Hi Andy, LF,
I have been monitoring since seeing your WSPR signal at about 1215utc, the
signal was visible but no decodes, not visible now of course. Also the
grabber centred on 503.900KHz is running again at the moment.

Only got 8 decodes of your WSPR last night.

Hello Andy, LF,
I'm also monitoring for Andy's WSPR signal, by I think it's optimistic
to hope for reception at this range, in daylight, of a -6dBm ERP
transmission.
I will leave it running unitl 20:30z, when I'll QSY for Jay's overnight
tests.
Cheers,
John
