Setup, Guides & Resources

Programming your Whistler TRX-2

The TRX-2 comes with a big radio database and plenty of digital features. What makes it useful is organizing those systems into Scanlists that actually match what you want to monitor.

Option 1: Let Zip Scanners handle it

Our recommendation for most buyers. Tell us your city, county and state, and which police, fire, EMS or other agencies matter to you.

Our technicians research the available systems and build sensible Scanlists around compatible channels. We'll also flag areas where the SDS200 makes more sense because of difficult simulcast reception.

Instead of spending Saturday learning programming software, you can spend it listening. Add Expert Programming or use the purchase options above.

Already own a TRX-2? We can help with programming on compatible radios purchased elsewhere, too.

Programming cannot decode encrypted channels or guarantee reception when suitable signals aren't available.

Option 2: Do it yourself

Whistler EZ Scan is free Windows software that lets you manage radio databases, Scanlists, Scan Sets and scanner settings. You'll need reliable local radio data and some patience to configure everything correctly.

Download Whistler EZ Scan for free. Our four-part tutorial below will help you get started.

Mark's site looks like it belongs next to an old dial-up modem. But the information is excellent. His guides dig into Scanlists, settings, programming and remote-head details that typical product listings skip.
