Fleetsync II Decoder
Fleetsync is a digital radio identifier, status, GPS, and data protocol that is normally used in addition to other trunked radio protocols and/or on conventional radio channels. The decoder decodes Automatic Number Identification (ANI), Acknowledgements, Status and GPS messages. If you discover additional message types, please share them with the author for inclusion in the decoder.
Using Fleetsync Decoder
Select the Fleetsync decoder in the Aux tab of the channel configuration window. If you are decoding a conventional channel, then use the NBFM decoder as the primary decoder. The Fleetsync auxiliary decoder can be used in addition to any of the primary analog trunked radio decoders.
GPS
GPS data bursts normally occur on a conventional radio channel, separate from normal voice communications. Each mobile radio has a unique timestamp that tells it when to broadcast, so that users don't broadcast on top of each other. In addition to the defined time to transmit, radios are told how often to broadcast. Broadcast updates of 1, 3, 5 and 6 minute intervals have been observed.
Smaller fleets may broadcast more often. Larger fleets will broadcast less often, because each radio must have an opportunity to broadcast at least once within the repeat interval.
Status
Mobile radios are programmed with a pre-defined list of canned status messages. The decoder will display the status number received. If you can determine the meaning of each status number, you can alias the status number with a status alias identifier so that the meaning is displayed, instead of the status number.
Acknowledge
Some radio networks will acknowledge status messages. When this happens, the mobile radio will broadcast a status message, and the network will immediately respond with an acknowledgement.
