Start of test operation AO-51 (Start of test operation AO-51)

Start of test operation AO-51 2.15 Start of test operation AO-51. In the next three weeks, the control stations will monitor the sources and increase the power of the UHF B transmitter, which is about 1W. Its frequency is 435,300 MHz (downlink) and since at the assumed frequency (435,225 MHz) the GO-32 satellite is also still active, it will probably be used for a long time 435,300 MHz.

The uplink frequency is 145,920 FM s CTCSS 67 Hz. The transmitter activates after receiving one second of signal on this frequency and remains activated for ten seconds after the session ends. Because of that, that the satellite does not yet rotate quite stably, there are relatively significant signal leaks. The minimum is the small directional antennas of the earth station. Because of that, that in the first days the interest in QSOs over AO-51 will be huge, listen carefully and allow others to connect as well.
