Mike, J.B. and others; No I mis-typed that. I should have written 900
mW. It is fluctuating around 50 mA at 18V. I re-read that post several
times before sending it and didn't catch the typo. I don't think my
output efficiency is that great yet so the amount of RF going into the
antenna is less than the typical beacon.
