What is a trunking scanner?
Since a trunking system might send its call and response on different frequencies, a “Trunking” or “Trunk-tracking” scanner is needed. These scanners will let you monitor the control channel frequency as part of the TalkGroup so you can hear both calls and responses and more easily follow conversations.
Can you scan trunked radio systems?
Scanning. Most scanners that can listen to trunked radio systems (called trunk tracking) are able to scan and store individual talkgroups just as if they were frequencies. The difference in this case is that the groups are assigned to a certain bank in which the trunked system is programmed.
How does a trunked radio work?
When a trunked radio user wishes to communicate with another user or group, the computer automatically assigns them the first free available channel to make each call. The underlying principle of trunking is that not all users or groups who need to communicate in a channel will do so at the same time.
What is a dual trunking scanner?
From The RadioReference Wiki The Pro 95 is a dual trunking handheld scanner designed by GRE and sold by Radio Shack. It features the ability to track both conventional and trunked radio systems at the same time. It will follow Motorola type I and II systems, as well as EDACS trunked radio systems.
Should I get a digital or analog scanner?
Analog: Smaller agencies may still be using analog, so an analog scanner might be okay for your needs. Digital: If you get more into it, you’ll want to upgrade to a digital scanner because most digital scanners can pick up both analog and digital signals.
What is P25 trunking?
The P25 trunking is a separate channel that is designated as the control resource and is different from the traffic channel in that it functions as a resource allocation and digital communication message bearer and handler between the RFSS (RF Sub-System) and the SU (Subscriber Unit).
What is the biggest benefit of a trunking system over a conventional one?
Unlike conventional radios, trunked networks do not have user channel selection. Instead, a central system dynamically assigns channels to users by group. This is a more efficient use of the available spectrum, a simplification of the user experience, and an improvement in security.
How does a trunking scanner work?
A trunking scanner works differently than conventional radio systems. In an standard system, channels are designated and assigned to totally different functions and departments. A discussion picked up by the scanner can be matched to the right department if you recognize the talkgroup ID’s of each.
What are the different types of trunking systems?
There are several types of trunking systems but they all work in much the same way. There are differences in the way they get programmed into scanners as well. The main types of trunked systems in use by Public Safety agencies in the USA include Motorola, EDACS, LTR, APCO25 Phase 1 and APCO25 Phase 2.
Do I need a trunking scanner for my home?
Depending on where you live, a trunking scanner (as opposed to a traditional police scanner) could be needed to hear fire and police communications. With a trunking scanner, you’ll continually recognize what is occurring around you.
What is a trunked system?
The main types of trunked systems in use by Public Safety agencies in the USA include Motorola, EDACS, LTR, APCO25 Phase 1 and APCO25 Phase 2. For scanner listeners these trunked systems add a layer of complexity to the programming. Depending on the type of scanner and the type of trunked system the method used to program differs.
