Hi Les, It is 2009. Digital evolution moves on. MT63 had a few good years of activity in the late 1990s. It was a significant step in the evolution of digital texting modes. But, alas, the popularity of MT63 on 14109 kHz USB subsided about 8 years ago. This coincided with the increasing popularity of a number of other interesting modes that eclipsed MT63.
We saw very very few MT63 QSOs in 2008 on 14109 kHz USB. 73 Bonnie KQ6XA
