It disappoints me that the ARRL has taken an "I'm alright Jack" attitude to this by saying it doesn't affect amateur frequencies, when in fact it is going to hurt LOTS of other parts of the spectrum. |

And please, please think about the children and their 49MHz remote controlled toys.

Ah but it's NIMBY.  The businesses, federal, state, and local governments, law enforcement agencies, and various industrial radio services can take on the BPL Fan Boys now.

It has been the ARRL's stance from the beginning to strive for protection of amateur radio spectrum only. BPL interests would probably try to invalidate ARRL's issues with BPL and amateur radio spectrum if it started complaining about other services that it had no stake in. I tend to agree with them, though it's sad other services have basically done little to nothing to protect their spectrum.
As I mentioned two articles ago, Current has been very successful with the Cincinnati trial, with no unresolved interference issues. TXU did have an earlier trial with Amperion that had unresolved issues and was deactivated before the FCC could take action. I don't recall TXU ever fessing up to the interference, but their decision to go with Current says a lot. |

Who uses 30 - 50 MHz? Many State and local Law enforcement agencies and highway maintenance agencies, not to mention a host of other public service agencies and industrial users. |

There really isn't that much use of the 30-50 Mhz "Low band" any more. Most of the state police agencies that used it are long gone to trunked, million dollar Motorola garbage.
Of course, when they finally auction off the analog TV VHF spectrum and move public safety to 700 Mhz, all those million dollar Motorola systems will be so much scrap and the equipment will hit the surplus market. I can see the hams licking their chops now. Mobiles and HT's for a song, trunking systems on the cheap....Hams will finally get to use some of the UHF and microwave spectrum they have. |

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.

This is a totally anecdotal statistic (no link provided, standard disclaimers apply ), but I know there's at least one antenna manufacturer that is still pumping out about 2000 low band VHF base station/repeater antennas a year, so there's still a lot of use. Like most things technological, trends are cyclic. You'll see low band VHF become sexy once again after the higher bands get too congested or the county $100M high tech system fails.
I don't see the FCC reallocating UHF or microwave spectrum to hams. Hams have plenty of UHF and microwave to work with now. |

Re: Disappointing
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. |

The American Red Cross uses 47.420Mhz as its primary freq.
My county Sheriffs Ofc uses 460Mhz as primary, but 46, 41, and 42Mhz as tactical channels.
Florida Dept of Corrections uses 45mhz.
Florida Dept of Transportation uses 45 and 47mhz.
Florida Highway Patrol still uses (although not near as much as they used to) 45mhz across the state.
And lets not forget about all the fast food joints. The menuboard->headset freq of 95% of the joints is below 40mhz.
Theres these and a crapload of other agencies that use sub50Mhz for their primary communication, not all of which have the benefit of a large body like the ARRL on their side.

| the only interference to BPL are the hamsters
UPLC and the BPL companies want to work with them... but they won`t cooperate.... that`s why ... U.S is lagging behind other countries in the broadband arena !!!

They should know better than this, that Hams are not the only ones that are affected by BPL. And besides, it probably will kill the 6 meter Ham band [50-54 Mhz] |
