I contacted Win4K3Suite support and Tom, VA2FSQ says it should work as Jim, N7US and I described, but make sure both radios have the same firmware version.

Hi Folks,

Thanks to all for the response to my question. While I do not intend to upload the configuration of one K3 to another, I do want to have the MENU and CONFIG information pulled from the radio.

It appears that Win4K3suite will do this and I have downloaded the 30 day free trial version to play with and will go from there.

Thanks again for the great information. This is a great list for the best radio I have ever owned.

73,

Bob

Subject: [Elecraft] SDR on K3 IF to look for RFI
Message-ID: <CACYeN9ywrf-gYmiqKPGh0arqQDad9RHX2Q86Nzbp0Hm1JSrOGg@mail.gmail.com>

Now that 160 season is almost over and my antenna farm is doing good I'm
going to start chasing RFI at my new QTH.

I plan to use my RSP2Pro with HDSDR to do some time lapse recording to see
when things come and go as a first step.

To do this I plan to use my existing antennas and I'd like to avoid
connecting and disconnecting my rig as much as possible.

So I'd like to use the IF port of the K3s. That's currently passed to the
P3 and I thought I could use its IF output to drive the SDR.

That would allow me to leave it connected all the time even while using the
K3 for normal use.

How wide is the bandwidth of that port? Is it limited to the 200Khz the P3
presents?

Thanks

Hi Jim,

You want to look at a wider range of frequencies than the K3 IF 
presents.  See:

https://www.nk7z.net/sdr-rfi-survey-p1/

for a how to do this, using an SDRPlay radio.

That link goes to part 1 of a multi-part set of articles covering how I 
use SDRPlay radios to see just what is happening in my RF world.  Part 2 
covers interpreting what you see using a very wide band long term 
recording of your RF environment.  It helps very much in taming RFI to 
look as you are proposing to do.

73s and thanks,

The approach I've used is to use a couple of BNC to BNC jumpers and a 
BNC "T" connector.? Connect the RX OUT to one side of the "T".? Connect 
the RX IN to the other side of the "T" connector. Connect the? RSP2 to 
the other port on the "T" connector.? Then press the RX ANT on the 
radio.? This allows the radio to be active and the RSP2 at the same 
time.? All is protected when/if you transmit.

This gives a very wide bandwidth based on the front end of the K3 and is 
much wider than the K3 IF.

Message-ID: <1554130375243-0.post@n2.nabble.com>

Just had to comment on the iconography of the March 2019 Old Stuff Day.  I'm
old enough to have witnessed all of the icons on that page. Bumper cars?  Of
course.  Manual typewriter (with the beloved Courier font?  Natch.  VW bus? 
Never drove one but saw many on the road.  

All of these are no longer in production---except the K2.  I know, the K2
was not announced in the same year as bumper cars, but to some it is Old
Stuff given the newer digital rigs of the day.  My K2 #6011 is still very
much alive and a joy to operate in CW (my preferred mode) as a QRP rig. 
Today, QRP rigs are available at a lower cost, but, IMHO, the K2 still
offers the most enjoyment/$ for building and operating.  

What a hoot:  the K2 in the same picture as the lava lamp.  The K2 won't
last forever, of course, but the run it has had is a tribute to the vision
and engineering prowess of the Elecraft team.  

Thanks for the memories.

While I agree that the left-right audio balance feature would be nice to see in a basic K3 etc. as update etc. why not just build an outside box to accomplish that. Therefore it could be used on your legacy rigs as well. I could myself use a bit more in the Left side I think.
I already have such a thing as two blending pots in a box that was originally used in my CD Discman to send audio to my regular stereo amp.. two pots for two signals  to balance the sound for the uneven room acoustics (some High End amps - British, you say -  don't have a Balance control and I believe was the intent).

Over the winter I built an external audio CW filter that does WONDERS for older rigs  (not Elecraft... of course) .. makes them a lot better. I just tried it out on a HW-8 this morning and it totally changes the aspects of the rig. Makes my Drake TR-7 usable.. the old Drake CW filters either were not good to be begin with (in comparison to....) or have aged to ringy/hollow sound. Who knows.. but the external CW audio filter (HiPerMite) is a game changer. This makes for a better situation and I did not have to go into the inner guts or workings of any rigs to achieve the 'update'.

So perhaps Wayne and Eric don't have to do all the work... sometimes we can change things for the better by implementing a little of our own soldering and building skills.
Now onto the New England SCAF that is almost finished and ready to test out in a cage match... HI.

Humbly submitted.

Yes, we agree - the delay and averaging for forward power for just the LCD 
display was incorrectly set to too low of a value in 2.10.

Fortunately this is only a LCD display issue and does not impact the Power/SWR 
bargraph or internal operations of the amp.

We'll get this fixed in a new f/w update this week.

Hi Group:
Don't forget, it's not difficult to feed the rig's audio output to a modest audio mixer (check a music store), which would easily permit you to independently adjust the audio levels of the feed to your headset or speakers. ?This could be made to work for a "mono" feed (single receiver) or a "stereo" feed (two receivers).

You could run the K3 audio through your computer system and adjust the 
balance in its sound mixer. Or install more sophisticated mixing 
software like VoiceMeeter which will give you a 15-band graphic 
equalizer and processing effects; also a handy way to record on air 
activity.

Yes, I use a pair of powered computer type speakers.? Feed the two audio 
outputs from the K3 which are on the SPEAKERS/STEREO jack to the L and R 
speaker respectfully.? Adjust the volume on each speaker as you desire.

The ones I use are from the defunct Radio Shack being a Realistic Cat 
40-1313.?? These have the volume control on the front of each speaker.

Wayne and Eric are still running the company, both having taken /T//he 
Elixir/ in 2025.? Elecraft currently generates 12.3 % of the Earth?s 
gross domestic product.

Wayne created the ultimate radio outfit ensemble.? His universal heat 
modulator layer worn next to the skin to wick off excess heat in the 
summer and provide warmth in the winter.? He fiddled with its design 
until it was also an effective Faraday cage.? The outer layer of the 
suit was redesigned to become his antenna. ? Seated or standing it was a 
fine radiator at QRP power levels but absolutely amazing when he cranked 
the power up to 1500 watts.? The aura projected at higher power settings 
was skillfully portrayed by marketing in the virt-ads we see floating 
around us.

While experimenting with shrinking his latest transceivers he 
serendipitously created an amazing power source.? After placing his 
first batch of rigs in the shrink chamber he hit the button. ? 87% of 
the rigs shrank to their intended size but the rest experienced a 
cascade failure and became stable, mini-black holes. ? Luckily his lab 
is in orbit so he vented them into space and sat a while in thought.? 
Eric wandered by and saw his chum?s gloomy visage.? ?What?s up Wayne??, 
he asked.

?I shrank my first set of transceivers today and only 87% of them 
stabilized at their new size. ? The rest became quantum black holes.?

?Did you keep any of them for testing or did you dump them??

?I vented them Eric.?

?Next time keep a few for testing, I have an idea.?

Wayne set up the next batch for miniaturizing and hit the button.? Again 
87% of the rigs turned out fine. ? Perfect 1 centimeter cubes ready to 
be implanted into Elecraft?s customers. ? The remaining 13% disappeared 
as they shrank but he captured them in a containment field so Eric could 
test his hypothesis.

Eric left his virtual meeting with the other world leaders and started 
his experimentation.? He had read Wayne?s reports on the shrink process 
and found an interesting scaling principle.? Once the transceivers 
shrank to less than 1 nanometer their gravitational force grew immensely 
powerful.? When they became quantum black holes they could be used as 
power sources.? He wrote some back of the iPod calculations and left 
them for Wayne?s eager mind.

As they experimented with the ?failed? rigs over the next week the two 
built a harness to contain them and capture their phenomenal power.? 
After a month they had the basis of a working product.? The Eternal 
Power Source ? was ready. ? A steady 1 terawatt output for an estimated 
500 years was eternal enough for the marketing folks.? Elecraft Inc. was 
ready to double the company?s contribution to the Earth?s GDP.? It was 
also ready to transform the transportation industry once Wayne tamed the 
quantum side effects of their creation.? Localized quantum tunneling 
fields described in Eric?s initial notes gave them yet another product 
to market.? Luckily their minions were prepared for the deluge of orders 
over the next six months.

His quest for ever smaller radios had lead Wayne to create another 
spin-off company for Eric to administer.

Great commentary on the venerable K2. I had an experience that some on this
reflector might find interesting. I purchased a Yaesu FT-991A solely for the
purpose of VHF/UHF SSB/CW. (Our local group's been buggin' me to join them
on 2m SSB, hihi.)

Well, I saw C8T on the cluster and decided to give them a call. I wanted to
try the FT-991A on hf, so I unscrewed the PL-259 from the back of the
K2/100, moved it over to the Yaesu, and tuned to 40m. Nothing heard. I made
sure the filter selection was correct, toggled the IPO settings, etc., still
nothing. Switched back to the K2/100 (S/N 3595, fresh from a Don Wilhelm,
W3FPR, thorough upgrade and alignment.) and voil?, there was C8T. Oh it was
weak, to be sure, but readable and subsequently in my log.

I mentioned this to Joel Hallas, W1ZR, during an email discussion re. his
FT-991A QST review and he commented that, while the K2 is a fine radio, he
was surprised. I'm not, the K2's still higher on the Sherwood Receiver Test
List for a reason. (Albeit that ranking's just by close in Dynamic Range,
DR3.) I'll eventually get a CW optimized K3S, however, I'll always love my
K2/100.

"I know, the K2 was not announced in the same year as bumper cars, but to
some it is Old Stuff given the newer digital rigs of the day.  My K2 #6011
is still very much alive and a joy to operate in CW (my preferred mode) as a
QRP rig. 
Today, QRP rigs are available at a lower cost, but, IMHO, the K2 still
offers the most enjoyment/$ for building and operating."

Hi Bill,

We just caught this and it will be corrected in the next 1500 f/w release.

Hi Brad,

I apologize for the confusion on this.

The following K3/K3S menu entry enables the K3/K3S to send out the transmit 
frequency on the AUXBUS cable to the amp and external tuner.

In the K3/K3S KAT3 menu item, tap the 1 key to set it to "KAT500=Y".

It?s documented in the current shipping KPA1500 owners manual, Rev B1 (2/12/19), 
on page 20 at the bottom. (Its also on the website.)

I used a manual typewriter until I got a Selectric that was in use until
1999.  Never had a VW Bus but I had a 1953 VW Bug and later a 1963 Bug
that I did several engine rebuilds and a 12V conversion  but sold it in
1986 before it fell apart.

K2 old?  Mine is the newest rig on the shelf, just beating out my ICOM
IC-2820 VHF/UHF rig.  I don't get to use the K2 much any more after
moving from the house with 13 - count 'em - 13 antennas (2 HF ones) to
an apartment with only a porch-mounted mag-loop for HF - at least I got
to have my VHF/UHF j-poles and ground-planes, only after the very
grunting acceptance of the property owners after I played my "emergency
communication" card.

I am sorry for any confusion. But I used that antenna on the Maldives Isl.
and from D4 (Cape Verde) with great success.

3200 + QSOs as D44TUK on CW and 1400 as D44TUQ (my YL) on RTTY was 
verifying that.

To answer your question now, I have seen that combination with the 4:1 
balun at one of our
competitors in the IARU Fieldday Contest. That was before K3 when the 
Kenwood TS 850S was the
first choice of serious contester.

I love that marvelously performing ANTENNA TUNER in my K3

I am running into the exact same thing. fldigi gets audio and freq from rig
no problem. USB codec selected for fldigi output but rig just shows TX light
but no power out or ALC indication on rig. Nothing plugged into line in
jack. Rig set to TX DATA.  MIC SEL = Line in on rig. Same symptoms with
FreeDV and WSJTx...

USB audio and rig control fine and PPT works but no rig sound card going
out. 

anyone else find this and solved it?

Thanks,

Solved it.

 In TX DATA mode the MIC level controls the LINE IN Level (dah!). So add
that to your checklist!

Mine was at the default 0. Turned it up and level 5 seems to be the right
amount of drive.

Thanks all.

I hope someone has solved this, too, as I am having the identical problem with my KX3. Other digital modes like FT8 work FB. I would like to not have to use VOX to key the rig. I suspect that I just haven't found the right combination of trial & error.

Within FLDIGI there is a transmit audio level control in the lower right 
corner.??? Just below the LK tab.?? I use a value of -15.? The arrows 
left and right of the box will increase or decrease the level going to 
the radio.????? My Line Gain which is adjusted by using the MIC knob is 
at 30.

There are 3 places where the transmit audio level should be adjusted.

(a)?? The computer SPKR level.?? {mine is 30%}

(b)?? The application transmit audio level?? {mine is -15}

(c)?? The radio Line Gain level? {mine is 30}

Ideally, they should never be at a maximum or near minimum value but 
more near "mid range".? I call that between 30 and 50 what ever units 
that may be. ? ? This will prevent overdrive and distortion of a stage 
or circuit.? And these should supply adequate level to the radio to 
produce 4 solid bars showing on the ALC scale.?? With Elecraft radios, 
always set the transmit power output with the PWR control on the radio 
and NEVER with the audio level.??? Also be advised that often when one 
runs another application previously on the computer, the SPKR level many 
change due to the needs or a previously used value.??? Just the way some 
things work.?? Always check the values to prevent frustration, bad 
signals and "nothing works" conditions.

To those having problems with DATA modes, take a look at the article on 
my website www.w3fpr.com.  Scroll the left column to the last article 
and click on it to open the document.

While VOX should reliably put the radio into transmit, you can set 
FLDIGI to use PTT via CAT command - BUT don't use both.

Download and install FLRig. Setup is straight forward and they support K3 (and maybe KX3 but since they're all the same command language, K3 should work). FLRig implements CAT control eliminating the need to use VOX. HTH

Subject: [Elecraft] K3S Problem with Filters
Message-ID: <00ca01d4e958$0d402b10$27c08130$@btinternet.com>

I have recently fitted a Sub Receiver & some additional filters to my new to
me K3S. I now have in the main RX, a 6K for AM, a 2.8K, 2.1K, 0.4K & 0.25K.
In the sub RX there is a 2.8K, 2.1K, 0.7K, 0.4K & 0.25K. I have a problem
with the 0.4K filter position in both receivers. Between about 0.45 & 0.35
in both receivers there is an immediate drop in volume, still copyable but
not working correctly.

Does anyone have any ideas what the problem may be?

Ray,

You can set the gain parameter (FLxGN) parameter in the menu to 
compensate for that.  Either use K3 Utility or set it manually in the 
CONFIG menu.

Message-ID: <CAAL9+5izmaiHSvi25YirkO6cH3PduQmtNDhqr=_YHK2Q7rv=Ng@mail.gmail.com>

I am looking to see if anyone else has used an Ameritron AL811 with their
KX3 with positive results.

I plan on buying the KXPA100, but after buying the Shack in a Bag, I will
need to put it off for a little bit. In the mean time, I would like to try
using what I have, but I am hesitant to try since the KX3 is new to me and
I don't want to harm anything.

I have a base station radio that plugs into the Ameritron AL811 by way of
the ARB-704 and it works great with 70 watts going it to make 600 watts
going out. The ARB amp line is a simple RCA jack from the ARB 704 to the
rear of the Amp, but the radio cord is the Multi cord plugged into my base
station. I know I can unplug the multi cord and use the RCA jack on the
back of the ARB 704 "radio" input, but I am not sure where that will plug
into.

I know that I can only push 15 watts max into the Ameritron, but wouldn't
that mean that I could get somewhere around 180 watts out of it? Would it
work like that?

I bought the cable pack from Elecraft, so I am pretty sure I have
everything that I need to make it happen, but I would love the advice of
someone on here that may have already done this, or has good information on
why I should not try this. I could also use help in which plugs to plug
where.

Thank you for any information that anybody may be able to give and please
forgive me if this has been posted somewhere already. I have done my best
to search for several days online and in this forum, but I am not coming up
with any answers.

I had done that Don as per the Manual - 1-2dB for 400Hz & 3-4 dB for the
250Hz filter. 

To get the right level of loudness I have had to add the max ie.8 dB. So, is
something else wrong?

Dan,

The KX3 has a KEYINE OUT output which will key your amplifier.  It is on 
the ring contact of the ACC 2.5mm jack.  See page 5 of the KX3 manual.

When you add the KXPA100, there is a "black box" on the KX3 to KXPA100 
cable set which brings that KEYLINE signal out to an RCA jack.  See the 
KXPA100 manual.

So if you have only the KX3 now, you will have to build a cable which 
takes the ring contact of a 2.5mm stereo plug out to an RCA plug which 
you would connect to your amplifier.

The KX3 KEYLINE output is rated to accept up to 30 volts and up to 100ma.

Ray,

I doubt that there is anything else wrong.  Each filter will vary in its 
gain (actually loss) amount.  The 4 dB stated in the menu listing for 
the 400 and 250 Hz filters is only a starting point.

My two narrowest filters have CONFIG -> FLx GN set to 6dB as opposed to 
0dB for the others. Press the number keypad to select the appropriate 
filter.

It appears FLDIGI  MAC uses USB for RTTY not the standard LSB. Use data A for RTTY.  If AFSK is used FlDIGI needs to be in REV mode. 
 If FLDIGI is not decoding correctly or no one answers calls, check the mode.
I don?t know if this applies to PC FLDIGI.

FLDIGI working under Windows 10 has no issues using the correct mode for AFSK or PSK. 

In FLDIGI you should be able to select PKTUSB for PSK mode and PKTLSB for AFSK.

I recommend reading the FLDIGI manual.  It states that USB is used for digital modes, including RTTY.  The K3 uses USB for Data A and LSB for Data AFSK. 
In my first contest I was having problems getting reliable decoding and not many responses to my calls. I asked a friend who is an PVRC RTTY expert for help. He monitored my transmission and determined my signal was reversed. He said some operators would see that and change mode to answer me. Enabling Rv (reverse) on the lower FLDIGI control panel solved problem. However my logging software sends a mode command to radio when I select a spot and change frequency and it turns off Rv. A better solution is Data A mode which uses USB. 
There may be a way to change the FLDIGI RTTY  default however I have not found it in the menus. Has anyone found it?

Does using Reverse on the K3 make it easier to use the logging software spots?

According to information available when we added RTTY to the K3, the standard was LSB. So AFSK-A and FSK-D both use LSB. DATA-A and PSK-D both use USB.

This is not left to your imagination during operation, because "LSB" or "USB" is shown along with "DATA" in the mode icon area. (This applies to the K3, K3S, KX3, and KX2.)

You can use DATA-REVERSE to flip the sideband. On an K3, K3S, or KX3, just hold the ALT switch, and you'll see "REV" appear above "DATA." On a KX2 use the ALT MD menu entry.

In FSK-D mode on a K3/K3S you can also reverse the transmit logic polarity; see CONFIG:FSK POL. This would be used with MMTTY (etc.) when driving the FSK hardware input line, as opposed to internal FSK-D operation which uses the keyer paddle or an attached ASCII terminal, e.g. K3 Utility's terminal function.

Tonight, when I turned on my early (sn 431), but upgraded to current, K3, I
was surprised to find I had no speaker audio with either internal or
external speaker(s). My first thought was that I had somehow fried the
speaker AF amp chip. But then I found that the speaker audio worked fine if
the CONFIG were set to SPKR + PH = yes. That would seem to rule out the
speaker amp as the problem. 

Anyone experience this, or have any ideas?

Thanks much!

Joel,

I don?t own a K3 so I am not familiar with all of the audio output settings
but is it possible you have a set of headphones plugged in that is
disconnecting the speaker? If not, maybe a dirty headphone jack?

I was able to turn off logging software mode send so I can use Data A or I could use AFSK with rev. Also it?s possible to change K3 to USB AFSK. it?s not a K3 problem but I thought others might have the issue.  Took me a few hours to sort out It all out.
I might have more info tomorrow.  I need to play with log software rig control config.

I'm a new K3s owner as of October, but I'll take a stab!  I leave phones
plugged in to the back of the rig all of the time and an external speaker
all of the time.  My settings are SPKRS = 2 and SPKR+PH =yes.

Hope that helps!

Tonight, when I turned on my early (sn 431), but upgraded to current, K3, I
was surprised to find I had no speaker audio with either internal or
external speaker(s). My first thought was that I had somehow fried the
speaker AF amp chip. But then I found that the speaker audio worked fine if
the CONFIG were set to SPKR + PH = yes. That would seem to rule out the
speaker amp as the problem. 

Anyone experience this, or have any ideas?

Message-ID: <005801d4e9c4$2137bdb0$63a73910$@optilink.us>

Hey gang.

Just double checking my setup.  I'm using a PK-232sc+ for sound card modes,
FSK RTTY, CW, and PACTOR with my K3s.  I recently added the K144XV and since
everything is already hooked up, I tried sending packet.  After tweaking the
AFSK control on the PK for proper deviation and proper ALC, I gave it a shot
to the local BBS and it works great!  Hit a Winlink gateway or two and used
a digipeater for a few more - worked great.

 

My question, is there a "mode" setting to do what I am doing, or will I need
to change the MIC input to Line-In every time I want to do FM packet instead
of FM voice?  Currently that's the only way to make it work.  On SSB,
changing to data opens the Line-In for data.  Just curious for FM.

 

BTW:  It is interesting to see the open carrier waveform on the P3 of
various 2 meter FM repeaters.  Some look "clean" in my opinion and some look
"dirty" with no voice modulation even though the dead air sounds the same.

 

I enjoy my K3s setup more every time I use it!

Hi Joel,

It sounds like you have phones plugged in somewhere. The traditional way 
of wiring rigs is that plugging in phones mutes the speaker (usually 
they're powered from the same output stage). The K3 has separate output 
stages for spkr and cans, and the switching is done by logic. Most of us 
who plug boom mic headsets into the rear panel assign SPKR + PHONES to 
one of the PF keys -- I use PF2. SPKR+PHONES is a toggle, so it either 
activates or de-activates muting of the speaker.

This is documented in the part of the manual that describes the menu 
system.

Could it be this? I saved this item from a KE7X post. Worked for a 
friend with a similar mystery problem -
VE7XF
.......................................

At one point Elecraft had to change the switch that cuts out speaker 
audio when the phones are plugged in so there is a setting in 
CONFIG:SPRK+PH that selects one of two action polarities.

Tapping the 1 key toggles between PH.R SW- (inverted) and PH.R SW+. Try 
changing that.

Fldigi for the PC operates correctly with the K3 and AFSK_A as long
as radio control (CAT) is connected.  The software/CAT interface
driver properly understands the sideband sense of the connected rig.

Not to worry Richard.? GPS has two PR codes on different frequencies.? 
The "civilian" code repeats every 100 ms. The "military" code repeats 
every 7 days, and the code is sometimes encrypted.? At the end of the 
code, a "week number" is incremented by one and the code repeats.? 
Eventually, the 10-bit register holding the week number will overflow 
and reset to zero. That's all that's happening, it happens every 1,024 
weeks, the first was in Aug 1999.

The first time this happened, the much younger Internet was filled with 
admonitions not to fly between a couple of dates in Aug since airplanes 
would fall from the sky.? It also hatched several conspiracy theories 
[of course].? The hubris surrounding GPS Rollover Day had declined some, 
but as usual, some persists.? It does sound like a good marketing ploy 
however ... "Get your new Trimble now before GPS resets and your old one 
quits."? Kind of what Apple and Microsoft do when I think about it.? [:-)

The GPS reset has been the source of hysteria in various circles, including  
exhaustive discussions on the various private pilot and drone forums, since  
most aircraft and drones use GPS for real time positioning and navigation  
while in flight.

In short, when this happened in 1999, changes were made to lengthen the  
roll over period to beyond our lifetime.  The April 6 rollover only effects  
older GPS devices with the 10-bit registers.  Basically, every GPS embedded  
device made in the last 10-15 years or so will not be affected - only the  
first generation devices.

There are absolutely no warnings or cautions on the websites for Garmin,  
Magellan, or Trimble showing it is a non-issue for their GPS devices - not  
even mentioned.  The FAA has a list of the very few GPS devices used in  
older private aircraft that could be effected, only if in flight when the  
rollover occurs.  With 10,000+ people in the air at any moment, there would  
be a huge air of caution by the FAA and airlines if the rollover had any  
chance of effecting the GPS devices now in use.  In this case, "Silence is  
golden."

The week number register is in the hardware aboard the GPS satellites, 
although receivers usually read and store it too.? Each rollover is a 
"GPS epoch," epoch being a term used by space travelers, astronomers, 
and other folk dabbling in space-ish things to confuse the rest of us.? 
The first epoch ended in Aug 1999 ... 1024 weeks is 19.<mumble> years.? 
We are approaching the end of epoch 2.? In 1999, a few of the early GPS 
receivers hit the WNRO [week number roll over] and thought it had become 
1980 again.? Using a GPS receiver to discipline the K3 involves the 
clock signal and unless you are using your very very old receiver to 
tell you what the current date is, the WNRO will have no effect.

Early in the first GPS epoch, it was discovered that the "civilian" 
signal was yielding somewhat better accuracy than the US Dept. of 
Defense had planned, and they implemented SA or Selective Availability 
to perturb the satellite clocks making it appear that you were moving 
around randomly in a 100-200 m area when you were in fact stationary.? 
This would affect the clock signal at the receivers and thus the 
"discipline" applied to the K3.

It wasn't very long before a number of entities, including manufacturers 
and the US Coast Guard ... found ways to get around SA.? One is 
Differential GPS which places stations at very carefully surveyed 
locations, monitors their GPS reported positions, and transmits the 
errors.? The DGPS receiver uses the errors to correct its own GPS 
position.? If you have the new synthesizer for your K3 [or a K3s], you 
can hear and decode the DGPS signals, they're 100 bps MSK in the 284-458 
KHz range and have a distinctive signature on a P3.? The US DoD gave up 
on SA long ago but the DGPS stations remain, or at least did the last 
time I checked.

One GPS conspiracy theory posited that there was a "back door" into the 
satellites put there by another country [which we'll leave nameless] 
which, when activated, would be used to cause all the aircraft in the 
air to converge on one point and create a great conflagration.? 
Conspiracy theories have a half-life and fortunately this one was fairly 
short, similar to the half-life of disco and leisure suits. [:-)

Not my first rodeo, but I must have fouled something up.  I have the 2.17 folder (containing the .hex and .rtf files) in the local folder for the KPA1500 utility.  The utility says it can talk to the amp.  I tell it to download the files.  I get the usual firmware download window, but it hangs on the ?Verifying file ?kpa1500fw217.hex? message.  The hang has lasted over 20 minutes now before I did a Force Quit.

Suggestions?

Never mind.  While the reboot of macOS did nothing, cycling the amp off then on seems to have gotten by the verification hang.  Firmware installed successfully.

My understanding is that the USCG Beacon system is being shut down. Too bad for us in the Pacific because the beacons provide a good 2 meter accuracy, whereas the WAAS system out here is not as good as on the continent.

I need to make room in the shack?.

K3/100 100 watt 160-6 meter transceiver SN7120, purchased January 2013 for $2249.95, factory-built with following options:
        -KAT-3 Antenna Tuner $339.95
        -KPFLA3A -550 500hZ 5 pole filter $89.95
        -KBF3 General Coverage BPF  $159.95

In January 2017, this K3 was upgraded by Elecraft to have these K3S features:
        -KIOB Upgrade (sound car, audio interface) $389.95
        -KXV3B-F XOUT/XINT transverter interface $199.95
        -KSYN3A UPGD-F synthesizer board upgrade $219.95
        -Neoprene Soft Grip VFO A tuning knob $16.95
        -CABLP3Y Adapter Cable $29.95

At that time, the K3 was factory calibrated and aligned and ?meets or exceeds all factory specifications.?

Elecraft P3 Panadapter SN820 purchased used for $650.
        -P3SVGA Video Adapter $289.95 installed by me

Both units are cosmetically perfect, from non-smoking environment, always in shack. I am original owner of K3. I have manuals, Elecraft invoices, custom covers for both, the handheld microphone, and the original box for the K3.

I would like to sell the entire package. $2900, includes shipping in US

It appears FLDIGI  MAC uses USB for RTTY not the standard LSB. Use data A for RTTY.  If AFSK is used FlDIGI needs to be in REV mode.
 If FLDIGI is not decoding correctly or no one answers calls, check the mode.
I don?t know if this applies to PC FLDIGI.

FLDIGI working under Windows 10 has no issues using the correct mode for AFSK or PSK.

In FLDIGI you should be able to select PKTUSB for PSK mode and PKTLSB for AFSK.

I recommend reading the FLDIGI manual.  It states that USB is used for digital modes, including RTTY.  The K3 uses USB for Data A and LSB for Data AFSK.
In my first contest I was having problems getting reliable decoding and not many responses to my calls. I asked a friend who is an PVRC RTTY expert for help. He monitored my transmission and determined my signal was reversed. He said some operators would see that and change mode to answer me. Enabling Rv (reverse) on the lower FLDIGI control panel solved problem. However my logging software sends a mode command to radio when I select a spot and change frequency and it turns off Rv. A better solution is Data A mode which uses USB.
There may be a way to change the FLDIGI RTTY  default however I have not found it in the menus. Has anyone found it?

Does using Reverse on the K3 make it easier to use the logging software spots?

According to information available when we added RTTY to the K3, the standard was LSB. So AFSK-A and FSK-D both use LSB. DATA-A and PSK-D both use USB.

This is not left to your imagination during operation, because "LSB" or "USB" is shown along with "DATA" in the mode icon area. (This applies to the K3, K3S, KX3, and KX2.)

You can use DATA-REVERSE to flip the sideband. On an K3, K3S, or KX3, just hold the ALT switch, and you'll see "REV" appear above "DATA." On a KX2 use the ALT MD menu entry.

In FSK-D mode on a K3/K3S you can also reverse the transmit logic polarity; see CONFIG:FSK POL. This would be used with MMTTY (etc.) when driving the FSK hardware input line, as opposed to internal FSK-D operation which uses the keyer paddle or an attached ASCII terminal, e.g. K3 Utility's terminal function.

Tonight, when I turned on my early (sn 431), but upgraded to current, K3, I
was surprised to find I had no speaker audio with either internal or
external speaker(s). My first thought was that I had somehow fried the
speaker AF amp chip. But then I found that the speaker audio worked fine if
the CONFIG were set to SPKR + PH = yes. That would seem to rule out the
speaker amp as the problem.

Anyone experience this, or have any ideas?

Thanks much!

Joel,

I don?t own a K3 so I am not familiar with all of the audio output settings
but is it possible you have a set of headphones plugged in that is
disconnecting the speaker? If not, maybe a dirty headphone jack?

I was able to turn off logging software mode send so I can use Data A or I could use AFSK with rev. Also it?s possible to change K3 to USB AFSK. it?s not a K3 problem but I thought others might have the issue.  Took me a few hours to sort out It all out.
I might have more info tomorrow.  I need to play with log software rig control config.

I'm a new K3s owner as of October, but I'll take a stab!  I leave phones
plugged in to the back of the rig all of the time and an external speaker
all of the time.  My settings are SPKRS = 2 and SPKR+PH =yes.

Hope that helps!

Hey gang.

Just double checking my setup.  I'm using a PK-232sc+ for sound card modes,
FSK RTTY, CW, and PACTOR with my K3s.  I recently added the K144XV and since
everything is already hooked up, I tried sending packet.  After tweaking the
AFSK control on the PK for proper deviation and proper ALC, I gave it a shot
to the local BBS and it works great!  Hit a Winlink gateway or two and used
a digipeater for a few more - worked great.



My question, is there a "mode" setting to do what I am doing, or will I need
to change the MIC input to Line-In every time I want to do FM packet instead
of FM voice?  Currently that's the only way to make it work.  On SSB,
changing to data opens the Line-In for data.  Just curious for FM.



BTW:  It is interesting to see the open carrier waveform on the P3 of
various 2 meter FM repeaters.  Some look "clean" in my opinion and some look
"dirty" with no voice modulation even though the dead air sounds the same.



I enjoy my K3s setup more every time I use it!

Hi Joel,

It sounds like you have phones plugged in somewhere. The traditional way
of wiring rigs is that plugging in phones mutes the speaker (usually
they're powered from the same output stage). The K3 has separate output
stages for spkr and cans, and the switching is done by logic. Most of us
who plug boom mic headsets into the rear panel assign SPKR + PHONES to
one of the PF keys -- I use PF2. SPKR+PHONES is a toggle, so it either
activates or de-activates muting of the speaker.

This is documented in the part of the manual that describes the menu
system.

Could it be this? I saved this item from a KE7X post. Worked for a
friend with a similar mystery problem -
VE7XF
.......................................

At one point Elecraft had to change the switch that cuts out speaker
audio when the phones are plugged in so there is a setting in
CONFIG:SPRK+PH that selects one of two action polarities.

Tapping the 1 key toggles between PH.R SW- (inverted) and PH.R SW+. Try
changing that.

Fldigi for the PC operates correctly with the K3 and AFSK_A as long
as radio control (CAT) is connected.  The software/CAT interface
driver properly understands the sideband sense of the connected rig.

On April 6th the satellite GPS system is going to be reset, does  anyone out there know how this ?reset? will effect the Trimble Thunderbolt that many of us use to ?discipline ? the frequency on our K3 and K3S radios? I?m told that older sat programs will not work after the reset. My Trimble unit was old (surplus) when I purchased it on Ebay years ago. Thanks.

Not to worry Richard.? GPS has two PR codes on different frequencies.?
The "civilian" code repeats every 100 ms. The "military" code repeats
every 7 days, and the code is sometimes encrypted.? At the end of the
code, a "week number" is incremented by one and the code repeats.?
Eventually, the 10-bit register holding the week number will overflow
and reset to zero. That's all that's happening, it happens every 1,024
weeks, the first was in Aug 1999.

The first time this happened, the much younger Internet was filled with
admonitions not to fly between a couple of dates in Aug since airplanes
would fall from the sky.? It also hatched several conspiracy theories
[of course].? The hubris surrounding GPS Rollover Day had declined some,
but as usual, some persists.? It does sound like a good marketing ploy
however ... "Get your new Trimble now before GPS resets and your old one
quits."? Kind of what Apple and Microsoft do when I think about it.? [:-)

The GPS reset has been the source of hysteria in various circles, including
exhaustive discussions on the various private pilot and drone forums, since
most aircraft and drones use GPS for real time positioning and navigation
while in flight.

In short, when this happened in 1999, changes were made to lengthen the
roll over period to beyond our lifetime.  The April 6 rollover only effects
older GPS devices with the 10-bit registers.  Basically, every GPS embedded
device made in the last 10-15 years or so will not be affected - only the
first generation devices.

There are absolutely no warnings or cautions on the websites for Garmin,
Magellan, or Trimble showing it is a non-issue for their GPS devices - not
even mentioned.  The FAA has a list of the very few GPS devices used in
older private aircraft that could be effected, only if in flight when the
rollover occurs.  With 10,000+ people in the air at any moment, there would
be a huge air of caution by the FAA and airlines if the rollover had any
chance of effecting the GPS devices now in use.  In this case, "Silence is
golden."

The week number register is in the hardware aboard the GPS satellites,
although receivers usually read and store it too.? Each rollover is a
"GPS epoch," epoch being a term used by space travelers, astronomers,
and other folk dabbling in space-ish things to confuse the rest of us.?
The first epoch ended in Aug 1999 ... 1024 weeks is 19.<mumble> years.?
We are approaching the end of epoch 2.? In 1999, a few of the early GPS
receivers hit the WNRO [week number roll over] and thought it had become
1980 again.? Using a GPS receiver to discipline the K3 involves the
clock signal and unless you are using your very very old receiver to
tell you what the current date is, the WNRO will have no effect.

Early in the first GPS epoch, it was discovered that the "civilian"
signal was yielding somewhat better accuracy than the US Dept. of
Defense had planned, and they implemented SA or Selective Availability
to perturb the satellite clocks making it appear that you were moving
around randomly in a 100-200 m area when you were in fact stationary.?
This would affect the clock signal at the receivers and thus the
"discipline" applied to the K3.

It wasn't very long before a number of entities, including manufacturers
and the US Coast Guard ... found ways to get around SA.? One is
Differential GPS which places stations at very carefully surveyed
locations, monitors their GPS reported positions, and transmits the
errors.? The DGPS receiver uses the errors to correct its own GPS
position.? If you have the new synthesizer for your K3 [or a K3s], you
can hear and decode the DGPS signals, they're 100 bps MSK in the 284-458
KHz range and have a distinctive signature on a P3.? The US DoD gave up
on SA long ago but the DGPS stations remain, or at least did the last
time I checked.

One GPS conspiracy theory posited that there was a "back door" into the
satellites put there by another country [which we'll leave nameless]
which, when activated, would be used to cause all the aircraft in the
air to converge on one point and create a great conflagration.?
Conspiracy theories have a half-life and fortunately this one was fairly
short, similar to the half-life of disco and leisure suits. [:-)

If you go into the K3S CONFIG menu to LIN OUT the normal value is 10.?? 
I suggest you back this down to 5.? This will then allow the Windows 7 
Pro sound card slider to operate near mid range thus? 0 dB or 50% 
depending on how it is displayed.

