[Lowfer] watering hole

[Garry Hess]

Monitored around 185.3 kHz most of the night. Was pleased to see the 
upper WM come through immediately when I started around 0400Z. By 0515Z 
the lower WM was appearing in the ARGO QRSS30, slow waterfall, along 
with WMS and traces of UWL. At 0730Z WMS was strong enough to be seen in 
QRSS3 bandwidth.

At 0930Z shifted tuning to look for EMP. Haven't noticed that lowfer 
since Feb 9. Now I know why. Its frequency had shifted up to 185.590 
kHz, placing it just below a pair of strong carriers. That masked it 
from view with my usual coarse SpectraVue SDR-IQ display. Looking with 
Spectrum Laboratory and a 100 Hz spread, EMP was readily apparent and 
strong enough to decode CW aurally.

Spent the rest of the morning monitoring 518 kHz, where signals looked 
normal.
