Hi Rick, Respectfully, since I already had this dialogue with Mr. Hare, there is no sense in him repeating it through you, especially when he isn't around here to discuss it himself.
But let me point out, that I personally have designed DSP-based products that do precisely what we are talking about here. All the engineers said, "It Couldn't Be Done", before we did it. There were many nay-sayers before we did it, with much higher levels of DSP expertise in this area than Mr. Hare, and they all had to eat crow. I assure you it is possible to make BPL-Busting Modes for ham radio. Whether or not Mr. Hare and his ARRL buddies want hams to do it, and are creating a smoke screen to discourage it, is technically moot.
