Trunking

[Seanm214]

How is it possible to scan police Trunking p25 system without the system key. Since radio reference doesn’t provide the system key then how would it be possible to scan trunked radio on a radio like an xts5000 or another radio like that? Do people just program all frequencies in the system and scan them?Also what is the definition of a prototype radio?

In all honesty, Trunking is a very complex process of programming for a beginner to a moderate hobbyist. The only way you’re going to get the system key is from the admin of the trunking system that you’re looking to monitor, or by using illegal tools which are not to be spoken about on here. If you want to be able to hear some traffic WITHOUT the system key, and WITHOUT possibly tampering with the system because of poor programming, I’d just put all the voice channels in a conventional scan list. You won’t be able to follow the conversations all the time if it’s a busy site or busy system, but you’ll be able to hear some good stuff. On another note, I’d suggest studying the ElroyJetson non-affiliate trunking method and eventually go from there.

If you are going to use a Motorola 9600 bps trunking radio to scan (non-affiliate method) a Motorola system, you must have the system key. Just how the radios work. Now you can perform a conventional scan of the trunking channels with the conventional TG settings set but it is complex and limited to systems with 15 channels or fewer but if you are going over that the conventional method simply won't work.

If you don't have the system key...honestly better off with scanner as with Astro 25 subscribers you are also limited to only 10 groups in a scanlist in trunking operation.

A system key is used to enable the trunking parameters in CPS. Master System keys are produced by the manufacturer(Motorola in the case of the XTS series) and are given to the system operator. With out a system key, you can not set the trunking parameters. Period.

System keys are used to keep unauthorized folks(you, me and anyone else the system operator does not want programming radios to operate on their network)from programming trunking radios on their network.

Please just buy a scanner or unication pager. Your lack of understanding of what a system key does, and where you get a system key, demonstrates you do not have the skills or knowledge to be messing with a subscriber radio to listen to a trunking system.

Okay I will buy a scanner can you recommend any good digital scanners?

Okay can you recommend any good digital trunking scanners?

Here is a listing of current model scanners:

Uniden Scanners - The RadioReference Wiki

wiki.radioreference.com

The new SDS models are hands-down the best, especially in Simulcast areas.

The 996P2 and 326P2 are two Phase II scanners I recommend, if you are on a budget or are not in an area that suffers from Simulcast Distortion..

SDS series from Uniden or a Unication that supports P25 phase 2 trunking.

Thank you.

Since the OP has decided on a scanner I think we're done here.
