DMR Scanning London & the South East

Post by Werthers »

Why not post a comprehensive list of your own finds and invite others to add to it? You are more likely to get responses by doing that.

That's a very out of date list from Radio Reference database. https://www.radioreference.com/apps/db/?ctid=4452

Good luck with those, especially ones like " Chelsea and Westminster Hospital" in the middle of the Airwave Tetra band.

Until tomorrow night you'll find a lot of analogue Wimbledon TV talkback freqs around 447, 450, 452, 455 and 457MHz

Since I''m nice here's my DSD+ frequency data for London Buses DMR network.

Re: DMR Scanning London & the South East

Post by Werthers »

I gathered that after trying those. Some of the frequencies are still active but the DMR info is out of date.

I think the best route to go would be getting one of those SDR receivers and software to decode DMR signals that will provide Color codes, time slots and talk groups.

I'm newish to DMR so I'm not fully clued up on everything just yet in the world of digital. I can write DMR codeplugs but thats about it.

As for scanning what bits would I need and software?

Can I use an analog scanner with the audio feed plugged into a computer using some kind of software to decode the digital noise from the scanner and if so what software do I need?

If I can find some way of scanning DMR signals and obtaining the info I need I'd be more than happy to post my findings on here and as well as making up some scanning codeplugs to share with others.

Sell some of your old crap and get a digital scanner, makes DMR reception a doddle, does it all for you.

What DMR scanner would you recommend?

The Whistler TRX1 or the Uniden 3600.

Thanks Mike I will have a look at them I'll probably go with a base version rather than a hand portable one. :thumbup:

In that case a Whistler TRX2, the base version of the TRX1.

Plugging a lead into the headphone output on an analogue scanner won't work for DMR decoding. You need what it known as a 'discriminator tap' output - basically unfiltered audio. This maybe possible as a hardware modification. The only software to use is DSD+ which is USD25 for lifetime support and updates. Well worth it for DMR decoding including text and location data. It'll also decode D-Star and Fusion the hams use as well as P25 which doesn't seem to be used in the UK but is useful for online SDRs.

I use an SDR which is cheaper and possibly more versatile than a stand alone digital scanner. My Airspy R2 is excellent on VHF/UHF with a Diamond discone - £200 versus £380ish for a second hand Whistler base scanner. it might be worth downloading the SDR# software and trying out the online SDRs to see if it's for you.

It reminds me of when I bought a BBC Micro computer back in the 90s when I was a kid and it ran a programming language called BBC Basic and I was always plugging things into the tape audio input of the BBC Micro to see what text I'd get on the screen I could even get data text off PC CD ROMS but its a shame the same wouldn't work for a analog scanner to PC via audio feed. Wishful thinking I guess.

Thanks I will look into that. I've never owned any Uniden radio stuff but have heard from other radio users that Uniden radios have good ears.
