FREEBANDING FREQUENCY CHARTS

There are two charts shown on this page:

1) Shows how the channels on a multi-mode CB can be converted to the UK CB channels.

2) Shows all the channels and frequencies that will be available on multi-mode CB radios.


Superstar 3900 (2009 model)
Above: the popular Superstar 3900 multimode CB radio covering AM, FM & SSB


Multi-mode, multi band CB radios have more bands than the usual two standard bands ( UK & CEPT ) that are included on the majority of normal new CB rigs that are on the market. Some multi-mode radios do not have a frequency read-out that shows the operator what frequency is in use. In these cases a chart that shows what frequency is allocated to each channel on each band is a necessity.

Two such a charts are shown below.

Multi-mode rigs will often have between four and eight bands selected by a switch or switches. For example a rotary band selector switch may be marked  A, B, C, D indicating four bands. Or there may be twelve bands in two banks of six. Each bank of six bands would be selected by a second 'hi / lo' switch. The rotary switch, in this case, might be marked G/A, H/B, I/C,J/ D, K/E, L/F.

To use the charts below it is first necessary to determine which bank / band represents the "Mid Band" "Mid Block" (which is the CEPT / EU band in Europe and the standard CB band in the USA) and then, working either side of the mid-band, it will be possible to see which channel and frequency applies to any given setting. The first chart shown shows the channels used on the UK CB band, and how they relate to the channels on a multi-mode transceiver. The High Band is the next band above the Mid Band and the High-High Band is one further step up. For example Mid Band is position G on the Superstar SS-158EDX, but other radios will differ.

Important: It must be noted that the UK and New Zealand use non standard and unusual channel spacing which do not fit in with this plan. To use the UK and New Zealand bands on multi-mode rigs will take a little careful adjustment of the clarifier control in order to get on to the correct frequency!

Example: When wishing to select UK Channel 25 on a multi-mode rig: Channel 39 on the High Band would be selected which would give a frequency of  27.845 MHz , however the frequency of UK CB Channel 25 is 27.84125 MHz. The frequency must therefore be reduced using the Clarifier otherwise reception will be distorted and the transmission to other CB'ers will be off-frequency and also very distorted.

If you only want to use FM in the standard UK or New Zealand FM bands it may be better to purchase a standard CB rig, channelised for the UK or New Zealand, rather than a multi-mode rig.
