SDS Remote puts your Uniden SDS150 & SDS200 on iPhone, iPad, and Mac. See the live scanner display—system, department, talkgroup, frequency, and signal—while you work the keypad, volume, and squelch from another room. Your scanner stays where it is. You don't have to. THREE WAYS TO CONNECT • SDS200 over Ethernet, on your network • SDS150 over Bluetooth, no network needed • Through a hub: leave one device at home with your scanners and connect to it from anywhere, including on cellular WHAT YOU GET • Live display mirroring of your SDS150 & SDS200 • Save scanners by name, host, and port • iCloud sync of your scanner list across your Apple devices • Free to start with one scanner; Pro unlocks more PRO FEATURES • Remote keypad, volume, and squelch control • Live audio streaming from the scanner to your device • Listen from anywhere through a hub—the one setup where scanner audio reaches you on cellular • Now Playing on the Lock Screen and in Control Center—channel and system as they change, with play/pause from headphones or your car's controls • Choose how scanner audio shares with your music: take over, or mix and duck it while the scanner talks • Multi-view: monitor up to four scanners in a 2×2 layout • Transmission logging with optional recordings and on-device captions • Web Remote: drive your scanners from a browser on your network • Display Layout editor for building screens and sending them to the radio • Elgato Stream Deck control on iPad • Unlimited scanners IN THE CAR Mix and Duck keeps your music playing and turns it down while the scanner talks. Boost lifts quiet traffic over road noise, and Keep Display Awake stops the screen dimming on a dash mount. Built for listeners who already run a scanner on the desk—and want the same view and control from the couch, the shop, the car, or anywhere else. PRIVACY BY DESIGN We run no servers and your scanner traffic never passes through us. A hub is simply a second copy of this app on a device you own, talking directly to your other devices over a connection secured by a pairing code. Transmission logs and recordings stay on your device, and captions are produced on-device—no audio is ever uploaded. Subscriptions are handled through your Apple ID. REQUIREMENTS A Uniden SDS200 connected by Ethernet to your network, or a Uniden SDS150 paired over Bluetooth. Listening away from home additionally needs a second device left at home running SDS Remote as a hub, with Pro on both. Free includes one scanner and iCloud sync. Pro is an optional auto-renewable subscription with a free trial (see in-app details). Subscriptions renew unless canceled at least 24 hours before the end of the current period in your Apple ID settings.

Greyline FT8 is a highly portable, capable amateur radio app designed specifically for field operation with an iOS device. I designed this app because I got very used to my full-stack FT8 solution: GridTracker, WSJT-X, PSK Reporter, WRL Desktop, several browser tabs, and more. But I didn't want the bulk and weight of a full Windows PC in the field. At the same time, while there are excellent and lightweight FT8 iOS solutions out there, they were lacking features I really wanted. Greyline is everything you need and nothing you don't. It automatically locates your grid square, performs callsign and calling station DXCC lookups (internet access required), and can even show you real-time spot data from PSK Reporter. Want to adjust your directional antenna? Now you've got the info you need to do it! Greyline also incorporates automated calling features. Gatherer mode calls CQ, responds to the first reply it gets, finishes the QSO and returns to calling CQ all without your input. On the other side of things, Hunter mode listens for CQ calls and pounces on them, finishing a QSO then returning to the live band to find the next. Or, take control of the conversation yourself with standard mode. That's the experience you're already used to from WSJT-X and other digital mode apps. Some other noteworthy features are: - Intelligent automatic free frequency selection - Dynamically adjusted audio delay for virtually drift-free message timing - PSK Reporter integrated Live Spots - Direct-to-QRZ, WRL and private Cloudlog logging and ADI export - Configurable waterfall settings - CQ addendums - CQ filtering for contesting and general courteous operation - Configurable retransmissions - Intelligent log recovery (didn't get that last 73 but want to log the contact anyway? Now you can!) - Log import and export - Antenna tuning - POTA Autospotting - One touch POTA activation and POTA.app-compatible ADIF export - Multiple POTA activation support - And so much more! Greyline uses audio VOX and not serial PTT. Most radios support this with simple cabling or an audio interface like a Digirig.
