Judging from the number issued in recent years the FCC seem happy to issue experimental licenses for satellites in 144/435/2400 including the use of emission types that aren't covered by existing FCC amateur radio regulations. 


AggieSat4's 153.6 kbps 4 watt 436 MHz downlink using ITU Emission 
Designation 406KF7DBN might breach the bandwidth limits of an amateur 
license, its 406 kHz B/W comfortably exceeding the FCC 100 kHz limit on the band, but FCC were okay with issuing an experimental license for it.


As I read the FCC amateur regs emission spread spectrum emission modes such as CDMA can be used on all amateur bands as long as ITU emission designation symbols 2 and 3 are not both X. Such XX modes are designated by FCC as "SS" and only permitted above 420 MHz.
