[K1] TX part sick

This post was updated on .

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 band module 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,

-----

Re: [K1] TX part sick

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.

K3 SignaLink & FT8 Question

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.

KPA 1500 CE Approval

In reply to this post by Don Wilhelm

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.

Re: [K1] TX part sick

In reply to this post by Don Wilhelm

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

Re: K3 SignaLink & FT8 Question

In reply to this post by Doug Turnbull

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.

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

Re: K3 SignaLink & FT8 Question

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.

Re: K3 SignaLink & FT8 Question

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.

Re: K3 SignaLink & FT8 Question

In reply to this post by Doug Turnbull

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).

Re: K3 SignaLink & FT8 Question

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.

K3 SignaLink & FT8 Question

In reply to this post by Bob McGraw - K4TAX

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.

Re: K3 SignaLink & FT8 Question

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.

Re: [K1] TX part sick

In reply to this post by Don Wilhelm

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

Re: [K1] TX part sick

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

Re: K3 SignaLink & FT8 Question

In reply to this post by Doug Turnbull

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.

Re: K3 SignaLink & FT8 Question

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.

Hi Doug,

Yes, we completed CE official lab testing a while back and the shipping amps now
have the CE label on them.

K1 manual revisions

In reply to this post by Don Wilhelm

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!
