Hi All:
The encoders work fine with mi suggestion, however this solution resoults partial. I explain:
The encoder accuracy in VOR and ADF gauges is not very thin and jumps, its fast but not accurate. It's a bit hard to pick a exact value because encoder operation.
I am trying another option in search of better accuracy while maintaining speed with the ALPS EC 11 encoder. This encoder is a rotary unit, like CTS encoders, but the difference is in the operation. ALPS encoder has only 3 position (like a selector) ON (pulse) - NONE -ON (pulse). You may operate the encoder with one movement to left or right to obtein the pulses. and when you release de knob, the encoder self-return to NONE position in the center. The encoder turnrs like a CTS encoder but not complety, its a single turn to left or right. Visit this link for more info of EC11 encoder http://www.alps.com/WebObjects/catal.../EC11/EC11.PDF
Good luck
