Here is a digital mode from the makers of JT-9 and JT-65.. Called FT-8 (Franke-Taylor design, 8FSK modulation). A weak signal mode that is not as sensitive to JT-65/9 but definately something that will work when voice and CW will not. This is an introduction to someone who has never heard of it, or never has used JT-65 before. It may not be for everyone, but everyone should try it.
