David: Have you noticed any degradation at all in the / for the main HD (BBC B mux) - BBC, ITV etc? This is on from .
Sky News etc is on the Arq A (Com5) mux on . If you are also seeing some degradation of those HD channels, then I'd start suspecting some issues with damp/water in the connections or the coax which will start affecting the higher channels first.

David, there is an outside chance you are seeing co-channel from the transmitter, which reuses UHF 52 and 56, the ones you are having problems with. The transmitter is more or less behind from your location though much more distant. You may be able to confirm this by getting your equipment into a portable state and testing it from a location where Huntshaw Cross is not in the frame to see if it behaves the same. Neighbours are likely to be suffering the same issue.

GEM: As I mentioned in my post replying to Nick Anderson, high atmospheric pressure can indeed affect television (DTT OR '') television and if everything such as your (type & condition), aerial alignment, aerial (type and length) and connectors have all been checked, and you have also carried out a 'first time installation' retune recently, then you have done all you can, and you simply have to wait until the weather changes and you have low atmospheric pressure again. If you are using the , make sure you are using a group E or a aerial, horizontally polarised.Also check whether there are many 4G phone masts close to your location. If there are you may need a 4G filter. You can get them free via the at800 website. the info I've provided here will you. Richard, Norwich, 2nd June 2016.

Martin B: Hi Martin B. There are no faults or work taking place at the at the moment and CITV is currently transmitting, "The Dawn of Morphos (Part 2), which looks very exciting! You could watch it live on the itv hub instead of getting it from . Your Freeview may be marred due to high atmospheric pressure, which is dominant across southern UK at present! this helps, Richard, Norwich, 11:05 on Thursday 2nd June 2016.
