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.

TX Factor Show: Demonstration of QO-100 satellite operation

The TX Factor show visits the National Radio Centre at Bletchley Park where Noel Matthews G8GTZ and Graham Shirville G3VZV demonstrate how to set up and operate using the amateur radio transponders on the new geostationary satellite Qatar-Oscar-100 (QO-100).

Plus, Bob McCreadie G0FGX visits the folks at Icom UK with a full review of Icom’s long-awaited VHF / UHF all-mode transceiver the IC-9700.

Watch TX Factor Show – Episode 23 (TXF023) starting at 17:46

HS10KING on QO-100 geostationary satellite

HS10KING QSL Card

HS10KING QSL Card

To strengthen the relationship between Thai and Japanese amateur radio operators representatives of the JAMSAT group of Japan have travelled to Thailand to visit the satellite ground station HS0AJ.

They will operate from the Ground Station of the Radio Amateur Society of Thailand under the patronage of His Majesty the King (RAST).

On the occasion of the coronation of His Majesty King Vajiralongkorn Bodindradebayavarangkun, HS10A (pronounced “Hotel Sierra-TEN-Alpha), as the 10th king to reign in the Chakri Dynasty, the National Broadcasting and Telecommunications Commission (NBTC), Thailand’s regulator, has authorized the special callsign HS10KING (pronounced “Hotel Sierra-TEN-KING).

There will be an opportunity to communicate with HS10KING using the QO-100 amateur radio satellite and low earth orbit (LEO) satellites that windows pass over Thailand by amateur radio stations which is similar to AMSAT Germany’s use of the special callsign DL50AMSAT using the QO-100 satellite.

RAST hence invites AMSAT amateur radio satellite operators to join in contacting the HS10KING special event station from June 22, 2019 at 10.00 UTC (17.00 Thailand time) until June 23, 2019 at 10.00 UTC (17.00 Thailand time) using SSB mode and DATV (333 – 250 KS) signals from the station HS10KING.

Please be informed and let others know of this opportunity.

Sincerely and with respect, de HS1JAN

Project Manager of JAISAT-1
