The KRC2 does not currently support two radios connected at the same  
time. In other words, if you want to connect a K2 and some other  
transceiver to determine which antenna is selected, the KRC2 will not  
handle this directly. It _will_ other rigs besides the K2, but only one  
at a time.

You could accomplish this with a pair of KRC2s, one controlled by each  
radio, using the outputs to control relays for antenna switching. It is  
relatively easy to connect the KRC2s and relays so that an antenna  
relay will not be energized if both radios select the same band.

I do not know of any automated antenna selector currently available  
that handles more than one rig at a time.

Your guess is correct. The KRC2 allows you to connect the K2 to one DB9  
port, and the KAT100 or other accessory to the second port. If you have  
a KAT100, the 'Y' cable that is built with that unit would connect to  
this port.

You are very welcome!
