I use a 'boombox' portable radio in my garage and usually listen to either AM radio or sports broadcasts. I usually have some audible interference through the radio speakers when I have my 8' fluorescent strip lights on. I keep the radio plugged in to the outlet as it eats up batteries although my receptacle circuit is on a different breaker than my lighting circuits. Also I have both cold weather ballasts and non-cold weather ballasts and it does it on both. Is there any kind of grounding or antenna enhancements I can do to minimize this?
