At some stage, since launch, the SumbandilaSat beacon was copied by the ground station in Stellenbosch but it seems to have disappeared. The reason seems unclear. It may have accidentally happened by someone sending the in-correct CTCSS tones, wiping the audio. Time is being scheduled in the acti-vation programme to reload the audio.
Testing of various other payloads is continuing. It is however ex-pected that the amateur payload will be made available in-between other op-erations. Where possible, details will be placed on the SA AMSAT website at
An Intechnet is being planned for Sunday 22 November at 19:30 CAT where various participants will be invited to discuss their experiences and share operating procedures.


Have you passed on the information to your local high school? Learners in grades 8 to 12 are invited to take part in an essay competition to cele-brate the launch of SumbandilaSat. The main prize is an Acer Notebook PC. There are also many other prizes to be won, including Symantec software as well as electronic and radio construction kits. The closing date for the competition is 30 November.
The essay should be between 1 000 and 1 500 words about the subject "How will South Africa benefit from space projects”?
Learners are urged to do some Internet research about space projects and how other nations have benefited and in their own words describe how South Africa can benefit from its entry into the space arena. Full details on how to enter can be found on .


According to amateur astronomer Jimmy Eubanks of Boiling Springs, South Carolina, the past week was a marvelous week to study the sun: "Sunspot 1 029 has put on a show every day”! Unfortunately, the show is about to end. The sunspot is moving toward the sun's western limb where it will soon dis-appear.
"As the sun rotates sunspot 1 029 towards the limb, it appears fore-shortened," notes astrophotographer and schoolteacher John Stetson of South Portland, Maine. "Foreshortening was one way Galileo proved sunspots must be on, or near the sun's surface." 400 years ago, some observers thought sunspots might be silhouettes of transiting planets or interplanetary clouds, "but transiting objects appear to be the same size and shape throughout a transit."
As sunspot 1 029 approaches the sun's limb, it could erupt and throw hot plasma into the black void of space.

Hannes Coetzee, ZS6BZP, reports that the solar activity is still at low le-vels. There was a sunspot cluster visible during the week, but it is now rotating out of view.
20 and 15 m will provide best opportunities for DX with 10 m showing signs of also livening up in the afternoons. Conditions to the east and the west will be good from the afternoons onwards. During the late afternoons and early evenings, it will be good towards Europe. In the mornings it may be possible to make contacts with Australia on 20 m. In the afternoons there are a good possibilities of contacts with the USA on 15 m. Contacts with New Zealand are going to be challenging. During the afternoons and evenings, 15 and 20 m contacts may be possible with Brazil.
Local conditions are going to be good on 40 m during the daytime. 80 m may perform well during the early mornings and late afternoons over the shorter distances. 30 m will perform well over the longer distances during the middle of the day. With summer here, 20 m is also once again becoming very useful for local, longer distance contacts. 80 m is the frequency of choice in the evenings.
Please visit for further information.
