What customers say about "Key Specs"
Whistler TRX-1 Handheld Digital Trunking Scanner
  • Some people say they have problems with the AP25 1 & 2 systems.....I found that after I understood what this scanner can do and how to adjust it to perform at its best, those AP25 problems were a thing of the past.
  • I highly recommend this scanner. It works well, sounds great especially when hooked up to powered speakers and after understanding what everything does.....all the problems that people seem to have are no longer a just have to use it and figure it out.
  • Decoding and audio appear to be easily overloaded by strong signals, whether from the P25 system or nearby cellular towers. When placed side-by-side with a Uniden BCD436HP with the same identical scan list, the Uniden will receive 90% more calls. Not recommended for P25 P2 listening.
  • While unit appears to be well built, it's performance on P25 Phase II systems leave a lot to be desired. Unit will perform especially poorly on multi-site multi-cast systems.
Uniden BCD436HP HomePatrol Series Digital Handheld Scanner
  • I even pick up a NOAA station almost 100 miles away. Trunking is really good for a scanner. Very satisfied.
  • The 436 sets up easily and I was scanning within 2 minutes of putting in the batteries. The pre-programming takes all the work out of scanning. Because the 436 can receive Project 25 Phase 2, it can be used anywhere in the US or Canada
  • You can do some editing but for the most part you select where you are, how much distance from where you are that you want to hear, it imports it and you are scanning. Very easy to use, the screen is quite readable.
  • Scanning setup has gotten incredibly complex these days and I have been using scanners for 35 years. The basic complete frequency database for USA and Canada
  • Within 10 minutes after all the downloads you should be scanning the emergency departments in your area. The audio booms on this scanner.

What customers say about "Sensitivity (12db Sinad) Nominal"
Whistler TRX-1 Handheld Digital Trunking Scanner
  • The digital performance is impressive too and I've even got 4 trunking systems programmed, its easy to filter out the unwanted stuff and scan by talkgroups etc.
  • Radio was not so difficult to program as I thought. Works perfectly and great savings over other sellers although poor warranty. I recommend this scanner.
  • The scanner works fine picking up frequencies, however, after trying two, the low battery beep did not work in either scanner.
Uniden BCD436HP HomePatrol Series Digital Handheld Scanner
  • This scanner is VERY sensitive in comparison. I can hear Birmingham Alabama APCO25 system at home now almost 30 miles away where I live on the outskirts!! And that's with a 800Mhz rubber antenna!!
  • I also have GRE 500 scanner and the sensitivity of both that one and the 436 seem pretty similar. Great that the database from Radioreference is already preloaded, so fun to listen to sites I would never enter myself.
  • This handheld scanner covers just about anything you might want to listen to. Trunking operation is great. Good sensitivity. Feature rich.
  • A few draw backs that all have mentioned is that it doesn't charge the batteries while in use and the speaker could be louder. I also don't feel that the sensitivity on the unit is as good as other radios I own.
  • This scanner is very good. The only problem I have with it is that the receiver is not very sensitive.

What customers say about "Features"
Whistler TRX-1 Handheld Digital Trunking Scanner
  • If you can run a smartphone you’ll have no problems getting this scanner up and running in 5 minutes. Intuitive quick start menu lets you enter a location by Country, State/Region, County, City, Zip Code, and allows what services you want to monitor.
  • The scanner has a single large USB port for an external power source and data transfer, if you already have an appropriate 5V 2.1 amp adapter and the right USB cable, you’re good to go, I purchased a separate AC power supply and cable that powers the unit AND charges the batteries.
  • It is fairly easy to set up and run. I had a Radioshack Pro 668 and this scanner is similar to that one....same procedure to program from your computer. Can be programmed via keyboard but computer to mini SDXC card is faster and better. Can also program by just entering in your zip code.very easy.
  • The best thing to get for this or any scanner is an outdoor antenna like the Omni-X. That alone with help greatly with reception. I am now getting signals from police departments up to 70 miles away.
  • This unit does not come with an AC adapter or batteries. I got Panasonic ENELOOP NiMH rechargeable batteries to use in it, but wanted to have external power options, for obvious reasons.
  • The display is hard to read without the backlight being on, some features are unique to the American market, screen scratches too easily.
Uniden BCD436HP HomePatrol Series Digital Handheld Scanner
  • Programming is easy with the supplied sentinel software. The scanner has more features than the BCD325p2. The DMR upgrade works well with the sites I have programmed.
  • Like all smaller portable scanners the speaker is a little weak but, with earphones or light headphones the sound is really good. Back in the saddle again! Love to listen on road trips.
  • This is a very easy scanner to use that can accomplish very complex scanning tasks. Easiest use of all the scanner's features benefits from using a computer software package.
  • I was impressed at the fact that when I turned on my scanner it started scanning my area of Ohio just like the tech on the phone said it would. My husband and I have a good time, drinking tea and listening to the scanner.
  • I have owned several handheld scanners and this one is my favorite. Why? because I didn't have to program it! And program it again every time I go somewhere! Wherever I go I just punch in a zip code and I am scanning
