So much for the theory then....

The signal level at G6ALB in the next village (3km although WSPR shows it as 0km) is some 10dB down on my loop antenna. Not sure if I got my sums wrong or there is some unexplained loss. The RX system at G6ALB is unchanged.

73s

Dear All,

Today I rigged up and matched a simple, small, Marconi vertical on 136kHz instead of the vertical loop. Based on measurements of antenna current and some reasonable assumptions of effective height, I now believe I have around 200uW ERP on the band - heck this is high power for me!

From now until late this evening I will run the WSPR beacon (136kHz USB dial) in the hope that a few more people will be able to copy the QRPp signal. Please have a go and let me have any reports.

73s and good luck
