The call sign OM0MS belongs to Slovak radio amateur Štefan Marcinčák, who works in the village of Topoľovka in the district of Humenné (locator KN08VW). Štefan, also known as Števo, is a recognized radio amateur, especially in the field of satellite communication. He is considered the first active Slovak radio amateur who established connections via a geostationary satellite QO-100 (Es’hail-2) . Števo je známy svojimi spojeniami cez QO-100 a experimentovaním s Moon-bounce (EME) technique. For EME experiments, experiments use a parabola with a septum feed according to the design and production of Rasťa OM6AA. We also decided to report on the successes of a few days ago, but you can find more at https://www.QRZ.com/db/OM0MS
