I’m a ham radio operator with the callsign K5OHY. I enjoy experimenting with antennas, chasing contacts, and operating CW (Morse code). Most of my videos are about portable operating, antenna experiments, and sharing some of my adventures. Every now and then I’ll post some guitar playing. 73 de K5OHY
