7th new reporter on 137.5kHz WSPR

M0BMU copied my 137.5kHz QRP WSPR signal today giving me -19/-20dB S/N, which is quite a good report. Distance is 69kms. This is now the 7th unique station reporting my WSPR beacon. I'm still hoping for a report from outside of the UK soon, but suspect I'll have to increase the ERP beyond the current 20uW level to achieve this. The consistent signal report from Jim should allow me to calculate ERP based on field strength at a good distance. This will allow me to check the accuracy of my ERP measurements much nearer to home.
