So far today, I have received loads of stations on 10m FT8 RX despite most of the antenna being on the ground awaiting the erection of the 8m dipole.
I notice these were not being uploaded to PSKreporter for some reason, so I shall restart WSJT-X in case this is at fault.
UPDATE 1521z: I did a resync to internet time and restarted WSJT-X: still no spots on PSKreporter.
UPDATE 1530z: All now seems well, with 10 stations recently uploaded. This will remain a puzzle. All uploads relate to stations spotted in the last 20 minutes.
