Radio interference , lighting
Thanks for the suggestions, I finally figured it out. This is a new one for me. Several lamps on the top fixtures were loose (still working fine but loose). When I opened the fixtures to check the grounds the noise reduced by the time I got to the last one the noise was gone. My wife thinks when we loaded the hay loft in June we must have shaken them loose. The loft is on the other side of the wall. I have never run into this in the past so it can be something to look for once all the lamps were reseated in the fixtures the "static noise" is totally gone. No other problems found. I did check the ground rod with a clamp and the ground was a solid 2.4 ohms.
