RKG, I hope you won't take this the wrong way, but your quoted question discloses that your knowledge and understanding of how these forums work, is such that you should not be posting such posts.
Forums are for learning, and swapping ideas right ?
Swapping information here doesnt mean that people are using the forums for illegal purposes. Does this mean, a company trying to buy and program its own radios, shouldnt be able to come to a place like this to get hints and tips.
because programming trunking radios, especially on someone else's network, is not just as simple as asking a few questions on a forum.
Motorola and Kenwood both give week long classes on it. I know, I've been to many. They also cost a ton of money. (at least with Motorola, Kenwood OTOH, didn't charge us).
Improper programming can create problems for the network management, the network itself, and in the case of public safety users, even jeopardize legitimate users on the system safety.
Many of us work in the industry, are power users of said systems, or have other vested interests in keeping the integrity of such networks intact.
As it was said before, too often well meaning hobbyists who lack proper expertise, and proper software and hardware, create headaches they are completely unaware of "just trying to listen".
a scanner never affiliates or attempts to affiliate, with anyone's network.
your question is the automotive equivalent of getting on a racing forum and asking "how do I rebuild my engine of my 1978 Pontiac Firebird" without even the basic knowledge of what kind of motor you have, how to use tools, or general mechanic work.
the links provided above are great info, but it's for people who have a basic knowledge of programming software, Astro 25 radios, differences in flashcode options and firmware- etc.
if all that appears above your head, then you've got lots more reading and studying to do before you get into this.
