<div>At least some of the encoders on ham equipment are optical encoders. I repaired one within the last year. (The knob has the requisite <span id="m_9217598937679310532m_-7256985319649968191:1bu.1">fingertip indentation.) Being optical in nature, control can be almost anything you'd want. I would guess that the resolution was maybe 120 PPR or better. The specific unit was a Yaesu FRG-100 general coverage receiver and the optical encoder was the main tuning dial. If these could be obtained inexpensively, they would be wonderful for synth control. It has been a while since I looked but think that even these "cheapie" encoders are still in the $30 - $40 range (or more).<span class="m_9217598937679310532HOEnZb"><span style="color:#888888"><br><br></span></span></span></div>

<div>That reminded me of something else with built-in "switching" between coarse and fine control:<br> Those encoder knobs on many HAM radio transceivers to tune, with a dent near the outer radius, where you can rest your fingertip and use the thing as a crank with very quick rotations, or grab the whole thing for fine control.<br> Needs more space of course, for those things are bigger than the average knob on a synth module. And the encoder has more wear if the solution is "turn it more!", if it's a mechanical one. And I'd guess things finger tip cranking doesn't feel nice with some encoders hard detent.<br> Something like this:<br> <a href="https://www.adafruit.com/product/2055https://www.adafruit.com/product/2055" target="_blank">https://www.adafruit.com/produ<wbr>ct/2055https://www.adafruit.co<wbr>m/product/2055</a><br> </div>
