I noticed that the Yaesu website shows a tuning knob for the FT-950 that has a sub-tuning ring incorporated into it. I searched for "FT-950 tuning knob" and it brought up information on the FT-950 Dial Kit. It says it will provide a great new tuning feel. The parts list shows a Sub Tuning Knob as well as a Main Tuning Knob. From what I can read, I WANT ONE!. Does anyone have experience with this knob mod? Where do I get one and what does the kit cost? Help.
