Setting Up Your SDS100
Initial setup involves powering on the radio and potentially connecting an optional GPS receiver for location-based channel selection and optimal performance.
Initial Power-Up and Basic Operations
Upon initial power-up, the Uniden SDS100 begins a system check and loads the current database. Users can manually input their location or connect an optional GPS receiver to automatically select relevant channels for their area.
The radio allows adjustment of the scan range, from 0 to 80 kilometers (0-50 miles), refining the channel selection process. The database, updated weekly by RadioReference, ensures access to the most comprehensive and current radio system information.
Basic operations include navigating the menu system using the controls, adjusting volume, and initiating a scan. Familiarizing yourself with these fundamental functions is crucial before exploring advanced features.
Connecting a GPS Receiver
An optional GPS receiver significantly enhances the Uniden SDS100’s functionality by automatically determining your location. This eliminates the need for manual location entry, ensuring the scanner selects channels applicable to your precise geographical area.
Connecting the GPS receiver typically involves a serial connection to the SDS100. Once connected, the radio will acquire GPS signals and update its location data. This process may take a few minutes initially, depending on signal strength.
Ensure the GPS receiver is properly powered and positioned for optimal satellite reception. Accurate GPS data is vital for the SDS100 to deliver relevant and localized scanning results.
Location Settings and Channel Selection
The Uniden SDS100 allows you to define a search area, adjustable from 0 to 80 kilometers (0-50 miles), to refine channel selection based on your location. Whether you manually input your coordinates or utilize a connected GPS receiver, the radio intelligently filters channels relevant to your specified vicinity.
The SDS100 leverages a regularly updated database, maintained weekly by RadioReference, a comprehensive repository of radio systems. This ensures access to the most current channel information for optimal scanning performance.
Proper location settings are crucial for receiving local broadcasts and emergency communications effectively.

Programming the SDS100
Programming can be achieved through manual channel entry, utilizing RadioReference database updates, or employing dedicated CPS (Computer Programming Software) for advanced customization.
Manual Channel Entry
Direct channel input allows users to precisely define frequencies and settings without relying on external databases or software. This method requires accurate frequency information for the desired channels.
Carefully consult reliable sources, like the RadioReference database, to ensure correct values are entered. The SDS100’s manual emphasizes using accurate data for optimal performance.
Manual entry is particularly useful for unique or localized frequencies not readily available in pre-programmed databases. Remember to double-check all entered parameters against official documentation or verified sources to avoid errors and ensure proper reception. This provides granular control over your scanning experience.
Using RadioReference Database Updates

RadioReference provides weekly database updates, offering the most comprehensive repository of radio system information available for the Uniden SDS100. These updates ensure your scanner receives current frequencies and channel details for your specific location.
The SDS100 can utilize these updates to automatically populate its channel lists, simplifying the programming process. Connecting an optional GPS receiver allows the radio to select channels relevant to your current locality.
Users can also adjust the range selection from 0 to 80km (0-50 miles) for broader coverage. Regularly updating the database is crucial for maintaining accurate and effective scanning capabilities.
Programming with CPS Software
CPS (Computer Programming Software) offers an advanced method for programming the Uniden SDS100, providing greater control and customization compared to manual entry or RadioReference updates. This software allows users to create, edit, and upload channel configurations directly from a computer.
While more complex than other methods, CPS enables detailed settings adjustments and bulk programming capabilities. It’s particularly useful for experienced users or those needing to replicate specific system configurations.
