TK20 Practice Key with Oscillator & Full Tutor!

Avaiable as a Fully Built item or as a Full Kit  BUILD INSTRUCTIONS

This is a combined  Morse Practice Key with an built in Morse tutor too. 

This CW Training key is designed to serve two purposes, the first is to act as a practice key to improve your sending. The second is to also act as a Morse tutor too.

Bespoke software allows a lot of functionality. With just two knobs and the key you can change the tutors WPM rate, the oscillators pitch, the gap between characters and of course the volume to the built in sounder.

The batteries are mounted at the rear of the key making it completely self-contained.

The key is a nice little low cost project that would be ideal for clubs running the novice train course or any buildathons. It needs both soldering and mechanical construction to finish the kit but should be well within the scope of any one that knows which end of the soldering iron to hold.

The key uses a small but powerful micro controller loaded with my own bespoke software. I don’t believe that I have seen anything like this before.

The Tutor mode as 5 different modes, all random.

Random Letters
Random Numbers
Random Prosigns
Mixed mode
International Callsigns (In this mode the Pitch and speed will change by upto 15% to make this more challenging
