Question straight to Jeff:
Is it possible to use some kind of potentiometer for tuning, that has no limit - you can turn it around, and to select the station - you could use a push action, or it could be step potentiometer. I am not that much into electronics, as I am into open source, hence my question.
PS. The reason for that is I have like 20+ radiostations and the knob is getting very sensitive. Maybe I should change it to different one with other resistance?
