It has been a while since any updates on the new radio system for the fire department so I will try bring you guys up to date on what’s going on.
Two operational zones have been moved and most have been renamed. What was known as zones 8 and 82 (now 8G and 8H) has been moved and will not be used as normal day to day operational zones. Zones 80, 81 and 83 (now 8A, B, and C) will be the day to day operational zones.
The narrow band VHF channel (155.685) that will simulcast fire dispatch is scheduled to be operational on Friday. Simulcast between the old 490 system and the new TDMA system is scheduled to start on Monday. The simulcast setup is:
Old channel 1 is new channel 1 in all zones
Old channel 2 is new channel 2 in all zones
Old channel 3 is new zone C channel 3
Old channel 4 is new zone A channel 4
Old channel 7 is new zone C channel 7
Old channel 8 is new zone A & C channel 8
Old channel 9 is new zone A channel 9
Old channel 10 is new zone A channel 11 (not a typo)
This might help id some of the talk groups.
They will start installing the mobiles towards the end of the month and that is expected to take about 3 months to complete. Portables are expected after the mobiles are installed and complete system changeover will be after the portables are issued.
And to dispel some of the rumors going around about the system being FDMA for fire, not true. It will always be TDMA unless an out of county unit affiliates with the system and then the talk group that the unit is on will go to FDMA until it leaves the system.
I will try to get a copy of the new new zone map on the Wiki page in a couple of days.
