Droid SSTV - SSTV app for Android


DroidSSTV is an app for Android which lets you transmit and receive amateur radio (ham radio)  slow scan TV on your Android Smartphone or Android tablet. This communications app is a great tool for portable  slow scan TV operation. Just connect your Android phone or tablet to an HF radio (or even set it next to the radio’s speaker), tune on to an SSTV frequency, and watch the pictures scroll onto the screen. DroidSSTV supports the modes Scottie 1, Scottie 2, Scottie DX, Martin 1, and Martin 2 at this time.

The features in SSTV receiving modes include:

  • Spectrum analyzer for easy tuning
  • Auto synchronization ( auto slant correction)
  • Auto mode detect
  • VIS encoding (detects SSTV header and sets mode automatically)
  • Level bar for adjusting the audio signal
  • Auto save received pictures to SD Card.
  • Share received pictures (Email , Dropbox etc.)
To decode an image just hold your phone/tablet’s microphone close to a speaker of your ham radio receiver or transceiver. SSTV uses a 1200Hz synchronization signal as well as the luminance frequencies between 1500Hz and 2300Hz. The frequency spectrum is shown in the FFT graph. DroidSSTV will try to detect the header signal (VIS signal). If DroidSSTV can’t find the VIS code it will try to set the mode by measuring the time between the synchronization signals.

The features in the SSTV transmitting modes include:

  • Pre-load up to 9 pictures from the SD Card into  gallery
  • Adjust contrast, brightness and saturation
  • Template editor for easily overlaying templates over images
  • Macro’s for use with templates
