Thoughts:

1. Lots of devices use colorburst crystals. Every home likely has at
least one or two.

2. GPS satellites aren't in geosync orbits.

3. I've been listening around the freq in question since this started,
and all I hear is the same ole colorburst harmonics I've heard for 25+
years.

4. Unless it's coming from a TV device that's locked to a broadcast
signal, it will be all over the place and somewhat drifty.

5. I've heard colorburst harmonics that are relatively clean and
stable, and harmonics that have all sorts of interesting "modulation".
And everything in between.

6. I bet some of you are hearing a signal on 146.76 MHz too...
(Especially on an RS HTX-202, which uses a colorburst crystal for the
CPU clock).



I stick with my original opinion. It's a colorburst harmonic right in
your own backyard that everyone is hearing.
