RE: How to picture tutorial. Removing RCA jacks. - spylinker
But you probably have no way of measuring the radiated EMI/RFI from the cables. With the shields disabled, radiated noise may increase. Some external devices, such as the R/C gear, might be affected. Without substantial testing, it is all an unknown. The extra couple minutes spents restoring the unused shields is not a big deal and that is why I recommend not cheating on the recipe.
I agree that it may not matter in many situations. It is just hard to know when it will matter.
