I guess we have an urban myth on our hands. (Better
for April 1!)
I've verified to my satisfaction that this signal is
coming from local TV sets. Turning one set off cuts
the signal by a large factor. Tuning my 2 sets to the
same channel eliminates the beating tones that I get
when they are set to separate channels (with slightly
offset frequency standards). Etc Etc.
So this is generated in all our TV sets. The 8th
harmonic of the 3.579545 MHz color reference. Pretty
much everywhere in North America! Can we all go home
now? [Why the 8th harmonic? Beats me.]
This signal is a good frequency standard as an
alternative to WWV. The carrier is at 28.636360 MHz
+/- a few Hz between the various TV networks - maybe
with some 60 Hz hash. With the Orion, I compared this
against WWV and it agreed to better than 0.3 ppm.
