Description

An FT8 decoder. FT8 is a weak signal digital mode, currently very popular in the amateur radio HF shortwave bands. The ft8d app allows decoding FT8 8FSK modulated signals contained in externally provided audio or sound from an SSB radio or SDR. The app supports Level 1 decoding of messages with standard callsigns or 13 character free text messages.

The app can also generate standard FT8 message audio, so can be used to experiment with sending and receiving FT8 encoded and modulated audio. The app does NOT perform Auto-sequencing, or decode long hashed callsigns.

Good Value and intro to Digital Modes

Amazingly this little ap works as intended on both my iPhone and ipad. About as simple as you can get and excellent for occasional decoding and demonstrating😊

Digirig not supported

Sooooo, yes this program works, as in it decodes. FT8 audio, and makes ft8 noise out. So it is then up to you to get some cables and make it work with your radio. For what this costs I wish I could get my money back it was a gamble to see if it would work with a DigiRig, sadly it doesn’t. (Missed opportunity) oh well.
