Others are asking for that to be switchable back and forth 
between the
two *dynamically*.  This involves both IF's and allows for 
signals in
the IF of one RX to be heard in the other.  This would a 
switch with
100 dB isolation.  It would be an expensive option, plus 
some
significant new code.  Don't think this complexity is 
commercially
feasibility.>>

I can get in that range in a 50 ohm system with a single 
relay at HF in a proper layout using the right style of 
relay.

I have not tried it with miniature relays, but I see no 
reason why it could not be done. It would probably take 
three $2 SPDT relays the size of a sixteen pin DIP package.
