Occasionally when using my FLEX-6500 with my ACOM 600S I get the error "Detected RF Power At Wrong Time." The ACOM manual isn't much help nor is Google. Anybody else get this error? How did you fix it?
I figured it out. My tuner, a Palstar AT-AUTO, was preventing the amp from keying. It was doing this even though it had auto-tuned to a frequency I had used before. After I manually tuned the issue went away.
By the way, do either of you use buffers between the amp and your Flex?
