return link
2 VOICE
1 T/M (can get PL through "bent-pipe")
SPA3-01: s-band comm only
Ku-band PL opo[[?]]

(not planning to fly teleprinter once text/graphics works)
Ku-band contstraints: EMI on P/L (main - beam 240 V/m) - a[[?]]t program will trip-off Ku-band when 67 v/m would hit PL. Separation not a problem (beam drops off to ~ 4 v/m at 100 m)
planning groundrules: 1st 24 hrs, no KU-band?
KU & S-band together => pwr problem (>~ 2 RW)
Ku system is primarily single string
