The geostationary satellite Es’hail-2 carrying amateur radio transponders launched from Kennedy Space Center at 20:46 GMT on Thursday, November 15, 2018 and is now in a geostationary orbit at 25.9° East. These are the first amateur radio transponders to be put into geostationary orbit and they are expected to link radio amateurs from Brazil to Thailand.

Es'hail-2 coverage areaEs’hail-2 carries two “Phase 4” amateur radio transponders operating in the 2400 MHz and 10450 MHz bands. A 250 kHz bandwidth linear transponder 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
