[TenTec] ARRL's BPL NPRM response is out

[ac5e at comcast.net]

Well, I found some very wide range digital racket from around 14.3 up to above 18.1 - beam heading 30 degrees east of north - while listening for CW DX on the 17m band. This stuff had a good bit of QSB but when it was peaking at S5 it sounded very much like the BPL audio clips. So I am pretty sure skywave propagation of BPL is already happening. 

Another point that does not get the attention it should - probably because it's going to be hard to quantify - is interference to BPL from "intentional radiators" such as licensed Amateur and commercial services. I get complaints of TVI when my local power company's service trucks are working in my neighborhood - and when the police or fire department use their two ways within a block or two - and I do not see how the very cheap BPL modems are going to keep from blocking from any moderately strong signal in the HF-VHF range.

Even IF the utilities are willing to keep our frequencies clear that will solve nothing if we cannot transmit without blocking our neighbors internet connections. I already know what happened when a CB'er's illegal amp blocked a satellite dish's reception. Semiconductors ARE diodes, and diodes rectify. Whiteout! Followed by a shootout. 
 
I don't want to have to answer my door wearing an armored vest with a shotgun in my hand - or call the county sheriff whenever a stranger arrives in my driveway. And that's exactly what will happen if the Jukes down the road think anything I own or operate might interfere with viewing the notorious Paris Hilton tape.
