• 1200bps PSK AX25 DOWNLINK: 437.051 437.026MHz SSB

• 1200bps PSK AX25 UPLINK: 145.900 145.920 145.940 145.960MHz FM

• INCLINATION: 98 degrees(angle between orbital plane of satellite and equatorial plane of earth)

• PERIOD: 100.6 minutes (the time it takes a satellite to complete one revolution about earth)

• The uplink needs a power of 10 watt with an omnidirectional 3-elements beam and a fixed elevation angle of 20 degrees. An uplink signal deviating less than 5kHz will remain within the satellite receiver passband during the entire pass.
