I use my TRX-1 daily, mostly mobile installed in my work vehicle.
It is the best hand held scanner for my needs and is like a Swiss Army Multitool due to the versatility of all the digital modes it covers.
Need to listen to P25, DMR and NXDN on my travels.
Pros:
- Good size for me, not too large or too small. Easily removed and stored/carried when vehicle is parked.
- Power can be supplied by USB or AA batteries. No messing around with weird lithium packs and external chargers.
AA's last a good while and scanner can run for days on a good USB power bank.
- BNC connector for antenna as previously mentioned. Much more robust for mobile use.
- Backlight can be selected for both keypad AND/OR display.
- Is quite robust but I still managed to crack the case front next to the display

- Once you get your head around the programming, adding frequencies and systems in software is fairly straight forward.
- Digital audio is very good (particularly P25) and not fatiguing to listen to for long periods
- Receiver is pretty good and really only melts down on an external gain antenna in town.
Cons:
- Whoever the heck it was on the design team for this model that decided the knob on top is for the squelch only on the TRX-1, is an
idiot.
Need to quickly adjust volume when mobile without looking at the radio to find the down arrow and press it repeatedly is a pain, especially with a carry case fitted that has a plastic window across the front. NO- JUST NO! The knob on the top is practically useless.
Thank goodness you can select volume on the TRX-2 rotary control!
- That rubber thing Whistler supplied is horrible, makes changing the batteries a nightmare and bulks up the radios size.
- P25 Phase 2 audio is 5 times louder than Phase 1 (may be a system issue rather than scanner?) and can be very distracting when driving.
This also occurs on the TRX-2, and I have tried audio boost on Phase 1 TG's, DAC gain settings etc, but with limited success.
- Display backlight color is fixed. Would like red for night time. I use a piece of red plexiglass from an old barcode scanner slid into the case over the display.
- I miss Close Call (patent issue) with the Whistlers and Spectrum Sweep just isn't the same!
- No 3rd party support for software unfortunately although the supplied software is adequate.
But overall I really like the TRX-1 and it is my EDC scanner (despite the top rotary knob which really is the most annoying con for me.)
Would really like to have seen an SDS100 style product from Whistler.
