavelength wire is indeed added to the 
length of the antenna.? All it has done is move the secondary of the 
transformer away from the end of the wire to get a lower impedance ... 
just as I described below.? I don't understand why this is so difficult 
to grasp.

Unless the counterpoise you are talking about is connected somewhere 
else in the system?? Primary side of the transformer?? Somewhere else?? 
If so I'd like to see a link to a drawing of it and I'd like to have 
somebody explain how it supposedly works because it makes no sense to me 
to put it there.

Otherwise, you are indeed adding length to the antenna on the far side 
of the matching network ... just exactly as if it was an off-center fed 
dipole.

Good Evening,

 ??? It was a beautiful day to take a hike. Sunny, 50 degrees, with 
spiders building webs in hope of catching the early insects. The bracken 
fern has died back to where the contours of the ground are exposed 
allowing me to find footing with little danger. Normally they range from 
3 feet to 7 feet in height hiding any deadfalls and burrows. I was able 
to break a trail to a nearby intermittent stream. Before the forest had 
been clearcut the stream to my south flowed year round. Now it is 
seasonal until well below my elevation. As the forest regrows it becomes 
steady at ever higher elevations. Great place to build a blind to 
monitor the elk who bed nearby. With the fern die off they are walking 
new trails which I follow. Elk are tall enough to find paths where I 
don?t have to duck; our local Black-tailed deer are much shorter. Often 
their trails coincide but when a branch intervenes the elk walk around 
while the deer duck beneath it. I am lazy, I follow the elk path.

 ?? The sun has sent us some ions, the aurora are active over Hudson 
Bay. Once this storm settles down we may have improved propagation. One 
can never tell. But radio is like fishing: if you don?t make a few casts 
you?ll never catch a fish and if you don?t catch a fish at least you 
were out fishing ? can?t beat that.

Please join us tomorrow on:

Subject: [Elecraft] K3 strange behavior
Message-ID: <441E0F27-A0C9-4F00-9F57-8D2874AC4B1A@yahoo.com>

I?ve noticed some strange behavior on my K3: sometimes on CW in the middle of a transmission, the K3 doesn?t switch back to RX mode and the red TX LED stays on - lost a few contacts during today's NA CW QSO party as I had to reset the K3 in the middle of QSOs. Only way to get the receiver going again is to do a power cycle (there may be other ways as well, I don?t know). Also I have had all characters of the LCD display come on and back off again when turning VFO A knob. So if I tune slowly in one direction, the display switches from normal to all characters on and back to normal and so on. So something is definitely wrong here. How do I solve this problem? The K3 does not operate reliably anymore.

Thanks,

Andreas, K6AKW

Have you recently upgraded the Firmware, if so, try reloading previous version.
I had a similar problem which cleared up after going back to previous F-W,

I've posted a review of my field test KPA1500 on eHam:
http://www.eham.net/reviews/detail/13702.

I got sort of carried away with testing the amp and used it in NAQP CW even though that contest is limited to 100W. The amp worked great and gave me a delightful 12dB unfair advantage! So my entry is a checklog but I sure had fun generating it. Apologies to my NCCC friends - it was an inadvertent screw-up. I had really intended to operate within the rules and contribute a few points.

All:


I did some testing with a $75 Rolls MX-28 three channel stereo mixer yesterday.

Here are my thoughts using it to split the audio from my K3 and JRC NRD 525 for SO2R monitoring:


You get what you pay for -

At 100W, there is no RFI evident

At 1500Wm I needed to add a number of #31 mix beads on the Power & audio I/O's to choke out RFI which manifested itself as a hum/buzz on CW and modulated junk on SSB.

The pots @ full CCW are not infinite attenuation

That being said - with the proper RF choking, the little mixer is OK for monitor use, but I would not put it in the airchain.

For my airchain, I use a AirCorp 500 PH Pro Announcer Mike Processor which, as a pro device, has internal RFI mitigation.

Most processors used for broadcast have this LF RFI mitigation so they can be used at a co-located AT tx/studio site.

I would start with any model of Rane or Mackie manufactured AFTER about
1998. That's around the time that both companies acknowledged their Pin
One Problems and corrected them. I'm recommending these companies
because their products don't have this problem. Most other products DO.

Bencher BY2 (chromed) or BY1 (black) are great paddles with best performance

I've had MANY paddles over the years and currently use both an N3ZN ZN-5 and a Begali Expedition; BUT for portable and mobile use, I still use one of several Vibroplex "Code Warrior Junior"...it's cheap and reliable. Shop around for the best price. Bert, N4CW

My two dits on the topic..

For @home station work, I use my Begali Magnetic Classic paddle but for portable work with the KX2 I use my Bencher BY-1.  The Begali is much more than $125 but I could put it in my will for my grandchildren?s use as a paper-weight.

After enjoying JT65 and FT8 with WSJT-X on my Mac connected to my Icom IC-7410 via a SignaLink USB box, my radio world is about to change quite a bit. I too am buying a nice shiny new K3S. Hey, I deserve it. I should have it here and out of the box in the next ten days or so.

I'll be using the USB connector on the back of the K3S and connecting the cable directly to one of my Mac's USB ports, so what I need to know are these things:

1. How should WSJT-X's Preference Panels be set for this?

2. What settings must I have in the K3S menus?

3. How should the Mac's Sound Preferences be set? Any others to set?

4. How is ALC controlled? [This was done with the SignaLink's TX control]

5. How is the audio level for the waterfall controlled? [This was done with the SignaLink's RX control]

Hope you can help.

Cheers!

audio CODEC, it can be treated just like any other soundcard.

I cannot answer about the WSJT-X settings or the Mac because I use a 
Windows computer. Others will likely give you those answers.

All of your questions will be answered in the K3S manual.? It is easy to 
read and easy to set up the radio.

1. There is the list of? Rigs for the Elecraft K3/KX3 in the WSJT Radio 
tab along with; Baud rate 38400, 8 bit, no stop, no handshake.?? PTT is 
CAT.? Mode is Data/Pkt, Split is Rig.??? On the Audio tab, select USB 
Audio CODEC for Input and Output.

2. On K3S for Data Mode; MIC SEL Line in, Line Out NOR at 010, RS232 to 
USB,?? See page 33 to select Data A.

3. Don't use a MAC......can't say.

4.? ALC is controlled internal to the radio.? This does require special 
attention and IS NOT like other radios.? You will set the audio via WSJT 
PWR slider for what appears to be 4 bars ALC and with the 5th bar 
flickering.?? The operating output power is controlled with the PWR 
setting on the K3S and is not controlled by the audio level.

5.? This is handled in the computer.?? Again not a MAC user so can't 
say.?? You can adjust the radio Line Out level if necessary.? See the 
info in the K3S manual.

Having had other radios, you will find the K3S to be far superior in 
performance and ease of operation to other radios.?? You made a very 
smart decision.

 K3s setup for WSJT-X is simple and straight forward.? I will admit I struggledfor a long time before I was advised.? Follow these easy steps for the radioand computer setup and u will have it running in about 10 minutes.

I've posted a review of my field test KPA1500 on eHam:
http://www.eham.net/reviews/detail/13702.

I got sort of carried away with testing the amp and used it in NAQP CW even though that contest is limited to 100W. The amp worked great and gave me a delightful 12dB unfair advantage! So my entry is a checklog but I sure had fun generating it. Apologies to my NCCC friends - it was an inadvertent screw-up. I had really intended to operate within the rules and contribute a few points.

Whew!

 ??? Not all that noisy on either band but deep QSB made life 
interesting.? One moment I give a 539 and they come back with a 229.? 
Hmmm... I need to work on my antennas :(? Once the loggers come in next 
Spring and take out a few large, dead trees I can rearrange my 
antennas.? Until then they will remain in place if weather allows.

 ? On 14050 kHz at 2300z:

NO8V - John - MI

W0CZ - Ken - ND

W8SDG - Marc - MI

AB9V - Mike - IN


 ?? On 7044.50 kHz at 0100z:

W0CZ - Ken - ND

K0DTJ - Brian - CA

K6PJV - Dale - CA

W8OV - Dave - TX


 ?? Except for those folks from California the rest of us are due for a 
week of inclement weather.? Sorry, I should rephrase that: we're all in 
for some heavy weather over the next week.? So, a plan - stick next to 
your wood stove, keep the batteries charged, and stay on the air.? There 
are fish out there!

That'll be to the PTT line to power up the KX3, not the Mic input!?
(Care needed.)

Ser2Net (and similar Linux tools) are very good I find.

It's also possible to use Grig to control a remote radio, via Hamlib on
the PC (or Pi) at the radio.?? Assuming of course, that the
implementation for your radio in Hamlib is complete and (relatively) bug
free.?? I have controlled my TS870 that way from one side of the shack
to the other.?? There does seem to be quite a lot of LAN chatter though
doing that, making it a less than pleasant experience if doing that over
the interweb.

For audio over LAN on Linux, I've settled on a very lightweight tool
"Seren".

??? http://holdenc.altervista.org/seren/

Just take note of what you need to do, to run it on a Pi.

It works *Very* well, can provide excellent audio quality, and is true
point to point, unlike the behemoth bloat of Skype.

(I keep meaning to investigate Seren's text messaging facility, to use
as a simple rig control path too.? It's all open source, but I have too
many "Round Tuits" to shuffle as it is.)

Dave G0WBX.

Subject: [Elecraft] KX3: SMA connector issue
Message-ID: <CAP4v5qyO9ioxDnXmr+JZr8Fg8pNTv_7jsLf=K3QR-8U9ZRkUcA@mail.gmail.com>

This is a somewhat minor issue but it seemed so weird I thought I would ask
anyway.

I have a Diamond dual band vhf/uhf antenna that I bought, it has an SMA
connector, but when seated all the way on the KX3 VHF out, something is
shorting out the signal. I have to back out on the connector a little...and
I am not talking about real tight. Just finger tight onto the kx3 and. ...
no signal.

I checked out the Diamond antenna on my th-d72 ht and that is also SMA and
no problems on that radio. I have looked at the connector on the antenna
and it looks perfectly fine. I also have an SMA-S0239 adapter for another
antenna on 2 meters, and no problems with the SMA adapter on the kx3.
thanks if anyone has some thoughts on it.

Thanks for your reply. Yes, I did upgrade my K3 to the latest firmware. Not sure there were problems before since I bought the K3 used and the first thing I did was upgrading to the latest firmware. How can I downgrade the firmware? The Utility doesn?t seem to give me the option to select a particular firmware version.

Best,

Message-ID: <CABa2V3m+OED321MmsYSgkv4qOoxwA5wopFdYZff_wHKZ=8zuEQ@mail.gmail.com>

Attention Canadian and US licensed amateur radio ops, for your
consideration is K3 #75. This unit was updated with the K3SYNA synthesizer
board, KXV3B I/O pre amp board, and NEOGRIP tuning knob ring. The gold
plated header pin replacement was
completed by Elecraft in Watsonville in June 2017.

Includes KPA3 100 watt PA, KAT3 ATU, KBPF3 Gen Coverage RX Bandpass module
and five roofing filters. 6.0 hz, 2.7 hz, 1.8 hz, 700 hz (Inrad) and 500 hz.

The DSP board upgrade has also been done.

An Elecraft Heil MD2 microphone and stand, KSUB firmware upgrade cable, all
manuals and update documentation are included.

This is a one owner, non-smoking environment transceiver. The unit will be
shipped in a factory box, the one supplied from the upgrade.

But wait, there's more! Also in the package is a P3 (2014) and SVGA board
with all necessary cables, documentation. This will be double boxed for
shipping.

Price $2400 USD, does not include shipping.  Current location is Halifax,
NS.

Please reply off list to burch dot craft at gmail dot com to arrange for
photos and a landline from me to discuss.

PS....I have an LP-Pan and Emu 0200 with all cables and documents as well
for $150 USD for the pair.

Reason for sale, cleaning the shack.

This is one of the downsides of the KPA1500.  Unlike other amps, it feels
like QRP when it's putting out 1.5 KW.

John,

The KPA1500 fans are relatively quiet - they move a lot of air at lower 
fan speeds.
However, the power supply fans put up a bit of noise, so shipment was 
delayed while the fans for the power supply were reworked with larger 
fans to keep it quiet.

I have only heard the fans while visiting the Elecraft lab, so take the 
information provided by K6XI's eham review as a better authority than my 
comments.

Belden has many variations for mic cable.

is a quick list I found. We used something like Belden 8428 for

The ship date was moved again to late January to the first of February after
Wayne decided the fans on the RF deck needed to be reworked the same way as
the fans on the power supply.

This is a VERY old (and very outdated) of mic cables, mics, and their 
impedance.? The more important description for the cable is single 
conductor shielded or twisted pair shielded. In the old days, mics that 
used a single shielded conductor WERE high Z mics, and worked into high 
Z input circuits. Think guitar amps. Most modern mics are either 
electret condenser mics or dynamic mics, the vast majority are low 
impedance (150-250 ohms), and are designed to work into a load at least 
5x their own output Z. Good engineering practice is for audio input Z to 
be at least 10x the Z of the source.

Audio cables are NOT transmission lines, they are FAR, FAR, FAR too short.

Virtually NO practical cables have an Zo greater than about 110 ohms. 
Shielded twisted pair cables designed for digital audio are nominally 
110 ohms. Shielded twisted pair designed for analog audio have Zo in the 
range of 70 ohms.? Zo matters ONLY for digital audio, which has 
broadband components.

> Does that matter?
No.

> What gauge wire should I use for a 5ft cable?

Cable gauge matters only for physical strength. Audio cables are 
typically #24 - #26.

Many years ago, I found a partial spool of miniature Belden coax at a 
ham flea market. I use it for unbalanced (single conductor plus shield) 
audio patch cables. It's small enough to fit into virtually any 
connector you're likely to want to use and more robust than most 
alternatives.

There's nothing wrong with using shielded twisted pair for unbalanced 
mics. Simply tie one conductor to the shield at both ends.

I guess we should be glad he insists on getting it right before shipping. I will content my self with the 500 for now. It really does all I need done anyway, just would like the extra power since I downsized from the Collins S line with the 30S1.

In my experience, the best microphone cable stock currently existing is Canare Star Quad cable.
I'm on my phone, so don't want tp peck out a complete answer here and now.
Star Quad cable has 2 twisted pairs and a shield and is nice and flexible broadcast quality cable stock.? Has great endurance.
I use it for my microphone, key, and any other cables I can.? There are at least 2 sizes now....? Get the largest wire gauge available.? Consider putting some on your shelf for future use too.
I use a condenser mic so my wiring may be different, but I would never use the shield as a signal wire if I wasn't forced to....? Use the twisted pairs to your advantage.
Can't help on the multi-pin connectors, as I don't use it at all.? But find and use the best ones tou can find.

John,

For microphone wire and 8 pin plugs, check out Universal Radio 
https://www.universal-radio.com
I have used the ultra flexible Heilwire (universal Radio #2645) and find 
it quite suitable with its shielded twisted pair, and they have 8 pin 
plugs their p/n #2112 that are quite satisfactory.

Thanks to everyone for the quick responses and product suggestions. When
bought a MicroHAM Micro2R years ago to replace a Top Ten DXDoubler I used
the old Top Ten cables. For years I had rotator controller noised getting
into my headphones and I recently noticed that the headphone cables were
not shielded. I stared over making new cables using better headphone wires
and the rotator ramp noise is now completely gone. My next step is to add
mic cables to this device and I wanted to do it properly. K9YC's detailed
explanation was exactly what I was looking for.  I was not sure use if I
should I should buy one or two conductors and if two what to do with the
shield. This morning I purchased a 2 wire Belden mic cable and I will
probably buy the Foster connector that W3FPR listed. Also thanks to K4TAX
and KY5G for their excellent suggestions.

I saw the Heil connectors and Heil wire when I first started my search. I
was not interest in the wire. I did have an interest in the Foster
connectors but could not find them in stock anywhere.

Silicon is great, doesn?t melt if you drop hot solder on it.

John,

I agree that the Heil 8 pin connectors are the best.
The Heilwire is IMHO the best wire for ham applications because it 
contains additional conductors for PTT as well as a shielded twisted 
pair and is soft and flexible.

The nature of the shield matters a lot. Back in 1994, Neil Muncy, 
ex-W3WJE (SK), published the landmark AES paper in which he exposed both 
The Pin One Problem and Shield Current Induced Noise (SCIN). The Pin One 
Problem is the (now) well known equipment design defect, whereby the 
cable shield fails to contact the shielding enclosure, first going to 
the circuit board, where shield current is coupled to the circuitry.? 
SCIN is a defect in the construction of "rack cable" having a foil/drain 
shield, whereby the drain wire is twisted at the same rate as the signal 
pair and is much closer (along the cable) to one signal conductor than 
the other. This causes shield current to induce a differential voltage 
on the signal pair.

Neil did his work on how these mechanisms coupled at audio frequencies, 
but in multiple bar conversations when we met at conventions, he said 
that both were also very strong causes of RFI, and that Pin One was the 
dominant cause. In 2003, I did research that confirmed this. Audio 
old-timers may recall that in the late '80s and early '90s, Mackie 
mixers were almost certain to pick up AM broadcast stations that were on 
the high end of the band. My work on susceptibility of equipment showed 
that they suffered both from Pin One Problems AND that the bandwidth of 
their audio circuitry extended past 1 MHz!? In attempting to use one of 
these mixers to test condenser mics for RFI from FM and TV broadcast, I 
found that these mixers themselves strongly detected RF from TV channel 
2, and were thus unusable!

I also tested the RF rejection of quad cables, including Canare, and 
found that they were inferior in that regard to a good braid-shielded 
cable like Belden 8412. Gotham Audio cable (an EU cable then imported by 
the Neumann distributor) also performed quite well.

All of that work was published as AES papers. You can buy them for $10 
each at aes.org, or you can download them without the AES logo from my 
website for free. :)? k9yc.com/publish.htm? Scroll down to find the AES 
papers.

As to the Heil cable -- I've never seen it, don't know its construction. 
As Don notes, additional conductors can be useful for control functions.

Canare Star Quad does have a braided shield... <confused>
Never did any head to head testing, but I've used it for both balanced and unbalanced runs, and it's always performed flawlessly for me.
Ease of handling, flexibility, and durability gets high marks from me too.
Granted, I am probably a bit biased due to my heavy use of Canare materials in my ouw whole house project and several other distribution setups.? Love their F and BNC connectors and tools, too.

Jim:

Still on topic any tying into a query the other day on the Reflector....

You are are the RFI mitigation guru - I am very impressed with the wealth of test data (especially on ferrite characteristics) that you have amassed. I have this cheap little Rolls MX28 mixer that I am using for SO2R monitoring.  I brute force added about a pound of RG-8 size #31 beads to the AF and power inputs (it worked) but I want to fine tune the scheme.  I have planned (using your data) to make chokes by wrapping the beads with 6 turns of RG-174 (used for audio) and grounding the "output" where it enters the mixer and leaving the input floating for CMRR.  The mixer's impedance is 10K (resistive - no xfmr) bridging.

Thanks, Russ KD4JO

The nature of the shield matters a lot. Back in 1994, Neil Muncy, ex-W3WJE (SK), published the landmark AES paper in which he exposed both The Pin One Problem and Shield Current Induced Noise (SCIN). The Pin One Problem is the (now) well known equipment design defect, whereby the cable shield fails to contact the shielding enclosure, first going to the circuit board, where shield current is coupled to the circuitry. SCIN is a defect in the construction of "rack cable" having a foil/drain shield, whereby the drain wire is twisted at the same rate as the signal pair and is much closer (along the cable) to one signal conductor than the other. This causes shield current to induce a differential voltage on the signal pair.

Neil did his work on how these mechanisms coupled at audio frequencies, but in multiple bar conversations when we met at conventions, he said that both were also very strong causes of RFI, and that Pin One was the dominant cause. In 2003, I did research that confirmed this. Audio old-timers may recall that in the late '80s and early '90s, Mackie mixers were almost certain to pick up AM broadcast stations that were on the high end of the band. My work on susceptibility of equipment showed that they suffered both from Pin One Problems AND that the bandwidth of their audio circuitry extended past 1 MHz!? In attempting to use one of these mixers to test condenser mics for RFI from FM and TV broadcast, I found that these mixers themselves strongly detected RF from TV channel 2, and were thus unusable!

I also tested the RF rejection of quad cables, including Canare, and found that they were inferior in that regard to a good braid-shielded cable like Belden 8412. Gotham Audio cable (an EU cable then imported by the Neumann distributor) also performed quite well.

All of that work was published as AES papers. You can buy them for $10 each at aes.org, or you can download them without the AES logo from my website for free. :)? k9yc.com/publish.htm? Scroll down to find the AES papers.

As to the Heil cable -- I've never seen it, don't know its construction. 
As Don notes, additional conductors can be useful for control functions.

I've used some star quad cable in certain pro audio applications. 

The braid shield type is necessary where flexibility is required however, just as in coax, not all braid is the same.  Some provides 85% shield (poor) while others approach near 100% shielding (good).   There is a difference in price, usually for this reason.

I looked at your paper "Common-Mode to Differential-Mode Conversion in
Shielded Twisted-Pair Cables (Shield-Current-Induced Noise)" The cables are
not identified by name. Is there a cross reference you can provide?

I try to use double shielded cables or hardline in my RF installations. I
have seen leakage on the order of -40 dB on crappy cables.

I did use a knockoff Star Quad cable for my microphones but have no data to
substantiate using it. Reading your info, it may not be the best choice. I
had to add a braid from the mixer chassis to the microphone mounting for a
good ground to eliminate my RFI problems. Connecting the braid to the shock
mount inner ring did not work. The Metal shock mount inner ring was not
connected to the metal microphone body! It looked connected, but must have
a painted plastic part or non conductive paint.

Thanks for all the info,

Mark

Hi Bob,

Shield coverage does not matter!? Study the SCIN paper -- what matters 
is the UNIFORMITY of the shield. In the world of pro audio, we learned 
long ago that twisting is at least as important as shielding, both at 
audio and RF frequencies. From the earliest days of telephony, telco 
cables ran on the same poles as power. In those days, power was 
relatively free of AF noise components. The only noise rejection 
employed was that the telco pairs were crossed over every few poles. 
This was sufficient because of the long wavelength of 60 Hz and the low 
harmonics associated with running motors.

At an RFI workshop I taught in 2005 with other members of the AES 
Standards Committee WG on RFI, I demonstrated the use of one pair of a 
CAT5 cable carrying mic audio from a pro condenser mic to the audio 
mixer with both conductors of another pair connecting the Pin 1s. That 
connection provided a bond for the mic shielding and a path for phantom 
power needed to power the mic. I injected RF along the cable using a 
Nextel phone and a TH-F6A Kenwood talkie, moving both along the cable, 
and keying the talkie on-off continuously to generate AM. Another of the 
same mic type was connected to the same mixer via Belden 8412. The mics 
had some RFI susceptibility at VHF and UHF. The two cables were equally 
good at rejecting the RFI.? In his workshops, Neil Muncy demonstrated 
the value of twisting by running a very long chain of mic cables around 
the facility where he was presenting it, then moving a tape demagnetizer 
along the line. The only hum heard was where the twist was interrupted 
at mated XL connectors.

Someone asked about cross-references to the cable types tested. The 
foil/drain cables included everything I could get my hands on at the 
time. The braid-shielded cables included a variety of what was in my 
working stash, a few samples that Belden provided, and a nice selection 
from Gepco. Based on my work, Gepco later produced a miniature 
braid-shielded twisted pair with no drain wire (comparable in size to 
standard rack cable and mic snake pairs). The braid/foil pair came from 
a member of the SynAudCon pro audio community working in Brazil. Based 
on Neil's work, he got a local cable company to build it for him.

In general, all you need to know is to avoid foil/drain cables, if the 
cable is shielded, it should have a braid shield with no drain wire, and 
that a twisted pair cable with a drain wire is worse than no shield at all.

30 years ago, when I was living in Fairfax County, VA, the TV cable was

in need of the proper name for that cable, so I can search some out.

I used it as feed for a full size lazy 80 meter loop - about the same as

I've seen the name "TwinAx" somewhere.  It was probably networking or 
terminals, at least 30 years ago.

