Hawaii County Public Safety System: New Digital Radio System (P25 Phase 2 TDMA) that Hawaii Police, Fire, and Civil Defense departments switch to in March 2017. The old analog system has since been phased out and is currently fine-tuning this new system and enabling the many capabilities this system has over the old system. This also leads way for other county departments: DWS, Public Works, Solid Waste, and other county departments to make the switch as well. Analog Scanner users were greatly affected as their scanners went silent and to those who had new digital scanners capable of decoding this system were not affected if they were programmed correctly.

State of Hawaii Medicom System: This communication system is used primarily by Hawaii Fire Department EMS for Ambulance to Hospital communications to base station doctors or nurses about incoming patients to there facilities or requesting advice on a patient. This system still runs on a conventional system apart from County's Public Safety System and is funded and maintained by the State of Hawaii. State of Hawaii Medicom System P25 Phase 1 system conversion was completed in March of 2018 and in the near future and with the possibility of encryption to protect the privacy of patients under EMS care. (We will update this page once it occurs) 

 

Still capable of being heard on an analog scanner (APCO P25 Phase 1 Capable), but eventually being silenced once upgrades to the new system are complete. 

 

State of Hawaii Airports: Communications currently at both Hilo and Kona International Airports currently run under the Project 25 system (P25 Phase 1 system). It's a mixture of Conventional and Digital voice channels similar to how a phase 2 system works. Currently, each airport system runs under a simulcast system under one assigned central tower location on Airport property, allowing for full coverage around the entire airport property. Primarily used only by Airport Police currently, are underway to update the system to include other airport divisions in the future, thus allowing for all divisions to be patched on one channel for joint communications during an emergency.

State of Hawaii Sheriff Division: Communications for all State Sheriffs operate under a Project 25 system (P25 System Phase 1) with a mixture of conventional and digital voice channels, that run similar to how a Phase 2 system works. Currently, the Sheriff Division, operate under a conventional system that still can be heard with analog scanners compatible with phase 1 systems. 

 

Hawaii Island Businesses: Most businesses still operate under analog systems and few businesses have switched to a digital/conventional system since 2010. Most businesses operate low-power radios (similar to consumer 2-way radios) and can be heard on analog scanners.

State of Hawaii Operations: Communication operations vary by department and agency. Currently, most departments still run on an analog system and eventually merging to the Hawaii Islands Region Interoperability Network (a P25 Phase 1 system) in the near future. No timeline on when that will happen, but only a handful of agencies have been integrated into the system and currently using it.

Federal Agencies on Hawaii Island: Hawaii Volcanoes National Park, Pu'uhonua O Honaunau, Pu'uokala Heiau National Historic Park, Kaloko-Honokohau Historical National Park, and Pohakuloa Training Area are the federal agencies on Hawaii Island, they operate on a mix of APCO P25 Phase 1 and Phase 2 system and analog systems. It varies by department/agencies within the federal system, eventually, all agencies will integrate onto a Statewide Federal Radio system that currently operates on APCO Phase 1 system with upgrading to Phase 2 coming in the next few years.
