DX has everything to do with DX splatter. No, it doesn't. Dx is simply an enhancement of the atmosphere which allows a signal to propagate farther then normal line of sight. It does not add "splatter" to an otherwise clean signal. Ah, that explains everything. So when a normal channel has maybe 5 to 10 operators, add another 100 because of skip conditions, of course there will be some running clipped & mod radio's, you don't think that enhances the splatter? Not to any one single radio signal. You are confusing heterodyning with splatter. So therefore it can be assumed that a roger beep and (even more definite) an echo box could be considered "entertainment" or "amusement" devices and, as such, are specifically prohibited. You can make the point that the FCC doesn't care enough to make a case about these things, and I would probably agree with you. But the fact remains that they are prohibited by the rules. We've gone over this before Dave, your wrong. I have referenced two part 95 rules which address both the issue of permissible non-voice transmissions and also prohibited transmissions which include devices which are used for entertainment and amusement. Conversely there are no rules which specifically allow either a roger beep (and other noise makers) or echo boxes. Since neither are defined under permissible non-voice transmissions, it can reasonably be concluded that these devices would be considered amusement or entertainment devices, and as such prohibited. You tell me I'm wrong, then please prove it by providing the rules which allow these devices. If I showed you CB radio's being sold BRAND NEW with roger beeps, will that do? It will tell me that there are a few companies which are willing to play loose and fast with the rules, until they are spanked for it. Galaxy radios are notorious for catering to the illegal freeband market. It's no surprise that they push the limit. Knowing that the FCC is not all that interested in small CB rule issues, they take the gamble that they won't be judged. They're probably right.... There is still nothing in the rules which allow for devices that can be considered entertainment. Dave "Sandbagger" |

The differences in phase angles of the received signals can cause either an addition to or a subtraction from the fundamental signal. But it does not cause it to splatter. No it doesn't, and that's not what I said. I said that a non-linear stage in the receiver can turn that fading into what appears to be splatter. If you want an example I have a couple cheap shortwave radios that do exactly that; you pay for shipping and you can examine them all you want. You may very well have an example of what you've described. But that doesn't mean that I do, or that I am incapable of distinguishing between receiver quirks and actual on-air splatter caused by an illegal transmitter. In many cases, I've used different radios (I have enough of them) as well as test equipment to make my determination. Do you really want to argue the point just because you're smarting with me right now? You, of all people, know what an illegal operator sounds like. Dave "Sandbagger" |

The effect you have described is commonly referred to as "multipath". The differences in phase angles of the received signals can cause either an addition to or a subtraction from the fundamental signal. But it does not cause it to splatter. A special form of this is called "selective fading" which can cause different parts of the signal to fade differently, which can distort the audio. But this is not "splatter, and will not make the signal "bleed" more. Heck the HF ham bands are almost always utilizing skywave propagation. If what you say were true, then the ham bands would be virtually unusable due to all the signals splattering across the band. With the exception of a few bad apples running some illegal equipment, this is normally not a problem. All that's required is enough non-linearity in just one stage and the signals will modulate each other. I have never seen this happen in any of the quality receivers I've owned over the years. Unless the signal is in motion (doppler effect) the frequency will remain the same even if the phase shifts. Since all the multipath signal frequencies are the same, there will be no mixing products generated. If that were the case, then any group of signals, local or skip, would do the same thing. That's not something that you'd want in a good receiver. But you can't pin the faults of a bad receiver design on atmospheric phenomenon. This is almost as hokey as saying that a certain antenna will make you sound "louder". Propagation, like antennas, are passive. It only radiates or re-radiates a signal. It does not modify it . If a signal is clean, then the propagation will propagate it as such. The result is what appears to be splatter but is really a fault of the receiver. Happens all the time with cheap shortwave radios. Ah! But why do you assume that I have a "cheap shortwave radio"? What happens when you put a low noise GasFET preamp behind a bandpass filter and then into a spectrum analyzer? Surely you know what splatter looks like on a spectral display? And DX doesn't have to be up to get a good signal -- I have heard many clear DX signals from seemingly dead bands. A clear, and stable DX condition will not distort a radio signal. A station which is backswinging wildly, with fuzzy distorted audio, and splattering 3 channels in each direction, is running illegally, regardless of the fact that the FCC hasn't yet cited them for it. Yeah. So what? But was I LOUD? You were 10-8 and straight across my duck pluckin' end that's for cotton picken real. ;-) Dave "Sandbagger" |

