Found some new VHF frequencies licensed to Sarnia Fire with P25 emission designations. Got digging a little more and came across this...
Partner with Sarnia Police Services (SPS) on their public-safety grade voice radio infrastructure. The SPS project involves upgraded infrastructure such as towers, transmitters & receivers, and interface with dispatch consoles. This infrastructure has capacity to add a separate Fire system to provide for the critical emergency and non-emergency communications needs of Sarnia Fire Rescue.
The Sarnia Fire Rescue potion of the project would have three phases:
1)feasibility study and technical specifications/infrastructure prep in 2020,
2)purchase and install new station, mobile, and portable radios and accessories in 2021, and
3)purchase and install new site transmitters/receivers and dispatch radios in 2022.
The Project 25 (P25) is a set of standards for digital mobile radio communications designed for public safety use. This technology will allow Sarnia Fire Rescue to have:
•Shared governance and control with SPS over maintenance, performance, and operation;
•Interoperability (direct radio communications) with police and industry;
•Encrypted communications;
•New portable radios which are intrinsically safe and have a prominent emergency activation button;
•Broader coverage area with fewer dead zones; and
•97% in-building coverage for firefighter safety.
Meets National Fire Protection Association (NFPA) 1802: Standard on Personal Portable (Hand-Held) Two-Way Radio Communications Devices for Use by Emergency Services Personnel in the Hazard Zone and Occupational Health & Safety Act Section 21 Guidance Note 2-3 Radio Communications.[\quote]
Hopefully the encryption is just for interop with Sarnia Police.... Buuuuut I wouldn't hold my breath.
