IIRC there is a frontscatter site in Norway that would serve any
Alaskan long range detection.

There's been a lot of noise heard in South Africa on the 160m band in the
last few weeks. It got so bad that it just about ruined a recent "Top Band"
contest. The source has tentatively been identified as a Loran transmitter
somewhere in the Far East. I've heard stories from some older hams about
"the woodpeckers" and the trouble they caused.

One of the great ironies of radio is that most of the early research
was done by amateurs. In 1920 there was a conference in Washington
among the Western powers. They came up with the first radio frequency
allocation chart (as opposed to a list of frequencies). The chart
clearly states that anything above 1500 kHz is unusable and is
reserved for amateur and experimental. Wonder what property rights
like that would bring today?
