Splinter only applies to frequencies between 851 and 866MHz. So in reality all 800 systems would be configured for splinter. If the South Zone began to use freqs below 866MHz (highly unlikely given rebanding) the system would need to be set as Splinter in the scanner's configuration. So it's a good ...

I would imagine since it's just 0s and 1s rearranged differently, encryption of digital audio should have the same audio quality as non-encrypted digital audio ... Orange County law enforcement has been running full-time encrypted P25 for years now. Exactly. With analog SecureNet there's a double c...

Other days, it may be 5008 that's 'primary' and the actual on-air talkgroup. As a result, a scanner listener who wants to receive all the dispatches must have all three groups entered into the scanner.

The encryption on digital sysstems makes the audio even harder to understand that the normal digital, so many agencies use it sparingly, if at all. This is incorrect with P25 digital voice. It is true with analog encryption, which is known as SecureNet and is characterized by what sounds like open ...

Re: Latest Trunker Listing of active SD TRS Talkgroups

0 God (System Operations) This TG ID appears due to an attempt to affiliate on the dynamic regroup channel. In RCS radios this is called "REWARD". Since the channel is dynamic it is only populated with a working TG ID when the system (via console) has sent a TG to the radio. So outside of...

Well thats the ones I know for sure. But yeah skip is right any TG on Any zone is possible. A part of every wide-area SmartZone system with many different agencies is proper management of the TGs.

A zone is comprised of multiple sites in a networked trunked system which all operate in parallel with the same frequencies. This subsystem is considered either simulcast or receiver voting. It's meant to cover the North East part of the County and slightly north. You may be able to, though intermit...
