Just out of curiosity, has any other wall wart or other device been plugged in near the px3-kx3 recently?
Interestly enough, just this morning I saw new noise I hadn't seen before. It turned out to be a wall wart that was charging a car booster battery pack and it was about 4-5 inches from the kx3. I moved the kx3 away from the wall wart about 10 inches and the noise reduced. I zoomed the PX3 in to a 2khz span and I saw a spike at 60hz, 180hz, and 300hz symmetrically about the centre frequency. I moved the wall wart to another plug about 3 feet away, no more qrm. Hope this helps you.
