(1)CubeSats of Japan
Two CubeSats XI-IV and CUTE-I were launched 30 Jun 2003,
14:15:26 UTC+2, by Japanese Universities,
'XI-IV' : Tokyo University
'CUTE-I' : Tokyo of Institute of Technology University
Sat. Uplink Downlink Beacon Mode
XI-IV . . 436.8475 1200bd CW
XI-IV . . 437.490 1200bd FM Packet AX.25
CUTE-I . . 436.8375 1200bd CW
CUTE-I . . 437.470 1200bd FM Packet AX.25(or SRLL)
This SRLL is the protocol only using in 'Tokyo of Institute of
Technology University'.
(2)Correct Keps !

(5)Information
XI-IV works for CW, FM Packet telemetry, and Image.
When this pass within 10min, only CW mode over Japan.
When this pass over 10min, CW mode 3min after AOS and 3min befor LOS,
and FM Packet always between 3min after AOS and 3min befor LOS.
CUTE-I works for CW, FM Packet telemetry.
AX.25 or SRLL protocol is 1200bps, interval of 2sec, 15min over Japan.
This SRLL is the protocol only using in 'Tokyo of Institute of
Technology University'.
