Report an issueWant 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.

8 of 25Works great for what it is. I'm having a blast. This app eliminates the need for fancy stuff. It's worth $3 for sure. 73
So far, so good.
CQ SSTV by Black Cat is one of the best SSTV apps available for amateur radio operators. The interface is clean, simple, and reliable, making it easy to send and receive SSTV images whether you’re a beginner or a longtime ham. The app performs extremely well with clear decodes, stable operation, and excellent compatibility with popular SSTV modes. What really stands out is how fast and responsive the app feels during live operation. The controls are straightforward, audio handling is solid, and it works great for portable operations, field events, and casual SSTV nets. The developer has clearly put a lot of thought into both usability and ham radio functionality. If you enjoy SSTV, especially events like SSTV Sundays or portable operations, CQ SSTV is absolutely worth downloading. Huge thanks to Black Cat for creating such a dependable and enjoyable app for the amateur radio community!
Soon as I updated my phone this App will not work. It starts then crashes every time and I paid for this App! Waisted money
Many functions work well. But it has been 7 years without update. I cannot use my camara in the app. It doesn’t support PD Tx
So the app will do what it says; it will decode sstv images from the audio streams that it hears. You can save your images in the app, but you’ll need to screenshot them if you want them in your photos. And it only hears via the microphone; it cannot use a saved audio file for input. It only decodes live over the mic. Sad that you have to buy it to find out what the limitations are.
Dear developer the App is awesome in terms of the use cases but after first use its always crashing while trying to open it, im using 16 pro max and 17 pro both has same issues, as i have purchased it for professional use - now its not worth it, please fix the issue ASAP while uninstalling and installing again i can use the app for once only.
This app makes SSTV accessible to everyone. I would rate it five stars, but it refuses to open often enough that it becomes unusable.
