I see new talk groups have been added to Regional Wireless Cooperative (RWC) for phoenix fire, when will phoenix start using these new talk groups does anyone know?
Phoenix, and other suburban fire services, only uses those TGs for non-hazard incidents (a la medical emergencies). Back when the RWC was in development, it was expected that all departments would join. Well, lo and behold,Phoenix Fire found that the new network doesn’t suit their needs in the hazard zone (basically an incident where FFs suit up), so it was decided that the network will only be used for non-hazard calls being some 75-80% of their call volume.
As John said, the K2-K5 are used for admin, prevention, training, etc. K4 and K5 are also encrypted. K6-9 are for medical responses, while K10-14 are for major ops (a la mountain/water rescues).
