Welcome to SparkGap Labs!

We're a tiny (one person, really) business located in Massachusetts, USA. I'm also a fairly new, licensed ham radio enthusiast. After initially becoming familiar with SSB and digital modes, I wanted to learn Morse code too. After a while of using readily available web-based tools and some smartphone apps with limited success, I thought a dedicated stand-alone device that would let me practice sending Morse code as well as just learning to copy/receive Morse code would be better. Web-based apps didn't really allow that, nor did any app I could find.

Being a long-time computer programmer with a hobbyist knowledge of microcontrollers and electronics, I had an idea for a purpose-built device to learn Morse code. After a few design iterations (including a small stack of incrementally improved PCBs), I arrived at a design which I liked. Comparing it to other devices available, I thought it would be fun to turn it into a project that could be built by others as well. This ended up being the product you see being offered here, the MCT-73 Morse Code Trainer.

I've had a blast designing and using it. If you're looking to learn Morse code, you might be interested in getting a MCT-73 Morse Code Trainer of your own. It's mainly sold as a kit (intermediate soldering skills and some simple tools required), but I also periodically hand-build and offer completely assembled and tested units.

Thanks for your interest, and good luck learning Morse code!
