I’m afraid the reply you would get would be Duh.
Not many people know Morse today.
And if you wanted to talk to me you would have to use a flashing light:)
Know morse well, but not wig-wag.
One thing about few people knowing morse is that gives some obscurity to the mode. It can be machine decoded if the fist is good, but human ears and hand on the keyer varries.
In the worst conditions, the presence or absense of a signal will go through when all else fails. Especially on low power.
There are still many good CW ops. Most not in US. Russians have many, you would expect that. Most really good CW ops in the US were X-mil. I knew one in OK that could do 60-70 WPM in his head. But he ran a mil for years copying 5 letter code groups. Made it automatic. (he is gone now, silent key)
On a serious note, off topic, if you have any hearing at all, get your chart from your last hearing test and get a DSP filter that you can set to match your hearing cut-off or notch frequencies.
I'm H3 as far as the federal gooberment is concerned, and I really don't hear (or listen) well. But with a good DSP filter (I use a Timewave(tm)), I can pick out morse without a problem.
