The Hamcrafters K16 Memory Keyer is a tiny little board with a handful of parts that does an amazing job. Being both a memory keyer with 4 programmed memory slots so you never have to key CQ again 🙂 and an Iambic keyer. As you can see in the photos the board is tiny, only 5cm long, and can be used as a practice oscillator with its own piezo speaker.
