So true. If there is a signal its in receive mode or on that its in 
transmit mode, like RX+ or TX+ or PTT on the control connector that can 
run an external relay to put the receiver on a separate antenna. Not as 
fast as a PIN diode switch, but the PIN diode switch would be possible 
too. Might need a half amp at 12 volts for a good PIN diode switch. 
Probably can borrow circuits from an OMNI V or VI. Not much need to 
invent anything.
