Default LATE MODEL MFJ ROLLER INDUCTOR IS ROUGH

Hi All,

I have a couple of late model MFJ roller inductor antenna tuners with the
roller on the inside of the inductor. My old 989C with an external roller was
smooth as glass. These newer ones with the roller on the inside of the inductor
really are rough. They have a knob with a finger hole, but cannot be spun with 1
finger--you have to grab the entire knob to turn it. I have a 989D with a crank
type knob that has a slip clutch as part of the knob, and if you try and turn it
real slow, the clutch slips instead od the roller progressing slowly.

Has anyone "fixed" this problem with their late model MFJ ???

I fixed mine by just returning the 989D to AES -- they took it back.
My old circa 1992 989C is a marvel of precision, in comparison :-)
