Morse timing within a message is configured in the

Speed Racer lets you try copying at a higher speed than you are used to, and then gradually reduces the speed to a more comfortable one. Or you can start at a slower speed and gradually increase it.

You can choose to vary the character speed, Farnsworth speed, or both:

The table below shows the percentage speed change along with the character and Farnsworth speeds for each time the message will be played.

You can adjust the number of times the message is repeated (2 to 5), the maximum percentage change (-99% to +100%), and your base character and Farnsworth speeds:

Message speeds
Repeat	Percentage Change	Character Speed	Farnsworth Speed
	%



1	None

The Farnsworth Speed cannot go above the Character Speed: where the modified Farnsworth Speed has been limited by the Character Speed, it is shown in red.

Your advanced timing settings in mean that there is no simple Character Speed and/or Farnsworth Speed. The boosted speeds will use precise Character/Farnsworth speeds and the final play will use your custom settings.

QSO Notes

The semi-random sentences created do have a few limitations at the moment. There is not much variety in names and places or control over the QSO content. However, I hope it will already be useful and these things will be improved soon.

General Notes

There are many which can also access additional functions. Press ? to list them.

General help on the playback controls and Morse Controls (Timing) can be found in a separate page.
