About Chris / N0CSW
I've been involved in amateur radio for over 20 years, and my professional background spans 27+ years in electronics, software development, and AI, which naturally complements the experimental nature of ham radio.
I worked at Yaesu USA for several years, I led the System Fusion project and helped seed more than 4,000 digital repeaters across the hobby to various clubs across the Unied States, Canada and Mexico. That work connected thousands of operators and expanded digital voice capabilities in the amateur radio community.
These days, I'm mainly active on digital modes across HF, VHF, and UHF bands. Feel free to reach out if you want to connect!.
Amateur Radio Projects
I occasionally work on a hobby project related to Amateur Radio. Here you'll find utilities, and experiments, some make sense while others don't. Feel free to reach out if you have an idea.
Koch Method Morse Code Trainer
This Koch Method trainer runs in your browser and teaches you Morse code the right way from the start. You hear characters at full speed (20 WPM) instead of slow, exaggerated beeps that create bad habits. Start with just two letters, master them at 90% accuracy, then add one more. Your progress saves automatically, and you can pick up where you left off on any device using a simple URL.
What is the Koch method? The Koch method starts you at full character speed (20 WPM) but spaces them out so you can process what you hear. As you improve, the spacing shrinks until you're copying solid 20 WPM code, no speed ramp needed.
WWII Enigma Machine Simulator
I saw my first enigma at the Friedrichshafen hamfest back in 2012 where I had the chance to get a real life demonstration from the good folks at the Enigma Museum, I was fascinated at first sight. This interactive simulator brings history to life with authentic rotor configurations, plugboard settings, and encryption algorithms. Discover how radio intelligence and codebreaking shaped modern communications security.
A turning point in history: Alan Turing and the codebreakers at Bletchley Park cracked the "unbreakable" Enigma cipher, intercepting encrypted radio communications and shortening the war by an estimated 2-4 years. Their work laid the foundation for modern computing and cryptography.
