UK TV frequencies map - channel C55 (746.0MHz)

my installer was surprised to find his signal meter registering a strongest freeview signal from whitehawkhill (Brighton?) freeview when the antenna was probably pointing towards Huntshaw cross.My post code ex20 3nr and Im in a deep valley.
Abnormal propogation, faulty software or the Identity adopted by Huntshaw ?

Douglas Dwyer: You can't get a signal from Whitehawk Hill on the West side of Hove, so it's not going to be from there. Try seeing Find a freeview transmitter by frequency | ukfree.tv - independent digital television and switchover advice, since 2002 to find out a more likely mast.

Please help, I've completely lost MUX 2. I recently changed from a cheap STB to a PVR and everything was going well. Then the picture started pixelating a little so i bought a signal booster to see if that helped. Rescanned for channels only for all the channels on mux2 had not been found. Plugged in old STB and still mux2 is missing. No reported problems with transmitter. I'm pulling my hair out. All other mux's/channels are fantastic, even CH5 and CH34. (map)

My auto search will not fing channel 5, my post code is BS16 3XG (Bristol). Do you have
the frequency to enable manual channel search?

My reception is very good otherwise. (map)

David England: There is no difference at all between an automatic and manual search. Please see Single frequency interference | ukfree.tv - independent digital television and switchover advice, since 2002 for help. If you want to know the frequencies, find the transmitter you are using at Find out how to receive Freeview at postcode BS163XG | ukfree.tv - independent digital television and switchover advice, since 2002 for full details.

I retuned my Thomson PVR box on the Granada switchover (Winter Hill / FY4 3HE) on 2/12. It now receives the Welsh versions of BBC and ITV channels.

I changed my TV the day after (the other one's picture had gone funny rather than any other reason) and the built in Freeview won't pick up the Welsh channels even though I have done automatic and manual tunings.

Any reasons this may be the case ?
