Walter,

50 MHz TX constant 4 W carrier measures 13.53 V on DMM (outside the DC
power plug), 13.3 V on KX3 meter, 2.9 A on KX3 meter and 1.6 to 1 VSWR
on KX3 meter.  Microwave dummy load with BNC to N adapter.

I didn't measure all of this when the rig was new, so have no baseline
to know what is normal.  :-(

Thanks,

Drew