Twinax under that name was a two conductor shielded coax like cable for balanced antennas.  The R-389 for instance had a connector for that kind of cable.

But are you sure you are not thnking about the cable for Token-Ring networks?  That was two pair for IBM networks of about 25 years ago.  Stiff and ugly to work with.

Subject: [Elecraft] KX3/PX3/KXPA100 + accessories for sale
Message-ID: <CAGxZ45qiL-jRjK403gbN8C+ju9s2dpg_2zK7T_Vx+H97nx54vQ@mail.gmail.com>

Hi,

I have a KX3/PX3/KXPA100 combination I'd like to sell. I am the original
owner, and purchased all of the above in 8/2014. The KX3/PX3 was purchased
factory assembled, the KXPA100 was purchased as a kit, and assembled by me.
The KX3 is fully loaded, as you will see below, to include the 2m option.

All of the equipment is in excellent condition, and the PX3/KX3 have the
Side-KX options installed, including the plastic covers. The covers are in
good shape, with minor scratching as to be expected from plastic covers.
Photos are included below, with covers off/on.

In the interest of full disclosure, while performing the suggested
capacitor modification to improve the power-on delay on the PX3 (as guided
by Elecraft) a solder pad pulled up. This was repaired with a solder bridge
to the new capacitor in question, and the unit has functioned perfectly
since this time (April 2017). I am adjusting the requested price
accordingly, even though there is no impact to the performance or
functionality of this unit (and the power on delay is significantly
improved!)

I have included a video in the link below so you can see the
PX3/KX3/KXPA100 functioning. The cursor will skip ahead if you move it
quickly, but it's always done that since new, and as far as I can tell is
common to PX3s in general (my friend's does the same). I made sure to
include this in the video (you'll see it happen at one point) - the cursor
will move faster than I rotate the knob. I also adjust ref/scale and move
around the band both via radio and via PX3 in the video, so you can see it
is functioning as expected.

Everything else is exactly as delivered from Elecraft, and functioning
properly. The KX3 has had the full set of calibration performed on it, to
include extended temperature compensation, nulling, and filters, as I have
a bench of test equipment including a GPSDO locked signal generator.

Here's what I'm including, and current list pricing:

MH3 Hand Mic. for KX3
$59.95

KXFL3 Dual-Passband Roofing Filter
$149.95

KXAT3 ATU for the KX3
$199.95

KXPD3 Precision Keyer Paddle
$129.95

KXBC3 Int. NiMH Charger/Clk for KX3
$79.95

KX3-2M-AT 2M All-Mode Internal KX3 Option
$259.95

KXPACBL KX3 to KXPA100 Adapt. Cable
$49.95

KXPA100-K 100 W External Amplifier - Kit
$749.95

KXAT100 Internal ATU for KXPA100
$379.95

KX3-F 160-6 M Xcvrr Assm
$1,049.95

PX3-F Panadapter for KX3 - Factory Assembled
$599.95

XG50 Simple 49.380 MHz Signal Source
$39.95

SUBTOTAL $3,749.40

Keep in mind this subtotal does not include the Side-KX sides/covers. I am
also including the original sides for PX3/KX3 in case you wish to use them
instead. I do have the upgrade board for the paddle, as well, as well as
various tools/parts for the accessories. I am also including a few KXUSB
cables which currently list for $32.95. I'll also throw in the 2m antenna
seen attached to the radio in the photos.

KX3 serial number is 6755, PX3 is 0630, and KXPA100 is 1218.

-------------------

I'm willing to sell the whole package for $2800 OBO.

My reason for selling is simple, I'm moving up to a pure desktop
(configuring a K3s as we speak) setup as I've not found myself working
remote as I had anticipated.

https://photos.app.goo.gl/g6rqVoXqF8i1FnL63 has photos and the video
showing operation, taken today (Jan. 16, 2018).

I live in San Antonio, TX and would prefer to arrange for local (you can
check it out in person) or regional pickup (happy to meet half-way) via
cash, but check/money order can be negotiated for remote buyers as well (US
buyers only, need to wait for check to clear/MO to be validated - been
burned before which is why I prefer local sales). I have batteries, so if
meeting elsewhere, we can turn it all on so you can verify operation if
desired.

My call-sign is K5DJO, name is David Orman, please respond directly to my
email ( ormandj at corenode.com ) and I'll pass you the rest of my contact
information so we can discuss via phone if you'd like! My address and
information is current in FCC/ULS, and I can provide additional
photos/videos if requested.

Respectfully,
David Orman / K5DJO

I am NOT looking for TwinAX nor two coaxes wither their jackets bonded. 
RG400 is what I'm looking for, and thanks to those who correctly read my

That is a coax with a double shield except the shields are each insulated.

Dual or Siamese coax


73-Gary K9GS?
-------- Original message --------From: Bill <bill at w2blc.net> Date: 1/16/18  1:55 PM  (GMT-06:00) To: elecraft at mailman.qth.net Subject: [Elecraft] Special type of coax - need info 
30 years ago, when I was living in Fairfax County, VA, the TV cable was 
shipped around on a double coax cable. It resembled lamp cord or zip 
cord, and was two parallel coax lines with a webbing between them. I am 
in need of the proper name for that cable, so I can search some out.

I used it as feed for a full size lazy 80 meter loop - about the same as 
tuned feeders would be used. It worked very well on all bands - 
providing lots of DX and a ton of local coverage also. Not a tri-bander 
- but it beat the socks off other wires and verticals. I want to 
duplicate that antenna this spring.

Thanks,

Bill W2BLC K-Line

Thanks to all that replied. I was reminded that the shielding is 
aluminum etc. I had forgotten that little detail over the years.

I do now recall that the cable I used did have copper - it was used 
exclusively at the head-ends and was hard to get.

Hence, I think I will parallel some RG8X, use cable ties and Goop, and 
make my own. That way I can make solid soldered connections for everything.

Gotta do things right the first time and have it last many years with no 
further service.

Thanks for the reminder.

I've had my KPA500 for a couple of weeks, now, and I have questions
relating to its efficiency as a function of power output and band. A friend
of mine recommended that I run only 300 watts output most of the time in
order to preserve the life of the FETs. I told him that I didn't spend
$2300 on an amp just to get less than 5 dB of gain in my signal (over my
100-watt exciter) instead of the 7 or 8 dB I paid for. Am I wrong?

I took a lot of data this morning that indicates that there is an inverse
relationship between output power and efficiency - to the extent that, down
to about 300 watts, I find that the amount of heat the finals have to
dissipate is less, the higher the power output. This is rather
anti-intuitive.

And if that is true, then wouldn't it be better for the finals if I
routinely ran the amp at the higher power, so long as voltage, current, and
temperature remain within safe limits? Is it safe to run 600 watts on CW,
especially on 80 and 160 meters, where the efficiency appears to be so good
that the finals run cool at 600 watts - even cooler than at 500 watts?

The following data was taken while transmitting into a dummy load. I
adjusted the drive power to obtain one of several predefined output power
levels and then measured input volts and amps and calculated input power
(HV x Current), power dissipation (Input - Output), and efficiency
(Input/Output). Each measurement was taken after about one second of key
down in CW mode. Doing the calculations in between each test allowed the
finals and dummy load to cool off. I never heard the fan come on. Drive,
Output, Input and Dissipation are in Watts. I have shown voltages falling
slightly below 60.0 in red, but I had no problem getting 600 watts output
with less than 40 watts of drive, even in those cases.

        27    600    60.6  13.8   836     236         72%

Note that in every case there is lower power dissipation (and therefore
less heat generated), the higher the power. I decided to test several lower
power outputs on 20 meters, and I got the maximum dissipation at 310 watts,
and the dissipation at 225 watts was nearly the same as it was at 400 watts.

I should point out that my HV during standby or idle hovered between 79.5
and 80.0 volts. I am using the Red tap wire on the 115-volt input.

And, yes, I know not to use the amp on 60 or 30 meters.

If anybody is going to yell at me for testing a 500-watt amp at 600 watts ?
and for proposing to use that much power routinely on 80 meter CW ? let me
know your reasoning and why or how you think that would stress the amp.

Oh, and does anybody know if Elecraft would have adjusted the Power
calibration (per band) of the KPA500 kit version, as mentioned in the User
Manau? I found all the settings to be at their default 100%, FWIW. When
comparing at 100 watts to a cheap external watt meter (which agreed with my
TS-590sg power output setting), I found I had to increase power on almost
every band to 104 watts to trip the 100-watt indication on the KPA500's
wattmeters. I decided to leave the settings at their default.

Richard,

 ??? The FET amplifier is adjusted for a given power output. You have no 
PI Net adjustments with the FET amplifier. It is tweaked to have maximum 
efficiency at somewhere near the full rated output. It is all up to the 
designer. What you will see is an increase in efficiency as you slowly 
turn up the drive level. At somewhere near full power, you will get the 
best efficiency. This is normal.? The best advice is to not overdrive 
the amplifier. Also, keep track of heatsink temperature if you will be 
running something like RTTY etc.? Excessive heat is bad.? I think 
running at 600 watts peak is OK as long as you are not dealing with dead 
carriers? as a rule.

Your KPA500 is designed to produce 500 W at the antenna connector and is 
most efficient there.? You can watch the PA temp [or put the fans in 
automatic and listen to them do it for you].? Field testers were 
encouraged to run it at full scale, and they did.

The amplifier was designed for max efficiency at max output.? You seem 
to have proved the Elecraft designer was successful.

Rick,

I think you are trying to "outwit" the designers.
One thing I can say is that the KPA500 is quite robust and 
conservatively rated.  One or more of the Field Testers was asked to run 
an RTTY contest at "full out" power, and I know one who ran the whole 
weekend contest at 700 watts and no problems were detected.

Typical of Elecraft's conservative designs, there are 2 devices, but the 
ratings for each device is equal to the stated power output for the 
amplifier.  Other manufacturers may specify the power for the maximum 
ratings for the devices, but not Elecraft.

The FETs in the KPA500 are *each* rated for greater than 500 watts - 
that is a total of 1000 watts, so they are "loafing along" at 500 watts. 
  Similarly with the KPA1500 which uses 2 devices each rated at 1500 
watts (3000 watt rating total), the KPA1500 will do legal limit with the 
devices loafing along.

Bottom line, the Elecraft amplifiers will do maximum power at a 50% duty 
cycle all day long.  You should reduce the power for long winded AM 
transmissions, but otherwise you can run maximum power.

As far as the efficiency, that is a design compromise.  Maximum 
efficiency is achieved at somewhere near the maximum rated output.  At 
levels less than the rated power (or greater than), you can expect the 
efficiency to decrease.

Even below the rated power, the devices are running well below their 
rated levels, so you are not stressing the FETs by running below 500 watts.

In other words, the designer will set the parameters for the maximum 
power rating, and above and below that point, the efficiency will be 
lower because the optimal impedance will not be present.

Message-ID: <1516146822.161942.1237806448.17FD88CA@webmail.messagingengine.com>

I was experiencing broadband noise on the spectrum generated from my RX I/Q port when the KX 3 ACC port was connected via USB to my laptop.  I tried grounding, different USB adapters and cables, and ferrite toroids without any success.  All the gear is powered by battery. 

I suspected a ground loop as the noise was uniformly distributed around the tuned frequency.  I ordered an Adafruit part number 2107 USB Isolator for $35 from Adafruit.com.  This board isolates both the power and data on the USB connection to eliminate ground loop problems which can plague USB test equipment as well as ham gear.   Plugging it between the laptop and the ACC port USB cable removed the noise completely.

First, let me assure you that with 19 years experience working with Elecraft, running (and sometimes abusing) their gear while writing many of the Elecraft manuals, they ALWAYS use very conservative designs. There is no reason whatsoever to run less than 500 watts with the KPA500 in terms of operating life of the FETs or anything else in the amplifier. 

With respect to your measurements, I've not done them on my KPA500 but note that the output filters are designed for maximum efficiency at the full rated power. As you change power output, you change the output impedance of the finals so it is no longer optimum for the output filters so the finals will not be as efficient at the lower power levels. That's usually of no consequence because the total heat generated by the finals will always be well within their normal operating specifications. 

Of course it IS significant if you are looking to get the highest possible overall efficiency out of the KPA500, as your measurements indicate.

Subject: [Elecraft] KPA500 Questions about power and efficiency

I've had my KPA500 for a couple of weeks, now, and I have questions relating to its efficiency as a function of power output and band. A friend of mine recommended that I run only 300 watts output most of the time in order to preserve the life of the FETs. I told him that I didn't spend
$2300 on an amp just to get less than 5 dB of gain in my signal (over my 100-watt exciter) instead of the 7 or 8 dB I paid for. Am I wrong?

I took a lot of data this morning that indicates that there is an inverse relationship between output power and efficiency - to the extent that, down to about 300 watts, I find that the amount of heat the finals have to dissipate is less, the higher the power output. This is rather anti-intuitive.

And if that is true, then wouldn't it be better for the finals if I routinely ran the amp at the higher power, so long as voltage, current, and temperature remain within safe limits? Is it safe to run 600 watts on CW, especially on 80 and 160 meters, where the efficiency appears to be so good that the finals run cool at 600 watts - even cooler than at 500 watts?

The following data was taken while transmitting into a dummy load. I adjusted the drive power to obtain one of several predefined output power levels and then measured input volts and amps and calculated input power (HV x Current), power dissipation (Input - Output), and efficiency (Input/Output). Each measurement was taken after about one second of key down in CW mode. Doing the calculations in between each test allowed the finals and dummy load to cool off. I never heard the fan come on. Drive, Output, Input and Dissipation are in Watts. I have shown voltages falling slightly below 60.0 in red, but I had no problem getting 600 watts output with less than 40 watts of drive, even in those cases.

        35    600    59.8  15.2   909     309         66%

 24     23    500    61.4  12.4   761     261         66%
        30    600    61.0  13.5   824     224         73%

 28     22    500    61.4  12.7   780     280         64%
        27    600    60.6  13.8   836     236         72%

Note that in every case there is lower power dissipation (and therefore less heat generated), the higher the power. I decided to test several lower power outputs on 20 meters, and I got the maximum dissipation at 310 watts, and the dissipation at 225 watts was nearly the same as it was at 400 watts.

I should point out that my HV during standby or idle hovered between 79.5 and 80.0 volts. I am using the Red tap wire on the 115-volt input.

And, yes, I know not to use the amp on 60 or 30 meters.

If anybody is going to yell at me for testing a 500-watt amp at 600 watts ? and for proposing to use that much power routinely on 80 meter CW ? let me know your reasoning and why or how you think that would stress the amp.

Oh, and does anybody know if Elecraft would have adjusted the Power calibration (per band) of the KPA500 kit version, as mentioned in the User Manau? I found all the settings to be at their default 100%, FWIW. When comparing at 100 watts to a cheap external watt meter (which agreed with my TS-590sg power output setting), I found I had to increase power on almost every band to 104 watts to trip the 100-watt indication on the KPA500's wattmeters. I decided to leave the settings at their default.

Hey Richard;

I?m glad you are enjoying our creation. The KPA500 is truly a fine piece of hardware and firmware
that continues to evolve. The most recent firmware version is V1.54, releasing in mid December.

Others have answered many of your questions, let me give my shot at a few. I usually run my
KPA500 in contests at 600 watts. Briefly lighting the 700 watt LED is not unusual, but I don?t
consistently leave it lit. The amplifier is quite comfortable at 600 watts for long periods of time.
Mine is one of the first units and was hand-built, so I can?t claim to have the original PA Deck
installed (it is still sitting on my work bench however), but my current PA Deck is one of the
original shipping versions. After about 10 years, it is working just fine for me.

As for calibration, we perform the cal at the factory for factory-built units, but not for kits.
The reason is that we need to marry the front panel board with the PA Deck to perform these
adjustments, something that is not done until well into assembly. The adjustment values are
kept in memory on the front panel board?s processor. This also means that if you swap the
PA Deck you will need to recalibrate the measurements. Feel free to perform your own
calibration to a known standard. You will probably find that you will need to vary the values
by some small amount to get really accurate measurements. In general they are pretty close
to start off with, but won?t be ?right on.?

Enjoy the amplifier, and by all means use it at the power you want. If you have any questions
or need any help, we are here, just ask. You will find customer support to be very helpful.

73!

I did it again.  I meant to send this to the group but sent it to Jack
direct.  Sorry Jack.

"The most recent firmware version is V1.54, releasing in mid December."

I went to the software page and it says the most recent beta release is MCU
1.52 Nov 17, 2017 and production release is 1.47.

Well shoot, I'v been using mine at 300 watts to save the finals, no more. I've been driving it with 18 watts out of the K3. What drive power do you recommend? I use it on both CW & SSB. Don't run digital and use my Collins 32V1 and 75A4 on AM.

Hey Richard;

I?m glad you are enjoying our creation. The KPA500 is truly a fine piece of hardware and firmware
that continues to evolve. The most recent firmware version is V1.54, releasing in mid December.

Others have answered many of your questions, let me give my shot at a few. I usually run my
KPA500 in contests at 600 watts. Briefly lighting the 700 watt LED is not unusual, but I don?t
consistently leave it lit. The amplifier is quite comfortable at 600 watts for long periods of time.
Mine is one of the first units and was hand-built, so I can?t claim to have the original PA Deck
installed (it is still sitting on my work bench however), but my current PA Deck is one of the
original shipping versions. After about 10 years, it is working just fine for me.

As for calibration, we perform the cal at the factory for factory-built units, but not for kits.
The reason is that we need to marry the front panel board with the PA Deck to perform these
adjustments, something that is not done until well into assembly. The adjustment values are
kept in memory on the front panel board?s processor. This also means that if you swap the
PA Deck you will need to recalibrate the measurements. Feel free to perform your own
calibration to a known standard. You will probably find that you will need to vary the values
by some small amount to get really accurate measurements. In general they are pretty close
to start off with, but won?t be ?right on.?

Enjoy the amplifier, and by all means use it at the power you want. If you have any questions
or need any help, we are here, just ask. You will find customer support to be very helpful.

73!

Someone please help me out because I can't find the answer.

K3s and KPA500 - I know there is a setting so the K3 will know the amp 
is in OPER state and automatically reduce the drive to 25 or so watts. 
Then when you put the amp in STBY of OFF, the K3 will go to 100 watts.

My Amp and K3 are talking to each other for band changes etc but I can't 
get the power to automatically reduce as described.

What am I missing?  Point me to the page in the manual

Using the KPA Utility I just upgraded mine from 1.47 to 1.54, so it is 
there.

But I agree, the Elecraft site does not show 1.54 as being available.

I think you have to set the power to required setting in Operate mode the first time. The radio will reset to full or low when amp Mode is selected after that.

Back in my broadcast years I worked at the low budget end of the industry where we did what ever it took to get on the air at the lowest cost possible. In  small market stations where Radio Shack was our primary local parts supplier we abused unbalanced lines to the extreme as long as the cable length was not too long and the nearest transmitter was not too close. Low cost mixers had 3 pin connectors but with two pins grounded to accommodate a broad range of low cost mics, cables and adaptors. 

Later in life when I had more money, the cost of mixers, differential amps etc was lower and the distance to high powered amateur radio transmitters was inches rather than miles, I adopted a more rigid adherence to broadcast standard low impedance cables even over relatively short cable lengths of a few inches or feet. As good as the noise rejection of new pre-amplifiers are, I still find separation of shield grounding and the minus side of a mic input important with modern radios. This has become more important in the era of huge numbers RFI sources such as digital radios, local residential RFI from IOT, LED lamps, cheap switching power supplies, thermostats and people still using compact fluorescent lights. 

OK honest truth, how many of us only have one radio operating at a time? How often do you need your HF rig to reject RFI from your VHF/UHF transmitter, computer accessories or switching power supplies in our energy saving appliances.

I may be showing my age but physics doesn't change. Shielding external noise before it reaches the input to the pre-amplifier is still an effective strategy. I still use balanced lines when ever I can.

The nature of the shield matters a lot. Back in 1994, Neil Muncy, ex-W3WJE (SK), published the landmark AES paper in which he exposed both The Pin One Problem and Shield Current Induced Noise (SCIN). The Pin One Problem is the (now) well known equipment design defect, whereby the cable shield fails to contact the shielding enclosure, first going to the circuit board, where shield current is coupled to the circuitry. SCIN is a defect in the construction of "rack cable" having a foil/drain shield, whereby the drain wire is twisted at the same rate as the signal pair and is much closer (along the cable) to one signal conductor than the other. This causes shield current to induce a differential voltage on the signal pair.

Neil did his work on how these mechanisms coupled at audio frequencies, but in multiple bar conversations when we met at conventions, he said that both were also very strong causes of RFI, and that Pin One was the dominant cause. In 2003, I did research that confirmed this. Audio old-timers may recall that in the late '80s and early '90s, Mackie mixers were almost certain to pick up AM broadcast stations that were on the high end of the band. My work on susceptibility of equipment showed that they suffered both from Pin One Problems AND that the bandwidth of their audio circuitry extended past 1 MHz!  In attempting to use one of these mixers to test condenser mics for RFI from FM and TV broadcast, I found that these mixers themselves strongly detected RF from TV channel 2, and were thus unusable!

I also tested the RF rejection of quad cables, including Canare, and found that they were inferior in that regard to a good braid-shielded cable like Belden 8412. Gotham Audio cable (an EU cable then imported by the Neumann distributor) also performed quite well.

All of that work was published as AES papers. You can buy them for $10 each at aes.org, or you can download them without the AES logo from my website for free. :)  k9yc.com/publish.htm  Scroll down to find the AES papers.

As to the Heil cable -- I've never seen it, don't know its construction. 
As Don notes, additional conductors can be useful for control functions.

Hi Garry,

As a genuine OF (born 1941) who still keeps trying to learn something 
new every day, I strongly suggest that you study the material on my 
website about The Pin One Problem. I own thousands of feet of high 
quality pro mic cables and about 40 pro mics. Yes, physics doesn't 
change, but some of what we have learned about it over the years is 
simply wrong.

If all of the gear in a station is properly bonded, everything in your 
home is properly bonded, including power, and all of that is properly 
bonded to your station, and if the input gains and output levels are 
reasonably well set, and if all cable shields are bonded to the chassis 
at the point of entry, and if all power for station equipment comes from 
outlets that either share the same green wire back to the panel or from 
outlets that have their green wires bonded together, there is no need 
for anything fancy in the way of cable, nor is there any need for 
balanced wiring.

There are two tutorials on power, grounding, and bonding on my website. 
One, written for installers and contractors for large and small? audio 
and video systems, was commissioned. You'll find it listed as a "white 
paper for the real world." The other is in the form of slides for a talk 
that I've been invited to give at ham events and to ham clubs on power, 
grounding, bonding, and audio interfacing for hams. k9yc.com/publish.htm

If I were in the position of defining standards for consumer audio and 
ham radio back in the '60s and '70s when the transformation began 
between hollow state and solid state gear, I would certainly have gone 
for balanced interfaces (i.e., shielded twisted pair). But that didn't 
happen, and we're stuck with unbalanced interfaces. The simple, solid 
engineering outlined in those slides is an inexpensive and dependable 
solution.

If you're running AM, 500W PEP is what you get with 125W carrier and
100% modulation. Run over 125W carrier and you will flat top and
splatter. (In theory. I don't use AM so haven't tried it.)

Thanks for comment Alan,

we still have some of them as we had to purchase large role of that material
in order to get nice price from the seller.
So we cut them for these mats and completed the set which they are fit to
labs as same as to kitchen :)
Some of these set are still available in radioclub.

After ordering and arrival I decided to make several tests:

Several oils, greases and different solvents and mat survived without
any damages.

The flare-up point and it seems to be higher than 1000 C which is
corresponding to almost 2000 F. (I was limited by temp sensors and
thermometer
over here)

The burning thru temperature and it survived 450 C for 2mins which is
corresponding to 850 F. (I was limited by my soldering station, hi)

The max of the temp without any noticeable damage of the top layer. It
survived 200 C for 2mins which is corresponding to 400 F.

Best regards,
73 - Petr, OK1RP

Petr,

I don't understand why some sellers insist on CONUS only.  I can 
understand if they do not want to fill out the customs forms, but that 
is not difficult.  The amount of insurance can be limited depending on 
which country the item is being shipped to, and that can be a factor for 
high value items.

