Es'HailSat-2 will carry two geostationary “Phase 4” amateur radio
transponders !!

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.
