Hi Dimitris,
unlike HF, antenna efficiencies at LF can
differ vastly from one site to another. So it makes much more sense to
state radiated power (ERP) than TX power.
Note that under current regulations,
ERP's beyond one watt are simply nonexistent, per definitionem ;-)

Subject: LF: declared power on WSPR
Hi group,
I was browsing the WSPR
database for MF and noticed that I am the only one declaring a 50 W power. My
TX power output is 50 W, however the radiate power is just a tiny fraction of
1 W. What is the protocol for WSPR? Advertise the Pout or the
EIRP?
