Re: rotary encoder

 

It is possible to test the mechanical switch type rotary encoders by using a pair of resistors and
LEDs to show the outputs as the knob is turned slowly.? Connect a 1500 ohm resistor from +5
to the LED and the LED cathode to an encoder output.? If you use two resistors and two LEDs
you can see the quadrature output states.?

A friend thinks he has a problem with the rotary encoder in his uBITX.
Does anyone have the part number for it?
