Operation
This version: initial speed 20 wpm. Could save last speed to initialize at next startup
On startup speed reported as Morse Paddles generate dits and dahs Control switch (push button) reports speed Control + dit paddle → decrease speed Control + dah paddle → increase speed Hear 2 dits for each 1 wpm + or - Xmtr not keyed for control operations
