It's not coming through your antenna. I see the same thing here in north Texas, especially if there's not much in the way of received signals and often at power-up. It doesn't seem to matter which band the radio's tuned to. It's definitely some kind of pickup within the P3 box, probably from an internal switching power supply. When it shows up I can move it around and make it come and go by putting some pressure on the top of the enclosure and flexing it a bit. I've always intended to crack the case and see if I could get the noise to appear and maybe fool with cable dress to see if that's the cause. It's not enough of a problem to get me to put it at the top of my agenda.
