Provoice

[cutcat]

I am new to scanning and came across an area that the trunking system used provoice. The comments were that no scanner can monitor this type of system. Can anyone explain this to me. I have a Uniden BCD396T with the most recent firmware.

It's a special type of signal processing, and is proprietary. No scanner can receive it, and none ever will.

Tyco the company who owns M/A-Com the company who makes and designs EDACS trunked radio systems has their own brand of DIGITAL called PROVOICE. And by law they are NOT required to share that format with any other radio system.

They choose NOT to provide or allow scanner manufactures to duplicate their digital format (provoice) in their scanners. To do so is a violation of the law. They have publicly said they never plan to release it to anyone. Just like Motorola won't release iDEN digital format. iDEN is used in Nextel.

And that is why you'll never be able to listen to a provoice transmission EVER! with a scanner.

Not at all...

Nothing requires new systems to be APCO P25 either.

To clarify, whether or not an agency is required to buy APCO P25 depends on their intended funding sources. At least some types of Federal funding require P25 compliance.

As Dave said funding from the Feds may require the system to be P25 compliant.

Right. If you don't want P25, then you don't go with a funding source that requires it. Go your own and you can LTR, OpenSky or anything else.

You will have to buy an actual EDACS radio with Opt.29 enabled (Pro Voice) and then have it programmed. But be sure to know if it is encrypted Pro Voice because you'll be wasting your money if it is.
