How do I program the PG & E MPT-1327 Standard frequencies in to my SDS 100?

[kf6olc]

Unusual question. How do I program the PG &E MPT-1327 Standard frequencies in to my SDS 100? I have currently programmed in my SDS 100 for PGE.

San Mateo County PGE 153.560 Mhz
San Francisco County PGE 153.650 Mhz
Santa Clara County PGE 153.545 & 153.590 Mhz
Santa Cruz County PGE 153.635 Mhz
Alameda County PGE 158.130 & 158.235 Mhz
Contra Costa County PGE 153.080 & 153.485 Mhz
Solano County PGE 153.725 & 158.205 Mhz
Napa County PGE 158.205 Mhz
Sonoma County PGE 158.190 Mhz
Marin County PGE 158.265 Mhz
The Area wide PGE Freq 153.575 Mhz

I would like to add Pacific Gas and Electric (PG&E) Trunking System, Various, California

I don't see the frequencies in the Uniden Sentinel. I just need some guidance. Thanks for any help.

I don't see MPT-1327 as a system it can decode on the specifications page for the SDS100. IIRC it's an analog format, so you could probably just scan the frequencies conventionally, but that would not allow you to track a conversation very well.

No scanner can trunk track MPT-1327 & this is why it does not appear in Sentinel. Since the emissions are analog the frequencies can be programmed conventionally. See list of software decoders here

I might be wrong, but for the most part when I’ve listened, one repeater will hang open for the entirely of a conversation, after which some time lapses and the repeater drops and goes back into the trunk pool.

The local MPT-1327 systems near me are easy to monitor because the control channels rarely move. As @Whiskey3JMC suggested, you can monitor the analog voice channels with your scanner.

If you are comfortable using RTL-SDRs, give SDRTrunk a try. SDRTrunk decodes MPT-1327 systems perfectly.

yeah, the PGE system seems to have two hang times on the repeaters, about 10-15seconds after a transmission for a normal talk group PTT, and then there can be a good 60-120 second hang time for private calls from radio to radio. I've never personally decoded audio with the SDR Trunk, just the metadata, but you can follow the call data with SDR, and then use a scanner to listen to the audio.

This. MPT-1327 is a very old type of trunking system, and therefore they’re likely to stay put on the same frequency for the duration of a conversation just due to the long repeater hang time.

Without talkgroup IDs you won’t necessarily know who is talking, but if you pay attention to addresses and unit IDs that should be good enough.

Few months ago I heard radio checks on their VHF sounded like it was repeated.
