Recently I had to rplc my AC blower and motor. After doing so, I noticed that I had to set my CB radio's squelch to a point that it's almost not worth having the radio. After consulting the local CB shop, I was assured that it is not "alternator whine" that can be filtered out using an inducted capacitance filter. Anyone know if those blowers can create an RF field large enough to fill the cabin with "noise"? The obvious fix: move the power supply wires to another circuit. That's already done, and had no effect. Complicated fix: anyone know how to filter the RF noise from my cabin? Thanks yall.
