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.

John: Its an eight year old PVR - could be that the software just doesn't allow it. My old Sony PVR's EPG has stopped working, and I suspect its a software problem that cannot be resolved. Might be time to just upgrade.

But they have all been working with COM7/8 this has only just started to affect our PVR's all over the country and I believe Panasonic were affected as well so I am told. From my point of view because I do not use COM7/8 I am happy to just carry on because it has been a very good PVR. Something strange has happened and it is a shame that so many users have been affected.

Has anyone tested are you able to get good or even decent signal with good indoor antenna in Cambridge?
I live in rental apartment close to Cambridge city central and we don't have outdoor aerial antenna at all and landlord doesn't allow to install one.

It is highly unlikely that you will get any reliable reception in Cambridge using an indoor aerial (in the same room as the TV). You are simply too far away from the Sandy Heath transmitter. An external aerial mounted on the roof or chimney stack is needed.

Dear sir, I am the area manager of some residential sites in buckden and some of the residents are having issues with their signal on HD channels and on some non HD channels the local transmitter is sandy heath which has shown no issues on their website.
Please can you advise as we have a new satellite dish and transmitter both working fine?
Please can you email me or call me on 07889230897

This website has no staff to do as you request. We contributors are purely voluntary wishing to assist people having reception difficulties.
Sandy Heath has no reported engineering work at present. So your residents need to contact an aerial contractor to check their systems - or you could do it for them as you are the area manager and have a responsibility to assist them.
You don't saywhether they all use a communal system. If they do then it is the management that is responsible for correcting any faults.
