title: Helicopter emergency medical service scene communications made easy.
abstract: Narrowbanding has caused numerous communication issues. The solution is to use a mutual aid frequency like 123.025. That frequency is 155.3400, and every helicopter emergency medical service operator and emergency medical service agency should name this frequency as "EMS [Emergency Medical Services] Mutual Aid" and preset this frequency for all helicopter emergency medical service scene operations.
