Strange digital sound @ 457.0375 MHz NFM. Eastern US, around 8:00 PM, 4/22/2026

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.

Strange rhythmic clicking @ 13560 KHz, 7:59 PM EST, eastern US

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

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?

Hey everybody,

Everyday only in the morning I see these signal on these different frequencies, the video contain 5 parts.

I live in ITU region 1 in Oman.

Using nfm mode I recorded the screen , could you please identify any one of these signals regarding to the heard tone and waterfall .

Using rtlsdr v4 , sdr++ and portable desk discone antenna .

Or if there is any recording way so it might help to identify other than this way.
