I found qrq a week or two ago, and while qrq is probably a very useful program for people who need to improve their skills with Morse telegraphy, it might be geared more towards those who have already mastered the basics.
If you’re a newbie, cwcp might be more to your liking. Here’s the Linux Mint version.
Much is the same between qrq and cwcp, but it’s also clear that their target audiences are different. cwcp has speed and volume controls, but also has controls for adjusting tone and other audio cues.
qrq seemed to focus on recognizing call signs and building proficiency and speed, while cwcp starts with letter and number groups, and works up through English words and into other categories. cwcp also lets you type in your own text, and will replay it as tones.
Like qrq, cwcp will need a little nudge with the alsa-oss package. I don’t see where that’s listed as a dependency in Debian, but I don’t know that oss is necessarily out of fashion, particularly among Debian fans.
In any case, if you’re not hearing anything, that might be the reason. cwcp is part of the unixcw package, so it might be that you get more “modern” sounds support by bringing in the qt rendition. Try it and tell me.
cwcp alone is not in Arch, but the unixcw suite is in AUR. If you only want the one program, it may be possible to carve it out. And if you’re an Arch user you probably can handle that. 😎
cwcp has color, as you can see, and I should note that cwcp seems comfortable arranging its layout to just about any terminal size, but only on startup. If you change dimensions after you begin your tutorial, cwcp might not notice it.
I think that’s about all I can think of to say about cwcp. It’s definitely every bit as fucntional as qrq, but intended more as a learning activity than as a speed and proficiency drill. Enjoy. 😉
