I'd like to see a data box I can paste text into and have your cw engine play them back.
I think your site is spectacular for improving ones code speed from 5 WPM up to any speed, once you know the code. there are lots of sites for teaching the basic code, but not much in the way for speed improvement. W1AW is not much good for improvement, btw.
In an effort to improve my cw speed, I have created a series of data files including various lengths of random numbers, 1000 of the most often used words in the english language, radio terms, weather terms, male first names, Ham manufacturers, etc. I have to paste the files into a cw program, which is clumsy at best.
I'd like to see a box that I could paste my text files into and have your cw engine play them back to me with the parameters that I put into your engine.
I'd be happy to share my text files so that you could expand your playback repertoir.
