Tony Breathnach, EI5EM
Ham Radio YouTube Channel
This is my amateur radio video channel. My name is Tony Breathnach from Dublin in Ireland. My callsign is EI5EM. I am interested in building my own radio equipment and operating using Morse Code especially QRP portable. I like experimenting and sharing my knowledge. I particularly like operating QRP (low power) equipment especially outdoors. Best 73 es 72 de Tony (EI5EM).
