[600MRG] WSPR reported Power?

[Warren]

Larry,

   On MF and especially LF there is a BIG difference between power out of 
the transmitter and effective radiated power due to low antenna efficiency.
 A station running 50 W into a big antenna might have higher actual radiated 
power than a station running 500W into an electrically small antenna.
