Contests on QO-100 allowed in time for Yuri Gagarin contest

AMSAT QO-100 NB Transponder BandplanOn April 4, AMSAT-DL announced the opening of the QO-100 NB satellite transponder to general contest operation in the upper mixed-mode range. This weekend (April 10-11) will see the Yuri Gagarin contest.

The contest area on the QO-100 geostationary satellite NB transponder for both CW and SSB is:

Uplink area 2400.370 – 2400.490 MHz
Downlink area 10489.870 – 10489.990 MHz

Of course, the usual QO-100 NB transponder guidelines also apply here. Therefore, the bandwidth should still be limited to 2.7 kHz and the transmitting power should be reduced to the necessary level, i.e. only as much power as necessary should be used.

The Yuri Gagarin International DX Contest 2021 is dedicated to the memory of Yuri Gagarin, who realized the first human flight to space, on April 12, 1961.

It runs from 2100 GMT on April 10 until 2100 GMT on April 11, 2021, and the categories include:
• SAT Single operator – Satellite QSOs
• SAT-GS Single operator – Geostationary Satellite QSOs

First QO-100 satellite contact from Indonesia

Team from the Telkom University Telecommunication Engineering Student Association

Team from the Telkom University Telecommunication Engineering Student Association

Indonesia’s national amateur radio society, ORARI, reports on the first contacts from Indonesia via the Qatar-Oscar-100 geostationary satellite transponder that took place on Thursday, January 27, 2021. Those involved were Farid Farhan YC1HVZ, Remco den Besten PA3FYM and Rene Stevens PE1CMO.

ORARI’s report says a team from the Telkom University Telecommunication Engineering Student Association (HMTT) led by Farid Farhan YC1HVZ, succeeded in conducting the first contact from Bukit Moko (Grid square OI33UD), Bandung, West Java with a satellite elevation of 0.8 degrees at an altitude of 1200m+.

Over several months Remco den Besten PA3FYM, and Rene Stevens PE1CMO had helped Farid Farham YC1HVZ get equipment operational for use on the QO-100 satellite which has an uplink in the 2.4 GHz band and a downlink in 10.45 GHz.

Farid’s location in Bandung is on the edge of the satellite’s footprint and he didn’t have a clear view to the horizon so Farid had to travel to a location in the hills of Java to get an unobstructed path to the satellite which had an elevation of just 0.8 degrees.

An attempt on Monday, January 24, was unfortunately unsuccessful and Farid YC1HVZ returned to the hill on Thursday, January 27, for a test with Remco PA3FYM and Rene PE1CMO. At about 07:40 GMT they heard the first signals from YC1HVZ but Farid couldn’t receive the QO-100 signal. It’s rainy season in Indonesia, which makes it much harder – the 10 GHz downlink has to get through the heavy rain showers which attenuate the signal.

After a few tests conditions improved and Farid heard his signal coming back from the satellite and by 07:50 GMT it was possible to make a two-way contact. Rene PE1CMO was the first to receive Farid and the first who Farid received but it was Remco PA3FYM who made the first complete contact exchanging signal report, call and locator, after which Rene has a QSO with Farid. Unfortunately the signal in Indonesia then dropped due to clouds and rain but later it came back and YC1HVZ made six more contacts. Farid hopes to try that location again or go to a location on the beach on the west coast of Java for a DXpedition.

Congratulations to Farid, Remco and Rene.

Thailand grid NK99 on QO-100 geostationary satellite

Es'hail-2 Qatar-OSCAR-100During November 26-28 HS0AJ/P will be active on QO-100 and the other amateur radio satellites from Grid Square NK99 in Thailand

A post on the AMSAT Bulletin Board says:

The Thailand’s Amateur Radio Satellite group (AMSAT-HS) has requested permission to establish a temporary station (DX portable) with the northern office of the NBTC, Thailand’s regulator, in Chiang Mai and Mae Hong Son (grid NK99) provinces in the north of Thailand during the period from November 26-28, 2020 to communicate via All LEO and MEO amateur radio satellites (including QO-100 NB) that pass over Thailand using the callsign HS0AJ/P of the Radio Amateur Society of Thailand under the Royal Patronage of His Majesty the King.

