As you will know, as well as 10m I have been on 6m WSPR most of the day (20% TX, 80% RX). Yet again here I have had no success at all on 6m. Not really sure why I try 6m.
Tonight I may return to 630m (472kHz) WSPR and try my luck with the 5mW ERP and earth-electrode "antenna". I have no idea how many others will be active.