Of course, many sellers do not seem to realize that shipping to Alaska, 
Hawaii, and Puerto Rico is the same as shipping to the continental US 
and so they specify "CONUS" when it is not necessary.

The other possibility is that they do not want to deal with payment from 
all over the world, but PayPal makes that seemless in most cases.

The only environmental issues that could affect audio are 1) magnetic 
fields developed by faults in the power wiring in your home or leakage 
flux from big power transformers; 2) a variable-speed motor controller 
very nearby; 3) difference in potential between interconnected equipment 
that creates leakage currents on cable shields.

Cable shields have NO effect on magnetic coupling at audio frequencies. 
Twisting, however, is VERY resistant to magnetic coupling. #2 is by 
magnetic coupling if the source is nearby. The cure for #3 is BONDING.

Magnetic coupling also occurs in loops that are part of the signal path, 
like cable shields in unbalanced circuits. Coupling is proportional to 
the area of the loop, so keeping bonding conductors as short as possible 
helps.? Also, by virtue of the difference in the resistance of cable 
shields and bonding conductors, a beefy #10 or #12 bonding conductor 
will carry far more of any induced current than cable shields that are 
typically #18 - #22 gauge.

Don,

This is one of my biggest gripes.  So many sellers (and not just 
hams) that will not ship to AK/HI or outside the US (48-states).

I handle all international sales of preamps for (Pete-WA2ODO) since 
most want to use PayPal for its ease of currency exchange.  I also 
handle any US sales that want to use PayPal to purchase Pet's 
preamps.  MY point is that I am doing custom's paperwork and the 
differences in insurance for different countries a lot.  The form is 
not difficult:  They want both address of sender and receiver, 
description of package, weight, value of package, and shippers code 
(a drop down menu) which for most will be the under $2500 
category.  If you do the form at the PO they will help 
you.  Insurance coverage differs by country so sipping expensive 
items might not be attractive by international mail.  UPS/FedEx are 
an alternative but an expensive one; typically 2x or more what 
flat-rate priority mail will cost.

Alaska is on the NA continent (not an island floating off Catalina Is

If I'm not mistaken, PayPal payments are revocable -- they can be reversed.

Recovering the item or getting your money is easier if you can do it 
under the same legal system -- if you don't have to deal with 
international law.

Most of us have no desire to commit fraud, so it isn't an issue.

That doesn't explain Alaska or Hawaii, especially if the buyer is 
willing to cover shipping.

I occasionally sell on eBay and I have one simple reason for Conus only.
Packages sent out of the US cannot be insured, at least through USPS, so if
they are lost or damaged you have no recourse.
Maybe that?s not true of private shippers I don?t know.
As far as PayPal protection they almost always side the buyer, not the
seller. I don?t believe they offer any help if your package is lost or
seriously damaged, in fact it?s usually the  opposite, if a buyer gets
something damaged then you as the seller are forced to refund all the
money. So, if it is uninsured because you can?t get insurance if it?s
shipped out of the US, your out the item and have to pay the buyer back.

Tom,

You might want to change your designation from "CONUS" to "United States 
addresses".
CONUS restricts it to the 'lower 48', and does not include Alaska, 
Hawaii, and Puerto Rico.
Shipping to those states and US possessions is no different than 
shipping to your next door neighbor - at least that is true for USPS 
shipments.

Your wrong,? priority mail packages have insurance,? the same flat rate 
price to
Hawaii or any place in the USA.
Plus if you wish insurance you just ask for it and you pay, I pay it all 
the time if
I want extra coverage.
Who in the world told you you cant insure a package in the USA ??
Hawaii and Alaska are USA,? not foreign.
I find many people have no clue that a flat rate priority box is the 
same price for
any weight to any place in the US,? yea Hawaii and Alaska is the US.
Out of the US and CONUS are two different things.

20 Watts.  When the amp is then set to STBY it will revert to full output
of 100 Watts (or whatever you have set it to in that position.)

There already is control software, Rich. KPA1500 Utility, much like the
other Elecraft Kxxx Utility programs, has several pages of support.  I have
been using the Operate page to run my field test KPA1500 remotely and it is
excellent. It displays all relevant operating parameters in numeric form
and allows full control of switchable modes and more. They plan also to
release KPA1500 Remote which, like KPA500 Remote and KAT500 Remote, will do
much the same thing in a more elegant form with bar graphs for power, SWR,
temp, etc. It will also be capable of client/server operation across longer
distances. KPA1500 is the most friendly amp I've used for remote operation,
whether that's across the room or across country.

Since I've had one on order since day one, it would be nice to have a 
copy of the manual (and utility) available for review and preparation.? 
While I am sure it is a very close sibling to my KPA500, it's winter 
doldrums, there will be some differences and the reading would help to 
pass the days of waiting.? ;-)

I just upgraded my K3S's to the latest firmware. It is so easy, I should do
it more often. I have read that there is now a way to adjust the line out
monitor level however I cannot find documentation showing how this is done.
The default level is actually fine however I am curious where the Line Out
settings are.

In the firmware release notes[1] under "K3 MCU 5.58 / DSP 2.88 / FPF
1.26, 3-16-2017":

"* TX LINE OUT (MONITOR) LEVEL NOW ADJUSTABLE: In CONFIG:LIN OUT menu

These are excellent reviews, I especially liked W0YK's comment about
having to consult the wattmeter to confirm that it was running. This would
have been the perfect amp for Ed to bring to Sabana Basora, Aruba for the
2018 RTTY Roundup. Are any stations outside California testing the
KPA-1500?

Subject: [Elecraft] K3s RX Out and IF Out
Message-ID: <F3E4DAD4-FEE1-4D44-B9D0-E42463DAC1C9@mac.com>

My K3s kit should arrive next week and I have not been able to discover the answer to these two questions in either the manual or by studying the schematics.  The purpose of these questions is to help me integrate my current SDR Receiver (SunSDR2 NANO) with the K3s to use as a panadapter.

Also, this is a hardware question relative the k3s only.

1.  When using the K3s in the normal fashion as a transceiver is the signal that is present at the ANT1 or ANT2 (whichever is being used) also available at the RX Out jack?  Is this a viable source of a connection to the RF input of the SDR?

2.  If the SDR is connected to the buffered IF Out jack what will the level of the 8215 kHz IF output be?  Stated either as maximum level, dB above the signal level available at the antenna connector or dBm relative to a -73dBm signal at the selected antenna connector.

This is for the K3.  The K3S has a different preamp setup so the numbers 
should be scaled accordingly.

With the preamp off, the gain from the K3 antenna to the IF output is 
approximately -6 to -7 dB, depending on band and on the particular K3. 
With preamp on, the gain from antenna to IF out is approximately +4 to 
+5 dB.

That assumes it is not an older K3 that has not had the IF output 
modification performed.  In that case, subtract about 10 dB from both 
gain figures.

Message-ID: <r470Ps-10132i-863C439F14854E75948927A23C93D1D4@Williams-MacBook-Pro.local>

JI'm posting just in case someone else has this problem.

I added more bonding to my station and put a lug under the IF In 
BNC connector on the P3 as part of the project. Afterwards, my 
P3 was noticeably deaf. When I started to operate in the North 
American QSO party, I couldn't see any of the stations.

I got out the manual and discovered that there was a switch to 
activate the IF Out connector. I moved the switch to Off and 
everything was good again. I moved it to on, and I only lost 
about 3dB, just like the manual said. Some experimentation 
showed that if the switch was between off and on, the loss was 
much greater, like 15dB or so. I must of pushed the switch when 
I was adding the lug.

I have similar experience, but by different cause.
My P3 sometimes went almost deaf. When that became frequently, I tried to make troubleshooting.
First, I suspected K3?s IF out buffer amp, but finally I found that the IF interface (between K3 and P3) coaxial cable supplied by Elecraft was the cause.
Either fitting between coaxial cable and BNC connector or BNC connector itself might be wrong. Replacing the cable with my home-made cable have completely solved the problem.

Subject: [Elecraft] K1-2-Band-Module for sale on eBay...
Message-ID: <201801200926.w0K9QIXe020042@mail42c28.carrierzone.com>

Tom,
  Where did you get this idea?  I ship close to two dozen 
international postal packages every year and they are all insurable, 
though the max value does vary by destination country.  For most of 
EU its up to $200 and included in the shipping fee (Not an optional 
charge).  Some countries will give you the option to buy more 
insurance for an extra charge just like its done for shipping within 
the 50 states.  Of course if you are shipping to N. Korea or Iran or 
other such country with little or no trade agreements with the USA, 
then there may not be any insurance available.  You can always make 
that decision on a case-by-case purchase offer.  Carte Blanc refusal 
to sell outside the 48-states (what CONUS usually implies) really 
limits your market.

BTW if you are shipping parcel post instead of priority mail you 
should compare costs.  There is little saving by choosing parcel post.

If you are shipping big expensive items then UPS, etc. may be better.

BTW all my Elecraft purchases were sent via priority mail.  I have to 
go to the PO to get them.  UPS/FedEx just drops the box at my front 
door without alerting me so much higher risk of being stolen.

***I occasionally sell on eBay and I have one simple reason for Conus only.
Packages sent out of the US cannot be insured, at least through USPS, so if
they are lost or damaged you have no recourse.*** Tom, k2bew

I have had excellent luck with the Kent TP-1. It runs a little more than
$125. I think you can pick them up for around $160. It is my main key and I
take it with me everywhere I operate including field day. It has served me
well for many thousands of qso's without the need for re-adjustment or
polishing the contacts.

Larry,

FT-8 is no different than any other data mode, so if other data modes 
work look carefully at the FT-8 computer setup.

One thing I can say is that you must have 4 bars of ALC showing with the 
5th bar flickering.  If you have no indication on the ALC meter, that 
means the K3 is not getting enough audio from your software application, 
and you will have to find out why - perhaps the "power" slider in the 
FT-8 application is set too low.

You might want to take a look at the data mode setup on my website 
www.w3fpr.com.  In the left column scroll down to the last entry and 
click on it to get to the article.

My KX3 cuts off input if the mic gain is set too high. Maybe same issue for your K3?

This says the Line Gain on the K3 is too low.?? Or the PWR slider on the 
WSJT right side is too low.?? Be sure in the F2 menu / Settings, the 
Audio panel has the correct? Audio IN and Audio OUT selected under 
Soundcard.?? Should be USB CODEC.

Don's info is very correct and very complete.?? Don't pay attention to 
what others advise unless they have a K3 or K3S or KX3.? Their advice on 
audio levels will be incorrect as the Elecraft radios handle audio and 
power quite differently the JA radios.

Bob, K4TAX


  When I click the tune button in the FT-8 software, the K3
goes into transmit but there is no RF out.

Ken,

The answer is YES.
See the SUB AF menu on page 60 of the manual.  Basically, if you set SUB 
AF to Balance, you will have the gain of both the main and subRX on the 
AF Gain, and the SubRX gain control becomes a balance knob.

Check audio in level. Too low you will not see RF out.  Too high radio will
go into protect mode with no power out.

Good Evening,

 ??? It has been a very good day to sit by the fire and read.? The best 
time to catch up on my reading is when the power goes out; there is 
nothing else to do :)? A few days reading by kerosene lantern is enough 
to get caught up on month's of books and magazines.? When those are done 
I get out the math books and work on tensors.? Maybe one day they'll 
come naturally.

 ?? The days are a few minutes longer but the sun is no more active.? 
Solar winds have kept the ionosphere from collapsing but only just.? I 
expect my signal will land near the East Coast.? I have been hearing a 
lot of 1 calls very well over the last month. For five to ten minutes 
they have good signals and then the QSB eats them then another signal 
pops out of the mist.

Please join us tomorrow on:

14050 kHz at 2300z Sunday (3 PM PST Sunday)
 ? 7045 kHz at 0100z Monday (5 PM PST Sunday)

Rick,

It is a low profile PC Mount BNC connector.  Elecraft p/n E620075.
See the parts listing in the T1 assembly instructions for a small photo.
It is also used in the KX1.

That cable supplied with the early P3 was a known troublesome cable. Best
replaced.

I have a K3 at a remote site about an hour north of my home so
unfortunately, I cannot quickly investigate an issue that's recently
developed.  After reviewing the K3 schematics, the root cause is likely
isolated to the following parts on the PA board: D36, D37 (BAS70 - Schottky
directional coupler sampling diodes), and/or U16 (LM358 dual op-amp used as
a voltage-follower).  

My question:  are these three parts leaded or SMT/SMD?  Perhaps I'm not
looking hard enough on the Elecraft website but I don't see a detailed
B.O.M. for the K3/K3s.  I want to be ready for replacement without wasting a
two-hour trip to/from the site.  Thanks.

It might mess up the acoustics.

If you have a P3, that would be a good place for a power supply for the 
K3.  Lots of empty space in the cabinet.

Paul,

I have not looked to be certain, but there is a 90% probability that 
they are SMD.

Contact parts at elecraft.com to obtain the part numbers.  Those are not 
normally Field Replacable parts.

Dick & Don,

Thanks for confirming.  Although unlikely to be the source of trouble, It
also appears U6 and U8 are in the VFWD and VREF circuit paths.  I'll order
up everything and have it on hand when I replace this week.  It could also
be a passive problem like a marginally-corroded connector, or failed
resistor.  

By the way, the problem manifests with high SWR and power set readings that
no longer match anything close to  actual output power into known good
loads.  The SWR reading fluctuates excessively with change in the PWR
control and slight changes in the control quickly lead to 120W power spikes
when the K3 display indicates 15-20W.  This tells me the ALC circuit is not
getting a good forward power sample.  So, it appears the SWR bridge or
surrounding circuitry has partially failed.  

Paul

and just tried to run digi.? In audio settings, the audio coded device

shows up on input but does not on output.

Any ideas.

My rig has been to Elecraft twice for other problems that have

Thanks for any ideas.

Paul,

The diodes are the most likely suspect, so replace them first and re-check.

You are correct that the problem is that the wattmeter is not feeding 
the power back to the MCU and the power becomes uncontrolled.

Wattmeter damage is normally a result of static coming in on the antenna 
feedline.  If you do not have an means of disconnecting the antenna when 
not in use, it would be wise to add that - switching the K3 to a dummy 
load would be a good addition too.

that.

The audio CODEC is supported by the native Windows USB Audio Class
driver.  It is independent of the FTDI USB to Serial converter (UART).

If an audio input or output is not visible in the Windows Sound Control
panel, I suggest right clicking on the Recording or Playback window and
checking "Show Disconnected Devices" and "Show Disabled Devices".  Once
you can see the devices, the solution should be obvious.

All,

The Line In level is adjusted with the MIC Gain, and he apparently has 
that working.
Line Out level is a CONFIG menu entry - adjustable from 0 to 30, but 
recommendation is that it not be set higher than 10.

My opinion from the short description is that it is a driver conflict or 
other issue - the output device does not show up in his software.

Hi Don and all,

I really don't understand why static build up on the antenna should be a
problem with the K3. Due to the (good) design of the SWR bridge (a two
transformer design with a voltage transformer right across the output) the
antenna port presents a dead short circuit at DC both in receive and
transmit. I just verified this with an ohm-meter (in receive only - no need
to check in transmit since the SWR bridge is surely present then - don't
want to kill my DMM).

Maybe we are talking semantics here but it appears to me that the cause of
diode damage in the SWR bridge circuit is more likely caused by transients
induced into the antenna system by nearby lightning strikes than static
buildup.

 From experience, I'd say nearby lightning strikes would be the 
culprit.?? I strongly urge everyone to use protection devices on all 
coax and balanced lines at the point where the feed lines and rotor 
lines enter the house.? I prefer Polyphaser devices.?? Don't buy cheap 
or ham fest bargain table crap!? Your radio and your house depends on it.

I don't disconnect antennas nor do I ground antennas.? I protect for 
lightning outside and prefer to choose methods where it will not be 
allowed in the house.??? And I'm on a hill and have two towers? which 
are? 500 ft above average terrain out to some 35 miles.? I understand 
lightning and what it can do.? As to lightning, mitigation is the 
approach, elimination is not physically possible.

I strongly agree with Bob's advice, EXCEPT that I've gotten really tired 
of replacing Polyphasers on my high wire dipoles. I've recently switched 
to the arrestors that Array Solutions sells, both because I like the 
circuit better and because the gas discharge tubes are user replaceable.

The Polyphasers are feed-through types mounted to the entry panel. The 
Array Solutions are mounted in a big Hoffman box, for which W6GJB built 
some custom mounting brackets. It's mounted to the wall next to the 
plate with the Polyphasers, with two 2-in PVC conduit stubs going 
through the wall and holes drilled at the bottom of the enclosure for 
coax entry.

John,

It may be a matter of choice, but I think having a live microphone when 
operating in digital modes is not a good thing.  I would turn MIC+LIN 
off - the MIC SEL to LINE IN for DATA modes.
The only application where I would use MIC+LINE is if I wanted to use a 
software application in voice modes to transmit audio files from the PC 
as well as from the microphone.

In other words, for Soundcard DATA modes, set MIC SEL to LINE.  It is 
mode dependent.  When MIC SEL is set to LINE, the MIC+LIN is turned to 
off automatically.

You *are* running in DATA A mode, are you not?  If not, change to DATA A 
- compression and RX and TX EQ is set flat, that leaves your SSB 
settings "as is" and you do not have to change them when switching 
between voice and data.  All other aspects of DATA A are like SSB.

Don W3FPR

Knut and all,

Yes, BUT...
Lightning is a static charge which *will* produce transients in the 
antenna system.  As will wind static, rain static and snow static. 
Large voltages can build up on the antenna and feedline, and will remain 
until dissipated.  Sort of like a charged capacitor that holds that 
charge until dissipated.  Some of those events can produce very large 
voltages.

So yes, I believe it is a matter of semantics.  Charges of any kind on 
the antenna feedline can cause damage.  The K3 has more protection than 
the K2/KPA100, but that does not make it immune to all events.

Have you ever touched across the terminals of a feedline after a nearby 
lightning event and felt a 'tickle' or even worse?  I have, and it is 
not nice.  A bleeder resistor of 2500 ohms to 50k across the feedline 
will bleed off a static charge in short order.

Even with a lightning suppression device in the feedline, there is still 
a threshold voltage that it responds to.  At voltages less than that 
threshold, the protection device will not be of any assistance in 
bleeding off the charge.

Highly unlikely.  Clear skies for days.  No lightning activity here in a long time here.  Two years ago, I had a similar problem with static-damaged Schottky diodes in an Alpha 9500.  Those diodes are used to sample RF for the amp's EBS circuit.  

>"I strongly urge everyone to use protection devices on all 
coax and balanced lines at the point where the feed lines and rotor 
lines enter the house.  I prefer Polyphaser devices."

Already installed and we never disconnect at the remote site.  The site conforms to Motorola R56.  No lightning-induced damage in almost 3 years of operation in a very lightning-intense location near the Okefenokee Swamp.   High power Alpha-Delta arc-plug devices are located at the master ground bus where all coaxial and control lines enter the station.  Low power (200W) Alpha-Delta devices are installed between the K3 and amplifiers.  The Alpha-Delta devices use field-replaceable arc-plugs.  Like Polyphaser, these devices are intended to mitigate lightning-induced charge, not necessarily antenna static charge.  Still, it's possible that one or more of the Alpha-Delta arc plugs has failed, leaving the K3 vulnerable to static damage. 

In looking at the K3 SWR bridge circuit, both sides of the Schottky diodes have a reasonably low impedance to chassis ground.  One side is slightly less than 22K-ohm.  However, it may not be low enough. To supplement protection, I may add a pi-section 1 mH choke between T3 and the chassis.  It's the same choke used as a static drain in the Alpha 89 and 87A amplifiers to prevent static-induced PIN diode damage, and the type used at the output of many vacuum tube amps to function as a safety device in the event a plate blocking capacitor fails in a shorted condition that would otherwise allow high-voltage on the output network, transmission line, and antenna.

Although fun to discuss and contemplate fixes, it's conjecture until validated and the root-cause may not be related to any of this.

Yes, but...

I believe the original question was about L/R balance while listening to
the main Rx only. This got kicked around on the wish list years ago as
there are many of us with one weak ear. I don't recall hearing that it was
ever done. Don't need a knob for it ... it could go in a menu because I'd
never change it if I could just make my right ear about an S-Unit louder
when using phones.

Some headsets have a balance knob but my favorite ones don't.

Good to see the first reviews!

Can someone comment on the drive requirements?

The FCC document lists a worst case of between 75 and 80W input for 1500W output on some bands. This might be close to the limit of some exciters in RTTY. However, this is still less than the PowerGenius XL which seems to require the full 100W on some bands - again, according to the FCC doc.

There is one eHam review stating that "very little drive power is required".

I bought a couple of these (TT3G50) from DX Engineering.? Unscrewed the gas 
discharge plug, took a look and some photos of the inside construction, and sent 
them back.? Simply awful, (Alpha-Delta, not DX Engineering) ? BTW, the only 
"protection" is a 1000V breakdown gas discharge tube with questionable contact 
to the coax center conductor.

devices use field-replaceable arc-plugs. Like Polyphaser, these devices are 
intended to mitigate lightning-induced charge, not necessarily antenna static 
charge. Still, it's possible that one or more of the Alpha-Delta arc plugs has

Nominal drive power is 50 watts in for 1500 watts out. As with virtually all other amplifiers, drive power requirements can vary from band to band.

Hi Dave,

The synthesizer used in the KX3 doesn?t have means for locking to an external reference. However, if you do the extended VFO temperature compensation, then calibrate the reference to WWV (etc.), you?ll typically be within +/- 1 or 2 Hz of your actual target frequency on all bands, over a wide temperature range.

I cannot find a way to have the K3S remember the power setting per mode.
When switching from Digital modes to CW and having to set the power level
each time is a pain. It would certainly be a welcome feature at this QTH if
the K3S remember the last power setting for each mode as well as each band.

 

Thanks in advance.

Not just mode but mode and each data mode too.

So would somehow automatically adjust the KPA500 base fan setting to be 
mode dependent (mode from K3). The various K3 data modes would most need 
to allow separate values.  I do a lot of mode switching and like to keep 
the KPA500 base fan setting at the lowest value that doesn't result in 
frequent fan speed changes.

Until K9YC's post I was not aware of the Array Solutions lightning
arrestor. They appear be a nice product. How do GDT's fail - open or
closed? If open, how do you know that they need replacement?

The Polyphasers are feed-through types mounted to the entry panel. The
Array Solutions are mounted in a big Hoffman box, for which W6GJB built
some custom mounting brackets. It's mounted to the wall next to the

through the wall and holes drilled at the bottom of the enclosure for

In my experience, they fail shorted, so it's pretty obvious. ? Although 
the app notes for both the ICE and Array Solutions products say that 
they don't always fail shorted.

The design is based on this one, which Array Solutions used to sell, but 
the ICE owner died several years ago. The circuit is shown in the link 
below.? The great thing about this circuit is that the inductor 
continuously discharges static.

This should do it. Actually, once the temp comp procedure has been completed, you?ll have the equivalent of a very expensive TCXO (about +/- 0.2 PPM).

Come on. This is a great little radio. But it?s designed to be s great ?little? portable radio. How many will carry a 10 MHz ref oscillator to a mountain top. 

If you?re looking for a full fledged base station with all the options, get a K3S.

A great little radio it is, agreed. I have two of them that I use as I.F. radios on my 10 & 24GHz portable microwave station setups. They are perfect for that function, using the 2m option as the I.F. especially when mated with a PX3. I drag my microwave gear all over the place, including mountain tops. I phase lock my microwave transverters to a GPS disciplined 10MHz OCXO and would simply like to be able to do the same with the I.F. radio so that I know exactly what frequency I'm on, especially when looking for exceedingly weak transmissions. I know for sure there are many of us microwavers that do the same thing.

FWIW I have a fully loaded K3s in my home station that's also locked to a GPS standard, as is all my RF test equipment.

Message-ID: <014101d3940a$84261b30$8c725190$@gmail.com>

I've been having issues getting my MK2 work with a new-to-me K3 and N1MM+

At the moment, CW works as expected, EXCEPT when I use the footswitch. When use it, the PTT1 light stays lit and the radio goes into transmit and won't get out of it  -- you have to turn off the rig. The PTT! light stays on after the rig's shut off.  You have to turn the MK2 on and off  for the PTT1 LED to turn off. 

