## What is FT8 Decoder?

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.

## Key features

- Decodes FT8 8FSK modulated signals
- Processes external audio or SDR sound
- Supports standard callsigns and 13-character messages
- Generates FT8 message audio

### 1/5 — Fehlerhaft?

*2025-09-26*

Hat bei mir nicht funktioniert.

### 5/5 — Good Value and intro to Digital Modes

*2025-07-17*

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😊

### 2/5 — A little bare

*2023-03-21*

It was easy enough to decode some packets just audio coupled to the transceiver. My overall view is that it’s quite pricey for what appears to be an early demo. A polished App should provide the typical map view, and perhaps compose the log email itself.

### 3/5 — Digirig not supported

*2022-12-27*

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.

### 5/5 — Ft8d decoder

*2022-09-29*

Wow!
Just a short piece of wire on my trusty R1000 receiver and phone not even near speaker. Many decodes from across Europe on 40 metres. Tx not tried as I use wsjt-x 73 de G4BTI.

### 4/5 — Portable FT8 here we go!

*2022-08-29*

Great pocket FT8 decoder - ideal for out-and-about use with my (tr)uSDX portable HF radio transceiver. Has some basic transmit capability; hoping that auto-sequencing gets added as this app becomes more popular, along with advanced decode, allowing full FT8 operation in-the-field!
