ham to cb

[wweinaug]

Is there a way, or radio that can talk to cb and ham? and can say a 2m talk to a 10m?



Thanks,
William

I don't know of any.

2M and 10M are two different frequency ranges... so short of some sort of trans-band repeater.

There are HAM units that have the capability to transmit on the CB frequencies... but it is not legal as they are transmitting well over the wattage allowed by the band plan.

First off 2m and 10m are both ham radio frequencies.

Second define CB radio, IN the US CB consist of 4 separate and unique services. 3 are license free 1 requires a license.
11m Citizen band, your 40 channel radio most people think of in the US when you say CB. 10-4 good buddy, trukers and all.
There is also MURS (Multi use radio service). 5 channel VHF service.
FRS (Family radio service) 14 channel low powered UHF radios. 7 channels
shared with GMRS.

GMRS (General Mobile radio service) 15 channel UHF service, license required.


All have specific radio certifications and with the exception of FRS/GMRS they are not permitted to be linked to other services.

SO No you can talk from ham to CB.


In the UK
CB is a FM service on 11m band and there is a FRS like service called PMR.

In Oz
CB is a UHF service

Other countries have FRS like services often on UHF.

Nicely done!

There is no law against a Ham radio being able to xmit in 11m CB AM/SSB modes, but as a Ham you can not legally xmit there. (edit: Kurt already stated that )

However, it is illegal to posess an 11m CB that can talk to any other service. Thus you can't even within the written law have a radio with both CB and FRS combined.

``The speed limit is also 55mph.''

pskatt.
You're killing me. Would you be implying that you can mod a 2m radio to transmit on CB frequncies?!?!?!

Australia has 11m CB, it's the same 40 channel allocation as in the USA.

Actually, I think it would be illegal, Scott. A radio must be type approved and a CB would fall under Part 95, while ham radios are covered by Part 97. You could have a FRS, CB or GMRS radio combined, but without having both Parts 95 and 97 approvals, I'd think a modified ham radio for CB would be technically illegal.

Not totally true, While the is no FCC rules, there are DOT rules for truckers. Also while you ham radio can but open to transmit on 11m you cant legally transmit there and the FCC will site intent. A ham with a radio open for 11m isnt going to be busted but if you dont have a ham license and have an 11m opened ham radio you can be busted for an illegal radio.

Not true, I can legally have a CB that can be used on 10m or 12 or 17m, Its just can never be used on CB again. As for CB and FRS, there is no law that says you couldn't have one, there BOTH in the same license class. It would make more sense to have a CB/FRS than a GMRS/FRS. It would be hard to make the FRS be overly usable since you cant have a detached antenna, but it legally could be done.

Gary, I'm pretty sure a CB/FRS is not a legal possibility. I'm reading through the CFRs now...

As a Ham, I can build my own radio. I could modify an existing radio for transmission and reception on Ham-allocated frequencies. Because said radio(s) may have the capability of transmission on other frequencies does not make my use of it illegal, as long as I legally stay on my allocated freq's.

As a Ham, I guess you could but you obviously wouldn't due in part to the whole VHF vs HF / AM vs FM and required components etc, and more importantly that one legally can not use a non-type radio in the Citizen's Band Service.

My 55mph statement was simply that I'm interpreting laws IANAL and I'm perfectly aware that a lot of people break them all the time, especially the freebanders, and those with 11m `linears.'

Oh, gotcha. Yeah, I could see that a modified CB would be fine for us on ham bands. Then, like you said, once you modified it for 10m or 12m, it would then be illegal as a CB forever. I still think it would be illegal to use a Part 97 radio on Part 95, i.e. a 10m ham radio for CB.

Edited to add a thought: Wasn't the question could you buy a CB/ham radio? That I think would be impossible unless a manufacturer got both Parts 95 and 97 approval. But like you said, Scott, the original idea of ham was to tinker with radios and modifying them is intrinsic to the principle of amateur radio. This is why most repeaters are salvaged commercial gear. Once modified for a ham repeater, it can stay a ham repeater but could never be put back into commercial service, at least without going back through a tech and re-certification.

Whether or not it's in the code, it would certainly be a technical nightmare to meet the FRS requirements on CB. The fixed antenna, 0.5W max ERP, etc. But I think if you wanted to, I'd bet legally you could make a combo radio.
