Hello FM, I have a K3 with internal VHF transverter, assembled by factory. When I key (PTT) my K3 in USB on VHF with my amplifier my power supply is reading 45 amp even when I have no modulation in USB. When I do the same on HF, no meter reading only when I modulate in my microphone. Whats wrong, all info welcome. 73 - Rudi - ON7CL
