Mobile Network??
Hi there, receiving this very strong signal this evening in Gravesend UK at 18:45. Is this a mobile network at this frequency or something else. Is there anything that can be done with this (not decoding calls texts ) but identifying the network or something?

Found another signal I haven't seen before usually don't find much between 250 and 350 MHz except a load of TETRA but found this tonight in Gravesend UK. Anyone know what this might be?

Interference?
Picked this up tonight in the UK at 20:04. Having a few hours to see what's out there. Have tried a few different modes but not getting anything recognisable. Is this just interference?

Hey there, picked this up in Gravesend UK tonight 05/11/24. Not heard anything like this before, could anyone assist with identifying this? Thanks

Any idea what this could be?
That little chirp between 445.28-445.32MHz.
I would be also interested in those lines little higher. There are .001MHz bands, 8 of them they are what seems to be empty carriers, and together they change slowly like a binary counter.

Curious what this is. Started within the last 24h or so. 466M. South Hampshire, UK

Tetrapol?
A few weeks ago several carriers appeared that seem to be tetrapol, but I'm not sure since I can't find any information about tetrapol on 800mhz.
There are other Tetrapol carriers on 390 Mhz but I don't think they are harmonics of these. I'm in Mexico City.

CW at 174.2 kHz
There is a stream of morse code on this frequency. Approximately one letter every 7 second. And the morse code is long way from perfect even though it is easily read.
Anyone know what this signal is, who sends it and the purpose of it? Is it some sort of number station?

What is this frequency from?
18:27 UTC
I was playing around trying to see what all I could pick up and I came across this.
For reference I'm in southern Arizona in the middle of nowhere. It almost sounds like it's the audio to a TV channel because there's ads mixed in, is that possible? If nothing else, could someone tell me what that frequency is supposed to be used for?

I see this during the day, it is not constant, some kind of pager?

Hey all, scanning through some frequencies tonight and in the 500 MHz region, small movements in the frequency display variations in noise floor and look like some kind of signal. The signal is fairly wide but not there until the frequency selection is in a specific spot. Is this just the noise floor moving up or down?

Why is it like this?
Ive got an SDRV4, and an antenna connected (terminated with PL connection). whenever I tighten the connection between the Antenna and the SDR, theres noticable signal loss, and when I loosen it all the signals and some interference came back.
any Idea why its like this? and how to prevent it? Thanks

Strong frequency in my rental home. Actually painful and tormenting to the ears and causes headache.
Could there be hidden devices causing this? What could be causing this?

I have found a very strange radio frequency(shortwave ~7 mhz) where there are almost alien like sounds
Does anyone here have an explanation of why how and what this is??
