[RFI] Is BPL readable?

[Mel Crichton]

I am not a computer expert, nor do I profess to understand everything about
wireless digital modes (the only digital mode I use is CW and VHF packet)

If BPL signals are actually radiated from the wiring carrying them, can they
be intercepted and read with a receiver and antenna (kind of like reading
WiFi now)? If so, would that create a security issue?

Just wondering..
