Hi gang. I found a great idea for tuning of SDR radio using a cheap mouse and rotary encoder on www.cq.sk http://www.cq.sk/img/sdr_rotacny_enkoder.jpg
Just buy a cheap mouse (Genius NetScroll 1200 on picture) and replace the whell optical encoder with a panel mount rotary encoder with knob. It is certainly a cheaper solution than to buy a dedicated knob product. 73, Vojtech OK1IAK, AB2ZA
