In the years ahead, it is possible that you may hear OSCAR-11, by accident, when tuning round the frequency. If you are able to record the satellite on audio tape or as a WAV file (not MP3), please do so, as it is unlikely that it will be heard on the next pass!

OSCAR-11 celebrated its 24th birthday on 01 March 2008. It was designed, built and launched, within a time scale of six months, using commercially available components. Congratulations to Professor Sir Martin Sweeting G3YJO, his team at the University of Surrey and associated groups of radio amateurs, for their magnificient achievement.

This report covers the period from 21 January to 17 February 2008, overlapping the previous report by a few days, to include the two periods of continuous operation.. The satellite was heard from 22 January to 01 February and from 11 February to 15 February.

This report covers the period from 19 December 2007 to 26 January 2008. After two months of silence from 20 November, when eclipses started, the satellite resumed transmissions on 22 January 2008. This was three complete 20.7 day watchdog cycles after the satellite switched off. At the time of writing signals are consistantly strong, although the polarisation is very variable, with a cycle time of around 20 seconds, causing deep fading if the antenna polarisation is fixed. This suggests that the satellite may be tumbling.

During the period 15 November to 19 December 2007 no signals have been received from the satellite. No reports of reception have been received.

During the period 22 October to 15 November 2007 no signals have been received from the satellite. However, Thomas HB9SKA has reported hearing the satellite on 27 October, 18:00 UTC pass.

During the period 27 September to 22 October 2007 the satellite has been heard from 06 October to 08 October. The beacon switched on as expected, on 06 October, but prematurely switched OFF sometime between 08 and 09 October. Signals were weaker than usual.

OSCAR-11 is back! During the period 31 August to 27 September 2007, the satellite's 145.826 MHz. beacon has been heard from 16 to 26 September. The switch-on date was later than expected. The solar eclipses finished on 20 August, and previous observations had suggested that the duration of sunlight after 10 August would be sufficient to support continuous operation. However, at the end of last year's eclipse season, some erratic behaviour was also observed.

During the period 15 July to 31 August 2007, The satellite has remained silent. Eclipses finished on 20 August. Previous observations indicated that anytime after 10 August there would have been sufficient solar power to support continuous operation.

During the period 15 May to 15 June 2007, no signals have been received from the satellite's 145.826 MHz. beacon. I have not received any reception reports.
