Snehal Vagadia VU3WHO (14), an 8th grade student of Saint Paul’s School, Rajkot, India, received the SSTV Image on February 10, 2019 at 5:33 AM UTC (11:03 AM IST).

It was good ISS pass with 56 deg elevation, strong signal were received using a 3 element Yagi antenna and a VHF HT tuned to 145.800 MHz. SSTV audio was recorded on a smartphone and later decoded with MMSSTV.

He got amateur radio licence at the age of 13 years and learnt ham activities from his father Rajesh Vagadia VU2EXP (Regional Coordinator, West India Zone, AMSAT-INDIA).

Qatar OSCAR-100 web receiver now live

Qatar OSCAR-100 web receiver now live

Qatar Satellite Company (Es’hailSat), the Qatar Amateur Radio Society (QARS), and AMSAT Deutschland (AMSAT-DL) which provided the technical lead.

OSCAR-100 is hosted on Es’hail-2, a Broadcast Transponder Satellite owned by the Es’hailSat Qatar Satellite Company, the satellite is now in geostationary orbit at 25.9° E.

More information on the OSCAR-100 project can be found at AMSAT-DL Phase 4-A

In co-operation with AMSAT-UK, the British Amateur Television Club will be operating a WebSDR for the narrowband segment, and a Spectrum Viewer for the wideband (DATV) segment.

Goonhilly Earth Station is supporting the project, providing hosting for the Ground Station facility at their world-famous site in Cornwall, UK.

Es’hail-2 / QO-100 Teleport Inauguration Day February 14

Es’hail-2 / QO-100 Teleport Inauguration Day February 14

At Es'hailSat Qatar - Credit AMSAT-DLFollowing the successful launch of Es’hail-2, the new Es’hailSat teleport will be inaugurated on February 14, 2019.

AMSAT-DL report:

This will also be the occasion to officially put the two amateur radio transponders of Qatar OSCAR-100, the first geostationary P4-A satellite from Qatar, into operation. The opening ceremony will be held 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 team of the P4-A team of AMSAT-DL, consisting of the 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 ground station of Es’hailSat. In addition to LEILA and the DVB-S2 DATV system, this also includes a club station for SSB radio operation under the callsign A71A. A backup station is installed at QARS in Doha. The ground station of the AMSAT-DL at the observatory Bochum is also ready for reception and transmission. 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 will the transponders be released for general radio operation by radio amateurs worldwide.

During commissioning, we expressly request that you refrain from any transmission attempts!

The SCC in Qatar, as well as Bochum in Germany, are carrying out some tests to measure both transponders and to calibrate the ground systems.

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

Es'hail-2 coverage areaEs’hail-2 coverage area

Furthermore, the rules of the game, as defined in the Operating Guidelines for the Narrowband transponder and Wideband transponder are formulated. Please observe the band boundaries of the NB transponder as defined by the upper and lower beacon! A later adaptation and possible extension upwards may be considered after first experiments.

Again: Please no uplink attempts until the official release of the transponders by QARS!

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

Help required in final tests before MarconISSta deinstalled

Help required in final tests before MarconISSta deinstalled

MarconISSta LogoThe International Space Station MarconISSta experiment will cease on February 9. Martin Buscher DJ1MBB asks radio amateurs with suitable equipment to participate in final tests.

The MarconISSta is a spectrum analyzer payload that monitors parts of the frequency spectrum in VHF, UHF, L and S band from the ISS in order to analyze current use and availability of bands for satellite communication.

Martin Buscher DJ1MBB writes:

We were just informed that it is likely that MarconISSta will be deinstalled on February 9, 2019. This is about three weeks earlier than expected, so we quickly have to finish any outstanding activities. Therefore: All Power To The ISS!

We want to invite everybody who owns a UHF antenna, preferably with an e.i.r.p. of more than 50 dBW, to do transmissions to the ISS. These transmissions will be recorded by MarconISSta and we will publish the results here. This experiment is a nice way for you to test your antennas, while it is great for us and ARISS to evaluate the ARISS VHF/UHF antenna pattern.

Transmission Details:
• Transmission time: Whenever you see the ISS between now and February 9th.
• Frequency: 435-438 MHz. Please avoid 435.95 MHz (our reference frequency) and 436.5 MHz (center frequency of receiver)
• Power: Continuous transmission of carrier, we recommend an e.i.r.p. of more than 50 dBW

Please do not use Doppler correction. We want to see the Doppler shift, it might help us to localize your transmission from this.

On November 15, 2018, Es’hail-2/P4A was launched on a Falcon 9 launch vehicle from the Cape Canaveral Air Force Station Space Launch Complex 40 in Florida.

Es’hail-2/P4A was developed jointly by QARS (Qatar Amateur Radio Society) and Es’hailSat (the Qatar Satellite Company), with AMSAT-DL as the technical lead, and is the first geostationary amateur radio payload. The satellite has reached its final position at 25.9 °E, and the narrow and wideband transponders were successfully tested on December 23rd. The transponders are expected to be opened for general use in February 2019.

At the request of AMSAT Deutschland e.V., QARS, and Es’hailSat, AMSAT hereby designates Es’hail-2/P4A as Qatar-OSCAR 100 (QO-100). May the 100th OSCAR satellite be the guide star to future amateur radio satellites and payloads to geostationary orbit and beyond.
