AMSAT-OSCAR 7

Beacons
  29.502 MHz (200 mw) Used in conjunction with Mode A
145.972 MHz (200 mw) Used in conjunction with Mode B and C [low
power Mode B]
  435.100 MHz (intermittent problem -- switches between 400 mw and 10
mw)
2304.1   MHz (40 mw) Must be commanded on.  Auto off after 15
minutes.
Requires STA to operate.

Transponder I:  Mode A  (2m/10m)
type: linear, non-inverting
uplink passband:   145.850 - 145.950 MHz
downlink passband:  29.400 -  29.500 MHz
translation equation:  
downlink (MHz) = uplink (MHz) - 116.450 MHz +/- Doppler
output power: 1.3 watts PEP (start of life)

Transponder II:  Mode B (70cm/2m) and Mode C (low power)
type; linear, inverting
uplink passband:   432.125 - 432.175 MHz  *See Note
downlink passband: 145.975 - 145.925 MHz
translation equation:
downlink (MHz) = 578.100 - uplink (MHz) +/- Doppler
output power: 8 watts PEP Mode B (start of life!), 2.5 watts PEP
Mode C
*Note: Due to changes in Radio Amateur Service and Radio
Amateur Satellite Service there are questions as to
legality of US Amateurs transmitting to AO-7 on this
frequency.
