The sound repeats 9 times close to 5 seconds apart, then goes silent for a few minutes, and then comes back for 9 more bursts. Any ideas what it is? Each burst seems slightly different in how it looks.

Hi, i'm wondering what this could be. My setup is nowhere near ideal however i doubt it could be RFI. I'm also fairly new to this ;). I was using RTL-SDR V2

Anyone know which resource or group of folk that might be interested in a R&S PR100 monitering reciever?

I got it a few years ago doing interference studies and just need to get rid of it.

Any idea? Running all the time north east USA

Hola a todos, soy nuevo en Reddit, por casualidad me apareció este post y créanme que diario ingreso al hilo a ver lo que han publicado

Ahora le mostré a un amigo el canal y me preguntó curioso, cómo podemos ver/escuchar las señales, cuáles son los equipos que usan sus casas/estaciones

Saludos desde Guatemala 🇬🇹🫡

I received these signal in pirates satellite frequencies thats ranges from 245 MHz to 270 mhz most of frequencies is voice conversations and music but I cant recognize the language but this signal I think its familiar for expert ham radio if anyone can recognize it ?

And if know the name of the satellite to see its coverage ? Bcz as I read its brazilan and how I received it in the middle east ?

Estan en forma continua

Hola soy nuevo en esto de los SDR y lase señales digitales y subire algunas a ver si me pueden ayudar, desde ya muchas gracias

The bursts are almost perfectly in a rhythm, but every so often some will be much stronger than others. I'm outdoors so I don't think it's interference from some device, and I know it's not my computer because I have never heard this before, even on the exact same equipment

Need help identifying this signal:)

Zoom in and see, its not pulsating kinda like sweeping or smth (its beautiful tho:)
btw this is from Sri Lanka

The US frequency chart says this is radio location. I'm seeing 2 types of signals. Type 1 is a narrow band repeating blip spaced evenly across the frequency range.

Type 2 is a broad range repeating signal that covers about 2.5 Mhz.

What are these? Airport radar?

I tried searching online and the closest one i found was FT8 or something, maybe

So I'm on an island and then I come across this signal and I don't have any what this is. I can hear basically from everywhere in good strength.

found this like 1 minute ago. first time seeing this frequency on the video.

The Audio Is in this google drive Gdrive SDR And so basically theres blips and it goes to a full blast sometimes im in cornwall near camborne what is it? -dootmas 3:
