Default Southern California Edison

I have noticed that when monitoring Edison's system the dispatchers have a "digital" sound to their voices. Field units sound analog.....are they changing over to digital soon?

Back in December, I briefly monitored a P25 system on 938.8250 and the sysID (BEE00-5AA) came back to Edison. Sounds to me like that is what you are hearing.

Thanks.....Let me check that frequency. It's not coming up P25 on my scanner, but it sure sounds like it.

Starman, Is Edison worth listening to ? I was thinking about adding this TRS to my software...but was wondering if its worth the work to enter it all. lost R.S.O. Jan so could fill my old bank.

Your thoughts,
Scott

Hi Scott, Edison is one of my "I've got to get a life" systems that I monitor, along with the Dollar Tree Distribution Center. My son works for Edison so I hear him sometimes and I've heard them working outages close to home. To each his own. Give it a try. Tom

I checked it again today. There wasn't any activity observed, but it does come up as a P25 TRS. I can't recall how I figured out it was SCE, though.

The underground vault that serves my neighborhood blows 3 or 4 times a year. Every time it does blows, power is out for at least 2 hours so I find it worthwhile to keep SCE programmed in my radio. It's nice knowing if I need to purchase additional batteries or ice.

I wouldn't keep wondering.

Due to obsolescence / lack of parts availability, Motorola SmartNet / SmartZone systems around the country have been upgrading their core switches to P25 while keeping the 3600 baud site infrastructure. When this happens, the dispatcher audio from connected consoles goes through a digital gateway (there is no analog audio through a P25 core) giving it the 'digitized' effect and sound. A new system ID is also assigned, although usually the 3600 baud infrastructure still broadcasts the original system ID.
