UniTrunker supports control channel monitoring for the following trunking types:
- EDACS Standard 9600 Baud and Narrow 4800 baud (Normal, ESK and Site Pro / Extended Addressing)
- LTR (with supporting radio)
- Motorola Type I
- Motorola Type II (SmartNet / SmartZone / OmniLink)
- Motorola Type IIi Hybrid
- Project 25 9600 bps
- MPT-1327 systems
UniTrunker also supports downloading system information from the RadioReference.com Web Service.
UniTrunker cannot monitor or decode conventional P25 data or audio.
Support can be found on the Trunking decoders forum
What Can UniTrunker Display?
- Basic system information - system type, system id, talkgroups, and radio ids.
- Basic site information - site or cell number, and list of channels.
- Site call activity - who's talking, on what channel, and to whom.
- Neighboring Site information - list adjacent cell or sites with control channels.
- User roaming - what radios are registed to a particular site.
- User affiliation - what talkgroup a user has requested.
- Patches - a dispatcher initiated action that joins two or more talkgroups together.
This program replaces a previous generation of UniTrunker (Retro).
Public Alpha - released October 2008 (Version 18.104.22.168)
What are the Call Types available?
Colum "T" = "Type" which would be [G]roup or [I]individual (iCall)
Colum "CT" = "Call Type" - See below
For EDACS systems:
Fon - Telephone call
Tst - LCN tester
Dat - Data call
Ana - Analog Voice Call
Emg - Emergency Analog Voice Call
Dig - Digital (ProVoice or Aegis) Voice Call
EmD - Emergency Digital Voice Call
(Note that these follow the TG+n values in order.)
(none) - Analog voice call
All - All talkgroup (analog)
Em - Emergency (analog)
XP - Crosspatch (analog)
EXP - Emergency Cross Patch (analog)
EMS - Emergency Multiselect (analog)
? - Reserved
MS - Multi Select (analog)
Dig - Digital voice call
DAT - Digital All Talkgroup
DEm - Digital Emergency
DXP - Digital Crosspatch
DEX - Digital Emergency Crosspatch
DEM - Digital Emergency Multiselect
? - Reserved
DMS - Digital Multi-select
For P25 systems:
P25 call type is the call's priority - a single digit from 1 to 7. "4" is the default normal priority.
Emergency calls prefix this digit with the letter "E".
Frequently Asked Questions
Q: Do I need a radio with discriminator tap?
A: The short answer - Yes. The long answer - You may be able to decode 3600 baud Motorola control channels with a 50-70% decode rate without a discriminator tap. This is totally dependent upon the scanner/receiver and sound card you are using. You will not be able to decode EDACS, or APCO Project 25 without a discriminator tap. MPT1327 is the exception. It generally decodes equally well with speaker audio or discriminator audio. With the GRE PSR-500 and PSR-600 as well as the Radio Shack Pro-106 and Pro-197 you do not need a discriminator tap; the program reads through a USB cable attached to the radios' PC/IF port. UniTrunker has support for EDACS, Motorola and P25 systems with the PSR500/600 and the Pro-106/197.
Q: Do I need a slicer?
Q: Will this work on Windows? If so, what version?
A: Yes - Windows 95 (with IE4 or later), Windows 98, ME, 2K, and XP (all flavors).
Q: What types of trunked radio systems can I monitor?
A: APCO Project 25, EDACS, LTR (with supported radio), Motorola, and MPT1327.
Q: How can I use this to listen to calls on a trunked radio system?
A: You need a second radio that accepts computer control to tune to voice calls as they occur.
Q: Does the program permit downloading talkgroup information from the RadioReference.com Web Service?
A: Yes - you can download Motorola and APCO P25 systems by trunking system ID. You can download EDACS by looking up the RR DB SID (that's the ID # assigned by the database to each trunked system). You must be a paid member with a valid user id for this feature.
Q: Can I import my trunker data files?
A: Yes - read the Hints section of the documentation that describes how to do this.
Q: How much does it cost?
A: Nothing. As long as you follow the license and copyright notice - the program is free. No registration either.
