Interesting Signals

Scanning around on 11 Mhz looking for interesting signals, I came across something I'd never heard (or seen) before.  https://www.youtube.com/watch?v=Gb9RYYOGPg0

Anyone else see this or have any idea what it might be?  I thought it might be OTHR but it doesn't appear to sound like them. 

Thoughts?

    Hello Tom, very interesting subject.. when you have some time checkout KA0KA, Tyler’s YouTube channel. A very definitive explanation on many signals all over the bands. https://youtu.be/_24t1ZZaAhA

    Thanks Art.  Been around the HF spectrum for around 50 years (ham for 41 years and a former CG Radioman) but I've never heard anything like that.  Do you have any idea what that might be?  I don't.  Not the woodpecker of USSR days.  Not the newer OTHR stuff I've heard at other sites.  Not wefax.  Not PSK31.  Not Olivia.  Not ZNI1 or ZNI2 (encrypted analog HF radio teletype).  Not digital voice or encrypted digital voice.  Not DAMA.  Not anything I know of.  Strange sounding operating mode.

    Not really sure Tom, but watching some of Tyler's videos and what he sampled the last 4 months or so is very similar to US Navy AN/TPS-71 Relocatable Over-The-Horizon RADAR...

    Nice.  Yeah, that's what I heard and saw.  That's a rabbit hole that I'm not up to the technical challenge to go down.  LOL!  I also found a great site for different types of transmissions ... https://www.sigidwiki.com/wiki/Signal_Identification_Guide ...

    Thanks Dave ... 73.
