[Rick - WA4NVM]

Hi Ted,

I had the same problem, so never worked AO-27 and SO-50 years ago.  Then
I took your approach, hooked up my IC-706MkIIG as the receiver, problem
solved.  So then installed an antenna switch to move the 440 antenna between
the Kenwood and Icom.  I programmed 145.850 in a memory for transmit
and move the Icom vfo manually to track the downlink.  I never change the
transmit frequency and use the computer program for antenna position only.

Your mobile rig should work just fine on the downlink if you don't have a 
real
long coax run.  I might add, I do have a preamp at my antenna also, like 
Damon.
I use the TS-2000 "solo" for all other satellites.

73,

Rick WA4NVM
