Currently the some of the main issues with the move to 800 MHz for communications are: |
1. | Excessive "bonking" (dropped communication link with the towers); |
2. | Poor or completely failed communications through metal sided buildings; |
3. | Inability to scan both UHF and VHF frequencies with pagers and portable transceivers; |
4. | Confusion regarding which frequency mode (UHF or VHF) should be used; |
5. | Some neighboring (mutual aid) departments do not use 800 MHz; |
6. | Inability to be paged over VHF when the 800 MHz system fails. |
August, 2016 At a considerable expense to our townships, Nottawa-Sherman Fire Department went to 800 MHz paging and 800 MHz command radios.* All Isabella County fire service 800 MHz communications took place on the frequency desgnated as 37COM, including the paging for NSFD personnel. All NSFD pagers were programmed to receive the 800 MHz 37COM frequency. With
their pagers, NSFD personnel could hear all 800 MHz radio traffic
between dispatch, ambulance crews fire officers and other fire
department vehicles. Update: The problem described below was resolved by Chief Livermore early in November, 2017 with the purchase of software capable of programming our pagers. August, 2017 Central Dispatch-911 Director Marc Griffis mandated a change in
frequency for all 800 MHz traffic between Central Dispatch and Isabella
County fire department units and personnel. This action, once again, endangered Nottawa-Sherman Fire Department personnel. The new frequency, designated 37FE911, could not be received by Nottawa-Sherman 800 MHz pagers without reprogramming all 24 units at a substantial cost to our townships. All non-officer NSFD personnel had only their pagers for listening to 800 MHz traffic. WE NO LONGER COULD HEAR: 800 MHz radio traffic between
We could not hear which of our trucks had checked en route. We could not hear if an
ambulance had checked en route. We could not hear the ambulance announce their location. We could not hear if additional resources had been dispatched or were needed. Most
critical, we could not hear safety related information transmitted by Central Dispatch (e.g., dangerous scene condtions, road closures). November, 2017
