Lots of people are building their own with a microcontroller and some kind of rotary encoder. One super easy way is to use the teensy arudino clone (or similar) since they already have libraries for USB HID so you can make your scroll wheel act like a mouse scroll wheel.
Rotary encoders exist in many different qualities. Optical rotary encoders are really nice, and expensive. I've also seen people using stepper motors as encoders. --Albin On Mon, Dec 28, 2015 at 12:33 PM, Daniel Pocock <[email protected]> wrote: > > I realize that SDR provides more than one way to view the spectrum and > tune to a frequency, but I can imagine some people feeling comfortable > with a tuning knob similar to a traditional radio.
