PE16 6BT Aerial on top of a two story house, very good reception for 14 years.
My problem is C52 COM5 all other COMs have really good signal so why is this particular multiplex showing such bad reception or no signal at all.
Aerial points on the ground floor and top floor are excellent. But middle floor bedroom is the one causing the problem if I want to watch COM5 multiplex. Any advice would be appreciated.

John: Do you have an amplifier or powered splitter to distribute the aerial feed to the various sockets around your house? What signal strength and quality readings do you get on the other multiplexes on the middle floor bedroom TV? What signal strength and quality do you get for COM5 on the other TVs where COM5 is working?

I have an amplifier to distribute the aerial feed around the house. On COM5 where it is working fine on other parts of the house Signal is 97% and Quality 100%.
In the bedroom it is Signal 16% and Quality 25%.
The funny thing is it has just come on when I went to check to get the signal check but often or not it would be pixelating or no signal.

John: Try taking the bedroom TV to one of the other working sockets if practical and check the signal strength/quality for COM5. If that results in a similar signal strength and quality to the TV normally connected at the socket you're using to test, that would indicate that there is a fault somewhere between the bedroom and the amplifier. It would be worth making some simple checks such as replacing the cable between the TV and aerial socket with a known good one and unscrewing the socket to check the connections on the back, also check the cable and connection at the amplifier for any signs of damage.

I have now ordered a better quality cable arriving Wednesday also the bedroom socket is a good quality one but I will check for bad connection. By the way it's a good quality PVR and I have tested on other sockets and it is fine.
I will also check the amplifier which is in the loft to make sure all is well. Thanks for your help.

I checked the aerial socket and rewired, then I got the better quality aerial lead so the good news is Sky news and Multiplex C52 are going great. Thanks for your advice.

IP270EE - has there been some sort of change recently, I used to get the HD channels (Via C21) with a rock solid signal, but over the last 2 weeks, there has been disturbance - or no signal or quality at all. I am wondering if it is co-channel interference from the recent changes? Or has the MUX at Sandy heath, had an unreported fault? All other Sandy Signals are OK & I even receive the weak Local Cambridge TV from Maddingly. So I doubt it is an aerial fault.

Hi,
I wonder if you have an answer to this problem. The Digital Stream PVR which was first launched in 2010 and is used by many users all over the country and is an excellent machine. Up until recently we have been affected by COM7 and COM8, let me explain. If we do not scan in these two Multiplexes our PVR's work perfectly. But any attempt to scan them in or use any of the channels within those Multiplexes then this is what happens. The PVR's get stuck on "LOADING' or stuck on "BYE' and will not shut down. On our thread on AVForums the advice given for the time being is for all users to try resets etc but not to use any channels in COM7/8. All other Multiplexes are fine. In my case and like many others the Digital Stream is doing what it is supposed to do without scanning in COM7/8. Any advice would be appreciated.
