• Effective immediately we will be deleting, without notice, any negative threads or posts that deal with the use of encryption and streaming of scanner audio.

    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

Please help me understand

I just bought a new BCD396T. When I tried to program a digital system I chose P25 but couldn't recieve anything. I tried programing it as a standard Mot. 800 and it worked. Why is this? Thanks for all help.

If it's a 3600 baud system, then it can use both analog and P25, so you need to use Mot 800.

If it is a 9600 baud P25 digital only system, then you use P25.

If it's a P25 system the database her will show it as : Project 25 Standard.
AP25 system is a 9600 baud CC and a Mot II or mixed mode is 3600 baud CC. If you program it as a P25 your telling the scanner it's 9600 baud when the system you had was 3600 baud.

Any system listed as Analog and Common Air Interface is a 3600 baud system. All 9600 baud systems are completely digital. This does lead to some confusion at first.
