Hi Bob, That sort of threat would not be very effective against me :) When I originally proposed this subject, digital communications for hams to communicate through BPL interference, some of the higher ups in that organization were none too happy with me, either. This led to a curious interaction with the guy spearheading their BPL interference testing. He told me that what I was talking about was "an engineering impossibility" and "I didn't know what I was talking about". At one of my companies, I designed communication systems that solved much more severe co-channel interference problems than BPL. One of those products, based upon these same principles, received a major technology design award several years ago. I sent him one of the product brochures. I have not heard from him since :) Presently, BPL has literally put some ham operators off the air. Other semiconductor-based EMI sources are having similar effects. Restoring these operators to being on the air again is good for ham radio. It might also put the BPL systems on notice, since they could no longer rely upon their interference effectively silencing hams to alleviate their own weakness of EMI susceptibility to RF ingress.
