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 Control Channel Decoding 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).

What are the Call Types available?
Column "T" = "Type" which would be [G]roup or [I]individual (iCall)
Column "Svc" = "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
For Motorola systems:
(Note that these follow the TG+n values in order.)

P - Encrypted call (followed by the call's priority 1-7) (also referred to as "Secure" or "Protected")
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.
Q: Do I need a slicer?
Q: Will the GRE, Uniden, and RadioShack radios with data port work with UniTrunker?
A: 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 data port. UniTrunker has support for EDACS, Motorola and P25 systems with the GRE PSR500/600, RadioShack Pro-106/197, and Uniden BCD396XT/BCD996XT . Also Motorola and EDACS support for the BC346XT and BCT15X Control channel output and rumored to support the RadioShack Pro-107 iScan. The support for the Uniden XT models started working at version 22.214.171.124. Support has been added to support the GRE PSR-800 IF output via the headphone jack. The IF output is turned on in the EZ-Scan Digital software or via the radio menu.
Q: How do I get the Uniden XT models to work on UniTrunker?
A: The trunked system needs to be programmed into a System. Enable the Control Channel Output in the Settings (Extended is not needed). Press HOLD on the system, the control channel should be displayed along with the SysID on the radio. Run UniTrunker. Set the receiver type to "inline", role to "signal", and set the model to your model. Set the com port to the correct one, as well as the port attributes (115200 baud rate, 8 data bits, 1 stop bit, and no parity). Set the radio run to "running". A site window should appear displaying data automatically if your settings are correct and the control channel is active.
You can verify if your radio is sending the data using a terminal program such as Windows Hyperterm or Termite to see if your radio output is set correctly.
Q: Will this work on Windows? If so, what version?
A: Yes - 2K, XP, Vista & Windows 7 (all flavors). The program won't run on Windows 95, Windows 98, or ME.
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.
