[Elecraft] 160M Receive and Transmit Antenna Switching help

[Don Wilhelm]

Jim,

Since the KX3/KXPA100 combination has no RX ANT input, you will have to 
devise some kind of external T/R switching to connect the receiving loop 
during non-transmit times.
There is a PA Keying output from the KXPA100 that you could use to 
activate the T/R switch for transmit times.

If you use a relay, it must be fast enough to avoid hot-switching or you 
will be seeing the KXPA100 go into a fault condition.
