Electrical Engineer · Licensed Amateur Radio Operator (Extra Class) · 25+ Years Experience

My grandfather taught me to tap out my first SOS when I was eight and I have been interested by morse code ever since. I earned my amateur radio licence in 1998 and had fun making CW (continuous wave) contacts with operators on six continents for 20 years. I have a strong background in signal theory from my electrical engineering training at MIT, but it’s the personal tales behind the art of morse code that continue to fuel my love for maintaining this skill. I made this resource because I found too many online morse code translators to be clunky, inaccurate, or filled with adverts that get in the way of meaningful practice. All of the tools and guides here are tested on genuine radio bands and have been refined via input from the amateur radio community.
