Re: LF: declared power on WSPR

[Roger Lapthorn <rogerlapthorn@gmail.com>]

Dimitris,

On LF and MF where the EIRP is very much lower than the RF power output from the transmitter, the accepted protocol is to specify EIRP in the WSPR database.

Incidentally, please will you change the links on your website to the G3XBM 472kHz transverter design? I have moved my pages and the 472kHz transverter page is now at https://sites.google.com/site/g3xbmqrp3/mflf/472khz_tvtr . The older page, although currently accessible, will not be public for much longer.

Today I also added my 137kHz TX transverter schematic at https://sites.google.com/site/g3xbmqrp3/mflf/137khz_tvrtr . This latter design is still a "work in progress" and this is the circuit as it is today.

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?
