Whistler TRX-1 Review

And the Whistler TRX-1 is designed for that purpose. In this review, we’d like to highlight its features, drawbacks, and give you a consumer opinion so you can get a full perspective on how it works. Without further adieu, let’s start the review!


  • Zip Code Programming
  • Backlit LCD display
  • USB Interface 2.0
  • Functional Keypad
  • Object Oriented Scanning


The Whistler TRX-1 is a digital trunking system that’s compatible with X2-TDMA, Motorola P25 Phase I, which makes it capable of monitoring unencrypted systems: MotoTRBO Connect Plus, MotoTRBO Capacity Plus, and Hyerta XPT. For those wanting better police communications, look no further. 

Frequency Coverage

The Whistler TRX-1 covers frequencies of police scanners ranging from 25 to 1300 MHz. It skips cellular bands and broadcasts television and radio, which is standard for most two-way radios. With this frequency coverage, users can find the right frequencies and hear police conversations and reports in their area. 

Micro SD Card Compatible

One thing we like about the Whistler TRX-1 is its Micro SD Card. This augments the device’s capabilities in a few ways. For instance, you can use the card to store millions of objects. Since it has 32GB of memory, that’s plenty of space to save recordings.

Additional Features

Alongside its compatibility, the Whistler TRX-1 gives additional features like an alarm clock function, a set of intuitive controls and an extensive scan list. These features combined make the Whistler TRX-1 more efficient than its top competitors (see best ones here: https://ratedradardetector.org/police-scanner/best/). 

Note, this scanner is not a good choice for first time users; you’ll find this device overwhelming. If you are confused with it as first, make sure you read the manual to see how to operate it correctly. 

Object-Oriented Scanning

While programming scanning receivers is difficult, object oriented scanning helps make the scanning process easier.  The programming is based on your location, so make sure you have the right logistics to ensure that it works properly. 


Good Channel Compatibility

One thing we like about the Whistler TRX-1 is its channel compatibility. You’ll be able to monitor some different unencrypted channels. Because of this, its a great device if you like to have multiple channels logged at once. See our choices of best police scanner antennas listed and reviewed here.

Durable Rubber Covering 

The Whistler TRX-1 has a strong rubber case which can be attached to your belt. While it won’t protect the front side from scratches, it does help reduce device shock from drops. So think about getting this device if you want something that will stay in place while in operation. 

Transmission Review

Another feature we like about the TRX-1 is its ability to review recorded radio transmissions instead of listening to them. Users can scroll through the different recordings and only tune into their desired channels. This is a less time-consuming method than its previous models, making it great for users who want reliable transmission communication.

Audio Quality

Users had a positive reception when discussing the TRX-1’s audio quality. When in use, the user can hear the channels clearly, without too much static or white noise on their end. Get this radio if you want to experience clear communication at an affordable price. 

Encrypted Transmissions

You’re allowed to either receive or skip encrypted transmissions using this device. While you’ll be unable to understand the transmissions, knowing that the transmissions are being created is informative. 

One setting for the encrypted transmission is a telephone sounding tone the device makes once the private channel is operated. Thus, making it a great choice if you want to utilize both encrypted and unencrypted channels with your scanner. Interested to know another police scanner with encrypted transmissions?

Difficult Interface

The TRX-1 has a difficult interface which might be challenging for beginners. The biggest issue we have with the interface is the difficulty of adding in new channels. While other devices allow you to toggle through frequencies with the press of a button, the TRX-1 has users select an object from a menu and have it selected so they can hear it. This is an inconvenience to some, as the complex interface can take time getting used to. 

Programming Features

If you prefer to program your channels manually, you should look elsewhere. Some users have complained about how challenging the programming is. This could be a matter of consumer subjective opinion, as other users begged to differ. 

Limited Display System

The display system is not up to par in comparison to competing brands. The screen is small, and the contrast is too low, which makes it difficult to read. The symbols placed on the device are hard to decipher and interpret. 

Short Battery Life

The Whistler TRX-1 has a short battery life. On average, it runs for 4-5 hours on a full charge. This isn’t good if you’re in need of a high-quality daytime scanner. You’re going to replace your batteries often which can be difficult because of it’s hard to remove the battery compartment. 

Consumer Opinion

Consumers had a fairly positive opinion on the Whistler TRX-1, as well as other models from the brand such as the WS1040. Here’s what they had to say:

While the programming can be confusing at first, there are resources online that can help you get started. For instance, one consumer stated that YouTube videos have helped them understand the mechanics behind the radio and started to program channels faster than manual methods. 

Compared to other devices (best ones here), this unit is of high quality. It has a good case for protection, easy to read buttons, and good audio sound. In fact, you can charge the device while still listening, which is convenient when you want to tune into your favorite channels. 

Whistler TRX-1 Review Conclusion

Basically, you should get the Whistler TRX-1 if you want a high-quality police scanner. Not only is it reliable, but it has features (channel connectivity, audio quality, etc.) which enhance its operational duties. So consider getting this if you want to hear police communications and improve your communication experience.
