we were led to believe that after digital switchover we would all receive the same service, nobody mentioned freeview light! clearly this was omitted for publicity reasons, when will this situation be rectified?

D Williams: Because sadly that is the way things are going these days.
"Public Service" and "Universal Service" tend to be allowed to give way to profit-driven organisations.
The Commercial broadcasters which don't transmit from Cynwyl Elfed and over 1,000 other similar small relays can choose where to site their transmitters.
Due to them operating to generate profit by selling advertising, their interest is to have as many potential viewers as possible at the lowest possible cost. They broadcast from 81 of the largest transmitter sites (largest by viewer population) and achieve coverage of 90% of the population.
For them to include all the other relays would roughly double their cost of transmission whilst only adding 8.5% of the population to their potential viewer base.
The "Freeview Light" transmitters carry only Public Service Broadcaster services. The Commercial broadcasters don't have a Public Service obligation.
The hilly areas that require relays to fill in the gaps are worst affected. Wales is particularly badly affected, with the Highlands of Scotland and the Lake District also being poorly served by the Commercial broadcasters.
