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.
