Listen very carefully. Theres a voice in the noise too.

Props to u/Firedogman22 for best possible response. There's nothing "numbers station" about this signal but it's also not exactly obvious what it is. (It looks a bit like a time signal, to me.)

Personally im doubting time signal, the beeps are too irregular, and theres no active time stations in that frequency range. If its a frequency marker than its honestly a kinda shitty one, maybe if the frequency is ment for more covert russian comms it could be possible but still. Personally listening to it more im thinking it could be some kind of propagation beacon or signal

I'm not following you on the irregularity of the beeps. Are you familiar with the long-standing Russian use of single-letter Morse beacons? I don't think anyone in the English-speaking hobby is sure what they're for, possibly channel markers, possibly propagation tools, but they're as simple as that- the broadcast a single letter continuously. Except this seems to be in double sideband, and the SLHFBs aren't known for that AFAIK.

What I mean is for the time station theory, the beeps are too irregular and quick for that, usually time stations beep at second intervals, changing tone when they hit a minute. This station itself has its beeps seperated by 1-4 second intervals. I am also familiar with Russian morse beacons, I dont think this is CW or that there is CW in it, but I also havent had the chance to analyze the audio.

Apologies if you've already answered this, but have you looked at the live signal? I ask because OP's recording isn't a great representation but web SDRs in Europe pick it up very consistently. And the signal is very consistent, itself- check it out if you haven't already.

I havent had a chance too, my internet has been super spotty recently, I’ll pop open a SDR and see what I can find

After looming at the area with russian websdr, there absolutely is something there thats odd, the waterfalls seem especially weird, i cant hear any audio as websdr audio wont work on my phone

[–]Firedogman22 0 points1 point  (0 children)

Theres also periodic beeps on the sidebands that you can see on the waterfall.

Ignore my previous message, ive gotten it to work better and its pretty damn uniform now, could be a time signal but I don't believe time stations is operating there. More than likely a new channel marker

[–]GarlicAftershave 0 points1 point  (2 children)

I agree it's on odd range for a time signal. It's such a close match for the "T Marker" Monolith-type station that I'm inclined to assume that's what it is. If it starts sending Monolith voice traffic at some point, that would be conclusive.

[–]Firedogman22 0 points1 point  (1 child)

Personally I havent heard a monolith station, is it usual for the channel marker to be a beep like that?

[–]GarlicAftershave 1 point2 points  (0 children)

Different command posts use different marker signals. The Buzzer (aka UVB76), the Pip, the Squeaky Wheel, etc.

[–]Firedogman22 3 points4 points  (3 children)

Its odd, so to me it sounds like a high pitched electric turbine, usually thats caused by the sun getting fucky. However those beeps SHOULD NOT be there, do you know how much power the signal could have been radiating and from which direction, I can try locating it later tonight

[–]GarlicAftershave 1 point2 points  (1 child)

Have you tried the TDOA feature on the KiwiSDR network? I may give it a go in a few minutes. ETA: Tried TDOA, never got consistent results.

[–]Firedogman22 1 point2 points  (0 children)

Havent tried that, I usually use a shortwave handheld

[–]HabanaDhalia200 1 point2 points  (0 children)

I’ve also been receiving those odd periodic beeps too, considering this is shortwave it would more or less be anything.

[–]12kdaysinthefire 0 points1 point  (0 children)

That’s crazy, all the way back in ‘85 too

[–]Awexes25 0 points1 point  (1 child)

yoo i found same thing on FM radio

[–]Awexes25 0 points1 point  (0 children)

idk whats the frequency because its an old analog radio, but its something like 77 MHz
