The TRX-1 includes a case with two snap-in inserts in gray and green.

Believe it or not, Whistler is doing more than Apple in terms of protection and color options.

Right up until the Uniden SDS100 launched in June, this was our top selling scanner of 2016, 2017, and 2018.

Customer feedback on the TRX-1 has been overwhelmingly positive.

All of our internal staff sampled this scanner when it launched in 2016...
so that's why our stock count has been off by 5 for nearly three years now(?)

Battery & Powering Scanner

The TRX-1 is not powerful enough to charge batteries.

The solution is an external 4 bay AA battery charger, which you can add on this page.

We STRONGLY recommend all buyers add this. Some buy 2 sets of batteries so they always having a fresh set.

How is the Whistler TRX-1 different than the the other phase 2 handheld scanners?

› The TRX 1 & 2 are the only scanners on the market capable of monitoring the NXDN. NXDN is a version of digital phase 2.
› The TRX-1 is the only scanner that comes with a case ($34.99 value) standard. The color inserts are also one of a kind.
› The TRX-1 has several minor technical upgrades that, while not game changing, cumulatively they make the scanning experience more enjoyable and easier.


I need a phase 2 digital scanner, why should I buy the TRX-1?

The TRX-1 was the best scanner on the market (2016- June 2018) and comes with upgrades over older scanners. NXDN is also a long sought after format to monitor and the TRX is the only scanner capable of monitoring this out of the box. The case and colored inserts are nice free add ons to protect your scanner. The overall user experience is great and Whistler continues to roll out new, free updates to their new flagship scanner. As this is our top seller (and the one all our employees own) we make more guides, tutorials and how-to's on this scanner over any other.


When will the TRX-1 go on sale?

We don't know. Whistler does not disclose when they will be dropping prices and even when prices do drop, it is usually only $5 -$10. You can sign up for our emails & we'll keep you posted. Also, we have a best price guarantee.


What’s the difference between the TRX-1 and the BCD436HP?
Go to 'Specifics & Compare' tab to see technical differences or watch this comparison video. The main differences are:

› TRX can charge while powered on; BCD436HP must be powered off to charge.
› Whistler regularly upgrades their scanners for free; Uniden charges $50+ for upgrades.
› Whistler has knowledgeable staff you can call; Uniden does not offer phone support and limited email support.
› BCD436HP came out in 2013; TRX in June 2016. Like all new technology there have been several upgrades.
› TRX has a free case, BCD436HP does not.
› The BCD436HP has been recalled a few times since it launched.


Additional Memory?

You can add a larger memory (SD card) to increase favorites lists and recording space. Recording time by SD card size:

› 4 GB = 12 hours
› 8 GB = 24 hours
› 16 GB = 50 hours
› 32 GB = 100 hours
› 64 GB = 200 hours


How do I remove the case?
It's REALLY on there but it comes off. Remove the color insert before removing the case. this video shows you how to remove .


Can I charge the batteries from the scanner when it is on?

Yes, HOWEVER, this takes a very long time and the batteries will not fully charge. We recommend an external battery charger and 2 sets of rechargeable AA batteries; all of which can be added on this page. This way you can always have a fresh set up batteries. The batteries we sell last about 8 hours on single charge; Energizer/Duracell last about 5 hours.


External battery charger?

The TRX-1 is not powerful enough to charge the batteries we sell (or any battery) to full power. The solution is an external 4 bay AA battery charger which you can add on this page. We strongly recommend all buyers add this and the only reason we do not make mandatory is some already have.


My screen is scratched.

The faceplate is not done with a fine finish and may appear to be scratched but this is how Whistler scanners look. We cannot replace your unit due to the finish on the screen - this is how they ALL look. We are aware that the TRX-1 looks like they are damaged but this is just how they are done. We have brought this up with Whistler for years as it leads to upset users but this is just how Whistler manufacurers them. This is one of the many reasons we recommend Uniden SDS100 the over the TRX-1.


My Battery Life Display is Not Accurate.

