ONLY if they reverse many rules!

The RULES say that BPL is NOT protected from interference, that it MUST accept
interference and cannot protest to the contrary.

Your friend ASSUMES that the FCC is going to suddenly tell FEMA, RED CROSS,
other legitimate HF spectrum users that they must shut down.

I don't think he is right. I do NOT think they are quite that stupid.
Close but not THAT stupid. It will never fly.

BPL will have to keep doing a a WHOLE lot of retries till it gets through, and will
lose throughput.

If BPL shows up in my town, I will PROMISE you that I will run
the legal limit on HF.
