JTDX will PTT with no power output or audio signal out

Juan TG9AJR

Hello has anyone experience an issue on FT8 using JTDX that will be working just fine and randomly will PTT the Flex (in my case a 6600) but will not send any audio or signal ?

It's been working fine for several weeks and even today all OK and suddenly will received and will PTT but not audio, sometime if I closed JTDX and open it again will work, others I have to close both JTDX and SmartSDR and others close both and power off all including the PC and might go back and work, well today I did all those scenarios to even reinstalled JTDX and will have CAT, will receive with PTT but no output...

I think I read something similar perhaps on the Facebook group but since it was working OK I thought it was all OK.

I can't say if this is related, but if I leave WSJT-X running for a while, I'm unsure how long, I have to close and restart it in order to transmit. Receive always works. So I'm in the habit of just restarting WSJT-X prior to trying to use it.

Same condition that you noted. PTT keys the radio, red LED, but no TX output.

In my case I basically only run JTDX and it does not seem to have a pattern of when or why it will not TX output (audio). It was working perfectly for a long time by now it didn't matter if I was transmitting a lot or just receiving for hours.

Today made a few QSOs OK then I notice it so I started the routine of trying it to solve it but so far none of that seemed to work as in the past...

Also if I just apply TUNE to the radio it will key with power output. So for sure it seems an audio issue.

OK, slightly different.

If I click the tune button in WSJT-X I get no power output when in the failure mode.
