Koch Trainer is a morse code trainer that uses the Koch Method developed by the German psychologist Ludwig Koch in the 1930's. The method basically states that you should learn morse code at the speed you expect to receive, by training your reflexes to respond to code sent at 20 WPM you'll learn the code much faster.

Handy trainer

…locked up on me once (I think the program was encouraging me to take a break) but after closing/reopening have not had a problem. I run it on Mac Mini OSX 10.9.5 Don’t use the scratch pad feature (just paper and pencil for now) but the improvement suggested by SchaqFu would make this program even better. Really like this resource and it’s improving my CW skills copying and sending…thanks and 73!

Not on the iMac

I installed on my iMac and began to develop an ear in lesson 1, but then the app stopped functioning. When I pressed play there is no sound. Upon visiting User Support the note is to turn off mute, but my sound is on. The app works fine on my iPad so far. I want it to work on my iMac. I will rate it Don’t Like It for this reason.

Spat sound instead of a dit

Dah’s are okay, but the dots sound like splat, kind of like the noise you get when plugging in head phones or a speaker into an active amplifier, it isn’t very clear. Sometimes the spats obscure the next dits
