Ham Imaging

Ham Imaging is the picture side of amateur radio. Hold your phone to any receiver's speaker and watch slow-scan television pictures decode live, or transmit your own with your callsign printed on them — no interface box, no cables, no computer.

RECEIVE
• Live SSTV decode straight from your radio's audio through the device microphone
• Automatic mode detection from the VIS header — leave it on Auto and the picture just appears
• 20 modes decoded and encoded: Scottie 1, 2, 3, 4 and DX; Martin 1, 2 and 3; Robot 12, 24, 36 and 72; PD 50, 90, 120, 160, 180, 240 and 290; and Wraase SC2-180
• A live tuning meter and signal-confidence readout so you can peak the audio before the picture starts
• Slant correction for the small clock differences that make a picture lean
• The picture paints in as it arrives — you do not have to wait for the end of the frame

TRANSMIT
• Send any photo from your camera or gallery as an SSTV picture
• Optional overlay printing your callsign, grid and a free text line onto the image
• Pick the mode to suit the band and the time you have
• A progress bar tracks the transmission, and you can cancel at any point
• Putting a signal on the air stays your decision — the app makes the tones, you key the radio

GALLERY & LOGGING
• Everything you receive or send is kept together on the device with its mode and UTC time
• Share a watermarked copy anywhere
• Clean export — a plain copy at 800 px, exactly the format ARISS asks for in award submissions
• Copy an ADIF line to paste an SSTV contact straight into Ham Logging or your desktop logger
• Delete a single picture or clear the whole gallery. Nothing is ever uploaded

BUILT FOR THE SHACK
• Works fully offline — decoding and encoding never need an internet connection
• Light and dark themes, adjustable font size, weekly tips and in-app version history
• Your callsign and grid stay on your device
• No account, no ads, no analytics and no tracking

PERFECT FOR
• Operators working the HF SSTV picture nets
• Anyone chasing ISS / ARISS SSTV events and award submissions
• Shortwave listeners who want to see what those warbling tones actually are
• Newcomers who want to try SSTV without buying an interface
• Clubs demonstrating amateur radio to visitors and students

PRIVACY
• Your callsign, grid and email are stored only on your device.
• No account, no sign-up, no ads, no analytics SDKs, no advertising ID and no tracking of any kind.

Rig control (CAT): Ham Imaging reads your radio's frequency over your network, Bluetooth LE, a USB cable or classic Bluetooth, and can key it with CAT PTT if you choose. It never changes your frequency or mode.

Hunt starts with Their CQ and a Listen button. Settings has QSO Management: view past contacts, export them as ADIF or JSON, clear them. A contact can be corrected before export. About has Licences & Notices.
