Information
Mode B and C Uplink 432.125 to 432.175 MHz CW/LSB
Mode B and C Downlink 145.975 to 145.925 MHz CW/USB (inverting)
Mode B Beacon 145.9775 MHz (CW telemetry)
Mode C Beacon 435.100 MHz (intermittent)
Mode A Uplink 145.850 to 145.950 MHz CW/USB
Mode A Downlink 29.40 - 29.50 MHz CW/USB (non-inverting)
Mode A Beacon 29.502 MHz (CW telemetry)
Launched 15 November 1974
Status: Semi-operational
AO-7 became non-operational in mid 1981 due to battery failure . In 2002 one of the shorted batteries became an open and now the spacecraft is able to run off solar panels. For this reason it is not usuable in eclipse and may not be able to supply enough power to the transmitter to keep from frequency modulating the signal. Lately AO-7 has favored Mode B almost exclusively.
Mode A is equivalent to Mode V/A
Mode B (8 Watts PEP) is equivalent to Mode U/V
Mode C is the same as Mode B however the power is 2.5 Watts PEP
There is also a 13 cm beacon at 2304.1 MHz, however this does not get turned on as it is outside the Amateur allocation for 13 cm.
