Chris.SE:

I hope I'm not speaking out of turn or breaking some site etiquette as I've never posted here before, go easy on me :-)

I have lost some channels after the Wed 4th Sept. re-tune. It appears I have lost all the channels on Multiplex com 7 and multiplex com 8. These were previously fine before the re-tune.

I live in Bangor NI, and I'm using a BT YouView+ box, model:DTR-T2110

Can someone explain to me why this has happened and what I can do about it?

Are com7 and com8 still being broadcast? I read on ukfree.tv that these are due to expire on 21st June 2020. Has this been brought forward?

Have their transmission frequencies and/or power output been changed? would an aerial upgrade solve this?

Thanks CARL READE and Chris.SE for your replies.


A quick re-cap for the benefit of anyone else with the same problem:

I'm in Bangor, and receive Freeview via a BT YouView+ Box model: DTR-T2110

Prior to the re-tune on the 4th Sept. I was receiving all available channels via a standard looking, approx. 35 year old, chimney mounted aerial.

After the 4th Sept. re-tune I found I was missing all the channels on four multiplexes:

Com 7
Com 8
LBT
Local

After reading comments here about lower broadcast power on com7,com8 and a need for a wideband aerial, I purchased a new wideband, hi-gain aerial at the weekend (Tristar 278844tr). I mounted the aerial in the loft as I didn't have easy access to the chimney.

After a re-tune of the YouView box, all channels have now been restored.

The signal strength and signal quality of each multiplex, as measured by the YouView box is:

Com 7 Sig.Strengh. 90% Sig.Qual. 100%
Com 8 Sig.Strengh. 80% Sig.Qual. 95%
LBT Sig.Strengh. 88%. Sig.Qual. 20%
Local Sig.Strengh. 88% Sig.Qual. 20%

All other multiplexes are Sig.Strengh. 100% Sig.Qual. 100%

Please note, that even though the signal quality of LBT and Local is only 20%, the picture quality is perfect.

CP - My first port of call when my 4th Sept. re-tune had gone awry was the official Freeview website:

https://www.freeview.co.uk/tvchanges

There is a freephone number 0808 100 0288 to deal with re-tune issues.

To my surprise, after explaining my problem re. loss of specific multiplexes, they arranged for an engineer to come out, free of charge.

When I sorted out the problem for myself, I called back to cancel the engineer visit.
