Map of Svalbard showing the QO-100 station location
A DXpedition to Svalbard (78° North) is planned for April 19-26 with the callsign JW0X. In addition to the five HF stations (FT8/FT4/RTTY/SSB/CW) the team will activate the first QO-100 satellite DX Station callsign JW100QO April 22-24.
Making the first ever QO-100 calls from Svalbard is the biggest challenge of this DXpedition. ON4CKM Cedric, ON4DCU Patrick and ON5UR Max will make a rugged snowmobile ride of almost 100 km in temperatures of -20° – 25° Celsius to reach their goal. Kapp Linné is the only place in the area that allows a view of the QO-100 satellite at only 3° above the horizon. Svalbard also lies on the edge of the satellite area (footprint), which makes the challenge even greater. We want to give as many radio amateurs as possible the opportunity to work this first QO-100 DXpedition. For this unique challenge we also have a special callsign JW100QO.

Ian GM3SEK is giving an online talk on the application of the RSGB-Ofcom Calculator to Microwaves and QO-100 satellite operation on Saturday, October 16, at 1230 GMT (1:30pm BST)
John G3XDY, Secretary UK Microwave Group, writes:
As I expect you are aware, UK stations must have Electromagnetic Field (EMF) assessments in place for operation above 110 MHz from 18th November 2021. Some RSGB guidance on EMF is here:
The RSGB has been developing a tool that incorporates the Ofcom EMF Calculator but extends the models to include single and multiple Yagis plus various sizes of dish antennas, and takes account of the directivity of the antenna.
Ian GM3SEK, a key member of the team that developed the spreadsheet tool, will be talking about its application to Microwaves and QO-100 operation on 16th October at 13:30pm, in a joint BATC/UK Microwave Group presentation during the BATC Convention.
Registration is not required, to view the talk just go to https://batc.org.uk/live/cat21
Full details of the BATC CAT21 program are available here
This is an important topic for all that operate on VHF and above, and Ian will dispense invaluable practical advice on how to assess your dishes and Yagis in the microwave bands. Not to be missed!
AWI Neumayer Station III Antarctica – image from AMSAT-DL
AMSAT-DL reports the antenna used by DP0GVN in Antarctica for the QO-100 geostationary satellite amateur radio transponder is completely destroyed.
According to the Alfred-Wegener-Institute (AWI), a severe winter storm hit Atka Bay (Antarctica) at the end of last week. At Neumayer Station III, about 20 kilometres away, wind speeds of max. 94.9 knots (175.7 km/h) were recorded as a minute average during the night from 13 to 14 August. The strongest gust was 112 knots (207 km/h). This is by far the highest wind speed in recent years.
Unfortunately, the satellite antenna for the geostationary QO-100 amateur radio satellite was also completely destroyed during the storm, despite the weatherproof radome, so no school contacts with DP0GVN can take place until further notice. AMSAT-DL and AWI hope to erect a new antenna early next year, in particular to continue the very successful contacts with schools.
The RSGB has announced that their popular weekly GB2RS news broadcast will now be available via the QO-100 amateur radio transponder on the geostationary satellite Es’hail-2.
QO-100 provides continuous coverage from eastern Brazil to as far west as Thailand. There are two amateur transponders, one for Narrowband modes such as SSB and FT8 and the other for digital amateur television (DATV).
The RSGB website says:
“GB2RS can now also be heard via the QO-100 amateur radio satellite. The transmission is provided by Keith, GU6EFB at 0800UTC, using upper sideband on 10489.900 MHz, which is in the mixed-mode section of the narrowband transponder. QO-100 is a geostationary satellite with a footprint that covers Europe, Africa and India, so this news bulletin is a specially-adapted international version. The RSGB would like to thank AMSAT-DL for their kind cooperation in making this broadcast possible.”
If you do not have 10 GHz receive capability you can still listen to the broadcast on the AMSAT-UK and BATC WebSDR located at Goonhilly, see

Dave Crump G8GKQ
At the RSGB AGM held on Saturday, April 24, 2021 the Society awarded the Louis Varney Cup for advances in space communications to Dave Crump G8GKQ.
Dave accepts this award as Chair of the British Amateur Television Club. His leadership of the BATC community, both in the UK and overseas, has been instrumental in enabling the QO100 satellite wideband transponder to be fully utilized with many new DATV systems being developed since the launch of the spacecraft.
This award acknowledges the exciting and significant contributions made by many members of the BATC, both in terms of software and hardware.

Info on the QO-100 Geostationary satellite transponders
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.

• SAT Single operator – Satellite QSOs
• SAT-GS Single operator – Geostationary Satellite QSOs
