From 
From January 1 to December 31, 2004, the station will broadcast on the amateur bands with the occasional tag OM100TS. It is a brand assigned to the radio club of Jozef Murgaš OM3KJF on the occasion of the 100th anniversary of the granting of the patent for the Tón system. How will it be with QSL lístkami zatiaľ neviem, nezohnali sme sponzorov, ale budem na nich aktívne pracovať. Info o pridelení značky som sa dozvedel 30. 12. 2003 o 10:30. Prosím o zverejnenie info na CQ.SK.
YOU 73 Miro
TNX for the info Miro, good luck!
