i would bet money that you have an AM broadcast station near by within
1-5 miles away the music your hearing is from them bet you will hear it
on HF bands in differnt spots as well
i have the same thing here i have an AM Station on 1.430 and i hear it
on 14.300 and 50.056ish and several other spots as well as the AT&T
phone in the house
as for the engine noise it could be a factory or plant near by running a
piece of machinery
or the power company missed a transforer or unsulators
