Want to display or send SSTV transmissions, without using a bulky computer? SSTV Pad lets you decode and display Ham (Amateur) Radio SSTV (Slow Scan TV) transmissions. Just connect your device to an HF radio (or even set it next to the radio's speaker), tune in an SSTV frequency, and watch the pictures. SSTV Pad decodes all of the popular SSTV modes, including Robot, Scottie, Martin, and more. Some modes are receive only.
Decoding of SSTV transmissions begins automatically as soon as the start of image audio signals are detected, and the image format is automatically selected. Manual control is also available for use when receiving conditions are poor. Timing signals (phase and skew) can be adjusted to compensate for mismatches with the sending station.
Received images can be saved - including automatically as they are received. You can leave the app running unattended, and come back to view all the received images. You can review saved images, as well as send them via email, and use iTunes file sharing to transfer them to your computer. You can even share them on your Facebook page, or tweet them to your followers, directly from the app! (iOS 6 and later)
You can also transmit images, taken from your saved photos or taken with your device's camera. Text, such as your callsign, can be added to the sent image.
Buy your copy right now, and start decoding and displaying SSTV transmissions in minutes. Just set your iPhone or iPad next to the radio speaker, and watch the pictures come rolling in.
Note: If you cannot see the transmit button, go to the Accessibility settings for your device and turn Button Shapes OFF. It makes the buttons too large so you cannot see them all.
Also, It is very important to have a well tuned signal of good quality, and make sure you get the audio from your radio to your device without adding additional distortion, or auto start and mode detect will not work optimally. Please see this page for tips on using the app and connecting your radio: http://www.blackcatsystems.com/ipad/iPad_SSTV_Pad_FAQ.html
You can also use Bluetooth audio devices to feed audio into your device. Please be sure to use a good quality Bluetooth device, that does not distort the audio.

Ratings and Reviews
Works great for receiving even just holding near my HT on low volume. The sliders for adjusting phase and skew tend to keep moving after you lift your finger and it throws off the image. Also there should be a way to automatically save received picture data and/or the audio files. It "auto-detected" the start of a new picture and wiped out the last one before I could save.
Nice program needs work
I have used this program successfully for several months and am generally happy with it. The basic functions I find easy to use. I use Solocator to get pictures because it puts GPS numbers on the photo automatically and I was able to type my callsign in the same font size, something I could not do in Black Cat.
this is a great app for portable use. dont have to bring bunch of wires and hardwares. It autosaves your received images to photos folder. One issue, it sometimes changes mode in a blink of an eye and right before the sstv station starts to transmit, bit annoying, so you have to keep an eye on your phone that its in the right mode. Hopefully updates will fix and add mode lock. So far it works great.
With Family Sharing set up, up to six family members can use this app.
