Before I go looking too hard, is there a macOS app for the KPA500 or *just* the Windows app on the Elecraft site. If it matters, I’m looking to interface the KPA500/KAT500 combo to a Flex 6400… Maybe. I’ve not bought the amp or tuner… Yet. My preferred OS is macOS but I do use Win11 in a VM for Winlink using my Flex. Thanks, Joel - W4JBB
