Using the CW keyer as a morse practice oscillator

A member of the BITX20 list asks, “How can I use the keyer in my µBITX for CW exercises with a paddle?

The answers include:

1.  Remove the power to the finals (this is the centre pin of the power connector)
2. Use the KD8CEC software, which has a menu setting to turn off TX
3. Modify the supplied manufacturer’s software to disable  TX
