Es'hail QO-100 Geostationary SAT from our club station

 At October 23 we manage to make about 35 QSOs after the antenna installation at our club station SZ5RDS. The antenna is 2,4 meter diameter dish with prime focus and a dual feed antenna for 2,4 GHz and 10 GHz LNB. The power amplifier was an EDUP-AB300 8w (2,5w in real world) driven by two SPF-5189z preamps in cascade. The radio used was my ADALM PLUTO SDR with TCXO modification for stable RX-TX. Software for RX-TX was the very impressive DJ0ABR Linux Tranceiver v 1.70.

A big thanks to SV5AZP, SV5KJO, SV5SKE, SV5SKF as Satellite expirement team.

Hope to have soon a permanent installation and hear you via the satellite...!!!
