Yesterday at 2030 UTC I had a QSO on 80
metres with PA0HRT (over 190km) and PA0HRP (over 54km), the latter on his
motorboat.
After some 15 minutes the signals suddenly almost disappeared; we had just time
to agree to QSY to 160 m….
Dear Dick, LF Group,
There was a further X10 flare at almost
exactly that time – but it seems surprising to me that a flare could have
such an immediate effect after sunset – although perhaps the F layer
would still be in sunlight at 2045utc?
I have not looked at my overnight 137kHz
screen captures yet, but listening briefly last night, there seemed to be
remarkably little QRN on the band apart from some occasional loud crashes which
I took to be local thunder activity. There were also fewer and weaker spectral
lines around the 137.77kHz region compared to usual.
