[TenTec] Is The Eagle really soaring yet?.

[Rick - NJ0IP / DJ0IP]

If you don't run an amp, all you need is an RCA Phono Jack or BNC on the
back panel, a simple toggle switch on the back panel, and a pair of 1n4007
diodes.  Less than $10.  If amp, I would add in a reed relay to switch the
RX ant to ground during TX.

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.
