WR Trunking Software

Conventional two-way radio is quickly disappearing. It is being pushed aside by trunked radio, which offers a much better spectrum utilization. Trunked radio relies on computer-allocated radio frequency channels, and is therefore eminently suitable for reception by computer-based receivers such as the WiNRADiO range.

Fully integrated with WiNRADiO receiver software, and is suited for monitoring of Motorola SmartNet® and MPT1327 trunking networks, the two most commonly used trunking systems world-wide.

Possible to follow conversations on the trunked networks, relying on the control channel data transmitted by the base station, provide information about systems characteristics, log traffic activity, and automatically build up databases of trunking networks.

The software takes advantage of the ubiquitous and economical PC sound card to implement the latest digital signal processing algorithms for data decoding and analysis.

low-cost, and is intended mainly to satisfy the needs of a serious radio monitoring enthusiast as well as for budget-conscious professional surveillance applications.

More detailed information and technical specifications

The components of the WiNRADiO Trunked Option are provided in the form of XRS plug-ins, selectable by clicking on an item in a menu. The SmartNet and MPT1327 modules are similar in appearance and functionality. The XRS plug-ins ensure upward compatibility with all future versions of XRS-capable receivers. (For more information about the XRS technology refer to the XRS Web site.)

WiNRADiO receiver

In 'single-receiver mode', the decoder stays on the control channel of a trunking network, waiting until all the necessary conditions allowing it to tune to the voice channel are met. While monitoring a voice channel, the control channel cannot be decoded. The receiver returns to the control channel automatically after the transmission on the voice channel terminates.

In 'dual-receiver mode', one of the receivers stays permanently on the data channel while the other follows the desired voice channel. While the second receiver is not tuned to a traffic channel, its output is muted. This mode ensures continuous data channel receiving and decoding, making it possible to achieve an easier and faster following of the desired stations (sometimes a station is sent from one channel to another and in this mode the decoder can react immediately).
