Hi, Would it be possible on the KXPA100/KX3 combo (and K3*) to allow the ATU mode to be memorized per antenna? I have a small transmitting loop that is remotely tuned on ANT1 so wish to run with the ATU in bypass, but ANT2 is a EFHW which I like to have the tuner active (manual mode) for. I am

With respect to your first sentence, all I can say is, of course; is there anyone who thinks differently? In a signal generator, where source match is important, there will probably be an attenuator, or at UHF and above an isolator (terminated circulator), that dissipates returned power.
