The Whistler TRX-2 is multi-system adaptive digital trunking scanners with Motorola P25 Phase I, X2-TDMA, Phase II and DMR making it capable of monitoring the following unencrypted channels/systems: Conventional DMR (Entered as a DMR trunked system, NXDN™, Hytera XPT, MotoTRBO™ Capacity Plus, MotoTRBO™ Connect Plus, and MotoTRBO™ Linked Cap Plus systems.SYSTEM REQUIREMENTS: Only for use on Windows Operating SystemsFEATURES The TRX-2 allows the user the ability to group their stored objects using up to 200 Scanlists plus a special Skywarn scanlist. Objects can be mapped to as many Scanlists as desired, giving you complete flexibility for grouping objects and selecting groups in any combination for scanning. Programmable audible alarms can be configured to sound when certain Scannable Objects are active. Can be used in conjunction with, or separately from, the Alert LED described above. Record received audio from selected objects and searches to the Micro SD card. Replay recorded audio using powerful built-in playback system or transfer to PC for playback and archiving. Record up to 50 hours of audio on the 2 GB microSDr Date and time stamp recorded audio files, and "alarm clock" 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 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 keypad and display with familiar Scan, Pause, Skip and Navigation controls make it easy for you to use your TRX-2. Behind the scenes, Whistler's exclusive Object Oriented database runs the show, with support for millions of stored objects, limited only by MicroSD card capacity. With the expanded V-Scanner II (VS-II) storage system, you can use the TRX-2 PC Application to save up to 200 V-Scanner configurations on the MicroSD Card, which can be recalled at any time in the field using the radio's keypad. Industry standard Composite Device USB interface with USB Mass Storage Device (MSD) and Serial Data (CDC) support. Access the MicroSD card without removing it from the radio, stream decoded Control Channel data and upgrade your radio's firmware over USB. Mini USB cable included. The TRX-2 detects and masks digital voice audio, and decodes RadioID/TalkgroupID data embedded in voice packets. Uses an industry standard MicroSD card to store the RadioReference data library and all of your programming - capacity for millions of stored objects! Supports cards up to 32 GB Scans most common trunked radio system signaling formats, including Motorola, EDACS, LTR and P25 trunked radio networks. Both talkgroup and individual call monitoring are supported. Quickly sweeps the TRX-2's frequency ranges for transmissions from nearby sources. When a nearby transmission is found, the TRX-2 automatically tunes to that frequency and receives the traffic. Lock out found frequencies and continue searching the same band. Customize existing programming or add new objects to scan, and keep your TRX-2 firmware and Library data up to date. The backlight can be programmed to flash with custom flash patterns when certain objects are active, providing another way alerting the operator when important radio traffic is present. displays the weather event and sounds an alert for a specific county or counties of your choice.
