CHANGING KEYING SPEED
The keying speed of the electronic keyer is fully
adjustable. Selecting the appropriate speed is
important in order to send error-free CW that other
operators can copy solidly. Selecting a speed that is
beyond your keying ability will only result in mistakes.
You will obtain the best results by selecting a speed
that is close to the speed used by the other station.
