In response to your suggestion jb38 I have access the manual tuning function and inspected ch28, the strength was very good, but the quality was ~10%, but i did not move our aerial. I suspect moving the aerial may well improve the quality.
As a side, I have now resolved the issue! I hope this will help others... The solution?
HDMI / Coax interference. In summary, I have moved our booster away from the other mains cables and the HDMI leads going in / out of the AV receiver. The HDMI leads have also been moved away from the coax aerial feed which when moved drastically improved the quality of ch47. I replaced the fairly cheap HDMI lead going from the PVR to the AVR with a spare I had (which appeared to be of a better quality, look and feel anyway) and the quality of ch47 shot up to 100%. All other channels are also 100%.
Now, why this affected just one frequency / channel, I have no idea, but the conclusion is that interference can occur between HDMI and Coax circuits. I have done a small amount of digging on line and others have reported similar issues including interference from games consoles vs certain freeview channels or their entire reception. So, in my case it would appear a better quality HDMI lead from the PVR to AVR helped reduce the interference. I hope this makes sense, and I hope it will help others. Thaanks for taking the time to reply jb38.

Paul Nickson - check your cables, HDMI and coax in particular. See my post above.

No problem. We have tried using Rowridge in the past with little success. The terrain maps offered by this site indicate that the signal is pretty much a no go and the official digital tv sites all suggest Hannington as a priority. I am happy to try other channel tests using our aerial where it is if that help you jb38. Our location here in Southampton is also half way up a hill which is almost the tallest point in the city.
The time of day weirdness surrounding the quality of ch47 is indeed very odd. There was a notable difference in the morning vs the evening. The only difference that was obvious was the temperature outside and in our loft and surrounding our equipment. The lounge is much warmer in the afternoon with the sun beating in.
One other thing to note, we are on the flight path for the airport, but this has never caused any issues with the signal in the 7 years we have lived here.

Southampton
We live in Southampton SO18 2QF which is a no go for the IoW transmitter, therefore Hannington has always delivered the goods. Recently (over the past few weeks) all channels which are part of ARQB (channel 47) are extremely low quality and sometimes non existent. The signal strength according to our PVR is 10/10, but the quality is very low with errors reported. All other channels are 10/10 in strength and quality. I have noticed the problem is at it's worst on a sunny afternoon. We are using a loft aerial which I purchased and installed in 2008 along with a basic Argos signal booster. The aerial input is directly into the booster then straight into the PVR. No other devices are connected.
Any suggestions as to what could be causing this would be appreciated! Surely it's not just the weather?! I have also replaced all coax cables with new leads and also replaced the booster.
