It makes me wonder why Drake chose to use an electromechanical encoder

Lowe HF-150 (which if my memory serves was manufactured during
approximately the same period) uses one, and I'm reasonably certain it
sold at a lower price point than the Drake.

The Icom R75 uses optical encoders too. Works fine.



My SW-2 had a mechanical encoder, too. It got so flaky, I started
looking for options. Peter G. posted a mod for converting Drake
mechanical encoders to an optical encoder. I was about to go that
way before someone posted a procedure for cleaning and relubricating
the mechanical model that would eliminate the current problem and
forestall future issues. I opted for the cleaning, and never had
another problem for the remainder of the time I owned the radio.

I'll try to dig up that remedy.
