It's been going for two days straight right on the international call frequency. Sounds much like an old school over the horizon radar........almost but not quite like the old Russian "woodpecker" that was on shortwave forever.
There are several clues that it is a jammer and not a real radar. It lacks the preceding two or three beeps that the real ones have, and more tellingly, it is operating at a single frequency and on a regular pattern.........real OTH radars operate at random frequencies and the agencies operating them go to great pains to make sure there is no discernable pattern of transmissions.
This jammer on the other hand seems to operate on a more-or-less 15 seconds on, then 45 seconds off basis. Roughly 5 pulses per second.
Sometimes the silent pauses are longer but then it goes back to the regular pattern. It is centered on about 27.553 MHz...making 550 and 555 pretty much unusable here. And it is very LOUD! S9+20 at least.
I long for the old days when people respected 555 as the international call channel and it was rare to hear monkey business and jamming on there.
