Much quieter last night and VO1NA decoded fairly well, but no European 
signals decoded, despite good SNRs at W1VD. Later, VE7BDQ fired up and 
even had a post-local sunrise bounce that gave weak decodes.

Ran two e-probes to separate SDR-IQs at times to compare the SNRs. The 
ground-mounted probe did a bit better (median advantage 1 dB; average 
advantage a bit greater) than the elevated probe. Hope the forced 72 
character wraparound doesn't make the following text unreadable:


sdr-iq1, GPS-locked clock 
          sdr-iq2, internal XO clock
eprobe2 - 10' AGL 
          eprobe1 - 35' AGL             SNR diff (2-1)
