[Amps] Bird Element Calibration?

[Mark Hill]

Gary,

Indeed so!  When replying to the FCC, I believe the text goes something 
like:  "I dare not run QRP because I only have a 10k element for my Bird 
and if I don't get the pointer to top-scale, I cannot measure my power 
accurately!"

Regards.

Mark.
