Amateur Radio satellite HO-68 - operating schedule
Alan Kung, BA1DU has released the latest operating schedule for the amateur radio satellite HO-68 covering January 3-10.
HO-68, also known as Xi Wang 1 (Hope 1), was launched on December 15. It's linear transponder is proving very popular and provided hundreds of SSB and CW contacts over the Christmas-New Year holiday period.
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.
Newcomers to amateur satellites will find the article 'Getting started on Amateur Radio Satellites' by John Heath G7HIA is well worth reading, see http://www.uk.amsat.org/content/view/408/168/
