The need for a QRP output meter was felt when the homebrew SWR meters / RF ammeters in the shack proved useless for peaking the output of a homebrew 7MHz 5W solid state CW transmitter. For their pointers barely moved.
The homebrew RF ammeter was hence temporarily converted to a RF milliammeter as shown.

It was roughly calibrated to read around 100 RF milliamperes maximum. The CW transmitter was then easily adjusted.
A dedicated RF milliammeter is in the works.
