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
