I have just tried 6 metre USB operation for the first time on my K3S and I notice that as soon as I key the transceiver (without speaking into the microphone), the transceiver draws a quiescent current of 18 Amps with a power meter indication of zero. When I speak into the microphone, the current reduces as the speech level increases and the power meter display seems to give a sensible indication.
If I reduce the power setting to below 10 Watts and then key the transceiver, the quiescent current drops to about 3 Amps. These standing currents seem very high; is this to be expected? Almost looks like the power amp is Class A biased? Can anybody please explain what is happening?
