40 meters has been pretty ugly looking here in Central PA for the last week or so. Some very broad band stuff. an odd looking signal around4500 KHz shows up as well. Noise floor is pretty high as well. Anyone have any ideas?

wow.  Have you or a neighbor turned on their pool heater, gotten a used plasma TV, installed a new Solar Power system, or plugged in an RV/Trailer shore power cable?

I think it could be something like that, Ken. As luck would have it - it went away. Noise floor went from -85 to a flat -100, and 40 meters is hopping. With no one else seeing it, it must be local. I'll have to do some detective work and see what time it comes and goes. I'll have to check out our spa, cuz that has a circulation timing.
