HO-68 operating schedule Dec 27 - Jan 2 Alan Kung, BA1DU has released this week's operating schedule for the amateur radio satellite HO-68. The communication payload includes a CW beacon and transponders for SSB/CW, FM and digital AX.25 packet operation. The linear transponder, used for SSB and CW working, has a bandwidth of 50 kHz which allows about 10-15 simultaneous contacts to take place and can sound like the 20 metre band. Due to Doppler shift the CW beacon can appear to be up to +/- 9 kHz from its nominal frequency of 435.790 MHz and you need to tune your receiver to follow it during the pass. The beacon has been received on simple antennas such as a ¼ wave ground plane but for best results try a small Yagi with about 8 elements. To reduce the effects of Doppler the SSB transponder is inverting. This means that a LSB signal on the uplink becomes a USB signal on the downlink. You don’t need much power to work through the satellite, many contacts have been made using 5 watts output. Always use the lowest power possible and ensure your downlink signal is never stronger than the beacon.
