Es’hail-2 awards at RSGB AGM

AMSAT-DL President Peter Guelzow DB2OS

At the RSGB AGM in Birmingham on Saturday, April 27, 2019 two awards were made in recognition of work related to the amateur radio transponders on the geostationary satellite Es’hail-2 / QO-100.

The prestigious Louis Varney Cup for Advances in Space Communication was awarded to Peter Gülzow DB2OS for his leadership of the team responsible for the Qatar-OSCAR-100 mission which is now in service.

The Fraser Shepherd Award for Research into Microwave Applications for Radio Communication was awarded to Dave Crump G8GKQ, Phil Crump M0DNY, Noel Matthews G8GTZ and Graham Shirville G3VZV for enabling access for all the amateur radio community to QO-100 by developing and installing a narrow band transponder WebSDR, and wide band transponder spectrum monitor.

After the award presentation Dave, Phil and Noel gave a talk on Es’hail-2 / QO-100 covering a brief history of how the project came about, an overview of equipment required to operate QO-100 and an introduction and a demonstration of the WebSDR and spectrum monitor, which allow you to listen to stations on the narrow band segment using only a standard web browser.

Graham Shirville G3VZV was unable to be present to collect the award as on that Saturday he had to attend the key IARU Region 1 VHF/UHF/uW (C5) meeting in Vienna.

One of the presentations given at the IARU-R1 meeting was Popularity of ATV in the Netherlands by Chris van den Berg PA3CRX which you can see at

Coronation station HS10KING/mm on geostationary satellite

To mark the Coronation of King Vajiralongkorn Bodindradebayavarangkun (King Rama X) from May 4-6, 2019 the Radio Amateur Society of Thailand under the Patronage of His Majesty the King will be operating a special event station

The station will be operated from the Royal Thai Navy aircraft carrier, the Chakri Narubet, in the Gulf of Thailand from May 3-6 using the callsign HS10KING/mm.

This station will be making QSOs in the 40, 20, 15 and 10 metre HF bands, on 2 metres VHF and also using amateur radio satellites, including the Es’hail-2 / QO-100 satellite.

Consequently, the May meeting of RAST will be postponed to the second Sunday of the month, and will take place on Sunday May 12 at Sena Place Hotel when applications to take the upcoming Intermediate Class examination will be available

As usual all RAST members are welcome to attend this meeting and hopefully they will be able to have a QSO with HS10KING/mm.

Sincere 73,

Tony Waltham, HS0ZDX
RAST Vice-President

Their article, on pages 18-23, describes an easy to build 2.4 and 10 GHz dish feed, using commonly available materials, for Es’hail-2 / QO-100 deployment. The feed consists of a LHCP patch antenna for 2.4 GHz and a waveguide feed for 10 GHz, to be placed in the focal point of commonly available and cheap offset satellite TV dishes with f/D’s of around 0.6

FUNcube Data Warehouse URL Change

Dave G4DPZ reports on a change to the URL used by the AMSAT-UK Data Warehouse for the FUNcube amateur radio satellites.

As part of the migration of the data warehouse to the new server, we are now redirecting all dashboard data submissions to: http://data.amsat-uk.org/
(there is no need to change your dashboard settings)
Hence, all information at http://warehouse.funcube.org/ will no longer be updated.

I will be merging the scores at http://data.amsat-uk.org/ranking
(I am at the top of the list because of data migration)

You can search for your site name or order the columns by clicking on the column header.

There have been requests for the existing style of ranking, including age colour, for each satellite. I will be implementing this in the next couple of days.

Hope you like the new site and and feedback will be welcome.
