Description

DigiDecoder is a universal ham radio digital modes decoder and encoder. Use the built-in microphone or connect an audio cable directly for better input quality. One app for all the signals! The correct digital mode is automatically recognized and decoded in real time with an animated waterfall display. Quickly encode and send beautiful SSTV images, plus CW, FT8, and Packet messages. Bluetooth and network TNCs for Packet are supported as well. Try DigiDecoder free for 7 days. After the trial, continue with an affordable monthly subscription, or unlock lifetime access with a one-time purchase (a few months' worth). Nothing is charged during the trial and you can cancel anytime.
