UK Wireless law

[Anz]

Does anyone know the law on using a low powered wireless device (i.e a wireless microphone) in the UK? The only information i have on the mic I want to buy is 'DIRECTIVITY UNIDIRECTIONAL FREQUENCY RESPONCE 100 TO 10,000HZ OUTPUT IMPEDENCE 600 ohm +/- 30%' This doens't mean anything to me. If I was buying out of a catalogue/internet site, should it state that you need a license?

Don't know how up to date this is: http://www.livesystems.co.uk/radio-mic-licensing.h
tml but beware - some websites have (in the past) sold RF transmitters that can affect emergency service frequencies, without any warning that they were illegal to use!!!

The figures given are the cardoid response pattern of the mic capsule itself and nothing to do with the transmitter/reciever part.....If your buying from a reputable manufacturer (ie Shure, AKG, Beyer Dynamic or Sennheiser) then you should be ok esp. if it's new kit....you should look for the transmitter frequency of somewhere in the region of 175.000 Mhz (+/- 10 Mhz) and this will be ok.

Make sure the microphone is "CE" marked - this means it conforms to the ETSI standards for short range devices and does not need licencing in the UK (or Europe). Incidentally, the higher frequency (400M) devices are better than the older 175MHz devices.
