Wiki & help

Get on the air,
or get us the log.

Two short guides and one long one. The first walks you through running JTTYAF from first launch to a logged QSO. The second explains the mode from the tones up. The third shows how to capture a debug log and file a bug report we can act on.

Want the mode itself explained?

The JTTY page covers the waveform, the 59-symbol frame, CRC-12 and the K=10 tail-biting code, the message grammar, chaining, the receiver and the preliminary frequencies — everything the clean-room codec implements. For Q&A-style answers (pricing, supported radios, the FT8AF relationship) head over to the FAQ.

Stuck somewhere the wiki doesn't cover?

Field reports from real on-the-air use are the most useful thing we get. Open an issue, tell us what happened, drop in a log if you have one.
