Lots of folks have, want to or still operate CW on HF Frequencies. Many of us spend lots of time attempting to learn CW, both sending and receiving. When we’ve “gotten it” we’ll work to improve our “copying” speed and listen to HF bands hearing folks so fast we believe we’ll never understand what that guy is sending! Even some experienced operators don’t quite copy like they used to, lets look at some options for all of the above, our computers can give us a little help both receiving and sending. I have not tested most of these and I know many are “Trial” versions of paid software, some are public domain (freeware) you will have to evaluate each for its usability and whether it is worthy of your hard earned cash.
