This is a great point. There is also a ham vhf site (I'll look for the URL)
posting his FM (88-108 MHz) DX reception reports over the past two decades.
The top end of the U.S. FM band is a good indicator of sporadic E as well as
tropo propagation. It's amazing however how frequency sensitive the MUF (or
in this case MUEs) frequency can be; oftentimes the top end of six meters
will not support Es while the low end will. It would be great if we could
get more 144 MHz and 222 MHz beacons. On of the Great Britain ham web sites
contends that the U.S. beacons are not very useful because we run so little
power compared to the beacons overseas and in Australia. Hmmm???

Subject: [VHFcontesting] Eskip detection
Reading W3ZZ's article on Eskip the most recent QST got me thinking about
Eskip detection again.
Last summer I got in on a few 2m Eskip openings and this got me to thinking
about more automated widespread ways to detect signals.
What you really need is some automatic way to ID the transmission source.
You also need as many transmitters as you can get. One thought was to use
the NOAA weather transmissions at 164 Mhz. They are on 24 hours a day and
only on 7 frequencies. This would be very good to use as an indication of
222 mhz Eskip.

Now if they just had some sort of data stream that would ID them 24 hours a
day. Last time I checked they did not have anything like that running on
their signals that was on the signal all the time.
They do have it for special weather alerts.
