If you’re configuring a radio for a trunked statewide network, one of the terms that you might be familiar with is a WACN or a Wide Area Communication Network number and a system ID..

What is the difference between digital and trunking scanners?
What is the main difference between digital trunking and trunking. Trunking is a method of sharing frequencies to accomodate greater traffic. Digital (trunking or conventional) is a form of modulation, i.e. the way the signal is made to carry voice or other intelligence.
What does trunking mean?
Trunking is a technique used in data communications transmission systems to provide many users with access to a network by sharing multiple lines or frequencies. As the name implies, the system is like a tree with one trunk and many branches.
What is a trunking frequency?
A trunked radio system is a digital two-way radio system that uses a digital control channel to automatically assign frequency channels to groups of users. … Instead of assigning a radio channel to one particular user group at a time, users are instead assigned to a logical grouping, a “talkgroup”.
What does triple trunking mean?
Jan 4, 2010. The Triple Trunking was a catch phrase used for RadioShack scanners, and as correctly mentioned earlier in this thread, indicates the scanner works on LTR, Moto and EDACS systems. Newer digital scanners were called “Digital Trunking”.

How does a trunking scanner work?
This is exactly how a trunked radio system works: All users are in one queue and get assigned the next available channel. Instead of having a separate frequency for the FD, one for the PD and another for the ambulance, they just go to the next channel that isn’t being used.
Do I need a trunking scanner?
Even then trunking is only used in larger cities. Thus, if you want to use the scanner for listening to other than railroads, consider a trunking scanner. Otherwise, you don’t need it, nor do you need a digital radio, for that matter.

What does site trunking mean?
SITE TRUNKING is a safeguard operating mode common to trunked, multi-site radio system such as the IPSC Statewide 800 MHz system. … However, when T-1 connectivity is broken, the particular site is no longer able to communicate with the system and the other sites on the system. This condition is known as Site Trunking.
What does dual trunking mean?
Multi, Dual, Triple, … Dual trunking SHOULD mean that it can track two separate trunks at the same time.
Do analog police scanners still work?
These scanners are obsolete primarily due to the fact that over the past few years, more and more public safety agencies have been transitioning towards operating on trunked and digital radio systems making some of these older analog scanners obsolete.
Can a digital scanner pick up analog?
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. … If this is the system your local agencies use, you’ll need a scanner with trunk-tracking capabilities.
How do you use scanner frequencies?
Put the scanner in manual programming mode.After you hit “Manual,” enter the channel number you wish to use, followed by “Manual” again.Alternately, if you do not have a list of frequencies or just want to explore a bit, you can hit the “SCAN” button and the scanner will scan available frequencies.