When in the phone (SSB) mode, I can key the radio and hear wav files (audio) out of the rig's speaker, but no audio is transmitted.  Likewise, I don't hear anything from the microphone.  The same scenario re-occurs with the footswitch as when in CW. 

 

I originally had an issue of the radio keying and staying keyed when I plugged in the MK2?s PTT cable to the rig. That went away, but I'm not quite sure why or how. 

 

And yes, I have RTFM and N1MM+ setup notes many times. I clearly could have missed something. Just what that may be, I do not know!

 

Thanks & 73,

Message-ID: <201801230836.w0N8aafb018227@mail40c28.carrierzone.com>

Dave,

I bought my KX3 primarily for use as144-MHz mw IF.  I did some 
extensive freq measurements at 6m (before the 2m module was 
available).  I added an aftermarket heat sink and then ran the temp 
comp routine.  I simulated running JT65, which has continuous carrier 
for 50 seconds out of 2 minute sequences and found max drift was 
about 12-Hz.  That existed for the first two sequences and then drift 
dropped down to about 5-Hz (apparently residual heat held the offset 
for a longer time).

Since the 2m module utilizes a 55-MHz IF I would expect about the 
same performance.  Actually depends on power output and 2m max is 3w 
vs the 5w test I ran on 6m.  Seems 12-Hz variation on 10-GHz would 
not be troublesome if the mw LO was phase locked to a reference.  I 
have measured my 10-GHz LO to be about 17-Hz off frequency (no 
discernable drift) mainly due to frequency error in my OCXO on 10-MHz 
(which is multiplied to 10,224.000 MHz from 1,036 MHz).  I drive my 
DEMI 10G transverter at 1w on 144-MHz so drift would even be better.

So freq accuracy is < 17+12 Hz at 10,368 MHz.  Much better than the 
old Xosc system with the FT-817 which could be several KHz off freq.

I use an EIP538 mw freq counter which I check against a Rb source (5x E-11).

Was the MK II previously used with an Icom transceiver?  Is the I
"ICVOX" jumper installed?   See: "Preparing MK II for use" in the

Subject: [Elecraft] Elecraft Power Monitor for P3
Message-ID: <14e2e017-5075-4947-1dc9-6be156b8466b@nk7z.net>

Hello,

I have a new Elecraft P3 transmit power monitor, and it may have a 
problem...

After install I upgraded the firmware on the P3, etc.

When I transmit digital, sometimes it will show full power of 50 watts, 
with a SWR of 1.32:1, which matches my HF-AUTO, and my Ameritron AWM-30 
wattmeter.

The next time I transmit, it may show 20 watts, with a SWR of 1:1, while 
the Ameritron and the HF Auto show all normal at 50 watts, and 1.3ish:1. 
  The next time I transmit, it will show maybe 30 watts, and a 1:1, 
again, the Ameritron, and the HF-AUTO show 50 watts, and 1.3ish:1.

I thought it might just be signal changing due to  being digital, so I 
tried it on CW, same action, the P3 Transmit monitor is all over the 
place, and showing a 1:1 SWR when failed, but 1.34:1 when correct for power.

Next I thought it might be the on and off action from CW showing this... 
  I switched to AM, and with the K3 set at 100 watts, I see 25 watts 
out, and the same action on the P3, all over, while the other two watt 
meters and SWR meters are stable from transmit to transmit...

So thinking it still might be something in my cabling, I replaced all 
cables, and ran the output of the radio to the TX monitor, and the TX 
monitor to a Bird Watt meter, then the Bird to a dummy load...  Same 
thing, the Bird is rock stable, the P3 Transmit monitor seems to be all 
over.  The only thing consistent is that when I get a bad reading on the 
P3 Transmit monitor I am ALWAYS showing a 1:1 on the P3 Transmit monitor.

Just to be sure, I ran the transmit calibration on the K3, and that went 
perfectly well, and succeeded on all bands, at all power levels.  Same 
results with regards to teh P3 Power Level Monitor...

Any ideas?


73s and thanks,
Dave

I missed the original post that began this thread, so the following may or may not be relevant.  I gather the question is about voltage spikes on the antenna or feedline that damaged something nearer the transmitter end.  If that is so, I would ask the original submitter if they are using a remote antenna switch that couples the relay DC through the feedline.  If so, you might examine the switch to see if the proper diode protections are present on the remote relays.  Some time ago I had the PA transistors in a new K2 blown away three times, until Don Wilhelm put me onto an investigation in which I saw on a scope very high voltage short-time-rise spikes on the line when the relay coil fields collapsed, from an MFJ remote switch system that was sold before MFJ changed its design to include those protections.  Just a thought from a bad experience.

     From experience, I'd say nearby lightning strikes would be the 
    culprit.?? I strongly urge everyone to use protection devices on all 
    coax and balanced lines at the point where the feed lines and rotor 
    lines enter the house.? I prefer Polyphaser devices.?? Don't buy cheap 
    or ham fest bargain table crap!? Your radio and your house depends on it.
    
    I don't disconnect antennas nor do I ground antennas.? I protect for 
    lightning outside and prefer to choose methods where it will not be 
    allowed in the house.??? And I'm on a hill and have two towers? which 
    are? 500 ft above average terrain out to some 35 miles.? I understand 
    lightning and what it can do.? As to lightning, mitigation is the 
    approach, elimination is not physically possible.

Was the MK II previously used with an Icom transceiver?  Is the I
"ICVOX" jumper installed?   See: "Preparing MK II for use" in the
MK II Users Manual.

In my experience, they fail shorted, so it's pretty obvious.   Although the app notes for both the ICE and Array Solutions products say that they don't always fail shorted.

The design is based on this one, which Array Solutions used to sell, but the ICE owner died several years ago. The circuit is shown in the link below.  The great thing about this circuit is that the inductor continuously discharges static.

N connectors have better weatherproofing. They handle 1500 V instead of 500 V. But I mostly like them better because they are engineered instead of a historical accident. :-)

While N connectors do have some design and impedance advantages, some of us that have lived in extremely cold climates... have seen the center pins pull out of N connectors due to thermal contraction of the center conductor over distance.  A UHF or DIN connector will usually not do that.

How does that matter for connections inside a weatherproof enclosure 
that mounts the arrestors?? They also have the problem of cable 
migration from the connector.

In 60 years of hamming, I've never seen a quality UHF connector that 
arced. Of course, I've never run more than 1.5kW, and I try to use 
antennas that are close to resonance.? :)

> But I mostly like them better because they are engineered instead of a historical accident.:-)

The technical superiority of N-connectors for use at HF is a wild 
exaggeration, to the extent of being an urban myth. Yes, there is a 
SMALL impedance difference at a junction, but it simply doesn't matter 
at 6M and below, both because the difference in Zo is relatively small, 
because the length is small as a fraction of a wavelength, and because 
as frequency increases, small mismatches are reduced by the loss in the 
feedline (and NOT loss due to mismatch).

There is, of course, a FICTIONAL loss called "mismatch loss," which 
shows up in the lab with test equipment that is carefully engineered to 
have 50 ohm output Z. But the output Z of real world transmitters is 
rarely 50 ohms -- it's usually a lot lower.? Funny -- because it isn't 
real, we didn't learn about it in our transmission lines classes back in 
the '60s.

What matters a lot more is the QUALITY of the connector. Smart hams 
don't use el-cheapo, non-branded connectors. Except for receive 
antennas, I use only soldered Amphenol 83-1SP connectors and mating 
Amphenol jacks and Amphenol adapters.

I?m not trying to convince anyone else to use N-type connectors. I?m just happy they are available.

Yes, there is a SMALL impedance difference at a junction, but it simply doesn't matter at 6M and below, both because the difference in Zo is relatively small, because the length is small as a fraction of a wavelength, and because as frequency increases, small mismatches are reduced by the loss in the feedline (and NOT loss due to mismatch).

Hi Elecraft community,

This is of course OT but relevant information to all K3 owners who are
chasing DX.

They are well underway on their ship closing in on South Georgia Island. You
can trace the ship's course here:

https://share.garmin.com/bouvet

It takes a while to update, but it will. I find it humorous that their
elevation reported appears to change randomly between 100' under water to
more than 100' above. Their main web site is quite impressive but not very
up to date and is not interactive, here:

http://www.bouvetdx.org/

All the action seems to be on Facebook. On their web site there is a link to
their Facebook group in the upper right corner. You can browse all the
content without having a Facebook account. There are a number of nice
videos, mostly from their ship's departure from Punta Arenas. The ship looks
super modern with a ultra modern and high tech bridge.

Again, I apologize to those who are annoyed by OT postings, but this is
after all the DX expedition of this century (likely the most costly in
history) and I have been surprised about how low profile it has had on the
Internet. They are qrv /MM (but their activity seems to mostly CW on 40m. I
have yet to see a spot on the cluster. BTW, Bouvet Island is a Norwegian
possession (undisputed as far as I know) and the crew has two veteran
members, Erling and Just.

I just called Elecraft looking for some parts for my spare K1 and K2 and was told they are out of production.? They are still listed on the order page.
If true, I am very sorry to see them go.? Building my K2 was one of the best experiences of my life.? Thank you, Elecraft.

Pin retraction may depend on your coax. I use a number of N connectors and I
have not seen this occur with Belden 8267 or with the various sizes of
Heliax at my station.

The K1 was discontinued a while ago, I just bought a k2 over the summer
after the K1 was discontinued out of concern the K2 might be next, this is
the first I have heard the k2 was discontinued however.
Hope not,  it?s the only one on the market like it that you can build
yourself, we can only hope that perhaps they will come out with new kit
radio.

N are easier to install than UHF (IMHO), easier to tell that they're installed correctly, and it's difficult to find good quality UHF in larger dia for RG214. UHF for Heliax are very expensive while surplus NOS N-connectors are common. 

That's why I prefer them. I would say UHF offer no advantages over N !

Yup.  Here is a posting I made 25 years ago that has actual data:


From: ... (Alan Bloom)

Date: Fri, 18 Sep 1992 23:03:13 GMT

Subject: The Truth about UHF Connectors

Organization: Hewlett-Packard, Santa Rosa, CA

Newsgroups: rec.radio.amateur.misc



Ya gotta feel sorry for UHF connectors. Recent strings on this notes

group lambasted them as worthless at VHF and above, and barely tolerable

at HF. One poster called them "5 dB attenuators", and many agreed that

there must be some sort of conspiracy among ham equipment manufacturers

to inflict such garbage connectors on the amateur community.



Today I finally remembered to bring some UHF adapters from home so I

could do some relative measurements of UHF versus type-N.  As expected,

the type-N showed lower insertion loss at high frequencies, but the UHF

connectors were hardly "5 dB attenuators."



For the test I connected an HP8753 RF network analyzer through two short

BNC cables into the following arrangement:

    _______    ____________    ___________    ____________    _______

   |       |  | BNC female |  | N female- |  | N male to  |  |       |

__| 10 dB |__| to N male  |__| N female  |__| BNC female |__| 10 dB |__

   | Atten.|  | adapter    |  | adapter   |  | adapter    |  | Atten.|

   |_______|  |____________|  |___________|  |____________|  |_______|



Then I repeated the measurement with the N adapters replaced with UHF.

I normalized the measurements by replacing the 3 adapters with a BNC

double-female. (That is, this was assumed to have 0 dB loss.)



Since two N or UHF adapters were used, I assume the loss per connector

is half the total. The vertical scale was .1 dB/division, so I estimated

the insertion loss to the nearest .01 dB or so:



             --------- Type N --------   ---------- UHF ----------

FREQ (MHz)  TOTAL  LOSS PER CONNECTOR   TOTAL  LOSS PER CONNECTOR

1.8         0 dB   0 dB                 0 dB   0 dB

30          0      0                    0      0

100         0      0                    0      0

150         0      0                    0.02   0.01

200         0      0                    0.03   0.015

450         0      0                    0.18   0.09

600         0      0                    0.26   0.13

900         0      0                    0.66   0.33

1000        0.05   0.025                0.8    0.4

1300        0.1    0.05                 0.86   0.43

1600        0.05   0.025                0.5    0.25

2000        0.05   0.025                0.02   0.01



Insertion loss increases until about 1300 MHz, and then starts to

decrease until it is almost zero for the UHF connector at 2 GHz!  At

that frequency, the connectors are about 1/4 wave long (1 inch,

assuming .66 velocity factor), so I assume that the two adapters are

providing a conjugate match to each other. This confirms my assumption

that the insertion loss is due to reflections (impedance mismatch), not

absorption (true power loss).



Bottom line: UHF connectors work fine through the VHF range, and are not

too bad even on the 420 MHz band if you can stand about .1 dB mismatch

loss per connector.



By the way, I did not do the full 2-port calibration on the HP8753, so

there was a couple hundredth's dB ripple in the plots. I averaged this

out by eye to come up with the numbers in the above chart.

Eric,

The K2 is still current production, but the K1 is no longer available, 
as is the KX1.

Parts should still be available, although part number substitutes may 
have to be used in some cases - in the case of the K2, all parts are 
still available except for those that have been superceded by the 
current parts.  I order parts regularly.

If you send me a list of what you need, perhaps I can help.

I is not always thermal related.  Center pin retraction can also be 
caused by stress on the coax.  I have seen many N male connectors where 
the shield has slipped in the clamp due to tension on the coax (from the 
weight of hanging or perhaps other causes).  I routinely do 2 things - 
1) put a bead of silicone seal around the coax to top of the N connector 
junction, and 2) support the coax in some manner about 12 inches from 
the connector.

If the shield slips in the connector body, the most obvious result is 
center pin retraction, but it may also be that the shield has broken (or 
hanging on by a thread) allowing the coax to come partially out of the 
connector.

The same problem can be found in BNC connectors.

In other words, do not let the connector take the stress of the hanging 
coax weight.

Well soldered UHF connectors do not have that problem.

It's important to remember that when the "UHF" (239 series) connectors were
developed, UHF meant 28 MHz! Almost no work was being done at over 100 MHz
and the FCC did not even care what one did over 300 MHz: My 1941 ARRL
handbook shows that Hams could do whatever they wanted at such absurdly high
frequencies, nor does the handbook show how to produce RF above the 112 MHz
band (112 became 144 MHz when the FCC reorganized the early TV channel
allocations.)  

That changed very quickly during WWII. Wars do have a habit of spurring
technological development. But the name "UHF" stuck with the SO and PL 239
connectors. As Alan points out, they are quite useful up into what we call
VHF and possibly low UHF today.

Yup.  Here is a posting I made 25 years ago that has actual data:


From: ... (Alan Bloom)

Date: Fri, 18 Sep 1992 23:03:13 GMT

Subject: The Truth about UHF Connectors

Organization: Hewlett-Packard, Santa Rosa, CA

Newsgroups: rec.radio.amateur.misc



Ya gotta feel sorry for UHF connectors. Recent strings on this notes

group lambasted them as worthless at VHF and above, and barely tolerable

at HF. One poster called them "5 dB attenuators", and many agreed that

there must be some sort of conspiracy among ham equipment manufacturers

to inflict such garbage connectors on the amateur community.



Today I finally remembered to bring some UHF adapters from home so I

could do some relative measurements of UHF versus type-N.  As expected,

the type-N showed lower insertion loss at high frequencies, but the UHF

connectors were hardly "5 dB attenuators."



For the test I connected an HP8753 RF network analyzer through two short

BNC cables into the following arrangement:

    _______    ____________    ___________    ____________    _______

   |       |  | BNC female |  | N female- |  | N male to  |  |       |

__| 10 dB |__| to N male  |__| N female  |__| BNC female |__| 10 dB |__

   | Atten.|  | adapter    |  | adapter   |  | adapter    |  | Atten.|

   |_______|  |____________|  |___________|  |____________|  |_______|



Then I repeated the measurement with the N adapters replaced with UHF.

I normalized the measurements by replacing the 3 adapters with a BNC

double-female. (That is, this was assumed to have 0 dB loss.)



Since two N or UHF adapters were used, I assume the loss per connector

is half the total. The vertical scale was .1 dB/division, so I estimated

the insertion loss to the nearest .01 dB or so:



             --------- Type N --------   ---------- UHF ----------

FREQ (MHz)  TOTAL  LOSS PER CONNECTOR   TOTAL  LOSS PER CONNECTOR

1.8         0 dB   0 dB                 0 dB   0 dB

30          0      0                    0      0

100         0      0                    0      0

150         0      0                    0.02   0.01

200         0      0                    0.03   0.015

450         0      0                    0.18   0.09

600         0      0                    0.26   0.13

900         0      0                    0.66   0.33

1000        0.05   0.025                0.8    0.4

1300        0.1    0.05                 0.86   0.43

1600        0.05   0.025                0.5    0.25

2000        0.05   0.025                0.02   0.01



Insertion loss increases until about 1300 MHz, and then starts to

decrease until it is almost zero for the UHF connector at 2 GHz!  At

that frequency, the connectors are about 1/4 wave long (1 inch,

assuming .66 velocity factor), so I assume that the two adapters are

providing a conjugate match to each other. This confirms my assumption

that the insertion loss is due to reflections (impedance mismatch), not

absorption (true power loss).



Bottom line: UHF connectors work fine through the VHF range, and are not

too bad even on the 420 MHz band if you can stand about .1 dB mismatch

loss per connector.



By the way, I did not do the full 2-port calibration on the HP8753, so

there was a couple hundredth's dB ripple in the plots. I averaged this

out by eye to come up with the numbers in the above chart.

Paul:
I had a problem with my K2 with the same identical symptoms you are
describing.

The fault was diagnosed to an intermittent ground/shield connection in the
RF output

Cable going to my amplifier.  It was an old cable that was out in the
weather and when 

I took it apart you could see the corrosion in the PL259 inside the holes
for grounding.

This cable worked for me for several years but recently failed.  

Bring some extra jumper coax with you.

Hi Elecraft community,

This is of course OT but relevant information to all K3 owners who are
chasing DX.

They are well underway on their ship closing in on South Georgia Island. You
can trace the ship's course here:

https://share.garmin.com/bouvet

It takes a while to update, but it will. I find it humorous that their
elevation reported appears to change randomly between 100' under water to
more than 100' above. Their main web site is quite impressive but not very
up to date and is not interactive, here:

http://www.bouvetdx.org/

All the action seems to be on Facebook. On their web site there is a link to
their Facebook group in the upper right corner. You can browse all the
content without having a Facebook account. There are a number of nice
videos, mostly from their ship's departure from Punta Arenas. The ship looks
super modern with a ultra modern and high tech bridge.

Again, I apologize to those who are annoyed by OT postings, but this is
after all the DX expedition of this century (likely the most costly in
history) and I have been surprised about how low profile it has had on the
Internet. They are qrv /MM (but their activity seems to mostly CW on 40m. I
have yet to see a spot on the cluster. BTW, Bouvet Island is a Norwegian
possession (undisputed as far as I know) and the crew has two veteran
members, Erling and Just.

Correct installation is usually the key.? The line must be supported no 
more than 12" from the connector and NEVER at any time by the connector, 
even during installation.?? Also, line supports along all vertical and 
horizontal runs is a must.

Hi

Must be having a senior moment  - but while I have VFO  A and B linked
nicely on 80 - can't do it on 40..
instructions say
"Holding SUB  links the VFOs (whether the sub
receiver is on or off). The kHz decimal point of
VFO B flashes as a reminder. "

But the instant you press 'SUB' - it turns on without linking; and then any
further 'hold' turns on diversity.

What am I doing wrong?

John,

You apparently missed the Firmware Release notes.
VFO Linking has been moved from the SUB button into a menu item.

There was a timing relationship on the SUB button - a long hold used to 
turn on Linking, but it was confusing to a number of operators so it was 
changed.

directly into diversity receive, without first having to go through 
"LINK". This should benefit most users of the KRX3 sub receiver, since 
few use the VFO linking function. Those who do use VFO linking can still 
turn it on by setting CONFIG:VFO LNK to ON. This menu entry can be 
assigned to a programmable function switch for easy selection if 
desired, eliminating the need to bring up the menu.

Hi

Must be having a senior moment  - but while I have VFO  A and B linked
nicely on 80 - can't do it on 40..
instructions say
"Holding SUB  links the VFOs (whether the sub
receiver is on or off). The kHz decimal point of
VFO B flashes as a reminder. "

But the instant you press 'SUB' - it turns on without linking; and then 
any
further 'hold' turns on diversity.

What am I doing wrong?

Thanks  John VE3NFK

The elevation discrepancies are normal - I see the same effect whendriving around down here in South Florida, randomly dropping to 10-20feet below sea level. The civilian GPS systems are not configured forextreme elevation accuracy, particularly when close to sea level.

The main web site's?position reporting may be outdated because, I think,that they're relaying their position via satellite (Iridium, perhaps?) whichcan get pretty expensive. Given the length of the journey, it's probablynot worthwhile providing hour-by-hour position updates. They'll get therewhen they get there, and they'll get on the air after they get things set up.

Karin,

Many thanks.  I have several extra RG-400 jumpers that can be used as well
as confirming if the issue appears on ANT-2.  Schottky diodes arrive
tomorrow, so I'll be ready later this week.  I'll report back on the final
fix.

The elevation changes seen with civilian GPS are the result of two 
fairly fundamental issues:

1.? A GPS receiver doesn't really "know" where actual sea level is, it 
uses a mathematical model.? Since the earth is ellipsoidal-ish rather 
than spherical on a large scale, and since there are smaller local 
variations, the model is a trade-off between accuracy and complexity.? 
On State Route 37 just north of San Francisco, you are immediately 
adjacent to San Pablo Bay and can see that you're about 10 ft above it.? 
My Garmin GPS pegs my elevation at 61 ft.

2.? The second is "dilution of precision," or DOP.? The relative 
positions of the satellites in the sky change constantly, and finding 
your coordinates is a process of finding the intersection point of lines 
of position [LOP] from multiple satellites.? When the satellites are 
scattered all over the sky, many of the LOP's intersect at large angles 
[90 deg is ideal] and the intersection is well defined.? If the 
satellites are more or less lined up in one area of the sky, the LOP's 
tend to intersect at smaller angles and the exact intersection point is 
less well defined.? This is Horizontal DOP or HDOP.

Unfortunately, when it comes to elevation [VDOP], roughly half the 
satellites are below the horizon at any given time, there are thus fewer 
LOP's to work with, and the probability of finding large-angle LOP's is 
inherently lower.? Hence, VDOP is usually [almost always] greater than HDOP.

Thus endeth GPS 101.

I also think they are communicating using some service on the Iridium 
constellation which is probably expensive, and the ship is only making 
around 10 kts or so, so more frequent updates wouldn't indicate much.? 
Given the overall expense of this expedition however, communications 
costs are probably below the round-off. [:-)

Yep.? The "civilian channel" on GPS was a gift to everyone from the US 
Department of Defense, I suppose they could turn it off if they so wish, 
but it is so ingrained in today's culture that they won't.? Years ago, 
the channel was purposely perturbed to limit the horizontal accuracy to 
something between +/-100 to 200 meters.? It was called "Selective 
Availability."

The US Coast Guard [another branch of the US military] promptly 
installed GPS receivers in very carefully surveyed key locations, and 
published the error between the known position and the GPS reported

you can receive if your K3 has the new synthesizer [and you have the

At the risk of taking us further off topic?..

SA was turned off in May of 2000 by executive order.
https://www.gps.gov/systems/gps/modernization/sa/ <https://www.gps.gov/systems/gps/modernization/sa/>

The position quality transition brought on by the shutdown of SA was a milestone event for the marine research community (among many others.) This event was captured at the time by many and is characterized by the amazing graph on the page above - fond memories.  Some (many of our tiny community) stayed up and watched the data show the transition in real-time - after stumbling around the world?s oceans for a decade it was AWESOME. 

