writes: "KØHB" wrote in message link.net... "Jim Hampton" wrote Just out of curiosity, do you have an idea of how much power the Navy uses on the VLF stuff? I don't know current QRO, but in the 70's the COMSUBLANT transmitter at Cutler was 1,700,000W on 15.9KHz and the COMSUBPAC transmitter at Jim Creek was 2,200,000W on 17.1KHz. The ELF site at Clam Lake is reportedly engineered for just under 1,000,000,000W at somewhere just above powerline QRG, 75Hz if I remember correctly. The antenna is just under 29 miles long. 73, de Hans, K0HB Hello, Hans And *we* are paying for it ![]() Those are *big* qro rigs LOL Sort of. 2,200,000W looks like a lot -and it is a lot, in the world of radio transmitters. 2.2 million watts! But compare it to other technologies.... 2.2 million watts is only 2200 kW. At 746 W per HP, that works out to just under 2,950 HP. You could get more than that out of a single 1950s era diesel electric railroad locomotive, or a WW2 bomber - or about a dozen SUVs. Compared to the power of even a "small" USN ship or submarine... The 1 gigawatt ELF system is a bit bigger, of course. Count the cars on the Genessee Expressway where it crosses Jefferson Road at rush hour and see how quickly you get to the million-horsepower mark... 73 de Jim, N2EY |

Subject: The Game's Afoot!

Yep - Puerto Rico CAP is their correct State Wing callsign. Like Florida CAP where you are, or WHITE PEAK where I am. I'm not in Florida. I DON'T see ANY reference to any Part 15 or other unlicensed devices being employed or reported. Nor do I see any PLMRS, GMRS, or MURS systems. (Certain posters here insist they play a "major" role in "emergency comms"...Guess they will be in the NEXT exercise...?!?! In all fairness, the frequencies posted were in relation to a military exercise and to an exercise of a radio net oprated by the civilian government in support of said military exercise. This is far removed from the type of "emergency comms" in which GMRS, MURS, FRS, and Amateur stations would be involved. That one wasn't on you, John. Certain other posters have "insisted" that those radio services are "major" contributors to "emergency comms". They have yet to establish any validity for those claims. 73 Steve, K4YZ |

(FRS isn't under Part 15 either) One-way communications has been provided in emergencies for decades by broadcasting (also not under Part 15). In real emergencies the Public Land Mobile Radio Service (PLMRS) radios have been invaluable for local government and utility and medical aid agencies. (PLMRS isn't under Part 15). I think maybe you're half right, Len. believe it or not, even my ham rigs are Part 15 devices and come with the usual Part 15 warning sticker on them. Part 15 regulations apply to INCIDENTAL EMITTERS such as receivers, data couplers (if you have software controlled anything as a peripheral) and so forth. The stickers are there by the manufacturer and are intended to make the buying public believe in the sanctity of the product. :-) Remember the radios and TV sets of old from brand [which] which said "For best results always use [which] tubes?" :-) The Parts of Title 47 C.F.R. that apply to various radio services are listed after a link on the FCC Office of Engineering and Technology page. Under those parts one gets a link to the GPO which has the PDF repros of all the Parts of Title 47. The current issue date at the GPO (Government Printing Office) for Title 47 is 1 October 2003. That facility is a lot better than buying the same thing in hardcopy from the GPO. The last of five volumes of Title 47 (Part 80 to end) cost more than $50 even if shipping costs are free. The GPO does accept VISA and Mastercard and can take orders over the phone for local GPO outlets. The transmitter on cell phones (which are radios, not telephones), CB rigs, FRS/GMRS/PLMRS radios, and ham rigs are covered under those portions of FCC regulations that authorize the user to operate the transmitter (part 95 for CB, part 97 for ham, etc.). However, the receiver portion of the device is covered under Part 15. True enough. Problem is, nursie doesn't know which Part is which and becomes emotionally unstable when opposed to any of his postings. It is very inaccurate to state anyone has "insisted unlicensed devices play a 'major' role" in emergencies. Those radios ARE used by emergency communications groups in real emergencies. As I said, I did not see the original posts, but I am aware of instances where such equipment is used by governmental and emergency services personnel, as well as by ARES/RACES and other "civilian" EmComm groups (like REACT). Nursie doesn't want to see that. The original ranting and raving against anything "unlicensed" came from a mild comment by Brian Burke in here over a month ago. There's two worlds being discussed in here. The major one is reality - where you and I live - and the fantasylands wherein all the existing radio communication infrastructure fails in any emergency, only ham radio being able to save the day. Not only that, REACT grew through CB radio and the fantasyland livers think that all CB is evil, wicked, mean, and nasty, unfit for proper morsemen to ever approach let alone use. CB is unlicensed, of course, therefore it isn't any good since no test need be passed to operate one. :-) You and I know that most real emergencies are very local in nature and those can be aided by relatively short-range radios having 2 to 15 mile ranges. Those can be any of the presently unlicensed radios as well as licensed, such as PLMRS. Unfortunately, the vast majority of messaging in here, other than the "learned" pontificating of political pundits, involves arguing the fantasyland worlds of the various angry PCTA or those who wish to seek gurudom of the newsgroup (and whose words are golden, never ever to be talked against). Unless one is a regular reader in here it is difficult to follow some threads...even those that don't evolve into the flame wars you see. :-) |
