I have pretty much the same symptoms reported by the KPA1500 users here. The higher the frequency the more likely to see a fault. 10M is the worst one. The amp shows a 2:1 SWR and that is running it into a tuned KAT500, which shows 1.2:1 and a Daiwa bridge showing 1.1:1 into the antenna. It's the same on a dummy load.
I don't understand Bob McGraw's logic as if it does require power, my Daiwa is gonna see it. If I measure the feedline, lightning protection and antenna with a network analyzer I will be doing it with mili Watts.
