[Elecraft] KAT500 auto trainer

[Andy Durbin]

"Extremely easy to do manually and stable."

It is only because my 160 and 80 m OCFD is being modified frequently that I decided to develop the auto trainer.   It takes multiple actions to tune a single bin and there are 20 bins for 160 m.   If a multi-step task needs to be done infrequently the effort required to automate it is not justified.  Do that task several times a week and the effort is easily justified.

Actions to auto tune at current frequency:

  1.  Inhibit the key line and wait for confirmation of inhibit
  2.  Initiate KAT500 auto tune (FT;)
  3.  Set Kenwood to TX Tune and set auto tune power
  4.  Wait for KAT500 FT response which indicates tune is complete
  5.  Set Kenwood TX Tune power back to 5 w then command RX
  6.  Wait for confirmation that TX has stopped
  7.  Enable the key line

Since that sequence had already been assigned to a single button push it was not too difficult to repeat it for each bin in the current band.
