OSCAR-11 REPORT

31 August 2007

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.

Owing to the lack of accurate timings, it is impossible to predict when sustained beacon operation will restart, although this is expected any day now. When the beacon starts it is expected to operate 10 days ON followed by 10 days OFF.

The satellite is now in continuous sunlight, and this will continue until 14 November, when a short eclipse season starts.

I have received one reception report, from Jim G3WGM, who heard weak signals at the end of a pass on 01 August. Many thanks JIM.

The Beacon frequencies are -

VHF 145.826 MHz. AFSK FM ASCII Telemetry

UHF 435.025 MHz. OFF

S-band 2401.5 MHz. OFF
