CB Radio

[That Ruddy Squirrel]

I now also have a handheld, but beginning to think I may have got the "betamax" cb

Yep my handheld is on the 27/81 set of frequencies and I cannot hear anyone out there - can anyone confirm that that frequency range is compatible with the latest set ?

CB questions:

What are the laws/regulations regarding using CBs while driving?
Is it the same as using a mobile phone?
Is this a grey area?
Is it a loophole that just hasn't been plugged yet?

Any comments on the 27/81 issue I mentioned above ?

Hi Trev,

I am not sure about the marking on your CB, mine has 27/94 on it, but I live in leicester and I was very lucky to find someone around for a rig check, so I don't think that there are many using CB anymore (thank god), so you might be fine, just no one out there where you are...

MPT 1382 (December 1997) has been revised to permit any combination of the existing 40 UK channels (MPT 1382) and the 40 CEPT channels (ETS 300 135). This allows for up to a maximum of 80 channels within one set. Equipment based on this revised specification will be strictly for use in the UK only.

I have just fitted a PMR in my spare din. It looks better than a CB and the mag-mount antennas are much smaller too. PMR's are going cheap on ebay!

Whats a PMR and how does it differ from a cb

[joker??]

i think it stands for personal mobile radio (walkie talkies)

CBs are not classed the same as mobiles. http://www.4x4cb.com/public/showpage....cfm?CatID=653

Trev.

This might help you, looks like it should work, but not as good as the new ones.

Way Cool, well I will be on the air and belting (chugging) up the M1, M6, M56 tomorrow, now if my massive mag mount and aerial don't dissapear off the roof, I'll be looking out for any surfers

PMR Stands for Public/Personal/Private Mobile Radio

Most "walkie talkies" that you can buy that are not toys work on the PMR band. I purchased an ex gas Private Mobile Radio base station that with a computer can take direct frequency input. You just put the frequencies in that are listed below and off you go.

From the net:
PMR446 is a European standard licence-free radio service utilising 8 12.5khz spaced channels in the 446mhz band.

Due to the considerable uptake of the service, PMR446 radio sets can now be bought from as little as £20 (about 30 Euros) a pair. The Radio Agency requires that radios have a maximum of 500mw (1/2 watt) ERP (Effective Radiated Power) to an internal antenna. This limites range to, realistically 1/2 to 1 mile around town and up to 2 miles in open country. In line of sight conditions and at altitude ranges of over a hundred miles have been obtained.

CTSS (continuous tone squelch system) is incorporated in most radio sets as a means to prevent interference with o$nly 8 channels available - the radio ignores all incoming signals except those that are also transmitting this sub-audible tone.

There are eight 12.5 kHz simplex frequencies which can be used anywhere in the United Kingdom. The frequencies have been harmonised (but not necessarily authorised) for use across Europe. The channels centre frequencies are as follows:

1. 446.00625 MHz
2. 446.01875 MHz
3. 446.03125 MHz
4. 446.04375 MHz
5. 446.05625 MHz
6. 446.06875 MHz
7. 446.08125 MHz
8. 446.09375 MHz

The frequencies are shared and users may, under local heavy use conditions, experience interference and problems with sharing channels. These may be reduced by changing frequency and/or CTCSS tone and/or DCS code. PMR 446 is not suitable for safety of life use or for users who need to have access to frequencies at particular locations and times.

As a licence exempt service, PMR 446 is unprotected and the Agency will not become involved in interference or channel sharing disputes between users.

Before speaking you should check that a frequency is free by either listening or using the channel busy indicator. When you speak you should identify yourself and the person you are calling. The radios allow communication in o$nly o$ne direction at a time so you will find it helpful to identify when you have finished speaking. It is expected that the frequencies will become particularly busy in cities or where large numbers of people gather such as large sporting events. All users will benefit if messages are kept short.

PMR 446 radio equipment can be used in CEPT member countries that have implemented the ERC Decisions listed above.

Before using PMR 446 radios outside the United Kingdom, users should check that the relevant administration has implemented the Decisions. Users who fail to do this and use their radios overseas, may break the laws of the country concerned, run the risk of prosecution and the confiscation of equipment.

Details of the progress made by CEPT member countries in implementing PMR 446 can be obtained from the European Radiocommunications Office (ERO) website http://www.ero.dk
