Now onto our continuing story.......

[N9ZHW]

I know I'm probably going to get chewed on again, but I just couldn't resist asking this too:
So, now, finally getting the information I need for turning this 4 watt CB into a massive RF power output machine capable of steamrolling down every TV set in the neighboring State of Illinois (how's THAT for dramatics?)    How does one weld extra channels in this thing? (I believe the ones I was told about were -1 [not sure how farbelow in frequency], 3-1/2, 11-1/2, 19-1/2, and 40+ -not sure if I forgot any...it's been awhile).
I'M ONLY KIDDING GUYS!! (Hey, even for me that's going over the line!) Seriously though,  I *have* known people who've done that. Is there any point in it? The excuse I was always given by people who've done that is "to get away from people and have some privacy and not get stepped on". Isn't that dangerous though? Can't you end up interfering with police or plane transmission I've heard because of secondary harmonics on "half channels" (so everyone called them) between 3 & 4, 11 & 12, and 19 & 20?

As you've probably heard before, there are many good ways of attracting attention on a web forum...

Trolling isn't one of them.

[N9ZHW]

I would NOT call it trolling.
Some people are just WAAAAAAAY too serious. I WAS actually in the midst of my having fun there, wondering if what I heard is true about the people I know that actually DO have those "in between frequencies" in their radios possibly ending up interfering with police or planes/control towers because of secondary harmonics? (If it's true THIS is the kind of behavior Charlie would be quick to take action on rather than some "guy down the street" if you will, having a 5 watt CB.) I'm curious if I should tells those guys about that if it IS in fact true it can happen.

I've got a Lincoln PowerMIG 300 that would do the job.

Police, Fire, and Aircraft have NOT carefully selected their frequencies in order to avoid harmonics of CB radio. The radio should not transmit any harmonics strong enough to cause interferrence. If it does you will get a knock on the door regardless of whether you are operating in between channels or not.

Now it is quite possible that unqualified people making modifications to any radio could cause it to create interferrence to other services (it doesn't need to be a harmonic issue).

Cute.    Well, maybe there ARE a few people out here able to throw a bit of humor in things once in awhile rather than be policing constantly.

Okay, I'll reach out and be the nice guy this trip. And also assume, because I can read between the lines, that you were being sarcastic towards the, shall we say, shallow end of the radio hobby "gene pool". Though from what I've heard through the years on Amateur Radio that may be reversed at times.

Onto the topic at hand; I've worked in more than my share of tech shops, and had/have a couple, and have had the distinct pleasure of repairing many CB radios after some other, er, technician fixed them. Now that my digs at the aforementioned community are complete and you are aware that my knowledge is not hearsay and rumor I can pass on the information you seek. The in between "channels" you ask about are are not "guard channels" to prevent interference. They were, and still are one-way non-voice Subpart C (Class C) Part 95 remote control frequencies. Though all of the "high value" RC plane, boat and car pilots/drivers have long vacated these frequencies for 72-76 Mhz, you can still find the cheap RC toys, wireless keyboards/mice, etc. here. Once upon a time you could also find Page-Alert car alarms here, too. As a matter of fact, back in the '70s and early '80s it was not uncommon to hear the splatter of a malfunctioning Page-Alert roaming around town jamming CB Chs 11 and 12. They were also the source of many mysteriously dead automotive batteries for the same reason, the customer, just as intellectually challenged as the CBer he was unwittingly jamming, could not comprehend the simple instructions shipped with the alarm. On the down side, instead of CBers getting jammed, we are awakened at all hours every time there is a backfire (or gunshot in most modern neighborhoods) or sonic booms that set off car alarms because the equally stupid owner set the sensitivity too high.

But I digress; There is also more to the Class C enigma. CB Ch 23 is a shared RC/voice frequency, 25 watts and obviously 4 watts respectively. Finally, why the gap between 22 and 23? Rumor has it that during the the 23 Ch era before 27.235 and .245 were Chs 24 and 25 they were used as guard channels between the 25 watt Ch 23 RC channel and the lower 5 watt input channels. This was not spelled out in Part 95, but it's quite obvious. Finally, the space between 22 and 23 was 25 watt business band frequencies, as well as above 23, before they were handed (surrendered?) to Class D.

So there you go, all of, or more than you care about, obscure 11M trivia that I'm aware of. And trust me, it is knowledge I
could easily live without.

10-4 guh buddy ur turn.

You lost me on half of this.    *shakes head in confusion*

Well there's a big surprise. You can actually learn something here if you're not too busy trying to be funny.

[W5FYI]

Why not visit www.eCB.net with this kind of stuff? Eham, I thought, was for ham radio topics...?

Hey, what do you mean "trying"??

I thought it was RADIO topics.....? Not enough wisdom many times on the CB ones.

This post is better suited for a CB radio forum.  I think that's what people are trying to get across to you with little success.   In the upper left hand corner of my screen it says "eHam.net, ham radio on the net".  Nothing about CB in there that I can see.

OK, let us explore the practical side,a 4 watt radio, carrier 2W modulated to 100 % peaks would be 4  watts clean output. Now tune it up to 7 watts, does the radio have a 14 W audio amp? probably not. Turn up the mic gain and splatter.
 The folk lore I heard about the in between channels, referred to as A channels were designated for the RC  channels.
I believe the best answer so far is from N3OX the welder. But didn't Binsford manufacture a radio that would fit the bill.  Suggest you get a hold of Tim Taylor for the specifics. Currently using the call sign KA0XTT.
