Save Audio saves the current message as an audio file.

Message Modifier - modify the message in different ways

Speed Racer boosts the initial speed by 50% and then repeats the message, stepping down the speed to your chosen values. Morse Repeat will play at the boosted speed if selected. Use the Speed Racer Controls to configure (see help).

Toggle the buttons to choose what sequence to play and show for each message:

Toggle the buttons to choose what sequence to play and show for each message; configure Morse, speech and bell:

Bell Gap (ms)

Morse timing within a message is configured in the Morse Controls

Speed Racer Controls

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.

The table shows the percentage boost and the message speeds for each message play.

Toggle the Speed Racer on and off and use Count to choose how many times the message will play.

Use the Boost Speed buttons to choose whether to boost the Character Speed and/or the Farnsworth ("effective") Speed.

Adjust your base speeds in the final row.

Message speeds
Count	Boost	Character Speed	Farnsworth Speed

5
4
3
2
1	None

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

Your advanced timing settings in Morse Controls 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 keyboard shortcuts 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.