The battery display on the TRX-1 does not function properly. Sometimes this works and sometimes it does not - the issue comes and goes with software updates from Whistler. This is an issue with the TRX-1 and we have this here to make buyers aware of this issue before they purchase and to state that we will not replace your unit due to this issue. If you are experiencing this issue we recommend making software update, if this does not fix issue, wait till next software update (usually monthly) and make update again.

Buyers Say

› Does not have WiFi or Bluetooth capabilities.
› Does not come with batteries (add above).
› AC adapter is not included (add above).
› Not GPS capable.
› Make sure AA batteries are fully recharged prior to putting into scanner.
› TRX cannot fully charge batteries. We recommend 2 sets of batteries and external battery charger.
› The faceplate is not done with a fine finish and may appear to be scratched but this is how all Whistler scanners look.

Police Scanner Programming FAQ

What is 'One Touch Start Up'?

Adding this with programming allows our technicians to make hardware, software & frequency updates prior to shipping your scanner. You can buy only the programming which will give you everything needed to listen in your area but 'one touch start up' ensures a smooth experience right from the start with zero technical know-how. 'One touch start up' is popular with gifts as this allows the scanner to simply 'work' by powering on.


How long does this take?

Programming adds 1-2 additional business days to delivery.


What if this does not work?

We have a 100% money back guarantee if you’re not happy with your programming.


How are you so much cheaper than other scanner programming places?

We’re awesome.


Can you program X, Y, Z?

We can program anything that is in Radio Reference. If you have frequencies that are not in Radio Reference, as long as you can put them in a CSV file, we can program them.


What if I need help?

We’re always here to help.


Can I programming this scanner myself?

We created a programming decision tree as well as programming videos (above) to help you decided on whether you should include professional programming with your scanner but we HIGHLY recommend adding programming.


Can't I just punch in my zip code for programming?

When you type in your zip code, it scans EVERYTHING in your area, which is kinda like getting the phone book thrown at you. This is why over 95% of orders include programming & why we highly recommend. Our professional programming filters the junk out so you don't have to listen to things such as the dog catcher, repo guy, power company & such.


How long does programming take?

It takes our scanner tech over an hour to program each scanner & this is ALL he does. For new & moderate scanner users we estimate 3-12 hours of programming. Setup time varies wildly based on scanner, area as well as scanner & general tech familiarity.


Why should I buy programming?

Programming is the #1 reason police scanners are returned. While scanner programming is much easier than the days of crystal scanners, there is a learning curve like any other electronics purchase. While some scanner enthusiasts are highly technical and want to learn the ins and outs of programming, others want their scanner to just ‘work’ right out of the box. 95% of all scanner sales include programming, so unless you’re familiar with scanners, scanner terminology, own a PC (Mac’s do not work), and want to learn the nuances of programming, we highly recommend having your scanner professionally programmed. Scanner technology is fairly user friendly, but scanners are not smartphones or iPads. If you're spending hundreds on a scanner; we recommend springing a few extra bucks so it works right out of the box.


Can't you teach me programming with your lifetime technical support?

No. Lifetime technical support is not unlimited technical support. We are always here to help, love to do so. We made how to videos and can help point you in the right direction, but we will not teach programming.

Very happy with my whistler trx-1 (Posted on 8/12/2016)
Would recommendReview by John Krause
Review Rating
I purchased a Whistler TRX-1 and, although there is a learning curve (I am a first time scanner buyer), I had it up and running in no time--first using the set location feature (yep, it works!), and soon after also with the Whistler software for WIndows. The Windows was a little more challenging as I had to get a scanner driver to install (thanks to forums), but I now have this all running smoothly as well. Within 24 hours of unboxing my scanner, it has the current CPU firmware and libraries installed and I am scanning everything that I want.

So, yeah, happy to give this whole experience five stars! Thanks Zip Scanners! (Posted on 8/12/2016)

Bought this because of the new systems it could receive. Also bought a bcd436hp. Side by side, the Whistler reception is sub par except for low band. Great reception on low. However my departments are on 800 trunked, and if I have both locked on the dispatch tgid the bcd436 will work but the Whistler won't unless I hold it above my head. (Posted on 8/10/2016)
