Data sheet


  • The TRX-2 allows the user to group their stored objects using up to 200 Scanlists plus a special Skywarn Scanlist. Objects can be assigned to as many scanlists as desired, giving you total flexibility to group objects and select groups in any combination for scanning.
  • Programmable audible alarms can be set to sound when certain scannable objects are active. These alarms can be used in conjunction with the alert LED described above, or separately.
  • - Record the audio received from the selected objects and searches to the Micro SD card. Play back audio recordings using the powerful built-in playback system or transfer them to a PC for playback and archiving. Record up to 50 hours of audio on the 2GB microSDr card.
  • Recorded audio files are time-stamped and the "wake-up" function allows you to program the scanner to wake up and start scanning at a specific time each day.
  • A built-in discriminator output provides the raw discriminator signal to third-party signal decoding software without risky hardware modifications.
  • Predefined service search ranges make it easy to find activity in your area.
  • A simplified keyboard and display with familiar scan, pause, skip and browse controls make using your TRX-2 easy. Behind the scenes, Whistler's proprietary object-oriented database runs the show, with support for millions of stored objects, limited only by the capacity of the MicroSD card.- With the V-Scanner II (VS-II) Extended Storage System, you can use the TRX-2 PC application to save up to 200 V-Scanner configurations to the MicroSD card, which can be recalled at any time in the field using the radio's keypad.
  • Industry standard composite USB interface with support for mass storage devices (MSD) and serial data (CDC). Access the MicroSD card without removing it from the radio, stream decoded control channel data and update your radio's firmware via USB. Mini USB cable included.
  • The TRX-2 detects and masks digital voice audio, and decodes RadioID/TalkgroupID data embedded in voice packets.
  • Uses a standard MicroSD card to store the RadioReference data library and all your programming - capacity for millions of stored objects! Supports cards up to 32 GB
  • Scans the most common signaling formats of trunked radio systems, including Motorola trunked radio networks, EDACS, LTR and P25. Both talkgroup and individual call monitoring are supported.
  • Quickly scans the TRX-2 frequency ranges for transmissions from nearby sources. When a nearby transmission is found, the TRX-2 will automatically tune to that frequency and receive the traffic. Lock the frequencies found and continue searching in the same band.
  • Customise existing programming or add new objects to be scanned and keep your TRX-2 firmware and library data up to date.
  • The backlight can be programmed to flash with custom flashing patterns when certain objects are active, providing another way to alert the operator to the presence of important radio traffic.
  • displays the weather event and triggers an alert for a specific county or counties of your choice.
  • Scan Sets extend the functionality of scan lists by allowing you to define different combinations of activated scan lists as Scan Sets and then select one or more Scan Sets for scanning using a simple menu system. With scan lists and scan sets, you have unlimited possibilities to group, activate and deactivate objects to be scanned.
  • Indicates the relative strength of the received signals. Slim, compact housing with textured exterior and large speaker - Designed for durability, one-handed operation and ease of use.
  • Provides instant access to frequencies used by storm spotters networks. Monitor storms as they occur and learn about hazardous conditions before the media or emergency management officials are able to announce them to the general public.
  • The entire U.S. and Canadian databases (www.radioreference.com) are stored on a standard MicroSD card included with the TRX-2, allowing you to access the most comprehensive radio data available without having to connect the TRX-2 to a computer or the Internet! Free downloads of database, CPU and DSP firmware updates.
  • Keep your radio's CPU and DSP firmware and RadioReference library up to date with improvements and updates as they become available with free updates!
  • The programmable tricolour LED displays thousands of colours that can be used to indicate different types of activity or activity on special channels. Program multiple colour sequences for special alerts, and even emulate the red/blue strobe of police vehicles.
