I once asked about this on the Ten Tec reflector during a discussion of high speed CW, but some of the high-speed guys there assured me that they routinely copied 100 wpm without apparently being bothered by filter effects. I had a hard time believing this. They must use pretty wide filters to avoid the ringing or group delay effects that you mention, Bill. But they really didn't tell me for sure. > Here's my question - what person can copy 100 wpm? Only a handful of > people in the world can copy 60 wpm! > You and I think alike... this was my exact next question to the guys. But again, they just sort of shrugged me off and never indicated that they thought they were pushing any limit of human ability. In fact, one guy told me that there is an entire group of folks who gets together on 40 meters at 100+ wpm! Around 7032 if I remember correctly. I've never heard them. At this speed Ted McElroy's world record, set back in the 1930s, should be threatened, but I don't know what is up with that. I believe-- though I am not sure-- that actually writing down (or typing) what you copy is really difficult at that speed. In other words, it is actually easier to simply copy in the head. McElroy's greatest achievement was evidently being able to produce a hard copy of what he heard.
