Can't disagree with your statements, but Don has ZERO chance of getting any 
help from Icom.  The situation with the receive antenna input is well known 
among Icom 765 users who operate on 160.  KD9SV makes a nice little 
protection unit that can be used with the 765 and any other transceiver with 
a separate receive antenna input.  It grounds the receive input on the rig 
as well as disconnects the receive antenna during transmit (controlled by 
your PTT line).  Here's a link for those interested
http://www.radio-ware.com/products/fes.htm .  I've used one of these for a 
couple of years with no problems.  On the other hand, there are 765 users 
who ignore this potential problem completely and NEVER have had a problem. 
I hope Don gets his 765 fixed OK.

I don't think he's at fault either, and to me they owe him a repair job
or new rig IMHO. That equipment costs too much for something like that
to be thought of. If they knew it was this way, and did not have it in
the operations manual, that's just wrong and they owe him. There's
nobody that ought to have to read a schematic to see how one is before
they ever use it. That's BAD engineering practice if I ever seen it. If
I was Don, I'd call um up and raise he** until it was settled! Plus, I'm
glad he told it here so I know about Icoms, and whether I could trust
them now on what they make.
