It's not all bad. When my Omni Vi opt. 3 had a transceive problem, I sent it
in. I had a few chats with the head tech describing the exact symptoms and
eventually was told that there was no problem at all, verified on two separate
benches. It was about $120 shipping out and back. No charge for the look-see.
Well, there WAS a problem. It was not transceiving on the same frequency,
just as I claimed.
I ended up sending it to a private repair guy, Wade, who used to participate
here. I've not seen him here in a long time. He found some parts in the chain
that needed replacing and that fixed it. You might consider getting in touch
with him.
