Despite the fact that I haven't managed to make JT65-HF work on my laptop yet, the more I read about the JT65 modes and how people are working great DX with them, the more I'm impressed.
When PSK31 came out, it slipped into the 'almost mainstream' as a mode for people to work DX when they didn't have a big station for CW/SSB (wonder if we'll get to call them legacy modes one of these days...). PSK31 has built a great following over 10 or 12 years. I see JT65A for HF following in these footsteps.
Oh yes! Talking of legacy modes... someone who I greatly admire for a number of reasons recently posted on his Facebook status,'without CW it's just CB'.
Maybe it was a bit tongue-in-cheek - but I did laugh! What a 1980s view of the world! Sure Morse code is fun and it'll get through in many challenging conditions. I enjoy it myself and try to use it as well as I can. It's hardly the centre of the hobby or even advancement of the hobby, is it? To even suggest that without morse code that ham radio is just a 'appliance service' is pretty demeaning to people who have broader interests! And I think it's pretty demeaning to people who enjoy CB too ;-)
Anyway - have a look at these great articles from W6DTW and NW7US about JT65 - how it works and how you can use it in operation.
