Topband: Unknown Pulse Signal Wiping out 1900-1925 kHz

[Mike Waters]

I found something interesting on http://www.codar.com . Take a look at the
changing graphic on the main page, which shows different places in the
world where these are installed.

You need to watch it awhile, because every so often a new location appears
in the sequence. Among other locations, I saw Alaska, California, and New
Jersey.

That's all I had time to look at on that site. There may be other useful
info there.
