Hi @acecarver
Which Freeview transmitter do you think you should be receiving your channels from ?
if i plug the ariel directly into my sony tele and select TV instead of extension d- HDMI, all i get is snow on the screen and a number 11 in top right corner, i've looked for a channel tuning icon but there isn't one. TV is over 10 years old.
the transmitter is at bruhsford, somerset
about 1/2 mile away as crow flies
That sounds like analogue tuning. Does your TV do digital at all? Try a full retune and see what you get.
an alternative approach
if your broadband is fast enough (22Mb or more) then as your Freeview transmitter seems to be one of the Freeview Lite ones with a reduced number of channels then talking to BT and switching to the Box Pro and using it in IP mode should give you more free to air channels (than Freeview Lite),
