FT8 SSTV CW Packet JS8 Decoder

Features & Capabilities

Automatically identify, decode and encode amateur radio digital modes. Supports SSTV, Packet, RTTY, CW, FT8, FT4, JS8 and Olivia with real-time waterfall display.

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.

User Reviews

This is a basic app for decoding a wide range of digital signal types, and includes exchange protocol control for modes such as FT8. It will generate and send the digital modes, and key the radio via various PTT types—but does not have CAT control. There is no apparent direct log integration with RUMLOG or others. Transmitting is via the “Encode” tab,, hiding the waterfall. The waterfall does not appear to work at all, presumably a bug. This app’s strong suit is autodetecting and decoding a very large number of digital encoding types. Radio control and system integration, less so.

Caution nowhere either here or on the website does it say that there is a short free trail and then you’ll be forced to subscribe or buy. It mentions in app purchase but that usually implies some additional functionality over a free base that you pay for. This is tbe worst kind of deceitful marketing. Shame on you developer. Please reward him by not downloading this app.
