Thanks for the return comments, Tony, and especially all your work in helping us understand these modes better. I have been looking at the data and comparing baud rate which directly relates to the length of symbol and I suspect that many of what we thought of as the most sensitive modes may,

Tony, last week there was MT63 activity on 14109 but 14106 also seems to have been used. Andy K3UK Thanks for passing that along Andy. Spot history does seem to be a pretty good indicator of mode activity. I guess it's safe to assume that only a small percentage of MT63 activity gets spotted

The reason that I use various modes is to discover those that work the best for most conditions on a given band and maintain a reasonable throughput for a specific use. The MT-63 mode seems well suited for moderate speed (50 to 200 wpm) under conditions with periodic interference where a part

Good deal Tony. I will be in out of the shack all weekend but can park the rig on say 14,106.00 1KZ long and see what happens. Trying to get ready for a DOWNPOUR from IKE. They said on last nights news that we very well may get 6.5 + inches of rain. John, W0JAB
