[TenTec] Corsair II with separate receiver

[George E. Clark]

Because in certain conditions my Corsair II doesn't receive as well as my QRP rig, an ICOM 703 Plus, I'm interested in the possibility of operating the Corsair as transmitter and the ICOM as receiver, using a relay such as that described at http://www.ad5x.com/images/Articles/AntennaRelay.pdf .  

I have a few questions.  You may think of more questions, or have suggestions of other ways to work this problem without much outlay of cash.  

1) Which output on the Corsair II do I use to drive the relay, the one for an amplifier?  

2) Does that driver meet the specs for the relay described in the link above?

3) This might not be a relevant question for this list, but what on the 703 can I connect to the mute terminal on the switch to mute the receiver when I'm transmitting in SSB?  

Thoughts appreciated.
