Thank you for including more modern ones.  They could still be out there or return.  Most videos show only the ones that we've all already seen a hundred times and that quit back in the 1990s.

Some of these are genuinely spooky. I love the presentation style you have going here. Hopefully your channel gets more recognition. You deserve it.

4:12 it can be rwm

8795 goes hard

SYRINX? That's some RUSH 2112 stuff! Showing my age.

Judt discovered your channel. I always enjoyed strange, odd, bizarre, and unknown radio, be it terrestrial, CB, or SW radio sounds. I enjoy the modern ones you've included, as well as the older ones. Great job on these!!

The "56k" noises are actually a fax preamble. It's possible to decode it, maybe it contains something important.

The trumpets one is us military reverie

08:32 sounds alot like those "zombie satellites"  whose batteries have become conductive, thus the panels directly power the circuit erratically.

Hey, I'm Greek and I heard on The Spanish Man counting numbers in Greek "Ένα, Δύο..." Even he's Spanish!

the xpa family mode is probably XPB or unless it isn't it sounds much like it

I'm really liking these vids man. Radio anomalys have always interested me. They arent inherently scary but I could imagine if you're just chilling in your house monitoring the waves and find a numbers station how spooky that might feel.

THE INTRO WAS SOOO GOOD!... Anyways back to my annoying notes for every oddity.

UVB-76 DIAL UP ODDITY - Voices seem to be in Russian and not French, I can't figure out what are they saying but I can definitely hear спасибо (spasibo) "thanks" at the end of the message at 1:09
THE SPANISH MAN ODDITY - This is actually extremely interesting because there's an entire language that is whistled rather than spoken used in Spain. Its name is Silbo Gomero and it's basically the Spanish language interpreted as whistles with different pitches. The voice is definitely a bit eerie.
TRUMPETS ODDITY - Could be a channel marker... I think.

Great video, also I like that editing style :>

Mostly if you look 19 khz up or down. You will find activity. Most have mixed signals "side bands." The same is true with WW2 wsm(r) as the broadcast music covered the teletype."riding on the 650 signal down or up". Big secret back then. Oss business. So if you hear the watch the "Birdy signal" look down or up for  traffic.

If you really read your comments, those aren’t “trumpets” but standard US Army bugle calls.  Prior to the 20th century commands were communicated to troops in the noise of battle or parade thru bugle calls.  A small number were retained for basic ceremonial use by all US service branches.
The one in 13150 is ‘Retreat’ and is played on US military installations at the end of the duty day, immediately preceding ‘To the Colors’ or the Nat’l Anthem.  The one in 14028 is ‘Revellie’ which is played at the beginning of the duty day.  I couldn’t make out the one on 13438 bcz it’s such a poor recording, and only the last notes are audible in the 3 times it repeats in the video, but it’s also a bugle call, though not one frequently used.  It’s possibly ‘Recall’ but w/o hearing it more clearly & with more than the last half dozen notes it’s hard to be sure.

Cool video, and audio of course.
Most sounded like terrestrial satellite up links.
I'm open to corrections.

@8:58 Fishing Buoy?

10:43 probably a kid messing around with his papa’s amateur radio equipment, using a morse haha! Great video man, keep up the good work! 😊

19047 kHz is XPB, it goes too fast to be de-coded
