System Notes

This wide area MPT-1327 system - currently under construction - will eventually contain approximately 100+ sites and serve both PG&E Gas and Electric operations. Each site has its own hexidecimal "system ID", and all sites are networked together to allow users seamless roaming through PG&E's entire coverage area. Mobile registrations are required at the site in order to make it broadcast specific talkgroups.

The Base frequencies and Step sizes are below, which should be complete, and will serve to calculate most of the channels.

Ranges	Start	End	Spacing	PL
000-161	451.000000	453.012500	12.5kHz	196.6
162-213	454.018750	454.656250	12.5kHz	196.6
214-364	460.650000	462.525000	12.5kHz	196.6
365-510	463.200000	465.012500	12.5kHz	196.6
511-672	451.000000	453.012500	12.5kHz	199.5
673-724	454.018750	454.656250	12.5kHz	199.5
725-875	460.650000	462.525000	12.5kHz	199.5
876-1019	463.200000	465.012500	12.5kHz	199.5

Each site's hexadecimal sysid is a make-up of several MPT network identifiers. Below both Zone and Site # are shown. Each site - unless noted on the site's page - uses a CTCSS tone of 196.6. Some sites have been known to change to 199.5 and update their channel ID accordingly (see table).
