As a 20wpm Extra of advancing age, I admit I can no longer copy at 35. In fact, I will also admit that now days I begin to have trouble at around 20.
I’m not a contester, but what I’ve taken to doing is haunting the Novice bands. I answer CQ’s about 2 to 3wpm faster than they’re being sent. I do it to honor the Extras/Advanced/Generals that “Elmered” me some 55 years ago.
Try it! It’s a lot of fun.
Yeah, I know ... kinda off-topic! But this website is about building things! We can also build the next generation of CW operators.
