[Spits] Radio Noise

[oldlbc at aol.com]

I'm going to upgrade the radio in my 71 Spit.? Not having done anything of this sort in about 30 years, does anyone have any suggestions as to avoiding or supressing the annnoying whine from, if I remember, is due to the alternator?? I seem to remember that you could a capacitor or something on the power line to the radio that would do the trick.

TIA
