[Elecraft] K160Rx protection

[Don Wilhelm]

Hans,

The K2 RX ANT is injected at the same point after the T/R switch and 
before the Low Pass Filter, so any energy from the transmit antenna will 
not harm the K2 during transmit, although it may add to the RF level 
going into the LPF and be amplified by the KPA100.
