Is this what OTH radar would look like?

But can you tell what a signal is by looking at it, or hearing it? I did run across these.
Quick answer is most of the time you can tell if you have training to interpret the characteristics and prior information about the signal. I'm many decades past what training and information I had in the Navy. Surveillance equipment and over the air signals have changed and are more complex, but the basic foundation of signal identification is the same.

Hal Turner should step away from the SDR monitor and read about the Cuban Missile crisis or the Able Archer 83 exercise.

Two E-6B TACAMO aircraft were up Saturday - one up the West Coast and the other was out of Kirtland AFB flying elongated ovals at angels 25 over NW NM.

Slides on the AN/TPS-71 from a talk I gave on various sorts of HF radar.

Not unusual TACAMO activity. I have seen similar activity by TACAMO a couple of times a week for years.

I do not think my slides on AN/TPS-71 attached. So here they are in a different format. by the

Here is an article I wrote on the Russian"Woodpecker" radar 37 years ago. It is amazing how much conspiracy nonsense has centered around a simple HF radar.

Is this an accurate visualization of that Over The Horizon radar would look like?


I don't know, should I be taking that linked article as parody? Humor? Intentional hyperbole? I have never listened to or read anything by Hal Turner before, so I don't quite know what to take away form the piece.

What is being called a "jamming" signal in that article, is not. It is the radars he says are being jammed.

Image number one in the article, he says "Massive jamming of radar is taking place continent-wide in Europe, including over-the-horizon radar needed to detect incoming missiles. As shown above, massive jamming signals are being emitted."

But the picture shown is the spectrum of the Russian 29B6 Kontaynar radar, not a jammer. What he is claiming is a jammer is the radar he says is being jammed.

All four images in that piece are waterfalls showing radar. Image one is the Russian 29B6, image 2 is also the 29B6, image 3 is probably the British PLUTO radar (but would need to hear audio to confirm), and image 4 is two 29B6 radar beams.

The Russian 29B6 can emit up to 8 simultaneous radar transmissions, while the British PLUTO can do up to 4 simultaneous transmissions. They all move around in frequency, leveraging current propagation conditions to achieve coverage in the regions they want to paint. These signals are on the air, to some extent, every day, for the most part all day. It is not uncommon to see all eight 29B6 beams, but it is more typical to see only 1 or 2 of the PLUTO beams.

Both 29B6 and PLUTO tend to move down (in frequency) during the afternoon / evening (local time for them), and shift up during morning / early noon. 29B6 bottoms out at about 6 MHz, and PLUTO bottoms out at about 8 MHz.
