Really bad idea. The market works better without government interference. Brilliant stupid canned comment. California has a government. The US has a government. I'd rather we work issues with our elected Federal representatives than have California start pushing at the state level. States are more responsive than the feds, Besides we are a federal republic, hence the states should be taking back what the feds have grabbed. Naïve point of view. Not at all, and accurate statement reflecting current affairs with our federal republic. The feds grabbed? Yep, common knowledge Do you recall how the state's representatives become feds? It is a mistake having popular elections for the state Senators. Kind of destroys the purpose of the Senate. - Hide quoted text - - Show quoted text -- Hide quoted text - - Show quoted text - Yep - The US Senators should be 'appointed' by the King of the State {Oops Governor} cause their should represent the Big {Money} People. And you think that the representatives and senators now publicly elected represent the people. Come on, why do you think there are so many lobbyists in D.C. the divine right of money & the golden rule : those with the gold make the rules ~ RHF |

DTC hath wroth:
Brings back fond memories of the "RCC wars" (radio common carrier). In Texas, they were all pretty cooperative with reciprocal roaming. In California, specifically the Orange County area near Smog Angeles, the RCC's were perptually suing each other. About 5 years ago, I got an invite to do a deposition on a running case that started in about 1970. The original parties are dead or gone, but the new business owners have picked up the torch. Rates in the '70s were typically $40 a month which included mobile radio rental and unlimited minutes and free roaming. Denton Texas with the two universities had like 300 users in the early/mid '70s. When the rates jumped from $20 to $50 per month (on *TWO* VHF channels), it dropped to like fifteen users. L.A. had a 3 year waiting list for VHF channels. My license was from Nevada. The Secode was indeed much easier to program than the Motorola control head. Program? I just had a Secode control head in my car connected to an ordinary G.E. Progress Line on the shop channels. I was just trying to impress the ladies, not talk to anyone on the phone. If I needed to make a phone call, I would use one of the ham systems. I eventually replaced the Prog Line with a T1234 mobile phone using the same control head. Of course I would never whistle off the connect tone of an incoming call meant for another user and grab the channel when it went back to idle. I had two pieces of brass pipe tuned to 1500 and 2805 for the purpose. Incidentally, my senior project in kollege was designing an all solid state Secode Selector. The original Secode model 70 or 90 selector was a mechanical marvel and a nightmare to fix. I eventually upgraded to the all solid state Motos and smaller control heads. That would probably be a Motorola Pulsar. The T1234 was solid state, but with one pair of crystals per channel. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

Yeah, right - I mean ,who needs insider trading rules from govt interfering with commerce, dratted FCC saying who can and can't use bandwidth etc etc... *sigh*. -- Mark McIntyre |

Are you attempting to say the audio bandwidth of a message network channel is greater than about 3 kHz? |

IIRC from my work with those systems, about 300-3600 Hz. Strictly human voice range, not meant for hi-fi. Special lines are still available for hi-fi use as audio STL's. I engineered a remote in Chicago a number of years ago, and the client wouldn't spring for ISDN, or equalized lines. ATT provided a POTS line and we got 8k analog audio out of it. Then again, we were next to an ATT store. Similar performance was observed at my condo in Heather Ridge. Here at the house, not two miles away, I'm lucky to hit 14.4 modem speeds, and 3k audio on a good day with my POTS line. Guaranteed performance, you're right, is only 300 to 3600Hz, and 14.4k modem speed. But real performance varies from company to company, CO to CO, line to line. And surprisingly good audio and high modem speeds, are possible with POTS technology. The instruments, themselves, are bandwidth limited. But the lines are often, but not always, much wider than the instrument. That's why, when addressing the phone with a hybrid, or repeating coil, directly, I have always been able to get passable audio on a POTS line. With AM audio bandwidth limited anyway, I could usually exceed the stations audio performance from the field and you couldn't tell we weren't using high performance lines. But that experience hasn't been limited to AM. I've been able, when lines were clean enough, to hit FM stations with audio wide enough, that the losses were ignorable. Hardly negligible, but certainly ignorable. And in at least two cases, better audio than was possible with Comrex, or with the POTS digital dialup systems out now. It just depends on who's providing the line, and how it's routed. BTW, equalized lines are being phased out. They're still available, but carriers are moving to make them prohibitively expensive to install and maintain, anymore, and carrier noise, which was never a problem before, is becoming a problem now. It's easier, more cost effective and requires less installer activity to drop in an ISDN line for broadcast. So carriers are really pushing that. Not that they're making it that much easier on the broadcaster. When I put in my ISDN link here at the house, I very nearly had to wire it for them. When the Florians owned WNIB, Bill got tired of all the carrier noise, and administrative crap that went along with his equalized studio-transmitter lines, and had ATT install a second set of control loops for his remote transmitter control. Control loops are copper, unequalized, and are designed to carry control voltages, down to DC and control databus output. They're basically just twisted pair. And dramatically less cost than broadcast lines. Bill got his own equalizers and set up his own equalized lines on the extra control loops and put his studio-transmitter audio there. It was the sweetest sounding audio on the dial. Right up there with WFMT, but less limiting. ATT threw a fit. Control loops are NOT for carrying program audio. Bill fought them on it. And never did return to ATT broadcast lines. He and Sonja eventually sold out to Bonneville for nearly a half a billion dollars. Sometimes the bear gets you, sometimes bear steaks are so tasty at the end of a long ride. |

But I'm using ISDN as a studio-studio link. So far, no one has suggested to me that it's not going to continue. |
