Amateur radio use of 2400 MHz in Spain

Es'hail-2 Qatar-OSCAR-100Spain’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.

QO-100 geostationary satellite talk at Hamfest 2019

QO-100 talk by Paul M0EYT at Hamfest 2019

QO-100 talk by Paul M0EYT at Hamfest 2019

Paul Marsh M0EYT gave a presentation titled ‘All you need to know to get going on Es’hail-2 / QO-100 geostationary satellite’ at Hamfest 2019 in Dorset on Sunday, August 11.

The 50 minute talk covered satellite information, software, hardware, dish alignment and was followed by a question and answer session.

The talk proved to be very popular and attracted a large audience.

Paul has made available a PDF copy of the slides and you can download it here.

High school students in Brazil building QO-100 ground station

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.

Iceland’s IRA buys Qatar Oscar 100 and APRS equipment

Es'hail-2 Qatar-OSCAR-100The Board of Directors of Iceland’s nation amateur radio society, the IRA, has authorized the purchase of equipment to operate via the amateur radio transponder on the QO-100 (Es’hail 2) geostationary satellite.

A translation of the IRA post reads:

The Board of Directors of ÍRA recently agreed to authorize the Fund to purchase the following equipment from Microsat in Poland:

• Microsat WX3in1 Mini APRS Advanced Digipeater / I-gate (2 pcs.)
• PLXDigi – APRS Digipeater (2 pcs.)

Guðmundur Sigurðsson, TF3GS, submitted a request to the company on the APRS group. He says the equipment will seal the system and increase the quality and usability of the system, including utilizing the Motorola GM-300 terminal, which recently received eight such stations. The installation includes, among other things, installation of I-gate in Akureyri and Digipeater on Þorbjörn near Grindavík.

At the same meeting, the acquisition of QO-100 transverter from PE1CMO in the Netherlands was further authorized; “A complete transverter with a 25 MHz reference oscillator for the LNB, a downlink converter from 739 to 432 MHz and an upconverter from 432 to 2400 MHz, double filtered and a 20 Watt amplifier.” Ari Þórólfur Jóhannesson, TF1A, VHF manager of the company, negotiated a discount price for the company at Ham Radio show 2019 in Friedrichshafen.

The APRS equipment costs about 45 thous. krónur and the Oscar-100 equipment by 118 thous. krónur (with accessories and connectors). The stated price includes transportation and charges in Iceland.
