Hi Bob (and Mark), My apologies, I think I may have taken us off the main topic. My experience and requirement was fairly simple and I needed something brainless to help make field day easy.
I have the acc2 cable from elecraft and then used a single phono cable to transmit the ptt event from the kx3 acc2 cable to the kpa500 PA Key input. Band switching was accomplished by the kpa500 directly. I quote from the kpa500 manual: *Automatic Band Switching: The KPA500 automatically measures the frequency of the RF drive * *and selects the proper band. The PA KEY input must be connected to the driving transmitter. * Again my apologies for taking us off topic as I don’t think I answered the spirit of Mark’s original post as I rely on the kpa500 to figure out what band I was transmitting via the Kx3 via the rf interconnect.
