Oscillations and switching signals are not enough on their own to create RFI. They have to be radiated.
Shielding is a common way to reduce emissions (and also to reduce susceptibility to incoming interference). I always use twisted-pairs for my power cabling, and when I have to use ribbon cable for signals, I try to straddle the clock signals with a static signal, or ground, when possible. In extreme cases, which I doubt exist in nixie clocks, you need to use differential pairs. Ground loops are another source of trouble, which is why you want to bring all grounds together at a single point. If you have ground carried thru 2 or more paths, you may have introduced a ground loop if the paths are not identical. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
