Read the article: 30-50 MHz
I saw that wise guy. What I was asking was what services are affected? And that isn't in the article.
Lower VHF TV channels, business two way radio, and in some areas low band VHF public safety. I say "in some areas" as a lot of public safety is now in high band VHF ( ~150 Mhz) and the 800/900 Mhz spectrum. You'll see low band used in more rural areas or in areas with less money or incentives (like frequency congestion) to move public safety to other bands.

The thing is that it doesn't MATTER what's in the 30-50 MHz spectrum. BPL will create a lot of "splatter", everytime it hits a transformer, ever cable joint etc.

It's a ridiculous technology.

I won't disagree that it's ridiculous technology, however I'd rather have this in 30 - 50 Mhz than plunked on the spectrum below 30 Mhz. Much of the communications in 30 to 50 Mhz is FM and local communications, often using repeaters and/or used in vehicles with electrically noisy engines to begin with. Receive signal levels are in general higher that what you work with on HF (1-30 Mhz). On HF, one often receives signals just above the noise floor, something most BPL proponents just don't understand.
