[amsat-bb] HuskySat-1 TLE

[Burns Fisher]

Joe et al:  Aside from orbit changes, getting the doppler correction right
is also pretty fussy.  I noticed yesterday that I'm a bit off frequency on
the previous official keps (at TCA where things change most quickly) where
I was not when they first came out.

I don't know if they are doing their own orbit determination.  I never
heard such.  I have also not heard about when they will be doing which
experiment.
