Hi John, Jay,
Thank you for the test!
Have left about half-and-half up on 'Grabulator II' for your
delectation.
MKSK8 was nice, but the *slightest* disturbance and it
stumbled, and the latency was obvious; PSKFEC31 was
superior, at least here.
Conditions about as good as it gets: only infrequent storm
noise crashes, BIG signals, next to no fading with none of
it deep. Can we do this again under the normal grotty
circumstances, please?
Cheers,
Steve
