[TenTec] Omni VI excessive band-pass tuning authority?

[Peter Bertini]

I've noticed that the Band pass tuning range on my Omni VI and Paragon II
seems to be far larger than it needs to be--the actual useful tuning range
seems to be about 1/4 of the available control rotation.

Has anyone else noticed this?  Has anyone come up with a modification to
reduce the range?  I'm thinking of adding some end resistance on the pot.
