Why the hold up in switching over? Is it turning in to a PSK31 ordeal where everyone goes "well, it's here first; why change?" or are some people just completely against the idea of JT9?
No, none of the above. But, IMHO, you nailed it in your first paragraph.
Sure, it's a bit of a boring mode, .....
The minimum legitimate QSO time is about 5 minutes. That's a lot of time to exchange calls, a report, and say 73. I don't see JT remaining this popular for an extended time but I guess it has appeal to those with mediocre stations. I'm tired of the mode after about 50 to 100 QSOs.
But at least you don't have to hear about the other station's old Window 95 Pentium II with 256 MB RAM....
