Professor Sir Martin Sweeting G3YJO

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.

Contests on QO-100 allowed in time for Yuri Gagarin contest

AMSAT QO-100 NB Transponder BandplanOn 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.

The Yuri Gagarin International DX Contest 2021 is dedicated to the memory of Yuri Gagarin, who realized the first human flight to space, on April 12, 1961.

It runs from 2100 GMT on April 10 until 2100 GMT on April 11, 2021, and the categories include:
• SAT Single operator – Satellite QSOs
• SAT-GS Single operator – Geostationary Satellite QSOs

Contest rules are at http://gc.qst.ru/en/section/32

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:

• Beesat‑5
• Beesat‑6
• Beesat‑7
• Beesat‑8
• FEES
• SMOG
• GRBAlpha
• KSU_Cubesat
• DIY‑1
• STECCO
• CubeSX-HSE
• CubeSX-Sirius-HSE
• Orbicraft-Zorkiy
• NanoSatC-BR2

Operating in frequency bands allocated to the amateur satellite service without IARU frequency coordination is KMSL. Additional satellites may follow.

Operating in frequency bands allocated to the amateur satellite service while the IARU Satellite Frequency Coordination Panel has declined coordination are UNISAT‑7 and WildTrackCube-Simba.

23cm band in the spotlight with regulators

The Chair of IARU Region 1 Spectrum Affairs, Barry Lewis G4SJH, reports on the meeting of the ITU‑R Working Party 4C (WP4C) on February 15-19 which discussed the amateur radio allocation at 1240-1300 MHz.

On the IARU Region 1 site he writes:

During the week February 15–19, the preparatory work for WRC-23 agenda item 9.1b continued in ITU‑R Working Party 4C (WP4C). The WRC agenda item has initiated technical studies on coexistence between the radio navigation satellite service (RNSS) and the amateur services in the 23cm band. As usual, the IARU participated in the meeting and delivered key information on amateur activities in this important microwave band. This information is vital to ensure the amateur services are realistically represented in the studies as they move forward.

It remains vital that national amateur communities present their views on the importance of this band to their national regulators in a consolidated and consistent manner.

To assist with this the IARU-R1 is developing supporting material that member societies can refer to when addressing the topic with their national regulator.

The work on this topic will continue throughout the year and beyond both in ITU‑R and in the regional telecommunications organisations and the IARU is committed to ensure every organisation understands the amateur position on this important microwave band.

First QO-100 satellite contact from Indonesia

Indonesia’s national amateur radio society, ORARI, reports on the first contacts from Indonesia via the Qatar-Oscar-100 geostationary satellite transponder that took place on Thursday, January 27, 2021. Those involved were Farid Farhan YC1HVZ, Remco den Besten PA3FYM and Rene Stevens PE1CMO.

ORARI’s report says a team from the Telkom University Telecommunication Engineering Student Association (HMTT) led by Farid Farhan YC1HVZ, succeeded in conducting the first contact from Bukit Moko (Grid square OI33UD), Bandung, West Java with a satellite elevation of 0.8 degrees at an altitude of 1200m+.

Over several months Remco den Besten PA3FYM, and Rene Stevens PE1CMO had helped Farid Farham YC1HVZ get equipment operational for use on the QO-100 satellite which has an uplink in the 2.4 GHz band and a downlink in 10.45 GHz.

Farid’s location in Bandung is on the edge of the satellite’s footprint and he didn’t have a clear view to the horizon so Farid had to travel to a location in the hills of Java to get an unobstructed path to the satellite which had an elevation of just 0.8 degrees.

An attempt on Monday, January 24, was unfortunately unsuccessful and Farid YC1HVZ returned to the hill on Thursday, January 27, for a test with Remco PA3FYM and Rene PE1CMO. At about 07:40 GMT they heard the first signals from YC1HVZ but Farid couldn’t receive the QO-100 signal. It’s rainy season in Indonesia, which makes it much harder – the 10 GHz downlink has to get through the heavy rain showers which attenuate the signal.

After a few tests conditions improved and Farid heard his signal coming back from the satellite and by 07:50 GMT it was possible to make a two-way contact. Rene PE1CMO was the first to receive Farid and the first who Farid received but it was Remco PA3FYM who made the first complete contact exchanging signal report, call and locator, after which Rene has a QSO with Farid. Unfortunately the signal in Indonesia then dropped due to clouds and rain but later it came back and YC1HVZ made six more contacts. Farid hopes to try that location again or go to a location on the beach on the west coast of Java for a DXpedition.

Congratulations to Farid, Remco and Rene.
