[Elecraft] KAT500 Remote software and KPA500 remote software

[Jack Brindle]

Let's see if we can determine why you are seeing this behavior. What platform are you using (Window, Mac, Linux), and exactly what is the scenario and conditions you are seeing? In other words, please provide more info. I believe K6KR has provided a bit of additional info. He wrote the KPA Utility for Windows, and knows the computer side of things.

I wrote the code for both the bootstrap loader and the main program in the KPA500. I tested all parts of the code operation for both bootstrap (which runs with front power off) and main firmware (runs with power ON) with both the Mac and Windows Utilities for each KPA500 firmware release as well as when the Utilities are released. In fact I tested it earlier today with both the original KPA500 and a newer one I bought a year ago. In all cases the KPA Utility was able to turn on and off the KPAs properly.

With adequate information, we should be able to get things working properly for you.

73,

The Utility does a great job of detecting the KPA500’s current data rate whether it is on or off (the two rates may be different) and will communicate at the proper rate to power the amplifier  on or off using the ON/OFF button in the Operate panel.
