New digital mode announced

| April 26, 2019

Joe Taylor, K1JT has announced a new digital mode, FT4, which is 2.5 times faster than FT8 and is an experimental digital mode designed specifically for radio contesting.

FT4 can work with signals 10dB weaker than needed for RTTY, while using much less bandwidth.

The message formats are the same as those in FT8 and encoded with the same low-density parity check code.

Transmissions last for 4.48 seconds, compared to 12.64 for FT8.
