Perhaps that's so Bob. But, I was one of those contesters (frankly it was
a boring contest; condx. were lame - especially for doing it QRP like I did
it). There still are a fair amount of us who do like me - copy by ear. I
also sent by hand with a single lever paddle (20 years of Bug use screwed me
up for double lever paddles, LOL). Some of the stations like PP5T, and
6Y1LZ were running about 35-40 WPM. I worked 'em both. All of the high
speed CW I did in contesting, helped me to pass the 20 WPM my Extra
required, when I took it back in 1994.
