CB frequency allocations

Postby lars » Thu Feb 02, 2017 1:32 pm

Hi folks

I'm sorry if this question has been asked before -- there is some stuff on this forum that seems related, but I can't make sense of it.

My new CB radio has various band settings, including "UK", "EU", and "CE". I'm guessing the last is CEPT, but I'm not sure. It also has an AM-FM switch. I'm trying to work out what to set it to, to communicate with a bunch of people who bought their CBs from car boot sales, etc. When I asked whether we should be using UK or CEPT frequencies, I just got blank looks. The most technical response I got was "um... think it's FM. Not sure, really." I don't think anybody else even realized that there is more than one kind of CB radio standard.

Now, I've been told that CB radios are supposed to carry markings indicating the standard they conform to: CB27/81, PR27/GB, etc. My question is: is there a chart or table somewhere, that indicates what actual channel frequencies and modulation types these markings correspond to?

Thanks,
Lars

This is not all the channels but you'll get the point:

26.965 NFM :1 CEPT CB
26.995 not CB
27.045 not CB
27.095 not CB
27.125 NFM :14 CEPT CB
27.145 not CB
27.185 NFM :19 CEPT CB
27.195 not CB
27.225 NFM :22 CEPT CB
27.235 NFM :24 CEPT CB
27.245 NFM :25 CEPT CB
27.255 NFM :23 CEPT CB
27.265 NFM :26 CEPT CB
27.405 NFM :40 CEPT CB
27.6 NFM ████ UK CB (contiguous channels) ████
27.60125 NFM :1 CB
27.73125 NFM :14 CB
27.78125 NFM :19 CB
27.99125 NFM :40 CB

Original US CB is AM.
I thought EU and CEPT was the same thing and is FM.
UK is FM.
I reserve the right to ignore people who have made no attempt to the read the manual, and expect others to do it for them.

You don't say what radio it is, my Midland 42 Multi has several bands, I've listed them from the manual below, it doesn't mention the frequencies though, hope it helps. I usually use UK as it gives the 80 UK legal channels, although as we can now use AM as well I have used EU as well.

I Italy 40CH AM/FM 4Watt
I2 Italy 34CH AM/FM 4Watt
D Germany 80CH FM 4Watt / 12CH AM 1Watt
D2 Germany 40CH FM 4Watt / 12Ch AM 1Watt
D3 Germany 80CH FM 4Watt / 40CH AM 1Watt
D4 Germany 80CH FM 4Watt / 40CH AM 4Watt
EU Europe 40CH FM 4Watt / 40CH AM 1Watt
EC CEPT 40CH FM 4Watt
E Spain 40CH AM/FM 4Watt
F France 40CH FM 4Watt / 40CH AM 1Watt
PL Poland 40CH AM/FM 4Watt
UK England 40CH FM 4Watt English frequencies
+ EC 40CH FM 4Watt CEPT frequencies

Thanks. I have a Thunderpole T-1000, which is a fairly rudimentary, inexpensive radio. I didn't want to spend any more money unless

1. I was sure it was going to work in my truck and
2. I could communicate with other people

I'm still not sure about (1), and I didn't have much success with (2) when I last tried.

My radio has essentially the same bands as yours, labelled "EU", "UK", "D", etc. The manual doesn't say what actual frequnencies, or even range of frequencies, these correspond to. It just says the number of channels, as yours does. Rather oddly, the manufacturer were unable to say, either.

My real problem is trying to find settings that work with a CB that is labeled as conforming to "CB27/81", or "PR27/GB".

For general UK use, what do you set yours to?

Thanks,
Lars

Hi Lars,

I use a CRT one N CB radio, I have found that the UK 40 are the most active as there are plenty of old sets still laying about. I also monitor DE 80 as they cover 40 Channels of CEPT as well as an extra block of 40 on AM and FM. However nothing heard on them where I am; perhaps when the QRM whips up that will change.

look here for the complete block listings of CB frequencies.

I found this useful. :walkietalkie:

Sorry for taking so long to reply, my radio is set to UK because that's what seems most useful.

Not that it gets used much, just sits on the shelf gathering dust!
