Overview & Features

Serious digital scanning. A removable control head. No paid DMR or NXDN upgrades.

The Whistler TRX-2 digital police scanner is built for people who want a dedicated radio at home, on their desk or installed in a vehicle.

It receives compatible P25 Phase I and II, DMR, NXDN and analog radio systems. Those formats come included, with no separate DMR or NXDN upgrade keys to buy.

And here's what makes this radio different: the front control panel detaches from the radio body. That gives you real flexibility when installing it in a vehicle or a tight space.

Why choose the TRX-2?

  • P25, DMR and NXDN included. Receive compatible digital radio formats without separate paid digital upgrade keys.
  • Removable control head. Mount the larger radio body out of the way while keeping the buttons and display where you can reach them.
  • Home or vehicle operation. AC and DC power equipment plus mounting hardware are included.
  • Whistler EZ Scan software. Load agencies, organize Scanlists and manage updates using Windows.
  • Spectrum Sweeper. Search for strong nearby transmissions without already knowing their frequency.
  • Record and replay audio. Save radio transmissions on the pre-installed microSD card and listen again later.
  • Custom alerts. Assign colored LED or audible alerts to departments and radio activity.
  • Scanlists and Scan Sets. Build listening groups for different situations, then turn them on or off as needed.

See the TRX-2 in action

Remember removable car stereo faceplates from the 1990s?

Same basic idea, except this time it's useful for more than making your dashboard look empty.

On the TRX-2, the control head can remain attached or be mounted separately with the included connecting cable. You can tuck the main radio body out of the way and keep the display and buttons within easy reach.

In a vehicle with limited dashboard space, that's genuinely handy. At home, leave it together and use it like a normal desktop scanner.

One clarification: That LAN-style cable links the front panel to the scanner. It's not an internet connection.

What about simulcast reception?

The TRX-2 can decode many P25 digital systems, but some complex simulcast networks cause missed or garbled conversations. A strong signal meter doesn't always mean digital audio will be clear.

The Uniden SDS200 uses specialized True I/Q technology designed for difficult simulcast reception. If that describes your local systems, it's our preferred recommendation.

If simulcast isn't an issue, the TRX-2 offers a good combination of digital format support and installation flexibility.

TRX-2 or SDS200?

Choose the TRX-2 for included DMR and NXDN capabilities, EZ Scan software, and its detachable front panel.

Choose the SDS200 when challenging simulcast is a major concern, or if you want a larger color display and Ethernet networking.
