ARLA/CLUSTER: É possível efectuar contactos com 2,5 miliWats com o sistema OPERA no satélite geoestacionário Es'hail-2 / QO-100

2.5 milliwatt OPERA signal via Es'hail-2

*Markus Vester DF6NM* successfully used the digital mode OPERA to send a
2.5 milliwatt signal through the 2.4 to 10 GHz amateur radio transponder on
the Es'hail-2 / QO-100 geostationary satellite

*Graham G0NBD* writes about the contact on Digital Radio Groupsio.

On March 3, 2019, Markus started using 250 milliwatts of OPERA on 2.4 GHz
into a 60 cm dish pointing at Es'hail-2. The downlink signal was received
via the AMSAT-UK and BATC 10 GHz WebSDR at Goonhilly in Cornwall by *Peter
Knol PA1SDB*.

Markus then reduced power to just 2.5 milliwatts and the signal was still
receiveable.
