Quote from Internet:
OTH Systems: CCCP USSR/Russia
The Soviets had also studied OTH systems starting as early as the 1950s.
Their first experimental model appears to be the Veyer (Hand Fan) that was
built in 1949. The next Soviet serious project was Duga-2, built outside
Nikolayev (on the Black Sea coast near Odessa). Aimed eastward, Duga-2 was
first started on 7 November 1971, and was successfully used to track missile
launches from the far east and Pacific Ocean to the testing ground on Novaya
Zemlya.
This was followed by their first operational system, known in the west as
Steel Yard, which first broadcast in 1976. Built outside Gomel, near
Chernobyl, it was aimed northward and covered the continental USA. Its loud
and repetitive pulses in the middle of the shortwave radio bands led to it
being known as the Russian Woodpecker by amateur radio (ham) operators. The
Soviets eventually shifted the frequencies they used, without admitting they
were even the source, largely due to its interference with certain
long-range air-to-ground communications used by commercial airliners. A
second system was set up in Siberia, also covering the Lower 48 as well as
Alaska.
End of quote.
From middle of 1980's woodpeckers is QRT. There was 3 main TX sites, two in
Ukraine,
other on far-east of Russia.
Now about one year there is big radar QRM on 10 Meter band, but its not
sounds like woodpecker...
Its like a wideband grid of carriers that TX for some seconds, then pause
and again TX but with some shift of frequency.
Many hams here find direction by antenna to Middle East, so may be Iran or
Israel setup some new HF radar systems...
