About this app

Learn or improve Morse code with Morse Trainer. Now with Farnsworth speed and Koch method.

With a lot of settings it is very comfortable to adjust Morse Trainer to your current level.

The following settings are available:

- Frequency (200 - 2200Hz)
- Waveform (sine / triangle)
- Fading (to reduce click at the end of a dot or dash)
- Speed (2Wpm - 52Wpm)

- Letter Spacing (Space between letters)
- Word Spacing (Space between words)

Five different learning modes are available in Morse Trainer

- Random groups of X mode: Morse Trainer will play groups of X randomly selected letter, numbers or special characters. X can be an amount between 1-9. Those characters can be individually selected. If you want to learn just "s","i" and "e" just select the 3 letters and Morse Trainer will create groups of X with those 3 letters.
The characters can also be chosen from 20 lessons of the Koch method.

- Real ham radio callsign mode: Morse Trainer will randomly play real amateur radio callsign from a database of 5000 callsigns which appeared in Contests over the last couple of years.

Good, but trying to get to the screens where you set the characters or send speed settings etc is a bit glitchy, it doesn't always appear when want it to. The actual sending of morse is really good..very flexible what different characters you want to hear, speed and group length, it's just getting to the settings in the first place that is sometimes problematic. One star dropped because of the glitch.

This app is sufficient for beginning CW training. Sometimes the randomizing callsigns just don't make sense, sometimes the characters don't match the audio - especially so at slower speeds. So learning qso formats can be frustrating. It got me started but I think I'll be moving on.

I love this app. I'm now up to 30 WPM . I listen to news in Morse by copying text from news outlets. I've been using the "Farnsworth" method and lately switching to the "Wordsworth" technique by adding additional dot spacing between words. I have only one complaint/request... Please add an apostrophe (') to the character list. Thanks
