There is a local on CH21 AM talking, he sounded good audio wise, but I could also hear him distorted on CH18, 19, 20, 22, 24 and maybe 25 as well.

Is this what splatter means?

Yes. That's the definition of splatter. More commonly referred to as splash. 73
Many CB radios don't have a lot of 'adjacent channel rejection'. Station could also be close by, which just lends to this problem. Could it be a dirty radio? Sure; there are plenty of those still floating about.
They may not have brilliant adjacent channel rejection but if you're still hearing them 30kHz away its definitely him.
Also if you have the noise blanker enabled on your radio in AM or SSB mode it makes them more susceptible to receiving splatter.

I'd venture to say there are more dirty radios (11 meters) then clean ones operating. Then factor in a CB amp (which are used by many of us chicken banders) and let the splash commence.73
That's splatter. Unfortunately some people believe that a powerful radio splatters and there's nothing that can be done about it.
I have a neighbor 3 miles away (uses a cobra 29) that can not hear me at all 2 channels away with 1600 pep at 8khz freq response. If I narrow the tx filter to 4k or less like a normal radio he can't hear me 1 ch away.
Then we have a local with an overdriven shit box amplifier (thinks it does 2kw because of his watt meter says so) wrecks half the band from twice that distance. Nice guy but just doesn't know any better. He loves to watch the watt meter swing and has been doing it too long. There's no helping him.

Cheers, I wasnt judging him, although he does come across as an ahole in my humble opinion. One of those headstrong my way or highway types ;-)
I never use my noise blinkers. I'm still interested in learning why when a noise blanker is engaged splatter/splash will be more than when it's not engaged? 73
There are many CB radio operators and I'm sure ham radio operators who overcompensate for some sort of shortcoming that they unfortunately have. At one time there were hundreds of them. The "I've got the biggest amplifier, highest, greatest antenna ever built, and I could splash all 40 channels."
I recall back during the CB craze so many operators believing the more channels they splashed, the better there stations were operating etc etc etc. It's sad but there are people who still actually believe that Splash equates to having a very powerful station setup. And even worse a station that properly set up. They truly believe this!
A noise blanker or limiter chops off the noise oeaks. Doing that to a strong signal will produce lots of distortion and splatter in the rx even when the tx sounds fine.
Very interesting. Fortunately there's only one local who splashes me ever so slightly one channel up or one channel below the one in which he is on. I am going to activate the noise blinker on my Madison next time I here him. He operates what I believe to be a stock unmodified Bearcat 980. I'm fairly positive the slight splatter/splash I received from him is due to his close proximity. Although he does use an amplifier. I don't know what type of amp but I'm assuming it's an 11-meter CB amplifier, and if it's not his close proximity that causes the splash it's probably the fact that he's using a dirty CB amplifier (are there any clean ones). Surprisingly the Uniden Madison has very good Channel rejection. I'm assuming it's a receivers Channel rejection that Handel's splash. (?) Unfortunately the NB on my Sonar doesn't work but the rejection from the same station both one channel up and one down it is even better even better than the Madison. 73 PS. I'm not knocking him or anyone for using a CB amp. I use two of them myself. One for my AM radio and the other for my SSB rig.
A lot of them can be clean if the operator is realistic about the wattage it should do.
Overdrive increases IMD which makes the signal wider (splatter) and there's not a filter you can buy to fix that. Even a bona fied HF amplifier will splatter.
Most of these old school guys could throw away the trashy little driver they call a modulator and really improve their station.
