Es’hail-2 / QO-100 Teleport Initiation Day

February 9, 2019 Off By Peter Gülzow

02/06/2019 Following the successful launch of Es’hail-2, Es’hailSat’s new teleport will be formally inaugurated on February 14, 2019.

This will also be the occasion to officially launch the two amateur radio transponders of Qatar OSCAR-100, the first geostationary P4-A satellite from Qatar. The opening ceremony will be performed by His Excellency Abdullah bin Hamad Al Attiyah, former Deputy Prime Minister of Qatar. A71AU is also the chairman of the Qatar Amateur Radio Society (QARS) and initiator of the first Qatari amateur radio satellite

A squad of the AMSAT-DL P4-A team, consisting of Chairman Peter Gülzow DB2OS, Achim Vollhardt DH2VA and Thomas Kleffel DG5NGI, is on its way to Qatar to set up and commission the P4-A ground segment at the Es’hailSat ground station. This includes LEILA and the DVB-S2 DATV system, as well as a club station for SSB radio operation under the callsign A71A. A backup station will be installed at the QARS in Doha. The AMSAT-DL ground station at the Bochum observatory is also ready to receive and transmit. Later, radio operation via Qatar-OSCAR 100 will also be carried out here under the callsign DL50AMSAT.

Only after the official release ceremony on February 14, the transponders will be released for general radio operation by radio amateurs worldwide.

During commissioning, we expressly ask you to refrain from any transmission attempts!

Some tests will be carried out by both the SCC in Qatar and Bochum in Germany to measure both transponders and calibrate the ground equipment.

Please also note the transmissions of the beacons in the NB transponder. On the DATV beacon of the WB transponder, a video of Es’hail-2 will be broadcast in a continuous loop in DVB-S2 format on the opening day.

Further, it is urged to refer to the rules of play as formulated under the Operating Guidelines for the NB transponder and WB transponder. Please keep to the band limits for the NB transponder as specified by the upper and lower beacon! Later adaptation and possible upward expansion may be considered after initial experiments.


Once again: Please no uplink attempts until the transponders are officially released by QARS!


We appeal to patience and Ham Spirit: any disruptions during commissioning and on opening day could result in further delays to the official release.
