      Interference from BPL and HomePlug transmitters:

      Some Broadband Over Power Line (BPL) and in-building powerline communications systems (PLCs) use HF and low VHF spectrum for transmitting signals which radiate in the general area of the power lines. Some of these systems have voluntarily conformed to the HomePlug standard which uses "spectrum notches" in most of the HF ham bands in their effort to mitigate some of the interference they cause to hams. However, the existing HomePlug standard does not provide spectrum notches for the 5MHz channels. The USA FCC requires that any new BPL systems have the capability to notch out frequencies whenever they generate interference to licensed services. However, in practice, it is has been difficult to get BPL systems to deal with interference complaints.

      For reference purposes, here is a list of the USA FCC-authorized BPL (Broadband over Power Lines) transmitting bands for USA
