Radio amateur Professor Sir Martin Sweeting G3YJO, was the guest on the Radio 4 show The Life Scientific that was broadcast on Tuesday, April 20.
Martin Sweeting G3YJO pioneered the original SmallSats revolutions with the UOSAT-1 and UOSAT-2 spacecraft that carried amateur radio payloads and launched in the early 1980’s. They led to the founding of Surrey Satellite Technology Ltd (SSTL) of which he is Executive Chairman.

On April 4, AMSAT-DL announced the opening of the QO-100 NB satellite transponder to general contest operation in the upper mixed-mode range. This weekend (April 10-11) will see the Yuri Gagarin contest.
The contest area on the QO-100 geostationary satellite NB transponder for both CW and SSB is:
Uplink area 2400.370 – 2400.490 MHz
Downlink area 10489.870 – 10489.990 MHz
Of course, the usual QO-100 NB transponder guidelines also apply here. Therefore, the bandwidth should still be limited to 2.7 kHz and the transmitting power should be reduced to the necessary level, i.e. only as much power as necessary should be used.
These data were collected by more than 50 stations in the world via the UVSQsat decoder software. The software allows to send the data to the AMSAT-F and Satnogs databases. The continuous reception of telemetry is valuable to the project team that is piloting the satellite.
Although the downloading of large amounts of data is done over Europe, this also took place over Japan with the help of Japanese radio amateurs.
It is noted that a new version of the UVSQSAT Decoder software is available with new features (new ASCII telemetry decoded, performance improvement,..)
The commissioning phase has been successfully completed. Now the UVSQsat project team with Radioclub F6KRK and AMSAT-Francophone will conduct further tests on the transponder to ensure that it can be operated over a period of several days without taking any risk to the satellite.
For this we are looking for volunteer radio amateurs to participate in these tests on all continents. If you are interested contact AMSAT-Francophone, email amsatf<at>amsat-f.org
The Soyuz‑2.1a LV was launched from Baikonur in Kazakhstan on March 22, 2021. The following satellites, operating in frequency bands allocated to the amateur satellite service have been coordinated by the IARU Satellite Frequency Coordination Panel:
