500kHz WSPR

Yesterday I fired up the 500kHz WSPR kit (2mW ERP from the loop antenna) for the first time in several months and was pleased with the reports and level of activity. Several people joined in the fun and some new stations are now monitoring and reporting on the band. I want to get my 137kHz WSPR kit sorted this week with around 25W RF and maybe 0.5mW ERP if I am lucky.
