2E0HTS Working the OSCAR-7 Satellite

A video from Simon 2E0HTS shows him working F6HRO and DG1EA via the amateur radio satellite OSCAR-7 which was launched in 1974.

His new assistant is showing good radio com skills especially rotating and elevating the satellite antennas.

SumbandilaSat beyond repair



The defenceWeb site reports:

South Africa’s second satellite, SumbandilaSat, is no longer fulfilling its main purpose due to technical problems and is essentially beyond repair, its maker SunSpace says.

Rob Olivier, head of Business Development at SunSpace, told defenceWeb that although contact can still be made with the satellite, it cannot capture images and is thus “not fulfilling its main purpose”.

He said that chances of repairing the satellite are virtually zero and that SunSpace has moved on to other projects.

SumbandilaSat was damaged during a solar storm in the June last year. The power supply to SumbandilaSat’s onboard computer stopped working and the satellite stopped sending back images.

Read the full story here.

In addition to its primary imaging mission SumbandilaSat (SO-67) carries an amateur radio voice beacon, parrot repeater and VHF/UHF FM repeater.

Mike Rupprecht DK3WN has made available software to decode the telemetry beacon of RS-39  (435.315 and 435.215 MHz) .

In Google English the software description reads:

Very simple tool for decoding the CW telemetry and display of telemetry values ​​of Chibis-M (RS-39).

The input of the received telemetry values ​​are in the respective fields U.S., IBS, Uzun, iSun, ITXA, ITXB, TTXA, TTXB, TNAP, TAB, MSEP, MCON, SMA, SMB, and MRXA MRXB. The converted value is displayed immediately. All values ​​are checked for plausibility, one differing from the standard value is displayed with red background. Normal telemetry values ​​have corresponding hardware box with a green background.

With the Save button, the currently displayed telemetry values are saved ​​in a file.
