There are filters for DSL lines so that only a clean signal gets to
an ordinary phone instrument. Are there filters for BPL (Broadband
over Power Lines) so that they cannot pass, and only a clean 60 Hz
wave gets through?
There would seem to be a need for such devices for secure military
installations, once the FCC's misguidedly approved BPL gets
widespread.
(I say misguided because BPL appears to interfere with ham radio.)
