K3 vs. KX3 with wsjt-x

I have noticed an significant difference between the way my K3
and KX3 work with wsjt-x. On the K3, the "Halt Tx" button
immediately stops transmission on the radio. With the KX3, the
radio remains in transmit mode, although the computer has
stopped sending audio. I have to press the "XMIT" button on the
radio to get it back to receive mode. It is as if the CAT
command to take the radio out of transmit mode isn't being sent
or is not being processed by the radio.

Not that on both radios other actions which use the CAT
interface, like changing bands from the wsjt-x UI, work correctly.

The K3 has been upgraded to the internal sound card/RS232
interface from the K3S.

The KX3 is being used with a USB <--> RS232 cable and a home
brew audio interface using a mini-dongle USB sound "card".

The computer in both cases is a MacBook Pro.

Has anyone else experienced this issue?

Re: K3 vs. KX3 with wsjt-x

What is the setting of MIC BTN on the KX3?

Re: K3 vs. KX3 with wsjt-x

Turning the MIC BTN off fixed the problem. Now Halt Tx stops the KX3 as well.

Should MIC BIAS be off as well?

Sounds like you have more than one PTT control active. Check out your interface and VOX settings.

MIC BIAS should be OFF unless you are using a mic that requires it. Bias has NO other use.

Re: K3 vs. KX3 with wsjt-x

In reply to this post by Nr4c

Yes, use only method for PTT. Either CAT or VOX, but never both. I
prefer CAT as, for digital operation, I don't have to mess with the VOX
values for my normal SSB operation.

Re: K3 vs. KX3 with wsjt-x

In reply to this post by Nr4c

It is not disabled automatically in Data A mode. I have looked and if I
don’t set it purposefully it will remain at the last setting per band. I
have macros that I use to toggle between voice operation and digital
modes. I set the mic bias and mic btn menu items accordingly.

Happy to proven wrong as I could then shorten my macros. But I have
experimented and what I have written is based on my observations of the
menu settings. Also, I found nothing in the KX3 operation manual to
indicate mic bias or btn are disabled on Data A mode.

Re: K3 vs. KX3 with wsjt-x

In reply to this post by K7RNA

I indeed had MIC BTN on, and turned it off. I the KX3 still
didn't go into receive when I pressed the "Halt Tx" button. (MIC
BIAS was already off.)

Another issue I didn't mention before seems to have gotten
worse. Sometimes pressing the "XMIT" button on the KX3 doesn't
take it out of transmit mode. When I press it it stays in
transmit. Press it again and it still is in transmit. It finally
goes into receive when wsjt-x gets to its receive phase.

I am still having problems developing a mental model of what is
actually happening here. Maybe I'll have to download the wsjt-s
source code and start reading code again. But that's what I
retired from years ago. :-)

Re: K3 vs. KX3 with wsjt-x

Make sure you are using only one PTT method. CAT or VOX but never both. I prefer CAT as any signal or any noise on the audio line will trip the VOX and thus hold it in transmit.

I have to press the "XMIT" button on the radio to get it back to receive mode. It is as if the CAT command to take the radio out of transmit mode isn't being sent or is not being processed by the radio.
