Dealers should stop being so lazy and get their act together then.

RAS is there to stop rogue radios tx'ing onto digital systems. Some people are simply too lazy to implement it though.

Basic encryption stops the casual listener, doesn't cost anything, and makes people simply think they cant listen to the transmission.

Combine the both, and you have a fairly robust system.

Every single system we have ever deployed has been both ras enabled, and basic or enhanced privacy. And yes, the client is given these details, so they can, if we ever stop servicing their system, go somewhere else with the knowledge that they aren't locked into us.

The colour code is 1-16. Its not difficult for people to brute force hack it. In fact when we get faced with arsey suppliers, we do exactly that to get into the systems on behalf of the customers.

Which could well happen on a wider basis than it currently is, should the dealers etc want to protect their systems from us because there are some here who want to openly publish access details.

With analogue systems there was little protection from the eavesdroppers. Digital technology has changed that and we can be prevented from indulging in the digital side of our hobby at the flick of a switch if the services wish to do so.

Ok, so other sites may well publish full info, that's down to the site owner, but on here, by gentleman's agreement, we do not. If non-disclosure here helps preserve our forays into the digital world that little bit longer, then I'm all for it.

Meanwhile, in the US, some police departments are keeping a grip on reality:

OFCOM Spectrim Information System
https://www.ofcom.org.uk/spectrum/infor ... ion-portal
shows 456.45 and 456.575
It doesn't give any colour codes nor talk-groups.
