\"Es'hail-2Es’hail 2 is a geostationary satellite which will carry two amateur radio transponders<\/a>.<\/p>\n

The launch of the Es\u2019Hail-2 satellite into a\u00a0geostationary 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.<\/p>\n

The two \u201cPhase 4\u201d 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.<\/p>\n
