OSCAR-11 REPORT 31 December 2010

At the present time OSCAR-11 (AKA UO-11 or UoSAT-2) is now in a very stable and predictable mode of operation. There are very few changes taking place at the present time, I have therefore decided to limit the size of the monthly reports to a short status report.

The full monthly report will still be available on my website, and new listeners to OSCAR-11 should read this for further information. The URL is www.g3cwv.co.uk/oscar11.htm . This page contains a links to the longer report, a short audio clip to help you identify the satellite and a file of the last telemetry received. The website also contains an archive of news & telemetry data which is updated from time to time, and details about using a soundcard or hardware demodulators for data capture. There is also software for capturing data, and decoding ASCII telemetry.

This report covers the period from 30 November to 31 December 2010. During this time the satellite has been heard from 10 to 20 December and from 31 December. It is expected to switch-off on 10 January 2011.

Excellent signals have been reported from stations located around the world, and good copy obtained from decoded telemetry frames.

The satellite is now transmitting during eclipses, although signals are weaker at those times. This indicates that there is still some capacity remaining in the battery.

The on-board clock is now very stable. It gained seven seconds during December.

The VHF beacon frequency is 145.826 MHz. AFSK FM ASCII Telemetry

Reception reports have been received from Horatio CX8AF, John KB2HSH, Francisco PY9FP and Mike DK3WN . Many thanks for those and to everyone who posted reports on the satellite status website.

At the present time, while OSCAR-11 is operating in a predictable way, I no longer need direct reports or files by e-mail. However, could all listners continue to enter reports on the general satellite status website. This is a very convenient and easy to use facility, which shows the current status of all the amateur satellites, and is of use to everyone. Reports around the expected times of switch-on and switch-off are of special interest. The URL is http://oscar.dcarr.org/index.php
