Was listening to Poway/Rural today and several times they went to emergency traffic and with that came a emergency tone during the emergency traffic. Did SDSO give in to having a tone with ET?

Not so much as 'giving in' as much as the new dispatch consoles are installed. The department has wanted it for some time.

The New consoles will also allow using the Tac3 Channels (30Tac3, etc) and encryption on those channels as needed.

What consoles are you installing?

Our county was supposed to get new Motorola consoles but they got damaged by water in Houston during the hurricanes last year so we are delayed until late fall.

A couple of weeks ago, I heard several agency over night, doing the full range of alert tones testing on secondary talkgroups. So many beeps and tones available.

Are we still going to have the same north/south/east split simulcast cells we have now with the upgraded RCS? Aka if I'm working in North County, will I only be able to hear talk groups on the north?

Operationally, yes.


The North simulcast will be split into two simulcasts ("North" of 78, and "West" south of 78) but generally traffic will not be split.


That said, a Del Mar - only talkgroup would not be enabled in the new North cell - only the west.

The proper name for the feature is "Channel Marker".

SDSO had this feature decades ago on the UHF 453MHz system. It was a DTMF-based device that produced a rapid series of DTMF "0" tones to indicate there was emergency traffic in progress.

Unfortunately SDSO lost that capability when things migrated to the RCS, as the channel marker was not a supported feature in SmartZone 3.0. When the system was upgraded to 4.1 and beyond, they *could* have brought it back, but apparently they elected to bring it back with the move to MCC 7500.

San Diego Police had the same thing on their SmartNET system, the difference being they used DTMF "9". They were able to have this on a trunked system as a "Special Product", it was not standard feature and was custom-built for them. When they migrated to SmartZone 4.1, they lost the DTMF channel marker and began using the channel marker integrated into Centracom Gold Elite (since upgraded to MCC 7500), which is the single tone.

There is everything you never wanted to know about channel markers in San Diego County.
