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.
