Uniden USDS100

Uniden Australia launch a local variant of the Uniden America SDS100 which was announced around March 2018 and released around June 2018 to the US and Canadian markets.

Uniden creates another first with its new highly engineered digital scanner USDS100 True I/Q Scanner, the first digital scanner to incorporate Software Defined Radio technology to provide incredible digital performance in even the most challenging RF environments. This flexible scanner will suit your everyday needs and maximising your capabilities wherever you go.

Digital Programmable True I/Q Scanner

  • True l/Q Scanning Receiver design for improved digital performance in simulcast areas
  • Rugged /Weather Resistant JIS4 Construction
  • Li-Ion Battery
  • Improved Ul with 3 contextual soft-keys that change function based on the current operation
  • Customisable Colour LCD: User can modify colour and what is displayed in each display field

Customisable Colour Display


Water Resistant (JIS4/IPX4) – Resistant to dust and damage caused by splashing water from any direction (when all jack covers are in place).

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.

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.

Favorites Scan – Allows you to organize your Systems into Favorites Lists.

microSD card (provided – 1 GB up to 32 GB supported) – For storing Favorites Lists, Profiles, all your settings, Discovery sessions, and recording sessions.

GPS Compatible – Connect to a GPS receiver (not included) for precise system selection and continuing reselection when you travel. The scanner will automatically select what to scan based on your current location as provided by an external GPS unit.

Range Control – Lets you set how far out from your current location the scanner will search for channels in Favorites Lists.

TrunkTracker X Operation – Scans APCO 25 Phase 1 and Phase 2, X2-TDMA, Motorola, EDACS, and LTR trunked systems, as well as conventional analog and P25 digital channels. Optional upgrades add multiple types of NXDN and DMR trunking, as well as EDACS ProVoice decoding.

Instant Replay – Plays back up to 240 seconds (4 minutes) of the most recent transmissions. Audio Recording – Capture transmissions for later playback.

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.

Multicolor LED Alert – The alert LED with 7 colors, Blue, Red, Magenta, Green, Cyan, Yellow, or White, can be used with your Custom Alerts.

Trunking Discovery – Monitors system traffic on a trunked radio system to find unknown IDs and automatically records audio from and logs new channels for later review and identification.

Conventional Discovery – Searches a range of frequencies to find unknown frequencies and automatically records audio from and logs new channels for later review and identification.

Scan by Service Types – Scan your channels by Service Type i.e. Fire, Police, Railroad, etc.

Multi-Level Display and Keypad light – Makes the display and keypad easy to see in dim light with multiple backlight levels.

Temporary or Permanent Avoid – For Systems/Sites/Departments/Channels.

System/Channel Number Tagging – Number tags allow you to quickly navigate to a specific Favorites List, System, or Channel.

Start-up Configuration – You can program each of your Favorites Lists with a Startup Key (0-9) so that when you power up the scanner and press the key number, just those Favorites Lists assigned to the key will be enabled for scan.

Close Call© RF Capture Technology – Lets you set the scanner so it detects and provides information about nearby radio transmissions. Close Call Do-not-Disturb checks for Close Call activity in between channel reception so active channels are not interrupted.

Broadcast Screen – Allows the scanner to ignore search and Close Call hits on known broadcast frequencies. You can program up to 10 custom frequency ranges that the scanner ignores.

Fire Tone-Out Standby/Tone Search – Lets you set the scanner to alert you if a two-tone sequential page is transmitted. You can set up to 32 Tone-Outs. The scanner will also search and display unknown tones.

PC Programming – Use the Sentinel software to manage your scanner’s Profiles, Favorites Lists, Databases, and firmware updates.

Priority/Priority w/DND Scan – priority channels let you keep track of activity on your most important channels while monitoring other channels for transmissions.

Priority ID Scan – Allows you to set priority to talkgroup IDs.

Intermediate Frequency Exchange – Changes the IF used for a selected channel/frequency to help avoid image and other mixer-product interference on a frequency.

Individual Channel Volume Offset – Allows you to adjust the volume offset for each channel.

Configurable Band Defaults – Allows you to set the step (5, 6.25, 7.5, 8.33, 10, 12.5,15, 20, 25, 50 or 100 kHz) and modulation (AM, FM, NFM, WFM, or FMB) for 31 different bands.

Adjustable Scan/Search Delay/Resume – Set a delay up to 30 seconds or a forced resume up to 10 seconds for each channel or search.

Data Naming – Allows you to name each Favorites List, System, Site, Department, Channel, ID, Location, Custom Search, and SAME group, using up to 64 characters.

Duplicate Input Alert – Alerts you if you try to enter a name or frequency already stored.

Quick Keys – You can assign up to 100 Quick Keys to your Favorites Lists, Systems, Departments, and Sites.

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.

10 Custom Searches – Lets you program up to 10 custom search ranges.

Search with Scan Operation – Lets you include Custom Search ranges during scan operation.

3 Search Keys – You can assign 3 of the number keys to start a Custom Search, Tone-Out Search, or Close Call Search.

Quick Search – Allows you to start searching at the displayed frequency or enter a frequency and start searching.

Built-in Battery Charger – Allows you to charge the rechargeable batteries in the scanner from USB2 port.