I?ve been working with GPS/GNSS receivers (mostly on research ships at sea, but some geodesy) since the early 1980s when our ?portable? (two full height relay racks) Y-set had two HP 2100s and a 9-track tape drive see: https://www.ion.org/museum/item_view.cfm?cid=7&scid=9&iid=43 <https://www.ion.org/museum/item_view.cfm?cid=7&scid=9&iid=43> (the picture only has the receiver hardware, it took serious comping in that era to derive real-time solutions and log the data. Now our cellphones and watches do it.)   Moving that system from ship to ship set the bar for my Compaq ?luggable? later on ;-)

A substantial part of the early orbit-correction data collection and analysis that led to differential GPS was led by the civilian surveying and geodesy community trying to figure out how to get high accuracy post-processed solutions during SA.  (Not unlike the amateur radio digital experiments that led to packet radio?

I still do no not take GPS (and GNSS) for granted.

Hi again,

Well, the recent posts have indeed taken us farther OT. While the original
GPS 101 posting was excellent  information, we are now well past the
overload on GPS details (and politics). The ship is now well past South
Georgia Island. They acknowledge that their ship borne antennas leave them
with weak signals (both ways of course). Hopefully that will change once
they get their beams up on the island. Can we please drop the GPS subject?

Message-ID: <201801251154.w0PBsmnm031667@mail101c40.carrierzone.com>


I was running some stations on 160-meters this morning, and noted that the power output had dropped from the amp.

Further investigation found that the maximum power out from the K3/100 was reduced from ~100W to about 54W, with no error messages displayed on the K3. Advancing the 'PWR' control beyond 54 W made no difference. I stopped operating, and found that the power slowly restored, first to a maximum of 84W, and then back to the normal 100W maximum.

I assume that this is an issue with temperature? The ambient temperature was cool (A/C running in shack). I have not noted this problem before.

The fan was set to 'Config > KPA3 > PA nor'.  recommended setting for hard contest use?

K1 & K2 owners, I have for sale excess to my needs now:


(1)  for the K1/K2 transceivers:


the K6XX CW Indicator with False Blink kit, LED Button Option & header connect/disconnect option.  These work well on the K1 and fairly well on the K2.  NOTE:  the kit requires soldering of SMD components prior to installation of the header.  Don Wilhelm installed mine and did a great job.


$39.95 plus $4.5 USPS.


(2)  for the K2, the Rework Eliminator kit to ease the task of changing microphone types.  Same price.


I also have a spare color decal showing the mic positions for the Rework Eliminator.  If you have the old black & white or your's is peeling, these are great.  $1 plus a USPS first class mail stamp.


For the K3 and K3s I still have:

two 2.7 kHZ 5-Pole filters        (make an offer)

Either one or both filters are $9.95 shipping which comes with tracking & insurance, 2-3 Day USPS Priority Mail.

Cheers,

Doug W5JV

Subject: [Elecraft] KPA1500 ATU - ability to handle more than two antennas
Message-ID: <1516909730590-0.post@n2.nabble.com>

While I'm awaiting the delivery of my KPA1500 I'm wondering if/how the amp's
ATU can accommodate more than two antennas.  For example, if I have an
antenna switch connected to one of the amp's antenna jacks is there a
facility on the amp that would allow me to choose one of two /logical/
antennas beyond the ANT1 / ANT2 physical selection?  Having two sets of
memories per band per physical port would accommodate 4 antennas.  

Does the KPA1500 support this or something similar to allow for more than
two antennas?  If not,  this seems pretty simple to implement as a firmware
change - assuming there's enough memory available.  If memory is a
constraint I suppose you could provide the option to halve the number of
tuning solutions stored per segment to keep the memory footprint the same.

Thanks,

Dan

You may want to give a more specific description.  Remote control f/w is usually not  specific to a brand of radio. Its just amp specific.

Dan,

The KPA1500?s firmware is written to accommodate many more antennas. It would be a fairly simple matter to externalize a number of them in the form of a remote-controlled antenna switch. 

This is a good example of how the amp can be tailored to user needs. The firmware could be updated to support an external switch, patch it into the normal antenna selection process (i.e. ATU retuning, ANT switch control), display its number or noun name on the LCD, etc. We even have two user-programmable switches (PF1 and PF2) that could be used as hot-keys to select specific antennas, rigs, or other configurations.

As unique station needs arise, we?ll try to address them in a timely fashion. To that end, feel free to recommend specific third-party antenna switches that we could test. We?ll work with the manufacturers to ensure smooth operation.

73,
Wayne

You may want to give a more specific description.? Remote control f/w is usually not? specific to a brand of radio. Its just amp specific.

While I'm awaiting the delivery of my KPA1500 I'm wondering if/how the amp's
ATU can accommodate more than two antennas.  For example, if I have an
antenna switch connected to one of the amp's antenna jacks is there a
facility on the amp that would allow me to choose one of two /logical/
antennas beyond the ANT1 / ANT2 physical selection?  Having two sets of
memories per band per physical port would accommodate 4 antennas.  

Does the KPA1500 support this or something similar to allow for more than
two antennas?  If not,  this seems pretty simple to implement as a firmware
change - assuming there's enough memory available.  If memory is a
constraint I suppose you could provide the option to halve the number of
tuning solutions stored per segment to keep the memory footprint the same.

Thanks,

Message-ID: <1917A1F1-C862-41E0-ACFF-C7CCBFC088D1@mac.com>

I just built my KPA500 today and on the air reports were good. 20watts Drive seemed right for about 500 watt peaks. After running it for about an hour I shut down to clean up the kit building mess and when I returned later I was hearing a loud 60 cycle mechanical buzz from the left side of the cabinet when in operation. The buzz would vary from very light when keyed with no drive to quite loud when putting out 500 watts CW. I had not noticed any noise earlier but I was wearing Bose noise cancelling headphones as I normally do.

The voltage looks normal under load and the output power is 500 watts with a little over 20 watts drive.  

I removed the top cover, loosened the transformer mounting bolt a bit, turned it up on its left side to make sure the transformer was resting against the two bumpers and retightened the mounting screw per the instructions.  This did not result in any change in the mechanical vibration. 

Any suggestions?

Multiple (4 to 6) antenna connectors is a nice feature of Expert amps. Once
you have antenna matched, QSY to up to 2-3 antennas per band is automatic.
The psychological effect is astounding, as trying to get SWR as close to 1:1
is becoming a waste of time. In my Expert 2k-fa I have 5 antennas connected. 

Having two antenna connectors is probably enough for heavy duty contesters
where sophisticated antenna selection together with SO2R  is done
externally.

However, Elecraft can provide several logical antennas software selected,
with each one matched separately. They can also come with an external
switch.  

Only 2 connectors is a reason why I am not placing the order for KPA1500. 

Ignacy, NO9E

My KPA500 (that I built about a year ago) buzzes in the same way as
Michael's.
My transformer is hard against the rubber buffers, the double-rubber pads
are properly in place, and the bolt is nicely torqued down. I'd be
interested in hearing any ideas to mitigate this issue also.

I'm concerned about the same issue:? Multiple antennas on one band. I 
have an automated antenna selection system.? In addition to following 
the band data from the transceiver, there are switches to select 
antennas.? I frequently have to very quickly switch antennas, so it must 
involve only a single switch.? Using a mouse with the computer is 
nowhere near fast enough and I really don't want to make it dependent on 
the computer, anyhway.? However, my antennas have different impedances, 
so require different ATU settings.? So, how can I tie the KPA1500 ATU 
into my antenna control switch so it automatically switches settings?? 
All the antenna switching is external to the amp, so only a single amp 
output is used.? The ideal would be a control line to the amp, 
controlled by the same switch that selects antennas, which would select 
ATU settings.? I really don't want to make it dependent on the 
computer.? I expect others have the same issue.? Can the KPA1500 be made 
to do something like this?

Message-ID: <CAOmNKGJA4RjHySnv7KvXjKxQjzRDAe6_q7LQDEHx0dMfBZEtsg@mail.gmail.com>

To review, the Y-BOX provides a reliable and convenient way to connect the
K3 ACC port to multiple devices, including the KAT500, KPA500, KPA1500,
band decoders, DigiKeyers, RemoteRig boxes, etc.  The Y-BOX replaces any
15-pin Y-Cables you may already be using.

While supplies last (I only have a few left), the original "Version 1.3"
Y-BOX will be sold for only $129 ea. (originally $139).  Order this version
if you don't have a SteppIR controller, or don't have a requirement to
power a KPA500 or KPA1500 on or off remotely.  Version 1.3 requires an
Elecraft KPAK3AUX cable (not supplied) for connecting the Y-BOX to an
Elecraft amplifier or tuner.

For the eham.net reviews, please see
https://www.eham.net/reviews/detail/13296

The new "Version 2.1" Y-BOX dedicates one connector for a KAT500, KPA500,
or KPA1500, with no KPAK3AUX cable required.  Simply connect an economical
15-pin M/F cable (but not a VGA cable) between the Y-BOX v2.1 "AMP AUX"
port and your Elecraft device.  The Y-BOX will connect only the required
lines, emulating the wiring of the KPAK3AUX cable.

Version 2.1 also adds two new internal headers. The first is optionally
used to open the keying line to the amplifier, providing convenient RCA
connectors for SteppIR owners with a SteppIR Tuning Relay (a device which
opens the keying line whenever the antenna is tuning).

The second header optionally connects the DIGOUT1 line of the K3 to the
Elecraft amplifier's PWR ON pin, so you can remotely power the amp. ON or
OFF with a simple K3 macro, or your K3 logging software.  This technique is
documented in the K3 Remote Owner's Manual
<http://www.elecraft.com/manual/K3%20Remote%20Owner's%20Manual%20%20Rev%20D.pdf>,
on page 21.  With the Y-BOX version 2.1 and a 15-pin M/F DE-15 cable, no K3
to KPA500 cable modification is required; the required connection is made
inside the Y-BOX.

Version 2.1 is now available to order, priced at $139 ea.  Here's a direct
link to the order form:

https://goo.gl/forms/Guu6OC6NinTlasY93

For more details and photos, please see https://bit.ly/Y-BOX (freshly
updated to show what's new in version 2.1).

Thanks again for all your support and encouragement.

If you have the ATU, it can be fooled into thinking you have a 
bad match by AM broadcast stations nearby. If you have a nearby 
broadcast transmitter, a band reject filter is one solution.

Message-ID: <c073fcc0-06a6-988d-da5d-e2feeb8ceb1b@ca.rr.com>

 From the KAT-500 owners manual the power ratings are as follows:

3?30 MHz 600W into 5 ? to 500 ? (10:1 SWR).
 ??? ???? 1000W into 16 ? to 150 ? (3:1 SWR).

1.8-2.0 MHz 600 W into 10 ? to 500 ? (5:1 Low Impedance, 10:1 High 
Impedance SWR).

Does anyone know what the power rating is for 160 meters when the tuner 
is in bypass mode?

I would like to put my Alpha 87A in front of the KAT-500 and run the 
KAT-500 in bypass mode on 160 meters at 1500 watts, and then at reduced 
power on the other bands where I am actually using the tuner to match 
the antenna. This is for a remote setup, so it is not convenient to 
physically take the tuner out of amplifier's output path on 160 meters.

Thanks,

Hi Mike,

I have a pair of KAT500's in my SO2R station. They're currently fed by a 
pair of 87As, and before that, a pair of TenTec Titans. Both are legal 
limit amps using the same tubes. My antennas are all close enough to 
resonance that I can use the tuners in bypass mode and use the 
amplifier's output network to keep the tubes happy.? I have an LP100A 
inline with both amps, and, for legal limit contests, I keep the power 
right there. The KAT500s are happy with that arrangement. They were NOT 
happy in Man mode above about 1 kW, and the level at which they got 
unhappy was reduced increased mismatch.

Hi Stephen,

I have used Eyoyo brand similar to this one as a computer monitor

It is fine for the purpose.

Mine is about 2 months old and has buzzed during key-down since I first
powered it up.  Just figured it was that giant toroidal transforming doing
its thing.

Message-ID: <ffacf5bf5acdd4e05b71a602bfe9f576.squirrel@www11.qth.com>

I have original versions of the Y-Box. Although it worked, I never liked
using multiple Y's on the ACC jack and this box eliminated the clutter.
Both of mine work perfectly. Also Bob is very responsive and a great guy
do business with.

I assume that the amplifier port has certain terminals not connected, the
Elecraft cable is missing these pins. Are there devices that need these
pins?  Is it possible that someone would need four unmodified ACC jacks?

To review, the Y-BOX provides a reliable and convenient way to connect the
K3 ACC port to multiple devices, including the KAT500, KPA500, KPA1500,
band decoders, DigiKeyers, RemoteRig boxes, etc.  The Y-BOX replaces any
15-pin Y-Cables you may already be using.

While supplies last (I only have a few left), the original "Version 1.3"
Y-BOX will be sold for only $129 ea. (originally $139).  Order this version
if you don't have a SteppIR controller, or don't have a requirement to
power a KPA500 or KPA1500 on or off remotely.  Version 1.3 requires an
Elecraft KPAK3AUX cable (not supplied) for connecting the Y-BOX to an
Elecraft amplifier or tuner.

For the eham.net reviews, please see
https://www.eham.net/reviews/detail/13296

The new "Version 2.1" Y-BOX dedicates one connector for a KAT500, KPA500,
or KPA1500, with no KPAK3AUX cable required.  Simply connect an economical
15-pin M/F cable (but not a VGA cable) between the Y-BOX v2.1 "AMP AUX"
port and your Elecraft device.  The Y-BOX will connect only the required
lines, emulating the wiring of the KPAK3AUX cable.

Version 2.1 also adds two new internal headers. The first is optionally
used to open the keying line to the amplifier, providing convenient RCA
connectors for SteppIR owners with a SteppIR Tuning Relay (a device which
opens the keying line whenever the antenna is tuning).

The second header optionally connects the DIGOUT1 line of the K3 to the
Elecraft amplifier's PWR ON pin, so you can remotely power the amp. ON or
OFF with a simple K3 macro, or your K3 logging software.  This technique is
documented in the K3 Remote Owner's Manual
<http://www.elecraft.com/manual/K3%20Remote%20Owner's%20Manual%20%20Rev%20D.pdf>,
on page 21.  With the Y-BOX version 2.1 and a 15-pin M/F DE-15 cable, no K3
to KPA500 cable modification is required; the required connection is made
inside the Y-BOX.

Version 2.1 is now available to order, priced at $139 ea.  Here's a direct
link to the order form:

https://goo.gl/forms/Guu6OC6NinTlasY93

For more details and photos, please see https://bit.ly/Y-BOX (freshly
updated to show what's new in version 2.1).

Thanks again for all your support and encouragement.

The amplifier port on the Y-BOX v.2.1 (labeled "To AMP AUX") normally has
no connection on pins 1, 4, 6, 7, and 8.  The AUX port on the Amplifier
uses these pins for special purposes not related to the K3, as documented
in amplifier manuals.  For example, pin 1 and pin 6 on the amp. are used
with Icom radios to get Band Data.  Pin 7 can be connected to an audio
alarm (drives low for fault).

Using a standalone Y-BOX connected to the amplifier AUX with a 15-pin M/F
cable, you can "break out" these special pins to any of the four RCA ports,
making it easier to connect non-Elecraft devices to an Elecraft amp.

The four "unmodified" jacks on the Y-BOX v1.3 could be used with:

   1. KPAK3AUX cable (to an amp)
   2. Remote Rig cable
   3. microHAM MK2R+ SO2R box
   4. Top Ten Band Decoder / Antenna switch

(Since none of these cables wire all 15 pins; connecting them all in
parallel works fine).

uses FSK and PTT connections via the AUX jack.

If there are only two antennas per band, perhaps this is doable with
dual-input antenna switch (like DXE-RR2X8B) and Microham StationMaster. For
each band, MH SM selects one antenna for A and another one for B. To change
an antenna within a band,  select A  or B in the amp or via CAT.

Hi Guys,


I'm wondering if anyone is using your K3S to send RTTY via AFSK and you remember which Configuration settings are required to get the K3S to send AFSK with N1MM Logger+? ? My K3S got knocked around by UPS in shipment and I had to download the latest K3S firmware to resolve some other issues. ?Now the K3S will only transmit RTTY in DATA A mode and not AFSK A mode so I'm thinking perhaps a Config setting is wrong. ?
?
Thanks,

This is definitely doable from the amp. All it takes is an external antenna switch with a control port compatible with RS232, Ethernet, USB, or one of the amp?s multi-purpose digital output lines. (These have other uses, too, such as SWR alarm output.)

To select among antennas from the amp, you could do any of the following:

- tap the ANT switch to go between two or more antennas in rotation

- tap ANT then use the UP/DN switches

- assign two frequently-used antennas to the front-panel PF1 and PF2 switches

In all cases, the LCD would show your selection from among N external antenna jacks.

We can adapt the firmware to handle any such scenario.

In addition to following the band data from the transceiver, there are switches to select antennas.  I frequently have to very quickly switch antennas, so it must involve only a single switch.  Using a mouse with the computer is nowhere near fast enough and I really don't want to make it dependent on the computer, anyhway.  However, my antennas have different impedances, so require different ATU settings.  So, how can I tie the KPA1500 ATU into my antenna control switch so it automatically switches settings?  All the antenna switching is external to the amp, so only a single amp output is used.  The ideal would be a control line to the amp, controlled by the same switch that selects antennas, which would select ATU settings.  I really don't want to make it dependent on the computer.  I expect others have the same issue.  Can the KPA1500 be made to do something like this?

Even if you?re not considering purchasing a KPA1500, you might want to read the reviews recreationally. They?re all very well-written, in stark contrast to some of what passes for informed opinion on the web these days. Who knew our early amp buyers would all be English majors? :)

How about using an external switch to select which ATU settings the amp 
uses?? Perhaps with a digital INPUT line?

Greetings KX2 users. I have developed an app for iPhones and iPads that is a comprehensive guide to using the KX2. This app was developed in response to requests from many KX2 users for an app like the ones I?ve created for the KX3 and other Elecraft products. 

It is available in the Apple App Store for a small fee. Search for ?KX2 Micro Manual? or ?Mike Downs, ks7d? to see a list of all my apps for Elecraft products. 

Those of you that use Android phones, please let me know, off list, if an Android version would be desirable.

Not to belittle your effort; what I've done is download the .PDF manuals 
into my (free) Dropbox account, so that no matter where I am or what 
device I am using (presuming it's mine), I have access to those files.? 
There is a flavor of Dropbox for almost any current device.

I do the same with my .ADIF file (log backup); other manuals and documents.

The only thing you must do is make sure it's downloaded into the device 
before you're out of Internet coverage (and expect you might need it).

Good luck in your project, it's nice to have many ways to get the needed 
tasks done.

I had a similar problem with one of my K3's (#4576) starting last November.
Seemingly at random, output power dropped to around 35 watts.  At low
power settings (less than 12 watts) power was limited to 3.5 watts.  Sometimes
normal power output would be restored in a couple of hours,  other times I had
to turn the radio off for a day or two.  In December I sent it back 
to Elecraft to
find and fix the problem.  It is still there so I don't know what the 
problem was.

Mike,
I'm very happy with your KX3 Micro Manual; FB.   I'd buy the KX2 manual in
a New York minute, but I don't own the rig.  LOL

Rick,
I do the same thing with the Elecraft downloads and store them in
Evernote.  I have all my KX3 resources available at my fingertips and with
an integrated PDF search function.   The advantage of Mike's manual is that
it's optimized for the iPhone platform, has an integrated search function,
and has a relatively small footprint.

As with Fred's Cady's KX-line manual, the Micro Manual bears looking at.
 Where the Elecraft PDF is the Encyclopedia Brittanica, I see Mike's Micro
Manual as Cliffs' Notes on steroids for the KX line.

Disclaimer; No financial interest in the Mike's work, just a satisfied user
with a KX3.

I think this is a very important aspect of station design and a big
consideration for any future amp purchase I make.

I'd like to respectfully suggest that Elecraft consider designing a
bulletproof 16x2 antenna switch rated for 5KW and 10:1 SWR (and lots of
isolation between ports) that integrates seamlessly with the amp and
tuner.

There is typically a need to switch both antennas and high power bandpass
filters, or at least the high cost of high power bandpass filters makes
using only one for each band (via switching) very useful.

So when the amp QSYs to 40m the ideal scenario allows the switching in of a
40m bandpass filter after the amp, and then whichever antennas are usable
on 40m, with the tuner knowing which antenna was chosen so that it can
switch to the previously known settings for instant TX.

Matt NQ6N

I just upgraded to the KXV3B with internal preamp, so have for sale from my
K3 (SN 431):

One-owner PR-6, 6 meter-only preamp, at 0.5 dB, actually lower NF than my
new one <g>. This comes with original docs, both interface cables (one to
+12 V, one to AUX) with connectors, both double-male BNC connectors to
support and provide RF interface to K3. It can work fine with other
receivers, just promise you won't transmit through it. Looks and works like
new. Current price $160, my price $100 + $10 for regular shipping to CONUS
only. This is not needed if you have a K3S.

One-owner KXV3A Transverter interface for K3. This is needed for the PR-6
(or PR6-10) preamps, and not only for external transverters, but also for
the internal 2-meter transverter. It also provides an IF output for use with
a P3 panadapter or other SDR. It was working fine when I removed it
yesterday, and includes original documentation and all needed hardware and
cable.
The K3S comes with the KXV3B, so does not need this.

I will sell this for $100, half the cost of the new KXV3B, plus $10 shipping
to CONUS only.

If you want both, I will pay shipping. I don't do paypal, so either postal
money order or personal check drawn on US bank -- shipping upon clearance.
Or better yet, bring cash to my house, by arrangement!

Subject: [Elecraft] Fldigi issue
Message-ID: <00de01d396f9$c5c80700$51581500$@comcast.net>

Hello All,

 

I had Fldigi setup fine on my desktop computer before I had to pack it away
8 months ago for a move.  I am predominantly a CW ops and have just used my
Begali HST III to key my KX3.  I am currently enrolled in the CWOps Academy
level 2 class. Which I am enjoying very much.  I am currently sending and
receiving at about 25 wpm and my instructor mentioned that we could look at
Fldigi to see how we are sending.

 

I have a SignaLink USB interface that I have, I think, correctly connected
to my laptop.  My KX3 is connected to my KXPA100 and the usb interface from
the KXPA100 to my laptop.  The cord coming out of the "Radio" connection at
the rear of the SignaLink is attached to the Mic input on the KX3, and the
"Spkr" connection to my phones connection on the KX3.

 

I have Fldigi RigCat interface and correct config file working between
Fldigi and my rig.  As I turn the VFO, the display in Fldigi moves
accordingly.

 

I receive signals in CW fine and Fldigi decodes them fine in the upper
window.  When I click in the lower window, I can type text with my keyboard
for transmission, then transmit them through my rig.  

 

All those features work fine.  The problem is, when I key the keyer which is
plugged into my Key input on the KX3, nothing shows up in Fldigi.  My keyer
transmits code as normal, but nothing shows up on either Fldigi screen.

 

Perhaps that is the way it should work; with only keyboard, but I am stumped
as to how to set things up so I can see my keying in Fldigi as my instructor
suggests.

 

Thanks for any input you can give me.

 

Very 73's,

 

Terry de N7TB

Who would spend 30 hours+ building an Elecraft K2? Well, me, for one.
I built the very first K2, not long after Eric and I sketched out the design on napkins right in the middle of Field Day at Henry Coe state park. (Some claim this is mythology, but I was there :)  That first unit wasn?t even painted, and we had yet to design the option modules. 

Since then, nearly another 8,000 times someone else has asked that same question, concluding that the answer was ?yes." It?s worth asking why.

Features? 

The K2 is very light in weight for an all-HF-band/multi-mode desktop-style rig (3 lbs). The transmitter puts out 15 watts (100 W with the bolt-on KPA100 top cover), and the receiver has been proven crunch-proof over many subsequent Field Days. 

Is that why this little radio--our first product--just refuses to become obsolete?

Maybe it's the crisp sound of the 100% analog superhet RX strip. Or the continuously tunable, variable-passband 4.9 MHz crystal filter. Or the blazingly fast break-in CW.

Could it be ease of operation? The K2 has only the most essential controls--excellent for first-time users--and an embarrassingly small number of menu entries compared to most modern rigs. 

But when I think back on it, now, I believe the real reason for the K2?s popularity must be that it?s fun to build. Not just fun, but rewarding: transforming several bags of carefully labeled bagged components and hardware into a complete ham transceiver, then putting it on the air. (Somewhere I have a logbook page that says ?First QSO on prototype K2!? that I should frame. It was a unique experience.)

