This is a demonstration of what I created with Node Red. I'm running a Flex 6400, Elecraft KPA500, KAT500 and all of this is connected to a Raspberry Pi 3B. The flow I developed also interfaces with ACLog and allows me to monitor POTA Spots and send that data to ACLog and SmartSDR. The flow also has a Power Guard to help adjust the power of the Flex as to not overdrive the KPA500.
