Where are you located? - you'll need to be lucky/going some to pick up both the Bridges AND Eldon Square unless you live on high ground near Washington or Springwell Village (my location)

I don't listen to shop security tbh. Never tried. In fact I use my scanners so infrequently it usually means a read of the manual to remember how to work them :o

Hi,

Some frequencies I have are:

456.050 461.55 SHOPWATCH METRO CENTRE GATESHEAD (110.9)
456.8 462.3 HOUSE OF FRASER, GATESHEAD METRO CENTRE
459.125 MARKS & SPENCERS METRO CENTRE GATESHEAD
462.3625 NEXT FASHION STORE METRO CENT GATESHEAD
456.550 462.05 ELDON GARDEN SHOPPING CENTRE NEWCASTLE
456.675 462.175 ELDON GARDEN SHOPPING CENTRE NEWCASTLE
456.75 462.25 SHOPWATCH SECURITY ELDON GDNS NEWCASTLE

However, I have no idea if any of these are valid (i.e. still in use) as more and more people are choosing digital systems.

Obviously the users that have gone digital, bar the emergency services, that dont use tetra but another digital system can be tracked. :?: There must be a scanner out there that can monitor digital signals, not tetra. :?:

There is currently no scanner on the market to decode DMR.

TDMA/FDMA technology is fairly european based and not such a big technology in the USA- yet. If DMR takes off to the extent it has in Europe in the USA then there is a possibility that someone will develop a scanner capable of DMR decoding.

One of the selling points for TRBO and alike is the security the system offers, albeit not anywhere near Airwave (TEA2 etc), but generally speaking it is very hard to decode- unless you know certain information about the system. Unlike a conventional analogue system where you only need the frequencie(s) and CTCSS tone, a digital system would require you to know colour code, group code(s), encryption key (if used). Bearing in mind without the correct group code the radio will not unmute to incoming transmissions and there are millions of group codes to choose from!

I have no doubt there will be a scanner one day to decode DMR, but I think that is still a long way off!

I bought a BCT-15 (Uniden) over in the States a few years ago. The set has all the major frequencies pre-programmed by state , SO I scrolled to Florida, and just let it do its stuff! - ideal for travellers who don't have the facility to find the local important frequencies.

When I mentioned how all our emergency services were scrambled and Tetra etc. the Americans were horrified. A lot of spouses/partners have scanners on at home whilst their loved ones are working for the emergency services - it is their democratic right to have this information! - pity we don't have the same rights.

Reading some of the American forums it seems DMR and NXDN is very popular over there. I think you can listen to the digital systems using a pc and DSD software with a discriminator output socket on your scanner provided they are not using encryption. The problem with digital it is so easy to encrypt, i just cant see a scanner being developed just to listen to a few systems that are not encrypted.

Most of the shopwatch and security systems will now use encryption, thats unless they want to use mixed radios such as Motorola and Hytera because their encryption is not compatable.

Yes, there is some Linux based software out there which allows you to decode DMR.

Many of the original TRBO systems did not have encryption purely for the fact the firmware had not been released which included the encryption function.

Also, it's worth bearing in mind that with TRBO there are 2 types of encryption- Basic and Enhanced. Basic privacy provides 256 pre-programmed keys to choose from. Any radio which has the wrong key will hear garbled transmissions. Whereas, Enhance privacy allows the user to create their own key. Any radio with the wrong key will not even un-mute to allow the garbled transmission!

The whole argument about Tetra/Airwave being so heavily fortified is still up for debate really. I would (personally) rather it be the way it is... I can remember the old analogue days of Police comm's and the sort of information that was passed over the air. Some harmless and some not so harmless. My local force had talk-through enabled 95% of the time, thus allowing both sides of the convo to be heard rather than just the dispatcher.

I's also worth bearing in mind that even back in those days most forces were able to used basic encryption! I'm sure there are a few people on here that the remember the dispatcher asking units to "go key 1/2/3"!

hi woodturningbypaul, i am sure these are the but i think one or two i havent labeled as the galleries, just shopwatch but am sure they are right. 462.25000
453.02500
453.60000
456.02500
I can confirm at least two of these are the galleries. Also theres a strong digital sound, like mototrbo, but you do eventually hear talking after this. :)
