FREQUENTLY ASKED QUESTIONS
What is SSTV?
Slow Scan Television (SSTV) is a digital picture transmission standard used by amateur radio (ham radio) operators worldwide. It enables transmission of static images over radio frequencies. SSTV is popular among radio enthusiasts for transmitting photographs via HF, VHF, and UHF radio bands.
Why Use Robot 36 Mode?
Robot 36 is the most widely adopted SSTV mode in amateur radio communities. It encodes 320x240 color images in exactly 36 seconds, providing excellent balance between transmission speed and image quality. It works reliably on all radio frequency bands and equipment.
Is My Data Secure & Private?
Absolutely. SSTV Studio processes all encoding and decoding locally in your browser using WebAssembly and Web Audio API technology. Your images never leave your device—nothing is uploaded to external servers. Complete privacy and offline capability.
Which Browsers Are Supported?
SSTV Studio works on all modern browsers including Chrome, Firefox, Safari, and Edge that support HTML5, WebAssembly, and Web Audio API. Works on desktop and mobile devices.
Do I Need Special Hardware?
No special hardware required for encoding. For receiving SSTV signals, you need a ham radio and a microphone to capture the signal from your radio's speaker output. All processing is web-based.
Is SSTV Still Used Today?
Yes! SSTV remains active in ham radio communities worldwide. Amateur radio operators regularly transmit SSTV images on HF frequencies, especially during international events and space station contacts. It's a fun and engaging mode of amateur radio communication.
