    Not really- as I understand it, the sounder is only on briefly while the actual radar runs for much longer at much higher power.

    Its obvious you ain't heard it yet , try to listen watching the clock instead of reading about it intellectually , 1 to 2 hour transmissions is not what i call brief , maybe on another planet it might be brief? , even the old woodpecker used to go for hours and then days , that one also on 80M for several hours at a time .

    You are quite wrong and do not have a good understanding of radar, satellites and surveillance systems.

    The reason these HF OTH radars often overlap into other service bands is due to varying propagation. The same reason we hams use different bands at different times of day, week, year.

    This is no proof of intention to interfere. And even casual listen reveals they are poor jammers. Anyone old enough to remember the Cold War as an SWL'er knows what 'real jamming" is like. Further, none of these radars use modulation methods well known to be effective for jamming.

    Satellites are not typically used for providing surveillance/tracking of ships and aircraft by radar. The last time the Russians/Soviets had a RORSAT, Radar Ocean Reconnaissance Satellite was around 1993. I've never heard of a radar satellite for aircraft detection. RORSATs are not good choices for tracking ships since they generally have only a few minutes of overhead time. However they can provide 'snapshots" of ship dispositions in ocean areas. Correlation and identification of target ships is problematical.

    HF OTH Radars while not having high location precision, are capable of detection and tracking ships and aircraft. The fact they are now fielded by many nations since their introduction four decades ago proves their usefulness.

    Back in the day we used to try to jam the wood pecker... Turn the beam in their direction, crank on the amp, and start calling CQ...

    Actually, it's purpose is MIND CONTROL! They are trying to gain control over your mind in preparation for the next U.S. election cycle.

    That's why the 1st audio i posted had a crossover/mixed at the start for a few seconds and then reverted to a clean Helicopter , i tried replaying it on AM tx but then realized those signals are so wide i deemed it a waste of time .

    Hi all,
    In the early 70's I worked on the AN/FPS-95 system. This was an American OTH radar called Cobra Mist at RAF Orfordness in Suffolk Britain. We pointed the other way, we ran MW's, I often wondered what problems we caused. When I was home on leave and listened you could tell the range it was working by the PRF. Brings back the past

    I enjoyed going TDY to the UK while I was on active duty! Nothing like a good pint of beer to start the evening off on the town.

    Wait til the HOA gets a look at this antenna submission!
