About me


Who I am?

Started in 1995 with training in electronics and telecommunications, one year later I received my callsigns as amateur radio (YO7-021/VL) receiving only. The same year I passed the exam and become authorized to transmit using the callsign YO7GTM (EU novice / RO IV & III class). The coming years went through the different examination sessions and get authorized with the class I (HAREC / CEPT). Traveling around the world I held temporary callsigns: OD5, OE, CN2GMT.