DX has everything to do with DX splatter. The only thing DX has to do with DX splatter is that if "DX" isn't running you wouldn't hear it. Probably, but if you have a 100 radio's and a third of them are running their modulation clipped, then you will hear it even worse, correct? Splatter or out of bounds emissions are those falling outside the normal bandwidth of a signal and are the result of modulation. Correct DX doesn't cause splatter it allows it to propgate farther. Correct. When you have a lot more radio's trying to talk on one freq, don't you think that it will now increase your adjacent channel splatter? Ok, so if I understand you correctly, you are now making the case that I cannot identify the exact station which is creating the splatter due to the sheer number of competing stations. Ok, you have a valid point in some cases. In many cases all you have is combined "noise", and it's impossible to distinguish any one individual. On the other hand, especially on channel 6, there is always one or two stations which stand out head and shoulders above the pack. You can plainly hear his splatter on adjacent channels. Those are the guys who I base my observations on. Remember, I never said that *all* the stations on channel 6 are illegal, just the loud and proud ones. Then there is also the issue of aggregate signal differences. If the average noise/signal level on most of the 40 channels is running around S8, and while on channel 6, it is +10db over S9, that suggests that the average power level of the users there is at a higher level than those on the other channels. Skip doesn't favor any one channel (in a band as small as the CB band) over another so the conditions should be the same on all the channels. Dave "Sandbagger" |

Well gee Dave, I'm just suggesting there's another possibility for the splatter instead of illegal behavior. You know, kinda like your suggestions that there were other reasons for voting irregularities in Ohio. How can you be so 'open minded' on one topic yet be so quick to condemn on another? ----== Posted via Newsfeeds.Com - Unlimited-Uncensored-Secure Usenet News==---- http://www.newsfeeds.com The #1 Newsgroup Service in the World! 100,000 Newsgroups ---= East/West-Coast Server Farms - Total Privacy via Encryption =--- |

I made an observation, based on trained skills. It's enough to tell me the truth. And did make any observations, based on trained skills, when you determined the "truth" about Kerry's military record? ----== Posted via Newsfeeds.Com - Unlimited-Uncensored-Secure Usenet News==---- http://www.newsfeeds.com The #1 Newsgroup Service in the World! 100,000 Newsgroups ---= East/West-Coast Server Farms - Total Privacy via Encryption =--- |

That depends on what you mean by "over-driven" Good Gawdomighty,,,,,,here comes N3CVJ to tell *you* what you meant by "over-driven". Davie applies his own definitions to words that everyone else has no problem comprehending. When your thought processes (and I use the term loosely) are comprised of a series of binary thought patterns, Only you weren't addressing me. Pay attention. But holding with that, you just made the comment in another post that one can not possibly know what your thought process is, but of interesting note is the self-professing notion that *you* are capable of such a feat. where everything is either black or white, I can see why you might think that. But if you actually KNEW something, (other than "CB Science") you'd know that the term "overdriven" has many applications, as illustrated by my earlier response. Dave "Sandbagger" Only you took issue with the term, Davie. |

Davie lobbies hard telling the world that just because the FCC told the world N8WWM was jamming repeaters, it's not evidence of guilt. It is not evidence of guilt they charged him with nothing. N3CVJ says otherwise. He said his empirical observations are evidence of guilt. and landshark said you must have a jury of your peers decide you to be guilty. Landshark is correct. However, with certain charges brought by the FCC, exceptions abound. |
