[Healeys] noise supression

[healeymanjim at hansencc.net]

i have an old sears positive ground radio in the bj8 and lately i have noticed a lot of static.  tried a new ariel. no luck. have copper center wires and resistor plugs.  when engine is shut off the fm is really ok, but am still wonky.   underway, the am is really staticy unless it is a really strong station.   i also tried different speakers with no luck.  i have given up listening to it and just wear earphones with am/fm.  works better anyway.   hjim
