After many years of being inactive, I want to get back into amateur radio and
brush up my *VERY* rusty Morse.
Can anyone recommend a good Morse training program which uses the sound card,
please? I want to listen to it with headphones. Preferably one which also has
a GUI rather than just using the command line, but I am not all that fussy
This Koch system sounds rather interesting.
I could spend hours Googling and downloading several to try, but a
recommendation would be better.
Very many thanks
