 The installed Micro SD card that contains the entire USA/Canadian Radio Reference database
The Whistler TRX-2, desktop/mobile version of the TRX-1 device, is a multi-system adaptive analog and digital trunking scanners capable of monitoring unencrypted channels/systems in P25 (Phase I, II, Motorola, X2-TDMA) and DMR (Tier II, Hytera XPT, MotoTRBO Capacity Plus, MotoTRBO Connect Plus, MotoTRBO Linked Cap Plus) as well as AM, FM, LTR, EDACS (wide/narrow by GE/Ericsson/HARRIS), NXDN. The TRX2 scanner use Object Oriented User Interface (OOUI) designed to help the hobbyist to build a collection of channels to scan. The Object Oriented scanning simplifies the process by using common conventions for concepts that have common characteristics: a scannable object is any defined item that can be monitored including conventional non-trunked radio frequencies, talkgroups used on a trunked radio system, radio services, defined searches. Because objects are defined by the same basic elements the User Interface is designed to simplify scanning by managing all items similarly. When you learn how to program one type of object, you can program other types of scannable objects as well.

- Audio Recording
Powerful system that captures transmissions that occur on selected Objects to the Micro-SD card using the high quality .AU audio file format. Record all transmissions that occur on talkgroups or channels, perform attended or unattended searches for new frequencies - automatically storing audio with frequency information for all transmissions found while searching, also record all transmissions that occur on all talkgroups or channels providing an instant recall function to replay a prior transmission that was missed or unintelligible.
- Built-in clock/calendar.
- Built-in services searches.
- Built-in discriminator output
Provide its IF/discriminator output signal to the headphone jack. The output is unsquelched and unfiltered, making it ideal for third party signal analysis and decoding software and hardware.
