[Elecraft] KRC2 question

[Jack Brindle]

There is no “power off” indication sent to the Auxbus from the K3 or K4, so no, there isn’t a direct way for the KRC2 to know if the radio is off.
Having said that, my KRC2 is powered through a relay that is controlled by the K3’s +12V out jack. It is powered on with the K3 and likewise
powered off when the K3 is shut down. That causes the drivers to be shut down and all antennas disconnected.
