You should be getting perfect reception from Sudbury at your location. I'd advise first check all your aerial/cable connections - unplug coax plugs/sockets, check and reconnect. Make sure that the aerial doesn't appear to have moved in any recent wind. Then do a Reset/retune with the aerial unplugged to clear all existing tuning and then reconnect the aerial and retune again.

Looking at the Digital UK Coverage Checker at Coverage Checker - Detailed View for your location suggests that the signals from Sudbury are fine except for those on the SDN multiplex, which is shown to be marginal. The listing also shows that reception from Sandy Heath is possibly better giving expected good reception of six multiplexes, but not for COM7 nor COM8.
You need to have a wideband aerial fitted, there is no such thing as a'digital' aerial. If you do not have satellite or cable services, then contact Freeview Suppoert at Important changes to Freeview TV signals | Freeview You may qualify for a free replacement of your aerial.

I think MikeP may have got a little mixed up with his reception from Sandy Heath vs Sudbury. Predicted coverage from the other possible transmitter (Sandy Heath) is marginal for all muxes except COMs 7&8 for which there is no predicted coverage. COMs 7&8 are not transmitted from Sudbury though.
The predicted coverage of the 6 main muxes from Sudbury is Good, but SDN/Com4 & ArqA/COM5 the two muxes carrying the channels you mention are not as good as the others.
I would check all your coax connections again and that the aerial hasn't moved then reset/retune in the manner as mentioned in my reply to Terry Wootten immediately before your post but check you are tuned to the correct UHF channels for the Sudbury muxes ie. - 44, 41, 47, 29, 31, 37. If your reception difficulties have been since the last retune event, then it's possible you may not have an adequate/correct aerial for which help may be available as mentioned by MikeP.

I'm not mixed up at all, just look at the ecpected reception shown on the Digital UK Coverage Checker for Tracy's post code.

I think Chris is correct . The checker shows that Tracy should get a strong signal from Sudbury on all channels . However Tacolneston and Sandy Heath transmitters are also in range though weaker signal. Its possible that Tracys aerial is pointing at the wrong transmitter .
I think I would check that the aerial is pointing at Sudbury . And manually tune the channels. Auto tuning may pick up the wrong transmitter. Use the channel numbers Chris mentions .

When I look at the coverage checker set to Tracy's post code it shows that only Sandy Heath has a good reception at her location, all the others have varying degrees of poor reception or none at all.
So I am correct. The only issue is whether she would gat the regional programmes she prefers.

Tracy et al:
Having had yet another look at the Digital UK Coverage checker set for the post code given, Sudbury is shiown as variable for SDN reception, Tacolnston is poor for the main 6 multiplexes but may be usable for COM7 and COM8. Sandy heath is good for the sic main multiplexes but not for COM7 or COM8, none of the other transmitters mentioned are of much value.
So is Tracy wants all the six main multiplexes then she should be using Sandy Heath, but if she is willing to have variable reception of SDN then Sudbury is an alternative though less than ideal.
Her location in Thurston End, Hawkedon, Bury St. Edmunds, IP29 4LQ does not appear to be ideal for reception of all channels at present. The alternative is to use Freesat instead.

Tracy & MikeP:
I'm afraid I still think Sudbury is your best transmitter and Hardy agree. I'm not sure how Mike gets variable reception for SDN (I still think he has his comments for Sudbury & Sandy Heath interchanged). Reception should be Good for all 6 muxes from Sudbury.
Make sure you are tuned to the UHF channels for the Sudbury muxes ie. - 44, 41, 47, 29, 31, 37
The channels you mentioned are on different multiplexes (muxes) ArqA, SDN, D3&4 & SDN in the prder you mentioned. So apart from carrying out the checks I mentioned in my previous post, look at your aerial to make sure it's still pointing in the correct direction.
