Dear All,
Today I rigged up and matched a simple, small, Marconi vertical on 136kH= z 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 US= B 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
