Help Identifying Signal

Hey there, apologies for another video, so much to find out and learn with this hobby. Appreciate all the help from the group and it is always supportive 🙏. Any help with this one please, initially thought MPT-1327 but no luck. Trying SigWiki but nothing similar.

Marine Band Signal

Getting a very strong signal on Marine Band, anyone heard this before 20:00 Avonmouth on 03/12/24. Usually I have just heard VTS and ships, not seen this before.

300 MHz Exploration

Been spending some time exploring the 300 MHz range and found this, I wasn't sure if it was telematics at this frequency, sounds like short DMR bursts. Anyone seen this before who could advise? Thanks as always

Telematics?

Could anyone confirm if this is telematics or something else. Picked up this afternoon in Avonmouth.

OTH Radar? 32.560 MHz

Unid Wideband Signal 32560 KHz at 00:20 UTC 03 DEC 2024 using RSPlay's RSP-1A/SDRuno with a 20 meter length end fed random wire antenna.

I've been receiving this signal at 00:10 - 01:10 daily for the last few days. I originally thought that it might have been originating from the Far East, Russia due to that area usually being open on 10 meters at this time of day/season. But r/FirstToken says he's been observing the signal for weeks, for hours at a time in the Mojave Desert. I left one of my receivers, tuned to the frequency, running all day and I picked it up very sporadically at 10:30, 11:30, and 14:00 PST. Each time for less than 10 seconds - almost like Meteor Scatter.

Today at 00:20 UTC the signal was very strong. I tuned another receiver between 28200 - 28300 KHz looking for any 10 meter CW Beacons that might be open in the same vicinity. I found nothing and switched to USB at 28.300 - 28.500 MHz. Only a couple weak Japanese Hams were audible. Finally I tuned to 10 meter FT8. The strongest station was RW0IM - located in Far East, Russia. BTW, my antenna is directional at this frequency and situated towards the Far East, Russia. Could this signal be propagating from that area?

Identifying new Signal

Hey all, picked up something different that I have not seen before. Still fairly new but getting to grips with identifying more and more (mainly due to support here). I have picked this up from Hampshire (UK) this morning. Anyone know what it is?

I can't find anything on the wiki that looks and sounds like this. There are 2 signals like this when I zoom out, 20khz BW each, around 11mhz-11.1mhz. Heard 1100-1200EST, Michigan.

strange sound at 7270 kHz?

Heard it yesterday. I was quite surprised, because it's nothing like I've ever heard before. I'm sorry for the video, I didn't realise my screen recording went wrong. That's why I don't have a waterfall either. Any idea what might it be?

Weird voice station on 10448 kHz USB received indoors in Northeastern Hungary

Hello everyone! I have found a weird station at around 1405 UTC on 10448 kHz. It was saying something possibly in a Slavic language (“troika”), but that’s just my guess. The signal was really strong, it was possible to receive it loud and clear even indoors in Northeastern Hungary with a normal whip antenna with an XHDATA D-808. The transmission stopped at around 1412 UTC. Can anyone tell me what could this station be, and what does that repeating voice say?

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?

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?

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.

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.
