CB Radio Talk

Are there any 11 meter repeaters operating anywhere in USA?
If no, how come?
E.g., mebbe not legal per FCC?

You answered your own question, as per Part 95 subpart D rules, repeaters are not allowed, I guess they consider this rebroadcasting. The Citizen Band frequencies are for (lol) short communications, (no rule against skip anymore).

I am curious what frequencies you would request as a repeater pair set for CB?

With how CB is enforced here in the US, I doubt anyone would say anything as long as you didn't cause trouble for others outside the CB band. But then comes the question, if such a thing were set up, would it be worth it, and how many people would actually be able to use it?

Another thing to consider is that said repeaters would attract the biggest troublemakers on the band as well.

Considering that the furthest two frequencies on the CB band are 0.44 Mhz apart, while repeater pairs on the 2 meters ham bands are 0.6 MHz, which more space makes this easier to do I don't see this as necessarily being a problem today if anything it is just a matter of money, although the cavity filters said repeaters use would be noticeably bigger at CB frequencies. I also think that the FM used on 2 meter repeaters is better for repeater use than the AM used on CB. I am not sure about repeater use on other services, like FRS/GMRS.

Sorry about the ramblings, just a few thoughts on the matter.

“biggest troublemakers”

No doubt, when ever I stick the Abbree whip on my 75-822 and settle in on the sofa, often it’s spoiled by a couple folks yelling, chanting, singing idiotic BS.

I would bet that it stems more from the rule against automatic/remote operation on CB frequencies.

GMRS does have repeaters though.

but it would be beneficial to have ch. 9 (emergency use only)
many years ago i know police monitored ch 9

Perhaps there are groups around that follow said rules to the letter, however, there are enough people out there that ignore various parts of said rules that I highly doubt this rule is what is keeping people from setting up repeaters on the CB band. How many people run more than 4 watts. How many people used CB to make contacts further than 155 miles when that was banned. How many people have modified radios that are out of manufacturer specs. Ect. ect. ect. I'm sorry but with my experience with CB operators, I'm just not buying this as a reason that it hasn't happened.

Absolutely I could not agree with you more!
The technology is well known, and generally speaking ... if somebody wants to do something.... they are going to sidestep the rules no matter what. Since they don't manufacture repeaters for the 27 MHz portion of the spectrum one would have to create one out of a couple of radios and some "electronic glue" and a little luck to make it work.

All I was attempting to do was point out the existing FCC regulation that, more to the point, would have been put in place that would prevent using repeaters.

Allow me to rephrase.....

If one were to build an ad-hoc repeater system for the 27 MHz Citizens Radio Service and the FCC were to discover it's existence and chose to press the issue..... THIS is the regulation that will be quoted.

I have no argument with that line of thinking, but at the same time, as long as the repeater didn't cause problems for people outside the CB band, I highly doubt they would go looking for it.


The DB

Agreed!

As it seems to be the norm nowadays..... if you do it and nobody says anything..... enjoy!!!!!

Thank you Greg.
Given your 'FCC regs specific' reply, you have taken my thinking, now, to the next level....
Would this seem to you to be an FCC reg that would be, by law,
nullified by a government declared emergency,
as is the FCC regs that Ham licenses are not required for transmitting
during government declared emergency status conditions?
Apologies if the above is on the wordy side .... however, still working my way thru the 1st cup of joe.

My opinion of when the "SHTF", CB radios are more abundant then any other radio communication with ham radios coming in second. I wouldn't be the least bit worried about any kind of regulations then.

Greg,
Is this the section within 95 subpart D to which you are referring? -

["§95.933 Prohibited CBRS uses.
In addition to the prohibited uses set forth in §95.333, the operator of a CBRS station must not use a CBRS station:

(a) To transmit one-way communications other than those permitted in §95.931(b) (transmissions to seek to initiate two-way communications with another station are not considered to be one-way communications);"

Thanks - Rip.

All this thinking ....seems to me it would be easier to take a tech test and go 2m. Instead of reinventing the wheel. There are 2m repeaters just about everywhere. And more helpful people on the ham bands. At least in my area that is true.

Nosaj -
Your above view is well taken.
Clarification.....
My original post question is merely driven by CB related curiosity
not any actual intent or expectation of putting CB Repeaters up
(I lack the knowledge, $ and time to do so even if it were FCC sanctioned).
Meanwhile, one of the benefits to me of this string is Greg prompting me to the CB related FCC regs....
Previously I had read the Ham regs but not those pertaining to CB = thanks Greg.

The rules have been rewritten and now they are very vague (at least Part 95) as to their meaning but this one is close to what you want to know. If I remember correctly at one time it was illegal to relay a conversation on CB but everyone still did it. I saw you said you checked the Amateur Radio regulations on repeaters, 29mhz (FM) is the only band close, have one in my area but have never caught it on (yet).
