I guess I am somewhat confused here, Stacey.

The time when uplinking is possible with a K-band downlink is MA126 to
MA134.  Are you saying that those w/o K-band should not use the satellite
during this time?  Are there enough K-band users to justify this?

Also, why not just disconnect the S-band downlink during that time then?
The beacon could still be on could it not?  Or would that cause more problem
from lids trying to uplink and find their S-band signal which would of
course be turned off.  Or do those with K-band use S-band to help themselves
find the bird first before moving to K?

I just want to make sure I understand you correctly.
