on UK Free TVDue to the frequency conflicts the Hunshaw Cross and Mendip transmitters had at switchover, they have restrictions placed on the output levels of the SDN, ArqA and ArqB multiplexes.
From today, viewers will need to retune if they use the Mendip transmitter as the channel allocations for these multiplexes have changed frequency.
If you use Hunshaw Cross and did not receive the SDN, ArqA and ArqB transmitters at switchover at all, you will also need to retune, but a retune is not required if you have already all of the Freeview channels.
