MPT (Ministry of Posts and Telegraph) 1327 is a trunked radio standard for analog radio that originated in Britain in the late 1980s.
It is popular in Europe, Australia, and numerous countries outside the United States.
There are a growing number of MPT-1327 systems in the U.S.
The standard itself can be downloaded
The MPT-1327 specifications are actually four documents:
- MPT-1327 defines the message and modulation format
- MPT-1343 defines a terminal access interface
- MPT-1347 defines a base station interface
- MPT-1352 describes terminal testing
- A software package called TrunkView
can be found
It requires a receiver and a computer with a soundcard.
If the receiver has a serial port, the computer can control the
operation (primarily tuning) of the receiver.
- A Windows-based program called TrunkSniff, including
source code, can be found
- 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
www.unixforge.org/~tronkito, however it now
appears to have gone missing.
- The following are links to two hardware decoder solutions for
listening to MPT 1327 transmissions:
FTrunk (hobby decoder)
Neither of these items are inexpensive, but I'd love to hear from
someone actually using one!
