They are using their original analogue frequencies from their existing sites and just changed the radios...

With a digital scanner you only need the frequency. It's only some of these dodgy Chinese radios that folks buy and generaly sell shortly afterwards that you need everything. How to make something essentially very simple into hard work.

I have noticed that on a lot of the old analog frequencies, what was once analog is now digital. There is still some analog stuff to listen too mind.

For anyone using DSD+ FMPx it's very straightforward to follow the voice channels from the nine control channels (numbered 2.1, 2.2etc in the data). I'll post the frequency data below which can just be copied into DSDplus.frequencies. I'll also post the contents of a sample batch file for FMPx.

Set DSD+ to input from Direct FMPx linking and control to combined VC/CC monitor. Run the BAT file for the network you want to follow and you automatically tune back and forth between the control and voice channels as they open.

The return channels from the drivers is around the 148MHz area but tbh you can hear both sides on the TX channel.

Not a good idea to post such detailed information publicly unless you want them to turn on encryption.

There was I thinking the data might be helpful to other SDR users wanting to listen to the London Buses DMR network. Guess not... Perhaps the thread title confused me. Perhaps no-one else uses SDRs.

The channel data is clearly visible to anyone listening to any control channel. It's not some inside ill-gotten info. If I shouldn't post that, is posting shopwatch or airband channels also ill-advised?

Airband is fine because they're not moving off AM anytime soon. Shopwatch it's better not to post anything about if it's not encrypted, especially if the scheme is already on digital because it's so easy for them to turn on encryption. If someone looks up their shopwatch scheme and sees a forum of people listening to it, you can bet they'll be asking their radio dealer to encrypt it pretty quick.

Very much so, it's also worth mentioning that many companies and organisations will trawl the internet including social media for keywords relating to their place of business to gather market data and customer feedback, so it's very much likely that they will find these posts , be alarmed by the fact see it as a security risk and enable encryption..

Yep very sensible advice. It will just result in them going encrypted I expect. There are always the PM where private frequencies can be shared.
