Hi Warren,

Cool article, peaked my interest enough to read on. Man that's low, probably lower than n3wwl's voice!

60 seconds per dot rate for CW.  Man, and I thought 5wpm was slow.

  Yes, a 60 second dot is equivalent to .02 wpm!  You don't receive by ear, you feed the receive audio into your computer soundcard. With appropriate software you look at a waterfall display and the cw appears graphically. 
   Below is my reception in Massachusetts  of Laurie Mayhead G3AQC in the U.K. this past February.  Laurie is sending "AQC" .-  --.-  -.-.  between  135.921 and 135.922 (frequency scale on the right  border of display).

I see that the screen capture may be hard to read so below is a close-up of my transatlantic reception of G3AQC "AQC" last Feb 27:
