****4. I have about 10 frequencies listed for Ruth EMA. Are these used daily, or just in case of emergency situations?
You're probably refferring to North Net, South Net, Firecom (for VFD's), no?
Also, note that the Rutherford County Highway Department and North Net share the same frequency, but different PLs.
I haven't heard of *ten* frequencies listed for EMA. They may have base station licenses for all the fire mutual aid, statewide EMS and HEAR channels.
Post what you have listed and I can check on it (possibly).
****1. When EMS dispatches ambulances, they first send out audible tones. I'm guessing pager tones, but i know close to nothing about this subject. Is there a way to decode/understand these tones? What exactly are they used for?
If you are referring to the two tones you hear, yes, those are the paging tones (Motorola QCII). The 'telephone' tone is a ring back tone to let the dispatcher know that the page was received by the medic's ambulance radio.
There's no way to understand them unless you memorized the sound of them associated with a particular unit (hi hi hi).
****The Rutherford County Ambulance Service is a screwy service that insists on some quarky proceedures. MFD is dispatched on the MFD frequency. They check enroute with MFD and then they check enroute with RCAS on the EMS frequency. This allows the control of the response do reside with RCAS.
I wouldn't say screwy. . .just a separate entity falling under a different government. That's why the system is the way it is. . .
