The Whistler TRX-1 is a digital handheld scanner, direct sibling to the TRX-2 Desktop/Mobile Scanner, capable of numerous Digital Modes used in today's Public Safety arena and many amateur & business use digital transceivers. It was announced in May 2016 and released in late June of the same year. The TRX-1 comes complete with the Radio Reference data base on a micro SD card. Upon receiving the unit, be sure to update it to the latest firmware before scanning. The scanner interfaces only with a proprietary software called EZ SCAN™ for programming. Some users report connection problems with Windows based PCs.
The Whistler TRX-1 is a handheld multi-system adaptive digital trunking scanner it allows for 4 AA batteries to take handheld on the go, allowing 7-13hrs hours of continuous monitoring. The scanner is capable of decoding numerous modes of analog and digital transmissions, to include but not limited to: Motorola P25 Phase I, Phase II, DMR, and NXDN making it capable of monitoring the following multiple channels and/or systems at any given time (does not and will not decode Encrypted channels or Systems).

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.
- SCAN SETS - expand the functionality of Scanlists by allowing you to deﬁne different combinations of enabled Scanlists as Scan Sets, then you can select one or more Scan Sets for scanning using a simple menu system. With Scanlists and Scan Sets you have unlimited possibilities for grouping, enabling and disabling objects for scanning.
- EXPANDED V-SCANNER II(2) STORAGE SYSTEM - with the expanded (VS-II) storage system, you can use the PC Application to save up to 200 V-Scanner conﬁgurations on the Micro SD Card, which can be recalled at any time in the ﬁeld using the radio’s keypad.
- AUDIO RECORDING - 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 over 50 hours of audio.
- BUILT-IN CLOCK/CALENDAR - date & 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.
- BUILT-IN SERVICE SEARCHES - provide predeﬁned service search ranges make it easy to ﬁnd activity in your area.
- WHISTLER’S EXCLUSIVE ALERT LED - programmable tri-color LED displays thousands of colors that can be used to indicate different types of activity or activity on special channels. Program color sequences with multiple colors for special alerts, even emulate the red/blue strobe of police vehicles.
- PROGRAMMABLE AUDIBLE ALARMS - can be conﬁgured to sound when certain objects are active.
- PROGRAMMABLE BACK-LIGHT AND ALERT LED FLASH PATTERNS - The back-light 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.
