Es'Hail-2 geostationary satellite (credit: Es'hailSat)
The main purpose of the new geostationary satellite Es'Hail-2 is to provide television services to the Middle East and North Africa. In addition to commercial services, Es'hail 2 includes two linear transponders for amateur radio; one with a bandwidth of 250 kHz and another one with 8 MHz. The uplink for both transponders is 2.4 GHz; and downlink is on 10.45 GHz.
Es'Hail-2 Narrowband Linear transponder:
- 2400.050 - 2400.300 MHz Uplink
- 10489.550 - 10489.800 MHz Downlink
The footprint of Es'Hail-2 covers half of the world. That huge pattern offers new opportunities for many hams: DX can now be worked without erecting big HF-antennas. A satellite dish on the balcony is all you need.
My RX set-up is shown below. It is simple and cheap while still providing a taste of satellite DX. The Win 10 computer runs SDR#
The satellite dish is Triax TD78 (offset, 70 cm wide, 78 cm high). The LNB is Maximum ST-11 (single port) with PLL and 25 MHz crystal oscillator.
