Es'hail 2
Es'hail 2 (a.k.a. Qatar-OSCAR 100 or QO-100) 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 operates 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 features 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 500 kHz and 8 MHz for the amateur radio satellite service, with uplink on 2.4 GHz (13-cm band) and downlink on 10.45 GHz (3-cm 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” (LEIstungs Limit Anzeige, English: power level indicator) siren. When they have been marked by “LEILA”, operators should immediately reduce their uplink power (ERP).
No FM transmissions should be made to Es’hail-2 as these would use excessive power and bandwidth.
Linear Transponder for Digital Amateur Television (DATV) and other highspeed data transmissions. First DATV transponder in space.
All uplink transmissions should use the minimum power possible. QPSK transmissions should have a downlink signal with at least 1 dB lower power density than the Beacon – the web-based spectrum monitor enables users to set their uplink power to achieve this. Transmissions with symbol rates of less than 333 kS using 8PSK, 16 APSK or 32 APSK should use the minimum power density required to achieve successful reception.