The P26 cable works fine to connect a P3 with a K3.  The S14 "Y" is comprised of two female connectors and one male and can be used to connect the P3 to the K3 but not the SteppIR SDA2000 antenna controller.  Given the requirement for these three devices be interconnected is there anyone out there who has surmounted this problem?

Just to check, I suggest going to WWV at 10 MHZ and in CW mode and press 
SPOT.? That will automatically lock to the WWV carrier and your selected 
sidetone frequency.?? No audio or zero beating needed. ?? If indeed your 
radio is off 800 Hz then the SPOT function will not bring it in and 
lock.?? If it is 100 Hz or less usually SPOT will bring it in.?? When it 
locks it will show the frequency and you can then know exactly what the 
error is referenced to WWV.??? Should be able to have an accuracy of +/- 
1 Hz using this method.?? If it is greater than this, I suggest tweaking 
your REF CAL value a few Hz up or down as needed.

There is a warning on the TomTom site - and today I received an email from
them regarding an older Garmin Etrex unit I own. It said in brief:
=======================
Due to the upcoming WNRO on 6 April 2019, the performance of your device 
will be impacted.

While we no longer offer content and service updates for your device, we 
have made an update available that addresses the GPS Week Number Rollover 
(WNRO).

TO UPDATE: Connect your device to your computer. Click the 'update now' 
button for instructions? on how to update your device.
=======================
The message included the serial number of my device, so I suppose I must 
have registered it after purchasing it. The warning page is here:

Check "SW TONE" in the Config menu. I think that is what you are looking
for.

Subject: [Elecraft] KNB1 Installation Order & Diode
Message-ID: <1554401934969-0.post@n2.nabble.com>

I've completed my K1 RF Board, 4 Band Filter Board, and Antenna Tuner Board,
and I am now moving on to Transmitter alignment before installing the
Antenna Tuner.  

I discovered the KNB1 Noise Blanker is still available and just received it. 
(Thanks, Elecraft!)    

1)  I'm assuming I should install the Antenna Tuner first, then install the
KNB1 - is that correct?

2)  As to replacing D2 (1N4148) WITH D2A (green LED) - what are the
arguments for and against that?  As I will be using the K1 in a variety of
locations in the Field it will obviously be impractical to install the diode
on site if I discover high noise level interference there.  Why not just
initially install the diode to raise the threshold in order to cover worst
case scenarios?

Hi John,

The Configuration menu you want is SW TONE.  Set it OFF.

Cheers,

Subject: [Elecraft] April 6th GPS Reset
Message-ID: <mailman.195.1554407137.2815.elecraft@mailman.qth.net>

As NW8L pointed out, there are simple updates to restore proper date displays in GPS receivers.

An update should have a release date inside the build with the associated GPS week number when it was released.  With a little coding, this will allow the receiver to display date properly for 1024 weeks following the release date.

Another design peril is the Age of Data counters for almanac and ephemeris data which are 9 bits.  A company from Illinois thought they could get by with an 8-bit byte, but in July 2004, a whole bunch of their mobile phones went screen of death at the transition from week 255 to week 256.

Somebody commented that WAAS in HI was not as good in the ConUS.  I wonder where this came from.  I cannot imagine the FAA would put up with this unless it is just too easy to land a plane in HI.  In 2017 the GPS guys at Los Angeles AFB were indicating 40 cm repeatability, around 1.3 nanoseconds without WAAS.

Stephen,

The pinout for the MD2 microphone is the same as the MH2 and MH4.
Bias requirement is also the same - it needs a 5.6k resistor from the AF 
signal (pin 1) and either +5 or +8 volts.
The pinout matches the mic jack wiring which is shown in the K3/K3S 
manual on page 13.

Download the K3 manual if you don't have it.

You may also find the microphone pinout at the G4WPW website which has 
been preserved at https://www.qsl.net/g4wpw/date.html#others.

Hint: connect both pin 7 and pin 8 to the common ground.

73,
Don W3FPR

Two suggestions which can probably be added in firmware for K3 and K3s:

1)? Allow different audio levels for speaker and phones, such as an 
attenuation applicable to either.

2)? Allow (but not require) the monitor level to be controlled along 
with the receiver levels.

If either is already available for the K3, someone please let me know!

The K1 options can be installed in any order.

As far as the D2 diode, that is entirely your choice, and should be 
based on your local noise situation.

I have also thought that an audible SWR indicator would be very useful 
but never bothered to mention it as most would probably consider it to 
be a little too gimmicky. But it would be quite handy for me when I'm 
using an external match box-- when I lean across the desk to adjust it I 
can no longer easily see the little SWR meter indicator in the K3 display.

I'd suggest a "geiger counter" type audible indicator: a fast beep  for 
SWR values greter than 3:1 and progressively slower as you zero in on 1:1.

I don't expect to see it for the K3 but perhaps someday a K4 will have a 
CW pitch adjustment that:

a) does not blank the received signals when you engage it as the current 
sidetone pitch adjustment does;

b) keeps the signal centered in the passband while pitch is adjusted, 
unlike when you adjust RIT or VFO to change a signal's pitch.

I suppose that would be useful, as long as it didn?t beep at you incessantly every time an internal ATU cycle was run.

But If I had to reach around to use an external matchbox and didn?t have a visual indication of SWR while trying to do that, I think I?d rearrange my station :-)  Trying to tune a matchbox with nothing but a digital readout (rather than an analog meter indication) is a hair-pulling PITA anyway.

I suggest the audible SWR indicator be in effect only while the TUNE 
button is being pressed. But I'm not sure if such an indicator is even 
feasible as I understand there is some "mission critical" code in the K3 
that senses catastrophic antenna failure. An audible SWR indicator might 
perhaps steal some cycles from that code, I don't know. But again I 
suggest it only while TUNE is engaged so perhaps we could risk not 
having protection against an antenna failure during these brief tuning 
periods and touching up the SWR.

As to my station arrangement, it is precisely the reason why I use a 
manual t-match on the other end of the desk: to keep my endfed wire and 
its counterpoises, which would otherwise connect directly to the K3, 
nearer to their egress point from the shack. So, the arrangement is by 
intention.

Sorry John, I misread your post.  To have the sw tones, SW TONE should be ON.  If it is, I don't know why you don't get tones except some switches like REV and M1 - M4 don't generate tones.

SW Tone is on, but there is no beep when the button is pushed. Any other suggestions on how to turn on the button beep?

Hi John,

The Configuration menu you want is SW TONE.  Set it OFF.

I have two K3s. The first one emits a beep in the speaker or headphone
whenever a button is pushed. The second one doesn't. I can't find
anyplace to turn the function on. Is there a button or menu setting that
I'm missing?

Subject: [Elecraft] New release of Win4K3Suite, Version 2.002
Message-ID: <006001d4ebe4$355ac900$a0105b00$@videotron.ca>

Hello,
There is a new version of Win4K3Suite available, version 2.002.  For those
of you who know the software, going to version 2 doesn't necessarily mean
major changes since the software has been around for 6+ years and has had
dozens of enhancements. This version though is worthy of the version 2
designation. 
Win4K3Suite now has user customizable Skins, that can change the look and
feel of Win4K3.  Be sure to check out the pre-defined skins or create your
own.  Here is an example:
https://va2fsq.com/wp-content/uploads/Win4K3-Version-2.png

This version also now requires .NET 4.6 or higher.  This will be
automatically installed by Windows if it does not exist.  If you computer
asks to be rebooted, accept and then when it restarted, run the installation
of Win4K3 again.  That will bring it up to date.  Be sure to follow the
detailed instructions on the download page.
Win4K3Suite is a full featured control program for the K3/S, KX3 and KX2.
It has a built in Panadapter that works with LPPAN and a sound card, as well
as the SDRPlay RSP's. It supports the KAT500, KPA500/1500 and the KXPA100 on
most of the above radios.  A unique feature is that is has 6 built in
Virtual Radios, each of which works just like an Elecraft radio.  This
allows sharing of a single COM port with up to 6 applications.  It also has
a built in HRDLogbook server and the EiBi Shortwave database which is now up
to date.

Use PKTUSB with fldigi digital modes.  This is covered in the fldigi docs.

That option is not available or I would. The drop down box is blank. The instructions I read say use RTTY and have the radio in LSB.

Ray and all,

The K3/K3S/KX3/KX2 has a DATA submode AFSK A which is LSB (unless you 
change it) and also has special filters for RTTY - you have to set the 
mark frequency in the menu to match your software (or the other way 
around).
Using the DATA submodes rather than SSB automatically sets the 
compression to zero and the TX and RX EQ to flat.  That allows you to 
switch to DATA modes without disturbing whatever compression and EQ 
settings you have set for SSB.

Read the Elecraft manuals for more information.

So if you set the K3 to AFSK A, you are placing the K3 in USB mode and 
complying with the FLDIGI instructions that you read.

FLDIGI instructions do not consider the features available on the K3 
because they are written for the lowest common denominator and apply to 
transceivers that do not have specific DATA modes.

As a side note, for non-RTTY soundcard data modes, use K3 DATA submode 
DATA A rather than SSB USB.

Don W3FPR

When FLDIGI rig control is ?XML-RPC? the mode select drop down box under frequency is disabled. In that rig control mode Data A which is USB needs to be use.  I did not realize until I just checked FLDIGI that it is only disabled in that rig control mode.

Great Ideas!  May I suggest, in the name of ?feature creep?, a suggestion?  So, have the K3 or K3s dial up your cell phone where you can program specialty ring tones for all sorts of ?mission critical? events.  This will surely get our attention while in the heat of battle for another 59 contact.  Or not!

Message-ID: <BYAPR16MB296869A91CC316834299E6B28C520@BYAPR16MB2968.namprd16.prod.outlook.com>

An unexpected shut down of my station PC led to a cascading failure that caused my Arduino station logger to key my KPA500.    I was alerted to the problem by the KPA500 fan running a level 1.  Indicated temperature was 50 deg C.   I estimate that my KPA500 was continuously keyed with no RF drive for about 2 hours.

My system design error was corrected by adding a blocking diode between my Arduino station logger and the KAT500 key line so it won't happen again. (Arduino monitors the state of the key line but pulled it low when it lost power from the USB hub).

My question - Is there any possibility that my KPA500 suffered any harm from being keyed for such a long time with no drive?

Message-ID: <6E2E704B31074E60912BDB65D67BB0F6@LAPTOPEPVQLR1I>

Hi All,

I read the Captain's letter with great interest.  It certainly appears the 
group was subjected to some extremely severe conditions. I get the 
impression the Captain is almost apologizing, and I have to wonder why, 
unless they were possibly a bit too aggressive about certain things.

In any event, this seems to have been "the DXpedition from hell"!  Lots of 
problems, several delays, and an enormous amount of energy being expended 
just to operate from an island that apparently isn't fit for inhabitation! 
Apparently the stars have to line up just right for them to even go 
ashore!!!  I really enjoy chasing DX, and working a lot of these DXpeditions 
to exotic places, but some places seem to be TOO exotic (as in dangerous!) 
in my view!  I still shake my head a bit when I look at pictures from that 
last Kingman Reef DXpedition, where they operated from a pile of rocks!!

I've been amazed at how involved this operation has been.  As an example, 
take a look below at a posting the group made back in January:

"Update Jan,2: WE?RE AWARE WE START TO FACE A SITUATION THE MOST SUITABLE 
AND SAFE WEATHER PERMITTING SEASON TO REACH BOUVET ISLAND IS ABOUT TO SLIP 
AWAY. NEVERTHELESS, WE?RE IN SOUTH AFRICA SINCE THE LAST DAYS OF OCTOBER, 
TRYING SO HARD, SACRIFICING OUR FAMILY TIME, JOBS, MONEY AND OTHER RESOURCES 
TO MAKE IT ALL HAPPEN FOR YOU, DXERS."

Apparently some, or all, of them have been down in South Africa for nearly 6 
months!!  That's incredible!  All that "sacrificing" they refer to above 
seems like a hell of a lot to pay for us to get some contacts with Bouvet. 
Is is really worth it??  They are actually putting themselves at great risk, 
and I have to question the justification for doing so.  They have even had 
to take "cold water rescue training", which sounds terribly dangerous.

I'm no meteorologist, but I'm assuming the time has passed for any further 
attempt this year.  It's spring here, so it's fall there, and the WX can 
only get worse I assume.  They have said it is postponed, and not cancelled, 
but they haven't indicated if that means postponed until next season.  I

In one off-line reply I was asked why the temperature rose to 50 deg C.

With a room temperature of about 25 deg C  the temperature of my KPA500 PA module when not keyed runs about 34 deg C.  Measured PA dissipation when keyed with no drive is 40.75 W.    It seems reasonable that 40.75 W could raise the PA module temperature from 34 deg C to the fan 1 trip temperature of 50 deg C.

The irony is that my Arduino data logger records KPA500 temperature at 3 different locations.  Had it been running I would have recorded some interesting data.   However, it was the fact that it lost power that caused the event.   Now, of course, I'm tempted to repeat the event with the logger running.

Subject: [Elecraft] KAT500 SWR LED Doesn't Light with 1.0/1 SWR
Message-ID: <1554573693590-0.post@n2.nabble.com>

I recently added the KAT500 and KPA500 to my K3 station. 

I have noticed that when the SWR (after tuning)  as displayed on the KPA500
is 1.0/1  (or occasionally 1.1/1) no SWR LED lights up on the KAT500. (The
green 1.0/1 SWR LED on the KPA500 does light up.)

I have assumed that the 1.2/1 KAT500 SWR LED does not light up is because 1)
the KAT500  threshold for the first SWR LED is 1.2/1 and 2) because no
tuning action has taken place in these circumstances (due to memorized
KAT500 tuning configuration).  However, I noticed at the bottom of page 49
of Fred Cady's book on the KAT500 and the KPA500 it says "VSWR is displayed
even when the tuner is bypasssed". So, I'm confused. Does no SWR LED light
when the SWR is 1.0/1 (or very close to it) because the SWR is below 1.2/1?

Thanks,

Brian, K8GRR

We lived in Auburn CA for 38 years and the transcontinental Union 
Pacific goes right through town [we lived about 1/4 mile from both 
tracks].? The eastbound track crosses I-80 at the south end of town on a 
very high trestle.? Just after Elecraft had coined the term "K-Line," I 
saw a container train on the trestle with a bunch of "K-Line" 
containers.? First thought was that Elecraft sales had exploded in 
volume to fill that many shipping containers.? I emailed Eric and asked 
if their product name might be a trademark infringement on the Japanese 
company. He explained that trademarks are registered by business sector 
and the Elecraft K-line was safe since Elecraft wasn't a shipping 
company and Kawasaki Kisen Kaisha didn't make ham radios.

Those same tracks run through Sparks NV where we now live.? Nevada has 
no inventory tax on wholesale goods, so we have a huge number of 
distribution centers [like Amazon], and I see those K-Line container 
trains and trucks with triple trailers all the time and occasionally 
imagine them filled with "real" K-lines.

Yes I have that combination, KPA500 / KAT500.  Over the years I've learned that a VSWR of 1.5:1 or less means little to nothing.   Oh it's "comforting" to operate all the time with a 1.1:1 SWR but just accurate is that indication?  And the fact the two devices show different values lends credence to " just how accurate is that indication".  Plus many diode detection methods are least accurate at lower levels. 

Conclusion: find something more interesting to worry about.

Does the power output LEDs give a reading?  If they do and you show no reflected that should be ok.  If you have a bride after that it may show no lite either.  You can always bypass the KPA's and find a frequency where you see 2:1 then turn the KPA's back on and see if that gives a reading.  If not, suggest you call tech support.

The SWR LED scaling on the KPA500 is different than the scaling on the KAT500.  Yet the KPA500 does have a numerical readout......if one wishes to split hairs. 1.0, 1.1, 1.2, 1.3 and etc. 

With LED type displays, there is always a "transition" point from one value / LED to the next.  It could be at 1.4, or 1.5 or 1.6. Thus a value of 1.4 on one device could be 1.6 on another.

Bob, thanks for input, but I understand the issue as to not get a reading on the SWR display of the KTA500 and the concern is there may be something amiss.  Thus my suggestion to be sure the SWR LED is working and to figure it out, I suggested a simple method to make sure the LED on the SWR indicator can register/is working.

Brian:

Your KAT500 low order SWR LED, labeled "1.2", is illuminated when there is a
little bit of forward power and an SWR of 1.2:1  or higher is computed.  If
the SWR is under 1.2:1, then no KAT500 SWR LEDs are illuminated. Even 500
watts of RF with little or no reflected power shouldn't light any KAT500 SWR
LEDs.  The KPA500 (and KPA1500) have an SWR bar LED for 1.0.  The KAT500's
first SWR LED is 1.2.

Fred's book is correct; your KAT500 performs an SWR calculation whether or
not the ATU is bypassed. That result can be displayed with the KAT500
Utility Operate page, or any other program that can send a command to the
KAT500 to read its SWR. If SWR is 1.2:1 or higher, then it's also displayed
on KAT500 SWR LEDs.

I recently added the KAT500 and KPA500 to my K3 station. 

I have noticed that when the SWR (after tuning)  as displayed on the KPA500
is 1.0/1  (or occasionally 1.1/1) no SWR LED lights up on the KAT500. (The

I have assumed that the 1.2/1 KAT500 SWR LED does not light up is because 1)
the KAT500  threshold for the first SWR LED is 1.2/1 and 2) because no
tuning action has taken place in these circumstances (due to memorized
KAT500 tuning configuration).  However, I noticed at the bottom of page 49
of Fred Cady's book on the KAT500 and the KPA500 it says "VSWR is displayed
even when the tuner is bypasssed". So, I'm confused. Does no SWR LED light
when the SWR is 1.0/1 (or very close to it) because the SWR is below 1.2/1?

Thanks,

Subject: Re: [Elecraft] KAT500 SWR LED Doesn't Light with 1.0/1 SWR

Brian:

Your KAT500 low order SWR LED, labeled "1.2", is illuminated when there is a little bit of forward power and an SWR of 1.2:1  or higher is computed.  If the SWR is under 1.2:1, then no KAT500 SWR LEDs are illuminated. Even 500 watts of RF with little or no reflected power shouldn't light any KAT500 SWR LEDs.  The KPA500 (and KPA1500) have an SWR bar LED for 1.0.  The KAT500's first SWR LED is 1.2.

Fred's book is correct; your KAT500 performs an SWR calculation whether or not the ATU is bypassed. That result can be displayed with the KAT500 Utility Operate page, or any other program that can send a command to the
KAT500 to read its SWR. If SWR is 1.2:1 or higher, then it's also displayed on KAT500 SWR LEDs.

Subject: [Elecraft] KAT500 SWR LED Doesn't Light with 1.0/1 SWR

I recently added the KAT500 and KPA500 to my K3 station. 

I have noticed that when the SWR (after tuning)  as displayed on the KPA500 is 1.0/1  (or occasionally 1.1/1) no SWR LED lights up on the KAT500. (The green 1.0/1 SWR LED on the KPA500 does light up.)

I have assumed that the 1.2/1 KAT500 SWR LED does not light up is because 1) the KAT500  threshold for the first SWR LED is 1.2/1 and 2) because no tuning action has taken place in these circumstances (due to memorized
KAT500 tuning configuration).  However, I noticed at the bottom of page 49 of Fred Cady's book on the KAT500 and the KPA500 it says "VSWR is displayed even when the tuner is bypasssed". So, I'm confused. Does no SWR LED light when the SWR is 1.0/1 (or very close to it) because the SWR is below 1.2/1?

Thanks,

Brian, K8GRR

That's normal.  Why would you expect a 1.2 SWR LED to be lit when the SWR value is less than 1.2? 

The range of the KPA500 LED SWR display is much greater that the range of the KAT500 LED SWR display.   Also, neither of them will give a useful reading at low power levels.  I suggest the LP-100A if you really want to know the load presented by  your antenna system.  It will give useful complex load information with power levels between 1 watt and legal limit.

The fact that the two LED SWR meters have different ranges, and different step points, may be by design.  If the LED meters were identical people would perhaps expect them to always display the same value.

Don't forget that SWR is a poor indicator of antenna system load and the KPA500 really dislikes low R loads even if the SWR is less than 1.5:1.

All,

To amplify Bob's comments ---

That is one of the situations with digital displays Vs. analog.
An analog display might show your an SWR of 1.55 (if you can interpolate 
the needle position) while the digital display resolution will show you 
either a 1.5 or a 1.6 indication - there is no way to show an in-between 
reading on a digital display.

Don W3FPR

Does your K2 need repair? Tuneup?
Want to sell it, but it needs some attention before offering it for sale? 

In addition to tuning your rig, I can also rescue a building project you might have started some time ago.

MFJ has been a leader in automatic tuner technology for years. It was 
probably a very simple engineering process for them to use what they 
have to create a K3 tuner. You may have a dislike of MFJ products. But, 
that doesn't preclude the fact that their tuners work very well. They 
have been selling the K3 tuner for years. It doesn't seem the least bit 
surprising given the modular nature of the K3 and the long history MFJ 
has with automatic tuner technology. Maybe it's actually a complement to 
Elecraft that MFJ takes the K3 so seriously.

In-Reply-To: <1289258154200-5719064.post@n2.nabble.com>

Message-ID: <1554652870150-0.post@n2.nabble.com>

This is an old thread, but is something that I have struggled with on my own
K2.  I also had some RF feedback that was mixed with this, but I have cured
that.

So now I am left with the very similar symptoms where there are too many ALC
lights lit for 40m and it overdrives my KPA500.  I had to play with SSBA,
which I would set to 1 on 40m and 2 on 20m.  But even with SSBA set to 1 I
get much to much power on 40m for the amplifier.  I am using the MH2 mic.

I went through the checks.  I have the new PA.  There are only 1-2 ALC bars
lit on 20m and 15m.  There are typically 7 lit on 40m.

With SSBA set to 1 the voltage at KSB2 U1 pin 10 was not near zero.  It was
2.5V.  I checked the values and soldering of R14 and R15 and all looked ok. 
As were the other components listed.

Thinking that the incorrect voltage means that I should change the component
values I updated R9 to 15k and added a 1k between the base of Q1 and P1 pin
6.  The voltage is now near zero, but it has not improved things.

I still need to use SSBA 2 for 20m otherwise the drive is low.  But SSBA 1
on 40m has too much drive.  As soon as the KPA100 clicks in (as I turn from
10-11Watts) the amp is over driven.

Any suggestions?

Wonder if it's held in the K3 with hot glue like they use to hold the panel
meters in their antenna tuners .... have seen this in a tuner purchased by
a friend.

There isn't really much in the way of smarts on the clone board.  It's simply the tuner elements (coils and capacitors), a few relays, the relay driver chips, and gas tubes.  The actual tuning smarts comes from elsewhere within the K3.  This isn?t much of a stretch for a clone.

MFJ has been a leader in automatic tuner technology for years. It was probably a very simple engineering process for them to use what they have to create a K3 tuner. You may have a dislike of MFJ products. But, that doesn't preclude the fact that their tuners work very well. They have been selling the K3 tuner for years. It doesn't seem the least bit surprising given the modular nature of the K3 and the long history MFJ has with automatic tuner technology. Maybe it's actually a complement to Elecraft that MFJ takes the K3 so seriously.

I need an automatic tuner antenna for an ACOM A1000 amplifier. Does anyone
know of any brand or dealer that sells this antenna tuner? Will MFJ release
an automatic tuner antenna for 1000 watts? I hope some guidance response.
Thank you.

I've used many MFJ products and in have had very little trouble with any of them. For example, I make frequent use an MFJ-223 hand-held VNA -- it's versatile and does the job. I've also used their manual tuners, antenna switches, and portable/mobile whips. They have a very comprehensive product line that's really unique in the industry.

That said, I do have some suggestions for MFJ's engineering team on how they might improve their ATU. 

Looking at the photo, I see that they used much smaller toroidal cores for 5 of the 8 inductors in the L network. This could result in excessive heating, especially on the higher bands, at full power into a worst-case match. We specified T68 sized cores to remain conservative based on extensive testing. Also, if you click on the photo to see the details, you'll see what appears to be very inconsistent hand soldering of the SMD components. While this doesn't necessarily worsen performance or reliability, it should be done in a way that inspires confidence in the buyer. (Easy for me to say, of course. We have the luxury of mass-producing these assemblies using automated pick-and-place equipment at our fabricator in Monterey.)

That's correct. The heart of any binary-weighted L-network ATU is in the firmware, which we've been improving since I first wrote the code for the KAT2. The latest incarnation of this code is in the KAT1500, the ATU included in the KPA1500 amp. My colleague K6KR has done a great job of tweaking the algorithm to eek out that last tenth of an SWR unit on every match.

Perhaps the matter stems from the nationality of MFJ's owner and a
different set of values.

The K3 has been out of production for four years, why is the top of  
the line Elecraft transceiver still commonly refereed to as a K3 and  
not a K3S?

John KK9A - PJ4R in last weekend's WPX where I used my K3S.

Indeed, he is 100% American.  Watch the YouTube video where he gives a 
tour of the factory if you have any doubt!  He talks about his ancestors 
coming over to work on the railroads...and has a wonderful Southern accent.

Hi Paul,

I'm sorry. I haven't received any emails except this one. The LP-PAN is 
available. I'll hold it for you until you can make a decision.

Please let me know what you posted in the other emails so I can answer 
any questions.

Use this gmail address until I can figure out what happened with

Hi everyone,
I had to jump in.  I?ve known Martin for over 40 years and he is a fine Southern gentleman who received his M.S.E.E. from Mississippi State University.  I too have an Asian heritage as my mother was Japanese.  I bet you can?t guess what roots my father had.  We love our USA!

I met Mr. MFJ, K5FLU, once as well, at the 100th ARRL anniversary do. Wait?Think it was there, although it could have as easily been another time, like Hamcomm a bazillion years ago. Anyway, as others have said, a gentleman in very sense. Soft spoken, well spoken, as ?American as you or I. Oh wait. ? I?m also half Asian, on my mother?s side, so?umm...

I've long had mixed feelings about MFJ.  They have some very
interesting, innovative, and cost-competitive products.  However
sometimes the quality isn't there.  For example I have an MFJ antenna
analyzer that was intermittent until I fixed a poor ground connection. 
I forget the details, but as I recall the problem was partly one of
design.

Maybe because the discussion referenced what the clone referenced?

This will only be of interest to a few KPA500 owners  - those who don't think loud clicks/ticks/pops are acceptable.

In the message below I reported that I had lost interest in my investigation because the click/ticks had stopped.  That message is dated October 2018.   Late March the ticks came back and now, early April, they are back to the annoying level that I experienced in 2018.  What's different?  Room temperature and consequently the powered on but not transmitting temperature of the KPA500 is much lower in the winter months.

Although I lost interest in the investigation I continued to record PA temperature, heat sink temperature, and Z bracket temperature for every transmission I made.  That's a lot of data but  differences between summer and winter operating conditions may be interesting.   I plan to pick a few mid winter samples to compare with a few peak summer samples.

Has anyone else who is annoyed by KPA500 click/ticks noticed any correlation with room temperature?

73,
Andy, k3wyc

I found this quite annoying too.  My approach was to try to understand how the Z bracket temperature varied relative to the heat sink temperature.  I placed a thermistor on the front end of the Z bracket and another on the heat sink fin closest to the Z bracket.  I logged the standard PA temperature and these additional thermistor temperatures for every transmission I made (still do).   I established baseline temperature characteristics and planned to use this data to see if any mods I made changed the characteristics.


Surprise!  -  When I though I had enough data to move on to the next step in the investigation it stopped clicking.


Adding the thermistors only required removal of the front panel and the Z bracket screws were no touched.   It continued to click after the thermistors were added and then stopped a few weeks later.


The data show the rapid change in temperature is at the PA sensor only.  The heat sink and Z bracket change much more slowly and never have a large temperature difference.  Their temperatures do cross over though.


One problem with temperature logging is that I had no data, except for my test notes , on the clicks themselves.  I had planned to added some inexpensive sound detection modules and add this data to the logger.  That's on hold until the clicks come back.


It's really nice not to have the amp click continuously on every FT8 transmission.  I wish I knew what fixed it.

I've used many MFJ products and in have had very little trouble with any of them. For example, I make frequent use an MFJ-223 hand-held VNA -- it's versatile and does the job. I've also used their manual tuners, antenna switches, and portable/mobile whips. They have a very comprehensive product line that's really unique in the industry.

That said, I do have some suggestions for MFJ's engineering team on how they might improve their ATU.

You may have a dislike of MFJ products. But, that doesn't preclude the fact that their tuners work very well. They have been selling the K3 tuner for years. It doesn't seem the least bit surprising given the modular nature of the K3 and the long history MFJ has with automatic tuner technology. Maybe it's actually a complement to Elecraft that MFJ takes the K3 so seriously.

I had to re-solder the ground connection on the SO-239 connector 
on my MFJ antenna analyser. That's the only problem I've had 
with it. Getting a good connection on large chunks of metal is 
difficult, and takes a lot of heat.

I've always considered that the MFJ products meet their 
specifications, while the Elecraft ones exceed them. (I won't 
mention the time I ran 100W through a T1 tuner. It wasn't for 
long and the tuner survived.)

Folks, we exceeding the single topic limit number of posts and its also a long delayed repeat of a prior thread from over a year or two ago.

Let's close it in the interest of relieving email overload for our other readers. Feel free to search the nabble archive of the list for prior posts on this topic.

Its also outside of the list guidelines to criticize other manufacturer's products here.

Ouch. We did T1 tests at 50 W to make sure it could handle 20 W, and even that was an invitation-only event, with observers at a distance wearing safety goggles. How long it would survive a KPA1500 is left as an exercise for the reader. I'm imagining a soft blue glow from the toroids.

Actually keeping this thread open is a better thing...

It lets Elecraft users see what other options are available...

That said-- I know I would never add an MFJ item to my K3.  The fact 
Elecraft has allowed this thread to continue shows how open minded 
Elecraft is, and how sure of their product they are...

Come to think about it, I haven't heard mine click and pop in quite some 
time.? I doubt that it's seasonal, but that is an interesting twist.? I 
doubt that my room or the dormant equipment varies over +/- 2?F over any 
given 24 hr period.

The latest incarnation of this code is in the KAT1500, the ATU included in the KPA1500 amp. My colleague K6KR has done a great job of tweaking the algorithm to eek out that last tenth of an SWR unit on every match.

Jay,

Set the audio level on transmit so you have 4 bars solid and the 5th bar

There is a document on my website www.w3fpr.com that may help.  Scroll

Hi Barry,

The basic algorithm was developed for the KAT2, but it has morphed into several variations for our different tuners, including the T1, KAT1/2/3/3A/100/500/1500, and KXAT1/2/3/100. It's all about "pruning the search tree," to borrow a term from game theory.

I remember the bright yellow glow from the final in my Heathkit 
DX-40 when I forgot to connect the antenna. At least the plate 
didn't melt and the tube still worked.

I had a 100W K3 with no tuner and one of my antennas needed a 
tuner, probably for 30M. I used the T1, with the caveat that I 
would always lower the power when running through it. Well, I 
screwed up one time. I think what I noticed was that as my PSK31 
macro ran, the SWR kept rising.

I think I got the cores hot enough to change their magnetic 
properties. When they cooled off, everything went back to normal.

But as I said, Elecraft equipment tends to survive forays well 
outside their specs.

"It's all about "pruning the search tree," to borrow a term from game theory."

That always struck me as being a bit like trying to whack a pinata while blindfolded.     Why is it not possible to measure the complex impedance and compute the solution?  That should be a lot faster than any iterative method.  Sure, it needs a better detector but isn't Elecraft about elegant solutions?

I'll probably find the answer for myself in a while as it's on the list of things to try with my Kenwood/Elecraft interface (I have LP-100A complex load impedance available).

Pointers to any failed or successful attempts to do this would be appreciated.

Wayne is correct here.  If you don't use a principled approach to finding
the the best tuning solution, there are excellent binary searches that have
roots in game theory that are extremely good.  The optimum is to marry them
both.  The most successful commercial (militairy) algroithms start with a
phase-amplitude transfer function inversion to get very close to a solution
followed by a binary search to the final solution.

Subject: [Elecraft] Technical question on keying of an SDR radio
Message-ID: <B67BEF1A-41FB-4A1C-A937-D335C2AA45B8@mac.com>

If you look at various old circuit diagrams of ancient radios made from electronic circuits you find that the telegraph keying for the radio involves switching on and off the driving oscillator frequency or something similar.

However, with an SDR, you have other options and I have no idea how it is typically done.  For example, a digital signal can be produced that represents the Morse coding and this signal need merely be converted to analog and amplified.  Or, is there still an analog circuit being switched on and off for Morse code (telegraphy) keying with a modern SDR.

Can someone describe how this is done in a radio like the KX2.  And, is it done differently in the different Elecraft radios ? I presume that the K2 would have the more traditional sort of circuit but that is really just a wild guess on my part.

Hi Phil,

In the K2 the sidetone starts off as a squarewave created by the microcontroller. This is then shaped and injected into the AF amplifier. The sidetone is turned on/off at the same time as the carrier, which is generated by the LO (PLL synth) mixing with a gated TX BFO signal.

In our DSP-based radios (K3/K3S and KX2/KX3), both the audio sidetone and the 15 kHz 2nd IF carrier are created by the DSP. Their rising edges are shaped mathematically using what's called a "raised cosine" or sigmodal waveform. We experimented to find the ideal waveform equation, the result being the cleaned signal possible, with virtually no key clicks. The DSP can of course do other things like apply amplitude or frequency modulation, generate voice and data mode signals, apply ALC and audio EQ, etc. CW is just the simplest case of what can be done.

From the DSP, the digitized audio signal codes to a DAC (part of the audio CODEC IC), which then converts it to analog for injection into the AF amp. 

The 15 kHz 2nd IF carrier in the K3/K3S goes to a transmit mixer on the KREF4 module where it's up-converted to about 8215 kHz. It is then routed to the first IF mixer. The 8215 kHz signal passes through two crystal filters enroute mixer. In the KX2/KX3, the 15 kHz IF signal is converted to a pair of IQ signals (90 degrees out of phase with each other) to directly modulate a quadrature up-converter. The other input to the up-converter is a pair of balanced LO signals, again separated by 90 degrees. A result of IQ modulation is that one sideband is cancelled out, resulting in a single RF carrier at the desired frequency.

In all cases, the rest of the T/R sequencing involves the usual amplifiers, PIN diodes, filter switching, etc.

73,
Wayne

Hi,

it never occurred to me put anything non-E;ecraft to my fully loaded K3
radio.
I smept damn much for my K3 so would it be stupid and risky to waste it by
MFJ or even chinese crap.

I still have the first product MFJ ever put out, a CW audio filter that rang a little at the narrowest setting, but made my HW7 much easier to use.

Yes, some MFJ products are put together with less skill than some of us more exacting hams and a few of the MFJ products I have did require a touch of the soldering iron or the tightening of a grounding bolt but their products do work and for the lower cost are effective.  Look at any QRZ photo and you will see a MFJ product somewhere.  

I have most of the QRP Elecraft products and love them but Elecraft doesn?t offer all the products that MFJ does.  MFJ has a good warranty and they have honored it with me when needed.  Their problem solving team has responded to my emails and helped me when needed.  Elecraft is the Mercedes or BMW of the hobby.  MFJ is the Ford or Chevy.  My hats off and thanks to both fine companies for making this hobby fun for the past 59 years for this old retired guy.  Any ham that can?t or WON?T fix their MFJ (or other less expensive radio product) item isn?t a ham in the real spirit, but that is still OK. This IS A HOBBY and hobbies are supposed to help us relax and forget for a while the problems and issues of the day.  More healthier than going to the bar after work too.  Different strokes for different folks.

Again I will say (with my wife?s agreement) ham radio is much cheaper than a psychiatrist and less trouble than a mistress. My XYL always knows where I am and knew about my weird hobby  when we got married 45 years ago.

Nuff Sed,

My XYL (Sue, N2LBR) was also interested to try this.  She was watching 
closely as I was doing alpha testing for the KPA1500 firmware, and was 
wondering if using the network solution would provide guidance for an 
iteration scheme.

Her solution works even if the complex load impedance is not available. 
Based on the measured SWR straight through, the minimum and maximum real 
parts (load resistance) can be calculated, along with the corresponding 
(plus and minus) imaginary parts (load reactance).  This defines the 
"space" in which the solution exists.  A binary search proceeds by first 
solving the "exact" solution for the given real part (and the 
corresponding plus and minus imaginary parts), and then using those 
tuner settings (for L and C) to get a SWR with the actual load (which is 
modeled in her solution).  The algorithm proceeds by zeroing in on the 
iterated settings that have the lowest SWR.  It usually converges in 
less than 5 iterations to get a SWR less than 1.1:1, even for very large 
values of (initial, unmatched) SWR.

FYI Martin F. Jue is a graduate of Mississippi State University there in Starkville, MS.  He is a ham and a great supporter of ham radio here in the SE. Most vendors want big turnouts for hamfests and do not consider the smaller ones  for participation. MFJ has always supported our local hamfests here in the Birmingham area.

