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.

Recent changes:
Trim a Recording — the Tools panel now takes an audio file as well as a video. The app marks where the SSTV headers are and lists them with their modes and times; you place the edges by dragging, typing them, or zooming in on either end.
Pictures are now stamped with when you received them, not when you decoded them. From Files opens the file browser properly, and a recording too long to read in one go is offered to Tools.
