DB20-G radio oddities

[UncleYoda]

[The cutesy title is a play on the brand name.]  Just had an unnerving occurrence where no sound was coming out of either earphones or the radio speaker (receive LED and signal meter did indicate it was receiving).  I tried all the relevant settings I could think of to no avail.  After giving it up for broken, I tried turning SUB back on and switched to B -- boom!, sound blaring out.  Switched back to A and sound there too.  And it worked with earphones too.  Doesn't make sense but I'm glad it started working again (no signals to test with right now).

The other odd thing I've noticed is the red TX LEDs will come on briefly at random times when I'm not touching the radio.  No pattern to it that I can discern so far.  And the mic is hanging up where the PTT button is not touching anything.

Might be a dodgy connection from the mic cable? those RJ-45 connectors aren't the strongest things in the world. If you jiggle the connector at the radio does it happen? I've noticed it do weird things if I disconnect or connect the mic or programming cable while the radio's on.

My At-779UV does the red blinking light thing too. I just jiggle the mic cord and it resolves. Haven't had the audio issue described.
