[TenTec] Orion/Orion II antenna isolation measurement

[Eric Scace K3NA]

   -40 dB isolation between antenna ports (including the RX antenna 
ports) has been typical with every ham transceiver that I've had a 
chance to measure to date.

   This needs to be taken into account when engineering a station, 
especially SO2R and multi-op contest stations where someone is listening 
while a transmitter is on the air.
