[BUG] TX-audio first screen has toggle. Not in XVFO-TX #65

Rel 0.32.20q

When transmitting on First screen I hear a toggle (approx 5 times per second) when I listen to my signal on other radio.

When I switch to second/XVFO-screen the audio is clean.

So there is an audio-improvement missing in first screen.

It's serial cross-talk. Hardware issue.

ErikS-web commented 8 months ago

The sound is already there when Q-dock is not running and REMOTE is ON on Radio. So it's initiated from the radio. It is also in the TX-audio on First Screen.

But why does this NOT occur in TX at XVFO-mode ? To me it seams that the radio is controlled in a different way at XVFO-TX.

It is, I specifically avoid serial communication during TX on XVFO for this exact reason (I have mentioned this before regarding a feature request that would require serial comms during TX). In normal mode it's out of my control. This is why I am designing my own audio interface card, in an attempt to reduce or eliminate this. But this is not a bug as it has nothing to do with the software, please change the title.

I might have been able to fix this, it will require a firmware update though. Next release.

ErikS-web commented 8 months ago

I was already thinking about something like that when you said it wasn't possible. It is clear when testing in Normal mode that the disturbance is initiated by the radio. This will then be an adjustment in the firmware to temper the communication from that side.

Very interesting . . .

Toggle is now every 2 seconds. Much better.

nicsure commented 8 months ago

I'll see if i can eliminate that as well.
