 According to the IF Matrix telemtry from Orbit #249 the L band uplink was
 not being matrixed (is that a word? HI) through LEILA.  If memory serves me
 right that is the way it has been since LEILA was turned on ...

 What effect would that have then on the overall S downlink if L band
 stations were hitting the transponder hard and U band stations were being
 controlled by LEILA?

  In this scenario would the un-LEILA-ed L stations overwhelm the U
stations?

 Can U and L be matrixed to LEI-1 at the same time?  Is that why there are
 LEI-1 and LEI-2?

 Thanks in advance to who ever can take a crack at answering these
questions!

 Peace & 73,
