Just restarted WSPR beaconing on 137.5kHz using an ERP of around 50uW. Any reports of my QRPp beacon would be appreciated.

A report of -29dB S/N has been received already this morning from M0BMU (69km). He is very strong with me (+4dB S/N) as is G8IMR (-9dB S/N). The difference between M0BMU's reports of me and mine of Jim's suggests that my ERP calculation based on loop area and current is not far off, although my signal with Jim varies by at least 6dB over the day.
