Gary, in my case the fluctuating SWR indication turned out to be attributable to my station ground setup. It seems that just a small amount of RF on the feedline can create this symptom. My non-resonant antenna comes into a balun, then the coax goes through a line isolator, and thence to the rig. There is a counterpoise arrangement connected at the balun which has served satisfactorily to ground everything with a couple of antennas. However, when I put up a new one, I got the symptom you describe. Some tweaking of the grounding scheme completely cured it.
