UK Wireless Microphone Licence
UHF - (1 year or 2 year Licence)
Channel 38 is available on shared non protected basis from 606.500 - 613.500 MHz. Licensees may use any frequencies within this range.
Guard bands have been included at each end of channel 38 to avoid interference with future services in channel 37 and channel 39 and facilitate free-roaming use throughout the UK .
10 Channel plan
The UK Wireless Microphone Licence does not specify spot frequencies in channel 38 but the 10 channel plan below will ensure that all frequencies can operate in the same location without harmful interaction. This plan is a suggestion only. Users and manufacturers can devise their own plans that could involve any number of frequencies within the range.
|Channel 38 - 10 channel set ratings|
|2Tx IM(3) and 3Tx IM(3)|
In developing the plan we ensured that each frequency is safely spaced apart. However interaction can sometimes occur between frequencies even when appropriate spacing is applied. This unwanted interference can occur when equipment is operated close together in the same vicinity. It is known as intermodulation or “mixing”.
In the real world these unwanted signals appear on or close to the frequencies being used. To help make sense of this we have devised a figure of merit that we have called the “Risk Index”. This is calculated according to the quantity of unwanted signals and their spacing from the frequencies we are trying to use. Closer spacings have a higher risk of causing interference so are given a higher weighting in the sum.

Doesn't match up?
If your kit isn't tuned to the frequencies suggested you may still be able use it.
Check Your Frequencies to see if we can Licence it at the power, bandwidth and location you require.
If you use our recommended channels licensing should be quicker and we are more likely to meet your requirements. You will also be able to book online.