You miss the point entirely. Martin Jue is an American. He is not of a 
different nationality or culture. As to your other point, yes, humor 
does have victims. The people who have most often been the victims of 
much of our humor have decided they don't like it, which is their right 
as human beings. There is and will be plenty to laugh about. We just 
have to decide if we want to laugh at people because they are different 
or with them because we are the same.

Chuck,

I believe that is quite possible, but requires a more sophisticated 
measurement of the transmission line parameters that the Forward power 
and reverse power provided by a wattmeter.

Measure the parameters of the transmission line and calculate the 
network needed to bring those parameters to a 50 ohm non-reactive load.

It took a great deal of time to do the math when I was in college, but 
we did not have computers back in the early 1960s.
The principle is the same.

Ideally... yes, practically... no.  Given the load impedance and the ideal
impedance, you can always calculate a transfer function that is exact
(simply the path of movement on a Smith chart).  However, the question then
becomes how good are your measurements?  A high performance line section and
detector (log amp or other) has at best an error of +/- 1db in linearity and
resolution.  The step size of the tuning elements adds more uncertainty.
Bottom line here is that what seems easy can be difficult.

Wayne,

Thanks for the explanation.  I should have realized that it might have been documented.

My question was prompted by the appearance of a question posted to the "ham radio" formum of Stack Exhange on-line.  The OP (original post) of the question mentioned looking at a 1976 ARRL Handbook and seeing a circuit for the keying and wanted an explanation of how that circuit worked.  The answers (at the time I read the post) were somewhat simplistic and directed to the circuit that was shown in the question which of course was technology going back to the 1940s or before.  

Thus, I was curious of the improvements possible with DSP.

Thanks,
phil, K7PEH

Message-ID: <43bf68c7-e1a2-f31a-0783-2e5d478ad49e@verizon.net>

I'm a blind owner of a KPA500/KAT500 for several years, married to a 
TS-590SG.

The alarm that sounds when the amp faults (rarely) is impossible to hear 
when wearing headphones.

I've stuck a microphone  element near the radio and connected it to the 
mixer I use to put radio audio and computer speech into the  headphones.

On CW, and with the mic level set low enough, I could hear the alarm 
without  getting other shack noise, but not practical for SSB operation.

2 questions:
1.  Where does the sound actually come from on the amp?   If I knew 
where it comes out of the case, I would concentrate there.

2.  Is it possible to trigger the alarm with a software command or 
something?   I don't want to put the amp into intentional fault just for 
purposes of experimentation.

My amp faults infrequently, mostly 80/160 if ever, but  would still like 
to know if the alarm sounds.

Tnx for any thoughts, I get this on digest, so am on a slight delay.

Any comment, including this one is likely to bring on the slings and arrows.

With respect to ham gear, yes, roughly speaking you get what you pay for,
but sometimes marginal performance is much better than no performance.
Most of the MFJ stuff I have purchased has served the purpose, especially in
my younger years when more expensive alternatives were out of reach.
I also drive Fords & Chevys and not Range Rovers and Mercedes.

I should have added that the alarm is also available on the PC serial interface.  Interrogating the KPA500 with ^FL; will return the current fault value in the form ^FLnn; where nn is a 2 digit number indicating the current fault (00 for no fault).

It would be possible to use this fault report to vocalize the actual fault condition and play that fault message through your headphones.

The alarm  signal is available on  AUX1 connector pin 7 and is pulled low when an alarm is active.  I have it permanently connected to my data logger and have used it as a trigger for my storage 'scope.  It could be used to drive an external alarm of any sort that you chose.

Right on!  First, I have over two decades of experience with replacing
printed pages in Air Force Technical Orders.  What a PITA, but necessary. 
Today, those are distributed electronically and printed locally.  Often,
it's not possible to make a change that affects only one page since the
change, often an addition, pushes  information on to the next page.

Thanks to Elecraft (not all manufactures do this), we can annotate the PDF
versions with the latest firmware notes, ideas from this reflector, our just
our own pointers.  The PDF then becomes a current, searchable document of
great value!

As I point out in my ham radio presentations, it's 2019.  We do a lot of
things with computers now.  Join the 21st century.  The technology has
certain advantages, especially if you back-up your data.

Agreed, the Elecraft PDF's are very good, and I do edit my K3 PDFmanual 
with notes.? I've never printed it. Since the K3 is an essentially 
mature product [I haven't made a FW update in a couple of years ... I'm 
not even sure there has been a release in that period], nearly all the 
notes I add are "my" notes about things I've learned, obscure menu 
settings, and the like.

That said, in 2019, the term "searchable" is sometimes overrated. 
Searchable implies that you have some idea of what you're looking for.? 
Often, at least for me, a spiral bound book that lays flat on the desk 
and I can write in with a table of contents and an index is ideal.? I 
bought the spiral bound version of the KE7X book for just that reason.? 
I have a station journal [notebook - old engineering habit] and most of 
my annotations are to a volume/page where I've written about or recorded 
something.? It may be 2019 but the latest and greatest doesn't always 
replace the tried and true.? CW may be a good example. [:-)

New subject:? The quoted post below is all I got on the Elecraft list.? 
I don't know what prompted it.? It will lubricate the information flow 
on the list if the relevant posts in a thread are left in ... at least 
the one you're replying to.

Jim,
Before you order the FWKAT2, you should check to see what firmware version is currently installed in the KAT2.
I don't remember how to check the version number. It has been some time since I did that and found I had the latest version. 
If I remember correctly it is version1.07.
Don probably knows off the top of his head what the current version is and can guide you through the menus to find what version
Is currently installed in your KAT2.

Message-ID: <57614551-d16f-833e-9b20-b8d574f1fa97@nk7z.net>

A few months ago someone asked how to move the antenna signal coming in 
on the main antenna connector of a K3 to an external SDR via some 
connector in the rear of the K3.

The answer indicated connecting the SDR antenna to some connector in the 
rear of the radio, and pressing some number of front panel keys to route 
the signals from the antenna to the SDR...

Can someone point me at that post, or tell me how this is accomplished? 
The RF Signal flow on the K3 has always eluded me.

Also, is the output from the K3 at zero or close to zero when 
transmitting? i.e. is it safe for the SDR?

I don't believe the KAT2 tuning algorithm has changed since day 1, but 
Wayne might chime in with a verification.
I have never tried to check the KAT2 firmware version "from the 
menus/buttons"? If I needed to check it, I would have been in the middle 
of a repair, and it is easy to separate the two boards to check.
One option that needs the latest version is the K60XV, and support for 
60 meters needs KAT2 version 1.07.
Without the K60XV, version 1.05 will do just fine.

Connect a splitter, input to the RX Ant Out jack, one output to the
RX ANT IN jack and the other output to the Antenna input of your SDR.

Press the RX ANT button to activate the RX ANTENNA Out/RX ANT IN path.

Yes, the RX ANT Out/IN path is on the receive side of the T/R switch.
There is no RF (or only leakage) present in transmit.

Dave,

Look for a post by Bob McGraw.

In brief, it takes a TEE adapter and 2 short pieces of coax.  Put the 
adapter between the 2 pieces of coax, and then connect one coax to ANT 
OUT and the other to ANT IN.  The SDR is connected to the TEE adapter.

To get output to the SDR, you must set the K3 for the RX ANT.

If you are not interested in a multi-band input to the SDR, but only the 
K3 IF (for a panadapter application), then you can simply connect the 
SDR to the K3 IF OUT and set the SDR to tune 8.215MHz.

In both cases, the SDR will be protected during transmit.

73,
Don W3FPR

I agree with Joe in the procedure.?? As to using or the need for a 
"splitter", I don't find the input impedance of the SDR Play/RSP1 to be 
anywhere near 50 ohms. ? In fact it is much higher. ?? Thus the result 
of using a simple BNC "T" does not load the signal of the main 
receiver.? If your SDR receiver does present a 50 ohm input, then you 
can expect to loose about 3 dB of received signal.

And correct, the SDR will be protected when one is transmitting.

However, since the K3 receiver is relatively close to 50 Ohms, it
*WILL* load the input of SDRs with high input impedance - to the
extent that the SDR *can* lose 10 dB or more of sensitivity.  The
splitter works to protect the sensitivity of *BOTH* receivers -
if that were not the case why do you think Wayne bothered to include
a splitter in the design for the KRX3!

I don't understand the math behind this. The 50 ohm input Z of the K3 
terminates the transmission line. The SDR sees whatever voltage is 
across the K3 input. More to the point, why does it matter?? In most 
real world stations, especially below VHF, noise from the antenna is 
sufficiently greater than circuit noise that circuit noise doesn't 
matter. A ratio of 13 dB satisfies this condition.

I've been playing with this sort of setup recently. I have a K3 with a 
KXV3 and an SDRPlay RSP1. For my usage I find that theP3 is a better 
option and when I want the display on the PC I have the RSP1 connected 
to the P3 IF Out and use the software set to accommodate it is working 
at a fixed IF.

I tried connecting the RSP1 with a tee piece and two short pieces of 
coax to have a separately tunable third receiver but found a lot of 
unwanted responses on the SDR receivers display. Although I did not 
investigate very far, switching back to the much more acceptable P3 IF 
out technique in short order, I can only presume leakage from the K3 is 
the cause.

It could be that I had things 'set wrong' so please feel free to comment 
but although an impedance matching splitter might not be a necessity it 
seems to me at least that some sort of buffer ahead of the SDR might 
well be.

Martin,

Connecting the SDR to the ANT OUT/ANT IN jacks allows the SDR to see the 
enitire spectrum of the K3 antenna below the cutoff of the Low Pass filters.
Thaqt is apt to pick up any responses that are within the range of the 
SDR tuning, and if there are spurs coming from your antenna (which have 
nothing to do with the K3) then they will be seen.

Using the K3 (or P3) IF OUT will restrict the bandwidth to that near the 
K3 IF and may not show you those spurs - which are likely coming from 
devices throughout your house and your neighborhood.

73,
Don W3FPR

Bill,

Having spent time, over many years, piecemeal updating Jeppersen and CASA (the national aviation regulatory authority) pilot documents,  I regard it as wasted time I'll never get back.  I hope that Elecraft does not go down this path but agree absolutely that, these days, good searchable PDFs make life much easier. One thing that is always useful is the update register (already often used) and text markers indicating changes from the previous edition (often vertical bars at affected paragraphs).   

On the subject of the KPA1500 manual, I have much appreciated the additions to the original document but would like to see the block diagram expanded to make it more useful in terms of appreciating the amplifier topology and the relation to connectors, etc.  For example, the current very terse diagram does not show the pre-distortion coupler or its location and, if you hadn't had a spectrum analyser on the amplifier, you might not appreciate that it's not a direct output coupler.  Of course, I'd like to see the whole schematic but I understand that it must be a tricky commercial IP balancing act with a new product.

73, Peter (VK6HP).

Right on!  First, I have over two decades of experience with replacing printed pages in Air Force Technical Orders.  What a PITA, but necessary. 
Today, those are distributed electronically and printed locally.  Often, it's not possible to make a change that affects only one page since the change, often an addition, pushes  information on to the next page.

Thanks to Elecraft (not all manufactures do this), we can annotate the PDF versions with the latest firmware notes, ideas from this reflector, our just our own pointers.  The PDF then becomes a current, searchable document of great value!

As I point out in my ham radio presentations, it's 2019.  We do a lot of things with computers now.  Join the 21st century.  The technology has certain advantages, especially if you back-up your data.

Yes. This is the modern equivalent of those update methods of 
yesteryear, and a manual that is in any decent publishing application 
that can produce a pdf is trivially easy to update and to highlight 
changes. I consider such practice, along with a "change" list in the 
form of an appendix or separate document, to be the right way to do it. 
Any competent tech writer ought to be able make the edits and load the 
updated manual in no more than a half hour after the editing is 
complete. I can get a new or updated document on my own website in half 
that time if there's already a link to it on the main page, another 
10-15 minutes if it's a new document for which a new link is needed.

Hi
Although I've been a ham for nearly 30 years, I've been out the hobby 
for the last 25 of them and am now learning Morse again to get into QRP.

I have recently bought a KX1 and KX2 and would like to get the paddles 
for them, so if anybody has a KXPD2 or KXPD1 for sale please let me know 
(I'm in the UK if that makes any difference).

The KX1 has the ATU but only 40M and 20M, so again if you have a KXB3080 
for sale, let me know.

It's great to be back in the hobby and on the air (although I do feel 
like a novice, albeit with a Full or Advance licence!).

Thanks and 73s

Oh no! NOW you tell me that all these years that I have believed that I 
have been operating CW, it's really SSB!

(Disclaimer to avoid the otherwise inevitable explanations that a pure

I agree with your comments on the amplifier's manual Peter.  Getting tech
data right is a challenge.  I spent my last six years in the USAF at a
Major Command HQ where I would visit our primary depot twice a year to
discuss product improvement.  Tech data was a key part of those meetings.
Even though most of our troubleshooting stopped at the module replacement
level, we had schematics for each module.  One year while I was at the base
level I got to train a pair of Iranian Air Force sergeants depot level
troubleshooting and repair on a UHF ground-to-air transceiver.  My
background in ham radio gave me the needed understanding of electronics to
do that.

I will see Elecraft folks at the IDXC in Visalia this coming weekend.  I'll
likely have dinner with Bob, K6XX, the KPA1500 project manager Saturday
night.  I'll pass on your thoughts.  BTW, I've pushed my KPA1500 hard in
two SSB contests already this year.  It has performed flawlessly.

"I've pushed my KPA1500 hard in two SSB contests already this year."

I seldom connect a microphone so forgive my ignorance.  How is is possible to push an amplifier hard in SSB (phone) without exceeding legal limit peak output by a huge margin?

I'd understand "pushing hard" in RTTY or other digital modes but not SSB (phone).

Thanks, Joe. 

Works nicely and saved me the cost of something like the MFJ-1708B-SDR SDR
RF sensing T/R switch!

Sverre,

That answer depends ---
If you want to connect the SDR directly to the antenna, put the TEE 
between the ANT OUT and the preamp.
OTOH, if you want to have the preamp in-line for the SDR input, put the 
TEE between the preamp output and the ANT IN connector.

If you chose to use the preamp with the SDR, you may have to do some 
work on the powering and activation of the preamp.

David,

Elecraft has the KXPD2, and at last check also has the KXB3080 kit.
So the option that is not available is the KXPD1.

Doug,

Yes, thanks, you're right. I have the preamp set up to be active for the
higher bands 12, 10, and 6 m, and in the bypass position otherwise. I use
this to connect an old shortwave receiver (not an SDR) to my main antenna,
so I guess it doesn't hurt for it with the extra gain. But I'll try both
configurations, both before and after the preamp.

Not to worry, Victor. The really important part of generating and

It looks like the PS0 power off command still has the note about leaving the
Power On pin on the accessory connector grounded for at least 100ms to
ensure that no internal data is corrupted on the processor.

I'm wondering how hard it would be for the PS0 command to coordinate that
shutdown sequence without the need to manipulate the power on pin.  It sure
would make remote control much less cumbersome.

Yes, the USAF Technical Orders for a system could fill a bookcase if 
printed, and they were printed then.? I don't remember many of the 
volumes but the -1 was "How to fly the airplane" [or operate the radio], 
-6 was the Illustrated Parts Breakdown, I think -5 was the parts list.? 
There was usually a volume describing packaging for shipment of the 
myriad of modules in the system, and maybe one for storage requirements 
of various parts.? The well-worn joke was, "When the weight of the paper 
equals the weight of the airplane, you're cleared for takeoff." And, 
updates, in the form of page changes, could have life/death consequences 
if not done.? [see Boeing]

However ... tech data for a ham transceiver is light years removed from 
that environment and comparison really isn't fair or sensible.? 
Elecraft's manual, like all manufacturers', approaches the radio from 
the perspective of, "Here are all the controls and here's what they 
do."? There's some information about how the radio works, but it's not 
anywhere near exhaustive.? KE7X's books approach it from the perspective 
of "Here are the things you may want to do with your radio, and here's 
how to do them."? Again, there's information about what's inside and how 
it does it, but it's not exhaustive.? No ham manufacturer that I know of 
publishes page changes.

Most of what I write in my station notebook is stuff I've learned about 
my radios ... how to set up RTTY, how to switch from local to remote 
operation, anomalies such as the P3 span issue when changing bands via 
SW commands, TX/RX EQ and AGC settings, etc. It's not info Elecraft 
sends out.? I annotate the PDF manual with the volume/page in my 
notebook where the item is described.? For me at least, the Elecraft 
PDF, KE7X spiral-bound book, and notes in my notebook work fine.? I 
would have liked a printed spiral-bound K3 manual that lays flat on the 
desk, but the PDF works.

And? some of today's software applications {HRD}? have provision for 
MCW.? One must be careful how the interface between the computer and 
radio is constructed so as not to have anything in the audio path which 
would contribute to less than a pure sinewave signal.??? Actually this 
is exactly how AFSK and other data modes work.? A tone frequency is sent 
to the radio to produce the MARK signal and a different frequency tone 
is sent to produce a SPACE signal.

In all cases,? a clean signal path between the computer and the radio is 
found to be mandatory. ? Hum, buzz, clicks, pops and a mike left open 
are all a NO NO!

There's always a lot of discussion about measuring SWR, low SWR values, SWR lights not lighting up, etc. Here's something that might give you a better 'feel' for SWR.

Imagine that you measure your forward power at 100 W and your reflected power at only 1 W. You'd probably be very happy about this. Congratulations, your SWR would be 1.22 to 1.

Pause for a moment and let it soak in that an SWR of 1.22 is fabulously good. Once you get to this point, below which we're dealing with reflected power that's less than 1% of your power, or four-hundredths of a dB, it's not worth doing any more to your antenna system to improve it. No trimming, cutting, raising, lowering, hanging stuff from it, adding remote tuned things, nothing. You're done for the day and can now get on the air!

If the reflected power were 4 W, which would still look pretty small on the meter, the SWR would be 1.5 to 1.

A lot of people might be bothered by an SWR of 1.5, but really this is still very good and it's probably not worth going back up to the antenna to mess with it any more. Most importantly, the station on the other end cannot possibly hear the difference between your 1.2 and 1.5. 

At this point you may be saying, "Yeah, but my rig/amplifier/other thing isn't happy unless the SWR is below 1.5 to 1, so I would still have to do more work."

Okay, that's fine, but my point is that the absolute number 1.5 nonetheless represents a system that is working quite well.

Let's allow the reflected power to increase all the way to <gasp> 10 watts! At that point, your SWR would be about 2 to 1. Sounds pretty bad, but surely if you were stranded in the desert and had to use your KX3 and a wire to get help, you'd be happy to have a match this good.

Now, let's look at a certain type of SWR meter found in virtually every HF rig out there that uses a directional bridge, a diode as a half-wave rectifier, a filter capacitor, a resistor, and a readout of some kind - analog meter, digital display, or other.

These types of SWR meters are very common. There's one in the K2 (it's actually in the KPA100), one in the K3, and probably every other rig out there. And those Birds, MFJs and Daiwas have them, too.

This type of circuit turns RF voltage into a DC current, usually using either a germanium or Schottky diode, because these diodes have the best sensitivity due to their low forward voltage drops: 0.3 V for the germanium, and 0.4 V for the Schottky.

Let's say that our directional bridge, when 100 W is in the forward direction, delivers 10 V to the forward Schottky diode. In our example above of 1 watt reflected, the reflected diode would see 1.0 volts from the reflected port of the bridge. Since this is above the diode threshold voltage, the diode would be happy and operating in its linear region where we'd get about 1 volt out for 1 volt in. The meter would correctly read 1.22 to 1.

Now say you have your Elecraft rig set for TUN PWR = 10 W, so when you tune up, forward power is 10 watts, and if the SWR is the aforementioned 1.2 to 1, the forward power would produce a little more than 3 volts at the diode and the 0.1 watts reflected would produce about 0.3 volts. Here is where we run into trouble.

Since a Schottky diode doesn't fully conduct until we exceed its 0.4 volt threshold, expecting to get 0.3 V out for 0.3 V in isn't quite realistic. The diode's output voltage won't be zero, but it'll be smaller than expected, according to the nonlinear region around its "knee". I measured a Schottky diode and got about 0.09 V at that level. The meter would indicate an SWR of... 1.06 instead of the actual 1.22. This reading is false.

There are some things that can be done to the circuit to compensate for this error but I'm not sure how many rigs go through the trouble. Suffice it to say that measurement of very low SWR has a large amount of uncertainty because the detectors get more and more nonlinear as the thing they're trying to measure (reflected power) gets smaller and smaller. Due to this effect (and also due to directivity) every meter of this kind has a point below which SWR measurements are probably wrong.

When we see posts here by folks puzzled as to why low SWR measurements from two different instruments don't agree, this undoubtedly is one of the reasons.

I chose these scenarios deviously, to illustrate a kind of corner case, but I think you get the idea that errors always exist in any power measurement like SWR. You might say, "But my SuperDuper wattmeter is calibrated by aliens in a metrology lab deep inside a secret mountain in Nevada and I would bet my life on it." Great, cool, congratulations. But I'm afraid every last power meter has errors stemming from mismatch, directivity, nonlinearity and drift.

If you simply tune for minimum reflected power you should be good to go, and don't get too hung up on if the meter says "1.2" or "1.5" or "1.0". Remember, once you get down into this zone it's very likely good enough.

There was usually a volume describing packaging for shipment of the myriad of modules in the system, and maybe one for storage requirements of various parts.

Elecraft's manual, like all manufacturers', approaches the radio from the perspective of, "Here are all the controls and here's what they do."  There's some information about how the radio works, but it's not anywhere near exhaustive.  KE7X's books approach it from the perspective of "Here are the things you may want to do with your radio, and here's how to do them."  Again, there's information about what's inside and how it does it, but it's not exhaustive.  No ham manufacturer that I know of publishes page changes.

I annotate the PDF manual with the volume/page in my notebook where the item is described.  For me at least, the Elecraft PDF, KE7X spiral-bound book, and notes in my notebook work fine.  I would have liked a printed spiral-bound K3 manual that lays flat on the desk, but the PDF works.

My friend Al has described some interesting things about SWR measurement here. But not all power/swr meters behave this way. In fact the Elecraft W2 meter is in this class. The designer added an ingenious little circuit to the diodes to bias them into their linear region. What the smeans is that even at low power the W2 is giving accurate measurements not just of reflected power, but for forward power as well. this is important since the effect that Al describes is valid not just for reflected power, but also forward power at low levels.

There is one other things to watch for that actually negates Al?s suggestion to always tune for lowest reflected power. As an ATU tunes, it provides different loads to the driver. This will greatly affect not just the reflected power, but forward power measurements as well, to the point that we may measure very low reflected power, but the forward power is very low as well. Thus when we tune we really do look for both maximum forward power in conjunction with minimum reflected power.

One last point. The directional coupler measurements in the KPA500, KAT500 and KPA1500 are designed to handle large power levels since the devices are meant for high power. We don?t really try to be accurate at low levels. Indeed the KPA500 won?t even indicate power below 25 watts and the KAT500 needs something like 10 or 20 watts to work properly. This allows us to be accurate at high power levels and also avoid having to be concerned with the diodes workin in their non-linear mode. In other words, on these products you can pretty much believe the power levels the device is showing when it is showing them.

Al, thanks for a nice write-up.

73!

Subject: [Elecraft] D13 voltage test high?
Message-ID: <1554843267500-0.post@n2.nabble.com>

Manual says D13 (banded end) should show between 90-150V, mine measures 178V

... says U4 pin 8 should be between -5 to -25 V, mine measures -30V

Still going through the receiver tests, up to the dual-supply tests and all
seems well, so should I be concerned about those readings?

The diode's output voltage won't be zero, but it'll be smaller than expected, according to the nonlinear region around its "knee". I measured a Schottky diode and got about 0.09 V at that level. The meter would indicate an SWR of... 1.06 instead of the actual 1.22. This reading is false.

Suffice it to say that measurement of very low SWR has a large amount of uncertainty because the detectors get more and more nonlinear as the thing they're trying to measure (reflected power) gets smaller and smaller. Due to this effect (and also due to directivity) every meter of this kind has a point below which SWR measurements are probably wrong.

Since no one has answered your question. I will venture a
supposition that many know but few will speak out.
And some still remember their CB days and the erroneous
advertising saying the power is lost.
Reflected Power flows back down the feed line and is subjected
to the normal feed line loss. It then is "reflected" back toward the
antenna, again subject to the feed line loss, where some of it is
radiated and some reflected again.
This continues until the power is dissipated. The book "Reflections"
 has a very good but somewhat technical explanation.
Therein also is the reference to forgetting about striving for the
"Holy Grail" of 1:1 SWR.
And concentrating on getting it low enough that the transmitter will
supply full power output. Also using the best low loss feed line and
proper matching when possible of the feed line to the antenna.

Well, the reflected power is created by a "virtual transmitter" at the 
feedpoint of the antenna and heads down the coax which has a surge 
impedance of Z0 ohms.? It meets the SO-239 at the TX and sees an 
impedance of Z1, the impedance presented by the PA and output filters.? 
If Z1=Z0, the power is dissipated as heat in the PA and associated RF 
circuitry.? If Z1<>Z0, some is dissipated and some is reflected, where 
some is radiated, and some is reflected [virtual transmitter again].? Ad 
infinitum, and when forever is over, it is all gone and everyone lives 
happily ever after.

SWR and all the associated measuring equipment and concern with it only 
became an issue when: 1) Coax replaced parallel lines and; 2) Resonant 
output circuits were replaced by solid state amplifiers with 
non-resonant filters.? When I sat for the Extra in early 1956, the only 
question that involved standing waves was one about how Lecher Lines 
could be used to measure transmitter frequency.

It's important today but calculating it hasn't changed.? At 10 W, a 2:1 
SWR will probably work ok.? At 1500 W, a solid state amplifier may not 
be happy with the voltages developed at its output connector.

I agree except that even at 500KW a 2:1 or greater is the norm with open wire line.

For a slightly different answer, take a look at my website www.w3fpr.com 
article on Antennas, Transmission Lines, and Tuners.
You can also find that same article preserved at

What gets me is that Ken was not commenting on a race but a culture.  He was completely wrong in his assessment of the culture to which the head of MFJ belonged, but that?s another issue.  It should not have been implied he was a racist for that comment.  An apology is due, IMHO.  The word ?racist? is thrown around too frequently today in ways that are on the verge of rendering the word meaningless.  At that point real racists take cover under the umbrella thus created by the misuse of the term.  That?s very unfortunate, because real racism is hideous and needs to be forcefully countered and confronted everywhere it raises its ugly head.

As a counter to those who are asserting that SWR 1.5:1 is a good enough match for an antenna system I offer measured data for the KPA500.

At 14.005 MHz my KPA500, when connected to a 1.44:1 SWR load (R37, X9), had a PA dissipation of over 500 watts when producing 400 watts RF output.   When the load was changed to 1.30:1 (R39, X3) the PA dissipation was about 410 watts.  When the load was changed to SWR 1.07:1 (R49, X3) the PA dissipation was reduced to under 400 watts.   (The plots are far more informative than a text description but I can't post them here).

If you don't mind your KPA500 running hot, and are prepared to accept it shutting down with PA DISS fault, then 1.5:1 SWR may be good enough for you.   I'd rather know the complex impedance of the antenna system load and avoid loads that result in high PA dissipation.

Assuming that the correct load is 50 Ohms, load with SWR of 1.5:1 could be 33
Ohm or 75 Ohm. Or something more complex.

The load of 33 Ohm would cause bigger dissipation and the load of 75 Ohm
less dissipation but also less power. 

Three options here. First, spend hrs/days optimizing your antennas. Second,
use antenna tuner. Third, accept inefficiencies. Personally, I would not
consider a solid-state amp without a built-in tuner.

Not sure who had the modification for the Vibroplex Code Warrior JR posted but THANKS!

I removed the screws holding the paddles in place and replaced them with brass screws and washers (I used nuts as the hardware store did not have brass washers) and I now like the paddle.
I also used some nail polish (wifes?) on the bottom to hold them in place as they are ?slightly loose? to give me a good feel.  I also noticed I ?had? washers underneath the paddle as well.

It has been a frustrating experience with the dits on my Code Warrior JR since new but replacing both screws and adding washers gave me a new paddle.

And then use the lowest loss feedline one can afford and install.  This minimizes the increased loss due to SWR.

A typical transmitter does not reverse terminate the transmission line 
with its characteristic impedance, so most of the reflected power gets 
re-reflected as forward power.  Reflected power isn't necessarily lost 
power.  At least at lower frequencies, it is likely to present a much 
higher impedance.  A final that did accurately terminate the line would 
be rather inefficient.

A more important issue with SWR is high SWRs can cause clipping (you 
need a larger voltage swing if the load is higher (assuming purely 
resistive for the moment), or take it outside the safe operating area of 
the output devices.

Those may cause problems at quite low SWRs, but they actually depend on 
the complex impedance, so on some parts of the Smith chart circle you 
may be completely safe, but on others, you might kill the finals.

Since when did nationality = race?  Why do you assume Ken?s comment was based on how Martin looks?  He may have never seen a photo of him.  I certainly haven?t, that I can recall.  His name sounds like it?s Asian.  Is his ethnicity Chinese, Japanese, Korean?  I have no idea.  Ken may have assumed, I gather incorrectly, that he was an immigrant from one of those nations.  Each of those nations certainly have different cultures, with different sets of cultural norms.  Ken made a very awkward statement.  Not one I would make. But, I think branding it as racism is more in the eye of the beholder then the pen of the author.  73 de Carl N8VZ

Or 10:1 or even 20:1.? However ... there's always a "however" or a "but" 
... it doesn't matter.? The dielectric constant of air [the insulator 
between open wire conductors] is very close to 1 whereas it is much 
larger for various forms of coax.? Very high SWR creates very high 
voltages along the line.? The energy storage with high dielectric 
constants is much higher than with air, and dielectric losses go up 
dramatically.? In prehistoric times when we used vacuum tubes and 
resonant tank circuits, we coupled power to the line with a 2-3 turn 
link coil adjacent or in the middle of the resonant tank.

If the line exhibited reactance, it detuned the tank which we just 
retuned to resonance ["Dip the plate, increase the coupling, repeat"].? 
The PA tank circuit became a thoroughly mis-named "antenna tuner."? It 
didn't matter what the SWR was on the open wire transmission line, and 
in fact no one paid any attention to it.? Then flexible coaxial cable 
was invented.? It was much more convenient than open wire line, however 
in reasonable physical sizes, it had very low characteristic [surge] 
impedances ... 50 and 75 ohm impedances were the result and now, SWR 
mattered.? The dielectric constant inside the cable was very much 
higher, and the higher voltages from high SWR resulted in much higher 
dielectric losses.

Then, someone invented the Pi-network [for all of you with fingers 
poised over the keyboard to pounce on my description of history, relax 
and breath deeply.? I'm making some of the non-technical stuff up to 
help hold your attention].? The Pi-network would transform the 50 or 75 
ohm impedance at the end of the coax to the several thousand ohm plate 
circuit impedance of the PA stage and power would flow to the antenna 
unimpeded.? It was at this point that sales of SWR indicators soared, 
SWR became a household abbreviation in the ham community, and an SWR of 
1.000:1 became the Nirvana of ham radio.? It has been thus ever since.

As electronics progressed [?] from the vacuous to the solid state, SWR 
took on an enhanced importance since the solid state was far less

And for that reason as Roy stated, those components that are rated 
"legal limit" are done so under MATCHED conditions.??? Use a legal limit 
component in a condition where SWR is 2:1 or 3:1 or higher and one is 
likely to find it becoming a smoke generator at legal limit or even less.

Case and point, the KAT500 ATU is rated at 600 watts, 3 - 30 MHz, 5 oh

Subject: [Elecraft] SWR and Power Output
Message-ID: <EFCEBF50-2C7B-4EED-B30D-8DF4D5F18ACF@sbcglobal.net>

The reason SWR should be of concern is the effect it has on what is presented to the solid state output device(s) in your radio. 
The output power and final stage current is determined by the load presented by the antenna/tuner and the output matching network. 
The output power is, P= supply voltage squared divided by 2xR(load). A 2:1 SWR could present a load either half or twice the design load for the 1:1 (50 ohm) SWR match or some where in between those two points with a complex impedance being presented to the output device(s).
Thus, the output power delivered by your radio and the final output device current and efficiency  is directly related to the "match" presented to your radio by your antenna and/or tuner.

I believe I run the highest SWR of anyone here. It is close to 100:1 in 
normal operation according to EZNEC (I have never tried to measure it).

The line is open-wire line made with no. 12 (2mm) wire, only about 10m 
long. The highest SWR is on 40 meters, and I calculate the loss as 
around 1 dB. I calculated the peak voltage at around 7 kV. You know how 
the specs on vacuum relays have to be derated for RF? Believe them.

After using various more or less complicated matching arrangements, I 
settled on an old Johnson KW Matchbox. It does the job on all bands from 
40 through 10m, with just a little external help on 30m. The antenna is 
a simple rotary dipole whose total length is 10m.

I think that this was covered. You don?t run a solid state unit into a mismatch. The antenna tuner in effect takes the place of the output network that existed with tube rigs.

At a given operating point, there is always some load Z that will minimize 
amplifier dissipation (and probably another that minimizes IMD).? The problem 
is, we don't normally know what it is, so guessing about it is pointless. Hence 
specs like X watts into Y SWR (nominal).

Andy provided three data points. Changing the sign of the reactance will leave 
the same SWR, but more than likely different amplifier response.? In fact, 50 
+j0 might not be optimum.?? Who knows, maybe some point on the 1.5:1 circle on 
the Smith chart is better :-)

Adding to this uncertainty is the fact that with the typical measurement 
circuitry in our PAs and tuners, we don't know the real SWR either.

I, and others, discussed this in an earlier thread 
:http://elecraft.365791.n2.nabble.com/K3-SWR-Numerical-Indication-td7643839.html

It was a feeble attempt at humor, given the nearly countable infinity of 
posts here on baluns over the last few years including but not limited 
to what they are, what they aren't, how they work, do they even work?, 
and do they even exist at all.? Perhaps my attempt was more feeble than 
I thought. [:-) And, yes I know that "near infinity" is meaningless.

Subject: [Elecraft] K2 filter alignment problem
Message-ID: <6007f846-8e61-7e6f-5f8c-99e371dc8798@verizon.net>

I have aligned my K2 crystal filters with Spectogram many times, but 
this time I've run into a problem that I can't figure out.

Using Don's [and the manual's] instructions, I can align F1,F2,F3 in 
decreasing bandwidths. All works as per expectations. On F4, the 
alignment goes "ok," [as per Spectogram] but when I use it with 
on-the-air signals, the signal "disappears" and shows up about 900 cps 
lower and in "reverse" orientation [BFO on opposite side]. When the 
signal disappears, I can change filters [F1/F2/F3] and it's right there 
where it should be with the bandwidth getting narrower as expected. But, 
switching to F4, it's gone. I have tried changing the BFO frequency 
throughout its whole range when in F4, thinking that I've aligned it on 
the "wrong" side. No luck. I'm stumped. Any and all suggestions welcomed.

Dear all, 

Can anyone comment on this 

XV144 internal transverter. 

Any difference in performance on 144MHz when installed in K3S or in K3 serial number about 1250?

Subject: [Elecraft] KAT3A 160M issue
Message-ID: <5CAF36AD.31368.16F45BA@Gary.ka1j.com>

I have been having unusual transmit issues 
with 160M, SWR issues I have long thought 
was antenna related. 

Last night I found when transmitting on 
160 the SWR on the LP-100 suddenly showed 
9.1 and the same with the remote sensor 
for the P3 but no output shown on the P3 
wattmeter. I connected a dummy to the amp, 
same issue. attached it to the back of the 
K3s & the same issue with the autotuner 
unable to get a good match (HIGH SWR).

This was only on 160, all other bands were 
fine.

I pulled a KAT3 from my backup K3 and all 
now works well, 160M had what showed as a 
beautiful SWR & the amp was very happy 
showing a 1.2 SWR

Before I call Elecraft & take up their 
tech time on a phone call, is there 
anything I might check on this KAT3A 
regarding a 160 failure before starting a 
RMA? The 160 toroid looks fine and no 
obvious issues show to inspection.

thanks & 73,

I'm experimenting with portable antennas at the moment for my KX3 and,
rather than cut the 80m legs of my link dipole to get an antenna that
resonates on 60m, I've experimented with running it off centre. I've found
what looks like resonance at the right frequency range, based on low return
loss.

http://m0rjc.me.uk/screenshot_20190411-132334/

The problem is, that impedance is low. I guess it's being transformed down
by the 10m of feed line, as normal wisdom for an off-centre feed is high
impedance due to the lower currents and higher voltages towards the ends of
a half wave antenna. Considering a velocity factor of 0.66 that feed line
is about 1/4 wavelength long!

Presumably the KXAT-3 will tune this, but do I lose efficiency by having
what would be higher currents in its circuitry?

