UnidenSDS200 True I/Q™ TrunkTracker X Base/Mobile Digital Scanner. Incredible Digital Performance. TrunkTracker X Technology Provides The Best Digital Decode Performance in The Scanner Industry.

I have owned many scanners over the years. All have been either the Realistic brand that was sold by Radio Shack or Uniden. Yes, this radio is expensive. But this radio offers a lot of capability for that investment. This is probably the best scanning receiver I have ever owned. The receiver in this radio is pulling in signals I could not hear before without being overwhelmed by stronger signals on adjacent frequencies. The scan speed is impressive. The setup can be as easy or as difficult as you wish to make it. In my experience, the Sentinel software is needed to maximize the value of the scanner. Taking time to learn the software will greatly enhance your scanning experience. If the idea of working with Sentinel intimidates you, there are lots of videos on the tubes of you that can teach you about Sentinel.There are some things I do not like. I do not like how Uniden chose to implement WX features. I find it to be awkward and clunky. I do not like the fact that some of the functions that are required to make certain digital services work are considered optional and must be purchased separately from the Uniden website. Geez...I just paid $700 for a radio and you're telling me I gotta spend another $150 for software licenses to actually listen to digital radio?! I'm not real happy with Uniden for that one. For $700, those licenses should be included. The network port is pretty worthless unless you plan to remote control the radio. And putting on the font panel ... WTH? I would much prefer a built-in bluetooth capability. AND, if you use that LAN port, it interferes with access to the micro USB port that you will use frequently when programming or upgrading your radio with Sentinel. The micro SD card is difficult to remove and insert, and it is limited to 32GB. I'm not sure why Uniden chose to put a female USB A port on the front of the unit. It's an odd choice and an odd location for that odd choice.Fundamentally, this is a very good receiver with some very nice capabilities. Unfortunately, some of the design and marketing choices make this a very good radio as opposed to an excellent radio.

Really unbelievable how easy it is to program with the ZIP code. However you're going to want to edit it so you're not picking up tons of crap. That is a little harder but still with a little bit of reading and YouTube videos it can be done. I just added an outdoor antenna to mine which makes the reception much greater. I would highly recommend. One complaint is they don't give you a permanent way to block a station frequency without editing with a computer.Awesome price is extremely high as this unit has been out for quite a long time

Fantastic scanner. The programming and options can be overwhelming but hang in there. It's worth it. Analog and digital reception are equally good. I'm currently using mine as a dedicated P25 machine using an HD TV antenna. Don't laugh. It works great. You just have to know the tower bearing from your house. I also use a tram antenna switched in for VHF and the 10 meter band which I rarely do since I have multiple radios/scanners with their own antennas.Here's the HDTV antenna I use:https://www.amazon.com/dp/B01MYMVPVX?ref=ppx_yo2ov_dt_b_fed_asin_title

It is the best scanner I have purchased, would probably purchase another,the one problem is it isn't compatible with Apple so fixing SD card failure is a problem
