[Lowfer] watering hole last night in TN

And I just now noticed that the frequency markings on my screen captures
are about 2 Hz high. This is a strange anomaly that I have noticed before
with my Winradio SDR. Sometimes it will "jump" 2 Hz and then correct itself
later. This is not a slow change as the receiver warms up, but an abrupt
change that happens instantly, and seemingly at random. If seen it happen
before in the middle of an argo capture.

This is a replacement unit as my first one was taken out by lightning this
summer, and the old unit did it also, so this is some sort of design issue
in the hardware or software.
