said by MysticGogeta  :Im sorry but id rather have more compatition in broadband then haveing a radio frequency i never use Well, duh, but that's not the issue. When you have radio signal coming off of a wire and bleeding into free space any and all frequencies could be impacted. So if you're willing to give up your emergency services (police, fire, ambulance, disaster recovery)... |

So the ARRL, ONCE concerned with wise spectrum use for ALL frequencies, has now whored itself to a BPL carrier... I can't recall the ARRL ever being concerned for all frequencies, although maybe remotely shortwave broadcast since many hams are SWLs. Can you cite an example were the ARRL lobbied for non-ham spectrum in some official public way?
Many have said this before, but the one and only issue that ARRL and ham radio has with BPL is with interference to ham radio. If a BPL carrier can honestly fix that problem without smoke and mirrors, and not be continual thorn in our sides, hams have nothing to complain about (much to the dismay of trolls and ham bashers here). The NTIA documented the issues with aeronautical frequencies, and the FCC implemented some protection for them, but if it isn't sufficient, it's the fault of the NTIA and FCC and they'll have to answer for it. Commercial interests that will be affected need to spend their money to protect their interests, not that of ARRL members. Myself and others may argue that BPL on any frequency is a bad scene, but I'm not going to pay to convince an unresponsive, heavily politicized FCC to protect a for-profit business. The ARRL has made bad decisions in the past, but this isn't one of them. |

RC aircraft are usually regulated to 72MHz. RC vehicles (cars and boats) are 75MHz. There are other frequncies next to the CB band (27Mhz) and some frequencies at 49MHz (limited power.) HAMS can also use the 6 meter band for RC control. |

You DO realize that the ARRL is viewed as a quasi-honorable organization concerned with wise and correct use of the spectrum, right?
What this tells me is that the ARRL are money whores like pretty much any other organization I've run across in my too many years.
So the ARRL, ONCE concerned with wise spectrum use for ALL frequencies, has now whored itself to a BPL carrier...
Im not impressed.

said by MysticGogeta :Who cares get a cell phone or nextel if you want some walkie talkies its time to change There's always somebody that says that every time the topic comes up. To me isn't the issue of what spectrum they're using, it's that BPL should be confined to the wire and not bleed into the open air. If it's bleeding, you can be sure it's going to bleed all over the place because of harmonic frequencies and the like. An unintentional emmiter capable of squelching parts of the radio spectrum is a alarming.
I don't, however, mean to muddle the issue: ARRL should only be responsible for looking out for their own frequencies. |

Have you really thought that disappointment through? ARRL staff have agonized over it.
In the first place, with several million HomePlug modems deployed -- the modems used on HF by Current Technologies -- ARRL does not have a single report of harmful interference involving Amateur Radio. To ARRL's knowledge, there have been no reports about HomePlug modems filed with the FCC involving shortwave listening, even reports by amateurs. In Cincinatti, although some noise was observed by me on the shortwave bands, of 50,000 homes passed, there were no reports of harmful interfernce to Amateur Radio or shortwave broadcasting, even by the hams there.
The system deployed in Texas is almost certain to be the next generation of HomePlug devices. Under the FCC rules, it will have to have the ability to notch any spectrum as needed, so if there were to be interference reports by those other spectrum users, the manufacturer will have the ability to address them.
ARRL has standing to speak for Amateur Radio. The real disappointment is that the other users of the spectrum, groups like APCO and the international shortwave broadcasters, have not spoken much at all for themselves. In
the presence of their silence, ARRL cannot and should not try to speak outside its standing. If it were to do so, the BPL industry would pounce on that, claiming that these other radiocommunications users do not see an interference problem, but ARRL is making up one that doesn't exist.
They would then use that to try to completely discredit ARRL's legitimate concerns for interference in the ham bands.
The League has worked with these other entities and made its information available to them. All they would have to do to make good use of it is to do 10% of the work that ARRL has put into this effort, and to allow their speaking out to give standing to ARRL to be able to support them as they address their interference concerns.
They have not, and under the circumstances, unless your disappointment extends to being willing to lose credibility for Amateur Radio, ARRL must continue to work within its standing to speak for Amateur Radio.

said by sbrook :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. |

said by sbrook :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. The ARRL is essentially a trade association which is empowered to act in the interests of its members, and they should confine themselves to their proper constituency.

Re: Besides
The military is a big user of frequencies in the upper part of this frequency range. I wish they would not pollute the 6 meter region because it has some very interesting propagation characteristics. The 49 mhz area is one I have used when I was in the Army National Guard and we used to be able to talk from Camp Guernsey, Wyoming to Ft Carson, Colorado from our vehicles which is a range of just short of 300 miles. It is a very nice mobile frequency.

Re: Disappointing
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.

Re: Besides
said by Fatal Vector :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. 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. |

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.