Richard,

Try widening the FL4 filter out to 0.2 instead of 0.1.  With the more 
narrow setting there is often more attenuation with little actual 
reduction in width.

When aligning the BFOs, pay attention to the DAC values (and/or 
frequencies).  The ones for CW must be less than the filter center and 
those for CWrev must be greater than the filter center.  Normally the CW 
FL4 will have a BFO frequency near 4913.12  and for CWrev a frequency 
near 4914.3 kHz.

Make certain when aligning the filters with Spectrogram you use a source 
of wideband noise.  If you are using 'antenna noise', be certain there 
are no signals nearby.

Don W3FPR

If I had a problem with a KAT3, the first thing I would check would be 
the relays.
But where is the LP100 connected? It must be AFTER the KAT3, so a 
problem in the KAT3 would not change the SWR indicated on the LP100 (or 
the P3 for that matter).
Maybe you had a cable, connector, or antenna problem that damaged the 
KAT3 somehow?

In many instances using a balun, not for balanced to unbalanced 
applications, but for impedance transformation application is 
suggested.?? Use a 4:1 as a 1:4 in order to get the low Z to a higher 
value.? In most tuners, the low impedance range has more loss than the 
high impedance range.?? I recall that Elecraft makes just this item.

Richard,

More specifics are needed for a good answer.
The easy way to do it is to measure the impedance at the shack end of 
the feedline with an antenna analyzer.
Yes, you moved the feedpoint away from center (but did not say by how 
much) and the voltages will be higher and the current will be lower at 
the frequency where the radiator is resonant, but it is an unknown at 
other frequencies.
The quarter wave feedline -- at what frequency is it a 1/4 wave?
It will certainly act as a matching transormer, but more detail is needed.

As I indicated, measure it with an antenna analyzer to see what the real 
situation is on 60 meters.

The theoretical loss will because of currents through the inductors will 
increase, but the practical consideration for the KXAT3 will be minimal 
as long as the SWR does not exceed 10:1.

73,
Don W3FPR

Don...

Bingo! The F4 filter setting was too narrow, as you advised. Also, the 
BFO was somewhere off from where it belonged. Once I got those two item 
adjusted everything worked as per specs. I was impressed that the BFO 
values that you quoted were more or less right on. Seems like you have 
some experience with the K2 :-). Thanks much for your time and 
attention, as always. Have a good day.

Yes, if they are pet collars, door cams, keyfob locators, or mood-sensing personal heating appliances.

Otherwise I'm not sure. What did you have in mind?

Many of our customers are shrugging off the lack of sunspots and boldly going places with their QRP gear and AX1 antenna. So, a quick survey for those who have ventured thus: What's your best DX? 

This feedback will be useful as we consider future antenna products.

Subject: [Elecraft] [T1] Newly assembled T1 inop
Message-ID: <1CB865AB-B6A3-4C95-A740-DBC98D373564@gmail.com>

Just completed an Elecraft T1 ATU. I built and used one several years ago and wished I hadn?t sold it, so built another one. But it?s not working. When I plug-in the (tested good) 9v battery, the yellow LED blinks 4 times (not mentioned in the manual that I can see), but there?s no response to any other button pushes. I went back through all the tests in the assembly manual and they are AOK. I followed the voltage source through the 6v regulator and that?s ok, although the regulator output reads 5.0v on my DMM. Is that too low?

I will confess something. When I inserted the 28 pin MCU into its socket, no matter how I tried, I could not get it in all the way. I?ve socketed dozens of ICs  and never had this happen before. The instructions insist on getting it in so that the ?shoulders? of the pins contact the socket. I was about 1/16? short of that. So I clipped about that much off all the pins and got the pin ?shoulders? to contact the socket. I could not have gotten the little control board to fully seat over the MCU without doing this. But I may have ruined the MCU by doing this...

Any help appreciated!

Message-ID: <9c056211-edfd-1928-d270-34dc9514e2cd@nk7z.net>

Hello,

I am considering the use of a remote base type of setup to get away from 
the RFI in my area.  I have finally given up on trying to fight it, and 
want to move the rig away from the city, as opposed to hunting down and 
correcting every new RFI source endlessly.

My station consists of a KPA500, P3, and K3.  I am using a P3 external 
keyboard, running an external computer to do FT8, and finally CW via the 
radio, not using a computer.

Is there a system which would allow the same functionality I now have, 
remotely via the Internet?

So far Hawaii from Texas. Operating with the AX1 running 5 watts on on
phone during the CQ WPX SSB contest.  Using the antenna mounted on my third
floor balcony.  Need to take it out and get a little higher elevation and
see what happens.  The KX2 was an impulse buy, I like it but need to use it
more for sure.

Remote operation is certainly feasible, but it does introduce new considerations/tradeoffs.  I?ve been operating remote since purchasing my K3 system in 2014 specifically for remote operation.  About 80% of my operating is done remotely.  

1.  I use a K3/IO-mini with the Remote Rig setup to control the K3 because the K3/IO-Mini front panel is the same as the K3 and I avoid the need to use a computer to control the K3.

2.  I control the KPA-500 using the Remote Rig RC-1216H as it provides a web-based front panel that matches the KPA-500.  As it is a web-based interface, I can use any device (Mac, ioS iPhone or iPAD, Windows PC) to access the KPA-500 front panel.

3.  I have the KAT-500 Tuner which I am forced to run the Elecraft Utility to manage it.  I have a serial-to-ethernet converter in the ham shack and my network at the ham shack location is linked to my location (through VPN)  so that the Windows computer at my location will connect to the KAT-500 serial interface.  

4. I do not have access to my P3 operating remotely.  Others have installed video cams aimed at their P3 to forward imagery to their location to see what the P3 is displaying.   Others who do this may have some thoughts on managing the P3 remotely.    

5. Antenna selection is done using an Antenna Genius from 4O3A.  There are a total of 8 antenna ports and two radio ports.  The K3 system is connected to Port A and communicates with the Elecraft through BCD to select the antenna based upon the band that the K3 is set (e.g. 10-15-20 goes to the tribander, other bands such as 40 and 80 to an EFHW with additional ports for a dummy load and future 6M antenna).  The Elecraft interface to the AG is based upon Y-boxes developed by Bob Wilson, N6TV.  See:  https://www.kkn.net/~n6tv/Y-BOX/ <https://www.kkn.net/~n6tv/Y-BOX/>

Antenna Genius Port B is used by my Flex-6700 Antenna Port ?1? and associated hardware.  The Flex communicates directly with the AG through a CAT5/Local Area Network connection.  

I also use the AG utility but it can only run in Windows and works with a remote connection through VPN.  

My primary use for the K3 is voice communications, so I have not delved into digital modes (yet).   My presumption is that operating digital may require using the PC in the ham shack to do the actual digital operation while connecting to the shack PC via Team Viewer or other remote access software to manage the process.  Again, others who are actually doing digital modes while operating remote may have specific suggestions.  

Overall, I?ve been very pleased with the K3 setup operating remotely.  The Codec(s) used by Remote Rig require very low bandwidth while providing excellent audio.  As my station is located in rural SE Georgia where internet access (at best) is typically 768 Kbps upload/20 Mbps download, I have no problems running the K3 remotely while using SSB.  While I also enjoy the Flex (particularly since SmartSDR v2 was introduced that allows remote connection), slow internet is better handled by the K3 system because of the Remote Rig audio Codecs and the lack of panadapter/waterfall display that can take up bandwidth.  

FWIW,

Barry Baines, WD4ASW

So far Washington State from Georgia on 20 m running 10 watts from a picnic table near the top of a dam on a POTA activation. I had the AX1 connected directly to the KX3 with the bipod and was using the supplied counterpoise.

Looks like I need a replacement KAT3A 
tuner. Weighing the cost of 
repair/replacement, I wonder if anyone has 
one that they did not use, are not 
needing?

If so, please contact me off list with the 
details.

 I worked France and Germany during the recent ARRL CW contest from Utah.? What makes it even better is I was indoors at my kitchen table using my KX3 running 10 watts with the counterpoise wire on the kitchen floor.? I have also worked Hawaii, Mexico, the Caribbean and all over the US on 20 meters on CW from the same location because I was too lazy to set up an outdoor antenna during very cold Utah winter weather.? My first contact after receiving the antenna and attaching it to my radio was XE2X in Mexico (CW from my kitchen table running 5 watts).? Even my wife, who isn't a ham, was impressed ;-)? The AX1 has been the perfect complement to my KX3 and KX2 for casual quick deployment.

Message-ID: <6ABABF25-587B-4A4C-8191-D7DE0E9BCE13@gmail.com>

Has the support for a 630m xvtr band via other than Test mode made it nearer the top of the list for the K3s?

Presumably this would have an IF of zero and be able to use the DIGOUT0, LP setting and the XVTR IN/OUT jacks. 

Thanks

Found the problem! As many would guess - it's a solder problem! A tiny
splash of solder in a random location shorted one of the remote control
lines to ground!

Hey folks?
I have an unusual (I think) problem.  I have a KX3 that I have used the KX3 utility software with several times without issue.  Today when I start the software there is no COM port to select.  In the bottom left hand part of the KX3 PORT window is says Serial Port is Closed. (I?m using the Elecraft USB cable for the KX3).

I can?t get it to work.  I can control my Kx3 with DXLabs using the COM port no problem.  I can use the Elecraft Frequency editor with no problem.  I can use WinLink Express no problem.  But when I start the KX3 utility software I can?t select a COM port ? there are none listed.

Here is my troubleshooting so far:
1. I know the COM port is there ? it works for other software
2. I used the FTDI driver removal tool and uninstalled the FTDI drivers 
3. I uninstalled the KX3 software
4. Reinstalled everything ? but the issue remains

Any ideas?

Windows told me the COM port was closed, even though it showed up in device manager.
A reboot fixed it.

Hank,

Re-boot the computer - it seems all the problems are in your computer. 
Oh, yes, power cycle the KX3 too, but that will not likely make a 
difference.

After rebooting the computer, look in Device Manager to see which COM 
port your computer assigned to the KXUSB adapter, and use that COM port 
in all your applications as well as KX3 Utility.

Windows sometimes changes the COM port (in its infinite wisdom) for you.

Hank,

In that case, the next step is to download and install the latest copy 
of KX3 Utility.

Hank,I had a similar problem earlier this week following a Windows update.? ?The COM port showed up in Device Manager, but the software? package I was using (not the KX3 Utility) couldn't talk to it.? Within a day or so, there was another Windows? update,? and then everything worked fine.Sometimes it seems like an update breaks something, and a follow on update fixes it.? Not the first time I've seen that happen.Mark,KE6BB

I received a few off list replies and  have updated the report to add the following:


Note - the displayed results are for a test with a well matched dummy load.  Efficiency and PA dissipation are dependent on frequency, output power, and the antenna system load.  Higher dissipation and lower efficiency may be seen in normal operation.

Hello Again,
This Om is still having a problem with TX .
Windows 10 on a HP Envy
I have tried to do everything that has been recommended with no luck.
I am using Codec sound card for both TX and RX
The RX has a slider that I can move.
The TX has no slider and it is moving up the scale at about 15-20 (just a
guess) no numbers show up.
Trying to do FT8
I set the radio to Data and when I TX it switches to USB. I believe this is
normal.

PS
SSB I am having no issues.

Thanks again for any thoughts.

Good Evening,

all.? I found out it is a large part of their diet.? No wonder it 
doesn't hang close to the ground.

For Sale working and quite accurate AADE  model IIb L/C Meter, the last 
version produced.  The designer passed away in August of 2015 and this 
extremely nice L/C meter from "Almost All Digital Electronics" is no 
longer being made or readily available.

Somehow I wound up with two of these and only need one on the workbench. 
  I'm trying to amass enough funds to buy a larger 3D printer than the 
one my wife bought me for my recent birthday so am paring down a few 
items I no longer need in the shack.

I believe these sold for around $105 new.  The unit is in excellent 
working condition with only minor cosmetic marks on the faceplate and 
case.  I'm asking $85 shipped anywhere in the US & posessions and a 
printed version of the manual will be included.

PayPal preferred.  Please contact me off the reflector to say you want 
it or for further information.  Photo available on request.  First "I'll 
take it" or reasonable facimile gets right of first refusal based on 
date/time of the sender's email message.

Subject: [Elecraft] K3 no TX, no RX, and solved
Message-ID: <cdcaf732-7b82-c2cc-5ff9-3e343c6d466b@xs4all.nl>

Just for sharing.

Case:
K3 #1255 (loaded)
Has all mods during the years and upgrades to K3(s) except for USB port

Problem: no TX and no RX (not on main, not on sub)

Analysis:
1. Connecting a panadapter on the IF out: IF signal of main RX is there 
and and signals are where they should be, so VCO of main RX (as first 
oscillator) is working all right
2. The two pre-amps, attenuator, and antenna switches working fine 
(checked on panadapter)
3. RF gain to minimum moves S-meter to max on Main- and Sub-RX (normal)
4. All RX DSP functions seem to work on the little noise that is audible
5. Audio spectrum analyser connected at audio output shows that IF 
filters do not influence the audio bandwidth, only the DSP does. 
(fiddled with the filtersettings in the K3 utility)

Conclusion:
There's a hick-up between the 8.2MHz IF and the entrance to the DSP, 
seems like 2nd IF of 15kHz is down. No mixing signal form 8.2MHz to 
15kHz? That one sits on the KREF3, where all those TMP-cables come together.


Checking the reflector...
Found this line: 'TMP-cables are a class by itself' , and indeed it is 
so.? :-)

Repair: Refitting all TMP-cables

Result: K3 is playing as normal again and PA3A is a happy man.
(By the way, this is not the first time in the life of #1255 that its 
TMP-cables needed a little push.)


Cheers and 73 to all,

Arie Kleingeld PA3A

Hank,

Installing KX3 Utility will do nothing for changing what your computer 
does about COM Ports vs USB port assignment.? It is now apparent that 
your computer is not properly recognizing the FTDI USB to Serial adapter.

Download and install the FTDI drivers from the FTDI website.
What you are trying to deal with is an FTDI USB to Serial adapter.? Just 
because the KXUSB cable is sold by Elecraft does not change that fact - 
the FTDI chipset is not an Elecraft device, but an FTDI device even 
though it is included in the KXUSB.

Bud,

The Field Test of the K2 started in late 1998 and ended in 1999 (I 
believe May) with the first production K2.

I would assume SN 2514 was shipped about 2002.  That is a Rev A K2, and 
if not installed, would benefit from the A to B upgrades.  The boards 
were re-done to REV B to incorporate all the prior upgrade mods at SN 
3000.  A serial number 2514 would have to be physically instected to 
determine which upgrades (different from options) have been installed.

I have done all of those things and no change.  As I said every other piece of software that needs the KXUSB grabs it and uses it fine ? just not the utility software.

There is something to the driver installation ? it shows as incomplete, but reinstalling the FTDI drivers from the FTDI website still does not fix the problem.  There is still an event message saying that the installation did not complete.

I realizer this is not an Elecraft issue, I?m just looking for help.

Hi,
Sometimes driver software can be a pain...
Try this.
1) Open the device manager and select the comport by right clicking on it.
2) Check the box to delete the driver software and uninstall.
3) Unplug the USB cable.
4) Reboot
5) Next run the FTDI driver installation.  When prompted or when complete, plug the USB cable back in.
Sometimes, windows will keep reinstalling the same driver if the files have not been deleted.

I have done all of those things and no change.  As I said every other piece of software that needs the KXUSB grabs it and uses it fine ? just not the utility software.

There is something to the driver installation ? it shows as incomplete, but reinstalling the FTDI drivers from the FTDI website still does not fix the problem.  There is still an event message saying that the installation did not complete.

I realizer this is not an Elecraft issue, I?m just looking for help.

Hank,

Installing KX3 Utility will do nothing for changing what your computer does about COM Ports vs USB port assignment.  It is now apparent that your computer is not properly recognizing the FTDI USB to Serial adapter.

Download and install the FTDI drivers from the FTDI website.
What you are trying to deal with is an FTDI USB to Serial adapter.  Just because the KXUSB cable is sold by Elecraft does not change that fact - the FTDI chipset is not an Elecraft device, but an FTDI device even though it is included in the KXUSB.

73,
Don W3FPR

Hank, I cannot offer any technical help but I can offer empathy, be it ever so OT.

I often have the same problem with N1MM.  Some days it finds a port; some days it doesn't.  There is no correlation that I can discern with anything I do -- including cussing, fiddling, supplication, offering to negotiate, lunar phases, making contributions to charitable causes, turning devices on and off . . . 

I am convinced the digital world has escaped its creators and created an unruly universe of its own.  Hamlet was prescient:  "There are more things in Heaven and Earth, Horatio, than are dreamt of in your philosophy."

In bocca al lupo,

Ted, KN1CBR

Can I just add that at the stage that says reboot, you should really shut down the machine, wait a bit, then
Restart. Sometimes a USB port is not physically but just logically reset by a reboot. 

I hope this helps

On the FTDI site there is a removal tool. Use it to wipe away com port drivers. Then re-install the FTDI drivers for your KUSB or KXUSB cable. 

Good luck!

Okay?some weirdness, but I can get the software to work.  Here is what I have done (some help from you guys, some help from the IT guys where I work, and the internet).  It?s a little complex?

Configuration 1: My laptop is connected via USB to a PK-232SC+ which has a 2 port USB hub built in ? my KXUSB is plugged in there.  Under this configuration, no joy with the KX3 Utility recognizing the COM port.

Configuration 2: My laptop is connected to the KX3 directly via USB port.  Under this configuration, no joy with the KX3 Utility recognizing the COM port.

Configuration 3: My laptop is connected to the KX3 directly via USB port.  Under COM port settings for the KX3USB connected port,  I changed the latency timer to 8 ms from 16 ms.  Under this configuration, the KX3 Utility recognizes the COM port every time.

Returning to configuration one with the lower latency timer setting does not allow the KX3 utility to see the com port, so no joy there.

BUT ? it?s a weird BUT ? If I connect the KXUSB directly to the laptop, open the utility and connect, disconnect the KX3USB from the laptop and connect it to the hub built in to the PK-232sc+, it works as long as I don?t exit the KX3 utility software.  I can even close the serial port in the software, BUT as long as I don?t exit the software, I can reopen the serial port and it works fine.  I can close the port and use other software that needs the KXUSB as long as I don?t exit the KX3 utility program (just leave it minimized) it works when I need it.

On the FTDI site there is a removal tool. Use it to wipe away com port drivers. Then re-install the FTDI drivers for your KUSB or KXUSB cable. 

Good luck!

Message-ID: <5CB3F03D.6451.13E3EB30@Gary.ka1j.com>


A follow-up;

While I still would like to buy an excess 
KAT3A for my K3 & if you have one, please 
contact me off-list. It turns out my KAT3A 
is now working perfectly at this time

Before I packed it up to send back for 
repair I looked at the socket and noticed 
they were not gold pins, only the male 
pins on the main board are gold. I doubt 
there would be corrosion so soon but 
what's to lose?

I dripped some Deoxit 100 in and let it 
set a few minutes, then squirted regular 
15% deoxit with its 85% lube, cleaned and 
reinstalled it. The KAT3A is now working 
perfectly on 160 again and as before, all 
the other bands are also working.

I emailed Elecraft to let them know I 
don't need the RMA and won't be sending it 
in. Glad they were there and willing had I 
needed to get it repaired.

73 all,

Gary

No. There were the usual show special deals and the KPA1500 was 
emphasized. The whole conference, including the vendor area, was 
fairly low key, with nothing new and earth shattering.

Subject: [Elecraft] [K1] TX part sick
Message-ID: <1555314267968-0.post@n2.nabble.com>

Hi all,

I am trying to repair the son's K1 where the TX seems to be sick. (receiver
sounds hot and quite nice on both bands 40/20m)

I found several C0G caps around the cores on the module board burned as same
as K1 relay so I replaced them all after long time searching them on the
market (EU). 

Now I am trying to check step by step according to manual the RF board (RF
2000 Rev.D) and I found that original builder (we did not built it) wound 5
turns of secondary T3 (green wire) instead of 4 described in manual. 

Should I remove the turn from T3 or is it possible to adjust the TX even
with that mistake?
I would like to avoid another burns...

Many thanks,

Petr,

The number of turns on T4 is not likely to make much of a difference, 
but I recommend correcting it just the same.

However, it is an indicator that there may be other toroids in that K1 
with an extra turn on them, so check all of them.

As for the transmit problem, it is only a guess for what may be wrong - 
the best answer if "anything" in the TX chain.

The best way to approach that problem is to turn to the back of the 
manual and do the Transmit Signal Tracing to determine which stage is 
failing.

It sounds like that K1 may have experience a lightning event (the burned 
capacitors are an indicator of that), so you may have multiple failures. 
  Work them one at a time.  Correct each one in turn and re-test after 
each correction.

73,
Don W3FPR

Dear OMs and YLs,
     I am going to help a friend get onto FT8.   He has a new Tigertronics
SignaLink, with the header for the K3 and appropriate cables for the K3.
This however does not in and of itself provide the ability to shift band or
frequency in the case of Fox Hound mode.

    Is it correct to say that a cable from the K3 RS232 port possibly via
the P3 to the PC is all that is required to gain this frequency shifting
capability.   The software being used other than what comes with the
SignaLink is standard WSJTX Version 2.? from K1JT's stable.

    I use FT8 some here but have a MicroKeyer II.   This is my first time
using a SignaLink.     Your guidance is appreciated.    Thank you in
advance.

Dear OMs and YLs,
      I looked up the KPA 1500 the other day on my phone and though I saw it
was CE approved.   Since then, I can not find this CE statement.    Does the
KPA 1500 finally have CE approval so that it can now be purchased into the
EU?     I have been waiting for this news for some time as I plan to buy.

             73 Doug EI2CN

PS For those outside the EU, CE approval is somewhat akin to UL approval.
A product can not be sold in the EU without this safety approval.

Don,

many thanks for hints.

I will re-check all cores on RF board as same as on band module...
We got this K1 in "repair needs" state from friend and the receiver sounds
nice at the moment.
So I would like to finish the repairing of TX path which burned to builder
probably during alignment.

I will let you know... at this moment I checked on RF board that T4 is
wounded ok (not nice but correct)
but T3 has more turns on secondary winding side. I will check all others to
be sure there is no more mistakes. I do not know if the final transistor
survived the last action > but we will see.

MNI TNX, 73 Petr

Doug,

The SignaLink has both a soundcard and a USB to Serial port adapter.  Be 
certain that the proper COM port and soundcard are selected in the data 
mode application.  The K3 RS232 menu parameter should be set to 38400 
and that same rate available in the COM port and the software application.

73,
Don W3FPR

Ray...
I did not realize that!? I did RTFM - I promise.? I guessed I missed that one. It has worked under the 1st configuration ever since I bought the KX3.? One day it changed - I was blaming a Windows update.


My K3s is connected to a USB hub external to my desktop PC and works OK - Of course, the K3s is a USB device.


Mystery solved!!

Hi Hank:


It's always been the case when using the Elecraft Utility, that you need to connect the rig directly to your computer, using the Elecraft cable.... with no other devices in line. ?That's why you succeeded with case 3.

Okay?some weirdness, but I can get the software to work.? Here is what I have done (some help from you guys, some help from the IT guys where I work, and the internet).? It's a little complex?

Configuration 1: My laptop is connected via USB to a PK-232SC+ which has a 2 port USB hub built in - my KXUSB is plugged in there.? Under this configuration, no joy with the KX3 Utility recognizing the COM port.

Configuration 2: My laptop is connected to the KX3 directly via USB port.? Under this configuration, no joy with the KX3 Utility recognizing the COM port.

Configuration 3: My laptop is connected to the KX3 directly via USB port.? Under COM port settings for the KX3USB connected port,? I changed the latency timer to 8 ms from 16 ms.? Under this configuration, the KX3 Utility recognizes the COM port every time.

Returning to configuration one with the lower latency timer setting does not allow the KX3 utility to see the com port, so no joy there.

BUT - it's a weird BUT - If I connect the KXUSB directly to the laptop, open the utility and connect, disconnect the KX3USB from the laptop and connect it to the hub built in to the PK-232sc+, it works as long as I don't exit the KX3 utility software.? I can even close the serial port in the software, BUT as long as I don't exit the software, I can reopen the serial port and it works fine.? I can close the port and use other software that needs the KXUSB as long as I don't exit the KX3 utility program (just leave it minimized) it works when I need it.

How crazy is that?? Any gurus figure that one out??

On the FTDI site there is a removal tool. Use it to wipe away com port drivers. Then re-install the FTDI drivers for your KUSB or KXUSB cable.

Good luck!

The? Signalink? provides only the audio path to / from the computer and 
radio.

You will need either the RS232 or USB interface between the radio and 
computer to handle the frequency control and PTT command.

Dave, I've been very successful using a RemoteRig configuration similar to
that described by Barry. Instead of a K3/0-Mini, I have a full K3 at the
control site where I can also operate locally when the suburban QRN
subsides. I use an external CW keyer at the control site and inject keying
into the RRC through a rear-panel connection, documented but non-obvious.
The local monitor in the RRC avoids the confusion caused by latency on the
remote K3's own sidetone. I use KPA500 Remote and KAT500 Remote instead of
the RC-1216 and I'm very happy with their UIs. They and other utilities I
use do require a server computer running at the radio site. I have a remote
power strip so I can power down individual devices. A remotely controlled
relay board controls various accessories. I use PstRotatorAz to control my
rotator and SteppIR beam.

The big and new difference between my config and Barry's is remote
panadapter. I was dissatisfied with a camera facing the P3 as it provided
no access to the P3 controls. But my logging program, N1MM Logger+, now has
a Spectrum Display window that I drive with an inexpensive Airspy HF+ SDR
at the radio site. It not only provides large-screen display and control of
spectrum and waterfall but also integrates with the band map in Logger and
the mouse for click-to-QSY functionality. Click on a callsign or signal
(with smart zero-beating), or click on a gap between signals, and you're
there! I can drive it either from the K3 I.F. Out signal or the K3 RX ANT
IN/OUT loop. Both work great and it has introduced a whole new dimension to
station control.

Internet connection is critical. You don't need high bandwidth but you do
need reliable packet delivery. At first, at the rural location of my
station, this was a problem - lots of snap, crackle, and pops in received
audio. But over time the ISP improved the cable plant and central office
equipment and now I can comfortably operate a contest with very little
evidence that I'm not actually sitting there.

The system integration is a challenging but fun project - don't get
discouraged by the many "moving parts." Get it going one piece at a time
and you'll be very satisfied with the accomplishment and the eventual
result of enjoying a quiet location for the radio while sitting where you
need to be sitting!

I don?t use a Signalink or any external device beyond the PC to operate FT8 on my K3s.

Maybe it's a K3s option (I just can?t remember if it was included or not) but the K3s USB I have enables rig control and also presents the K3s  internal sound card to my PC.

Just configure WSJT-X to use those two USB devices ?..no SIgnalink needed.

Paul,
     You are correct the K3s does have a built in sound card and it can 
obviate the need for a SignaLink interface. However, you can just use 
the radio's VOX vice computer controlled PTT. It works fine this way. 
This is what I do.

It's the I/O RJ45 connector on the back of the 1258, pin 4, that will 
key the remote radio, I use it with a Winkey3.? Pin 8 it ground, and 
while it is documented in a combination of schematic and pin-out 
diagram, it is, as Rick says, decidedly non-obvious.

Subject: [Elecraft] K3 SignaLink & FT8 Question
Message-ID: <201904151715.x3FHFJ84024973@mail40c28.carrierzone.com>

Paul (and Bob, etal):

I quite agree.  No signal link device is needed to do digital modes 
with either K3 or K3s.

I have a K3 (SN 4340) which has the RS232 control port.  I bought the 
USB/RS232 conversion cable from Elecraft.  I run JT65 just fine with 
two RS audio cables to my computer.

In later eme modifications to use MAP65 in dual-polarity diversity 
RX, I've added two LP-Pan which provide Rx audio and run both MAP65 
and another program that controls K3 frequency.  That mod required 
controlling the K3 from two comports so I made a RS232 splitter to 
separate RTS/DTV lines and RXD/TXD lines to separate 9-pin connectors 
(RS232). http://www.kl7uw.com/station%20layout.htm

But simple JT65 and FT8 don't need that complication.  Just run audio 
cables from the K3 transverter I/F to your computer and run the 
RS232/USB cable.

I do not have a K3s so may even be simpler with straight USB to USB connection.

I simply wonder why folks with the K3/K3s buy a signal link?  Not 
needed and merely adds confusion (unneeded expense).  I'm also told 
the signal link soundcard is inferior.

I don't run all the fancy HF logging/control sw which I think is also 
providing control issues for a lot of you wanting to do FT8 (with 
WSJT-X).  I can offer you no help with them (obvious there are 
experts on this list for that advice).

I don?t use a Signalink or any external device beyond the PC to 
operate FT8 on my K3s.

Maybe it's a K3s option (I just can?t remember if it was included or 
not) but the K3s USB I have enables rig control and also presents the 
K3s  internal sound card to my PC.

Just configure WSJT-X to use those two USB devices ?..no SIgnalink needed.

Hello Doug et all

The CE -marking is not "A REAL" approval, it's just A manufacturers 
claim of the product fullfilling the reqired standards. UL listing on 
it's behalf is an approval that's granted for the manufacturer after 
testing and inspection. The applicant must send all of the drawings, 
BOM, some required samples &c to UL. The UL inspector then regulary 
visits the manufacturer (an audit) to make sure that the approved 
product is as figured in the application of the approval... I worked as 
an UL representative years ago in FIMKO (Elecrical inspectorate of 
Finland) . So, don't worry about missing CE on the labels. In Finland 
some humorists call CE -marking as an abbreviation for "China Export" :-D.

If I connect the KXUSB directly to the laptop, open the utility and connect, disconnect the KX3USB from the laptop and connect it to the hub built in to the PK-232sc+, it works as long as I don?t exit the KX3 utility software.  I can even close the serial port in the software, BUT as long as I don?t exit the software, I can reopen the serial port and it works fine.  I can close the port and use other software that needs the KXUSB as long as I don?t exit the KX3 utility program (just leave it minimized) it works when I need it.

No interest shown here but I have been asked for more information off list.   Since the work is done I'll share it here.

The attached will give you some idea of how PA dissipation and PA efficiency change with output power and loading.   These plots are from a test I ran last year, long before the KPA500 Monitor page was added to my Arduino interface.  The introductory para of the incomplete report is quoted below:


"Summary

A semi-automated test was run for various frequencies and PA load conditions.  Spectrum lab was used to generate a 1,000 Hz tone with a sawtooth amplitude profile.  This tone was used to modulate the TS-590S exciter. An Arduino based data logger recorded serial data from the KPA500 and an LP-100A.  These data were processed in Excel by using a pre-defined template.  The LP-100A provides SWR, Z, and phase angle.  X and R were computed from Z and phase angle."

Are you using a USB to serial adapter?  If so, have you downloaded and 
installed the latest drivers for that adapter (if the Elecraft KUSB the 
drivers are from FTDI).  Reboot the computer after installation.

Use a USB port on the computer, not on a hub.

Out of curiosity. did Flex Radio Systems tout their new SmartSDR v3,0.19 featuring ?multiFlex? that allows two operators to share one Flex-6xxx series transceiver (or one operator use two devices such as a laptop with SmartSDR and a Maestro connected to the same transceiver at the same time)?  Given the focus on DX and contesting at Visalia, I?m wondering what the crowd reaction might have been to this newly released capability?  

I suspect that while this is a technical achievement, non-contest users are being challenged to determine how exactly multiFLEX works and what advantages it brings to their operating experience.  However, there appears to be significant benefits to multi operator contest stations as well as single operator two radio (SO2R) setups, reducing the number of transceivers and associated control boxes/cabling while allowing both two operations using the same transceiver to share the same antenna. 

I also suspect that what is driving Flex?s focus on the needs of contest operations is that contest stations spend ?real money? on equipment and software to enhance their competitive advantage. It?ll be interesting to see whether the evolution of technology by Flex using SDR will translate to tangible benefits for the "rest of us? as well as whether other equipment manufacturers respond to these technical enhancements.

"Use a USB port on the computer, not on a hub."

Why is this restriction imposed on the K3 utility?  The KAT500 and KPA500 utilities work fine through my 10 port hub.

I can, and almost always do, use the K3/P3/KX3 utilities through 
a hub to my Elecraft USB <--> RS232 cable or K3 upgraded 
internal equivalent from my Mac. The connection between the two 
USB <--> RS232 connections persist over shutting down and moving

What is going on with Windows USB support?

You certainly don't need a SignaLink or any computer sound card 
with an upgraded K3 or a K3S.

The early SignaLinks has a number of problems. I saw a web site 
that gave directions for fixing them, opened up my, by now quite 
old, SignaLink and found that every one of the modifications was 
included in my version of the SignaLink.

BTW, I am using a $5 from Amazon sound dongle with a homebrew 
audio cable (with a pad to reduce the Mic input to the dongle) 
with my KX3. It is much smaller and therefore easier to 
transport, but works well.

I didn't spend any time at the Flex booth, although their signas 
touted SmartSDR Version 3, so I expect they were also talking 
about multiFlex.

While there may not be a lot of use for multiFlex in the normal 
DX chaser, perhaps except for those stations that really don't 
want US responses so transmit in the US phone band but listen in 
the US CW band, there are some interesting uses for DXpeditions.

AA7JV was interested in running both CW and FT8 on 160M with one 
amplifier and transmit antenna. (He said setting up two stations 
was too much work, and you needed to be running both modes on 
those "magic nights" when 160 was open.)

He described an approach using a Flex in his talk at the Topband 
dinner and in his ""The RIB: Radio In a Box for DXpeditions" session.

The idea of RIB is to put the box in the rare DX with a 
generator and antenna, and operate it from the boat off shore 
via UHF based internet, just visiting the DX to set up, service 
the generator, and tear down.

So, speaking of the K4 . . . 

When Eric asked a few weeks ago what we might like to have if there were to be a next generation transceiver, near the top of my list was adding whatever it would take to make it unnecessary to connect the transceiver to an outboard computer -- so far as reasonably possible -- ever, for anything.  Eric eventually closed that thread and I don't mean to reopen the wider question.  But would something along those lines ease the kinds of problems we've been reading about here lately?

and a RS232 port on the PC and a cable from the P3 XCVR port to the RJ45 
connector on the K3s.

Any help would be appreciated.

I use a powered hub with my K3S, no problems. I  haven't tried it with an unpowered one.
Granted, maybe the KX3 is different...

Ray...
I did not realize that!? I did RTFM - I promise.? I guessed I missed that one. It has worked under the 1st configuration ever since I bought the KX3.? One day it changed - I was blaming a Windows update.


My K3s is connected to a USB hub external to my desktop PC and works OK - Of course, the K3s is a USB device.


Mystery solved!!

Hi Hank:


It's always been the case when using the Elecraft Utility, that you need to connect the rig directly to your computer, using the Elecraft cable.... with no other devices in line. ?That's why you succeeded with case 3.

Okay?some weirdness, but I can get the software to work.? Here is what I have done (some help from you guys, some help from the IT guys where I work, and the internet).? It's a little complex?

Configuration 1: My laptop is connected via USB to a PK-232SC+ which has a 2 port USB hub built in - my KXUSB is plugged in there.? Under this configuration, no joy with the KX3 Utility recognizing the COM port.

Configuration 2: My laptop is connected to the KX3 directly via USB port.? Under this configuration, no joy with the KX3 Utility recognizing the COM port.

Configuration 3: My laptop is connected to the KX3 directly via USB port.? Under COM port settings for the KX3USB connected port,? I changed the latency timer to 8 ms from 16 ms.? Under this configuration, the KX3 Utility recognizes the COM port every time.

Returning to configuration one with the lower latency timer setting does not allow the KX3 utility to see the com port, so no joy there.

BUT - it's a weird BUT - If I connect the KXUSB directly to the laptop, open the utility and connect, disconnect the KX3USB from the laptop and connect it to the hub built in to the PK-232sc+, it works as long as I don't exit the KX3 utility software.? I can even close the serial port in the software, BUT as long as I don't exit the software, I can reopen the serial port and it works fine.? I can close the port and use other software that needs the KXUSB as long as I don't exit the KX3 utility program (just leave it minimized) it works when I need it.

How crazy is that?? Any gurus figure that one out??

On the FTDI site there is a removal tool. Use it to wipe away com port drivers. Then re-install the FTDI drivers for your KUSB or KXUSB cable.

Good luck!

get rid of junk files and also clean the Registry. That's two different

Type    Device Manager in your search 
window. When it opens look for "Ports"

write down your existing port numbers.

Pull your USB.

The number that leaves is your necessary 
port number.

re-attach the USB and now in the utility, 
go to that port number with the proper 
baud (38K, 36K, something like that) and 
you should reconnect

An inexpensive USB sound card (look for one with line in) say about $15(US)
and a couple of audio cables is all you need. Set your levels (4 bars with
5th flashing on transmit, best decode on receive) and away you go. I am not
familiar with FreeDV, if it has the ability to do PTT over com port you can
key with that, otherwise you can set up VOX. KX3 does not do FSK, you have
to use AFSK. Not a big deal, just keep an eye on the transmit level.

