paul marsh: I think that it's not very likely that you will be able to receive from Winter Hill even though it is only 5.5 miles away.
Have a look around and see if anyone has a horizontally polarised aerial on Winter Hill. This (if there are any) might be a clue as to whether it might be possible. If there aren't any, then it might be because no one else has tried or it might be because it isn't possible.
Other than that, Freesat is probably your best option for additional free-to-air channels. There are some differences in the offerings of Freesat and full Freeview (ITV3 IS on Freesat):

Sarah: No. Unless you can receive from another transmitter that carries all channels, then you won't get any more Freeview channels.
BT Vision offers Sky Sports and these channels are broadcast over the air and only available from transmitters with the full range of Freeview channels.

A1batman: The COM channels do not have as wide a coverage as the PSBs. They are only carried on the largest transmitters and in some cases are at lower power, as is the case with The Wrekin.
Have you had your Group A aerial replaced with a wideband (or Group K) one?
How does the strength of PSB1 and PSB2 compare to COM4?
The sensitivity of a Group A aerial will drop off outside of the Group.
For aerial groups, see:
Aerials, TV Aerial and Digital Aerial
Some example gain (sensitivity) curves:

If you do have a Group A aerial (red tip) and am looking for information, either to be briefed when you get a professional in, or to do it yourself or get a friend who likes heights to do it, then see:
The Wrekin

Adrian Durrant: Yes they are ERPs.
According to Digital UK predictor and Ofcom's "Digital Switchover Transmitter Details", all of Hastings' six multiplexes are at 1kW:

However, the multiplex licences published by Ofcom, version 7 (27 January 2012) says that the PSBs are 1kW and the COMs are 0.5kW:

I understand that the information at the top of this page is sourced from the licences document.

Judy Evans: There is an issue with Goodmans GDB3 models whereby they will not receive post-switchover signals that have a negative offset on their UHF channel number. This is the subject of a Digital UK briefing:

There are a number of transmitters that you could be using in Brighton, depending on where you are.
Taking Whitehawk Hill, BBCA multiplex (which carries BBC standard definition services) is on UHF channel 60-, thus it has a negative offset. UHF channel 60 is at a frequency of 786.0MHz whereas 60- is a little bit lower, it being 785.8MHz. This is above C59.
This receiver cannot pick up post-switchover signals that have negative offsets on their channel numbers.
No other multiplexes have a negative offset from Whitehawk, so these would be expected to be receivable with this device.

Judy Evans: There are some unofficial firmware upgrades for some Vestel boxes and I'm not sure if one may be suitable for the GDB3.
The process requires connection of the box to a computer via a RS232 (serial) connection.

Fred Selley: You won't receive 4seven on Freeview as it is only available from transmitters that carry all Freeview channels.
I received the same message myself when I switched from BBC to Channel 4, so I can only assume that the message to retune is being broadcast over the air on Channel 4, hence everyone will see it, even if they cannot ever tune to it.
I think that the likely answer at your location is that you won't be able to receive full Freeview. Freesat provides additional channels, including 4seven.

molly: 4seven is available after switchover in areas that receive all Freeview channels.
If you are receiving from a transmitter that only carries the Public Service multiplexes, then you won't be able to receive 4seven on Freeview.

G. Elstob: 4seven is not available on Freeview areas that haven't switched. You will receive it when Pontop Pike switches in September.
