It turns your phone into an amateur-radio picture station. Hold it near your radio's speaker to decode SSTV pictures as they arrive, and flip it around to transmit your own images by playing them out as sound into the rig. From version 2.0.0 it also walks you through a complete picture contact on the SSTV QSO tab, and from version 4.0.0 the Tools tab trims SSTV pictures out of a video or an audio recording you already have. It works offline — no internet and no extra hardware.
Yes — Ham Imaging is live on both the App Store and Google Play, and has been since July 2026. Use the download buttons on the app page.
Twenty SSTV modes, encode and decode: 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. On receive the mode is detected automatically from the VIS header, so you do not have to pick one.
It is the second tab along the bottom. It walks you through one complete SSTV contact using a single picture: pick a photo, say whether you are calling CQ or hunting someone else's call, then step down the ladder — each step either sends a picture or listens for theirs. Your callsign, grid and RSV report are put on the picture for you. You run the radio throughout: the app never keys your rig and never ticks a step for you. If the phone reclaims the app mid-contact, the tab picks up where you left off, and finished contacts are kept in Past contacts (the clock icon) with their pictures.
Receiving pictures needs no licence and no special gear — just your phone near a receiver. To transmit on the air you must hold a valid amateur radio licence and operate within your privileges. No dongle or cable is required; the app uses acoustic coupling to your radio.
The microphone lets it hear and decode SSTV pictures off the air. The camera and photo library let you pick an image to transmit, and save received pictures. Audio and images are handled on your device and are never uploaded to us.
On the air, amateur radio is public — anyone with a receiver can decode a transmitted SSTV image, and your callsign overlay identifies you. On your device, your gallery, your contacts and your settings stay local and are never sent to Unixeer. The app never records audio: the microphone feed is decoded as it arrives and discarded.
