Also looking at Paddington station DMR freq. Anyone with info to share please do pm me.

Thanks

453.550 DMR . its a CAP+ system though so multiple other channels

Is it encrypted and do you know the tallkgroups and colour codes?

Cheers

Paddington not encrypted. Don't know about the talk groups but it's colour code 8. There is another DMR channel at Paddington on 453.9 MHz also colour code 8.

Reading station on 453.275 MHz colour code 5. Reading traincare Depot on 435.55 MHz also on colour code 5.

Thanks Chris for the helpful info. When I go up in 2020 I will see if I can do more decode. Merry Christmas and a new year to you bud.

No problem and happy new year to you. Ive got a couple of Baofeng 1801 on order which should help me with Talkgroups etc.

It looks as if Paddington alternates between 453.550 and 453.900 MHz every so often. There appears to be alternative frequency for Reading station but I know not what it is....

No luck with talkgroups as yet, there must be something I’m not doing right with the Baofeng 1801’s....

You dont need the talk groups. Just put the frequencies in your scanner at it will do the rest.

I realise that (I took the AR-DV10 to work with me which is how I got the frequency / colour codes) but the question was asked about talk groups etc. Hence my leaving the DV10 behind and taking the Baofeng 1801 instead. In theory at least if you bang in the frequency and colour code the Baofeng should display the talk groups when the channel is in use. Possibly need to take the DV10 up again, not going to Paddington all that often at the moment to be honest.

Hi.
I realise this is an old thread, but I was in London last weekend (21st January 2023) and got hits on :
Paddington
453.5500 - Colour code 8
453.9000 - Colour Code 9
456.4000 - Colour Code 9
460.0500 - Colour Code 8

Reading
453.1750 - Colour Codes 4 and 12
453.2750 - Colour Code 5
459.7750 - Colour Code 5
459.6750 - Colour Code 4

Hope that is of use or interest to someone!!

That's both the inputs and outputs

Paddington
453.550 -460.050
453.900 shouldn't that be 460.400 or is that a simplex

Reading
453.175 - 459.675
453.275 - 459.275


453 frequencies unless they are simplex have a 6.5 MHZ split. Stations can be either simplex or duplex

Its not impossible to have more than one frequency at a station. Liverpool Lime Street has Network Rail who manage it on one frequency and Avanti on another, the MerseyRail on the low level trains a different one again

Radio Reference showed me 4 frequencies for Network Rail:
453.550 & 460.050 - user name "Network Rail Infrastructure Limited Paddington"
453.900 & 460.400 - user name "Network Rail Infrastructure Limited"
(Search Network Rail at postcode W2 1HQ +1mile)
which I saved into the scanner and got hits as reported!

I need to have a day at the various Central London stations to get more info (I have frequencies shared between Paddington, Euston and Kings Cross from RRUK!)

If you are close enough you will hear both input and output, if you look at the RRUK frequencies they have an R or a T beside them, R for Receive (output) and T for Transmit (input). what you put has 2 R's and 2 T's
