Re: No RF output on digital suddenly


 

Chances are, you are sending audio to the wrong USB speaker port.? This is digital and we are sending SSB.? If the radio isn't getting audio input, then you get zero power out - that is the nature of SSB.? You did some switching around with speakers, your driver?names may have changed.??

Ok, I'm hoping something is not wrong with the radio but that is looking less and less likely.

I have a Yaesu FT-991a that has been working FB for a few years. The other day I sat down at the shack to do some FT-8 and noticed that I wasn't getting any power out when transmitting.?

I've done system updates which includes kernel updates, obviously rebooting etc. to no effect.
I've also recently changed my desktop speakers from ones that used the on-board audio to providing their own soundcard?via USB-C.?

I can easily use pavucontrol to setup the audio devices and what applications they are attached to and am receiving audio from the radio fine. Even when sending audio to the radio the VU meter built into pavucontrol is showing audio.

I've reviewed the menu settings many times at this point using Dave's guide and can't find any problems.

I have done a full reset on the radio and set everything up from scratch.?

I can turn on the monitor (MONI) and I can hear audio when I use the front mic but not when transmitting digital modes (AND I don't know if that's expected to work).?

I've also tried using a Signalink USB which is configured to use the DATA port of the radio which had the exact same results. Receive audio works fine, no TX audio output.

To summarize...
1. Receive audio works using on-board sound card, TX audio does not.
2. Receive audio works using Signalink, TX audio does not.
3. CAT control works
4. PTT works

Any other ideas before I ship the radio to Yaesu??
