AO-7 downlink again at 10m
AO-7 is the only satellite, through which it is also possible to work in mode A. A longer time seemed, that circuit, Accessful on -board transponder modes do not work and satellite remains permanently switched to fashion B (435/145 MHz).
Recently, AO-7 has again switched to fashion and, that also allows an average equipped station to follow the DX connections with the easy equipment.
Operating mode can be detected by active beacon. In case, that is heard a lighthouse at 29,502 MHz (+/- doppler) is the QRV transponder in fashion and. The stations stay around medium frequency 29,450 MHz, for which uplink is 145,900 MHz (+/- doppler). Recently, RX1AX was also hosted at the transponder. Due to the disadvantageous orientation of the Downlink antenna on AO-7, the signals are relatively better, When AO-7 is located in the north. About 100W ERP is required for uplink.
