Hi all,
Good copy of wd2xes from 0:00 to 5:30 UTC with a noticeable increase in the
S/N starting at 4:10 (2nd image)
Atmospheric noise is a few dB higher during the night and interestingly
decreases well before John's signal fades out.
I increased the SL brightness of the second image to show this noise
reduction.
Receiving conditions:
2 x 2 meter one-turn copper loop with high Z differential preamp
I/Q down converter, QSD based
Audigy 2 ZX notebook sound card
Spectrum Lab configured as SDR
73 Michel / f5wk JN18HP
