[TenTec] Omni VI mic audio mystery

[Rob Atkinson, K5UJ]

Here's an interesting thing that happened over the weekend with my Omni VI:

I ragchewed with my regular roundtable on 75 meters Saturday night on my 
Omni.  All was well.  I was trying out a new transmatch in the feedline.  No 
problems with it.  Sunday morning I put the old transmatch in the feedline & 
turned on the Omni VI & set it up to check into a net on 20 m. phone & tuned 
the matching network to the net frequency with a swr analyzer.  At net time, 
mic keys radio but no USB output.  Turn on processor and switch multimeter 
over to processor & speak into mic.  Nothing on the meter.  Bad mic?  (Mic 
is a Heil goldline.)  Net has been going on for 10 minutes so give up on 
Omni & switch over to Corsair II and hook Heil up to it.  Mic and Corsair 
work fine; check into net etc.  After net decide to mess with Omni some 
more; hook mic back to it.  Now Omni works fine.  Weird eh?  Temperature in 
shack about 60 deg. F.  I doubt if the xmatch & temperature matter but I 
didn't want to leave anything out.
