Splatter or out of bounds emissions are those falling outside the normal bandwidth of a signal and are the result of modulation. DX doesn't cause splatter it allows it to propgate farther. |

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? |

It would only be worse because now you can hear the 100 radios. Splatter or out of bounds emissions are those falling outside the normal bandwidth of a signal and are the result of modulation.

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? Only because you now can hear more radios. skip doesn't cause splatter. Take the same 100 radios that were causing splatter when the skip was running (all stations running S9). Now move them all so they are local to you (again all stations running S9). From what you have said you believe the splatter is going to decrease ? |

It has been my experience that when skips running, you will have more incidents of adjacent channel splatter than when it's not. I'm sure "Skip" is not causing it, but it sure does "Heighten" it.

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" |

And just becuase of the sheer numbers of operators, legal or illegal the DX alone is helping intesify the splatter, because "everyone is trying to get into the feeding frenzy. On the other hand, especially on channel 6, there is always one or two stations which stand out head and shoulders above the pack. Maybe where you are, not where I live. Chaneel 17 & 19 have the most noice when skip is running. You can plainly hear his splatter on adjacent channels. Those are the guys who I base my observations on. Opinion, everyones entitled to one.
