<---I'm running two 12 Vdc fans in my Micor repeater. I use a 200 uh choke in each lead (+ & -) and a 1000 mf cap across them, on the supply side. I then use a transistor to control 'em and I have absolutely no noise whatsoever using this scheme. I suspect part of the problem is that most people forget to treat both supply lines and noise gets introduced due to ground loops and stray currents.