Bob, May I ask you a further question, please?    Do I need any additional
software for the interface from the K3 serial port to the PC using either
RS232 or USB and an adaptor?    I understand that the SignaLink may not
itself be required but am going to proceed with it anyway.   I would like to
make sure that WSJTX can shift the frequency and band for FT8.   Thank you
for your help.

The? Signalink? provides only the audio path to / from the computer and

You will need either the RS232 or USB interface between the radio and

Hi folks,

can you split the threads?

It has nothing to do with originally launched Hamradio/K1 TX part repairing
thread please.

Thanks,

Petr, I have no idea how the threads are combined.   I initiated this
question without any reference to the K1 and used the title above which does
not mention the K1.    I am trying to resolve a problem not cause one.   My
interest it that when visiting a friend in USA that I can get him up and
running with his K3 and his new SignaLink on FT8.    My specific concern is
with WSJTX controlling the frequency.   Sorry for any trouble cause your
good self.

Don,

I checked other parts in TX section and it seems to be ok (refer to manual
2000 Rev. D). Just removed the 5th turn on secondary winding of T3. 

Is there something else strange or danger which I should check in order to
avoid smoke during the test or even blowing the final please?

Many thanks mate,

Petr

Petr.

Turn that manual to Appendix E near the back.  And on page 6 of that 
Appendix, you will find Transmitter Signal Tracing.
Set up the K1 as instructed there, and no damage will be done.

Then make the measurements in the order listed.  You will need an RF 
probe.  If you are using an oscilloscope (with a 10X probe), multiply 
the expected values by 2.8 to obtain the expected peak to peak RF 
voltage measurements.

At the FIRST measurement that is significantly less than the expected 
value (expect as much as a 10% variation before saying it is 
significant) you have reached the output of the failing stage.
Correct that stage and move onward to the next failure point.

That is the procedure required to determine why it is not working.

If the final is blown, replace it with the K1PAKIT from Elecraft.

73,
Don W3FPR

Sorry for the delay answering, we're on holiday and the Iphoney thing is not easy with my fingers.  
Essentially, add a video capture box to the the vga output from the P3 and send that with the radio data.  Don't ask me any more, I just don't know.  The main thing is you don't need a camera to look at the P3 screen which would lose resolution and seems very clunky to me.  Looking forward to doing this in the next month or 2.  Eric gave me his card to call him when I'm ready.  He was demonstrating the system at the show via hotel WiFi which kept dropping.

Doug,
     To try and get you an answer, I offer the following. The SignaLink 
requires NO software for itself. It will show up as a USB CODEC. It is 
this that you need to tell WSJTX that you want to use. That solves the 
audio issue. Frequency will be controlled by WSJTX if you tell it what 
radio you are using, port it is on, and port data rate and format. The 
latter is usually 38400 and 8N1 and the port number available from the 
computer's device manager. To transmit, use the VOX on the radio and 
nothing else is required except to set the levels and make sure you are 
in DATA A mode. Have fun.

73,
Barry

Been building/home brewing  since I was 11.

K2 sn40 was the most fun radio building experience of my life, with K1, KX1 
,KX2, KX3 and others being the frosting on the cake.

K2 still monitors 6 meters with the transverter , as the  K3S  is in the 
main position now, where Wayne's Sierra was way back when now.

Thanks for making it fun guys.

This is close. As others have stated, two adapters are required. One is the Signalink (or other audio interface). The second is a serial adapter, preferably based on an FTDI chip. I believe it is the second you are really asking about. The serial adapter provides the actual control communications between the computer and the K3. It is the same interface you would have used for updating K3 firmware or otherwise controlling the K3 from the computer.

The Signalink should do a good job providing the sound interface needed for FT8 with the K3. There are other less expensive solutions (and several that cost more as well), but since you already have the Signalink, use it!

WSJTX is relatively easy to get going, but you will want to read the manual to be able to understand and set the various details in the program. Just select the audio interface and the serial port in the WSJTX settings dialog and things should start working quickly. After you start playing, you will have more questions.

73!

That solves the audio issue. Frequency will be controlled by WSJTX if you tell it what radio you are using, port it is on, and port data rate and format. The latter is usually 38400 and 8N1 and the port number available from the computer's device manager. To transmit, use the VOX on the radio and nothing else is required except to set the levels and make sure you are in DATA A mode. Have fun.

Subject: [Elecraft] Elecraft's philosophy of community input on product
	design
Message-ID: <ABD8E072-7F08-4ACE-AE3A-38B4F46C0503@elecraft.com>

It has often been stated, by both Elecraft and our customers, that we leverage user input as we flesh out new products. In this article I'll clarify our development model, hopefully elevating it above hearsay. It's intentional and methodical. We like to think it's one of the things that makes Elecraft unique among well-known amateur radio brands.

* * *

The design of commercial gear is subject to many constraints. It has to meet user expectations, earn type acceptance, do well in performance benchmarks, and yet be fairly priced. To varying degrees it must also satisfy a universal requirement for communications gear: it should be usable during emergencies to support local or regional traffic. (For some of us, knowing we might be called upon as the last resort in difficult times motivates us to keep our equipment and skills fresh.)

Most use of our gear is by hobbyists, so an additional set of requirements comes into play. For example, a radio has to be enjoyable to operate. If it's a kit, it must be rewarding and educational to build.

We take this two steps further. 

First, we believe that our customers -- the real experts when it comes to using ham gear -- are a rich source of creative and technical input. Second, we recognize that since this is a hobby, the road is just as important as the destination. In other words, we want to share the *process* of product design with our customers, not just plant a stake in the ground and say "this is what we've done; take it or leave it."

To this end, at the onset of a new product cycle we imagine the hardware and firmware as an elastic canvas upon which we and our customers can sketch and refine ideas. This means products must be endowed with a great degree of modularity; we have to leave spaces that can be filled in the future, firing the imagination of users. Here's a musical analogy: If you've ever listened to jazz trumpeter Miles Davis play, you'll notice some gaps between his phrases. These allow listeners to engage with his music, completing their part of the conversation. The result? You work a bit harder at it, but come away more satisfied. (Don't get me started on the Key of Morse.)

What this means in practice is that we take continuous customer input, weight it, adjust firmware implementation priority, and revise or extend hardware over time. Let me give you two examples of how this has played out.

K2

The K2 was the test case for our "canvas" development model. To ensure flexibility, we designed intermodule communications around a 1-wire bus -- the auxBus -- which we routed to every option connector in the radio. These connectors were strategically distributed to nodes where they could pick up supply voltages, control, and RF or audio paths. The idea was that each module would have its own small MCU, hanging on the auxBus, where it could exchange information with the main MCU.

We then started shipping the K2 to early adopters, soliciting their input on what they'd like to see next. I can't claim that this process was entirely democratic, and in truth it was messy at times. But the upshot was that we quickly followed with new K2 options and firmware features in an order that gave users a vote. When 60 meters came on the scene, we added a module for that as well.

Here's where the auxBus comes in: On power-up, each option module checks in with the main MCU, reporting its status. But the MCU needn't know every detail of how modules function. For example, when you go into the menu entry for the K2's ATU (KAT2), the text for the various settings is supplied by the KAT2's own MCU, over the auxBus. If you update the ATU module to one that has different settings, the main MCU doesn't have to be updated -- just the KAT2 itself. The main MCU thus functions as a "server" for semantic information supplied by each of the option modules.

The K2 is also an exemplar of hardware flexibility, embodied in something we called the 2D fastener. This is a short length of 1/4" aluminum bar with three tapped 4-40 holes that permits attachment of PC boards, sheet metal, and hardware. Over the years we and our customers have taken advantage of 2D fasteners to upgrade or enhance products. Our seafaring customers helped us migrate to all stainless-steel hardware at some point, facilitated by 2D fasteners as generic attachment points.

Shortly after we thought we'd fully populated the K2 with options, we were contacted by Lyle Johnson, KK7P. Lyle had reverse-engineered the auxBus node associated with our KAF2 analog audio filter module, where he inserted his own: the KDSP2, a DSP-based audio filter complete with noise reduction. This is an extreme case of tapping community creativity. In addition to adding the KDSP2 to our product line, we added Lyle to our engineering staff.

One final note about the K2 and extensibility. Once we had accumulated a number of useful upgrades, we created an "A" to "B" conversion kit. This was the genesis of our promise to provide an upgrade path for every owner of our transceivers so they can remain current. 

K3

The K3, with its larger MCU and plenty of interior space, has benefitted from many suggestions by its user base over the 10 years since initial release. We phased in a high-performance sub receiver, 2 meter transverter, enhanced ATU, DVR, SWL band-pass filter array, reference lock module, USB port for control/audio, and most significantly, an entirely new synthesizer design. As the phrase "competition-grade" evolved, the K3 continued to set the standard.

Accessories have been added to the K-Line based on customer needs as well -- the P3 panadapter, KPA500 amp, KAT500 ATU, SP4 speaker, and K-Pod remote controller. All of these new modules and accessories were accompanied by hundreds of free firmware upgrades. 

Like the K2, the K3 underwent one major face-lift, in the form of the K3S. In keeping with our model, we offered just about everything but the "K3S" front panel bezel to those who wanted the latest in Elecraft tech.

* * *

Our first two decades have been a time of challenge, opportunity, and satisfaction for our team. Reflecting on this time, we need to thank our customers not just for their creativity and enthusiasm, but also for their patience. We've traveled the road together, bumps, potholes and all, and I hope you've all enjoyed the ride as much as we have.

It goes without saying that our future products will continue to reflect our philosophy of community involvement and "hands-on" design. 

Here at Elecraft headquarters, we're already raising a toast to the next decade.

Wayne, N6KR

I believe that putting WIN10 hardware in the radio will be a benefit to the OEM.  It will make the radio become obsolete faster and allow more sales for upgrades.

Maestro, SunSDR, and Anan MK II radios all have Win10 PCs embedded.  Those radios? embedded PCs are all obsolete already.  
Consider how much pain it is to deal with Windows 10 updates.  I am sure the radio OEMs are paranoid, or at least I would be were I one of them.  When you have a widely deployed product that suddenly stops working because of an update, the pain is intense and expensive to cure.   

How about an Intel NUC instead of a PC ?   They were used on Heard and Ducie rather than using laptops.   Even NUCs do not support IPA 4K monitors, yet.

It's already possible to use a K3 without a computer.  I've done that in the
middle of a contest when I had to re-boot my computer.  I logged on paper
until I had access to the log when I added those contacts.

Regarding computer-related problems, having provided on-line and telephone
tech support for Gateway, the majority of troubles with which I helped were
user-induced.  I liken the issue to when I had responsibility for a small
phone system--lack of knowledge on using that "tool."  I assert we need to
have sufficient knowledge to operate and maintain our computers, just like
our radios.  Sometimes we need to seek help from others, often found on this
list.

I also assert too many ops aren't conversant with their equipment and much
less with their equipment manuals.  Of course, we all do dumb things and I
am near the top of that list.  Still, I update my PDF manuals and make use
of them.  For Windows, Google is your friend.  It is more useful than trying
to find help on Microsoft's web site, in my experience.

I use electronic loggers for many reasons.  Except for the fine products at
QRPWorks, I use a computer and the appropriate logger.  I am a keyboard wiz
and can type much faster than I can print.  BTW, I have often used the K3
Utility with a USB hub.  But, not all USB hubs are created equal and I
always bypass a hub when troubleshooting connectivity issues.

I would rather have the K4 firmware space used for features rather than
replacing functions best done on a computer or other external device.  It is
2019 and computers belong in our shacks, IMHO.  On SOTA peaks, that may be a
different story.  Still, I prefer a non-radio solution for logging, like a
notebook computer, than having a logger in my radio.  Save that battery for
operating!  Just my humble (or not) opinion.

BTW, I enjoyed several conversations with Elecraft personnel at the IDXC
this weekend and with Bill, AE6JV.  I also noticed WA6HHQ on APRS.  It was
an excellent convention once again and I hope the plans to move it to the
Wyndham next year revert back to the Visalia Convention Center with its
larger facilities.

73, Bill, K8TE

So, speaking of the K4 . . . 

When Eric asked a few weeks ago what we might like to have if there were to
be a next generation transceiver, near the top of my list was adding
whatever it would take to make it unnecessary to connect the transceiver to
an outboard computer -- so far as reasonably possible -- ever, for anything. 
Eric eventually closed that thread and I don't mean to reopen the wider
question.  But would something along those lines ease the kinds of problems
we've been reading about here lately?

Ted, KN1CBR

PLEASE!  No operating system embedded in the radio.  Almost like ice cream, there is more than one flavor. 

As to Windows 10 updates, configure for automatic, let it do its thing, and don't mess with the parameters.  It is so easy and reliable.  Don't make it complicated by trying to run it yourself. 

You also need to maintain a "clean" computer with regular Cache and Registry cleaning.  Leftover and fragments may over ride new updates.  Also Virus and Malware issues may interfere with correct operation.

Yes, you HAVE succeeded using a difficult and unique business model that 
accommodates and fulfills the experimental and developmental aspects of 
ham radio.? Think about it ... to buy an Elecraft radio, especially in 
the very early days, is to buy an essentially unfinished 
work-in-progress undergoing constant development,? against the promise 
that bugs, foibles and peccadilloes will be cured with future firmware, 
and occasionally hardware, updates.?? This realizes a major legal 
purpose of ham radio:? the advancement of radio science.?? Elecraft 
owners are more than mere consumers;? they are an integral part of the 
process.?? While this is not my style,? it appeals to a large number of 
operators willing to experiment and participate in product development, 
serving as so many ersatz field test sites. Had performance lagged, or 
had Elecraft failed to deliver promised features and improved 
performance, the company would have been relegated to ham radio history 
long ago. Personal accountability and accessibility while looking? the 
customer directly in the eye is a significant factor in its success. 
Selling both a process and a product is a bold, risky course.? 
Fortunately, Elecraft has delivered the goods well enough, and often 
enough, to earn its place in the race.

That is just MY take, of course ... your mileage may vary. K8JHR

My guess would be that you don't have it connected to the K3 serial port
correctly. If it isn't getting frequency information, it has to stay in
scrolling mode.

I commented earlier regarding Windows 10.?? If you have ever had a 
program crash or the computer lock up, then you most likely will have 
command line fragments on your computer.? Some of these may not cause 
issues but some may.??? To be safe, use a software application to clean 
and clear the Cache and clean the Registry. There are several good ones 
that are FREE.?? {The best kind for hams}

I think that's the way it's supposed to work in fixed-tune mode. The 
display stays at the same frequency and the VFO moves across the display 
as it is tuned.

By contrast, in tracking mode the VFO always stays at the center of the 
screen and the frequency of the display changes to track the VFO as it 
is tuned.

There was a time when I would have agreed with you.  In this day and age,
Win 10 is complicated beyond this user's capability to follow a set of
mutually exclusive text menus and settings with more on/off switches than a
bunch of Altair 8800's stacked to the ceiling and cascaded additionally.
Who outside of specialists can understand the implications of so many
settings?  

There was also a time when Googling a resolution of a Windows matter was
fairly easily had.  Anymore one can spend hours reading what doesn't apply
to find what does apply.

The overhead of maintaining my system has grown quite a bit.

PC ---> Personal Computer..?  No longer.  It may be 'personal' in that one
owns the hardware...arguably the software.  The resources required to keep
up with it get a bit beyond 'personal.'

Hi Wayne,

OK, I'll be the one to ask...  Is this Elecraft's way of saying a K4 is 
forthcoming?  ;)

Dave,

The answer (as always) is Yes, Elecraft is always working on something new.

The real question is "when", and that will be unknown until it is announced.

Whether it will be called "K4" or something else remains to be seen at 
announcement time.

73,
Don W3FPR

Subject: [Elecraft] FT8 distorted audio, won't decode
Message-ID: <00f201d4f4b8$9ffe7400$dffb5c00$@w2irt.net>

Hi all,
Whenever I bring up WSJT-X and the radio goes into DATA mode (Data A), the
audio through the speaker is extremely distorted and there is no decode at
all. Soundcard RX Levels are about 30 dB. If I switch the radio into USB I
can decode just fine, but not using the DATA mode. I haven't changed
anything in the radio or software since the last time I used FT8, about a
month ago. I've hardly even had the radio powered up for more than a couple
of hours in the last month. Any idea what could have gone wrong, or where I
can go to fix it? I'm sincerely hoping this is a software problem and that I
didn't somehow harm the receiver.

I'm not using the Noise Blanker or Noise Reduction, AGC is set to either
Fast or Slow, I'm on the main antenna, signals are very strong, and I've
tried with and without the attenuator. Nothing shows up on WSJT's traces in
Data mode.

Hi Don, Petr and all,

I have a similar TX problem that I've been working on for a time. 
Reading your emails I realized
that I'm using a K1 manual Rev. J. 2015.

My K1 is from around 2000, Rev. D, and I'm now asking if the Rev. J of 
the manual is OK to use
as reference and for troubleshooting?

I have been searching for K1 Rev. D manual but can't find it.

Thanks!

Bert VE3NR

Message-ID: <06A2B856-341E-4204-9AD3-281D856A0CA4@yahoo.com>

Hi guys! I searched around a bit nothing conclusive so thought I?d ask.

I am needing a foot switch for my K3s which is also connected to my KPA500/KAT500 setup.

I purchased a Heil FS-3 however it has a 1/4? phono plug on it and the K3s has an RCA jack (like a dummy I did not look at the back of the radio before I bought it).

So, recommend an adapter or I can take this one back to HRO and get something else?

Recommendations?

What we call a ?foot switch? is a ?sustain pedal? in guitar speak (the real market).  The standard is a 1/4? plug.  Buy an adapter.

Hi Ken

Foot switches or hand switches are pretty simple devices.

All they do is 'ground' the center conductor of the PTT line.  When you
ground it, the radio goes into TX.

If the Heil unit you purchased has the wrong connector on it, you can just
purchase an adapter from a company like Mono Price (
https://www.monoprice.com/product?p_id=7242 $0.79) or cut off the connector
it came with and solder on the RCA connector you need.

Yes, exactly.

My Boss FS-5U has performed flawlessly for 15+ years including a few 
Field Day trips to the mud. Very durable. The sides are keyed so you can 
lock multiple together.

Michael,
This adapter should work.  1/4" mono female to rca male adapter

https://www.amazon.com/CGTime-6-35mm-Adapter-Female-Converterr/dp/B07HD3Z5R1?SubscriptionId=AKIAILSHYYTFIVPWUY6Q&tag=duckduckgo-d-20&linkCode=xm2&camp=2025&creative=165953&creativeASIN=B07HD3Z5R1

Sure it's a pack of 5 but if you look around I'm betting you can find it 
in solo or twin packs.

Or if you really want a Heil foot switch then the FS-2 looks like it 
would work.  Or as some one else mentioned, bust out the soldering iron.

Been trying to configure SDR Uno with RSP2 as a spectrum scope. (Using IF output to RSP) But not much luck.Right now, when I turn on SDR Uno, with the K3 already in CW mode, the SDR keys the rig for a moment, then stops.The "ERR KEY" message shows up on the screen.Can't get the message to clear, and can't send CW, so have to pwr down the rig, to get the error message to clearand to be able to operate the K3 agn.Anyone else with SDR Uno/RSP2 have this problem?Any suggestions appreciated.TIA,Bob K4RLC

In 2015 I bought one of these:
https://www.amazon.com/Linemaster-Clipper-Switch-Electrical-Momentary/dp/B00
2P55Y36/ref=sr_1_18
This is an Industrial grade, very high quality footswitch. You can wire it
NC or NO. Takes 5 minutes to set up. You'll never need another switch after
this. 

There were versions of these pedals installed in film projection booths I
worked in throughout my career, to do changeovers between machines; they
were installed in the 40s and 50s and were still going strong when I left
the industry. They are indestructible and worth every penny of their $30
price.

What we call a "foot switch" is a "sustain pedal" in guitar speak (the real
market).  The standard is a 1/4" plug.  Buy an adapter.

Hi guys! I searched around a bit nothing conclusive so thought I'd ask.

I am needing a foot switch for my K3s which is also connected to my
KPA500/KAT500 setup.

I purchased a Heil FS-3 however it has a 1/4" phono plug on it and the K3s
has an RCA jack (like a dummy I did not look at the back of the radio before
I bought it).

So, recommend an adapter or I can take this one back to HRO and get
something else?

Recommendations?

Gee folks, we can build our own transmitters and amplifiers and 
experiment with them on the air.

Why is it so hard to get an RCA plug, cut off the 1/4 inch phone plug 
and solder on an RCA plug?
Much easier than searching for an adapter.

The troubleshooting section is about the same - no problem.

Do not rely on the board Rev level to be the same as the manual level. 
There is no Rev J K1 board.

No Kidding... Exactly.  I have the dual radio/amp switch and I managed.  :-)  However, buying and adapter is often a great option when money is good and time isn't.

You know, I would be tempted to get a 1/4? female cord-mount jack and a cable with an RCA plug on it, shorten the end of the cable without the RCA plug (just to make a short adapter), slip on the connector housing, then solder the remaining cable to the 1/4? jack. That gives an adapter with some strain relief, thus reducing the lever-arm strain of a single-body adapter on the radio?s RCA jack, and would allow me not to have to modify the foot switch cable.

Michael, if you need help with that, let me know and we will see what we can do.

All this talk about onboard computers (or not) and operating systems in the K4 has me thinking.
My K3 is serial no. 0007. I have had it since the beginning, and with a few simple upgrades, it is almost as capable as a new K3S. But the computers I had back then are long gone.
What I would like to have in the K4 is a backplane architecture. The entire radio except for a control head would be located on plugin boards that could be swapped out easily for testing, customizing, or upgrading. The ENTIRE radio. The K3 goes in this direction, but not far enough.
One of the options would be an onboard computer. You could use the rig without it or with an external computer if you wish. Maybe it would come with some version of Linux, but you could put another version of Linux or Windows on it if you wanted. You could upgrade it easily when it became obsolete.
Yes, this would cost more. But with the savings available from modern automated surface mount construction, maybe it?s possible.

The last time this was discussed, there were many satisfied users of the Linemaster Treadlite II foot switch. Here is one with an un-connectored cord. As you check out the reviews on the variations of the Treadlite II, you?ll find the ?yeah, had one on a drill press for twenty years? reviews.

Tonight I attended a presentation by Ned Stearns AA7A on the Dxpedition version of FT8, and his extensive architectural design contributions to the Baker Island operation as well as his input to Joe Taylor's work on the protocol. While most of us don't need anything like the Baker station setup, the technical issues may nevertheless influence the direction and needs of the overall amateur gear market. With Elecraft's emphasis on supporting Dxpeditions I am sure that they look at such issues when considering new features for the K4 etc. Just a few points from the presentation that stuck in my mind: 
* The radio transmit frequency must be controlled by both the logger and the JT software, which work together but are separate. I have no personal experience with FT8, but I understand that (either with the current version or very soon) the DX hunter's transmit frequency will be dictated automatically on the fly by the DX starion, within a segment of the overall FT8 frequency window, such that the DX can overlap several FT8 qso's in time. This necessitates working around the basic "single sender" RS-232 signalling scheme. Ways to do this were recently discussed here, and need not be repeated. My point: Elecraft might consider an attempt to standardize a new communication scheme for station control, such as to simplify the whole setup. Wiring a station is already disturbimgly complicated where multiple radios are involved.
* The DX station would thus go beyond "SO2R" to something more like "SO4R". The FLEX approach already seems to have an edge in savings on mulit-radio hardware; a market-leading Elecraft architecture might optimize overall hardware cost when one operator is to use 2,3 or 4 virtual radios. Just hope it can be done so modularly that a small configuration is still affordable.
* With the current interest in FT8, there seems to be pressure for the hardware to have capability to process a frequency segment that is larger than an SSB bandwidth.

I didn't spend any time at the Flex booth, although their signas touted SmartSDR Version 3, so I expect they were also talking about multiFlex.

While there may not be a lot of use for multiFlex in the normal DX chaser, perhaps except for those stations that really don't want US responses so transmit in the US phone band but listen in the US CW band, there are some interesting uses for DXpeditions.

AA7JV was interested in running both CW and FT8 on 160M with one amplifier and transmit antenna. (He said setting up two stations was too much work, and you needed to be running both modes on those "magic nights" when 160 was open.)

He described an approach using a Flex in his talk at the Topband dinner and in his ""The RIB: Radio In a Box for DXpeditions" session.

The idea of RIB is to put the box in the rare DX with a generator and antenna, and operate it from the boat off shore via UHF based internet, just visiting the DX to set up, service the generator, and tear down.

I also enjoyed Ned's presentation.

There is however no need for new transceiver architectures to support FT8
DX mode.

The multi-transmission for FT8 Fox is created entirely through software by
combining
the baseband (audio) signal for each "transmitter" into a composite signal
fed to the
transceiver. Multi-reception is also purely a software affair.

Any modern radio, including the K3, supports this out of the box.

There is thus no need for multiple CAT interfaces.

Unless you want to run several bands simultaneously in one radio, of
course.
But that is no different from CW or any other mode.

PS For those outside the EU, CE approval is somewhat akin to UL approval.
A product can not be sold in the EU without this safety approval.

Don,

many thanks.

I am going to do it step by step accordingly during coming Easter holiday.
I will report then after...:)

Hi Bob,

I've been playing with the RSP1A at the IF of my K3 and HDSDR and SDR 
Uno as panadapter software. I also had Omnirig running for this. Never 
bumped into the kind of problem you describe. I can reproduce your 
problem though, by setting up omnirig with wrong RTS/DTR setting. One 
thing to observe is that you connect OmniRig to the K3 with RTS and DTR 
low. This will probably cure your problem.

HDSDR / SDR Uno and the RSP1A? not really gave me the results I want. My 
best and cheap panadapter is still the IF-Softrock plus my pc-onboard 
soundcard. Software: NAP3 and LP-BRIDGE. Wonderful pieces of software 
(THANK YOU GUYS). They do the trick for a beautiful panadapter (in 
collapsed mode) and flawless integration with the K3 and other software. 
The noise floor might not be as low as in the P3 of LP-pan, but it works 
for me as a panadapter.

That's why I was looking for someone who may have used the KX3 with 
FreeDV, maybe no one has yet...

Yes and the length of the 1/4" phone plug plus the length of the adapter 
to an RCA connector is something of serious length sticking out behind 
the radio.? Sure is a grand opportunity to get the radio RCA connector 
damaged.? Estimated total length of the albatross is about 3".??? Not on 
my radio!

I use a Heil FS-3. I just cut the 1/4 in plug off along with much of the 
surplus cable and fitted an RCA plug. Couldn't be easier.

What we call a ?foot switch? is a ?sustain pedal? in guitar speak (the real market).  The standard is a 1/4? plug.  Buy an adapter.

Hi guys! I searched around a bit nothing conclusive so thought I?d ask.

I am needing a foot switch for my K3s which is also connected to my KPA500/KAT500 setup.

I purchased a Heil FS-3 however it has a 1/4? phono plug on it and the K3s has an RCA jack (like a dummy I did not look at the back of the radio before I bought it).

So, recommend an adapter or I can take this one back to HRO and get something else?

Recommendations?

Those adapters will place a lot of torque on the back of the K3. A better idea is an adapter with connectors on each end of a wire.

Michael,
This adapter should work.  1/4" mono female to rca male adapter

https://www.amazon.com/CGTime-6-35mm-Adapter-Female-Converterr/dp/B07HD3Z5R1?SubscriptionId=AKIAILSHYYTFIVPWUY6Q&tag=duckduckgo-d-20&linkCode=xm2&camp=2025&creative=165953&creativeASIN=B07HD3Z5R1

Sure it's a pack of 5 but if you look around I'm betting you can find it
in solo or twin packs.

Or if you really want a Heil foot switch then the FS-2 looks like it
would work.  Or as some one else mentioned, bust out the soldering iron.

Is there an APP for this??? Or, let's make it as complicated and wordy 
as possible! I know, let's build a mountain from a mole hill!

Cut the offending plug off and solder a proper (for your needs) plug on! 
It could not be easier!

Agreed but I would really make sure that the switch is acceptable before
modifying it. I do not use a foot switch but I am aware that there are many
different ones available. Also if I recall the Heil foot switch will plug
into their adaptor if you are using the front mic jack.

Why is it so hard to get an RCA plug, cut off the 1/4 inch phone plug

Much easier than searching for an adapter.

I set up FreeDV once, but it was a while ago. It is exactly the same as setting up any digital mode for radio connections. The difference is that you also need to hook up a headset (or mic and speakers) for the operator. Get the radio side set up first using test tones.

Having become the proud father of a KPA1500, I am enjoying it a lot. I use a 
160M Full Wave Loop on Ant 1 and my Sommer log fed yagi on Ant 2.  I only 
have one 2KW HF Sensor for my P-3 and currently have it hooked up to Ant2. I 
would love to also have one hooked up to Ant 1, but the P3 has only ONE 
sensor input.  How do any of you get around this? My only thought is to use 
only one antenna port out of the KPA1500, to an antenna switch, but this 
negates the auto band switching of ports in the KPA.

looking for answer here.

thanks

20 plus years ago I slung some wire in a tree with a fishing pole at Yellow

Wyoming and the park.  The only call I got on my CQs was N6KR.

It has often been stated, by both Elecraft and our customers, that we 
leverage user input as we flesh out new products. In this article I'll 
clarify our development model, hopefully elevating it above hearsay. It's 
intentional and methodical. We like to think it's one of the things that

Here's what I use.? It allows switching up to four sensors to one P3:

https://smile.amazon.com/gp/product/B00AUB3SSA/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1 


Amazon says it is "currently unavailable" but if you search for "8p8C 
manual switch" you should be able to find other options.

You want to be sure to get a manual switch not an Ethernet network 
switch, which has electronics inside and is a different animal.

I agree with Victor's comments.  I am all in favor of the elimination of
the all-in-one, big box rigs.  No vendor in the amateur radio market can be
the premiere supplier in all areas even though Elecraft is trying hard. I
don't consider them the best panadapter HMI vendor or best paddle
manufacturer.  What I would consider ideal is a rig, computer, and other
"boxes" which sit behind or below the operating desk (or at a remote
site).  On the desk, a keyboard, mouse and/or trackball, an advanced KPod
with a few more knobs and customizable LCD keys for the major rig control
and antenna  functions and monitor(s) for the waterfall, frequency
readouts, SWR/POWER indicators, RF waveform display and logging displays.

An enclosure to corral all the miscellaneous "boxes" and their wiring would
also be nice.

Dear OMs and YLs,
     For me the K3 epitomizes modularity.   One can build the radio up over
time and purchase only those features required.   This keeps entry level
prices down and enhances repair.   From Ireland, one could return a faulty
module perhaps holding on to the K3/S and continuing to operate.    I hope
Elecraft continues this approach.   Yes and keep the power supply separate.

     I find the P3 is pretty good especially with an external monitor.
Maybe the next display will be more like what Flex offers but for me
Elecraft beats Flex in most regards.   Oh, thanks Elecraft for the K-pod.

I had a Heil FS and desoldered the 1/4? and resoldered a right angle RCA plug for the K3S. Works great!

Higher quality semi-pro audio products use RCA connectors, and high 
quality RCA (and 1/8-in) cable-mounted connectors made by Switchcraft 
and Neutrik are widely available from audio vendors like Full Compass 
and Sweetwater.

I have not seen a HF ham station that did not use RCA connectors.

For me, that would be ham radio hell. My ideal radio has knobs. A big 
one for tuning, little ones for other things. Knobs and buttons. I'm not 
knocking Flex at all, but if that were the only radio or all radios 
worked like that, I'd just do woodworking.

Some people like tuning. Some people like point-and-shoot. Knobs for the 
former, panadapters for the latter. Don W3FPR lamented earlier that hams 
no longer seem to know how to wire up a simple cable with a different 
connector at each end. I lament that hams no longer seem to be able to 
tune or enjoy the experience.

I think Elecraft understands both kinds of hams.

When asked "what is the best radio?" I think Rob Sherwood summed it up 
saying in a few words? "the one you enjoy using".

They?re not long gone, nowadays they call them Cinch connectors.  Not only Hams use them but most AVR and Stereo manufacturers.  Take a look at a High End HI-FI or AVR rear side.

Ditto.? Made mine from an old microswitch from junk box, some pine

plugged in, of course, to the antique
RCA jack on the back of the K3! ;-)

Message-ID: <001f01d4f5f0$d9d925b0$8d8b7110$@cox.net>

I have decided to sell some of my favorite amateur radio items and hopefully
find homes for them where they can be used more often than I now can use
them. 

KPA100 100 watt Amplifier

KAT100 100 watt ATU

EC2 Enclosure

The KPA100 and the KAT100 have been installed in the EC2 Enclosure making it
a perfect match to the K2 Transceiver in appearance and function.  This is a
perfectly operational unit with no cosmetic issues and comes from a
nonsmoking home.  Current pricing for the amplifier and ATU (exclusive from
the enclosure which is no longer available) is $1020.  I would like $700
plus shipping.  

 

Gamma Research HPS-1A 13.8V Power Supply

 

This supply is rated at 5 amps continuous or 22 amps at 25% duty cycle and
is able to power 100 watt RF amplifiers at normal CW or SSB operation.  Its
dimensions are 3.37" x 1.55" x 5.25" and it weighs only 1.25 lbs.  It comes
with an adapter to the K2/10 and Anderson Power Poles to the first unit
above.  Current price is $229.  It works perfectly with no cosmetic issues.
I would like $150 plus shipping.

 

Begali Magnetic Traveler Iambic Paddle

 

This key is in perfect condition both mechanically and cosmetically and has
(sadly) only been used at home.  It is designed for use in the field and has
folding "wings" both for stability and protection of the aluminum finger
pieces.  Its current price is about $290.  I would like $190 plus shipping.


 

Contact me direct (only) at:

nu4i(at)cox.net

 

I can supply photos of all units upon request and PayPal is fine.

 

Ken Moorman, NU4I

Message-ID: <001b01d4f5f2$ad91eee0$08b5cca0$@mail.dk>

Hi - 

 

I must be a complete idiot, but I just cannot get this to work for me. I am looking at my P3 connected to a K3. It is connected between the IF In on the P3 and IF Out on the K3. When looking at the P3 display, on all frequencies, I do not see the actual frequency of the VFO, I see 0, for example to top line has -25.0 0 +25.0. 

 

On top of that, when I use marker A and move it and press the QSY, nothing happens. What am I doing wrong. The User Guide just says how it should work, but not why it is displaying 0 as center frequency? 

 

Thanks, 

Robin

Robin,

Do you have an RS-232 9 pin cable connected between the K3 RS232 
connector and the XCVR connector on the K3?  That cable is what carries 
the frequency and other information to the P3.

For computer connection, connect the PC to the "PC" connector on the P3.

If you have a K3S and are operating with the USB to K3S connection, then 
you would use the CBLP3Y cable between the RJ45 jack on the K3S and the 
P3.  If you do have this arrangement, make certain the RJ45 plug is 
fully seated - push the RJ-45 plug in until it clicks, you may have to 
pull the cover back and seat the actual connector until it clicks home.

As an added note - if you have previously attempted to put the K3S end 
of the USB cable into the RJ-45 jack, you likely damaged the RJ-45 jack 
and the KIO3B option will have to go back to Elecraft for replacement.

Don W3FPR

I use the opportunity to follow up on this thread. The IF output of the K3
and K3S is centered on 8.215 MHz. 

But there is also a second IF at 12 kHz with no output. I wonder if anyone
has made an output for the I- and Q- channels at 12 kHz. It looks fairly
simple to find judging from the schematics.

Cinch connectors like RCA plugs???? Not even similar.

By the way, all those plugs and connectors out there are lacking one 
hugely great asset: An RC plug can be tightened if it becomes loose - 
just a little squeeze is all it takes. And, I would sure rather have 
several RCA jacks than a DIN plug to deal with when soldering!!!

Re VisaIia: I was interested in the new offering from N6BT (?) 40m vertical with integral ground plane, all in one rigid package. It looks very similar to a system suggested by Moxon many years ago. I tried that using wire, bamboo sticks and a fishing rod. I don't quite see how he could take a patent on it but it was a very neat package.

So I have been using my K1 for a few weeks now, radio seems v-e-r-y close to sound of my K2.

I am done with it and want to move up to a K3, anyone?  It is a 4 band K1 with the autotunes built-in.  Lighted readout.

Right -- a Cinch connector is VERY different. It has a square, 
rectangular, or round body with blade-like contacts on the male and 
receptacles on the female.

 Another update to the equipment I'm selling for Craig,NM4T.

Remaining are the K3 and the KeyLogGo with keyboard.

The price of the K3 has been reduced again.

I've added some words about the functionality of the KeyLogGo, which makes
a nice addition to any portable radio operation!

