Overview
A handheld digital trunking scanner built on Uniden's True I/Q receiver technology, aimed at listeners who need reliable decode in weak-signal or simulcast radio environments, with the same HomePatrol database and zip-code programming as Uniden's easier scanners.
Rather than requiring manual frequency entry, the SDS100 loads its coverage from a zip code or GPS coordinates and pulls from a weekly-updated HomePatrol database of known US and Canada radio systems. That is what separates it from older scanner designs that ask an owner to hand build every talkgroup before it can be used.
- HomePatrol database with weekly updates
- True I/Q receiver for simulcast and weak-signal decode
- Zip code or GPS based location scanning
- JIS 4 rugged, weather resistant housing
Who it's for
Suits listeners in areas with tough RF conditions, overlapping simulcast towers or weak signal pockets, who want a handheld that decodes digital trunked systems without manual programming. Casual listeners who only want a basic scanner for one small town may find it more capability than they need.
Pros and cons
- Decodes digital simulcast and weak-signal traffic other scanners miss
- Zip code or GPS based setup skips manual frequency entry
- Customizable color display per field
- Rechargeable battery charges over any USB port
- GPS receiver for automatic location reselection is sold separately
- Database coverage limited to US and Canada systems
Performance notes
The True I/Q receiver captures the full signal waveform in three dimensions rather than just amplitude, which is what lets it correct errors and recover audio in simulcast and weak-signal conditions that defeat simpler digital decoders. Location-based scanning narrows the active system list to what is actually nearby, using either a manually entered zip or postal code or a connected GPS receiver, sold separately, that keeps the selection current while traveling.
