Simple dual band dish feed for Es’hail-2 / QO-100

DKARS April 2019 front coverThe April 2019 issue of the free DKARS magazine features an article in English – Simple dual band dish feed for Es’hail-2 / QO-100 by Mike Willis G0MJW, Remco den Besten PA3FYM and Paul Marsh M0EYT.

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

Spain: Authorization for 2.4 GHz operation

Es'hail-2 Qatar-OSCAR-100Spain’s national amateur radio society URE reports the regulator has agreed to allow amateur use of 2400.050 to 2409.500 MHz to access the E’hail-2 / QO-100 geostationary satellite.

A Google translation of the URE announcement reads:

Since the State of Qatar sent the geostationary satellite Es’hail-2, the first of its kind to be used by radio amateurs, to space on November 15 of 2018, the URE satellite (AMSAT) raised the possibility of requesting the Administration the free use of the entire segment granted for radio amateurs in Spain and not only segment 2316-2332 MHz.

The Administration, responding to the request submitted by the URE, has developed the present resolution, which authorizes until September 26, 2019, to the holders of radio amateur authorizations, the emission of the amateur radio satellite service from 2400.050 to 2409.500 MHz. For single-sideband telephone communications, with a maximum eirp of 1500 watts, from authorized amateur radio stations located anywhere in the national territory.

Space meeting to be streamed via ham radio geostationary transponder

Es'hail-2 Qatar-OSCAR-100The 2nd Amateur Radio Space Meeting, taking place in Nanterre, Paris, March 9-10, will be streamed live via the Digital Amateur TV transponder on Es’hail-2 / QO-100 geostationary satellite.

A Google translation of the AMSAT-Francophone post says:

AMSAT-Francophone and Electrolab have deployed a ground station to operate the QO100 transponder in DATV.

The “broadcast DATV” team led by Yannick Avelino and with the support of Evariste F5OEO has developed the station that will broadcast live the conferences of the second amateur radio space meeting March 9-10, 2019. The team was in contact with AMSAT-DL and AMSAT-UK for permission to operate the satellite during these days.

2.5 milliwatt OPERA signal via Es’hail-2 geostationary satellite

Es'hail-2 Qatar-OSCAR-100Markus Vester DF6NM successfully used the digital mode OPERA to send a 2.5 milliwatt signal on 2.4 GHz through the amateur radio transponder on the Es’hail-2 / QO-100 geostationary satellite.

Graham G0NBD writes about the contact on Digital Radio Groupsio.

On March 3, 2019, Markus started using 250 milliwatts on 2.4 GHz into a 60 cm dish pointing at Es’hail-2. The downlink signal was received via the AMSAT-UK and BATC 10 GHz WebSDR at Goonhilly in Cornwall by Peter Knol PA1SDB.

Markus then reduced power to just 2.5 milliwatts and the signal was still receiveable.

Es’hail-2 / QO-100 coverage from 25.9° East

The geostationary satellite Es’hail-2 carrying amateur radio transponders launched from Kennedy Space Center at 20:46 GMT on Thursday, November 15, 2018 and is now in a geostationary orbit at 25.9° East. The transponders should link radio amateurs across a third of the globe from Brazil to Thailand.

Following commissioning of the satellite on February 12, 2019 the Qatar Amateur Radio Society (QARS) invited radio amateurs worldwide to use the Es’hail-2 / QO-100 narrowband transponder https://amsat-dl.org/en/qo-100-nb-transponder-experimental-operation

Qatar OSCAR-100 is the first geostationary amateur radio transponder, a joint project between the Qatar Satellite Company (Es’hailSat), the Qatar Amateur Radio Society (QARS), and AMSAT Deutschland (AMSAT-DL) which provided the technical lead.

OSCAR-100 is hosted on Es’hail-2, a Broadcast Transponder Satellite owned by the Es’hailSat Qatar Satellite Company, the satellite is now in geostationary orbit at 25.9° E.

More information on the OSCAR-100 project can be found at AMSAT-DL Phase 4-A
