The Morserino is a Morse code (CW) trainer. It comes with paddles for training. You can plug in your own straight key or your own paddles. It teaches you cw (morse code) interactively. It has Lora (unlicensed radio frequency) so you can have one Morserino talk to another Morserino if you want to have one person in one room and the training buddy in another room. It connects to the Internet. And it acts as a keyer for radios that do not have a built-in keyer (like most HTs. Technicians can us CW but generally are not equipped for it).
My Morserino arrives at the end of May and I’m absolutely giddy over it. I began this journey in 1980.
