Trunking is a method of making more efficient use of radio channels by sharing them among a large number of users on a dynamic basis.

An introduction to trunked radio that I wrote for Monitoring Times magazine can be found by clicking here. Another introductory article I wrote can be found here.

The following scanners are capable of tracking at least one of the three most common trunked radio systems in use in the United States and Canada.

Yellow entries indicate scanners that are capable of tracking and demodulating APCO Project 25 transmissions. More information on P25 decoders can be found here.

The MilAir column indicates whether the scanner is capable of trunk-tracking in the Military Aeronautical Land Mobile band.

The Review column indicates the month and year that Monitoring Times magazine reviewed the radio. Many of these reviews are available on-line here. You may also order hardcopy reprints and back issues here.

The FCC ID column indicates the Federal Communications Commission Identification number. You can look up the submission information in the FCC database here.

The WinRadio 1500/3000 series radios will also track MPT-1327 trunked systems.

NOTE: At the present time there are no commercially-available scanners that can trunk-track or decode transmissions from the following systems:
  • Motorola ASTRO-VSELP and iDEN;
  • M/A-COM ProVoice, OpenSky, and EDACS Aegis;
  • TETRA and Tetrapol;
  • EF Johnson's LTR Multi-Net.

MPT 1327
  • A software-based MPT1327 trunked radio decoder is available for Linux systems using a soundcard and an ICOM receiver. You used to be able to find the software at, however it now appears to have gone missing.

  • A Windows-based program called TrunkSniff, including source code, can be found here.

  • The following are links to two hardware decoder solutions for listening to MPT 1327 transmissions:

    FTrunk (hobby decoder)
    Ptrunk (professional)

    Neither of these items are inexpensive, but I'd love to hear from someone actually using one!

VSELP (Vector Sum Excited Linear Prediction) is a proprietary Motorola digital voice product used in some early trunked radio systems (sold circa 1994).

Motorola scheduled the cancelation of portable and mobile VSELP-capable radios for early 2004, and the end of VSELP infrastructure support at the end of 2006. The following locations use (or previously used) VSELP:

  • Cleveland, Ohio
  • Hamilton, Ontario, Canada
  • Memphis, Tennessee
  • Peel Region, Ontario, Canada
  • Trenton, New Jersey
  • Warren County, Mississippi

Updates, additions and corrections to this list are certainly welcome.
