It was in last century.

My friend and one off my  Amateur Radio Mentor : 9A2UX Vlatko, started with RS ( Radio Sputnik ) program in Radio Club “Slavonski Brod” 9A1CRS ( in that time callsign was yu2CRS ).

Wee got hundreds of paper sheets with next days prediced orbyts for  RS OSCAR Satellite .

And made many QSOs ,even some Transatlantic QSOs…

After many years I started again AMSAT operations.
