| I'm all for it, if... ... they can find a way to make it not interfere (or interfere less) with existing technologies like amateur radio. As someone who is planning on getting a ham license very soon, I'd rather not see problems arise because of this.

| One picture is worth a thousand words Somewhere near the top of this post (»Re: I'm all for it, if...) moonpuppy posted a link to the ARRL web site. Here's the URL to a .wmv file from that site that "ya'all" should watch before continuing to drool over your dreams of BPL for the masses:
http://www.darc.de/referate/emv/plc/030103-PLC_Video_Fulpmes.wmv
The film was made in Austria, but no special language skills are required for interpretation - just look and listen and it will be obvious that BPL is not being promoted "for the people".
Remember that the FCC was established to protect both radio amateurs and the public alike. It's a two way street - not only does BPL have the capability of messing up HF and low VHF operations (and most likely many other bands as well), but those operations can likewise mess up your BPL nirvanha. The FCC's primary job is to manage allocation of space on the radio spectrum to prevent these type of problems from happening. Let's hope that the FCC acts in the public interest this time around.
PLEASE, take a look at the video and THINK about what is happening here...

| Re: I'm all for it, if... The interference is from the BPL signals.
Ever drive under power lines listening to AM radio? Notice how the radio becomes nothing but static? Realize that the power lines are NOT shielded and therefore will radiate the BPL signals all over the place. | |

| Re: I'm all for it, if... It basically affects all receivers (including those in 2 way radios.) The signals from BPL are so powerful, they make receiving any signals nearly impossible unless transmitter is much more powerful (we are talking close to a kilowatt just to start!) Right now, most public service and safety users in the 30-40Mhz area have transmitters in the 300 watt range. Get a fire truck or police car close to BPL lines and forget about that call from dispatch. All SWL (short wave listening) would be gone and even parts of the AM radio band would be useless.
The line itself is NOT shielded so the BPL signals not only travel on the lines but radiate out. | |