Speaking of parts, 100% of those used in the K2 have leads. There?s nothing wrong with surface mount construction, but leaded parts are easier to handle, harder to lose, and more clearly labeled. This makes for a reassuring, enjoyable assembly process, even if you?ve had just a little prior experience building.

What got me started on this email was a quick browse through some of the over 300 reviews of the K2 posted on eHam.net:

   http://www.eham.net/reviews/detail/117

The enjoyment and pride of building really shines through. This is why Eric and I started the company in 1998, and it?s why we still offer the K2 only as a full kit. (Yes, you?ll need a good soldering iron. Our tech support team will be happy to recommend one if you?re shopping around.) 

Many customers have teamed up with their kids or grandkids on the build. In my book, this beats letting them binge-watch Netflix all weekend. Even if your co-builders aren?t hams (yet), they?ll have great fun helping you identify and install parts.

That, in fact, is pretty easy. One of the best things about the K2 is the assembly manual:

   http://www.elecraft.com/manual/E740001_K2%20Owner%27s%20Manual%20Rev%20I.pdf

The manual is written in tutorial style, including finer points like the resistor color code, photos of all parts and modules, and detailed signal tracing/troubleshooting instructions. The manual has been refined to the point that it?s virtually foolproof. Of course if you have any difficulties, you can always ask a question on the Elecraft reflector, day or night, or check in with customer support.

For those of you who are just now thinking about tackling the K2, we?ve decided to sweeten the deal a little. Consider it an early Valentine?s gift. You can find our K2 specials near the top of this page:
   
   http://www.elecraft.com/elecraft_prod_list.htm

I?ll leave you with this photo of two early production K2s. It was taken in 1999 from inside a VW van I used to own (the radio is reliable, the van wasn?t). S/N 00002, in the foreground, was being operated by Eric, WA6HHQ, except that he?s also the photographer. In the background is yours truly, complete with a Field-Day?s worth of facial hair and tie-dyed T-shirt, operating S/N 00001.

*I built mine in 1999 and still love it. Your right about the great

My first rig was a K2 borrowed from my dad K6PJV. Had to give it back 
when I bought my K3 but I missed it so much I bought a used one in need 
of repair. Added the K6XX CW tuning indicator and a fixed audio output, 
got WAS on JT-65 with it using less than 8 watts. I won't give it up.

I have always thought that real hams build their own equipment 
and uber hams design and build their own equipment. I guess that 
makes Wayne a uber ham.

While the Owners Manual is indeed super, the single largest aid for me 
was having all the resistors taped in the order of insertion.? I'm 
colorblind, I checked each with the ohmmeter as I was about to select it 
[normal procedure for me], but that one thoughtful feature removed a 
huge number of possibly screw-ups for me while building it, had I been 
required to sort them all out in advance.? Mine worked perfectly when I 
first went through the test procedures.

Nice work guys!

It has been more than 4 decades since I built a Heathkit radio with my father. Having had the pleasure of buying and using a second-hand K2/10, I didn't need much convincing that I wanted to build a K2/100, and so I did just that over the Christmas/New Year's holidays. 

Now my K2/100 is setup in my DxVacation QTH in Vietnam and my very first QSO was with VU2USA in India using a  Buddipole antenna. 

The K2 was not overly complex, and I didn't even mind winding the toroids. I suspect building the kit in 30 hours is achievable...but take your time and enjoy the process and take pride in a radio that is pretty darn amazing.

Who would spend 30 hours+ building an Elecraft K2? Well, me, for one.
I built the very first K2, not long after Eric and I sketched out the design on napkins right in the middle of Field Day at Henry Coe state park. (Some claim this is mythology, but I was there :)  That first unit wasn?t even painted, and we had yet to design the option modules. 

Since then, nearly another 8,000 times someone else has asked that same question, concluding that the answer was ?yes." It?s worth asking why.

Features? 

The K2 is very light in weight for an all-HF-band/multi-mode desktop-style rig (3 lbs). The transmitter puts out 15 watts (100 W with the bolt-on KPA100 top cover), and the receiver has been proven crunch-proof over many subsequent Field Days. 

Is that why this little radio--our first product--just refuses to become obsolete?

Maybe it's the crisp sound of the 100% analog superhet RX strip. Or the continuously tunable, variable-passband 4.9 MHz crystal filter. Or the blazingly fast break-in CW.

Could it be ease of operation? The K2 has only the most essential controls--excellent for first-time users--and an embarrassingly small number of menu entries compared to most modern rigs. 

But when I think back on it, now, I believe the real reason for the K2?s popularity must be that it?s fun to build. Not just fun, but rewarding: transforming several bags of carefully labeled bagged components and hardware into a complete ham transceiver, then putting it on the air. (Somewhere I have a logbook page that says ?First QSO on prototype K2!? that I should frame. It was a unique experience.)

Speaking of parts, 100% of those used in the K2 have leads. There?s nothing wrong with surface mount construction, but leaded parts are easier to handle, harder to lose, and more clearly labeled. This makes for a reassuring, enjoyable assembly process, even if you?ve had just a little prior experience building.

What got me started on this email was a quick browse through some of the over 300 reviews of the K2 posted on eHam.net:

   http://www.eham.net/reviews/detail/117

The enjoyment and pride of building really shines through. This is why Eric and I started the company in 1998, and it?s why we still offer the K2 only as a full kit. (Yes, you?ll need a good soldering iron. Our tech support team will be happy to recommend one if you?re shopping around.) 

Many customers have teamed up with their kids or grandkids on the build. In my book, this beats letting them binge-watch Netflix all weekend. Even if your co-builders aren?t hams (yet), they?ll have great fun helping you identify and install parts.

That, in fact, is pretty easy. One of the best things about the K2 is the assembly manual:

   http://www.elecraft.com/manual/E740001_K2%20Owner%27s%20Manual%20Rev%20I.pdf

The manual is written in tutorial style, including finer points like the resistor color code, photos of all parts and modules, and detailed signal tracing/troubleshooting instructions. The manual has been refined to the point that it?s virtually foolproof. Of course if you have any difficulties, you can always ask a question on the Elecraft reflector, day or night, or check in with customer support.

I've always liked the term "FunkMeister" which is German for senior or master radio operator.

I am but a mere "funker."

So... if Wayne is pushing a design
concept, would that make him a Uber

Thanks for taking the time to post that, Wayne! I was a little worried we
were about to hear of the K2 going EOL.

Almost exactly a year ago I bought a K2 and have since built every option
available, and it has been a joyous experience. I just love every aspect of
the K2. It is my favorite (non-Heath) radio, and among my most prized
possessions. I would also like to mention Don Wilhelm being one of the
contributing factors toward making the K2 building and ownership experience
so great. Anyway...thanks to you and Eric for the K2 - I am "Elecraft for
life".

I have built three, two with the 100 watt amp, two with the SSB option, all with tuners either inside or out, and all with every other accessory I can get into them.  I don't know why I haven't bought a fourth, yet.  Maybe the special will move me to it.  The build, which for me is multiples of 30+ hours, is half the fun.   The other half is using one on the air.  When I operate in contests I always begin with the K3 - KPA500 - KAT500 and then, at night, I use a K2. I don't know why it's more relaxing, but it is.  Nostalgia?  Maybe.

    Who would spend 30 hours+ building an Elecraft K2? Well, me, for one.
    I built the very first K2, not long after Eric and I sketched out the design on napkins right in the middle of Field Day at Henry Coe state park. (Some claim this is mythology, but I was there :)  That first unit wasn?t even painted, and we had yet to design the option modules. 
    
    Since then, nearly another 8,000 times someone else has asked that same question, concluding that the answer was ?yes." It?s worth asking why.
    
    Features? 
    
    The K2 is very light in weight for an all-HF-band/multi-mode desktop-style rig (3 lbs). The transmitter puts out 15 watts (100 W with the bolt-on KPA100 top cover), and the receiver has been proven crunch-proof over many subsequent Field Days. 
    
    Is that why this little radio--our first product--just refuses to become obsolete?
    
    Maybe it's the crisp sound of the 100% analog superhet RX strip. Or the continuously tunable, variable-passband 4.9 MHz crystal filter. Or the blazingly fast break-in CW.
    
    Could it be ease of operation? The K2 has only the most essential controls--excellent for first-time users--and an embarrassingly small number of menu entries compared to most modern rigs. 
    
    But when I think back on it, now, I believe the real reason for the K2?s popularity must be that it?s fun to build. Not just fun, but rewarding: transforming several bags of carefully labeled bagged components and hardware into a complete ham transceiver, then putting it on the air. (Somewhere I have a logbook page that says ?First QSO on prototype K2!? that I should frame. It was a unique experience.)
    
    Speaking of parts, 100% of those used in the K2 have leads. There?s nothing wrong with surface mount construction, but leaded parts are easier to handle, harder to lose, and more clearly labeled. This makes for a reassuring, enjoyable assembly process, even if you?ve had just a little prior experience building.
    
    What got me started on this email was a quick browse through some of the over 300 reviews of the K2 posted on eHam.net:
    
       http://www.eham.net/reviews/detail/117
    
    The enjoyment and pride of building really shines through. This is why Eric and I started the company in 1998, and it?s why we still offer the K2 only as a full kit. (Yes, you?ll need a good soldering iron. Our tech support team will be happy to recommend one if you?re shopping around.) 
    
    Many customers have teamed up with their kids or grandkids on the build. In my book, this beats letting them binge-watch Netflix all weekend. Even if your co-builders aren?t hams (yet), they?ll have great fun helping you identify and install parts.
    
    That, in fact, is pretty easy. One of the best things about the K2 is the assembly manual:
    
       http://www.elecraft.com/manual/E740001_K2%20Owner%27s%20Manual%20Rev%20I.pdf
    
    The manual is written in tutorial style, including finer points like the resistor color code, photos of all parts and modules, and detailed signal tracing/troubleshooting instructions. The manual has been refined to the point that it?s virtually foolproof. Of course if you have any difficulties, you can always ask a question on the Elecraft reflector, day or night, or check in with customer support.
    
    For those of you who are just now thinking about tackling the K2, we?ve decided to sweeten the deal a little. Consider it an early Valentine?s gift. You can find our K2 specials near the top of this page:
       
       http://www.elecraft.com/elecraft_prod_list.htm
    
    I?ll leave you with this photo of two early production K2s. It was taken in 1999 from inside a VW van I used to own (the radio is reliable, the van wasn?t). S/N 00002, in the foreground, was being operated by Eric, WA6HHQ, except that he?s also the photographer. In the background is yours truly, complete with a Field-Day?s worth of facial hair and tie-dyed T-shirt, operating S/N 00001.

I must be the only K2 owner who found the construction (40+ hrs) just... tedious.  But it was worth it. Bought it July 1999 and still using it, still qrp and still occasionally busting pileups. Everyone's different.


I'll probably get a K3 one day (kind of expensive), but the K2 us doing fine in the mean time.

Howdy,

Thanks Wayne for the look back. Great stuff! 

Like others, my K2 is not for sale. No matter what other rigs may grace my shack, the K2 stays. Nope, I didn't build it (I'm all thumbs), but, besides being a super performer and just tons of fun, being a gift from my first guide dog upon his retirement (with help, naturally, from other humans), it has huge sentimental value. Thanks Karl. 

Come to think of it, I think Elecraft has been something of a tradition for important milestones. The KX1, I got when I went to Ukraine to adopt our daughter in 2004. It's now living with a longtime friend and partner in mischief. The KX3 I got myself as a 25th hamiversary gift. What's next? 

Vy 73,

You may actually find the answer you're looking for in the N1MM Logger+
documentaation. It has a section on configuring for the K3/K3S.

Hi Guys,


I'm wondering if anyone is using your K3S to send RTTY via AFSK and you
remember which Configuration settings are required to get the K3S to send
AFSK with N1MM Logger+?   My K3S got knocked around by UPS in shipment and
I had to download the latest K3S firmware to resolve some other issues.
Now the K3S will only transmit RTTY in DATA A mode and not AFSK A mode so
I'm thinking perhaps a Config setting is wrong.

Thanks,

Lenny,

You might want to consider doing all the A to B upgrades to that K2, and 
that includes changing the IF crystals on both the K2 RF Board as well 
as the KSB2 filter bandwidth to the current 2.4kHz.  If you have the 
KPA100, it can likely benefit from the KPA100UPKT and the new shield.
A fully upgraded K2 will perform like a new K2.

Don W3FPR

My first receiver was a low-price National - just barely usable - along
with a HeathKit DX-20. My first really good receiver was in K2 #5957
with amp/ssb/dsp/NL. Since then I've gathered together the K-line
station units, and I am completely satisfied with them. That said, the 
K2 is the radio for Field Days. Others in the club bring their whole 
home station.I bring the K2 (and a few support items in a small basket), 
operate 40m CW, and am fortunate to be able to make a contribution to 
our club score. If I had to make a forced choice between the two radios, 
I'd pick the K2. The K3 is much the better radio, yet the K2 has deeper 
roots in my heart. It's one of my dearest treasures.

Thanks, Wayne and Eric, and all those working and helping at Elecraft!

First licensed in 1952, I've never felt as good operating any rig as one I
built myself, either from scratch like my first Novice rig or at the very
least from a kit. 

I still remember running net control during a Civil Defense exercise from
W6CV in Southern CA, a station owned by a good friend with a beautiful
collection of National and E.F. Johnson equipment and, after the exercise
was over as I drove home in my '47 Studebaker eagerly looking forward to
putting my homebrew 6L6 oscillator on the air in the 80 meter novice band.
Doing that was more exciting because I had worked out the circuit from an
old handbook and built it on an salvaged chassis, complete with a tank coil
made out of (door) bell wire wound on a circle of nails. 

My station was completed with a homebrew superhet - several of them over
time. 

Because of that background my K2, built in 1999, is still my favorite rig in
spite of the K3S it shares my shack with. I was an eager participant in many
of the upgrades it got in the first few years, happy to modify the circuits
and do the required testing.  

For SOME of us, the "magic" of cobbling together the parts, working out the
circuit, building and putting a rig on the air is more important than our
contest scores or DXCC standing.

Howdy,

Thanks Wayne for the look back. Great stuff! 

Like others, my K2 is not for sale. No matter what other rigs may grace my
shack, the K2 stays. Nope, I didn't build it (I'm all thumbs), but, besides
being a super performer and just tons of fun, being a gift from my first
guide dog upon his retirement (with help, naturally, from other humans), it
has huge sentimental value. Thanks Karl. 

Come to think of it, I think Elecraft has been something of a tradition for
important milestones. The KX1, I got when I went to Ukraine to adopt our
daughter in 2004. It's now living with a longtime friend and partner in
mischief. The KX3 I got myself as a 25th hamiversary gift. What's next?

I don't think it's desirable to have the amplifier controls external 
antenna relays.? One might sometimes want to operate barefoot.? Besides, 
there are external antenna relay boxes available, as well as 
programmable controllers.? (And a few of us dinosaurs are using homebrew 
antenna controllers.)? In any case, an external controller can easily be 
made to switch antenna relays, bandpass filters, etc. Another advantage 
of doing all the antenna switching external to the amplifier is it 
allows using a single coax, which can easily be disconnected when 
there's lightning about.

If one already has the antenna switching and control set up, the ONLY 
new thing the amplifier has to do is to be able to switch the ATU among 
2 or more sets of parameters for each band, and have some way the 
external control system can tell the amplifier which set to use.? My 
preference would be some logic inputs to the amplifier, say 3 bits, 
which would allow 8 sets of parameters for each band.? (That might be 
excessive, but maybe not for some of the big muli-multi stations.? I'd 
settle for 2 bits, or even 1.) Using a serial port forces the user to 
use either a computer or a controller with a serial port, not compatible 
with simple homebrew systems.

My system, for example, has a toggle switch to select one of my two 
tribanders.? I can switch back and forth several times in a second when 
trying to determine which direction the signal is coming from.? I can't 
possibly manipulate more than one switch that fast, nor to I want to 
have to reach over to wherever the amplifier happens to be, and I 
certainly don't want to be messing around with a mouse.? (While all this 
antenna switching is going on, the other hand is running the radio.)

Hi all,

Look at this video from their ship:

They have slowed down to 2 knots (from 10-11). This storm might delay their
ETA by several days.

My first transceiver was an IC-7000. Suborned by the pretty display.
Elecraft was too plain looking. Then I put together a KX1, and realized
there was something to Elecraft. I didn't want to drop the bucks on a full
K2 kit, so to Ebay I went, where I got a late model K2 with a couple of
problems left by the original builder. After finding and fixing those, and
adding the K6XX and MAB mods, this K2 has become my primary shack
transceiver. Nothing else has lured me away - except for the KX3 and KX2
that are now my portable and travel rigs. Strangely, in the shack, I
actually enjoy using the K2 more than the KX radios.

Still in the back of my mind, I keep thinking I will at some point buy a K2
kit to build myself. Hopefully I won't wait too long.

Subject: [Elecraft] Wrong PIM nuts in KPA500 kit
Message-ID: <0P3800B5W1YTQ410@ms11p00im-qufv17100601.me.com>

I am waiting on a response from Elecraft TS on this one but I thought I would ask if anyone else has encountered this problem on the KPA500 kit.

On the bottom edge of both the right and left side panels there are places for three 6-32 flat head screws.  The countersunk holes are obviously larger than those for the other 4-40 flat head screws.

In my kit one of the three PIM nuts, for each side, was the correct 6-32 thread PIM nut and the remaining two had 4-40 PIM nuts installed in the bottom cover.  When I had temporarily installed the left hand side panel in the middle of construction I failed to notice this and just installed screws that fit (one 6-32 and two 4-40) but during final assembly it became obvious that the 6-32 screws would not fit in 4 of the 6 positions.

Thinking that they just had paint in them I tried tp run a 6-32 tap through one and it naturally seized up and twisted the PIM nut out.  Not being the brightest bulb in the shop I tried that a second time and twisted out the second PIM nut.

Fortunately these were both on the right hand side where there was room to slip two 6-32 hex nuts in place and I just used two 4-40 flat head screws on the left side.

Hopefully Elecraft will be able to send me the correct PIM nuts to replace the four incorrect ones.  That was my request in the email to Doug at tech support.

I certainly would not want to replace the bottom coverl as that would require a complete disassembly of the amplifier.

Has anyone else encountered this?

My switch uses an Arduino to read the band lines from the K3 and 
select the last antenna(s) used on that band. It the code could 
easily be modified to tell an antenna tuner -- in the K3, an 
amp, or separate -- which antenna system is in use. Manual 
switching is with a button for each antenna.

I designed my station controller over 20 years ago.? Since I'm a 
hardware designer, it's all hardware. I suppose, however, something like 
your Arduino could be programmed to read the antenna switch and send a 
serial command to the amplifier, though that seems a lot of trouble.

This posting from Wayne, N6KR, pretty much explains why I've been an 
Elecraft guy since August 2011 when I signed up for a factory built 100W 
K3 with a few options.... and haven't regretted it a day since.

A first rate product, first rate support and first rate company.

I pasted a teaser for those who may have not waded through all the

Microham Station Master listens to K3 traffic, decodes frequency and sets
switches as programmed. This is regardless whether the amp or computer are
on. Also very reliable unit. Can also be used for as rotator controller. I
cannot praise it enough. 

I have Expert 2k-fa and it is  a love-hate relationships. On one hand, 2
input and 6 outputs with a reasonable antenna tuner. I switch bands and
antennas, and no extra work. On the other hand, it failed 4 times, the PS
supply creates RFI (fixed partially by a large toroid), and it is pretty
loud., requiring headsets all the time. Also, ability to control antennas
outside of front panel (or an unreliable app) is variable under Flex only
(DDUTIL). 

Expert 1.3k-fa has RFI quiet PS and is very light. Its back fans are quiet
but the one insides is annoyingly loud - apparently fixed in newer models.
Also only 4 antenna outputs. But it was brilliant working with KX3 as
CE0Y/NO9E. 

So I am looking for an Expert replacement -quiet both acoustically and RFI,
as automatic and with good CAT. Perhaps KPA1500-2 will be it.

Break out the Dramamine.

Some years ago a very seasoned commercial sailor told me; "there's not a 
man alive that under certain sea conditions, won't toss his cookies".??? 
After a few trips, I too learned that to be true.? I later inquired 
about what to eat for breakfast??? He said, "bananas,? namely because 
they taste the same coming up as going down."

I was first licensed in 1952 and spent my senior year in HS using the
modified ARC-5 transmitter and Hallicrafters S-40 receiver in the HS
radio club room - W2CLE, allegedly the oldest HS radio club in the US
(1912).

My next excursion into HF was the pair of Hallicrafters SX-101A and
HT-32B that I used from 1965 through mid-1967 when I was 4X4UQ in
Israel.  55 countries (the easy ones, of course) over 28 months Nice to
be DX for a change.

Returning to the 'States in 1967, went back on 40 meters for about 3
years, then sold those rigs because my main activity was VHF/UHF and
didn't get back on HF until I got the K2 in 2006.  Because of my
degraded close-up eyesight (monocular), I couldn't build it myself, but
a local ham friend did it for me.  Fully loaded K2 of course for working
HF 'phone and digital modes.  If I had known and waited another year or
so I could have had a K3 but that's another story.

I couldn't put up any decent HF antenna after moving to this
ground-floor apartment 5 years ago, so the K2 sits "ready to go"
connected to a short end-fed wire antenna - not a very effective
radiator.  Except for contests, I don't hear anything.  But I can hope.

I enjoy reading all the K2 love stories. Thanks for sharing them.  I 
returned to building gear after a thirty-plus year absence and got my 
amateur license as an excuse to buy a soldering station. I build small 
stuff now and doing a little homebrewing. There is nothing like using a

four kits and a year's worth of squirreling away cash from building a K2

I've built two K2s. The second one was serial number 1250, which at the
time was my street address. Nice catch. ;)

When it came time to prepare to evacuate from the Butte Fire a couple years
ago, after the usual essentials were packed, the K2s went in the car next.

Wayne, when we gonna get another K2-level kit? :) 73 jeff wk6i

Ignacy,

How is he trying to load the memories.  He must use paddles connected to 
the K2 directly and not from an external keyer or a straight key.

Is he pushing the buttons correctly?  Does he know the difference 
between a button tap and a hold?

I considered buying the Expert 2K, but decided against it because there 
was no apparent way to tie the ATU into my antenna switch.? I'm not sure 
there is? or will be with the KPA1500, either, but it is much more 
attractive based on Elecraft's reputation.? Besides, I've since built an 
external tuner, which IS tied into my antenna switch, which matches both 
tribanders almost perfectly, so it won't even be necessary to use the 
ATU.? That was, however, a lot of work.

 (plus: special pricing)
Message-ID: <201801272212.w0RMCFYP022886@mail40c28.carrierzone.com>

This almost has me ordering one.

My first kit was in summer of 1958 (I was 14).  $19.95 bought me a 
3-tube regen receiver - Knight kit Ocean Hopper (with all band 
coils).  I didn't even have a soldering iron which my Dad bought me 
for $5.95 for my birthday.  I had several Heathkits and Hammarlund 
and Clegg and a EF Johnson which were all off-shelf.  Later some 
Kenwoods, Yaesu's, and Icom's, even two Tentec.

Since then, I have built many surface-mount kits from DEMI and W6PQL, 
etc.  I'm near the end on SM and retired my kit making business last 
spring.  This fall I learned I will no longer be climbing towers.

If I did not already own a K3, KX3 (w/2m module), and KXPA100,  I 
might be interested in the QRP version of the K2 to use as IF for 
mw.  Guess I got enough on my plate to get finished.  But an 
intriguing thought.

Message-ID: <DAEF37A9CA284169BB8C8AAD6C54E278@DESKTOPAV61F2H>

HI,
Ok a strange thing happened today.  I was moving my K3 from one rack to another and once everything was connected up I turned it on. Now I use an external speaker and the volume was so loud that it blew.  I immediately turned down the volume and went to the speaker in the K3.  Barely touching the volume control resulted in such a high volume level that I was afraid the speaker would blow there too!.
I checked the menu setting for the AF Gain and it was set to high which I have always used since I found the audio out of the K3 was too low for me.
Now, I?ve had to put it at low and it seems that it is now back to the way it was.
So is it really that loud on High and why would I have not seen this before?
Thanks, Tom

Break out the Dramamine.

