This morning I have returned to 10m WSPR (100% TX, 500mW) and 6m WSPR (1W ERP 20% TX, 80% RX) hoping to see some Es. Late last night I realised I was on the wrong 6m frequency, so I would have missed any activity. This morning, all is correct! As yet, no WSPR spots here on 10m or 6m.
UPDATE 1655z: No spots here on 10m or 6m WSPR.
UPDATE 1905z: Now QRT on all bands. No WSPR spots all day! Might try again tomorrow.
