[Lowfer] WEOH signal plots

Cool Lyle.

Should I change something drastically here now? LOL!!! How about if I take a
rope and hang it off the lower run for the cat to play with? He should be
able to get the wire swinging pretty well which should make the single go up
and down. Hi hi hi...

I'll leave it alone for a few days.

Semi-live plots of WEOH are now available at
http://www.cpinternet.com/~lyle/weoh-plot.jpg

The plot is updated about 2 minutes after the hour and half-hour, and shows
what the signal was doing during the previous 40-minute period.

WEOH is about 70 miles south of me and is transmitting on an east-west loop.
My plots are generated by DL4YHF's Spectrum Lab software, with inputs from
three different receivers, each connected to a different antenna. The
north-south receiving loop is my multiturn, tuned 8-foot loop with an
IC-756PRO receiver; the east-west loop is a single turn 10-foot loop going
through a simple downconverter ("software IF" receiver), and the LEK LowFER
vertical is connected to an HP3586B selective level meter. If there were no
skywave propagation, I would expect the N-S loop and vertical to have good,
constant signal levels, and the E-W loop signals to stay fairly close to the
night-time noise level.

The plot colors look great in SpecLab but obviously lose something in the
capture process. I can understand the fuzziness but don't know why the black
background turns to purple...