Hmmm ... not quite true.? Well, actually not even close.? For those who 
did not experience the middle of the 20th century and in the interest of 
historical accuracy:

Cinch-Jones connectors were popular back then because they came in a 
variety of conductor numbers and were easy to assemble and solder, being 
big enough [in contrast to the abomination known as DIN connectors which 
came along later].? C-J connectors are square or rectangular, the "pins" 
are blade-like [see current day automobile fuses] with a self-wiping 
action on insertion, and they had a clamp device on the cable side that 
would grip the cable outer sheath.? They had the disadvantage that they 
could be pulled apart fairly easily.? I'm sure they're still around, I 
just haven't seen one in a few years.

The RCA "Phono" connector accommodates two conductors, one of which is a 
chassis connection [or should be, see k9yc.com/groundingandbonding.pdf] 
I believe they appeared on the scene at the beginning of the "High 
Fidelity Component Era" about the time 45 and 33 1/3 RPM records 
appeared and were used for the audio paths between the various 
components of a hi-fi system. They are small, round, and you can 
increase the tightness of the shield connection by squeezing it 
slightly.? My K3 has one on the back which supplies power to the P3.? 
Nearly every TV sold at RC Willey, Best Buy, Frye's, Walmart, and Costco 
has a set of them for video and audio connection.? I like most folks 
have a dozen or so of the cables that come with those TV's out in the 
garage that are excess to our needs.

Those are now known as ?Jones? connectors. No idea why the change, but they are becoming very hard to get with demand dropping.
Easy for us to work with, but they take up a lot of rear-panel space on equipment.

I just built a Nanokeyer last night, and the connections for keyer and PTT
are both RCA jacks. However, in the documentation, they are referred to as
"cinch connectors". When cataloging the parts prior to building, I had to
look in the construction pictures to verify what kind of connector was a
"cinch" connector. I was rather surprised to see that RCA connectors have a
different name now, but RCA hasn't been a thing for a long time now so I
guess it was inevitable, seeing as it is listed as having gone defunct in
1986.

The curious can find a short two minute video of my Nanokeyer's first
testing here: https://youtu.be/_LLVS_Pk8zE
The RCA jacks, referred to as "cinch connectors" in the documentation, are
along the leading edge of the device, on the right side. Technically,
though, that's the back edge. It's just in the foreground because the cable
on my Bencher is short.

Yes. That's always been their correct name. Because of their relatively 
large footprint as compared to modern connectors, they are used 
primarily on legacy equipment. I have several '70s and '80s vintage 
"brick" amps for 2M and 440 MHz that use them.

The Nanokeyer is the creation of Oscar, DJ0MY.? It's possible that the 
RCA Phono connector is called a "Cinch" connector in EU or DL, but in 
the US [and I believe Canada], it is quite distinct from the 
"Cinch-Jones" connectors, which I find are still available from the 
several sources I checked.

Sometimes it is even a loose connection  - make sure you push the RJ-45
connector all the way in until it clicks. Sounds too stupid but happened to
me once...........

Hi - 

 

I just cannot get this to work for me. I am looking at my P3 connected to a
K3. It is connected between the IF In on the P3 and IF Out on the K3. When
looking at the P3 display, on all frequencies, I do not see the actual
frequency of the VFO, I see 0, for example to top line has -25.0 0 +25.0. 

 

On top of that, when I use marker A and move it and press the QSY, nothing
happens. What am I doing wrong. The User Guide just says how it should work,
but not why it is displaying 0 as center frequency? 

 

Thanks, 

Robin

I like them because I can get my arthritic hands around them and in the
days when a soldering iron was not a "weapon of mass destruction" in my
hands they were so easy to solder wires to.--

Here's what I use.? It allows switching up to four sensors to one P3:

Amazon says it is "currently unavailable" but if you search for "8p8C manual switch" you should be able to find other options.

You want to be sure to get a manual switch not an Ethernet network switch, which has electronics inside and is a different animal.

Message-ID: <CALdHbXjKLi4-cWuX-O9eyUtsbxRBfEFEqHRdoeDTEAHfPQ7sOw@mail.gmail.com>

Hi all,

I have a K2/100 and a K2/10.  I noticed that K2/100 is having an issue with
the frequency calibration, so I decided to fix it today.

When I set the band to 10m and connect my external GPSDO frequency counter
and the FCTR probe to TP1.  The internal counter keeps changing its
frequency while the external counter shows stable reading, so it seems that
the issue is actually with the internal FCTR.  Also, I cannot match the
external and internal reading by turning C22.  It is way off.

Any idea?  I was following the instruction from the link below;

Chris,

Is the K2 CAL FCTR reading steady when you measure TP3 with the internal 
probe?
If not, there is something wrong with either the internal probe or with 
Q9 and Q10 on the control board.  Replace CB Q9 and Q10 with PN2222 
transistors and see if that corrects the reading.

Once you have a steady reading, you can proceed - but not before.

Hi Robin,

Make sure you have the P3 and K3 connected via the 9 pin RS232 cable, and that 
both are at the same baud rate mentioned the manual.

Also, in the P3 menu there is an entry for radio type. Select K3 if it is not 
already entered.

Subject: [Elecraft] RCA Connectors i.e Phono Plugs
Message-ID: <201904182340.x3INedmk020677@mail41c28.carrierzone.com>

I'm an old ham (60+ years as a ham):

Originally called RCA and Phono connectors (I still refer to them as 
that).  Back of my K3 has a couple.

My brand-new, cutting edge, made-for-ham radio, super, A/D convertor* 
has four of them to take two IQ  baseband inputs from two SDR's to 
convert to digital via USB2 port on a computer.

Its replacing my old M-Audio Delta44 soundcard (which had four 
1/4-inch mono phone plug inputs).

I bought four 3.5mm mini-phone plug to RCA/Phono male connector audio 
cables (6-foot) from Amazon to accommodate connecting the A/D to my 
two LP-Pan's which are connected to main and sub-Rx IF's of my K3.

 From Wikipedia:

"An *RCA connector*, sometimes called a *phono connector* or (in other 
languages) *Cinch connector*, is a type of electrical connector commonly 
used to carry audio and video signals."

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

It was news to me that an RCA phono connector is also known as a "Cinch 
connector".? I think you're right that it must be a name used in Europe.

Never were in UK to my knowledge, we always called them phono plugs and 
sockets.

Jones connectors were always the black cased multi pin connectors with 
rectangular blades, usually some at right angles to others. Think FT101 
power connector.

I think Cinch was a manufacturer of Jones connectors at one time. Cinch 
belongs to Belfuse now I think and they still make a lot of military 
grade connectors, not Jones connectors though I suspect.

Here's an interesting history of the Jones connector found in a mail 
back in 2012 on the Gearslutz web board.
https://www.gearslutz.com/board/geekslutz-forum/673980-cinch-jones-connector-whats-deal.html


Martin, HS0ZED



Hi. I'm not sure how i found this web site, but let me try to answer the 
question.

My grandfather invented the first Jones Plug . I believe it was in the 
early 1930's. His name was Howard Bevan Jones. He also manufactured lots 
of different kinds of Jones plugs, with a company based in Chicago that 
bears his name. At the height of the company's existence, it had about 
200 <https://www.gearslutz.com/board/gear.php?id=48746> employees. the 
early catalogs have LOTS of Jones Plugs.

At some point, Howard B. Jones and Co. was bought by Cinch 
Manufacturing. For a number of years, the plugs were still called Jones 
Plugs, but later on they were sold as Cinch Jones Plugs.

I , and others in my family, have old catalogs, photos of the whole 
group of company employees, and lots of other memorabilia. My uncle, 
Howard's son-in-law, tells tales of driving all over the Midwest to sell 
them. Very entertaining. this uncle died at age 100 a few years ago.

I have tried in vain to find out a lot more. Cinch Mfg. was no help. 
Even the family was quiet about what actually transpired in the early 
days. Family lore has it that Howard also invented, and his company 
manufactured, a device in slot machines that allowed the owners of the 
machines ( casino owners, presumably) to adjust the odds of winning. You 
can extrapolate whatever conclusions you find interesting from this 
information.

Howard also invented the child's toy called the Hootnanny. It was widely 
used, and is available from time to time on eBay 
<https://www.gearslutz.com/board/gear.php?t=eBay>.

I could go on further, but perhaps this answers your question. I will be 
interested if any other comments arise.

Michael Bevan Jones

Sorry for the typo in the first line - the ETS2 is the standard 3 inch 
tilt stand, the ETS15 is the 1.5 inch short tilt stand.

It is normally used with the KAT100 when the K2 is stacked on top of the 
KAT100, but it can be used in other configurations as well - owner's choice.

Because they are not locking and will separate if pulled, on more than

If I remember rightly (and it's been a LONG time) there was an outer 
shell pair made for at least some sizes which locked together external 
to the shell.? Even without the lock, the multi-pin models (especially 
in the larger sizes) took some umph to get them apart.

There is an easy locking device that can be added to any Cinch-Jones
connector.
The ones used on the older Yaesu radios had this device included.
You would have to practically destroy the chassis to get them apart if you
didn't squeeze it properly to dis-engage the lock.

Much tighter and higher current rating than those Anderson power poles
everyone seems to have fallen for.

Because they are not locking and will separate if pulled, on more than once

You remember correctly.? And they can require a tussle to separate on the bigger

I'm on the Page 62 Resistance Check and R115 / 12V IIN check should be >500
ohms and I'm getting 132 ohms.  All other checks in the table are fine.

Before I move on to Alignment and Test Part 2, I want to get some feedback

OK - I check this again after moving the board off my antistatic mat and
onto the manual, and power cycling the multimeter, and how I'm getting 3.6k
ohms at this point.  So all OK.  Not sure what this issue was that moving
the board or power cycling the MM solved.

I found that when both my external FC probe and the probe provided by the
kit were attached to TP3 the K2 frequency reading was lowered significantly
(~12070 from about 12098) vs when measured separately.  C22 could not make
a match.  Separately the two measurements were fairly close, and I could
use C22 to make them the same using the hold feature on my external FC to
capture it's reading, and adjusting C22 to match it on the K2 with only the
kit probe attached.  Is this OK?  The manual talks about having both
connected at the same time, but the interaction of the two was an issue for
me.

Mark,

What kind of probe are you using on your external frequency counter?
You should be using a 10x probe like you would use on an oscilloscope to 
keep the loading of the circuit by the probe capacity to a minimum.

It appears from the schematic that the Elecraft 144-450 MHz Directional
Coupler for the W2 SWR/Power Meter can safely pass DC voltage without any
direct interface nor danger of damage with the sensor electronics.  My
question, has anyone confirmed that the VHF/UHF couplers are safe to use
with 12VDC in-line coax powered preamps (i.e. Icom AG-25/35 preamps with an
Icom IC-9100 Sat Transceiver).
Thank you,

Good Afternoon All,I have a Cirro Mazzoni Baby loop antenna and would like to
take advantage of the RS232 module with my KX3.  Of course, I have no
problem with this interface using my K3.  But I was wondering how one would
go about creating a RS232 interface using the KX3.  Would a simple RS232 DB9
9 Pin Female to USB 2.0 PLC Serial Straight-through Cable work with the KX3? 
It seems so but I can't figure out how to get from the USB end of that cable
to the ACC input.  Am I looking at this the right way?ThanksMarkKK2L

BNC with mini test clips.  I can switch in 10x (or 1x) on the FC but that
doesn't make any difference.

FC is a BK Precision 1823A.

Message-ID: <201904211751.x3LHpTbF021343@mail46c28.carrierzone.com>

Cinch-Jones always referred to square black connectors with large "blade" pins.

They were used a lot with early ham amplifiers and until recently in 
Ham-series rotator controllers; now they come with 9-pin round 
connectors populated with 8-pins which one crimps onto rotator wire 
and inserts (like a Molex connector).  One has to have special 
removal tool to pull the pins.  I recently bought a Ham-IV and T2X 
rotator with those used at the rotator.  Control box still uses 
Cinch-Jones 8-pin.  Older Ham rotators sold by Hygain (and CDE) had 
simple screw strips.

I bought one of W6PQL 2m kilowatt amps and it came with a 12-pin 
Cinch-Jones, which is great since the amp draws 40A at 50v thru the 
pins.  I paralleled two pins to be sure to handle current.  Other 
pins carry 12v for control board and several lines for remote 
monitoring/control.

I can still find them in internet searches (usually Amazon companies).

Internet search shows pictures:
https://www.bing.com/images/search?q=cinch-jones+connector&qpvt=cinch-jones+connector&form=IGRE&first=1&cw=1129&ch=508

You will note some pictures show RCA-phono types with Cinch name.

Interesting history given in recent link.

Other "old" connectors used in ham radios were Octal Plugs (on many 
Heathkits) and 4-pin mic connectors.  These days one finds computer 
type connectors in use.

Does anyone know how to hook up the proper cable,?, to run an SDR like HDSDR on the KX3 withthe PX3 also hooked up. We are also using the KXPA100 amp.
I know the end that fits in the IO R on the PX3 is a 2.5 mm? can I use on the other end a USB A.Where might I find this cable??I only have USB connections on my Asus Laptop.

When using the KXPA100 amp with the KX3 the control is via the amp. USB to
3.5 cable plugs into the amp and feeds through to the KX3. No computer to
KX3 cable is needed, just computer to KXPA100. Same cable you would use on
barefoot KX3.

There used to be (and there may still be) in the Cinch line, locking 
Jones connectors with steel tabs on each side with released when you

The I/Q feeds through the PX3. You need to take the I/Q out of the PX3 and
send it to a high quality sound card, usually a USB sound card.

If you want wideband, choose a 192 kHz card from here:

http://www.telepostinc.com/soundcards.html

I use a U7.

The rig control also feeds through the PX3 and the amp to USB on your
computer.

Mark,

I am not talking about the 10x/1x sensitivity scaling of your frequency 
counter itself.
I am referring to the capacitance of the probe itself.? You should be 
using a 10x 'scope probe which has a low capacity and will not load the 
PLL Reference circuit.

Hi Don and Bert,

as I noticed this evening > troubleshooting nor alignment parts are not same
in the different Rev. of K1 manuals. 

Our sick K1 is also from 2000... RF board Rev. D, 2000 so I am using the
manual Revision D, Dec 1, 2000. 
Unfortunately when I measured the resistances on page 45 (J7, J8 test
points) I found the J7 pin 6 has 5.6kOhms to GND but table on page 45 says
it should be >100k. 
What makes me confusing is that when I opened the later manual Revision F,
January 24, 2002 I found that in the same table on page 45 the value of J7
pin 6 should be 5-7kOhms which souns ok compare to my measured value
5.6kOhms... ?!

Don can you let me know some hints what it could means in that case please?
The rest values are same in both tables and measured values are also
corresponding to it. 

Bert I will send you the proper manual for your K1 (we have same Rev. ) >
Revision D, Dec 1, 2000 by email. 
I got it from Don (many thanks Don!!)

Thanks for help in advance. 

73 Petr

Hi,

Chose instead the U5. It is slightly less money and is just lacking a bunch
of fancy audio features that have no use in a panadapter. Also all the
cables come out on one side which makes for neater cabling. 

I believe Asus has overcome its early failure problem(s). I have had mine
for at least two years and no failures have been posted her for a long time.

Mark,

First check the DC voltage on U6 pin 5.  It should be near 4 volts - if 
not, you have a problem on the thermistor board, likely a solder bridge.

Then recheck the PLL reference oscillator range at TP3 using CAL FCTR. 
Tell me the high and low frequencies.

Then check the VFO frequency at TP1 (using CAL FCTR) when tuned to 
4000kHz and again when tuned to 7100kHz.

Mark,

You will likely have to gain access to a full RS-232 port by using a USB 
to serial adapter.  Connect that to an RS-232 "Y" cable.  One side of 
the "Y" connects to the RS-232 of your loop antenna, and on the other 
side of the "Y" connect to your KX3 using the KXSER cable from Elecraft 
- or alternately, build your own KXUSB using the schematic shown in the 
back of the Elecraft XG3 manual (download it from Elecraft).

Make certain your loop controller only listens to the RS-232 
communications.  If there are RS-232 drivers in the controller, they 
must be disabled (not just turned off, but disabled by disconnecting 
them or disabling them by the use of Tri-State output devices.

Tomy,

The KX3 to KPA100 cable assembly and the KX3 to PX3 cables are involved. 
  The PC connects to the KXPA100 using the KXUSB cable to control not 
only the KXPA100, but the PX3 and the KX3 as well.

In other words, the PC cable connections are "daisy-chained"  From the 
PC to the KXPA100 first, and then to the PX3 and then on to the KX3.

Petr,

Do you have the filter board plugged in when you read 5.6k ohms?

Note in the Revision D manual, the filter board is NOT plugged in when 
making the resistance measurements on page 45.

The filter board is not plugged in until you get to page 46.

Hi all,
The ATF34143 Phemt used on the rx input is discontinued and I just wondered what the suggested replacement would be for this little gremlin. I've Just purchased a second hand XV144 and I'm not getting any variation when I adjust c1 and it looks like the 34143 has already been changed looking at the state of the solder.
Any guidance would be much appreciated.

Tried a 10x scope probe and that did the trick.  Thank You!.

I'd try a PGA-103+ as a retrofit... plenty of them around.

Hi all,
The ATF34143 Phemt used on the rx input is discontinued and I just wondered
what the suggested replacement would be for this little gremlin. I've Just
purchased a second hand XV144 and I'm not getting any variation when I
adjust c1 and it looks like the 34143 has already been changed looking at
the state of the solder.
Any guidance would be much appreciated.

Greetings all,

How could I use the KXPA100 amp with my K2? I don't think the K2 has a keying line, and so I wonder if the KXPA100 would automatically detect band and frequency through the built-in tuner without a keying line cable. Any info appreciated.

Two separate comments:

  As I understand it the KX3 has a serial port, used for control and
  firmware updates, but it's a mini stereo phone plug.  This is what's
  on the end of the KXSER and KXUSB.

  Be careful about "RS232" vs "TTL level serial".  True RS232 has
  voltages from +3 to +15 (or +25, depending where you read about it) V
  and -3 to -15 (-25) V.  What is typically used is "TTL serial", which
  has 0V and 5V (for a 5V system; sometimes it is 3.3V).  Input circuits
  may or may not tolerate the higher voltages.  On a RPI you should
  definitely be careful


It appears that the Elecraft serial ports are ok with the full range
possible with conforming RS232 signals on receive, but use 9V
(conforming) and 0V (not conforming) on transmit.  That is almost
certainly ok because there is so much "TTL serial" that a robust
receiver has to treat 0 V like it is -3 V.

Subject: [Elecraft] K2 - Bar Graph Erratic
Message-ID: <CAAfqLSAx=cEwfrALiyXv13p6VSDjNCEEMasK1uorwBCRdsx9gg@mail.gmail.com>

All,

My K2 has been out of service for an extended period.  Today, I put it back
on the air and it appears to function properly, except for the bar graph
display which is erratic.  When I rotate the rf gain control counter
clockwise segments begin to illuminate until the 3rd is illuminated.  As i
continue to turn the control no more bars illuminate until I reach about
the 9 o'clock position and then the remaining segments turn on.  When I
turn the control clockwise the segments remain lit until I reach about the
2 o'clock position and then they begin turning off.  This is one of several
patterns I see.  Some times all the segments turn on and stay on and at
other times, only the two left most ones turn on.  Receiver gain seems to
change in relation to the RF gain control's position.

Transmitter seems to work fine, as I made about 20 CW qsos on 20 meters
this afternoon. To me, the issue appears to be a in the bar graph/control
circuitry. Any suggestions as to where to begin troubleshooting?

HI Don and Petr,

Thanks for the offer Petr but Don has already been kind enough to send 
me the Rev. D, 2000 K1 Manual. Thanks anyway!

I find it quite difficult sometimes to troubleshoot and follow the 
schematics. Also doing signal tracing in the receiver and
transmitter is quite subjective using only an RF probe. It would be 
better to have some RF values p-p so you could use
a oscilloscope and at the same time see the signal.

This is an older radio so I don't expect Elecraft to come up with some 
new troubleshooting aids, but the K1 owners can
share experiences and test results.

I've just measured the resistance between J7-pin 6 to ground and it's 5.7K.

Please keep me in the loop. Thanks to both of you. Comments from other 
k! owners are appreciated.

Thanks!

Bert VE3NR

Bert,

Multiply the RF Voltages listed for the RF Probe by 2.8 to get the peak 
to peak RF voltages observed with an oscilloscope.

Robbie,

It sounds to me like you have an RF Gain Control that is worn.
Sine it has been out of service for a while, you might be able to 
restore it by rotating the RF Gain knob through its rotation 10 to 20 times.

If that does not correct it, then replacing the control is the only option.

Jay,

You will need to key the amplifier with a keying output from the K2. 
Yes, the amp will detect band and frequency, but you still need a KEYOUT 
from the K2.
The best solution is to use the N0SS Amplifier Keying board.  Since Tom 
is SK, no kits are available, but I understand you can obtain the boards 
from FAR circuits - or the circuit is simple enough that you can build 
it on perfboard using Tom's full size board layout.  See 
http://www.mmccs.com/mmarc/n0ss/k2_t-r_rly_drvr.pdf.

Thank you for your help at RARSfest - the Amazon package arrived today - 
Thanks.

Chris,

Have you tried ordering the part from Elecraft?  I am assuming they 
still have some in stock.  Email to parts at elecraft.com with the part 
number and description and you should receive a return email with the 
cost.  That will allow you to use the Quick Order form on the website to 
order and complete the purchase.

I thought I was imagining it.? But every time I replied with a ? or a 
new CQ I would get the same response.? Then on forty meters Brian 
admitted he was trying to work me with 12 watts.? On the second band he 
was easy copy even with the deep QSB.? Dave was in the noise too but his 
call sign is very recognizable.? It seems to flow over the QSB somehow.


 ? On 14050.5 kHz at 2200z:

W0CZ - Ken - ND

K6XK - Roy - IA

K4JPN - Steve - GA

K4TO - Dave - KY


 ? On 7047.5 kHz at 0000z:

AE6JV - Bill - CA

K0DTJ - Brian - CA

K4TO - Dave - KY

K6XK - Roy - IA

K6PJV - Dale - CA


I am glad the sun was active over the last two weeks.? Conditions are a 
little better.? The solar forecast is for another full year before any 
increase in sunspots.? Good time to test your weak signal techniques and 
buff your antennas.

 ?? Until next week 73,

Hi Don,
I had thought about it, but it's a long way to send it and figured i should be able to find something more local.
The Doc's suggested an equivalent which I can get ( I'll get a few just in case), so will give it a go and see if fixes it. It certainly down on sensitivity, my IC7400 is better on 2m at the moment.
Thank you for the quick response, very much appreciated.

You are correct Don, Far Circuits does have the board for the N0SS  amp
Keying circuit.  I have installed it in both of my K2's and works great.
They also have the board for your fixed Audio out.  They are hard to find on
his web page so I just called him and he took care of my order.

Don (and Ed and Heinz),

Thank you for the information. I have Tom's legacy website so will look up the board. 

Don, I enjoyed my day with the Elecraft gang at the hamfest; thanks for the invite. I'll see you at Dayton, if you can make it.

Currently, the K3 VFO A switches to the new band when selecting a new band
but VFO B remains on the previous band.  I can see where that might be a
good thing for certain contests but how do I set the default VFO B switch so
that it follows A or so that it also switches to the new band?

Have used my K3S for less than 3 months and have decided to go a different
route, so am selling the K3S, P3 and speaker. The radio is the loaded
version--meaning the DX'er/Contester version and has the latest software
updates in it. Bought it all new at just over 6200.00 dollars and will sell
at 4995.00, plus shipping. Get ahold of me at off reflector e-mail.

Hi Greg,

I am afraid that depends on the VFO Setup in the Config Menu.

VFO IND, if set to YES, allows VFO B to be
set to a different band than VFO A.

I'm thinking of putting the KPA1500 RF deck and PSU out of arms reach but
still in the shack to reduce their noise impact. I'll use the KPA1500
Utility if I decide that works for me.

If it doesn't make a real difference in noise I'll just revert to "normal".

Message-ID: <1E4E94BC-C14A-4649-AAE2-197591AB45BF@gmail.com>

So I purchased a used K3, it arrives in a few hours.
Trying to get smart before I unbox, I recall the past user removing the 6kHz filter and leaving in the 2.7, 500 and 250kHz filters in place.
Somewhere tonight I recall reading that all the filters need to be in descending order.  The fact that the 6kHz filter is no longer in there is leaving a ?space? for it in the receivers (it has two receivers in it) is that still ok?

 Robie,
My K2 had the same problem that you described?after a long period of not being used.? After severaldays of?being left powered on? and daily use, the problem went away.
My theory is that bypass capacitors in the K2 may have "reformed" and eliminatednoise in some circuit that was affecting the S meter bar graph.
As Don says, it could also ?be a noisy RF gain pot.

Even though the K2 is a dated design it is still a great rig. I would never part with mine.

Wes,

FYI, my K2, S/N 7225, also has a faint birdie in about the same spot, but only with the antenna hooked up, listening to "white" noise. There are several birdies in all bands with no antenna, but I can only hear most of them with the AF and RF Gain pots maxed out. 

Most will disappear underneath a received signal (even noise), but there are a couple that are loud enough to hear with one. It's not been a problem for me.

Yes...I operated a K3s for several months with the 1st filter position open.? The K3 will need to be instructed that the position is open.? The free K3 utility software will help you do that.? When you set up the radio the first time, follow the manual for setup/calibration and you will find those instructions on how to do that. You will also want to check to be sure the radio is on the latest firmware which that software can also do for you.


The you can save the current config for safe keeping.

Jim ? you may have to put the RF deck and PSU a bit farther than out of arms reach.  I have my PSU on the other side of a nearby wall (in a utility/workshop room) and so that unit is completely quiet.  With headphones, the RF deck fans can?t be heard, although I am considering relocating the deck to where the PSU is.  I do like the remote utility program, but I really would like to see a KPA1500 hardware remote unit?something like the ACOM 2000 uses. I would buy one of those in a minute.

If it doesn't make a real difference in noise I'll just revert to "normal".

Thanks

Afternoon all:
I purchased the following items in hopes of setting up a portable QRP station/coms go kit of sorts  with the Yaesu FT817ND, however I'm finding that work and family commitments leave me little to no time for the hobby. I also recently obtained a KX2 which also streamlines my QRP aspirations a bit in the event I have the opportunity to operate. Since I don't need the gear redundancy at this time, I'm offering the following equipment in like new condition. Please reach out with any questions. Payment via Paypal, Square Cash, or alternative electronic means is preferred. 

	Item       : T1 ATU (Factory Assembled)
SKU        : T1-A
Quantity   : 1
Original Item Price : $159.95
Asking Price: $120 shipped
	Item       : FT-817 Remote Control Adapt. for T1
SKU        : T1-FT817

I don't know what you are missing but, when I was investigating the QSK keying characteristics of the TS-590S, I found a digital storage scope to be very useful.   Traces showing key input to rig, amplifier keying output, RF envelope, and RX audio were very informative.

At 30 wpm the first element of your call should be 120 ms long so there would have to be a really bad delay for it to disappear completely.   I doubt many could detect the loss of the first 8 ms.

A 'scope will tell you where the delay is happening if no one comes up with an answer for you.

Hi Pete
I had this problem as well - it is a "feature".
It occurs if the rising edge of the keying waveform happens at the same time as the PTT line.  The ONLY way around this is to delay the keying waveform slightly so it occurs after the PTT.  If you are using a WinKey, then set the "lead-in" delay.  There is also a feature in N1MM to achieve the same result.

Try sending your callsign as TN4ZR :)  I believe TX Delay 8 is  
technically less than 8ms however I am guessing that is not your  
problem since the KPA1500 is very fast. It would help if you gave a  
description of how you are sending CW.

"It occurs if the rising edge of the keying waveform happens at the same time as the PTT line.  The ONLY way around this is to delay the keying waveform slightly so it occurs after the PTT."

That would seem to imply that you are not using CW VOX keying.  If that is the case then wouldn't using CW VOX eliminate the issue?

to using other means to key the radio and amp and send CW, those may 
have their own settings as required.

While I do not consider myself a high speed CW op, I do work QSK. ? I do 
not find any truncation of the first CW element.??? I use the internal 
keyer and either a Vibroplex Iambic paddle or a Vibroplex single level

Hope this helps.

This appears to be, at least in part, a simple matter of RTFM.? Also, my 
manual is 9 years old, and there's obviously been a lot of stuff added 
since then. Experimentally, it appears that must have *both* QSK on - 
whether Full or Semi - and VOX on.? Once I do this, I see my first dots 
on the KPA-1500 bar-graph every time.? I do not want to use the built-in 
keyer in the K3, because most of my operating is CW contesting, and I 
want to use the Winkeyer to send stored messages from N1MM +.? The 
manual makes it clear (if only I'd read it) that both QSK and VOX must 
be enabled for CW. In PTT mode, it appears that my keyer is sending the 
PTT signal simultaneously with the first RF - not good.

Thanks to everyone who helped put me on the right track.

I know this will seem incredible to the software purists, but I have an 
actual mechanical "switch" in series with the PTT line. The K3 is always 
in QSK mode, but if I get tired of all the racket, I can just turn on 
the PTT. That seems to work flawlessly with the KPA1500, as well as my 
old tube amplifiers. (There's another switch in the keying line, just in 
case the computer goes nuts. Of course, that could NEVER happen.)

Scott,

What do you mean by "if I get tired of all the racket"?
The Elecraft gear is all electronic switching for T/R, so no relay 
clacking racket.  That is true for ALL Elecraft gear, even the oldest K2.

That may not be true for your old tube amplifiers, but the original 
question was about a K3 and a KPA1500, so no relay clacking could be 
present.

Hi Pete 
If you don't want to use VOX and/or QSK ............  I take both the key line and the PTT line from the WinKey to the K3.
In N1MM - Config - Config Ports etc - WinKey - Set lead time to 1.  Works perfectly !!

This appears to be, at least in part, a simple matter of RTFM.  Also, my manual is 9 years old, and there's obviously been a lot of stuff added since then. Experimentally, it appears that must have *both* QSK on - whether Full or Semi - and VOX on.  Once I do this, I see my first dots on the KPA-1500 bar-graph every time.  I do not want to use the built-in keyer in the K3, because most of my operating is CW contesting, and I want to use the Winkeyer to send stored messages from N1MM +.  The manual makes it clear (if only I'd read it) that both QSK and VOX must be enabled for CW. In PTT mode, it appears that my keyer is sending the PTT signal simultaneously with the first RF - not good.

Thanks to everyone who helped put me on the right track.

Denis,

Are you referring to the K1 LCD Backlight Kit for a built K1?  If so, I 
have one available.  $29.95 plus shipping.
Please let me know if you want it and I can compute the shipping cost - 
USPS Priority Mail.

Don,

I use an external vacuum relay for compatibility with my old tube 
amplifiers. The whole system long predates the KPA1500, and I still 
sometimes use the tube amplifier. The system also includes small relays 
for switching receiving antennas and protecting the receiver. However, 
even without relays, in QSK there's sound from the receiver between 
characters, of course, which I sometimes prefer not to listen to. This 
works fine with the K3, as in QSK/VOX mode closing the PTT circuit 
simply keeps it in transmit mode. My old FT-1000D doesn't work that way, 
and it's a pain: if you close the PTT circuit in QSK mode, you get a 
carrier. I'm glad the K3 doesn't work that way.

73,
Scott K9MA

Problem (described below) with the WSJTX program (the "home" of FT8)
trying to access K2.  I didn't get an answer on the WSJTX Yahoo group so
I'll try here.

Configuration:

Dell Laptop PC with iMic and RigBlaster Plus connected to Elecraft K2.
Both  the Elecraft and RigBlaster serial ports connected to the computer
are 9-pin "RS-232" wired ports and all drivers are current.

With PC running Windows 7, both MixW3 and WSJTX  2.0.0 using identical
CAT control and audio settings ran without problems.

After upgrading the computer to Win 10 with no other changes, MixW3 runs
properly but WSJTX 2.0.0 and 2.0.1 did not.  The error messages from
Hamlib are:

(Tune) "IO error while opening connection to rig"
(Test CAT)  "Communication timed out while opening connection to rig"

In additions, the frequency readout on the WSJTX UI has reverted to all
zeros.

Are there "permission" settings in Win 10 that didn't exist in Win 7?

Has anyone experienced this with Win 10 and found a solution?

I'm having similar problems after going from Windows 7 to Windows 10.??? 
I'm using a KX3 on FT8 with WSJT-X, cheap $10 Sabrent USB Soundcard, 
nothing in the 9-pin RS-232 wired port of a Dell Inspiron 3670.? It all 
works well most of the time, but ... .

Occasionally I? get one of the two error messages you show.

My conjecture is that is has something to do with the COM ports, or 
shortage thereof.? The KX3 utility lists only one, COM3, when I try to 
download to the KX3.? It appears the COM3 port was taken over by another 
peripheral, maybe a printer?? Sometimes a reboot of the PC fixes it, but 
it would be nice to have a permanent solution.

Can you communicate to the K2 using the K2 Utility?

I have similar problems with my Win7 64 bit machines. It's tough to configure any additional COM ports, everything seems to eventually default to COM 3, and I can't make any changes "stick". Using only one "COM port"device, Sometimes just unplugging, and re-plugging that device, or stopping and restarting the desired program will make the computer see the connected device; sometimes,not. 

I asked my brother-in-law, a Windows systems guy, what he would do, and his reply was that he basically does what I've been doing, but then explained about some "advanced stuff" that he would help me with, but that I shouldn't try them myself...

Make sure there's nothing else using the COM port, and see if the program will work (if you haven't already done that).

Good Luck. 73, Jim KO5V

With Windows, DEVICE MANAGER is your friend.  Having it open and on screen, you can plug in devices or unplug devices and see, in real time, the port they are using.   This will then be the port to assign in an application.  Also check the parameters of the port to assure the device can communicate with the port.

Hi Bob,

I use Device Manager, and I've done what you described. However, it doesn't always seem to work. Sometimes the device ignores the COM port selected in its program and D.M, sometimes the settings won't stay selected after I close the program. Do I need to use Device Manager each time I start a device?

Thanks. 73, Jim  KO5V

Sometimes you can disconnect the cable and then plug it back in and Windows will recognize the device. In other cases you will need to power down the device and back up in order for Windows to recognize the device. 

Some assignments are sticky and will remain, while other cases it will be necessary to assign a port number every time.  That is controlled in the device driver code and the way Windows handles port assignments.

Thanks for the confirmation.? That's exactly consistent with my 
experience.? It's just too bad it has to be that way.

Windows will usually assign the same port number IF you plug it into the 
same USB port.

You can go into Properties for each device and change the port number - 
COM1 and COM2 are usually reserved for serial ports on the motherboard, 
even if no RS-232 ports are present on the board.

Don W3FPR

My Window10 computer has 4 USB C ports and a 7 port USB3 hub.  I have 5 different Elecraft USB Serial ports connected and they always receive the same com port number regardless of which USB port or HUB port they are plugged into.  K3s, KAT500, KPA500, KX3, SG3 and other non Elecraft devices.

I have never had them change as a result of a Windows upgrade.

Problem with the P3 resolved with the help of Eric.  When an owner of the
company calls to assist, that is beyond the pale.  I don't recall anyone
ever having a corporate officer from Kenwood, Yaesu, or Icom call to assist
in a problem resolution.  So, I am withdrawing my for sale offer for my
K-Line.  This time I will remember to include my name and call sign.
Thanks for reading.

Interesting.

Using Windows 10 Pro I have one radio {model/brand} if I plug it in, set 
the application to communicate with the port as defined in Device 
Manager, all is well.? I can then turn the radio off and then back on, 
changing no cables or ports, and find the same application will not 
communicate with the radio.? Then I look at Device Manager and find that 
the port number has changed.? I change the port number in the 
application and all is well........until next time.

And with another radio {Elecraft K3S}, I do not find that changing the 
physical USB connection on the computer will cause the communication 
port number to change.? Hence the port assignment is sticky.

This says to me all USB drivers are not created equal.?? And likewise, 
I've experienced no issues being the result of Windows 10 updates.

Message-ID: <CA+ZptLk6_K9WaVC1E0dZBOjk+1vdN4jrBTQMn90+Q41q34YTMA@mail.gmail.com>

I'm trying to track down a pretty obnoxious audio problem on AM, and to a
much lesser extent on SSB.

On transmit I get an audio buzz with the highest spikes on 350, 470, and
830 Hz.

At first I thought I had a ground loop hum, so I disconnected everything
from the K3s except the antenna and switched the power over to battery
only.  It made no difference.

Other things that don't make any difference: lowering the mic/line input
level to 0, changing the mic input among front panel, rear panel, line-in,
changing frequency, changing output power all the way down to 0.1w, turning
off all the lights and shutting off any other nearby equipment in the room,
running into a dummy load with the receiver nearby.

Physically touching the case or grabbing the barrel of the front panel mic
connector actually does cause the buzz to get just a little softer.

I generally use solar/battery power, though my ground is bonded to my
utility ground.

Any other ideas?  I'm running out of them.

That was my second thought, but then I disconnected everything, including
the microphone, and it made no difference.

I suspect either a bonding problem or a problem with the wiring of the mic.

