* Es'hail 2* is a geostationary satellite which will carry two amateur
radio transponders
The launch of the Esâ€ÖHail-2 satellite into a 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
10489.550 - 10489.800 MHz Downlink
Wideband digital transponder
2401.500 - 2409.500 MHz Uplink
10491.000 - 10499.000 MHz Downlink
This video describes the current progress (June 22, 2016) of the software
defined transponder with a CW and Phase-3 style standard beacon.
