DARC reports on a Practical Seminar about the amateur radio QO-100 geostationary satellite transponders. Part of seminar fees goes to the “School stations on QO-100” project.
A translation of the DARC post reads:
Top-class seminar in the DARC office in Baunatal: On February 28, experts from AMSAT-DL e.V. gave around 40 people a detailed insight into the possibilities offered by the QO-100 amateur radio transponders on the geostationary satellite Es’hail-2.
AMSAT-DL President Peter Gülzow, DB2OS, started with a keynote speech. Workshops with four lecturers dealt with different operating modes, different hardware concepts and readily available software solutions for the PC.
Part of the attendance fee will go to the joint project of DARC and AMSAT-DL “School stations on QO-100”. Together they want to equip ten schools that already have a training call sign with a complete reception system for the narrowband transponder.
DARC and AMSAT-DL want to motivate more young people for amateur radio through the possibilities that QO-100 offers.

Elín Sigurðardóttir TF2EQ operating TF3YOTA on QO-100
Iceland’s national amateur radio society, the IRA, reports Elín Sigurðardóttir TF2EQ, launched TF3YOTA from TF3IRA’s radio room in Skeljanes on December 19.
First at 14 MHz and when the conditions disappeared it switched to the IRA’s satellite station for communication via the Es’hail-2 / Qatar-Oscar-100 satellite. Ari Þórólfur Jóhannesson TF1A, IRA VHF Manager, assisted Elina and posted, among other things, a fun video of the contacts on Facebook.
The YOTA project began last year (2018) and will be operational in December each year. It is designed to increase young people’s interest in amateur radio. The project is under the auspices of IARU Area 1 and all national amateur radio amateurs in the Region are involved (as well as national members of Regions 2 and 3).
Elín Sigurðardóttir TF2EQ, is the IRA’s youth representative and YOTA project manager together with Árni Frey Rúnarsson, TF8RN. They plan to activate the call sign on as many HF bands (as required) throughout the month, as well as contacts on the OSCAR-100 satellite.

Spain’s national amateur radio society URE reports that amateurs will be allowed to use 2,400.050 to 2,409.500 MHz for QO-100 (Es’hail-2) geostationary satellite contacts until Dec 26, 2020.
A translation of the URE post says:
At the request of the Spanish Amateur Radio Union (URE), last March the Secretary of State for Digital Advance authorized until September 26, 2019 under certain conditions and on a temporary and experimental basis the realization of emissions from the amateur service in the frequency band 2400,050 to 2409,500 MHz.
The URE has again requested the Secretary of State for Digital Advance the extension of the aforementioned administrative authorization for a period of one year.
On September 26, the Resolution of the Secretary of State for Digital Advance is approved by the resolution Authorize until December 26, 2020 to the holders of amateur radio authorizations, the realization of emissions from the amateur service in the frequency band 2,400,050 to 2,409,500 MHz., With a maximum eirp of 1500 watts and using directive antennas with a gain not less than 22.5 dBi, from authorized amateur radio stations located anywhere in the national territory to the QO-100 satellite located in the 25.9ºE orbital position of the geostationary orbit.

Students at Colégio Embraer Casimiro Montenegro Filho
High school students in Brazil are building a ground station for the amateur radio transponder on the QO-100 geostationary satellite as part of a STEM education project.
A group of eight students, from Colégio Embraer Casimiro Montenegro Filho in Botucatu state of São Paulo, are participating in all steps of the project with the help of teachers and amateur radio volunteers from LABRE/AMSAT-BR (Edson PY2SDR, Demilson PY2UEP, José PU2MJR).
The station consists of a 1.2m offset dish antenna, an Amiko L-104 LNBF, a home-made bias-t, a RTL-SDR receiver and SDRsharp software running on a dedicated computer. During the project students were exposed to several STEM topics related to radio communications, antennas, software defined radios, geostationary orbits as well as hand-on activities during the station assembly and configuration.
The students were able to successfully receive test transmissions in morse code kindly made by Roland PY4ZBZ and Fábio PY4AJ. The next step of the project is to introduce digital communication concepts, decode the BPSK engineering beacon and finally to add transmission capability to the station. In the near future, besides making contacts with other stations on QO-100, the students would also very much like to contact other schools and students in the QO-100 footprint.
