Hi, I bought this rig secondhand in May and I'm reasonably happy with it. Two things, however: Intermittently I lose output from the SUB using Dual/Split. Only one band fails at any time? But i have seen it on 30, 17 and 12 at least. I've also heard the APF should be so good, but find it very much better on my IC-756. Adjustsments? Any info/help appreciated! 73, Hans LA9HF
