These are from the days of the old "click-mode" of Morse. A click and then a
short Period until the the next period. This was a rather confusin method of
Morse. Thank God for more intelligent ways to communicate. Ways that are
conducive to our fast pasted life-styles.

I have used morse code with a key (ve3gqx) but have always wondered how
people sent and recieved code by tapping on pipes etc.
Can anyone explain how this is done? How does one distinguish between a
dot and a dash?

tnx
