I have been told that BBC4 is now on channel 803 on Freeview, but get a No Signal when I use that channel. Any suggestions as to how I can get my favourite TV channel?

John Dennis: BBC Four is, and has always been, on logical channel 9.

BBC Four HD is on channel 106, if you can receive it.

Hi, Re Mendip:
I'm still not getting BBC4 HD on channel 106 in central Weston super Mare
despite retuning, and performing 'first install' ?

Please advise.

David Newton: As you specifically mention BBC4 HD on 106, are you meaning that 106 is missing from the EPG listings? or is it the case that 106 is seen but selecting same results in a blank screen.

Are receiving the other HD channels on COM7 OK, e.g: 107-108-109 etc, if not carry out a manual tune on Mux Ch33 / 570Mhz.

By the way, its assumed you are aware that BBC4 HD only operates from 1900 - 0530 hours?

Hi, thanks for fast response.

Confirming 106 is missing from EPG listing on every HD device in home.
No channels exist between 105 ->120
As suggested, tried checking Ch 33 on the main Living room TV.
Setup reports "NO SIGNAL - Signal stength/quality 0%"
Reception strength for all existing channels is good.

Do we suspect the old aerial is the culprit ?

David Newton : If the problem is evident on all of your HD devices (if "not" all of the same brand) then this does rather suggest that COM7 / Mux33 is not being received, and although your precise location (post code) is not known, a test carried out using the railway station as a reference point indicates reception of COM7 is possible in that particular area.

Although you have already carried out a manual test on Mux Ch33, I would like you to try it again on more than one device, as on many brands (but not all) if search or scan is "not" pressed after having entered the Mux channel number required, then if any signal is being received, no matter how low it might be, the level of will be seen on the strength / quality bar.

If this still results in zero signal being received then try Mux Ch31, this being Wenvoe's COM7 which you might be able to receive on the reverse side of your aerial "if" anywhere near to the test code used, as Wenvoe has a slighter better line-of-sight using the test code location over that from Mendip.

The only reason for requesting this check being, that in cases where a "genuine" zero signal is received from a particular transmitter, changing the aerial does not usually make any difference to the situation.
