[AMPS] abnormallly high plate current

[Lane Zeitler]

This all started when I went to calibrate the plate current meter. That is
when I discovered that the plate current was actually much higher that I
thought. The dummy load is not an issue since it has the same indications
using the antenna also with a 1.1:1 vswr.
