Identify, decode, and encode amateur radio digital modes in real time on iPhone, iPad, and Mac.
Free 7-day trial.
Point your device at a radio and DigiDecoder identifies the digital mode in real time, then decodes the actual message.
FT8, FT4, JS8, CW, RTTY, Olivia, Packet (AX.25 / FX.25 / IL2P), and SSTV, with baud rates and variants detected automatically.
Real-time spectrogram with selectable color schemes so you can see signals across the passband.
Send SSTV images, CW, FT8/FT4, and Packet. DigiDecoder builds the audio and plays it through your transmitter, with optional PTT keying.
Call CQ, tap a decoded CQ to reply, and let the auto-sequencer run the exchange through to 73. Completed QSOs can be saved.
Transmit and receive AX.25 / FX.25 packets over audio, or connect a Bluetooth or network KISS TNC such as Mobilinkd or Direwolf.
Browse a running session log, bookmark messages worth keeping, and optionally sync your saved entries across devices via your private iCloud.
All audio processing and decoding runs on your device. No accounts, no ads. Anonymous usage analytics are opt-out and never include decoded content.
DigiDecoder automatically detects and decodes the modes below, extracting the actual message content (and the image, for SSTV), and transmits them as well. All baud rates and mode variants are auto-detected. On transmit it renders the audio and plays it through your radio with optional PTT keying; FT8 and FT4 include automatic QSO sequencing, and Packet can also go out over a Bluetooth or network KISS TNC.
