[Elecraft] K3 Receiver Protection

[Richard Thorne]

Larry,

The Microham mk2r+ will do exactly what you want to accomplish. If both 
rigs are on the same frequency, neither will transmit.

It is, however, an expensive solution.  I was lucky and picked up a used 
one at a very good price.

However, if both rigs accidentally wind up on the same band I run the risk of overloading the front end of the opposite rig and damaging the receiver (which I've done once...). Does anyone have a way of taking the band data information and disabling transmit capability on both rigs if they are on the same band? How are others using SO2R avoiding same band transmission and subsequent receiver damage? Anyone have any experience with the Array Solutions AS-RXFEP front end protector?
