Well, I was the one that brought up this RFI business. turns out the PSU is likely not the cause of my RFI.
I pulled my vehicle into the garage and plugged in an AC power supply to the wall and the interference still existed.
I get AM and AM HD great though!
FM still sucks. Considering I'm running an older motherboard with a P4, perhaps a newer generation of technology will help.
The current case is steel. http://www.newegg.com/Product/Produc...82E16811154062
There is a vent in the top. Maybe that's letting the RFI 'bleed' through.
This is in an Explorer. Computer is in the back. The radio is under the back seat.
@joshuo. I heard that some people like the OPUS better. I was going to go down that road until I had the same results with an AC PSU.
