Frequently asked questions
The True I/Q feature in the Uniden SDS100 scanner refers to its advanced signal processing capabilities. It's designed to provide improved digital performance in areas with weak signals or where signals are distributed across multiple antennas, commonly known as simulcast areas. This technology helps minimize dead zones and maximizes your chances of picking up and decoding signals that other scanners might miss.
The Uniden SDS100 scanner is designed with JIS 4 weather resistant construction. This makes it capable of withstanding light rain or splashing water from any direction. However, it's not fully waterproof and should not be entirely submerged in water or exposed to very heavy rain for prolonged periods.
The Uniden SDS100 scanner has True I/Q receiver technology. This technology greatly enhances the radio's ability to receive weak or distant signals, even in areas where signals are distributed across multiple antennas, known as simulcast areas. This feature is especially useful for emergency personnel or radio enthusiasts who need reliable performance in varied signal conditions.
The Uniden SDS100 scanner is built with rugged, JIS 4 weather resistant construction. This means it can stand up to rough handling and light outdoor weather conditions like rain splashes. However, it's important to note that while it's designed to be rugged and durable, it's not indestructible and should still be handled with care to prolong its lifespan.

Should I Buy It?
If you're an individual who spends a fair bit of time on the radio and requires a reliable scanner with exceptional performance, the Uniden SDS100 is definitely worth considering. Despite the minor drawbacks mentioned, the general consensus is that it's the best, most versatile scanner available today.
This is an AWESOME scanner and a worthy upgrade. Is it perfect? Nope. Uniden should have included some features that would have added significant value to the user. A few of those things are 1) Bluetooth 2) Ability to lockout keypad (seriously?) and 3) Ability to use AA batteries as a backup if needed. Are those all of them? Nope. But they are a few of them that irk me at the moment. The scanner overall is wonderful and amazing. The speaker is loud and clear, the reception is really great, and I pick up neighboring counties that I have never been able to pick up previously, and that’s just using the stock antenna that came with it. The programming of this scanner is extremely easy. I had considered purchasing from another retailer as they had me scared to death about the complexities of setting up the programming. It’s no sweat. Everything is pretty much already set up in the scanner. Just set up your favorites list, then enter your zip code location (in that order as one reviewer pointed out) and your set! There are a lot of customizable settings, pretty much everything by system, and it’s fun to play around with all the different settings and screen colors. The reason I ended up purchasing on Amazon was for the extended warranty. I have enough experience to know, that you never know with Uniden what you will get long-term, and it was an inexpensive peace of mind to add that warranty through Amazon. I trust that if they ever need to make good on it, they will. I did not really need to utilize the Sentinnel software... well because everything is pretty much already databased in the scanner, and it’s easy to get it set up the way you want it. My concern with Sentinnel is that we have all Mac’s, which it won’t run on. I downloaded the parallel stuff and spent hours getting it all set up, but just couldn’t get it to work. I ended up finding a super easy solution that worked easily and perfectly on my Mac, which I’ll paste below if it would be helpful to someone else. It’s important to note once again, that I really didn’t need to do anything with the Sentinnel software, but I guess it’s nice to know I have a backup of all my settings now. The instructions below may look intimidating at first, but trust me it’s really quite easy and pain-free. Here it is: 1. Go to WineBottler |*Run Windows-based Programs on a Mac and download WineBottler. I used the 1.6.1 Stable on Mavericks. It will pop up an ADFly Page. Just give it 5 seconds then click the “SKIP AD” button in the top right. (If you get any more ad pop ups just give it a few seconds and it will start downloading.) Once finished: Move “Wine.app” and “Winebotter.app” to you applications folder. 2. Download the latest Sentinel Version. BCD536HP < UnidenMan4 < TWiki and unzip it to your desktop. (or where you fell comfortable) 3. Launch “Winebottler” from you applications folder. Follow prompts for install. This will install any needed files to run the apps later. a. Click “Advanced” in the top bar. b. Select “new prefix” default c. Program to install: “select File…” and select the “Setup_BCDx36HP.msi” in the Sentinel folder on your desktop. d. check “This is an installer, execute it. e. in the “Winetricks” section, click in the search field and search for “dotnet20”. Check the MS .NET 2.0. (this will install the .net for the Sentinel to install) f. Click “Install” button. Save to your desk top as Sentinel. This is now creating a windows app that will run on your mac using “wine”. It will install the Dot Net files and you will have to agree to terms and tell it where to install. Defaults will be fine. That will finish and then Sentinel will star the install. Again, agree and save to defaults. This part does take some time so bear with it. (HINT: sometimes the installers will pop up in the background. You may have to click the doc to bring it forward to agree to the DOT NET terms etc…) Once the files are installed, the last step is to “Select Startfile” leave it on Program Files/Uniden/BCDX…… and when you click the “Sentinel” app it will launch the app. Hit OK and your done. Now double click the newly created app and your ready to run Sentinel on your mac.

I'm a Ham radio operator and over the years I have had dozens of scanners. I also own the SDS200 (base/mobile version of this radio) Most scanners don't die but the changing radion standards make them obsolete. This is the premium scanner that will handle the most radio systems that operate today. Analog, digital, trunked, it does them all. However you have to pay extra for and unlock key for NXDN ($50), DMR ($50) and ProVoice ($50) and if you do want these go directly to the Uniden site otherwise everyone else will charge $75. If you are just doing public service monitoring you won't need these options but I do a bit of commercial and business monitoring as well and many of them are NXDN or DMR. I don't think anyone except San Antonio Police use Provoice anymore. Actual performance is great across all bands and intermod is well filtered. There are some idiosycrancies to it but go to radioreference.com forums to figure that out as I could go on for days. But overall it is the best most versatile and feature rich handheld scanner you can buy today. I live in an area with some radio systems that are problematic for many scanners (simulcast issues) and this one handles them all like a champ. A couple things to know. There is no keyboard lock function which I REALLY dislike but I figured out a hack how to lock the keyboard via the free programming software but it's a total hassle and not practical. So it can be done and perhaps that will be a part of a future firmware upgrade. Also the unit gets pretty warm when operating, that's normal. The battery is pretty big and sticks out from the back of the unit which is a little dopey looking but overall not an issue with usability. It's just wen they first released them the original battery was way to weak so they now ship with the extended battery (about 8 hours) and it works fine. Actually the previous model would fall over all the time when you set it on a table and this bigger battery prevents that, so that's a plus. I bought a second battery and I've actually never used in about six months. It's a shame they didn't put bluetooth in it, but they did make it so you can charge the batteries while listening which you couldn't do on the previous model so that's a big plus. The build is very sturdy and I'm sure I will replace this radio when technology changes not because the radio itself stopped working perfectly (like my last six scanners). It's is waterproof and much sturdier than the previous model. Sound quality is great and loud enough in very noisy environments.

For those that mention keypad lock... It is the function key and the power button... That turns it on and off... Same as the BCD436HP handheld scanner... I hope this helps some folks,, I have seen it mentioned as not being there.. The little pad lock decal is not there, but the actual function is... Great scanner, awesome features and performance, and some should read the manual... The key lock function is in the manual..
