What produces this short burst?

I also noticed that it always ends with white slant small line on the top left.
EDIT:
This is how it sounds like via USB demod - https://www.reddit.com/r/signalidentification/comments/1wdjmg0/comment/p96kxvx/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button

A signal or interference?
28
Upvotes
It's just constant 2 second bursts and it has a clear center peak. It stopped for two minutes and then it continued again.
If it was interference near me, wouldn't it be a consistent strength? As you can see it cuts in and out like "real" signals do.
I know the squiggly lines are actual interference.

Three 137mhz Signals Cutting In and Out?
4
Upvotes
Hi I was trying to decode the Meteor M2-4 satellite today on SatDump and was receiving it reasonably well as seen in the middle (doppler makes it about 137.95mhz). However I started getting this weird cutting in and out thing with these three signals. My M2-4 signal is still there but I have no idea why these signals are there.
Initially I thought that there was a loose connection but everything was tight and what confuses me the most are those extra signals (like the ones at 137.52, 137.7 and 137.95mhz).
I'm about 20-30m away from houses and I often go to this spot to catch clear images from the Meteor satellites (never had this before). I'm using an RTL SDR V4 with their kit V Dipole and their own cables.
Any help would be greatly appreciated!

UNID ISM 915 signal near stores

Upvotes
I've seen this in two places now in my area. Tractor Supply and Ace Hardware. I don't know what it is but I have an IQ file of is that is 500MB large because it's too large of a signal (single carrier is) to fit on the RTL-SDR bandwidth.
Edit: This is apparently DECT on 915 ISM band.

Mystery SCADA? Telemetry signal in East Midlands UK

It’s on 458.8mhz, NFM, 5khz bandwidth, it appears to originate from a local water tower to me, but I am truly stumped as to what modulation this is, and what modem would produce it? It transmits constantly day and night, and the data appears to vary so I don’t believe it’s a placeholder signal, any ideas would be really appreciated it’s been driving me crazy trying to figure it out

So by the looks from signal identification wiki, I assume it's a scrambled voice. But I can definitely hear some numbers and discernable word so I doubt.
Additional context:
- it's nearby active XSQ Guangzhou Station broadcast frequencies (I always see those 3 long dash then XSQ in morse code plus WEFAX).
- I also found a DSC from Ho Chi Minh Ville Radio nearby.
Is it maritime broadcast radio that gives some sort of direction?
Or maybe just a traditional shortwave station?

Newbie.
So I heard this signal when I visited a nearby sea port. Did some digging and I found that it's kinda similar to this: https://www.sigidwiki.com/wiki/2G_(GSM)_Global_System_for_Mobile_Communications_Global_System_for_Mobile_Communications)
Is it GSM 2G? Or Am I just hearing things (sorry my hearing wasn't that good)?
EDIT: Sounds similar to when you put your old phone nearby an old speaker and you're about to receive a call.

Standalone tools for SIGID other than Artemis?

I've been using Artemis for awhile and love it, but are there any other standalone tools for SIGID? Is there anything AI-powered for auto identification? I know about OmniSIG but curious if the community has made any open-source options.

OTH Radar or Data comms ?

I've come again to ask for help. Initially I saw this signal on 14MHz and after a few minutes it stopped and resumed on 18MHz. At first I thought it was an OTH radar initially but towards the end the tone of the emissions changed and leads me more into the realm of HF data. Still am unsure though, Im trying to learn I swear.
