Es'hail 2 / QO-100 is a geostationary satellite carrying amateur radio transponders that was launched in November 2018. It provides the first amateur radio communication capability from Brazil to Thailand using two transponders - a 250 kHz linear transponder for conventional analogue operations and an 8 MHz transponder primarily for DVB amateur television. The presentation discusses receiving signals from the satellite using various hardware and software, as well as transmitting to it. It also includes a quiz about the satellite.

4. About Es'hail 2
• The geostationary satellite Es’hail-2(Oscar 100) 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.
• Es'hail-2 will provide the first Amateur Radio geostationary
communication capability from Brazil to Thailand. It will carry
two AMSAT P4A (Phase 4A) Amateur Radio transponders. The
payload will consist of a 250 kHz linear transponder intended for
conventional analogue operations in addition to another
transponder which will have an 8 MHz bandwidth(primarily for DVB
amateur television).The uplinks will be in the 2.400-2.450 GHz(S
Band) and the downlinks in the 10.450-10.500 GHz(Ku Band)
amateur satellite service allocations.

18. Why all DVB-S2 receivers are not suitable for
Es'hail 2 beacon Reception?
• Tuner hardware does not support reception
below 950 MHz
• Even Hardware support Software prevents
• Some receiver support blind scan below 950 MHz
• Some tuner (Like Serit) support 250-2150 MHz,
MiniTouner is based on this tuner
