DCS bios and encoder debouce

[Gareth Barry]

Hi there

I'm having issues with the rotary encoders that I am wanting to use for Tacan and radio channel select. They are the simple type that don't have a +5v connection. The problem that I am having is I think insufficient debounce. I don't think it's the 4-steps per detent problem, as i can sometimes get it to go up by one, but usually not. Any ideas for this, other than to use better encoders?

Regards

A couple of capacitors.  The dashed resistors are not required.
