[CW] Sounds of the Code

I've loaded some sound files for giving examples of different keys sending 
Morse code.

Bug sending (recorded by W1YT around 1982)

Cootie key demonstration:

Fast Straight Key sending:

The bug and cootie sending are mine.  The bug recording is about 25 years 
old.

When I first learned (?) to send on a sideswiper (or cootie key), I finally 
made a recording when my "attempts" to send the alphabet and numbers finally 
was able to be done without error.

The fast straight key was from a circa 1915 recording on a recording disk 
made to teach radiotelegraphy that I found on the web.  I had thought the 
speed was near 25 wpm, but Gary Bold, ZL1AN and others measured the dots 
(time in milliseconds) and found it to be around 23 wpm.

I hope these recordings bring a smile to your lips.
