I should say so!
I suppose you are using the internal voltmeter in the VFO B position? For me
it reads 13.9V off-load (DMM reads 13.94V at the PSU output terminals). At
100W key down on 20m, rig draws about 18.5A, voltage drops to 13.5V. This is
using a Diamond GSV3000 PSU and the standard weedy K3 power cable, cropped
down to the shortest length possible to get from A to B, no more than a
couple of feet.
