ARLA/CLUSTER: Primeiro contacto no modo digital OPERA via satélite geoestacionário Es'hail-2 / QO 100

[João Costa > CT1FBF]

Digital mode OPERA used on Es'hail-2

*Luis EA5DOM* and *Iban EB3FRN* have successfully completed the first
contact using OPERA via the Es'hail-2 / QO-100 geostationary satellite

Graham G0NBD writes about the contact on Digital Radio groups.io:

Interesting test by EA5DOM and EB3FRN after the successful EME tests, 3 cm
and 24 GHz terrestial links over 200 miles plus range. The latest involves
the newly released geostationary satellite.

Spots showing for 23cm on the PSK Map and the OPERA data base are actually,
dual band spots via the new Es’hail-2 satellite

Luis reports excellent results using the op05 mode, probably the ideal
satellite beacon mode, -20 db sensitivity, virtually zero bandwidth, and
with 50% duty cycle, only 15 seconds of Carrier in the 30 second timeline,
easy on the power budget, and a data decode, ADIF listed for DX hunters.
