I live within less than a mile of a major AM and FM radio station. When playing at church(which is closer to the stations), I've been picking up radio big time. After unplugging my guitar cable from the PA system, the radio station went away....which leads me to supect that it's the cable which is picking up the interference. Thing is, I'm using gepco x-band cables which are supposed to be double sheilded to prevent this type of interference. The pastor told me that he had tried several higher end cables before and had the same problem. When he switched back to the cheapies...the radio noise disappeared. So are higher quality, low capacitance cables more suseptable to this? Is it some brands but not others? I'm going to take my old cables to next rehearsal and see if that cleans things up.
