RadScan Support

Remote control and live audio for the Uniden SDS200, on iPhone and iPad.

Questions, problems or ideas: radscan@enetworx.net. Say which iPhone or iPad, its iOS version, and your scanner's firmware (RadScan shows it under Settings › Scanners).

The app's own Help (Settings › Help) covers every screen in more detail.

What you need

• A Uniden SDS200 connected to your network (Ethernet), and your iPhone or iPad on the same network.
• iOS or iPadOS 18 or later.
• For the waterfall: Uniden's Waterfall upgrade on the scanner.

RadScan can't find my scanner

• Join the same Wi-Fi network as the scanner.
• Allow Local Network access: iPhone Settings › Apps › RadScan › Local Network.
• Or add it by address: Settings › Scanners › Add Scanner. The scanner shows its address under Menu › Settings › LAN Settings.

No audio, or "Audio in use or stuck"

The SDS200 streams to one listener at a time. If another phone or app is listening, stop it there first. If nothing else is listening, the scanner's audio server may be stuck: RadScan can reboot the scanner to clear it (Settings › Audio › Reboot scanner if audio gets stuck), or reboot it from the scanner itself.

The waterfall says my scanner needs an upgrade

Every SDS200 has the waterfall built in, but Uniden keeps it switched off until the scanner has their Waterfall upgrade, entered on the scanner itself. RadScan has nothing to sell or unlock for it. You can try the waterfall on the Virtual Scanner.

Free trial and unlock

Every feature is free for 5 days. After that, connecting to your scanner needs a one-time unlock: no subscription. The Virtual Scanner is always free. Bought it before, or on another device? Settings › RadScan › Restore Purchase.

Try it without a scanner

The Virtual Scanner is an SDS200 simulated inside RadScan, with fictional channels and live audio. Start it from the first screen or from Settings › Scanners.
