Clive Field: My understanding of the Humax HD machines is that when you manually tune, you need to specify the appropriate mode of the signal in question or else it won't find it.
So for HD it needs to be set to DVB-T2, rather than DVB-T which is the mode used for standard definition broadcasts.
I'm not familiar with them, but I should imagine that somewhere near to where you enter the UHF channel number you want to manually tune to, there will be a way of selecting DVB-T or DVB-T2.

G Thompson: It's clear that you do not wish to address the issues. You are fortunate in that you do not reside in a so-called "Freeview Light" area.
If the problem is that the local news you are getting on BBC One and ITV1 is wrong for the transmitter your aerial faces, then this may be an indication that it is tuned to a transmitter to which the aerial doesn't face. In your particular area there are a number of overlapping signals.
This was the case with analogue before switchover.
For example, your receiver could be tuned to Yorkshire from Belmont (in Lincolnshire) instead of Anglia from the King's Lynn relay transmitter (even though your aerial faces the latter).
If this is the case, I am not sure by reading your postings that you wish to get to the bottom of the problem and find a solution.

John: It's due to happen on 27th June when a retune will be necessary for all Commercial channels as they all change UHF channels.

Roger: Because there are a limited number of ITV1 HD regions. See:

Liam Boyle: This one isn't going to be easy.
Refer to the Digital UK Tradeview link beside your posting for the channel numbers used by Belmont and Sandy.
They are neighbouring or a few apart. In some cases a workaround is to unplug the aerial lead for part of the scan. E.g. if all the channels you want are in the 20s, and there are troublesome ones in the 40s, you could unplug the aerial at 30%.
If you can reduce the level of amplification then that might help as it will reduce the level of the unwanted signals and hopefully the Sandy signals will still be strong.
If you can, the answer may be to wipe what's stored and manually tune the five standard definition services (and one HD mux if applicable).

Marty: Bilsdale does not broadcast HD until switchover.
My guess is that either you are either picking it up from Pontop Pike which hasn't switched over yet, but is one of a handful of transmitters that has a pre-switchover HD signal.
To find out which you have, go to one of the HD programe channels and bring up the signal strength screen. If it says that it is tuned to C63, then it is coming from Pontop Pike. The other possibility is Emley Moor which is on C41.

Marty: Aerials pick up signals from other transmitters, usually to a lesser degree than the one they are intended for. How much (and if at all) you could say depends on luck.
Evidently your aerial is picking up a HD signal from somewhere, and as Bilsdale doesn't broadcast HD at the moment, your receiver has tuned to it. So don't be surprised if reception isn't perfect because an off-beam signal is being received.
Yes, Pontop Pike will continue broadcasting HD as it does now until switchover. As I say, HD isn't part of the standard offering before switchover. A handful of transmitters nationwide that operate (and operated) before switchover were selected to carry HD services and Pontop Pike was one of them. This does not affect Bilsdale's HD signals that will come on air at switchover in September.
So come 26th September you should be able to receive HD services from Bilsdale.

Matt: I wonder if it is interference from another transmitter that uses the same three channels (41, 44 and 47). Hemel Hempstead uses those channels and it switched last month (although its signals are vertical as opposed to Hannington's which are horizontal so that should help rejection to a degree).

Ted: You asked about switching your aerial to vertical. It depends on which transmitter you are using (with the exception of a few that transmit horizontally and vertically).
If you ask the question because everyone else's aerials are vertical, then they may be on a relay transmitter that doesn't carry the Commercial multiplexes.