Some years ago a very seasoned commercial sailor told me; "there's not a man alive that under certain sea conditions, won't toss his cookies". After a few trips, I too learned that to be true.  I later inquired about what to eat for breakfast?   He said, "bananas,  namely because they taste the same coming up as going down."

The dynamic range of the K3 is so great that this is possible, at least 
for an external powered speaker.

There is a setting in the menu for limiting the audio output.  While it 
makes the audio horrid, it does limit the levels, thus saving your 
speaker...

My guess is you have your AGC off...  I leave mine turned on, but have 
adjusted it to be as ineffective as possible, and only kick in on really 
strong signals.

73s and thanks,
Dave

This posting from Wayne, N6KR, pretty much explains why I've been an
Elecraft guy since August 2011 when I signed up for a factory built 100W
K3 with a few options.... and haven't regretted it a day since.

A first rate product, first rate support and first rate company.

I pasted a teaser for those who may have not waded through all the

All this talk about K-2?s makes me homesick for the one I built shortly before my retirement (Serial #5529). I spent an entire summer carefully following the instructions and created an astonishing radio. Sometime after that, the lure of the K-3 took over and I sold my K2 to finance the purchase of the K-3. I now regret that decision.

If anyone out there knows who has my old K-2 please contact me off-list. I?d like to discuss reacquiring the radio. If you tell me you have the radio but it?s not for sale, just tell me how it?s doing.

Tom, I had the same issue a week ago, but only with one mode (data A). It was
far louder than any other mode and I had to change the line out setting from
10 to 1 in order to use data modes like FT8.
I tried EE INIT but no change. I went back to an earlier config file and it
became normal. I even went through the exercise of printing out the entire
Menu and Config settings, then loading each into the rig and writing down
the settings while scrolling through the radio. I couldn't find any
differences. Regardless if I loaded the latest config file it didn't work
and if I went back to an older one it corrected the problem. Possibly trying
an older config file will fix your problem too?

As they say, YMMV, good luck.

Hi,
No the AGC is On.  It's still overall several times higher than I have ever 
heard when in High.
That's very strange since I always had it at high and when I first checked 
it was at High.
So now if I put it to low is is as it has always been. Putting it at high 
with AGC off, I will now blow any speaker attached!

Message-ID: <e3e2da69-0508-0976-9f59-2c68efa5f464@coho.net>

Good Evening,

 ??? The rainy season coincides with the logging season. Since it is so 
wet fire danger is near zero. Skidding logs during the dry season can 
start fires just from the friction between logs. During the wet there is 
little need for the fire watch crew to stand guard for a week after a 
clearcut has been graded and transported to the mill. Normally the 
loggers cut stands in full sections so the Coast Range is a checkerboard 
on a mile square grid. On my way to town this week I passed through four 
active sites before I got to my mailbox in Buxton.

 ?? When you meet a logger in town they are easy to recognize. The 
thousand yard stare is a tipoff, they are dead tired from on the job 
since 4 AM. Their attire is obvious too: suspenders, no belts - ever; 
they?re wearing slippers; and the cuffs of their jeans have been ripped 
off with both seams cut upward an inch or two. The slippers are because 
they normally wear corks which would shred any flooring or the cab of 
their truck. Suspenders and ripped seams are due to the nature of their 
work. Most non-fatal injuries are from being crushed by logs so the 
ripped seams and suspenders allow rapid access to their limbs.

 ?? Mostly they make great neighbors except for being awakened by large 
timber hitting the earth or when they drop stumps into very large steel 
containers. Luckily the sound only carries about five miles or so and 
you get used to the whumping sounds over the years. Each time they open 
a new block the view of the terrain opens up too. I can now see the top 
of my mountain from a number of angles.

Please join us tomorrow on:

14050 kHz at 2300z Sunday (3 PM PST Sunday)
 ? 7045 kHz at 0100z Monday (5 PM PST Sunday)

73,
Kevin. KD5ONS

I did in 2007. K2/100 #4684.
An hour or so after work each night...maybe not if I had a bad day. Weekends were filled with everything K2/100 and add-ons. Mine is fully "stuffed".

Sad part is I couldn't do it again. Since then I have lost about half of my eyesight. A couple of badly detached retina's from a fall and six surgeries for two eyes.

I will never sell that rig.

Subject: [Elecraft] Who would spend 30 hours+ building an Elecraft K2? (plus: special pricing)

Who would spend 30 hours+ building an Elecraft K2? Well, me, for one.
I built the very first K2, not long after Eric and I sketched out the design on napkins right in the middle of Field Day at Henry Coe state park. (Some claim this is mythology, but I was there :)  That first unit wasn?t even painted, and we had yet to design the option modules. 

Since then, nearly another 8,000 times someone else has asked that same question, concluding that the answer was ?yes." It?s worth asking why.

Features? 

The K2 is very light in weight for an all-HF-band/multi-mode desktop-style rig (3 lbs). The transmitter puts out 15 watts (100 W with the bolt-on KPA100 top cover), and the receiver has been proven crunch-proof over many subsequent Field Days. 

Is that why this little radio--our first product--just refuses to become obsolete?

Maybe it's the crisp sound of the 100% analog superhet RX strip. Or the continuously tunable, variable-passband 4.9 MHz crystal filter. Or the blazingly fast break-in CW.

Could it be ease of operation? The K2 has only the most essential controls--excellent for first-time users--and an embarrassingly small number of menu entries compared to most modern rigs. 

But when I think back on it, now, I believe the real reason for the K2?s popularity must be that it?s fun to build. Not just fun, but rewarding: transforming several bags of carefully labeled bagged components and hardware into a complete ham transceiver, then putting it on the air. (Somewhere I have a logbook page that says ?First QSO on prototype K2!? that I should frame. It was a unique experience.)

Speaking of parts, 100% of those used in the K2 have leads. There?s nothing wrong with surface mount construction, but leaded parts are easier to handle, harder to lose, and more clearly labeled. This makes for a reassuring, enjoyable assembly process, even if you?ve had just a little prior experience building.

What got me started on this email was a quick browse through some of the over 300 reviews of the K2 posted on eHam.net:

   http://www.eham.net/reviews/detail/117

The enjoyment and pride of building really shines through. This is why Eric and I started the company in 1998, and it?s why we still offer the K2 only as a full kit. (Yes, you?ll need a good soldering iron. Our tech support team will be happy to recommend one if you?re shopping around.) 

Many customers have teamed up with their kids or grandkids on the build. In my book, this beats letting them binge-watch Netflix all weekend. Even if your co-builders aren?t hams (yet), they?ll have great fun helping you identify and install parts.

That, in fact, is pretty easy. One of the best things about the K2 is the assembly manual:

   http://www.elecraft.com/manual/E740001_K2%20Owner%27s%20Manual%20Rev%20I.pdf

The manual is written in tutorial style, including finer points like the resistor color code, photos of all parts and modules, and detailed signal tracing/troubleshooting instructions. The manual has been refined to the point that it?s virtually foolproof. Of course if you have any difficulties, you can always ask a question on the Elecraft reflector, day or night, or check in with customer support.

For those of you who are just now thinking about tackling the K2, we?ve decided to sweeten the deal a little. Consider it an early Valentine?s gift. You can find our K2 specials near the top of this page:
   
   http://www.elecraft.com/elecraft_prod_list.htm

I?ll leave you with this photo of two early production K2s. It was taken in 1999 from inside a VW van I used to own (the radio is reliable, the van wasn?t). S/N 00002, in the foreground, was being operated by Eric, WA6HHQ, except that he?s also the photographer. In the background is yours truly, complete with a Field-Day?s worth of facial hair and tie-dyed T-shirt, operating S/N 00001.

Tom,
     Something comes to mind. Go into the setup menu and check the AGC 
threshold. As you move it up in number, the audio output goes up, and it 
takes a greater signal amplitude before it "kicks" in. I usually use 
this when using data A to prevent AGC capture, or at least as much, by 
other signals in the passband, for instance FT8 with a received 
bandwidth of 2.5KHz. Normally, the K3 AGC is excellent and should have 
prevented what you describe unless the the AGC threshold is too high.

73,
Barry

HiYes but it's weird that never arose in the past.?The one thing that IS different this time is that the radio had a full power down. Not just the front panel....?73 Tom?

2 knots?
That would usually be too slow to pass enough water by the rudder to
maintain steering control.

Wayne,

I've been trying to convince SWMBO that I need something to keep me busy 
now that I'm semi-retired, I almost have her convinced that my building 
a K2 would do it, but I noticed that the pricing lasts until Jan 31st.?? 
Are you thinking about a Valentine's Day sale too ???

I am a pilot rather than a sailor, but I wonder if the two knots means net speed with respect to position, which could mean almost any speed with respect to the flow of water past the hull.  Like the difference between air speed and ground speed?  An airplane with an airspeed of 100 knots into a direct headwind of 98 knots - God forbid - would have a ground speed of two.

Or don't sailors talk that way?

Up and Down, Up and down, Up and down if the seas are really rough could
slow things down a little.  You are no longer going in a direct line like
you would in smooth seas.

Hi Ted, Indeed sailors to talk that way. As with an airplane there are multiple factors at work which affect SOG in a sailboat. The hull speed can be different than SOG.

Hi-

I need to get as much Mic. gain as I can with the current Mic. I have had no need to adjust it for 15 years until now as I use CW. 

My manual is not available.

Can someone give me a lesson in Mic. gain adjustment??

Thanks, Dave  K1OPQ

I developed a simple mod that adds about 6 dB and adds some low 
frequency rolloff. I don't recall details (that was 15 years ago), but I 
think W3FPR has notes on it somewhere. It involves changing a few 
resistors and one or two caps in the audio chain. I recall that there 
other mods farther up the chain.

All,

I do indeed have that mod, but I thought it was mainly for Low Frequency 
rolloff.  I do know that it works quite well for that purpose, but I 
don't know about the 6 dB gain.

Change C34 to 0.47uF, and change C32 to something in the range of 
0.003uF to 0.005uF.

If you want additional gain, I would recommend the KI6WX KSB2 increased 
KSB2 RF Gain mod.  It adds gain without the possibility of overloading 
the Speech Compressor.  If you do that mod, change R9 to 15k and add a 
1k resistor between P1 pin 5 and the base of Q3.

All,

On the KI6WX mod, the value of R9 should be 1.5k instead of 15k as 
stated. Please excuse my "late night fingers".

Those two resistor changes are only necessary if the KI6WX KSB2 mod is 
added to a K2 with the KPA100 installed.

If you enjoy kit building, the K2 goes together one part at a time, just 
like any other kit.  Enjoy the process.

The K2 breaks the assembly into 3 major pieces and has an alignment and 
test section following each assembly section so you can check your work.

 I am driving my KPA500 with my K3 to a Mosley PRO 67. On every band except 20 meters 25 watts out from the K3 will give me at least 500 watts out of the amplifier. On 20 meters I get 450 watts out with 25 watts drive but no increase even if I go to 40 watts out from the? K3. I have put a dummy load on the K3 using the usual RG 213 and the SWR is 1:1, and I have checked the antenna with an MFJ 259, using the usual RG 213 cable and it is 1:1 at 14.000 up to 1.4:1 at 14.350.I have loaded the latest firmware to both the K3 and the KPA. I realize that the difference between 450 and 500 watts is negligible but it bugs me that it is not giving me full power out on 20.Anyone have any ideas as to how to fix it?Many thanks, Mike, WM5DX.

Tom,
     I can't explain the cause of what's happening. Rob and I ran into 
some craziness last weekend with power out and the antenna tuner. We 
fixed the symptom, but have been unable to trace the cause. In my case, 
I'm willing to swear that RF got in and corrupted the matrix of L and C 
values stored in the radio's memory, but I can't reproduce the symptom. 
What Rob suggested was to store off the radio settings using the 
utility, doing a reset, and put the setting back. That seems to have 
fixed the problem, so far. What is crazy is that of the set of K3 owners 
around us, only Rob and I seem to have had a problem. In the about 2 
years I've used my K3s, there has never been a hint of anything like 
this.

My amp is close to 7 years old and 20 has always required more drive.? 
27 to 30 watts on all bands except 20 where I'll run it up to 35 in a 
pinch. Elecraft suggested I send it in, but I haven't let the smoke out, 
yet.? Unlike your issue, I see a change when I increase drive. I drive 
the amp with either a Yaesu FT-950 or a FTDX3K.? ALC is not wired.? 
There is a modification kit out for the amp, but have no idea what it 
addresses.

Also, heat causes some stress on the chassis and you'll here pings as it 
flexes with temp.? The first time I heard that, it scared the heck out 
of me.? I believe there is a fix for that, too.

Slowly, ever so slowly over the years, I shifted from QRP CW, mostly with
the K2, to 100w SSB, with the K3 and a couple of other rigs, operating only
on a couple of SSB nets.
And then I read Wayne's post.  And the responses.
And looked at the K2 on the desk, connected but unused, gathering dust.
So last night I fired it up, in these poor propagation days, and running CW
on 40m at just under 5w on the meter into an inverted V, snagged AE4YP in
FL, K3Y/1 in NH, and shortly after, K3Y/0 in CO.  This morning I heard
K3Y/9 - very weak - but he did not copy me, and I refused to turn up the
power.

Thanks, Wayne.

I have always referred to it as "Thermalize".
Have you tried that in a google search?

Subject: [Elecraft] Lease a KPA1500?
Message-ID: <92474D31-E917-4699-922E-08B35FA79132@contoso.com>

This an informal, nonscientific survey:  Would there be any interest in leasing rather than buying a KPA1500?  The full price of the amp is $6K, which with sales taxes and shipping, if applicable, would bring it to $6.5K or so.  Not everyone wants to plunk that much down all at once.  So I was thinking ? suppose a lessor (?owner? is easier) bought the amp and leased it to the lessee (the ?user?) for a monthly rate.  At the end of the lease term it would either be returned or purchased for the buyout price, much like a car lease.

Do you think there would be any interest in such a deal?  What monthly fee would seem fair and saleable?

I have begun thinking about the terms of the deal.  The amp would be shipped directly from Elecraft to the user, so it never comes to the owner.  Any problems on delivery the user works out with Elecraft.  Mods, if any, during the lease would be factory installed, or not installed, and the cost shared.  In short, the user never opens the chassis.  Likewise for repairs, if any.   Repairs made necessary solely by the user?s out-of-spec actions are done by Elecraft at the user?s cost.  Insurance coverage, maybe through ARRL, for lightning and the like would be in place.  At the end of the lease, if the amp is returned to the owner, it goes first to Elecraft for an inspection and tune up, at shared cost.

Years ago a partner and I had a sideline business of leasing general aviation aircraft, so I do have some tolerance for risk.  Fortunately, we never had a loss.  But I don?t know how much leasing demand there might be out there for a full legal limit Elecraft amp , or at what price.  Any thoughts at all would be very much appreciated.

Thanks,

Ted, KN1CBR

Thermaleze wire is what I think y'all are talking about.
Amidon has some...
Finding good wire of known origin/specs in the required quantity at a reasonable price is quite the challenge.

Hi Thaire,
The 6Gs DXpeditions (TX6G, E6GG, ZL7G + later this year VK9X(full call TBD))
have all included 12m and/or 18m Spiderpoles as antenna supports.  We wrap
them in bubble wrap and ship them in ski bags or hard ski/snowboard cases as
checked baggage.  No issues with breakage or loss, but we have had to
describe them as 'fishing poles' a couple of times.
If you want to have your antenna support as carry-on baggage, you'll usually
need to keep it to a collapsed length of 1.2m (4ft) or less.  For that the
DX-Wire poles are ideal (available from
http://www.dx-wire.de/lng/en/fiberglass-poles/?xploidID=156c8060417ce6049df949b4569517dc
or from SOTABeams)
HTH.
Enjoy the trip!

Not a problem Mike. It is radio related.
 You might fill us in on where you got it and cost. It looks like a nice QRP kit to build.
Can you give us details on power out etc.?
It would be an interesting poll to see how many on the reflector know who Agent 86 is and who the girl is in the photograph. HI

Thanks, guys, for understanding - and being interested.

It is a fun kit to build and is from Four States QRP Group, 
http://www.4sqrp.com .  This a regenerative design based on the famous 
Paraset and Atlantic Hopper, which Four States calls the Bayou Hopper.

I had my first qso on it yesterday and it really takes a bit of a fine 
touch to continually tune with one hand while the op is transmitting. 
But it's all part of the fun!  It puts out about 5 W to 6 W.

And then Agent 99...  :-D

While attempting to get Z60A on 40M last night I ran into a problem that I never encountered before.


My KX2 has the built in auto ATU. I took the output from the rig into a QRP SWR/PWR bridge and then into my 40M EDZ and hit the "ATU" on the rig. "Click, Buzz" and the rig came up with a 1.0-1 SWR reading. HOWEVER, my QRP bridge was pegged in reverse indicating that there was no match.


Earlier I had tried this set up on my 20M Yagi and it worked great. The rig gave me 1.0-1 and the analog meters on the QRP bridge did the same.


The only thing I can think of is the 40M EDZ is the problem. I am going to try removing the QRP bridge and see if that makes a difference.


In the mean time, anyone have a guess as to what I am seeing on 40M??

Rich:

May be a dumb question but is your SWR bridge between the ATU and the
antenna? If so, it is not going to give you any useful information.

internationally.  It's only 27 inches and fits in a big suitcase.  Never a
question., but I do pack it where it can be found immediately.  I expect
you could take it as carry-on, too, but why?

The Zepp is not 50R.  The Yagi is.  Both SWR meters are likely telling you
the truth.

While attempting to get Z60A on 40M last night I ran into a problem that I
never encountered before.


My KX2 has the built in auto ATU. I took the output from the rig into a QRP
SWR/PWR bridge and then into my 40M EDZ and hit the "ATU" on the rig.
"Click, Buzz" and the rig came up with a 1.0-1 SWR reading. HOWEVER, my QRP
bridge was pegged in reverse indicating that there was no match.


Earlier I had tried this set up on my 20M Yagi and it worked great. The rig
gave me 1.0-1 and the analog meters on the QRP bridge did the same.


The only thing I can think of is the 40M EDZ is the problem. I am going to
try removing the QRP bridge and see if that makes a difference.


In the mean time, anyone have a guess as to what I am seeing on 40M??

Rich,

As you describe your configuration, your SWR bridge is between your KX2 
and the antenna.? The matching that takes place is within your KX2, and 
apparently, the ATU was able to achieve a match. That doesn't change 
what was happening on the transmission line from the antenna to your SWR 
bridge, it is what is is and always was.

No "antenna tuner" in the history of humankind has ever "tuned" an 
antenna.? It's a really unfortunate choice of nomenclature.? The ATU in 
your KX2 transformed the impedance it saw at the antenna connector to 
something the PA stage was happy with.? That's all. Nothing changed on 
the transmission line from the antenna as evidenced by your SWR Bridge's 
report.

That very high SWR on your transmission line could be anything from a 
"Not To Worry" to a "Very High Loss" situation.? You didn't say what 
your transmission line is, EDZ antennas are often fed with some form of 
open-wire line.? If so for you, losses are likely low.? If it's fed with 
coax, maybe not so much.? If you make Q's, it's working, that's why it's 
called "Amateur Radio." [:-)

Rich,

I assume you are using the internal ATU.  If so, the external wattmeter 
will not change - it will show the SWR into the antenna, and not at the 
input to the internal ATU.

An ATU does not change the antenna SWR, it only adds L and C in a 
combination that will make the PA transistors in the transmitter 'happy' 
which allows maximum power output.

as Eric said the K2 is still in production. It is the best multiband KIT on
the market with better K-parameters than several much more expensive
commercials on the market, hi.

BTW - did you realized how the price of used K1 rise-up on the market :)

Subject: [Elecraft] KX3 Roofing Filter Question
Message-ID: <765520bb.1faf0.16143ca985b.Webtop.39@optonline.net>

I am going to order another KX3 this week. Probably tomorrow.? The last 
one I ordered in 2012 did not have the roofing filter option and I do 
not THINK I missed it.

I use ONLY CW and I do NOT contest.? I like to CASUALLY chase DX and I 
play in low stress sprints like NAQCC but mostly I just like to RAG 
CHEW.


My antenna is an EFHW installed as a "half square" in trees at 30 feet 
(MyAntennas 4010).


I have reviewed the Elecraft site notes, and done a fair amount of 
Googling and I now am more confused than ever.? It seems that the real 
value lies in dealing with strong signals, crowded bands and ferocious 
contesting conditions.


My bottom line question is this:? If I DO NOT get the roofing filter 
option will my KX3 receiver be LESS SENSITIVE?? The Sherwood report 
shows a pre-amp off sensitivity of .9 uv which improves to a very 
impressive .09 with the preamp on.? Is this somehow related to the 
roofing filter?


I am especially concerned because I remember doing an A/B comparison on 
a weak signal between my previous KX3 and my 55 year old Drake 2B and 
the 2B beat the crap out of the factory built KX3.? I can't help 
wondering if the roofing filter I didn't buy in 2012 had something to do 
with this.


I sure could use a real simple answer:? buy it or don't buy it?? CW 
sensitivity is my ultimate goal because if I can't hear 'em I can't work 
'em.


Thanks and 73,
Stan WB2LQF

Stan,

I am not going to give you a terse answer, but I can say that the 
sensitivity of the KX3 does not depend on the roofing filter.

However, the roofing filter will give you more rejection of unwanted 
signals that you may encounter in crowded band conditions.

If you do not operate when the bands get crowded, you will not notice 
the difference with or without the roofing filter option.

If you do choose the roofing filter, be certain you do the calibration 
if it is a kit.  If you order the factory built KX3 with the roofing 
filter option, that calibration will have been done at the factory.

73,
Don W3FPR

My kit build KX3 instruction manual says that I don't have to do the calibration if I ordered the filters WITH my KX3 kit:

"If you received the optional KXFL3 filter with your kit, you do not need to perform theReceiver Sideband alignment procedure referenced in the Owner?s manual and describedin detail in the KXFL3 option manual. That procedure was done for you at the factory."

That was back in 2013, so maybe things have changed.?

Mark,

I took 10 years to build my serial #1xxx K2 kit. I started the kit in about
'99 and put it aside when we had an addition being built. Over the years, I
recorded and kept tract of all the mods and updated parts. I ordered and set
aside crystals, firmware (didn't even use one of the chip sets) and other
mod kits. I edited the assembly instructions as time went along and in about
2010, I got the kit and parts out, refreshed my understanding of the
assembly and inserting mods, etc, and finished it in about a week or so. And
it worked perfectly. I have had opportunities to sell it, but somehow it
seems like an old friend.

Epilog:  Today, I replaced both BAS70 Schottky diodes (D36/D37) and now the K3 SWR readings are stable and the internal ALC is working as expected.  At this time, it appears diode failure was caused by antenna static.

A suggestion to those who may run into this problem in the future:  it turns out that D36 and D37 are easily accessible by removing only the bottom rear plate.   Access could not be easier.  The diodes are SMT/SMD and so great care must be exercised in the rework process.  

What should have taken me less than 30 minutes turned into several hours.  I had convinced myself that the diodes were either on the PA module or KAT3 and so I had disassembled much of the K3.  The K3 block diagram doesn?t show a module where the SWR bridge resides.  The schematic indicates "K3 RF Board," but that's not the PA module.  The RF Board is actually the flat motherboard that the PA module and KAT3 plug into.  Once that detail was figured out, I reassembled the K3, leaving only the bottom plate open for the repair.

Highly unlikely.  Clear skies for days.  No lightning activity here in a long time here.  Two years ago, I had a similar problem with static-damaged Schottky diodes in an Alpha 9500.  Those diodes are used to sample RF for the amp's EBS circuit.  

>"I strongly urge everyone to use protection devices on all 
coax and balanced lines at the point where the feed lines and rotor 
lines enter the house.  I prefer Polyphaser devices."

