28MHz WSPR

It's a long time since I did any WSPR activity at 28MHz, but recent conditions are now making this worthwhile, as operators return in much larger numbers to the band (although many could well do with forgetting what they did 5 years ago, and turn their power down from 5W!)

The clear thing with 10m WSPR is that, because signals are coming in via Es, which is inherently irregular in nature, the SNR pattern is extremely noisy when compared with lower bands; rapid deviations of ~20dB occur regularly in the following plot of my signal heard by DK6UG yesterday evening and into the morning today:

Meanwhile, a monster PMSE cloud is emerging through this morning.  It may well be another busy day on the higher bands!
