Es'hail 2


Es'hail 2 is a Qatari satellite, launched aboard a SpaceX Falcon 9 rocket on November 15, 2018. Es'hail 2 was built by Japan's Mitsubishi Electric company, and will operate at 26° East longitude along a geostationary orbit to provide direct-to-home television services in the Middle East and North Africa region.
The satellite will feature 24 Ku-band and 11 Ka-band transponders to provide direct broadcasting services for television, government and commercial content distribution. In addition to commercial services, the payload of Es'hail 2 includes a linear transponder with a bandwidth of 250 kHz and 8MHz for the amateur radio satellite service, with uplink on 2.4 GHz and downlink on 10.45 GHz.

Amateur radio transponders

"NB" Transponder (narrow band)

Linear Transponder for low power narrow bandwidth voice, morse and digital communication
The narrowband transponder is intended for conventional analogue and narrowband digital signals.
No transmissions should be made beyond the nominal edges of the transponder passbands. In particular, no operation should take place below the lower beacon nor above the upper beacon.
No uplinks should result in downlink signals that are stronger than these beacons. In the event that such signals are detected, they will be marked by a “LEILA” siren. When they have been marked by “LEILA”, operators should immediately reduce their uplink power.
No FM transmissions should be made to Es’hail-2 as these would use excessive power and bandwidth.
Although there is no formal bandplan, the following details are provided for initial guidance.

"WB" Transponder (wide band)

Linear Transponder for Digital Amateur Television and other highspeed data transmissions. First DATV transponder in space.
Well over 130+ amateur radio operators have used the amateur radio transponder in the first few weeks of operation.