Already installed and we never disconnect at the remote site.  The site conforms to Motorola R56.  No lightning-induced damage in almost 3 years of operation in a very lightning-intense location near the Okefenokee Swamp.   High power Alpha-Delta arc-plug devices are located at the master ground bus where all coaxial and control lines enter the station.  Low power (200W) Alpha-Delta devices are installed between the K3 and amplifiers.  The Alpha-Delta devices use field-replaceable arc-plugs.  Like Polyphaser, these devices are intended to mitigate lightning-induced charge, not necessarily antenna static charge.  Still, it's possible that one or more of the Alpha-Delta arc plugs has failed, leaving the K3 vulnerable to static damage. 

In looking at the K3 SWR bridge circuit, both sides of the Schottky diodes have a reasonably low impedance to chassis ground.  One side is slightly less than 22K-ohm.  However, it may not be low enough. To supplement protection, I may add a pi-section 1 mH choke between T3 and the chassis.  It's the same choke used as a static drain in the Alpha 89 and 87A amplifiers to prevent static-induced PIN diode damage, and the type used at the output of many vacuum tube amps to function as a safety device in the event a plate blocking capacitor fails in a shorted condition that would otherwise allow high-voltage on the output network, transmission line, and antenna.

Although fun to discuss and contemplate fixes, it's conjecture until validated and the root-cause may not be related to any of this.

Thanks Bob and all the others who responded.


I figured that the KX2 internal ATU and SWR/PWR meter was giving me the "match" between the 50 ohm of the rig and the QRP SWR/PWR meter and that I had a problem with the 40M EDZ which has been up for over 9 years.


I removed the QRP meter from the equation and the KX2 ATU gave me a 1.2-1 match on the EDZ, at which time I went out to the tower and checked the balun on the end of the 450 ohm window line. While it was hooked up correctly and there were no broken wires, when I looked at the feed point on the mast on the roof it looked like one of the feed line wires was either broken or otherwise hanging out in mid air. Now at least I have a probable cause for the strange RF readings.


Since it is pretty nice weather here in my area I am planning on shooting a line into one of the 100 ft trees on the edge of our property and string up an end fed wire of some non-resonant length and use this until I can get some local club members together and replace the entire 40M EDZ and hang it on the tower at about 60-65 ft! Oh, there will be a counterpoise on the end fed wire!


Has anyone on this group ever modeled a long, non-resonant end fed wire w/counterpoise that can give me some idea of how directional they are (or aren't)?  I need to get a copy of EL-NEC!

The ATU in the KX2 does not change the SWR on the feedline.   So your
QRP SDR/PWR meter, which is after the KX2 ATU, is showing the SWR on the
feedline.   The KX2 is showing the SWR between the PA stage in the radio
and the input to the ATU.

As to 20M.  Likely your match is good with or without the ATU thus the
external meter is showing the SWR on the feedline.

Nothing wrong except you need to work on that 40M antenna and improve
the SWR to a respectable value.

WRT carry-on baggage make sure you check with the airline AND with the airport's restrictions as well.

Last year I carried-on a camera tripod that was 35" in total length in a softcase. On my return trip the Vietnamese version of 'TSA' would not allow me to take it as carry-on stating it was too long and showed me a newly written reg. stating max length of a tripod is 30". The airlines are a good start, but sometimes don't have the most up-to-date info.

Hi Thaire,
The 6Gs DXpeditions (TX6G, E6GG, ZL7G + later this year VK9X(full call TBD)) have all included 12m and/or 18m Spiderpoles as antenna supports.  We wrap them in bubble wrap and ship them in ski bags or hard ski/snowboard cases as checked baggage.  No issues with breakage or loss, but we have had to describe them as 'fishing poles' a couple of times.
If you want to have your antenna support as carry-on baggage, you'll usually need to keep it to a collapsed length of 1.2m (4ft) or less.  For that the DX-Wire poles are ideal (available from http://www.dx-wire.de/lng/en/fiberglass-poles/?xploidID=156c8060417ce6049df949b4569517dc
or from SOTABeams)

Enjoy the trip!

however, if you get updates on K2 orders, you'll see that SWMBO thought 
it was a VERY good idea that I be kept out of her ha... er busy.?? So, a 
K2 with all the bells & whistles will be making its way to me in the

Subject: [Elecraft] Wrong PIM nuts in KPA500 kit
Message-ID: <f4588985-7db7-445d-9005-bd3da81bd7ef@me.com>

I received a call back from Elecraft Technical Support yesterday.? It was quite difficult to come together on exactly which screws and embedded PEM nuts I was talking about in the bottom cover.? Once we were in agreement on the screw positions I was talking about the technician looked at a bottom cover but was unable to determine the exact thread sizes as he was unwilling to remove the green protective tape which covered the holes.? He was not really equipped to handle this mechanical sheet metal problem but was going to refer it to another group which could more easily address the problem.? I initially got the impression that he thought that I was incorrect about the threaded nut (PEM nuts)? error but I think we got past that.

For clarification, if you have a new kit and would check, these are the steps where the problems arise:

These are the steps in the Kit Assembly Instructions

Page 15, figure 14 show six (6) 1/4" 6-32 BLACK FLAT HEAD SCREWS. The right hand two (2) 6-32 screw locations were equipped with 4-40 threaded nut inserts (PEM nuts) rather than the correct 6-32 threaded inserts (PEM nuts).? The two (2) 4-40 BLACK FLAT HEAD SCREW shown in this figure were correctly equipped with 4-40 threaded inserts (PEM nuts).

The same problem exists on the right hand side cover.

Page 24, figure 32 instructs you to install four (4) 6-32 BLACK FLAT HEAD SCREWS.? In this case the two rear 6-32 screw locations were equipped with the correct 6-32 threaded inserts (PEM? nuts) but the front two locations were equipped with 4-40 threaded inserts (PEM nuts).

At this point I am waiting to see what they find when they check their current supply of bottom covers and what their recommendation will be to correct the problem.

I do have a photo but I do not believe I can attach it to the reflector.

I am waiting on a response from Elecraft TS on this one but I thought I would ask if anyone else has encountered this problem on the KPA500 kit.

On the bottom edge of both the right and left side panels there are places for three 6-32 flat head screws. The countersunk holes are obviously larger than those for the other 4-40 flat head screws.

In my kit one of the three PIM nuts, for each side, was the correct 6-32 thread PIM nut and the remaining two had 4-40 PIM nuts installed in the bottom cover. When I had temporarily installed the left hand side panel in the middle of construction I failed to notice this and just installed screws that fit (one 6-32 and two 4-40) but during final assembly it became obvious that the 6-32 screws would not fit in 4 of the 6 positions.

Thinking that they just had paint in them I tried tp run a 6-32 tap through one and it naturally seized up and twisted the PIM nut out. Not being the brightest bulb in the shop I tried that a second time and twisted out the second PIM nut.

Fortunately these were both on the right hand side where there was room to slip two 6-32 hex nuts in place and I just used two 4-40 flat head screws on the left side.

Hopefully Elecraft will be able to send me the correct PIM nuts to replace the four incorrect ones. That was my request in the email to Doug at tech support.

I certainly would not want to replace the bottom coverl as that would require a complete disassembly of the amplifier.

Has anyone else encountered this?

My k3s occasionally does this too. I finally isolated the problem 
initiator as a burst of very loud signals, such as occurs when listening 
to a very weak DX station when a very strong (speaker rattling) station 
plops on top of him followed by the loud frequency cops. The Sub Rx must 
be is on and the volume for Main Rx is cranked up for the weak station. 
A single loud signal does not appear to initiate the SPKRS parameter 
change. It appears to only happen with multiple loud signals in the 
passband. These signals will be loud enough that I turn down the volume 
very quickly. During this loud outburst, the SPKR config will change to 
"1". I have set up a macro button to toggle the SPKRS configuration so 
that I can quickly return it to "2". If I turn the volume down a bit, it 
doesn't do this so I'm wondering if there's some "safety" mechanism 
built into the audio driver control circuit/firmware. Is it due to 
mixing of close frequency audio signals in a non-linear audio amp 
(clipping mode) producing sub-audible products? I don't know, it's just 
a thought. It's only an occasional annoyance for me so I've never 
pursued a cure.

My AF LIM parameter is currently set at 30 but I seldom have AGC off. It 
does it with AF GAIN "HI" or "LO" but if the gain is set "LO", I must 
turn the volume knob up more to compensate so I end up listening at the 
same relative audio levels. I'm running LP Bridge and at least one 
logging program and a K-Pod but have no other macros that directly deal 
with the SPKRS parameters. My sub Rx card is an older version retrieved 
from my original K3.

A cure or a work-around would be nice,

Mike, AB9V

Yes.  I've noticed that as well, in that it occurred when a loud signal popped into the passband!  My AGC is always on with the affected K3.

That makes two of us.

So I now suspect that there is a common menu setting or front panel setting or firmware setting that is causing this.  I was afraid my vintage K3 was dying!

Subject: Re: [Elecraft] K3 Switches Number of Speakers

My k3s occasionally does this too. I finally isolated the problem
initiator as a burst of very loud signals, such as occurs when listening
to a very weak DX station when a very strong (speaker rattling) station
plops on top of him followed by the loud frequency cops. The Sub Rx must
be is on and the volume for Main Rx is cranked up for the weak station.
A single loud signal does not appear to initiate the SPKRS parameter
change. It appears to only happen with multiple loud signals in the
passband. These signals will be loud enough that I turn down the volume
very quickly. During this loud outburst, the SPKR config will change to
"1". I have set up a macro button to toggle the SPKRS configuration so
that I can quickly return it to "2". If I turn the volume down a bit, it
doesn't do this so I'm wondering if there's some "safety" mechanism
built into the audio driver control circuit/firmware. Is it due to
mixing of close frequency audio signals in a non-linear audio amp
(clipping mode) producing sub-audible products? I don't know, it's just
a thought. It's only an occasional annoyance for me so I've never
pursued a cure.

My AF LIM parameter is currently set at 30 but I seldom have AGC off. It
does it with AF GAIN "HI" or "LO" but if the gain is set "LO", I must
turn the volume knob up more to compensate so I end up listening at the
same relative audio levels. I'm running LP Bridge and at least one
logging program and a K-Pod but have no other macros that directly deal
with the SPKRS parameters. My sub Rx card is an older version retrieved
from my original K3.

A cure or a work-around would be nice,

Mike, AB9V

I noticed that during the contest, that if I selected 50 or 100 Hz selectivity, 
the audio would drop way down. It didn't used to be this way. I tried reloading
an earlier version of the software but couldn't figure out how to do it.

Hope this comes through, finally!

If you are interested in building as well as operating it's a pleasant
experience. Just like a 10 mile hike, you do it one simple, easy step at a
time. 

Those who seem to have had trouble just wanted a K2 to operate and tried to
put the kit together as quickly as possible without double-checking their
work at each step along the way.

Beyond that, the manuals are VERY detailed and for most part as complete as one could expect, HOWEVER, the builder needs to have the mental attitude to take a step back and think like you are just starting and reread and recheck every step. When you do, it IS a very rewarding experience and LOTS of FUN.

Subject: [Elecraft] KX3 Faulty SWR indication
Message-ID: <CAKynJK=yi4JEi2Fa8nv0BLEOxQxA4835Rpx8ch6CiBdQJxk4Fw@mail.gmail.com>

A few weeks ago I posted this problem, worked on it a bit, then got
distracted into other projects.  I am now back trying to resolve the faulty
SWR issue with My KX3.  The problem only occurs on 160, 80 and 60 meters.

Using a known good dummy load and cable the indicated SWR on the KX3 is
high --- 1.8 to one using 10 watts.  An external wattmeter/SWR meter shows
the Dummy Load as a perfect load.  The reflected power needle does not move.

I have done repeated Power Out Calibrations with the KXPA100 (not relevant,
I know).  The KX3 shows the same faulty SWR Readings with or without the
KXPA100.  Of course the ATU mode is in bypass.  But, when the ATU is
active, it matches, shows a proper SWR briefly, then shows the faulty
reading as the rig transmits.

It was a factory built unit S/N 4932.

I'm stumped.  I guess it is time to send it home for healing.

Based on your description, I'd say there is some instability in one of 
the stages.?? The dummy load will present a uniform impedance at all 
frequencies, thus the SWR will be 1:1.?? output network will show 
evidence of reflected power.?? Using the ATU, it adds filtering thus

The funny SWR also appears with the ATU in circuit but not at the tuning PWR level.  It appears when the rig is in "normal" transmit mode after tuning.  Bob is likely right though - try turning the power down and see if results in "normal" operation.  You may find it power dependent - if so it could be very hard to fix unless you're experienced and willing to solder and unsolder parts.

I think that building the K2 has to be an end in itself. I have more 
pictures of various pieces taped to colored construction paper than I do 
of the radio itself. Other pictures feature my method of winding 
toroids.  Then, at the end of building, you step over the "building 
finish line" to discover that you own one of the really great radios in 
the history of amateur radio. Then the operating fun begins.

Message-ID: <9121112ef91a0a334ff660307eb3aac6.squirrel@www11.qth.com>

You can install PEM nuts with a hammer and anvil but it's best to do it
with a PEM insertion machine or a fixture in a press. 4-40 nuts typically
require a .166 diameter hole and 6-32 require a .188 hole.

On the bottom edge of both the right and left side panels there are places
for three 6-32 flat head screws.  The countersunk holes are obviously
larger than those for the other 4-40 flat head screws.

In my kit one of the three PIM nuts, for each side, was the correct 6-32
thread PIM nut and the remaining two had 4-40 PIM nuts installed in the
bottom cover.  When I had temporarily installed the left hand side panel
in the middle of construction I failed to notice this and just installed
screws that fit (one 6-32 and two 4-40) but during final assembly it
became obvious that the 6-32 screws would not fit in 4 of the 6 positions.

Thinking that they just had paint in them I tried tp run a 6-32 tap
through one and it naturally seized up and twisted the PIM nut out.  Not
being the brightest bulb in the shop I tried that a second time and
twisted out the second PIM nut.

Fortunately these were both on the right hand side where there was room to
slip two 6-32 hex nuts in place and I just used two 4-40 flat head screws
on the left side.

Hopefully Elecraft will be able to send me the correct PIM nuts to replace
the four incorrect ones.  That was my request in the email to Doug at tech
support.

I certainly would not want to replace the bottom coverl as that would
require a complete disassembly of the amplifier.

Has anyone else encountered this?

Hi Noel,

No, you don't have to tie those together unless the software you are using needs them for some sort of flow control handshaking, but that too, would be unusual because back in the days of modem RTS (Request to Send) and CTS (clear to send) were used by the modem to let the terminal (your computer) know it was ok for it to send data.  DTR (Data Terminal Ready) was a handshaking signal from the data terminal (computer) to let the modem know it was OK to send data to the terminal. Handshaking flow control is not used these days and so that is why RTS and DTR are often used by logger programs for CW and PTT.  The K3 allows this because its serial port implements them.  The KX3 can't because its serial port is only for data (TxD and RxD).

(An exception that I seem to remember is that some Kenwood radios needed RTS and CTS jumpered on the radio side.)


Cheers,

Fred KE7X

The vast majority of laptop computers come with a little 2mmx7mm slot in
the case to allow the attachment of a security cable to discourage them
from growing legs when left unattended for a few minutes... Is there a spot
on the case of a K3s where such a milled slot could be added? It would be a
help when using one in a public place like Field Day, etc.

I just received a response from Elecraft. They are sending me a new bottom cover and a noise kit for some transformer noise that I had not previously mentioned here. While this will involve me tearing down the amplifier and then rebuilding it the outcome will be a properly constructed amplifier. 

In all fairness they did offer to repair it at Elecraft but I declined because of shipping and insurance cost and not having appropriate packing since it was a kit. 

It was a good response I think.  Thank you Elecraft.

Let the rumors / guess's begin on what will be announced at Dayton/Xenia.

Maybe an External/remote antenna tuner that can be mounted outdoors that 
communicates with a? K3(s) or KX3 and follows along like the 
K3(s)/KAT-500 does.? Two versions, 500 watt and 1500 watt so it can 
handle a KPA-500 or KPA-1500.? It also needs to be able to handle coax 
as well as open line.

I took 10 years to build my serial #1xxx K2 kit. I started the kit in about
'99 and put it aside when we had an addition being built. Over the years, I
recorded and kept tract of all the mods and updated parts. I ordered and set
aside crystals, firmware (didn't even use one of the chip sets) and other
mod kits. I edited the assembly instructions as time went along and in about
2010, I got the kit and parts out, refreshed my understanding of the
assembly and inserting mods, etc, and finished it in about a week or so. And
it worked perfectly. I have had opportunities to sell it, but somehow it
seems like an old friend.

I use Tryten T3 cables. The T3 has a very strong glue to connect a hardened cable pass-through to a device without its own security slot. 

These cables and holders are made for server racks that need to he held more securely than a cable lock. Note the kit also contains some wedges to fit into a cable slot too to connect to the monitor. Of course, this is not to keep it safe from someone that has their tools and a good amount of time from getting the item. It does discourage quick grabs and other crimes of opportunity.

Here is a link: https://www.tryten.com/cable-locks/universal-computer-lock-kit-standard-t3.html

The small black block can be glued to a radio with the supplied glue. As I said, some one could take their tools and disassemble the radio but not in the few minutes you left it unattended I suspect.

Message-ID: <1828962906.3109799.1517262312940@mail.yahoo.com>

When plucking a particular station out on FT8, something that would be useful in the increasingly crowded segment conditions would be to have the radio's filters narrow the passband to just a particular width at a particular frequency (and then go back to a much wider bandwidth at particular times).

I see that the IS and FW (or BW, recommended by the K3 programmer's manual) can do this -- has anyone developed a macro like this for this application?

Example: FT8 on 20m uses the dial frequency of 14074.00, USB. If I'm trying to hear a station at 1800Hz, I'd like to narrow my RX passband to be between 14075.77 and 14076.10 (ft8 bw is 50Hz). But also want to go back to a 2.4 kHz bandwidth.? I might also want to transmit outside the parameters of my RX passband, e.g. in this example, I might transmit tones from 800-850 Hz.

I took 10 years to build my serial #1xxx K2 kit. I started the kit in about
'99 and put it aside when we had an addition being built. Over the years, I
recorded and kept tract of all the mods and updated parts. I ordered and set
aside crystals, firmware (didn't even use one of the chip sets) and other
mod kits. I edited the assembly instructions as time went along and in about
2010, I got the kit and parts out, refreshed my understand of the assembly
and inserting mods, etc, and finished it in about a week or so. And it
worked perfectly. I have had opportunities to sell it, but somehow it seems
like an old friend.

Subject: [Elecraft]  Wrong PIM nuts in KPA500 kit
Message-ID: <004801d39a40$e7da1550$b78e3ff0$@com>

A 4-40 PEM nut typically requires a .166 diameter hole and a 6-32 requires a
.188 hole. So if a 4-40 nut was installed in a.188 hole it will not grip the
material properly and it will eventually fall out. You should not re-tap the
threads to correct the problem or use a smaller screw. You can install PEM
fasteners with a hammer and anvil however there are insertion machines
designed for this task.

I received a call back from Elecraft Technical Support yesterday.  It was
quite difficult to come together on exactly which screws and embedded PEM

bottom cover but was unable to determine the exact thread sizes as he was

For clarification, if you have a new kit and would check, these are the
steps where the problems arise:

These are the steps in the Kit Assembly Instructions

Page 15, figure 14 show six (6) 1/4" 6-32 BLACK FLAT HEAD SCREWS. The
right hand two (2) 6-32 screw locations were equipped with 4-40 threaded
nut inserts (PEM nuts) rather than the correct 6-32 threaded inserts (PEM
nuts).  The two (2) 4-40 BLACK FLAT HEAD SCREW shown in this figure were
correctly equipped with 4-40 threaded inserts (PEM nuts).

The same problem exists on the right hand side cover.

Page 24, figure 32 instructs you to install four (4) 6-32 BLACK FLAT HEAD
SCREWS.  In this case the two rear 6-32 screw locations were equipped with
the correct 6-32 threaded inserts (PEM  nuts) but the front two locations
were equipped with 4-40 threaded inserts (PEM nuts).

At this point I am waiting to see what they find when they check their
current supply of bottom covers and what their recommendation will be to
correct the problem.

I do have a photo but I do not believe I can attach it to the reflector.

On the bottom edge of both the right and left side panels there are places

larger than those for the other 4-40 flat head screws.

In my kit one of the three PIM nuts, for each side, was the correct 6-32
thread PIM nut and the remaining two had 4-40 PIM nuts installed in the
bottom cover. When I had temporarily installed the left hand side panel in
the middle of construction I failed to notice this and just installed
screws that fit (one 6-32 and two 4-40) but during final assembly it
became obvious that the 6-32 screws would not fit in 4 of the 6 positions.

Thinking that they just had paint in them I tried tp run a 6-32 tap
through one and it naturally seized up and twisted the PIM nut out. Not
being the brightest bulb in the shop I tried that a second time and
twisted out the second PIM nut.

Fortunately these were both on the right hand side where there was room to
slip two 6-32 hex nuts in place and I just used two 4-40 flat head screws
on the left side.

Hopefully Elecraft will be able to send me the correct PIM nuts to replace
the four incorrect ones. That was my request in the email to Doug at tech
support.

I certainly would not want to replace the bottom coverl as that would
require a complete disassembly of the amplifier.

Has anyone else encountered this?

In general, filters have little to do with sensitivity.?? On the other 
hand, filters do provide selectivity.?? In crowded band conditions where 
one is attempting to dig out a weak signal among stronger signals, the 
roofing reduces the likelihood that the stronger signal will impact the 
overall AGC, thus diminishing the apparent strength of the weaker signal.

Otherwise, the added roofing filter certainly can't diminish the 
receiver performance but may, under certain conditions, enhance receiver 
performance.

Conclusion:?? buy it!

Stan,
If you use the 8 KHz receive offset, you can not use the roofing filter; 
it is disables when you invoke the SHFT. So, having it will do you no 
good. And, that's the simple answer.

I have my KX3 set to the offset as it cleans up the spectrum display 
that I use; I've never looked into the performance difference of using 
the offset or not. I did use my KX3 for causal DX, contesting, and 
everything in between. It's a wonderful radio. I have since purchased a 
K3s, so the KX3 has been relegated to Field Day use only.

Be careful of system sensitivity specs. Most receivers are more 
sensitive than ambient conditions will allow. The .9 uV number you show 
is absolutely fine for the lower end of HF, but you could use a little 
more at the upper end. I live in an urban environment with power lines 
and neighbors with noisy TVs, heat pumps, and solar arrays. I'd be more 
than happy if I could use a sensitivity of a 1 uV on 80.

73,
Barry

Subject: [Elecraft] KX3 Power cable
Message-ID: <CAKynJKnN-3+psuJ17+SRHxvsma1FR95VcKx8gtv65PE_mwgKNQ@mail.gmail.com>

Good morning,

I am using the standard power cable that is supplied with the KX3.  Using a
digital multi meter and the built in voltage monitoring capability of the
KX3, it looks like the supply voltage is dropped by 0.5 volts in the power
cord when transmitting with 5 watts  According to the built in monitor, the
KX3 is pulling 1.6 amps from my gel cell.

The gel cell voltage drops also, but I compensated for that when I
calculated the .5 volt drop in the power cord.

It seems to me that a larger gauge wire is called for in the power cord.

Also, I can't get the KX3 to transmit more than 5 watts.  If I turn the
power up to 10 watts, it transmits at that level briefly, then turns the
power down to 5 watts.  It must be some voltage sensing circuit that does
it.  The supply voltage is showing 11.4 VDC when keyed..

So what about the gauge of wire for the power cord?  Do you think we need a
larger sized wire?

73,

Dave, K4TO

When it switches number of speakers, it is not connected to anything except my Yaesu Quadra amp thru the ACC port and an antenna.  I also have the Elecraft K-POD connected.  Non of the Macros in the K-POD deal with the spkrs.


It started switching spkrs about 6 months ago.  Today, when I was resetting the number of spkrs from 1 to 2 while in the menu system, it would automatically go back to 1 when I dialed in 2 and do that a couple of times before it stopped and I could enter the selection by pressing the MENU button again.

My old K3 occasionally switches from 2 speakers to 1 speaker (makes it really tough to listen split chasing DX)!


Any ideas what may be causing this?

How do I load an older version back into the K3?