I suggest that you carefully study either N0AX's recent ARRL book on 
grounding and bonding, or the slides for talks I've given at Visalia and 
Pacifion.

Again, the problem persists with all inputs completely disconnected and the
mic gain set at 0. And running solely on a battery into a dummy load.

Message-ID: <F3C4936B-C444-4D49-B22B-CA9CBFA22DFD@gmail.com>

On weekends here in the Midwest there are many AM nets (as well as the normal 3.880 Nets) that I like to listen to.
I am curious as a CW guy, I would like to not take away from my already compliment of filters, 500, 200Hz to put in 6 and 13kHz filters, thinking of adding just the 13kHz filter.   I also do 52.525.
How would the 13kHz filter work for listening to AM?  I assume I can start with that filter and use the variable to neck it down?  Most of the signals are above S-9 that I listen to.

Phil,

I've got my K2/100? running under Win10 using DXLabs Commander.??? I
could never get WSJT-X running the K2 directly using the built in Hamlib
settings, or with Omnirig or Flrig.??????? It works fine, and I was able
to create custom controls for Commander to adjust the power if I'm
running remotely using VNC.

What is entailed in installing a DVR into the K3? Sadly, I have to Move 
the KPA-500 and a PalStar manual (large) tuner before I can even get to 
the K3, For me, this is a big job. So thought I'd ask before I blindly

It?s fairly involved to add after the fact.  Not difficult ? but considerably more than ?pull the cover, plug it in?.

Frank,

You can certainly use the 13kHz filter for listening to AM - even for 
transmitting.
It also works for FM as well, so the 6 kHz filter does not have to be 
present.

Grant: thanks for the link to the install manual. WOW!? I don't see that 
in my future - too many places for errors. My K3 is not broken and I 
don't want to break it. Thanks again.

Of course, I could always sent the K3 out and have all the updates made 
and the DVR installed. But, all I operate on is 75 meters these days and 
really see no need for the updates. Again, the K3 is working wonderful.

This morning just for yuks, I also temporarily disconnected the ground from
the rig entirely while also connecting only to a dummy load, so there could
be no path to ground at all, let alone multiple paths.  No change.

I guess the next things I'll probably try are a full factory reset, and
then perhaps popping it open to make sure nothing has come unseated.  But
first I'll drop a line to Elecraft support too.  I've seen a number of
people post about similar problems that either magically resolved
themselves or ended up being a fault on the audio board.

I did listen and look at my K3S on my SDR receiver in AM mode. I do find 
there is a small amount of hum on the carrier.? Then switching to LSB, I 
do not find the hum present.

You may want to check the settings of your TX EQ. ? If you have any low 
frequency boost, that will contribute to the level of the hum. ? My 
operating values are: 50 Hz = -16 dB , 100 Hz = -16 dB , 200 Hz = -16 dB 
, 400 Hz = -6 dB, everything above that is set to 0 dB or flat.? The 
mike is a Shure SM-58.

In AM mode the hum is noted at 120 Hz, 240 Hz, and 360 Hz, all multiples 
of the 60 Hz line.? At the same time, the hum level of the individual 
frequencies, worst case,? is some 40 dB below 100% modulation.? Some are 
50 dB below 100% modulation with the worst case being 120 Hz. ?? In 
working several AM stations over the past year or so, I've not had any 
comments regarding hum on the carrier.??? These tests were done with MIC 
level set to 0 and COM level set to 0.?? Everything else normal and 
connected to the radio. ? Different power levels, mike level and comp 
level? made no difference in the amplitude of the hum components.

"Beyond the pale" is an infrequently used idiomatic expression (at least in the U.S.), probably misunderstood by many. I believe it is used in a negative sense for the most part, but clearly that isn't what the writer meant. 

Some English words have become completely useless in practice, like "semiannual" and "biannual," either of which can mean "twice a year" or "every other year." In fact if you look up the definition for one, you often see the other shown as a synonym.

Beyond the pale - outside the safe area protected by the British in Ireland. Normally taken to mean immoral, dangerous and probably obscene.

Andy,

Wayne was right, I meant that Eric had gone way beyond what was expected,
in a good way.  My understanding of the phrase was it meant beyond bad
things and into the good.  Sorry if you saw it otherwise.  Guess I better
watch out for the wordsmiths.

If you don't want to transmit but only listen, SSB mode works just fine 
with 2.7 or 2.8 kHz filters.

13 KHz filter works very well for AM. It provides +/- 6.5 KHz at
IF which is plenty for even the guys with converted broadcast rigs
that are generally +/- 5 KHz.  The K3/K3S DSP and audio brick wall
filters will limit the highest audio frequency to around 4.5 KHz
but you can always use the DSP to further reduce the highest
audio frequency to 2.8 - 3 KHz if needed to limit QRM.

You can further reduce QRM by using the 2.7 or 2.8 KHz filter
in synch mode to demodulate either just the upper sideband or
lower sideband if one sideband is being clobbered by QRM.

Hi all,

Does Elecraft sell a longer version of the standard cable? I need about 3
more feet. As an alternative, can 2 of these cables be used in series to
provide the extra length without creating any timing issues for the KPA1500?

Thanks & 73,

Just one more case of "no good deed goes unpunished!" 


The "punishment" was the innocent misuse of an infrequently used 
phrase when the writer clearly intended to praise Eric for far 
exceeding customer expectations. 


Not to belabor the point, but "beyond the pale" means exactly the 
opposite of what the writer intended: 


"Outside the bounds of morality, acceptable behavior or good judgement"

The problem is due to people using words without understanding heir meaning. 
There should be no confusion between semiannual and biannual. semi means 
half, and bi is two.

If you want to really find out how messed up is the English language and the 
definitions of words, start solving cryptic crossword puzzles. Some words 
have three completely different sets of meanings.

You are so right. So many people seem to guess what words or phrases mean without bothering to determine what the rest of society agrees that they mean. Then they expect you to understand their personal interpretation. 

However, I?d add that it?s also useful to remember George Bernard Shaw and his ?two countries divided by a common language?. Try suggesting a ?fag break? to workers in the USA (as I did one coffee time in the 1970?s).

Message-ID: <BC41D668-550B-4B46-95FF-94B240914290@law.du.edu>

It's from an earlier meaning of the word pale, which meant a specific region or area within a defined boundary.  Hence the denotation of beyond the pale is "outside the boundary."  Another current use of the word's earlier meaning is the phrase "The Pale of Settlement," which meant and to historians still means a bounded region in Russia into which Russian Jews were herded and allowed to live, more or less, during the generation before the first World War.

I agree with Wayne that today the connotation is usually negative; and I also understood the user to mean it literally and so not negatively at all.

    "Beyond the pale" is an infrequently used idiomatic expression (at least in the U.S.), probably misunderstood by many. I believe it is used in a negative sense for the most part, but clearly that isn't what the writer meant. 
    
    Some English words have become completely useless in practice, like "semiannual" and "biannual," either of which can mean "twice a year" or "every other year." In fact if you look up the definition for one, you often see the other shown as a synonym.

It likely depends on which area of the US you are in.
I don't know about the current vernacular, but where I grew up in 
Central Eastern Ohio in the 1950s and 1960s, cigarettes were known as 
"fags", and a 'fag break' would be a perfectly acceptable expression.

I once heard a broadcast from KDKA in Pittsburg, PA where several 
language expressions that were unique to that area were cited.  The one 
that sticks in my mind is "chuckle" referring to a pothole in the road.
A lot depends on the context.  I remember my Grandmother referring to 
"Go dowm celler to do the wershing" on Mondays.

Even within the USA, there is a wide variety of local expressions like 
that.  When I first moved to NC, I did a 2nd take the first time I heard 
someone say they had to "carry their Mother to the doctor"!

The word that struck my attention is "solar" and the possibility of that
controller causing noise.  When you were connected to just the battery and
dummy load, was the battery disconnected from the solar system?  And, at
what level was the buzz relative to a full power carrier?

Every transmitter has some noise on its signal.  Specifications and FCC
rules in some cases call for a specific ratio.  I can't imagine a factory
reset solving a problem like this.  Be certain you have saved your
configuration first.  Solving issues like this is not magic, but sometimes a
mystery.

In addition to operating from a battery isolated from the solar system, 
I would recommend that you do a quick test - remove all cables from the 
K3S except the power cable and a coax to a dummy load.  Power down all 
power supplies in your station, including any desk lamps.
Go into Transmit by tapping the XMIT button.
Is the hum still present?  If not, then start connecting things to your 
K3S one at a time, doing the same test after each thing connected.

Of course, if the hum is present with nothing connected, contact 
support at elecraft.com - but I cannot imagine a hum with harmonics of 60 
Hz being induced if you take away all the 60 Hz operated sources in the 
area.

I think you may have hit on it, Bill. Say it's a pulse-regulated 
controller on the battery is on the soft side.? BTW -- most solar charge 
controllers put out a lot of RF noise. The only good pulsing 
controllers? I've found are the MPPT controllers made by Genasun.
https://sunforgellc.com/genasun/#gen_product_row

Another question to help diagnose the problem if it's the battery -- 
what's the DC voltage at the battery in RX mode?? In TX mode?? What does 
the K3 internal voltmeter read for RX and TX?

It especially depends on what part of the world you're in... 


Years ago Mmy wife Phyllis and I spent a weekend visiting Al G3FXB 
and his XYL Maud. I'll never forget Phyllis' astonishment when, after 
a long night of enjoyable conversation and when she was ready for 
bed, Al asked: 


When would you like me to knock you up tomorrow?

It likely depends on which area of the US you are in. 
I don't know about the current vernacular, but where I grew up in 
Central Eastern Ohio in the 1950s and 1960s, cigarettes were known as 
"fags", and a 'fag break' would be a perfectly acceptable expression. 

I once heard a broadcast from KDKA in Pittsburg, PA where several 
language expressions that were unique to that area were cited. The one 
that sticks in my mind is "chuckle" referring to a pothole in the road. 
A lot depends on the context. I remember my Grandmother referring to 
"Go dowm celler to do the wershing" on Mondays. 

Even within the USA, there is a wide variety of local expressions like 
that. When I first moved to NC, I did a 2nd take the first time I heard 
someone say they had to "carry their Mother to the doctor"!

Grant: thanks for the link to the install manual. WOW!? I don't see that in my future - too many places for errors. My K3 is not broken and I don't want to break it. Thanks again.

Of course, I could always sent the K3 out and have all the updates made and the DVR installed. But, all I operate on is 75 meters these days and really see no need for the updates. Again, the K3 is working wonderful.

I had this same problem years ago before purchasing my first K3. 
It turned out to magnetic field coupling between my HyGain 
T2X control box and an audio transformer in the transceiver. 


As Don suggested, be sure all power supplies including computers, 
UPSs and lamps are turned off during the test. 


If this doesn't work, take to K3S to a friends QTH and repeat the test

In addition to operating from a battery isolated from the solar system, 
I would recommend that you do a quick test - remove all cables from the 
K3S except the power cable and a coax to a dummy load. Power down all 
power supplies in your station, including any desk lamps. 
Go into Transmit by tapping the XMIT button. 
Is the hum still present? If not, then start connecting things to your 
K3S one at a time, doing the same test after each thing connected. 

Of course, if the hum is present with nothing connected, contact 
support at elecraft.com - but I cannot imagine a hum with harmonics of 60 
Hz being induced if you take away all the 60 Hz operated sources in the 
area.

That makes sense too. The transformers are unshielded, so are sitting 
ducks for strong nearby magnetic fields.? K6XX ran into this early on 
running RTTY from a big amp PSU very close to a K3. The coupling was so 
strong that it went into regeneration!

I did in fact wonder the same thing myself-- whether the solar controller
could be injecting some noise or just making some noise, so when I did the
battery test, I disconnected the battery from the controller and ran
directly from the battery to the rig.

I couldn't tell you a dB level of the buzz without having some more
accurate equipment to measure it, but it's very noticeable relative to my
voice when testing.  It was enough to make me think I had either RF
feedback or a ground loop giving me grief.

There could be something to be learned from the predominant frequencies
present in the buzz... they're more or less 120Hz apart, but they start at
a weird place-- 350 isn't a multiple of 60 or 120, but that particular spur
and the 470 and 830 Hz spurs are all pretty exact, though of course it's
not impossible that there's some FFT error in determining those frequencies
and they're actually 360, 480, and 840.

Curious, though, is that running on a battery, there's nothing to inject a
60Hz or 120Hz noise directly, especially not once I disconnected the rig
ground from the ground rod outside.  Which makes me wonder if the buzz is
just something in the house that's mixing with the carrier and
re-radiating.  For my next trick, this weekend I think I'll take everything
outside on a picnic table, away from house wiring, etc., and see if that
changes anything, or I might start with just the receiver outdoors and away
from house wiring, and then move on to both if needed.

My desk in this case sits adjacent a wall, and there's only a shower on the
other side of that wall.  I did turn off everything in the vicinity of the
desk and all the lights in the room (I've in fact heard a very similar hum
from the switching power supply for my mixer, and my first thought was it
was this that was being picked up), but I didn't turn off the computer on
the other side of the room.  In this case it will be easier to move the rig
outdoors with a battery than it will be to turn that computer off for the
moment.  It would have to be an impressively/obnoxiously strong magnetic
field from that side of the room to influence the transformers inside the
rig 8 feet away, but it's worth trying and simple enough to rule it out.

Flat, except I turned the first one down a few notches, which doesn't
really do much in my case because both the microphone and mixer that I use
(when they're actually connected) roll off below 150 and 80 Hz
respectively.  It had previously been suggested to me that rolling off low
frequency cruft is a good idea for AM and SSB.

Saying something doesn't make it true.  Belief in something doesn't make it
real. And if you have to lie to support a position, that position is not
worth supporting.

Yes but the EQ is in the digital path.  The EQ should be done there, preferably after the MIC input.   The AM BW does not attenuate the end like the SSB filter. 

I suggest -16 dB on the first 3 bands.

A pro audio colleague, Neil Muncy, now deceased, specialized in chasing 
down hum and buzz in home studios. One mechanism he ran into several 
times was "triplen" harmonic current on the incoming neutral or ground, 
and I worked with him on one of them. These harmonic currents are the 
result of distortion of the current waveform on power lines,which in 
turn is caused by current in anything with a capacitor input power 
supply drawing most of the current? at positive and negative peaks of 
the AC cycle. Most power lines outside our home are some form of 
3-phase, and in these systems, any harmonic divisible by 3 ADDS in the 
neutral rather than cancelling. The most prominent components are 180 
Hz, 360 Hz, 540 Hz, 720 Hz, and so on, and they are heard as "buzz" 
rather than hum.

Few of us have 3-phase power in our homes, but a power distribution 
system called "high leg Delta" or "wild leg" is VERY widely used in 
neighborhoods where the customers are a mix residential and light 
industrial.? This system is a Delta, but with one leg of the Delta 
center-tapped. The 3-phase customers are fed from the Delta, and 
single-phase customers from the center-tapped transformer. Single phase 
customers get phase-phase-neutral. The 3-phase customers get no neutral, 
but they generate lots of triplen harmonics that go to ground via the 
neutral bond in single-phase homes.? My home in the Santa Cruz 
Mountains, is fed single-phase power (120-0-120) by high-leg Delta.

Depending on lots of factors, that triplen current can get pretty large, 
and the magnetic field can couple into any magnetic loop, into any 
unshielded transformer, and into magnetic guitar pickups! That's where 
Neil came in.? How strong the pickup is depends on the routing of the 
neutral and ground wire carrying that triplen current. Another colleague 
working on the design of audio for a major TV studio in NYC found very 
high triplen currents in a vertical riser in the high rise building 
housing the studio, right next to the main mix console. MAJOR problem -- 
it got into almost all the gear and low level mic wiring in the room!

As to the accuracy of your FFT frequencies -- FFT's are computed in 
"bins" with their width dependent on the FFT parameters for any given 
measurement/display width. If bins are fairly wide, the frequencies 
you're reading could easily be triplen harmonics.

My standard recommendation for ham radio is to start with max cut of 50, 
100, and 200 Hz bands, 6 dB of cut of the 400 Hz band, and get signal 
reports. Do this in TXEQ. What sounds "right" will depend on your voice 
and your mic, so take this as a starting point.

A few more data points:

Changing TX EQ, including cutting the first 4 bands all the way down to -16
had no effect on the received signal.

Plugging in some headphones, turning the TX Monitor up all the way, I don't
detect the hum in the TX monitor signal either in TX test mode,
transmitting into a dummy load, or even transmitting into the antenna with
very low power.  If I turn up the Line In level, I just hear expected white
noise on the TX monitor.  So at least as far along the path as the TX
monitor, there's no hum or buzz introduced.

Switching the receiver (a KX3) to USB mode and using one leg of a
buddistick as an antenna so I can walk around, the noise received around
the house and outside is around S4 when transmitting about 100mW into the
antenna, though it varies some as I walk around.

I do have a set of power lines running through my back yard, and where I
live in San Mateo, you're always near somebody's wiring for something,
unfortunately... my neighbor's south wall is possibly as far as 8 feet away
from my north wall, etc.

It looks like two phases running along the top, then a transformer to two
phases and a neutral along the bottom, to which people's houses are
connected.

We also have underground utilities on our street, including a big green
transformer that sits in the corner of our front lawn.

I think the next test will be to take the K3S and the KX3 some distance
away from all of these things and see if the hum goes away, and if it does,
then figure out what thing the K3S needs to get away from in particular.
If it's the powerlines in my back yard or the transformer in my front yard,
then that'll be a difficult problem.

Sorry for the additional email, but this is particularly interesting: it
occurred to me that I'd never tried the reverse setup, so I put the KX3 in
transmit mode and 0.1W on AM in another room, and set the K3S on receive.
And sure enough, the K3S immediately started picking up S40 of buzzing
noise.  However if I tune the K3S to an AM broadcast station or WWV, no
buzz. So either both the K3S and KX3 are being affected on transmit in the
same way (which seems implausible but not impossible), or possibly
something else is going on at my QTH.

On the P3, I definitely see the noise when the KX3 is transmitting from the
other room.

Now I wish I had a scope so I could see what the AM carrier generated by
the KX3 and K3S looks like so I could tell if this is something that's
happening inside the transmitter, or something that is happening because of
some outside influence mixing powerline noise with the AM carrier.  The
important thing to me is that the carrier I'm putting out there is clean...
if there's some local mixing that happens that means I can't listen to my
own transmission without a buzz, I can live with that.

One kind of curious thing is that there's also a superimposed "squeaky
wheel" sound at random intervals detectable when the KX3 is transmitting an
AM carrier, and not otherwise, and also not when listening to WWV or AM
broadcast, which vaguely seems to correlate with how windy it is at any
given moment.  Could all of this be a "rusty bolt" effect from something in
the vicinity?

Before I forget, thank you to everyone who has responded thusfar with ideas
and suggestions.  This one is a real head-scratcher, and I appreciate
everyone bouncing ideas around with me.

If the problem is in fact originating with power line neutral distortion,
what, if anything could I actually do about it, beyond what I've already
done in running on battery power?  I can't really move my 'shack' in this
case.

I did find the "squeaky wheel" at least.  It was the end of one of the
aluminum straps of an antenna mast chimney mount brushing against a copper
ground wire in the wind.  A pair of tin snips solved that problem.  This
bit was kind of fascinating-- if I held a copper wire against the aluminum
strap, and position the antenna of the KX3 nearby, I could receive some
broadcast AM station on the 51.123 MHz carrier I was transmitting from
inside the house (it's pretty close to a multiple of 810kHz, so if I had to
guess, it was likely KGO I was getting).

I also found the noise gets a hell of a lot louder near the back gutter of
the house (which runs parallel to the power lines that run through the back
yard), though this could just be because the antenna of my KX3 was coupling
to it.

Yet to be determined is whether the noise is a local thing only affecting
reception (e.g., some kind of passive intermod), or if in fact it becomes
part of the signal I'm sending up to the ionosphere.  To really figure that
one out, I probably will need to make an actual distant AM contact and ask
someone to tell me how it sounds... this may be no small feat with the way
the sun is behaving lately, but I'll keep trying.

Saying something doesn't make it true.  Belief in something doesn't make it
real. And if you have to lie to support a position, that position is not
worth supporting.

I wish to thank all the folks here who offered helpful comments on the
problem.  Yes, I did all the checking of ports and drivers and
connections -  I've been dealing with those sort of things for years so
I've been there, but with no resolution this time.  Neil did relate his
solution to the problem and I will respectfully continue with him
off-line as to the details.

Again, thanks for the assist.--

I'm confused, Nick. Under what conditions DO you hear the buzz? Antenna 
connected to the K3S?

I'm more confused.? When you have been listening to your signal and 
hearing the buzz, HOW were you listening to it?? Were you listening on 
the KX3??? If you transmit 5-10W into a dummy load you should be able to 
hear your signal in a KX3 sitting next to it with NO antenna.

Does the buzz only happen when you're listening on the KX3 and there's 
an antenna connected to the K3S?? That brings up the possibility of 
passive intermod.? We'll talk about that after we've gotten the symptoms 
straight.

No, ALL power supplies with cap input filter have harmonics. But the 
problem is FAR, FAR larger than equipment in the shack.

Nick -- what kind of mic do you use with your rig? Is it an electret or 
a dynamic?? Another way of asking -- do you have turn on bias to make it 
work? Does the? buzz get worse with the mic plugged in? Does turning up 
the mic gain make it louder?

Hi Nick, 


Since there are many unknowns and concerns about the EMI and 
magnetic environment at your home QTH, it might be revealing 
to repeat your basic tests (battery and dummy load) at a friend's 
QTH. Maybe you also have a friend who owns a K3 or K3S. 


Forget about resetting your transceiver. Your varied descriptions 
point to EMI or one (or more) strong magnetic fields as the source 
of your difficulties. 


How far is the "big green transformer" from your ham shack? 


Have you ever attempted to perform this type of troubleshooting 
in the past? Y our emails leave the impression that your approach 
isn't very methodical. A friend with troubleshooting experience 
could be of great help in getting you organized for a successful result.

Sorry for the additional email, but this is particularly interesting: it 
occurred to me that I'd never tried the reverse setup, so I put the KX3 in 
transmit mode and 0.1W on AM in another room, and set the K3S on receive. 
And sure enough, the K3S immediately started picking up S40 of buzzing 
noise. However if I tune the K3S to an AM broadcast station or WWV, no 
buzz. So either both the K3S and KX3 are being affected on transmit in the 
same way (which seems implausible but not impossible), or possibly 
something else is going on at my QTH. 

On the P3, I definitely see the noise when the KX3 is transmitting from the 
other room. 

Now I wish I had a scope so I could see what the AM carrier generated by 
the KX3 and K3S looks like so I could tell if this is something that's 
happening inside the transmitter, or something that is happening because of 
some outside influence mixing powerline noise with the AM carrier. The 
important thing to me is that the carrier I'm putting out there is clean... 
if there's some local mixing that happens that means I can't listen to my 
own transmission without a buzz, I can live with that. 

One kind of curious thing is that there's also a superimposed "squeaky 
wheel" sound at random intervals detectable when the KX3 is transmitting an 
AM carrier, and not otherwise, and also not when listening to WWV or AM 
broadcast, which vaguely seems to correlate with how windy it is at any 
given moment. Could all of this be a "rusty bolt" effect from something in 
the vicinity?

Yes, but that lack of methodical troubleshooting is the result of most 
hams being weak on the fundamentals of fields and passive IM, instead 
seeing problems in the light of RFI and mythical concepts like "ground 
loops."

The two causes I've come around to smelling in this problem are passive 
IM (which Frank reminded me of) and power-related fields. And Frank's 
advice is right on.

The problem is due to people using words without understanding heir meaning.
There should be no confusion between semiannual and biannual. semi means
half, and bi is two.

If you want to really find out how messed up is the English language and the
definitions of words, start solving cryptic crossword puzzles. Some words
have three completely different sets of meanings.

It appears some members would excuse an obvious mistake, because they 
concur with what they believe is intended to be a compliment.?? But how 
do we know for sure what the writer intended to convey?? After all, his 
words are, in fact, a slur.

Words, in general, often often have very specific meanings, as do many 
technical words in engineering and scientific prose.?? For some 
professions, e.g., novelists, lawyers, and advocates of all stripes,? 
words are the very tools of the trade.?? On this reflector, members 
frequently criticize others for misusing technical words when speaking 
about radios, yet they would excuse a serious error in other contexts, 
because they agree with the presumed sentiment.

Kudos to the critic who gently, and politely asked whether the writer 
truly intended the opposite of what he likely intended to say.? Shame on 
those who would misuse some words, while admonishing the misuse of 
technical words.

You can rationalize as you like - fact is, the original post is a slur, 
and we should not criticize the critic - who is, in fact, correct !

Message-ID: <CAH8gbkaffFUkwxKUexAfH-7MroAeLCBbukda3V1yaVs8OdO9Og@mail.gmail.com>

Working on my 2nd K2 (S/N 7869) and have run into a problem with the VCO
alignment. I'm getting a constant 8.37 V at R30  at 4.000 MHz.. I cannot
change it with the full range of L30. Correct type inductor is installed at
L30.  Dropping the VFO down to 3.500 doesn't change it either. I have gone
back through the archives and read just about every post concerning this
problem but nothing I have tried has made any difference. I have double
checked all correct parts placements and orientations, re-flowed all
connections in the quadrant of the board around the VCO section. T5 is
wound as per the manual (from the Toroid Guy) and installed correctly. I
have tried both spreading and compressing the turns on T5 with no change
either way.

Regarding the thermistor board,  I have 4.18 V on pin 5 of U6.

Test in the previous section were within specs:

4 MHz Oscillator Cal using CAL FCTR was 12099.61 and confirmed with an
external counter.
Range of the PLL reference oscillator: 12099.61 - 12086.01 = 13.59 kHz
VCO oscillator test: 8162.60 MHz

I'm about out of ideas at this point. What should I start checking next?

Thanks for any help!

John,

That high voltage is trying to reduce the capacity of the varactors.
Which means there is either too much capacity or too much inductance in 
the circuit.

Check the value of C72 first - it should be marked "271".  Then set the 
L30 slug to about mid-position and spread the red turns of T5 enough so 
the starting and ending turns are adjacent.  What is the voltage when 
tuned to 4000 kHz?  Measure the frequency at TP1 - it should be near 
8913 kHz.

Then change to 40 meters - 7100 kHz - What is the R30 voltage and what 
is the VFO frequency measured at TP1.

The answer to those questions will help in determining what to do next.

73,
Don W3FPR

I don't think that "collecting data" and "process of elimination" are
particularly ANTI-methodical either.  But the fact is that most people will
never encounter this kind of problem and don't spend their days practicing
how to troubleshoot it, so they seek advice from people who do have
experience.  Thus this email thread, which began with my thinking I'd
developed an audio fault in the rig and seeking advice, but successive
tests have pointed in other directions.

To answer Jim's earlier question, yes, it does appear that transmitting an
unmodulated AM carrier from the K3S into anything resembling an antenna
yields a buzz on the KX3 receiver (and vice-versa).  The buzz is NOT
audible when listening to the K3S's own TX monitor.

And to answer Frank's question, the PG&E transformer in our front yard for
the underground utilities is approximately 30 horizontal feet over and 6
vertical feet down from the station.  The distance to the utilities that
run through the back of our lot is approximately 60 feet.

I spent the morning reviewing (again) materials on grounding and bonding
over my morning coffee to see if there's something important I missed, and
I also found by repeating it that an earlier test I'd done had given me a
misleading/contradictory result-- transmitting into a dummy load
immediately adjacent the KX3 receiving it produces a nice, clean signal.  I
was misled before by the KX3 picking up a different buzz (probably off a
wall wart) in the shack when performing this test earlier.  (It also helped
in this case to put the KX3 into CW mode to detect the unmodulated AM
carrier.)

FWIW, this morning I also disconnected the bonding between the station's
ground rod and the house's utility power and also disconnected the DTV
antenna run into the house (which shares the same coax grounding/surge
protection bus outside, but of course could find another path to ground
over the coax shield via either one of the TV receivers).  Doing so
eliminated any *direct * connection with the utility power, as I'm still
running purely on battery power.  This had NO effect on the received buzz.

At this point I'm pretty sure this is an environmental issue and not a
problem with either rig, so it's probably not appropriate for me to
continue to pester the list about it.  Thank you again to everyone who
offered suggestions and advice.

But for posterity, and in case anyone comes along searching the list while
debugging a similar problem, here's a list of all the other things that I
tried to isolate the problem, none of which had any effect:

   - Complete disconnection of all other inputs and outputs on the K3S
   other than the antenna.
   - Turning off all nearby power supplies.
   - Setting the input to any other selection (front panel, rear panel,
   line in)
   - Setting the line input level to 0, verifying that front and rear panel
   gains were set to "low"
   - Running solely on battery power without the solar charge controller
   - TX EQ settings- cutting the low end completely
   - Taking the receiver outdoors, away from power supplies
   - Trying a different transmit antenna (ie, making sure I wasn't having
   problems with a damaged dipole having the house neutral wiring as one leg)
   - Temporarily disconnecting the station ground
   - Temporarily disconnecting the utility bonding from the station's
   ground rod
   - Reversing the direction: transmitting with the KX3 into a portable
   antenna and receiving with the K3S also produced a much more significant
   buzz

What DID yield some useful data:

   - Transmitting into a dummy load *while* turning off all nearby power
   supplies and lights with the KX3 immediately adjacent the dummy load: nice,
   pristine signal
   - Checking the TX monitor on the K3S: only white noise with the line
   input and the monitor output turned to maximum while transmitting.

What I have yet to do, and will require some more time and effort to
organize and implement:

   - Going portable or to another QTH to test again
   - Getting a signal report from a distant station to see if this is a
   local reception problem, or something actually getting into the transmitted
   signal.

OK. Try this test. Running from a battery, no connection to anything 
grounded, TX into an antenna and listen on the KX3 running on internal 
batteries, also not connected to anything grounded. Do you hear buzz? If 
not, walk around until you do. If you do, walk around until it's 
loudest. What this test is doing is probing for some source of passive 
intermod. It could be in your own home, or it could be somewhere else.

And try this test. Transmit into an antenna and have someone listen to 
your signal. I see that you're only 36 miles from me, so perhaps I could 
do that on 75M if you have a suitable antenna.

I haven't seen an answer for my question about DC voltage under RX and 
TX conditions.

What they are saying is that it is best to break things down into 
logical clear steps, isolating as much as possible to prove or eliminate 
cause and effect.? The issue are that some folks don't know enough to do 
this and some have issues trying to be logical; running in circles while 
others often seek the easy way(s) out. No slur is meant or intended, 
people have different abilities or we wouldn't need groups like this.

This is all best done while the XYL is at the spa or otherwise 
unavailable for a few hours.? ;-)

Here is one example for your situation:

A critical and valid test to find the source of your radio problem is to 
run the radio on battery (no solar, no other wiring including ground) 
into a dummy load (completely isolated from everything, including any 
metal table that might be in use) with the house mains (and any 
outbuildings) turned completely OFF.? Set up the test receiver in the 
same manner (nothing but different battery for power and another dummy 
load).

This is to determine if it's the radio or the home environment (no stray 
induction).? If everything is clean, it's probably not the radio but to 
make sure...

The second portion of that test would be to repeat on different bands or 
frequencies within the band to eliminate 'fundamental overload'? or 
unexpected mixing of the receiver (which should also be on a dummy load, 
proximity is likely enough to hear the signal).? Is it band related or 
single band, on one frequency only or all?? At only certain output power 
levels (bad internal amp?? A 100 watt K3 has a series of three amps)?? 
If the radio is clean, skip the next step.

The third step (if the problem still exists) is to provide physical 
isolation of the receiver (another room even if both are on dummy loads) 
to note any changes (overload or coupling is no longer likely).? If the 
problem remains, it's a radio issue (don't discount a receiver issue so 
you can confirm the issue with a second receiver).

Then based on these results, if it's all clean, (therefore not a radio 
issue so more testing is required to find the actual cause) one then 
determines a potential cause as you re-power the house (breaker by 
breaker).? In other words, when does it return?

In the best case, flipping only one breaker on, testing, turning that 
breaker off and moving to the next breaker; then bringing multiple 
breakers on in combinations (interaction of home devices?).? At which 
point/s does the issue return?? Single breaker means examine everything 
powered on that circuit, mixed breakers is much more of a challenge to 
find the cause.? Recall that house wiring often appears 'random' so it 
may be a challenge to find what each circuit powers.

If the problem doesn't return with turning on all the breakers, the 
search continues.

Note changes as you reconnect to the rest of the world (add antennas, 
control cables, etc) to your station.? Through more testing, at which 
point does the issue return?

Then reset all the clocks in the house as you ponder the results.

With an antenna connected, this series of tests also gives you a good 
baseline for RF noise reduction if the home generates noise (it's 
guaranteed that it will).

In your case, just for giggles, make SURE that ALL the tmp connectors in 
the K3(s) are properly connected as well (re-seat them) and re-tighten 
all screws and bolts as well (Murphy lives). While it's opened up, make 
sure no case paint is in the way of any bonding too, no corrosion, 
roaming parts etc. and look for obvious failures (disconnected wires, 
frays or pinched wire all without the smell of escaped smoke).

And lastly, a complete reset (groan) is an option, sometimes things are 
not what they show to be or are expected to be (stuck bits, EEPROM 
belches...).? Made when the radio is functioning correctly, you DO have 
a current backup of settings to use, no? If not, you manually make what 
changes are required (MANY of them, hence the groan) THEN make a backup.

Now if there is a need to call for further assistance (Elecraft help 
line, your Elmer or here), one has (dis)proven some of the possibilities 
to present the issue.

While others may disagree in this content, this is but one path to follow.

Subject: [Elecraft] K2 - Bar Graph Erratic - New symptoms
Message-ID: <CAAfqLSC8ouKizDfObVKQdZHa6KDXqtMBa4o2N5XpO42v9ss4mg@mail.gmail.com>

I posted several days ago about the bar graph (s meter & w meter) on my K2
was erratic.  I received suggestions suggesting changing the RF gain
control and re-doing the S meter calibration.  Today i did the following:

1. carefully monitored the audio from K2 as the RF gain control was rotated
and found it to be smooth and without dead spots etc.

2. checked the AGC threshold and found it to be 3.8 v.  in the CAL S LO
mode found the settings to be per the S-meter alignment procedure.

3. in the CAL S HI mode i could not get segments past the 2 left most ones
to eliminate.  Left adjustment as found

4. In the transmit mode only the 2 left most segments illuminate regardless
of the power setting.  Placing the Display in RF mode the output power
varies smoothly from 0.1 to well over 10 watts.  However, the bar graph
never illuminates more than the 2 left most segments.

5. this seems to suggest an issue with the front panel board associated
with the bar graph display.  Any suggestions on next steps, what to look
for on the board or other ideas?

Thanks in advance,

Robie - AJ4F

Hi Don,

Thanks for the quick response. I did check C72 again. It is a 271 value. I
then spread the red turns on T5 as far as I could. I'd say they cover about
90+% of the toroid. I put the L30 slug at mid-point of travel and measured
voltage at R30 and it is still right at 8.37 V.  While there I checked the
frequency at TP1 and it was 8247.90, which is considerably lower than the
8913 that you expected.

Next I went up to 7100 and measured the voltage at R30. Still right at 8.37
V, no change. Frequency at TP1 @ 7100 was 11558.11.

So, it appears that the frequency at 4000 is not within the expected range,
and likely not at 7100 as well. Hope this tells you something because I'm
stumped.
I've got some plans for this evening so I may not get back on it until
tomorrow afternoon, but if you've got any more things for me to try I will
do them then.

John, WB4GLJ

Subject: [Elecraft] KPA-1500 input too high
Message-ID: <00f601d4fd43$05b26300$11172900$@gmail.com>

Hi All,

 

KPA-1500 s/n 423

 

Operating 80 meter SSB running 20 watts drive with tuner engaged for about
1240 watts out PEP. Remote app shows maximum power handling of 1620 watts.

Out of nowhere I got an input power too high alarm @ 191 watts! The radio is
capable of 100 watts out max and verified is set to 20 watts.

 

Set tune power to 10 watts.

Meter in amp during standby reads 10 watts. 

Switch to operate and immediately get input power too high alarm @ 91 watts.

 

Switch to 20 meters (resonant antenna). No issue - 10 watts tune is
approximately 400 watts out with no error.

 

Any ideas?

 

Dave wo2x

John,

Both frequencies are too low.
You have either too much capacitance or too much inductance in the VFO.? 
Count the number of times the red wire goes through the center of the T5 
core - it should be 16.

Check relays K13, K14 and K15 for solder bridges.

Make sure the core of T5 is yellow.
You might have to try removing a turn from T5 if you can find no other 
cause - there have been a few K2s in the long past where the 
permeability if the T5 core was higher than expected, and removing 1 
turn from T5 corrected things - I have not seen that recently, but I do 
mention it 'just in case'.

If all else fails, you may have to "wind your way" through the relay 
connections for the VFO Range Select area using the Relay Table on the 
Schematic Key page as your guide for the paths through the relays.

What are you using to drive the KPA1500?

