Re: Es'HailSat-2 will carry two geostationary "Phase 4" amateur radio transponders !!
I agree with you Stefan. At 26 degrees east, the satellite should cover all of Europe and Africa. Coverage may stretch west to Iceland, eastern Greenland, and the eastern tip of Brazil. Coverage should stretch to the east to most of India, and western halves of China and Russia.
It won't reach to North America, South America (except eastern edge of Brazil), Australia, or Japan.
Nonetheless, it sounds like a great project, an excellent opportunity to gain experience with a GEO platform, and a demonstration of technical competence.
Best wishes and hopes for success to the Qatar Amateur Radio Society and AMSAT-DL!

That is indeed a great project!
Now, if the satellite is positioned at 26 degrees east it will not be useful for North America. Is that correct? Preliminary footprint analysis shows it just touches the east side of Brazil.
Thoughts and comments appreciated.

As a result of a concept proposed by the Qatar Amateur Radio Society, Es' Hailsat, the Qatar Satellite Company, have announced that their new, geostationary, Es'HailSat-2 communications spacecraft will provide transponders for use by radio amateurs. The spacecraft is expected to be ready for launch by the end of 2016. Es'HailSat-2 will provide a 250kHz linear transponder intended for conventional analogue operations in addition to another transponder which will have an 8MHz bandwidth. The latter transponder is intended for experimental digital modulation schemes and DVB amateur television.
Precise uplink and downlink frequencies remain to be finalized but the uplinks will be in the 2.40-2.45GHz and the downlinks in the 10.450-10.500GHz amateur satellite service allocations Both transponders will have broad beam antennas to provide full coverage over about 1/3rd of the earth's surface. Precise operational plans will be finalised over the coming months but it is anticipated that only quite simple ground equipment will be required to use this satellite.
A team of amateurs, led by Peter Guelzow DB2OS (President of AMSAT-DL) are providing technical support to this ground breaking project which is expected to provide an exciting new phase of activity for radio amateurs for the 21st century.
