No output in DATA A

[Julian, G4ILO]

There were a couple of posts about this a few days ago but they didn't seem to provoke much comment. Yesterday I switched on and tried to call someone and there was no output. The TX sound level from the speaker (MON was set to about 4) was barely audible. After examining various software settings and pushing a few buttons on the K3 the next transmission worked, so I put it down to operator error.

Just now I set up the K3 to do some WSPR on 40m and again there was no output. The audio tone was very weak though pushing METER and the level was showing 4-5 bars of ALC like it should. This time I remembered the earlier posts that suggested the problem disappeared when you changed band or mode. The K3 was already on 40m DATA A when I switched on so all I had touched apart from the POWER button was the VFO. So I changed mode to LSB and back to DATA and lo and behold on the next transmission cycle a signal was generated.

I think a bug has crept in during one of the recent updates. I'm running 3.47/2.41 at the moment.

Julian - I have had the same experience recently - I go to another band, transmit there, then come back and it generally fixes it. Unfortunately I can't replicate the problem, it strikes randomly - usually when there is a rare one.

Running 3.52/2.43 here

I have the problem only after using the TUNE-button, and a band or
mode change fix it (until next time).

Bad news: Going back to FW 3.44/2.38/1.04 does NOT remove the problem.

I have used 3.44 in contest without problems until I upgraded to 3.52
( I use the TUNE button when tuning my linear ).

Now back on 3.42 and the problem is gone.

When checking my calendar I can see that I only have used 3.44 in SSB
contest and therefore have not seen the problem before. :-)

I've found the cause of this. It will be fixed in the next beta release.
