Apco with non digital scanner

[fallinsouth]

I have a question about scanning APCO.

Can the voice from a APCO system be heard with convential trunk scanner in manual mode,

Say for example I just want to start gathering freqs that are not in the database, can my convention scanner find them but just not scan them, or will I have to get a digital scanner to do anything with an APCO system.

I'm saving for a 996t but it might take a little while to get one, in the mean time I wanted to be tracking freqs, so I can be ready when I get it.

If you mean APCO 25 digital modulation, then you can't listen to it without something to decode the digital.
There are many older APCO standards that were not digital. There is a lot of non-trunked digital stuff out there too, but at any rate you need a receiver that is capable of demodulating digital to listen to it.

You will hear something, but it will just be unintelligible garbage. (raw apco25 modulation)

This maybe a question for another thread, but are all Motorola Astro's APCO-25 / dual mode that can transmit conventional and digital.

Also if you have a radio in front of you is there a code/button that will show the freq that you are operating on?

Ok I already asnswered my dual mode question.
Still don't know about the freq display

NO

Commercial equipment is about "Channels", "TalkGroups" and/or "Modes".
The user does not usually KNOW or CARE what frequency he is on.

Are you talking about the display on a scanner or on an actual APCO-25 radio? As N Jay said, the radio will not show the frequency because the user only cares about which talkgroup they are using, not what frequency they are actually transmitting/receiving on. A scanner will show you the frequency. I have a 396, while scanning/searching it shows the frequency of the control channel being monitored, while receiving a transmission, it shows the frequency of the voice channel that is being received, as well as the talkgroup's ID number or alpha tag if one is programmed.