Hence we would like to notify all radio amateurs who would [be] interested in contacting stations in Thailand on its northern border of this activity. Even if the angle is as low as 0 degrees please try to contact us. We hope to meet you on all satellites frequency then.

Amateur radio satellite talk now online

AREx - Gateway Amateur Radio Exploration

AREx – Gateway Amateur Radio Exploration

On Tuesday, November 10, Dave Johnson G4DPZ gave an online satellite talk to the Mid Ulster Amateur Radio Club, the video is now available for everyone to watch on YouTube.

The talk covered the many amateur satellites in Low Earth Orbit that operate in the 145.8-146.0 MHz and 435-438 MHz satellite bands as well as the QO-100 geostationary satellite which uses the 2.4 GHz and 10 GHz bands.

Also covered were the new Inter-Operable Radio System which has recently been installed in the ISS Columbus module and Gateway Amateur Radio Exploration (AREx).

After the talk the Mid Ulster ARC @MN0VFW tweeted:
“What a talk from Dave G4DPZ from @AmsatUK this evening. Thank you to him and everyone who joined in.”

RSGB Tonight @ 8 Video – Getting started on QO-100

Es'hail-2 Qatar-OSCAR-100On Monday, July 27 Dom Smith M0BLF gave an online talk – Getting started on QO-100as part of the RSGB Tonight @ 8 live webinar series.

Dom’s lockdown project was to complete a set up for the QO-100 amateur radio transponders that are hosted on the geostationary satellite Es’hail-2. This was the first amateur radio payload to be put into a geostationary orbit and provides constant and reliable coverage for amateur voice, data and television contacts over the whole of Africa, Europe and the Middle East and even as far as Brazil in the west, and Thailand in the east.

Getting started on QO-100 is a talk in two halves: first we’ll watch the video, showing the particular set-up chosen—and there are many!—and then there will be chance for a Q&A. The equipment list can be see at https://www.domsmith.co.uk/blog/2020/07/27/rsgb-webinar-on-qo-100/

Schedule released for E2STAYHOME satellite operation

Es'hail-2 Qatar-OSCAR-100Thailand’s regulator, the National Broadcasting and Telecommunications Commission (NBTC), has issued the special callsign, E2STAYHOME, to the Radio Amateur Society of Thailand under the Royal Patronage of His Majesty the King (RAST) for use during the outbreak of the COVID-19 virus.

This is because it is very important for people to boost their immune systems to fight off germs that can enter their bodies and to reduce the chance of getting infected by the COVID-19 virus. Now, it is very important to stay home and to keep a distance of at least one metre from others, if this is possible, which is one way to help prevent the spread of the disease on a global basis.

This is a rare opportunity for ham radio operators who are interested in satellite communications to legally communicate with Thai amateur radio stations by means of the Es’hail-2 or QO-100 geostationary satellite which licensed by the Thai regulator, the NBTC, in response to requests from RAST, and using the special callsign E2STAYHOME on the evenings of each working day in Thailand and on every weekend.

The operating schedule is as follows:
Monday to Friday, 1100 – 1500 UTC
Saturday and Sunday, 0800 – 1500 UTC
all days after 1600 UTC and up to 2200 UTC Thailand has an emergency curfew in place. Please STAY HOME!!

During these times, Thai hams will be operating using this callsign on all bands and in all modes, including all satellite modes under the supervision of the Radio Amateur Society of Thailand (RAST) in an effort to help prevent the spread of COVID-19 and they will be QRV from today until July 15, 2020. QSOs with E2STAYHOME can be confirmed via Tim W. Tadsri, HS6MYW and QSL cards will be sent to all via the bureau.
