No, you are trying to claim that there are no illegal operators on 6, based on your rejection to my claim that what I can hear on almost a daily basis is in fact illegal. I'm sure some of them are illegal, but my surity is not fact. Why not? Are you claiming that empirical observation is not sufficient? Are you now promoting the concept that if you are not "right there" and personally witnessed an illegal transmission that you can't factually determine that it was what it was? Is your zeal to trounce me over my opposing political views blinding your objectivity with regard to radio issues, which you have far better knowledge of? Your personal feelings are not "facts". No but my trained observations skills can be considered as strong evidence to the positive. Trained observation skills = Tarot cards. So, you're telling me that you can't listen to a channel and pick out who the most blatant illegal operators are simply by the sound of their rigs, and by the splatter they produce? Would it help you to know that a spectrum analyzer connected to the I.F. of a receiver confirmed my initial observation? I never claimed to be able to make a quantitative evaluation, only a determination that the transmissions were illegal. Making a personal opinion that "channel 6 harbors the dregs of society" Yes, that part is my personal opinion. Why is -this- your personal opinion and not fact? Because it is simply my opinion. What constitutes a "dreg" is subjective. What happened to your "trained observation skills"? They are limited to technical evaluations of radio signals, which is NOT subjective. and claiming it is nothing short of empiracle evidence that illegalities occur is jovial. That you once again think that you can somehow claim that these illegal operators do not exist is ludicrous. Nobody suggested that illegal operators don't exist. The question is your standard of proof, that what you claim to be illegal transmissions are illegal IN FACT, not in your opinion or belief. If you hear a loud noise and turn around to see a souped up car buzzing down the road at a high rate of speed, far above the posted speed limit for that road, would you not be able to determine as a fact that the car was being operated illegally? No, you could not determine just how fast the car was traveling, but you could easily tell from the excessive noise, and the rate of speed as compared to the other (legal) cars, that this one was illegal. If you are attempting to discount empirical observation as an invalid method to determining facts, then there are a whole lot of scientists who will be sorely disappointed. Starting with paleontologists all the way to astronomers. We don't agree politically Frank. That much is true. But don't let that one facet taint your objectivity in other subjects.

When the dx is running strong, that is exactly what people are trying to tell you. The "DX" has nothing to do with the amount of splatter and the distortion a signal may have. It has everything to with it. For the amount of times you professed to having talked skip on the freeband, followed by recent denials of you talking skip, you should know that on MANY occasion, a signal can be severely wavering from an S1 to an S9 (for but one of many examples),,,when that signal is coming in at an S9, the splatter may be intense if you changed the channel and went one up or down. When that signal is coming in on a wavering S1, you will hear absolutely nothing on your next channel. Once again, the wavering is a direct result of...taa daaa....skip. The only effect that "DX" may have is heterodyning of co-channel signals. In any case, when my observations were made, the "DX" was not running heavy enough that a clean sample of any particular transmission could not be made. You can qualify it away now, but your original claim is still bull****. _ I find it absoutely astounding this is lost upon you That's not surprising considering you once tried to tell me (and the group) that a 4 watt skip station 1000 miles away could potentially walk on top of a 4 watt station a half mile away, Absolutely. In fact, I have taught you many things regarding HF propagation and communication law of which you have no clue. totally disregarding the effects of R.F. .path loss. Never. That last part was added desperation. - Coupled with your claim concerning roger beeps and echo on cb being illegal (they're not) merely because you were unable to locate a rule specifically permitting their use, and it merits There are specific rules which specifically prohibit devices used for "entertainment" and "amusement" purposes. But only you continue to err and place such in that category. Your argument is with the FCC, not those of us who are able to correctly understand their law. There is also a specific rule which outlines permitted tone signals. A Roger Beep is not listed under permissible tone signals. Following simple logic, since there is no valid rule which permits a particular device, then the device defaults to one of "amusement or entertainment" status and is prohibited. That isn't simple logic, that's but an openly biased albeit incorrect interpretation based on nothing more than your past stated disdain for such items and your ignorance of the law that governs your hobby. 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. Only by yourself. 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. Not only would I never make such an invalid comparison, I disagree with such a statement. Email the fcc and ask them about your claim, Dave. But the fact remains that they are prohibited by the rules. Insisting on remaining ignorant is your right at all cost. Irony: When some of those licensed for communications know the least about their chosen endeavor. Bigger Irony: Someone with obvious comprehensive issues chastising others for the same flaw. Dave "Sandbagger" This is quite simple, really....me: 100% correct..you: 100% wrong. |

Splatter is the result of a dirty transmitter, Bleed,,splatter,,,,you're wrong, ya' know..a dirty transmitter is but ONE example.............once again you incorrectly claimed that skip does not affect splatter, and are trying to distance yourself from your espoiused ignorance only after you have been corrected, Several educated cbers and hammies have clued you in, but as always, you aer set in your ways and you DO have the right to remain ignorant, depite several people providing you the correct information. and those products show up as a "comb" of harmonics which decrease in amplitude as you move farther away in frequency from the fundamental carrier. If the fundamental signal is +10db over S9, then those distortion products will be plainly heard if they are only 10 db or so down on an adjacent channel. You are arguing with yourself, again. Try this: Your claim of dx has nothing to do with splatter is bull****. Your claim that ony a dirty transmitter splatters,,is absoulte bull****. That same splattering station, when he fades down to an S1 signal, is now so weak, that his adjacent channel splatter products are now under the noise threshold of the receiver. THAT is why you don't hear them. This is quite simple, really....me: 100% correct..you: 100% wrong. When it comes to radio theory, you haven't been correct about a single thing. ....said the self-professed "radio Technician" who has been in radio for "over twenty years" and maintains incorrectly that roger beeps and echos are illeal on cb.

DX has everything to do with DX splatter. He's right, Dave. You can receive more than one skip signal from the same transmission, and their phasing can cause intermodulation distortion in any RF stage of your receiver. All that's required is enough non-linearity in just one stage and the signals will modulate each other. The result is what appears to be splatter but is really a fault of the receiver. Happens all the time with cheap shortwave radios. And DX doesn't have to be up to get a good signal -- I have heard many clear DX signals from seemingly dead bands. |

DX has everything to do with DX splatter. He's right, Dave. You can receive more than one skip signal from the same transmission, and their phasing can cause intermodulation distortion in any RF stage of your receiver. No dice Frank. 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.
