I still am rather annoyed at Drake for putting such a
lousy encoder on the R8B. For that kind of money, I'd
expect something with a lot better longevity and feel. I'd
have gladly paid an extra $50 for the radio for the
"optical" option, if Drake had offered it. I bet a lot of
you would too, given how much better they work.

Drake did use an optical encoder in the original R8. They stopped using
it because, according to them, it had problems. I've found that
disassembling the rotary encoder, cleaning it with DeOxIt and relubing
it with a synthetic grease like 'Superlube' has solved the intermittent
problems that occur with age. Perhaps the factory lubricant doesn't
react well with the encoder contacts.
