NEXTEL Radio?

Ok, I'm uinderstanding the system more and more as I work with it. I tried using PTT to connect to the hospital and was really confused when it wouldn't work. I told the medic that it wouldn't work and he thought I was doing it right so we showed up on the hospital doorstep w/o prior notice.. I learned they are not happy about that. Later found out that you have to make a phone call to get the hospital--which wasn't much better, their phone just kept ringing!

The one issue I have is being able to hear the trans'm clearly when on the PTT feature. It seems really static-y when I'm getting messages from dispatch, even more so than a traditional motorola radio system, anyone know why?

It shouldn't be static-y at all. Its a digital signal and when it degrades you will get garbled audio not static. Makes me think that something isn't setup right a dispatch or the person isn't taking properly into the mic. Is the system in the ambulance setup to broadcast over the radio speakers?

Also as far as hurricanes go, we try to use generators where we can. When they run out of gas we take them and gas them up, we have people for this. The sites stay up until we get back with gas. During Katrina we had to buy gas and put big tanks on pickup trucks to get out to sites, it worked well. Also for transport we microwave that in.
 
that was my thought--that since it a digital signal i shouldn't be getting that much static, but I for some reason, get a lot of noise that sounds like static that I'm almost always guessing at what was said. Calling to the hospitals i get clear audio, but when i speakerphone it i get some "static" but not nearly as much as when i'm PTT-ing with dispatch, the EMS cars (supervisor cars) or other units.

Sometimes it can sound like static, if someone is taking to closely to the microphone on the phone itself. I see many people who think they must put it right up to their mouth for it to function right. You can actually hold it 5 or 6 inches away and it do fine. I don't know if you use the handheld radio, or if you have a setup in your vehicle where you use a handheld microphone like truck drivers use.

Do you just hear the static type noise when talking to dispatch, or do you hear it when you talk to everyone.

Just with dispatch, they use a stationary phone and are normally 2-3 feet away from it, it looks like a dispatcher's radio stand and has a horizontal push to talk button on the stand that they press down (toward the table it sits on) to transmit.

I hold it 2-3 inches from my mouth as that what we were taught in EMT school when transmitting. When calling hospitals, no static, but when on speaker then there is static.

We have the big radio like phones, no setup in the vehicle, portables only.
 
Sometimes just changing the volume... or going to the earphone makes a big difference. Give it a try.
 
Yeah 2-3 inches is fine, maybe 5 or 6 inches was exaggerating it some. When u say talking to hospital no static, talking to dispatcher on speaker static. Do you mean that you have the DC speaker phone muted and hold the phone up to your ear to hear the audio?

No, i usually keep the DC on speaker.

But for example, when we get a call to a nursing home, I usually can guess which one, but its hard to tell. Today, We got a call to a private residence and while i could make out the numbers, even after 3 tries my partner and I had to call up dispatch using the phone call function of the phone to understand what the street name was for the call.
 
Try putting the DC on the earpiece...it sometimes helps.
 
Actually, turning the volume down seems to help a bit. Also, calling in via phone can help as well, but I don't like to use that since it requires a lot more coordination to use.

Some of my partners will call on their personal cell phones when they think something will be transmitted that is personal that they don't want other people around to hear, but until my company issues me a cell phone and requests that I use it instead of DC, I will still use the DC feature on the radio. I figure, its nothing that someone using a regular radio wouldn't hear anyway and its not my job to use my personal equipment for company functions.
