With so little local and semi-local activity, I am getting no WSPR results so far this evening on the 630m band. This is more to do with low activity than the earth-electrode antenna system. Lack particularly of G activity is a serious issue: I shall have to abandon the band (with QRP ERP at least) unless more Gs and nearer continentals become active.
UPDATE 1830z: PA3ABK/2 (306km) was a strong -8dB S/N at 1814z. No-one else!
UPDATE 1915z: a few spots of me by G6AVK (78km). No-one else so far this evening.
UPDATE 1940z: F4DTL (431km) and DF2JP (461km) spotted.
