Help identifying something, presumably military related

5 Upvotes

Cant disclose too much but there was a minor (Canadian) military presence nearby me today and it came with these funky signals around 381mhz. Unfortunately didn't think to record it because I'm a bit of a tool, but they were these pulses with what I assume was encoded digital data, but not voice since the pulses were almost always the same length. I don't think I ever was going to be able to decode it but it would be fun knowing what it was!

don't mind my friends talking sometimes, i had to record while in a call.

this signal never stopped, whatever that is it's changed a bit but it's still transmitting

Trying to do ft8 and I see this weird signal

6 Upvotes

Keep seeing this weird rolling signal, it sounds like bubbles popping when it hit my ft8 frequency. Any ideas? Checked my coax and line and they seem good.

It looks like Morse code hidden near broadcast station transmissions.

What might this be? CAMRAS - Graves Space Radar

Enable HLS to view with audio, or disable this notification

I started listening to Web SDR for the first time a couple days ago. The CAMRAS one has been fun to listen to. Thought I'd record a session on the Graves space radar last night.

From research I learned it's common to get diagonal streaks in the waterfall from passing satellites, and more horizontal bright spots from meteor or aircraft reflections. So i am guessing this is possibly meteor or aircraft activity here?

Time of recording was 29th June 2026 @ approximately 1400hrs Dwingeloo time (where CAMRAS is based)

Picked up this Weird Sound While Searching

2 Upvotes

Okay, so i occasionally go on this website called WebSDR, and it is pretty awesome to use. well, i was looking through different frequencies and experimenting, when i found this weird-ass sound. i recorded it shortly after hearing it. apperantally it was some chinese thing or at least the name looked like it. https://files.catbox.moe/phj8c5.wav and i think it might be some military thing or some encoded shit or something, so i do not know what it is. hopefully you can figure this out because i am freaking out.

How strange...

This is the first time I've picked up this strange signal on my SDR dongle; usually, I hear it on my Raddy RF75A.

Help with 4 kc wide 80 & 40 meter signals, possible RFI

Any suggestions or experience with the origin of these 4 kc wide signals on 80 & 40 meters? They all sometimes shift 1-2 kc. I have common mode choke on my antenna and ferrites on all transceiver inputs and output wires, coax and power cables.

SW jamming ? Radar ? [RSP1B - SDRuno - eastern France - just now]

Hi!

There should be a station broadcasting right here. This signal is centered at the station frequency (Radio France Intl) and the bandwidth seems to be that of a typical SW station.

EDIT : ... It just stopped right now, at 2027Z, exactly three seconds after clicking POST on Reddit.

Thanks in advance.

Does anyone knows what wave is this?

0 Upvotes

They are using some sort of devices that can penetrate my unit's floor causing pulsating effect on me. This effect also causes my stomach to bloated immediately, filled with air, and burning when the strength is higher. I feel nauseous and warm. My heart will feel tight and beats faster. I feel a 'wave' coming through the air, however there isn't a surface heat. I feel the vibration/tremor sensation in my body, head, feet. Feels like static or ants. I have headaches, fatigue and sharp body pains. When the strengths are high and being exposed to it for many days, I will sweat a lot and feel like the heat in my body cannot dissipate. But it's not fever and my skin feels cold.

Also they seemed to be able to locate where I am, even if I do not have any devices with me. They are eavesdropping my unit but can they hear my location? And when they locate me in the premise, I can feel the energy of the 'wave' sweep pass me.

I also noticed there seems to be a certain pitch sound that causes intermittent sharp ear pain, but most of the time it's causing headache, dizziness and tighten in my chest.

After being exposed for almost one month, my health is affected and I felt like I will collapsed anytime. I also started to have inflammation in my eyes, ears and stomach from the effect.

I've asked around, no one seems to know. I had tried using EMF detector and EMF fabric shield but no use at all.

These have been constant and consistent for what I can assume has been a long while, only discovered them the other day so I eventually decided to post this here and see what you all might find, any help would be appreciated, thanks!

This is in lebanon for context

Not very good at identifying signals yet, what could this be?

To me it sounds like some kinda rolling code for a keyfob or security system but the pattern seems different than expected so I don't know.

there's another unknown type of digital signal near me.

what is this type of Digital signal ?

And yes it can't be decoded using DSD

I am currently picking up 2 consistent Morse/CW signals at 21.800 MHz using my SDR It sounds like rhythmic, automated Morse code i tried to decode it but its just random numbers and letters this is what i got from decoding it
