uP-controlled ones, yes; earlier analog-ones, uh-uh ;o(((((

The tuning rate is only a part of it; what bothers me is how my fingers,
after a few hours gripping that tiny knob, appear to become molded around
the teeny-dinky thing (and I almost have to pry them loose with the other
hand). And the joints become stiff ;o( So a large knob helps alleviate
that, in addition to allowing you to shift your fingers around a bit and
still control the knob adequately.
When it comes to evaluating the ergonomics of radios under design, I think
the manufacturers should be hiring Sumo wrestlers to test proposed panel
controls and layouts; if THEY can fit their paws on the controls, then the
controls are likely to be large enough for the rest of us 8-))))))
