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.

Digital ATV co-ordination on Es’hail-2

Narrowband DATV (150 kHz bandwidth) via QO-100 sent by Noel G8GTZ Feb 14, 2019 at 0950 GMT

AMSAT-DL has agreed to a proposal by the British Amateur Television Club (BATC) for the use of the bottom 100 kHz of the wideband transponder (10491 – 10491.1 MHz) for ATV co-ordination purposes.

The announcement on the BATC Forum says:

This is on an experimental only basis and stations must keep their power levels to a minimum and certainly not exceed power levels greater than 15dB above the noise floor as shown on the Goonhilly spectrum monitor.

This is sanctioned on an experimental only basis and AMSAT-DL reserve the right to move the WB beacon towards the band edge or implement DVB-S with a wider rolloff which would render the frequencies unsuitable for this purpose.

So another challenge but should be manageable and prove a useful facility although we do see the chat being the major tool for reports and contacts.

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

In co-operation with AMSAT-UK, the British Amateur Television Club will be operating a 10 GHz WebSDR for the narrowband segment, and a Spectrum Viewer for the wideband (DATV) segment.

Goonhilly Earth Station is supporting the project, providing hosting for the Ground Station facility at their world-famous site in Cornwall, UK.
