Please be aware that posts do not always appear immediately, so clicking "Post your comment" more than once will result in duplicate posts.
If you are going by the lists above, I'm afraid some are out of date as the site owner has not had time to do all the updates after the 700MHz Clearance program. If you are receiving ITV, Ch4 and Ch5 etc then you should also be getting S4C as they are on the same multiplex (D3&4) in Wales.
See Channel listings for Industry Professionals | Freeview for which channels are carried on which multiplexes.
Please note this transmitter is a Relay Freeview "Light" transmitter and only transmits the 3 PSB multiplexes - BBCA, D3&4, BBCB HD.
