looks like they are using CC8 on their channels. I have only heard talk group 35 talking for a brief period and it was encrypted.

what is RAS?

I use SDRSharp and DSD+ to decode these types of systems.

RAS is Restricted Access to System, means you have to have some obscure very long key to get into the system, basically means its unhackable, and even if you did get into the system it seems to be encrypted...

RAS is an acronym for Restricted Access to System. It prevents unauthorized radios on a DMR / Cap+ system. Similar intent that a System Key has for SN/SZ/P25 systems.

RAS keys can be up to 24 characters containing: 0–9, A–Z, a–z, hyphen, underscore, dollar and pound.

The SK on SN/SZ/P25 systems is the announced System ID and you need the key (a physical file) to program the subscriber. The RAS key is a security measure to prevent rogue radios on systems that lack centralized controlling and authentication (Con+ for example); basically an encryption key for system access.

the system is pretty busy! Here is what i was able to figure out this morning.

the channel order is as follows:
R1 - 464.575
R2 - 464.425
R3 - 464.775
R4 - 464.925
All use CC 8.
they are using RAS.

Talkgroups:
23 - Custodians
27 - Electricians
29 - unknown
31 - grounds keepers
35 - Encrypted
41 - unknown
47 - plumbers

I will post more when I figure it out.