Connect the driving transceiver to an external wattmeter, and then to a 
dummy load.  Do a KeyDown in CW mode and see what the actual power 
output is shown on the external wattmeter.

My thinking is that your driving transceiver has lost its ability to 
control the power output.  Do the test with an external wattmeter and a 
dummy load rather than depending on the power indications from either 
the KPA1500 or the driving transceiver.  In other words, check each 
piece of gear one piece at a time.

Hi Don,

I?m sure you remember that my K2 kit (serial 7818) experienced the exact same issue. I went through all of your suggestions without any success.

My K2 is now in the hands of Elecraft Support. I?m hoping they will find a solution to my (and John?s) issue.
Just a FYI. Many thanks for all of your help!

Don, first thing I did. Radio is indeed sending 20 watts on 80 meters. Is a Flex 6600, not capable of 191 watts the amp said it was seeing.

The 3 watt, 3k Ohm resistor on the filter board is discolored and one side desoldered itself. This provides RF to the onboard frequency counter. This is the second time in three months that resistor has been an issue. Last time it was discolored and fell off the board (mounted upside down).

This time it appears to be more involved than just the 3 watt resistor.

What are you using to drive the KPA1500?

Connect the driving transceiver to an external wattmeter, and then to a dummy load.  Do a KeyDown in CW mode and see what the actual power output is shown on the external wattmeter.

My thinking is that your driving transceiver has lost its ability to control the power output.  Do the test with an external wattmeter and a dummy load rather than depending on the power indications from either the KPA1500 or the driving transceiver.  In other words, check each piece of gear one piece at a time.

The input too high only happens into a non-resonant load (tuner in circuit).
Also noticed on 20 now when tuner is in operate there is a 3 dB drop in
noise floor.

This is the second time the 3 watt resistor has desoldered itself from the
board and both times the resistor is discolored.

Only one RF path from radios through switching into amp input. Amp output
feeds a 1x4 antenna switch. No other radios transmitting in near proximity.

Definitely something failed on filter board.

Hi Nick, 


You've done a good job organizing your tests and test results. 


One more question: how far is your transmitting antenna from 
your ham shack and other nearby homes? 


Very telling is this comment at the end of your email: 
"Transmitting into a dummy load *while* turning off all nearby power 
supplies and lights with the KX3 immediately adjacent the dummy load: nice, 
pristine signal" 


That certainly points to EMC issues in your environment. When you're 
ready for additional tests, first go back to your pristine signal case. 
Then -- one by one -- turn additional radio accessories and household 
on and reconnect them. Repeat your test each time you change 
something. 


I strongly suspect that you have a common EMI condition in your 
ham shack, probably elsewhere in your home and possibly in adjacent 
homes known as "RF FLOODING." 


What the heck is RF Flooding? When a strong RF signal enters a 
non-linear device (semiconductors most commonly, but also ferrites 
near saturation) that also carries other signals (most commonly AC 
power, but also computer related signals such as Ethernet), the 
non-linear device will mix the two signals together and reradiate 
them (including harmonics of the RF signal) on the wires connected 
to the non-linear device. 


Multi-operator and SO2R operator contest stations have experienced 
RF Flooding interference for decades, but the problem has become 
much worse as semiconductor devices have proliferated. Switching 
power supplies are among the worst offenders, especially wall-warts. 


If you have a RF flooding problem it will be especially apparent on 
the second and third harmonic of your transmitted signal. On the 
harmonic frequencies the buzz sidebands may be stronger than the 
transmitted harmonic. 


So what to do about it? If you don't intend to operate multi-operator 
or SO2R contests from your QTH, there's no reason to fix the problem 
at all. The buzz sidebands probably don't radiate more than a few 
hundred feet from your QTH. In that case its simply been an EMC 
learning experience about the consequences of introducing a strong 
RF field into a houseful of electronics.

Subject: Re: [Elecraft] K3S Audio buzz on transmit, especially AM 

I don't think that "collecting data" and "process of elimination" are 
particularly ANTI-methodical either. But the fact is that most people will 
never encounter this kind of problem and don't spend their days practicing 
how to troubleshoot it, so they seek advice from people who do have 
experience. Thus this email thread, which began with my thinking I'd 
developed an audio fault in the rig and seeking advice, but successive 
tests have pointed in other directions. 

To answer Jim's earlier question, yes, it does appear that transmitting an 
unmodulated AM carrier from the K3S into anything resembling an antenna 
yields a buzz on the KX3 receiver (and vice-versa). The buzz is NOT 
audible when listening to the K3S's own TX monitor. 

And to answer Frank's question, the PG&E transformer in our front yard for 
the underground utilities is approximately 30 horizontal feet over and 6 
vertical feet down from the station. The distance to the utilities that 
run through the back of our lot is approximately 60 feet. 

I spent the morning reviewing (again) materials on grounding and bonding 
over my morning coffee to see if there's something important I missed, and 
I also found by repeating it that an earlier test I'd done had given me a 
misleading/contradictory result-- transmitting into a dummy load 
immediately adjacent the KX3 receiving it produces a nice, clean signal. I 
was misled before by the KX3 picking up a different buzz (probably off a 
wall wart) in the shack when performing this test earlier. (It also helped 
in this case to put the KX3 into CW mode to detect the unmodulated AM 
carrier.) 

FWIW, this morning I also disconnected the bonding between the station's 
ground rod and the house's utility power and also disconnected the DTV 
antenna run into the house (which shares the same coax grounding/surge 
protection bus outside, but of course could find another path to ground 
over the coax shield via either one of the TV receivers). Doing so 
eliminated any *direct * connection with the utility power, as I'm still 
running purely on battery power. This had NO effect on the received buzz. 

At this point I'm pretty sure this is an environmental issue and not a 
problem with either rig, so it's probably not appropriate for me to 
continue to pester the list about it. Thank you again to everyone who 
offered suggestions and advice. 

But for posterity, and in case anyone comes along searching the list while 
debugging a similar problem, here's a list of all the other things that I 
tried to isolate the problem, none of which had any effect: 

- Complete disconnection of all other inputs and outputs on the K3S 
other than the antenna. 
- Turning off all nearby power supplies. 
- Setting the input to any other selection (front panel, rear panel, 
line in) 
- Setting the line input level to 0, verifying that front and rear panel 
gains were set to "low" 
- Running solely on battery power without the solar charge controller 
- TX EQ settings- cutting the low end completely 
- Taking the receiver outdoors, away from power supplies 
- Trying a different transmit antenna (ie, making sure I wasn't having 
problems with a damaged dipole having the house neutral wiring as one leg) 
- Temporarily disconnecting the station ground 
- Temporarily disconnecting the utility bonding from the station's 
ground rod 
- Reversing the direction: transmitting with the KX3 into a portable 
antenna and receiving with the K3S also produced a much more significant 
buzz 

What DID yield some useful data: 

- Transmitting into a dummy load *while* turning off all nearby power 
supplies and lights with the KX3 immediately adjacent the dummy load: nice, 
pristine signal 
- Checking the TX monitor on the K3S: only white noise with the line 
input and the monitor output turned to maximum while transmitting. 

What I have yet to do, and will require some more time and effort to 
organize and implement: 

- Going portable or to another QTH to test again 
- Getting a signal report from a distant station to see if this is a 
local reception problem, or something actually getting into the transmitted 
signal.

I can wait until tomorrow. Won?t bother them on Sunday. 

The symptom this time is different than last. Last time was amp acting like tuner not tuned. This time showing excessive input power even though actual power is fine. 

Let?s see what happens.

They are going to want to know what is going on with the input power. The burned resistor (twice!) is a very good indication that there is indeed too much power flowing into the KPA?s front end at times. It is quite possible for any transmitter to put out more power than spec at times, especially if it is not properly calibrated.
There are many rigs that as-designed have a bad tendency to overshoot drastically on key-down, then settle to the power they are supposed to be putting out. An analog wattmeter will not be fast enough to show the problem, but the amplifier?s input definitely sees it.

You need to get them to fix the KPA?s input circuit, but you should also investigate your transceiver to find out why it is overshooting at times. Perhaps it is in need of a fresh calibration or something else might be going on.

Hi Jack,

No indication suggests the radio is putting out excessive power. To prove the point I used two different radios (Flex 6600 and Anan 7000dle. Anan has PA power calibrated.)

Flex Power Genius XL has lightning fast protection and never shows spikes. Array Solutions Power Master II does not show spikes. It is NOT a spike issue but rather the amp thinks input power is excessive. It thinks 10 watts is 79 and 21 watts is 191.

Something is amiss when using the amp on 80 meters with tuner in circuit. Remote app says max power of 1620 but I run about 1250 max. All other bands are resonant. 

Another symptom is when going from standby to operate the noise floor drops 3 dB on bands where the tuner is bypassed.

The 3 watt resistor was added after initial design of Rev C filter board. It is in the circuit that feeds RF to the on board frequency counter. This is on the input side of the filter board. Maximum power I run on any band is 35 watts.

I am sure when the log file is reviewed it will show it is not spikes.

	battery voltages
Message-ID: <F606B426-9CA4-4723-B5F9-3B457FCDBB23@elecraft.com>

We have a new field test revision of KX2 / KX3 firmware ready that provides much more accurate ATU tuning when the transceiver is operated from low power supply / solar panel / battery voltages. 

For example, if you're using 8 NiMH or alkaline batteries, ATU tunes should now be reliable down to as low as 1.1 volts per cell (8.8 V as indicated by the rig's supply voltage display). On our lab radios we get good tunes with most loads even at 1 volt per cell (8.0 V). Results will vary somewhat due to component tolerances.

If you'd like to help us evaluate this new firmware, please email me directly. I'll send copies out to the first few dozen respondents. I'm sure we'll be doing a beta release next week. Everyone will then have access to it.

Did you build your K3?

If so, it?s no big deal. You do have to remove the from panel but it?s easy and trust me. The first time you installed the panel it was tricky. But after that it?s not hard at all. 

FYI: I bought a 10 Watt/ no ATU kit in August or 2009. I went into the thing every weekend till I had all the additions installed. Thought several times about putting a zipper on the top cover!  Don?t fret the disassembly/reassembly.

Subject: [Elecraft] KX3 Programming Passband and Passband offset ?
Message-ID: <DC076C34-F7DA-42C4-928C-D039E28E8BC4@newgas.net>

My KX3 is often operated remotely via a Raspberry Pi and VNC - mainly for digital working with JS8Call and WSJT-X. 
I?ve set up a set of programmed instructions that I run before each session to make sure that everything is set up correctly such as Data Mode A, Power Output, Microphone and Audio Settings.

I can see how to set the Bandwidth (Passband Tuning ) using the BW Command but  I want to have a defined bandwidth of 500 to 2500 Hz,   Is the right way to use 
 BW 20 ; IS 1500 ;    ?  Or is there a better way to adjust the PassBand offset ?

Hi John,

Would you elaborate as to why you want to have 500-2500hz as your audio
passband width?  I have my KX3 BW = 4.00 and run split mode with JS8Call
and WSJT-X.  That keeps my signal in the sweet spot and gives me a view to
other signals up past 2500Hz in case I want to try to work them.

regards,
Brian

Message-ID: <1825657390.2236897.1556466437203@mail.yahoo.com>

When the next KX3 software update is planned, will you please consider the following items:
1) The VFO B knob is in the B position at start up. When tapping RIT ( or XIT) the VFO B knob switch to OFS, as it should. However? the VFO B knob remains in the OFS position when tapping RIT again to switch RIT off. Rotating the VFO B knob does not seem to have any effect.The VFO B knob should return to the B position, when RIT is switched off. This would be easier than tapping the VFO B knob.
Also you may notice that if the KX3 is switched off while the RIT is on, then the RIT icon will be on but inactive, when the KX3 next time is switched on, because the VFO B knob correctly is in the B position.

2) AF/RF and Keyer/Mic can be adjusted while transmitting. The PBT I/II for some reason can not. My logging program can do it, but it would be more convenient to be able do it manually while transmitting.
Minor items maybe, but useful.
73 and thanksOZ7BQ Hans J?rgen (Joe)

Bottom end of the audio passband at 500 because all heartbeats etc. should normally be in 500-1000Hz range.  As to bandwidth, I am in a very noisy City environment in London.  My antenna is a 12m  end fed wire tied to the top of a wooden fence - and half of that length is shielded as it is between two houses.

A narrow bandwidth simply keeps the noise levels down, but will still capture virtually all the JS8Call traffic.  80m is unusable unless I can narrow the passband right down.

Rear panel mic input, electret mic. Mic+Lin on. VOM shows 8V across mic
element. Tried several mics.
VOX works on CW, not on SSB.   What am I missing? It used to work.
No biggie, I'm a CW guy but FD is coming up.

Ahh indeed.? Several hours at W7RN with a new router trying random 
things was less than productive.? A more structured, several step effort 
at home yielded the solution, which was primarily router pilot error.

TJ,
No callsign?
What rig are you using?  
Are you hearing the popping sound in the sidetone?
Definitely don't put a cap across the contacts.
You may need to diddle with your QSK settings.
Other users may be able to help you more if they know which rig.

Nice!! A Begali Intrepid,

All bugs will have contact bounce. K3 does not handle them well at all,
same for KX3/2. K2 is much more tolerant. Though normally for the dot side.

I fixed it with a home-brew debouncer:
https://www.kn5l.net/debounce555/

Others cam be found on the WWW. It was fun designing and building one.

Thank you for the additional details.  The commands you wrote about in this
thread should give you what you want.  Have you had a chance to try them
out yet to confirm?  I haven't tried myself, just read the programmer's ref
guide (E19) and drew it out on a piece of paper so I could see the
bandwidths and how they shift.  I always struggle with which way to shift.
Even wsjtx split mode gets me second guessing the direction of the shift.
Luckily the app knows what to do :-).

Is your motivation for reducing the noise above 2.5Khz due to unwanted AGC
action from these strong signals?  We can take this part of the
conversation off-list if you'd like.

regards,
Brian

I have tried all kinds of debouncing circuits, but the one that has 
always worked best is simply a 12v reed relay with a 10uf capacitor 
across its coil -- not across the contacts!

I used an SPST reed relay I got at the now-defunct Radio Shack, but 
there are many such relays that are suitable. Reed relays are fast 
enough to follow the contact bounce of the bug, hence the 10uf across 
the coil.

This works fine with a 9v battery or from your usual 12v station PS.

So bias is obviously turned on. I'm guessing VOX Gain, Mic Gain.

Try putting the K3 into TX mode with the front panel button, talk, and 
set mic gain to get RF out, then stop TX and set VOX Gain (short push of 
Menu).

For max talk power, set TXEQ with the first three bands max cut, about 6 
dB cut of the 4th band, a few dB boost of the top two bands.

Another thought, Dick.

We need to set Line In gain and Mic Gain separately. To do that, we must 
be set for Line In to set Line In gain. Check the manual -- I don't 
recall if the knob is adjusting Mic Gain in the Mic + Line position or 
if we must change to Mic In to set it.

Components fail for a reason, which almost always is because they have been over-stressed. Component manufacturers spend a lot of time analyzing their devices to determine their stress points, failure modes and safe usage areas. When we design equipment, we look at this information to make sure the component will perform exactly the way we need it to perform for the lifetime of the design, and that we do not stress the component so as to make sure that it remains in the safe zone. This is done for each and every component in the design. In some cases, such as high availability systems (think telephone switches and other mission-critical devices) the work is required by the customer in contracts, in others it is done to reduce the failure opportunities and thus the need for repairs. The arena of six-sigma design was created to directly address component design and reduce opportunities for failure.

When approaching a failure of this sort, you have to ask why the component failed. It didn?t fail on its own, there was some stress that caused it to fail. Resistor stresses are very well known. When they fail with an over-heating indication (burn marks, etc), then the over-stress has to be questioned. You can bet that it comes from having too much drive into the equipment. At that point, you then need to ask where that drive came from, then start looking at everything in the overall system for the reason. You will most likely be surprised where it comes from. The fact that this has happened twice is an excellent indicator that it is somewhere in the system that has yet to be properly investigated. I would encourage you to better look into the components to find out just what is going on. To put it another way, I have reviewed enough KPA500 log files for this scenario to have an excellent feel for where these problems arise. It is never the amplifier.

Good luck with your station. I hope you find the issue without too much difficulty.

I agree the root cause needs to be identified but my point is in standby power always reads correct. In operate on 80 with tuner in circuit everything is ok also until the failure.

Once something failed the amp is now reporting incorrectly that there is excessive input power. Wheter output power somehow is being coupled back into the input detection circuit or a failure of the circuit misreporting input power is still to be determined.

I find it near impossible that a Flex 6600 can have a forward spike of 191 watts when output set to 22 watts and go undetected since the radio is new. I also find a totally different radio also shows forward power alarm of 188 watts when also set to 22 watts.

This is clearly a failure of the amplifier causing it to misreport input power when in operate. There is also the issue of excessive power flowing through th3 3k Ohm 3 watt resistor that feeds the onboard frequency counter. Not sure why this is happening as I do not overdrive the amp and log files back that up.

I think that the reactance of my 80 meter antenna (optimized G5RV) may be too much for the amp & tuner. The remote app sjows max power of 1620 watts and I run 1250 PEP.

Maybe I should dump the KPA1500 and stick with the Power Genius XL, which by the way is working perfectly with an HF Auto in place of the KPA1500. No power spikes seen on the amp, tuner, or Power Master II.

I do appreciate you suggesting to check everything (radio, antenna, etc). Makes sense but this is a straight up amp failure. 

Now to determine what conditions caused the failure.

P.S. - I kmow about Six Sigma, having worked 17 years for Motorola.

Component manufacturers spend a lot of time analyzing their devices to determine their stress points, failure modes and safe usage areas. When we design equipment, we look at this information to make sure the component will perform exactly the way we need it to perform for the lifetime of the design, and that we do not stress the component so as to make sure that it remains in the safe zone. This is done for each and every component in the design. In some cases, such as high availability systems (think telephone switches and other mission-critical devices) the work is required by the customer in contracts, in others it is done to reduce the failure opportunities and thus the need for repairs. The arena of six-sigma design was created to directly address component design and reduce opportunities for failure.

When they fail with an over-heating indication (burn marks, etc), then the over-stress has to be questioned. You can bet that it comes from having too much drive into the equipment. At that point, you then need to ask where that drive came from, then start looking at everything in the overall system for the reason. You will most likely be surprised where it comes from. The fact that this has happened twice is an excellent indicator that it is somewhere in the system that has yet to be properly investigated. I would encourage you to better look into the components to find out just what is going on. To put it another way, I have reviewed enough KPA500 log files for this scenario to have an excellent feel for where these problems arise. It is never the amplifier.

Don,

Finally got back to the K2 this afternoon. I have confirmed that T5 is on
the yellow core, with 16 turns through the center on the red and 4 turns on
the green. I mentioned earlier that I got all the toroids from the Toroid
Guy, so I felt confident that it was correctly wound. I checked all the
relay pins on K13, K14, and K15 and did not see any solder bridges on any
of them. Next, I pulled T5 and removed one turn and re-installed.
Unfortunately, nothing has changed. I'm still getting that same 8.37 V at
R30. Incidentally, I'm getting the 8.37 V on either side of R30. Is that
normal? I can also pull T5 and wind a new one with the parts that came with
the kit if you think that might help, but something tells me that the
problem lies elsewhere. I also thought about pulling C72 and replacing it
with another one, but unfortunately there was only one of that value in the
kit and I don't have anything like it it my parts stash. Any new thoughts?

de John, WB4GLJ

Hi all, I'm new to the list. Just turned on my K3 and noticed I have no power out on 20 meters. I have performed all the normal trouble shooting stuff. The transmitter is fine on all other bands and has normal 100w output on a Bird 43 and Bird dummy load. It makes no difference if the rig is in bypass or ATU. It flashes HI SWR. I also put it on one of my antennas on another band and the tuner performed as it should. I suspect the ATU has gone wacky but wanted to consult here just on the off chance I may have missed something. Any input would be appreciated before I take a deep dive into the tuner. Thanks in advance for any help.

Sounds like you might have inadvertently changed the antenna selection ? e.g., ANT 2 when your antenna is on ANT 1.

I am having an issue with the band data out from the K3s and K3S. Both 
have are basically new. The K3S was NEW in Aug 2018 and the K3s had the 
I/O board replaced at the same time. Both units have the same issue. 
They don't seem to be able to drive band data input of a couple of 
antenna switches. The one switch has a 1K input resistor. If I change 
them to a 100 ohm resistor, they work fine.

So my questions are:

Is this normal?Should the band data work on the newer gear?
What am I missing?
Can someone tell me what to do?

yes, I know about the 2.2K resistors, but should I need to?

What are the values of the pulp resistors on the decoders, and what voltage do they pull up to? If 12V, the yes, you really need to worry about the 2.2K resistors and that 1K series.
Even at 5V you may have to do so. Work the problem out on paper - simple ohms law. Then determine if the low voltage that is presented to the decoder chip inputs is actually a low to those devices.

There are ways to make it work, just need to figure out where things are to start with.

Was the KPA1500 tested at maximum output power and duty cycle with a loading condition that required drive power to be just below the level that would trip the "input power too high"  monitor?

Is it possible that certain loading conditions would require a drive power level high enough to overheat the input resistor?

Hi Andy

I am thinking the reactance the antenna presents to the tuner may have
something to do with it. Even though SWR shows about 3.7:1 it may well do
with causing the issue.
At 3.636 the capacitance is 719 and inductance is 2100.
The only band I need a tuner is 80 meters. All other bands are resonant (I
do not operate 160)

I've opened a service request on the web site as well as following up with a
detailed email to support along with operating conditions and log file.

The amp will need to visit home to get repaired and updated. Another KPA1500
user with s/n close to mine just got his back from repair and there were a
few updates done to his that are definitely not done to mine.

Message-ID: <580bd66a-c5fb-d21a-2375-4bdddd440ecb@comcast.net>

My K3S fails the 6m calibration with FW 5.67.?? The FW instructions 
state that *some* KPA3A may go into oscillation, but then states that 
all KPA3As should use the ATN6 setting for TXGN HP.? Mine will not 
complete the 50W calibration with ATN6 activated and after the failure I 
it will only make 50w.? I get a ERR TXGN.? Without ATN6 mine will make 
100w just fine.? Also my TXGN LP = 95 which is high based on other 
threads I have read.

All this being said my 6m operation appears fine if I do not use the 
ATN6.?? I done over the air tests and both TX and RX are good.

I am curious to hear if others are seeing this issue and what they have 
done to resolve it.

Message-ID: <29b90904-99bb-ff99-a668-34fb4b073299@socket.net>

There are a number of polyurethane-type foam post-hole fillers on the 
market (Sika, Rainbow, Secure Set, Poly-Set, Postloc,etc.).? I would 
appreciate a brief discussion (10 replies maximum) from knowledgeable 
construction people as to what might be best for the following application.

I'm wanting to anchor a 50-foot Max-Gain Systems MK-8-HD fiberglass 
push-up mast weighing 24 pounds which will support a 5-inch plastic 
center-insulator bearing 16-gauge open-wire feed-line and ~130 feet of 
16-gauge radiator wire.

The foam will surround a 3-inch o.d. Schedule-40 PVC pipe in a 3-foot 
deep hole.

I'm prepared to further stabilize the mast above ground with T-posts.

Product-knowledgeable replies only, please, especially from utility 
company personnel who anchor utility poles with this stuff.

Thanks Grant NQ5T, when I have finished this post I will proceed to go wipe off the egg on my face. I had gone thru all bands to be sure I had the correct antenna port selected but after Grants post I figured I had better check that again and found it to be incorrect. All is good now. What a bonehead move. Sri for using up the bandwidth. After 65 years on the air I should have known better. Anyways, thanks guys.

Sounds like you might have inadvertently changed the antenna selection ? e.g., ANT 2 when your antenna is on ANT 1.

Not to worry Jim. We have all done it.
When I was a novice circa 1969 or 70, I was helping my brother-in-law, WA9ZES trim his freshly made 40 meter dipole. We could not figure out why the SWR never changed. We made it long to begin with, but still expected the SWR to change. After many trips up on the roof on a very cold day he was sitting at the operating desk musing what was wrong and finally noticed he had the antenna switch switched to the wrong antenna. When he switched to the 40 meter dipole the SWR was 1.9:1 and he said good enough.
Now that is egg on your face.

Art,

The Y-BOX (v2.1 and later) converts any standard (economical) 15-pin M/F
DE-15 cable into the equivalent of a KPAK3AUX cable, plus it supports other
features not supported by the stock Elecraft cable, such as KPA500 /
KPA1500 remote power on/off via a K3 macro (DIGOUT1 to pin 8), and easy
insertion of a SteppIR tuning relay Interrupt into the 15-pin cable's
keying line (pin 10).  It does not work with VGA monitor cables (never used
those with any Elecraft product).

I offer 15-pin cables with the Y-BOX in both 2.5 ($10) and 5-ft lengths
($12).  Connect two M/F 5-ft cables together to get 10 ft.

More info at https://bit.ly/Y-BOX .

Good afternoon, Jim?

Do not be embarrassed. I?m a newly-minted operator and have all kinds of mistakes yet to be made. I can say that I have a lot of experience with computers and cannot tell you how many times the question ?is it plugged in?? should have been the first things I checked. I will not estimate the number of hours spent troubleshooting that particular problem.

In any event, problem solved and it was a very simple problem to solve.

I had gone thru all bands to be sure I had the correct antenna port selected but after Grants post I figured I had better check that again and found it to be incorrect. All is good now. What a bonehead move. Sri for using up the bandwidth. After 65 years on the air I should have known better. Anyways, thanks guys.

The transmitter is fine on all other bands and has normal 100w output on a Bird 43 and Bird dummy load. It makes no difference if the rig is in bypass or ATU. It flashes HI SWR. I also put it on one of my antennas on another band and the tuner performed as it should. I suspect the ATU has gone wacky but wanted to consult here just on the off chance I may have missed something. Any input would be appreciated before I take a deep dive into the tuner. Thanks in advance for any help.

My Denver home is HOA-limited and due to foil-backed insulation in every wall is effectively a Faraday cage.  I am looking into remoting by Internet over that 100 miles.  If I do that, I personally would be comfortable adding any new ones to the ones I got while sitting on the mountain.  But there is no way I would feel right about adding an ATNO I snagged if I rented a station on the Atlantic or Pacific coast for the occasion and remoted from Denver to there.  Is that a difference in kind, because I own one and don't own the other?  A difference in degree because one's 100 miles and the other is over 1,000?  How about if I had a summer place on Nantucket and I personally owned the equipment there, operating it remotely from Colorado?  A difference in kind, or a difference in degree?

But some hams compete against other hams and that is, generally speaking, to the good as well.  So what should the rules be?  The WAS rule, I believe, says within a 50 mile radius.  I am one QSL short of 5BWAS because NE on 10 from my side of the Continental Divide in CO has eluded me for more than a decade.  I could drive to the CO/NE state line with a KX3 in the car but that would be a rule violation, so I haven't.   Should there be a radius limit for DXCC as well?  Should remoting be a separate rule of some sort?

I have an Elecraft K3S with last software release.
I use it with  my Begali Intrepid and my Vibroplex Presentation mod. 1964.
Always, I make at least  5 qsos/day, at speed 15-22wpm
Same firmware release ago, I had problems with the Vibroplex Presentation, I
dont remember exactly the message on the K3s screen but it give an error
when manipulating the bug.
After setting better the Vibroplex Presentation, with better dots contact
regulation, as suggested by GM4GZQ "Adjusting your bug" article, the problem
has been solved.
Only with one of the last release of firmware the problem returned, but now,
with last 5.67 version, I have no problem with Vibroplex or Intrepid.
The Intrepid anyway have a lot less bounces on dots contact than the
Vibroplex.
The K3S doesnt like very much contact bounces, anyway if you reduce them
there are not problems at all.

A PVC mast 3' into the ground will easily break off - use 2" galvanized 
pipe and allow several feet above the grass level. This will allow you 
to connect the 50' mast to same. Best to make a swivel mount several 
feet off the grass level to allow for putting it up and down. You must 
guy this tower every 10 feet or it will do the dance in the wind. For a 
light weight installation that is well guyed you can use post setting 
mix. You should use a tube and make a mushroom at the bottom to keep 
frost heaving at bay.

Guying is very important - you will gain most of your wind resistance 
strength from it. It will not survive even modest winds without guying.

I do something similar with a 25' piece of 2" aluminum pipe fastened at 
the grass level to an 8' T-post driven in 4'. The tower is guyed at 12' 
and the top. Guys go to T-posts and are tied off above 4' to provide for 
easy mowing. T-posts must be the heavy cast types - rolled are just junk 
and will easily fold under any load.

My NVIS wire antennas (75 and 40 meters) have survived in excess of 70 
MPH winds with no problems at all. My system has been up for about 10 
years without any failures.

Just remember, 50' is about four times more of a problem than my 25'. 
Also, aluminum pipe, although more expensive, will be much more solid 
than any plastic tube.

Kent,

Suggest you read and perform the calculations in Calculating the Required
Mast Strength section of *ARRL Antenna Book.  *You will also want to search
NWS.gov web site for Maximum Recorded Wind Gust speed at weather reporting
stations nearest you.

The first thing to do with any amplifier failure is to try it with a dummy load. If the problem still occurs, you can rule out SWR or RF feedback problems. It doesn?t seem like any of the above if it occurs on all bands, but it?s easy and a good start to a systematic diagnosis.

In addition to contesting, I use it to call friends for a pre-setup sked. 
They often don't show-up on-time or can't make it.  I quit after five
minutes with no response.

During FD several years ago, I took over the 40m station after a nearby
lightning strike took out the primary K3.  The back-up had no DVR.  That was
the longest four hours of the event (not a contest)!

I have also used the DVR for Special Event Station operations when the rates
slow down.  I wouldn't be without a DVR in my K3's!

Bill: I use mine in DX pileups, as I tend to get enthusiastic and holler my call, which could become tedious to my wife. M1 has my call, M2 has ?thanks, you?re also 59?.  CW memories for M1 and M2 have similar function.   

I tend to use M1 less often and M2 sooner since the arrival of my KPA1500.

Good to meet you in Visalia!

I use AUDACITY which is a free software, record my own messages, set it 
to? play a loop and let it feed the radio.? It can be used for most all 
modes, SSB and CW.???? I have several pre-recorded messages which I can 
easily choose.?? All that is needed is the free software, and a single 
USB cable between the computer and my K3S. Set the input to MIC + LIN 
and turn on the VOX.? A few level tweaks and one is off and running.

Hi Ed,

Please email support at elecrat.com and they will dig into it immediately to help 
you resolve the problem.

If you can use the KPA1500 utility to download the 1500's config file and attach 
it to that email that will also be helpful.? (They can walk you through that 
procedure if needed.) that file includes both the amps full configuration and 
its detailed fault log.)

73,
Eric

Hi Vic, thanks.

That's the first thing I tried, should have included my checks in the 
first message.? Here is what I've done so far.

Put a dummy load on the antenna 1 port

Confirmed that the amp was on antenna port one

Checked the SWR between the K3 and the amp 1.1 without the K3 tuner

Re-seated all the cables on the KPA1500 rear panel

Tried the amp again and it works.? I have no idea what cable fixed the 
problem.? I am using a back to back cable between the K3 and the KPA1500 
AUX ports but it's been installed for months and I've experienced no 
problems.? We'll find out in tomorrow's CWT.? I think I'll run the amp 
at 900 watts until I gain confidence.

WOW! WHAT A RELIEF!

Ed

Hello,

Does your K2 need repair? Tuneup?
Want to sell it, but it needs some attention before offering it for sale? 

In addition to tuning your rig, I can also rescue a building project you might have started some time ago.

See what my clients have said about my construction and service work at 
http://www.eham.net/reviews/detail/6768

John,

Where did the? TP1? frequency go after you removed a turn?

It is possible that the VFO frequency is not getting back to U4 pin 4 -- 
the signal goes from U3 pin 6 thru C62 and then to U4.

Did we verify that U6 pin 5 is near 4 volts?? What is the voltage at U4 
pin 13?

Sorry to go over things, but I just returned from a few days away and my 
memory is not yet focused.

Great, there is nothing that is more fun than an intermittent problem!
But there could have been dirt on one of the pins of the cables, and it 
may never happen again.
Maybe Elecraft engineers can give you some hints.
See you in the CWTs tomorrow!

Hi Don,

No problem on the delay. OK, after removing 1 turn from T5, the freq. at
TP1 (at 4000) is now 8535.14, so it did come up from the previous value,
but clearly not enough. I have 4.19 V on pin 5 of U6 and I have 4.21 V on
pin 13 of U4.

I wasn't sure of your schedule so I also put in a support request to
Elecraft but have not received a reply as of yet. Hopefully between your
help and their help I can get this resolved.

 My KPA 500 has been running ok for several years on 120 Volts. Today I turned it off on the back , unplugged it and opened the top because I thought I might need to change the voltage tap. I did not need to change it. I replaced the top cover, plugged it in and turned it on at the back. All ok, but when I turned it on with the front panel button the HV reads .1 in standby. If I tap OPER it shows a hard fault and "270V error" .The Manual says this is a 270V supply failure and to recycle the mains power KPA 500 after it is corrected. I tried recycling the power but still faults. I don't have any 270V power from the mains, if I did it would be 240ish, not 270. The fuse block on the back is set to 115V.Any advice would be welcome.Mike, WM5DX.

The 270 V fault refers to the voltage that is used to bias the pin diodes in the T/R switch.   That voltage is derived from the same transformer tap as produces the nominal 60 V supply.  When I built my KPA500 kit I measured the voltage and found it was much lower than 270.  Customer support told me that was normal and I have never seen a 270 volt fault.

I'd have no problem removing the top cover and holding the micro switch closed while I measured the actual voltage on the 270 V connector.  I can't suggest that you do that.  Perhaps a careful visual inspection of everything you touched when you had the cover off?

The pin diode bias supply is 270dc. That is what is failing. Has nothing to do with your mains.
Generally you should look at the last thing(s) you did before it failed. That is where you opened it up and did something. How did you determine that the HV was ok as is? Unplug anything...inadvertently...?
Take a look where you were inside. Something with the interlock micro switch?

BTW - the top cover safety interlock switch controls 60 V and 270 V supplies.   Is it adjusted properly so the top cover closes it?

I've found that? hams are notorious for plugging in a multi pin 
connector and not securing the connector to be tight with the provided 
thumb screws. ? The "I'll do it later, but I've got to get it on the air 
now" seems to always take precedence . ? ? The connectors will wiggle 
and back out, often leaving an intermittent connection.

Likewise with PL-259 connectors.? Finger tight is simply not good enough 
for a reliable RF connection.? I use a pair of 4" Channel lock pliers to 
snug the PL-259 connectors.?? And I solved many RFI issues for others 
just by tightening the PL-259's in the path.

That 270 volts you refer to is the? "270 VDC" from the power supply.?? 
Check to see the covers are on tight and aligned correctly such that the 
safety interlock is engaged as it should be.?? Make sure a wire is not 
holding the cover off and thus not seating correctly.

Subject: [Elecraft] Appears that VFO is not tracking in diversity.
Message-ID: <1556660461015-0.post@n2.nabble.com>

Have read the manual and the various postings here and can not find problem.

When I turn on Diversity the B VFO does not track, and stays at the same
freq. Know it was working 6 months ago. Is there an obvious setting that
could not be correct? KC dot is flashing, Diversity ON comes up and then
DIVERSITY flashes (sometimes).  Arrow is pointing  at A and SUB is on in
display. Both receivers are working as determined by adjusting RF and AF
Separately.  Can tell it is in diversity while listening to a QSO as one
seems louder in one ear and vs/vs. 
Any help appreciated.

The B VFO doesn?t do anything in diversity receive.  Both receivers are driven by the A synth.  B VFO is only used for a split transmit frequency if you want.



You are thinking of the VFO LINK mode where B follows A with a given split.

Subject: [Elecraft] Appears that VFO is not tracking in diversity.

Have read the manual and the various postings here and can not find problem.

When I turn on Diversity the B VFO does not track, and stays at the same
freq. Know it was working 6 months ago. Is there an obvious setting that
could not be correct? KC dot is flashing, Diversity ON comes up and then
DIVERSITY flashes (sometimes).  Arrow is pointing  at A and SUB is on in
display. Both receivers are working as determined by adjusting RF and AF
Separately.  Can tell it is in diversity while listening to a QSO as one
seems louder in one ear and vs/vs.
Any help appreciated.

I started using a corrosion-inhibiting lube on my PL-259s, and religiously
sealing them with Coax-Seal. I tighten them very tightly as well. Since I
started doing that, I have no odd failures or intermittent connections in
my feedlines.

A good approach for those PL-259 connectors outside or exposed to the 
weather.?? For those inside, that's a might bit aggressive. I just 
prefer to snug them tight, a bit more than hand tight, using some small 
channel lock pliers.

I don't know if you're talking about what I do, Bob, but I guess I should
have said that I do that with the outdoor connectors, where they might
encounter weather. Indoor connectors are just snugged down tight enough
that they don't wiggle loose, since I disconnect them whenever lightning is
in the area.
