CB repeaters are not legal.

You'd have to ask those hams.

Since novice ops are dumped onto VHF, they might be complaining about new hams conducting them selves like they did on CB via a VHF repeater?

For me, I never worry about what CBers do unless they wind up on a ham band.

Since I don't listen to any repeaters, I don't worry about people who do use them.

I would "assume" (and we all know what happens when you do that) they're referring to using a simplex repeater. These are simple store-and-forward devices. Because CB users have no right to privacy and it's perfectly legal to record their transmissions, it would be legal to use a simplex repeater controller to record their transmission. Also, because there is no rule concerning a control operator being at the location of a transmitter, that an unmanned transmitter would not be illegal. Combining the two bits of reasoning, I can see where a simplex repeater would be legal to use on CB frequencies on a non-interference basis. This is based on my own logic, and of course, I have no legal basis for my opinion. The rules were written before such devices came into being. -WY3X

There are a number of FRS/GMRS repeater setups here in the NYC metro area and I believe they are legal. That may be what they were referring to.

I seriously doubt the average CB'er would take the time nor would it be advantageous to go thought all the trouble required including the idea of spending all the money that would be required to set up a repeater on that band.

It would be much easier for them to just get a ham license and operate VHF.

Quite frankly, even if they did, a repeater on CB would suck and it wouldn't function very well at all. It would be like putting a repeater on HF bands. It's a completely useless endeavor.

I guess it would be as good as a 10M repeater.

When I was in Australia (some years ago now) there were a few CB repeaters in operation.  The rules said that
CB radios couldn't transmit and receive on different frequencies on a single channel setting, so the repeaters
were set up to receive on, say, channel 1 and transmit on channel 40.  That gave maximum channel separation
but only required one click of the channel switch (presuming it didn't have a stop) to switch between them.
So everyone would listen on channel 40 then switch to channel 1 to transmit.  That would still require good
isolation between transmit and receive, so it wasn't something that the average CBer would set up, and there
were a limited number of channel combinations that were practical.

I have no idea whether such repeaters would be legal under the US rules, or even if they were legal under the
Australian rules at the time, but they could be used with unmodified CB radios.  I suspect that the simplex
repeaters are more common, but having tried one in another service they can be rather awkward to use.

There was a YouTube video of 11M repeaters in the Caribbean area a while back. CB'ers in the UK are messing around with internet linking on 27MHz and PMR 446, OFCOM seem to be condoning UHF linking and turning a blind eye to 11M linking. Seems like they are getting usefull info from it?!

Beat that !

The FCC's Class D Citizens Band (what most refer to ) does not have repeaters here in the US.  Other classes, such as Class A, do.  Other countries may have sevices that use the same frequencies and use repeaters... I do not know, and there is a lot of illegal activities, also.
Now we do have amateur 10 meter FM repeaters allowed above 29 Mhz.  I doubt that is what is being discussed, though.  You are probably hearing about the GMRS service here.
