I recently ran a RTTY contest on N1MM and had no "drops". When I set up for
the upcoming WAE RTTY test I switched back to WL. The "drops" started again.
An update on my original post and thanks to several emails, I have made some
changes in the WL/MMTTY setup under the TX tab. It appears that it has had
some effect but I'm not sure until it gets under the load of contest
activity. Tape at 11.
