    Had a similar problem, found it with a portable SW radio. Turned out to be a switching power supply in my neighbors swimming pool controller. The fact that the dipole antenna does not hear your interference probably means the source is closer to the vertical than the dipole. Once you find the source then a plan can be employed to eliminate the RFI.
