I opened mine up and looked at L5 and L6 one of them is just a plain old coil of wire, no way to adjust it. The other one I adjusted. Took me about 30 minutes since I used an SWR meter, and retested the SWR after each little tweak and retested it. The needle is as high as it will go when I key up now. If I move the adjustment in either direction I get lower readings, accross everything. My antenna is also spot on to the radio in the channels I frequent most(17 and 20). Hopefully I did it right. I also clipped my mod limiter. I have a ham radio linear that works with it quite nicely when it's set on the 10 meter band. The bad part is I can't use it when mobile(the linear) as my inverter won't push enough power to run it(only a 150 watt inverter), so it doesn't really get used. I need to find my other radio which has an 858 chip in it as well as a "channel kit" and get it finished up and use it. It's a pretty badass little rig. When I find it I'll post up on it what model it is and all that.
