[Elecraft] KPA500 STBY to OPER

[Andy Durbin]

"The issue is timing. Your code has to poll to determine the KPA op state, then start all the transitions which will result in the PTT line being negated."

No, not true.  There is no timing issue with my implementation since the key line is ALWAYS inhibited while KPA500 is in STBY mode.   Required conditions have to be met before the key line is enabled.  Any delay due to my slow system interfaces simply means that it takes a bit longer for the KPA500 to be set to OPER power level.

Thanks for the explanation of the KPA500 K3 power control interface.

The driver for  doing a write up of my controller will probably be my club's presentations manager.  He has twisted my arm a few times to prepare and give presentations and I'm probably due for another turn in the barrel.
