Seems to me that measuring ERP at LF is a bit of a
problem. On here I have read comments referring to a stations ERP by various
operators : 'Estimate', 'Guess', 'Approx.', 'Reckon I'm fairly close
to...', 'Approaching' etc. Nobody REALLY knows exactly! Even Mike's book, 'LF
Today - A guide to success on 136kHz', refers to certain 'estimates' having to
be made. The last sentence on the bottom of p81 just about sums it
up.
I don't know what the answer is, but it is clear
that ERP at LF is far more complex than at VHF/UHF etc. where 'full size'
antennas are generally used.
