All Multi-Standard radios have a selection menu where you can pick the country you are in from a list - UK for example, and when selected will give you access to all the CB channels and modes that are allowed in that country
You'll normally reach this menu by using a 'secret' sequence (switch the unit on with the XX button pressed in, etc), each manufacturer is different in how they do it, and it's not really a secret - how to do it is detailed in the instruction manual supplied with every CB!
Once you've made your selection (and 'locked' it in, again read the instruction book for this) the radio will always switch on using the allocation you selected, so you don't need to set it up every time you switch on.
The legal CB system in the UK is now slightly confusing with the recent (2014) legalisation of AM & SSB on the european band, but the bits you'll need to know are :
- We have 2 bands of 40 channels, making 80 separate channels that are legal
- Most new CB's will arrive set on the European band, so they can be shipped as-is throughout Europe ... the first thing you should do is switch it over to the UK band (on the UK allocation) - see the instruction book for info
- The UK Band can be used on FM only, the European Band (EC/EU on same CB's) can be used on FM, AM USB and LSB (the last two are often referred to collectively as SSB)
- Most CB's currently available were designed before the recent change to legalise AM and SSB on the European band, in the UK, so if you want to use AM on the European band in the UK, you have to set the radio to another countries allocation, where AM is allowed
For more info on the differences between these 2 bands, visit our UK and EU bands compared page
For more info on the newly legalised modes, AM, LSB and USB (much greater range than FM), visit our Get 30 mile range with SSB page
At present (May 2016) every CB that we sell is Multi Standard... but nearly all of them need to be set to another country's allocation in order to operate on AM on the European band, as described above ... again, see your CB's instruction manual to find an allocation where AM at 4w is allowed (usually setting it to 'Italy' is a good bet)
