Eshail 2 is a geostationary satellite which will carry two amateur radio
transponders.

The launch of the Es’Hail-2 satellite into aÂ*geostationary orbit is planned
for the 1st quarter of 2017. The coverage area of the Narrowband (NB) and
Wideband (WB) transponders should extend from Brazil to Thailand.

The two “Phase 4� amateur radio non-inverting transponders will operate in
the 2400 MHz and 10450 MHz bands. A 250 kHz bandwidth linear transponder is
intended for conventional analogue operations and an 8 MHz bandwidth
transponder for experimental digital modulation schemes and DVB amateur
television.
Narrowband Linear transponder
2400.050 - 2400.300 MHz Uplink Right Hand Circular Polarization
10489.550 - 10489.800 MHz Downlink Vertical Polarization

Wideband digital transponder
2401.500 - 2409.500 MHz Uplink Right Hand Circular Polarization
10491.000 - 10499.000 MHz Downlink Horizontal Polarization

This video describes the current progress (June 22, 2016) of the software
defined transponder with a CW and Phase-3 style standard beacon.
