9/23/15 - Air to Ground Communications
Please use Med A/Med 10 only for all helicopter communications.
Several helicopters that serve our area have 800 MHz capability.
Additionally, and as far as we know, all area helicopters have access to Med 10. Med 10* and Med A are hard patched together, and will remain so. This hard patch enables both air and ground ambulances with Med 10 capability to talk to users of our 800 MHz system on Med A, and vice versa.
When requesting a helicopter, dispatchers can advise the flight center of the radio frequency that will be used (Med 10 base).
* Med 10 means the base frequency or 462.975 MHz, PL 173.8. It is not Med 10 Direct.
