Another is how the SDS200 is programmed. With your 150 your bumping in the Frequencies by hand . It can be done with the 996 and 15x but The police in my city are now on digital and so this Uniden Software Defined Scanner seemed to be the appropriate radio for my needs. There are two basic ways to run this scanner: off a "hand entered" FAVORITES LIST or a LOCATION based list (eg zip code lookup using the built in database at each startup). It is possible to boot up to a location based scan + your favorites list by default when you turn on the scanner. This might be useful during a natural disaster. If you assign a Startup Key to your Favorites List you can boot only to your Favorites List by holding down the appropriate key at startup. This is more useful for limiting your scan to Police and local UHF/VHF traffic. MicroSD card (provided - 1 GB up to 32 GB supported) – For storing Favorites Lists, Profiles, all your settings, Discovery sessions, and recording sessions. All in all, it's a great scanner and I look forward to many years of fun with it. I hope to buy an SDS 100 soon so I can have a portable scanner as good as the SDS 200.

True I/Q™ Receiver – Designed to improve digital performance in even the most challenging RF environments. An I/Q receiver captures the complete signal waveform in 3 dimensions, allowing for improved digital error correction and signal recovery. Although here in Scotland we don't have the complicated systems such as provoice and simulcast like our fellow enthusiasts in America / Canada the radio will decode moderate to strong signals easily . The same cannot be said for weaker signals .HomePatrol Database – Includes all known radio systems in the US and Canada. The database is updatable with the Sentinel software and Uniden updates the main database weekly. Repeater Find – Allows the scanner to try to switch to the repeater frequency if an input frequency is found. Search Avoids – You can temporarily Avoid up to 250 frequencies and permanently Avoid up to 250 frequencies in any Search mode or Close Call mode.

When the Software Defined Scanners came along with uniden punching through the market with their flagship SDS100/200 I thought it was worth a shot .The SDS200 is Sentinal based using a data base here a RR. Yes you have the option of Favorites and adding seperate frequencies but Search Keys – You can assign 3 of the number keys to start a Custom Search, Tone-Out Search, or Close Call Search.

Custom Alerts – You can program your scanner to alert when you receive a Channel or Unit ID, a Close Call hit, an ID is transmitted with an Emergency Alert, or a Tone-out hit. For each alert, you can select from 9 different tone patterns, 15 volume settings, 7 colors, and 3 flash patterns. All settings for the SDS-200 are stored on a micro-SD card, which is included. You can either use a USB cable (supplied) to connect your PC, running the Sentinel software to the scanner, or you can take the micro- SD card out of the scanner and insert it into a reader on your PC and edit the configuration If your not used to menu driven radios this can be daunting but my advice is to persevere , you will get used to these menus over time .Another thing is the database which is dedicated to the US/Canada, We dont have access to such a database outside of those coutries. Therefore we have to manually build our own favourite/scan lists which can be time consuming . In addition to the frequency selection the more expensive scanners often allow you to switch the mode between AM & FM. On the cheaper ones this is often done automatically and you can not change it. Multicolor LED Alert – The alert LED with 7 colors, Blue, Red, Magenta, Green, Cyan, Yellow, or White, can be used with your Custom Alerts. Some of the bands covered by scanners are: Aircraft, Marine, Amateur Radio, Taxis, 2-way radios, Motor Sport, etc.

Second Hand Uniden SDS200 VHF UHF Digital Base Scanner, FEATURES, FUNCTIONS AND SPECIFICATIONS: MAIN FEATURES PC Programming – Use the Sentinel software to manage your scanner’s Profiles, Favorites Lists, Databases, and firmware updates.The State Police for Your Area In Analog Trunk for the most part and Your Local Police are using the P25 Platform or Analog UHF. Range Control – Lets you set how far out from your current location the scanner will search for channels in Favorites Lists and the database. Customizable Color Display – You can set the display color for each field in the display. Additionally, for many fields you can select the information provided. Another way to ensure top speeds is to make sure your frequencies are laid out ascending from lowest to highest in each system. That will help a lot . As the unit is Software Defined Radio based with internal RTL chip hardware it is dependant heavily on filters (another story but you'll understand when you come across them) .
