Strange Signals & Weird Noises On Your Radio Scanner Explained

[bentleybloke]

Only just found this video and it was a Eureka moment as I have heard these tones and transmissions for years. Thank you for explaining this to us.

This is a video I've wanted for so long but never thought I'd get! I have wondered about the sound at 2:51 for years! I never knew the purpose and could never explain it to people when I asked for answers. Great video and very insightful!

This is probably one of the best video's you've done so far. There were a few weird bleeps I've heard in this clip that were a mystery before watching this video, and I've played around with radio kit of some form for most of my life as a kid and an adult. I believe this could be a continuing series of videos with more weird and unknown bleeps heard through the radio spectrum. Brilliantly researched and presented.

As Mike ( comments ) said you must have put a fair bit of effort into that video, research, finding photos, etc. Then making the video itself, you deserve more views ! Well done

You've done it again. Fasinsting and clearly explained as always

3:55 It’s worth remembering that your car can be stolen this way. For example, a car thief standing outside your home and cloning your keyless entry keyfob through the walls, then repeating the signal to open your car door and even getting the start/stop button to work. When inside your home, keeping your keyfob inside a faraday cage or faraday bag will stop a thief.

These sounds are always so haunting to me, im not a radio listener or hobbyist but i enjoy your channel! I remember back when my brother and I would use the radio many years ago, i had a phobia of radio static and these noises still creep me out for some reason. I know its all innocuous and normal things now, its just strange to hear all these sounds. Its like an invisible (inaudible) world of machines all shouting at each other and listening to them through a radio receiver is like hearing the sound of a thousand voices screaming all at once....

Still playing catch up but loving all of it, thanks again 48-70🇬🇧👍

Really good Lewis!
Not many videos have gone into this sort of detail.
A part 2 is definitely needed!

That Pro32A was my first ever scanner from the days of Tandy

[OutlawTwo]

2 years later and this video is still helpful with understanding the meaning of different sounds when scanning. Thanks!

I remember those Bleep, Bleep bleep Bleep tones followed with a voice sayIng the recipients name saying please call (this # phone number). These tones dominated the 1970’s to 80’s VHF band but disappeared in the 90’s.

Heard many of these sounds over the years. Brilliant and informative video. I used to decode pocsag a lot.

The excitement of radio scanning dwindled once mobile phones and emergency services went digital. I still have my old PRO-2004 scanner which used to burst into life around 4pm each weekday with mobile phones.

Great stuff. I love the look of that Realistic Pro-32.

Be aware, there is a rental company out of California that has gotten a massive number of FCC licenses to use with burst transmitters on telephone poles. They have been given licenses in virtually all bands, and many of the frequencies are already licensed to commercial radio companies. They tend to use them in areas of lower population to transmit any information about electrical use to the various electric providers. Despite them being licensed for lower power, they are interfering with various radio communications providers. This is from personal experience.

Lewis it’s not just the police that use Airwave. It is also used by ambulance, fire and lowland search and rescue. It is also extensively used by HM Coastguard, the real 4th emergency service to communicate with the other emergency services as well as with the coastguard search and rescue helicopters. The coastguard also use MF, HF and VHF radios with HF being used as the secondary comms for the helicopters.

Also the pagers have all gone from the coastguard with the exception of their VHF channel 0 pagers used in area of poor mobile coverage.

Lewis one of of the best informative videos you have done thank you and keep them coming

Excellent video Lewis. My first scanner was the Realistic Pro 32, and most of those signals I come across - thank for for letting us know what they all are.

[waggonfm]

Brilliant video, have been mucking about with scanners since I was a kid and always wondered what the digital noises were.
