Systems in Maui County


There is a wide variety of different systems being used in Maui County (Comprised of Maui, Lanā'i, and Mōlokā'i) and many of you are trying to figure what does each system mean for the public. Here's a list of the different systems used in Maui County and how is that going to affect the everyday scanner hobbyist and the general public.

Maui County Public Safety System: New P25 Phase 2 - 700 MHz Simulcast system went online in early 2017 replacing an existing conventional system previously in use by all Maui County systems. All Agencies including Fire, Police, EMS, Ocean Safety, and All-County Divisions made the switch allowing them to improve radio communications between all islands.

State of Hawaii Medicom System: This communication system is used primarily by American Medical Response (Contracted by County of Maui) for Ambulance to Hospital communications to base station doctors or nurses about incoming patients to their 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 is currently underway and is expected to be online by end of 2018 or early 2019 (We will update this page once it occurs) 


Still capable of being heard on an analog scanner, but eventually being silenced once upgrades to the new system are complete. 


State of Hawaii Airports: Communications currently at Kahului International Airport 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.

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 State of Hawaii Sheriff Divisionstill operates under a conventional system that still can be heard with analog scanners compatible with phase 1 systems. 


Maui County 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.
