Licence-free UK operation
The SDPRO system transmits on 863-865MHz within Channel 70, which is licence-exempt in the UK – no Ofcom licence is required to run events. The FM-modulated UHF system is unaffected by other wireless transmitters in the room, so radio mics and IEMs on other frequencies can run alongside it.
