MFJ tuners that use switched tapped air inductors often fail to allow sufficient spacing between each tap and the adjacent turns of the coil, and either heat expansion or high-voltage arcing can cause shorts between the tap and an adjacent turn, completely changing the effective tuner settings, as a result. On MFJ's "Mobile" tuner I had to bend the adjacent turns away from the soldered taps (by pushing each adjacent quarter turn into the coil's interior, which is standard practice for these air inductors) in order to get it to work right.
