Below are all of Richard Hawkins's postings, with the most recent are at the bottom of the page.jb38. Humax HDR Fox T2/1TB. I have tried the HD mux with the Humax fed directly from the aerial and have done the same with he TV.Both show the same intermittent breakups on the HD mux.I have on order a group B passive bandpass filter. This may have no effect on the current problem but will hopefully future proof my set up from any out of band interference.
How can i find out exactly what engineering is being done at the TW transmitter and when it is due to finish? I have an automated reply from BBC Recption which states that intermmittent interference problems will be followed up :) !

Following my posts on the 16 and 17th regarding intermittent breakups on the HD mux channel 47. I am Not alone! A friend who lives about 1/2 a mile north of me with the same post code has the same problem, It is just worse than mine!
I do not understand the above post.AFAIK all analogue TV transmissions ceased from the TW transmitter on the 13th june. I find it hard to believe that the HD Mux is working normally as two of us have the same breakups spoiling HD reception.
I have tried reducing the aerial signal by putting two splitters in series in the aerial lead. This has not solved the problem and all the other Muxes are perfect as before.

I have an external roof aerial and I have excellent reception of all muxes apart from intermittent breakup of pictures and sound on channel47 being the HD mux.
Signal strength on my Humax box is a steady 75% on all muxes. My panasonic IDTV shows 100%. However the quality indicator drops down from 100% and the BER, which is normally zero jumps to a high value as the picture and sound breaks up.
I have installed a mains power condtioner and switched off all other electrical equipment in the house. It would appear that there is external intermittent interference causing the problem.
Could the transmitter be the source of the sporadic breakups?
