The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.

David . HD needs a bit stronger signal than SD . So its possible that there is a small fault in your aerial/cable/connections . Not big enough problem to knock out SD but making the signal too weak for HD.

I can no longer pick up LBC or Classic FM since the recent retune of these channels. I have done the reset procedure of pulling the aerial out of the back of my NOWTV box & doing a rescan. Everytime I do this it shows 2 iterations of LBC & Classic fm but neither of them supply any audio.
I believe I am picking up reception from the Sudbury transmitter & I live in the CM8 1XE area.

Steve:

You should be getting very good reception from all muxes at Sudbury according to Coverage Checker - Detailed View

I'd try that Reset and Retune with the aerial unplugged again and perhaps at the end when it says no channels found, power it off, wait a minute, power on and check there are still no channels found, plug the aerial back in and do a new Tune for the channels.

Steve make sure you are using the right tuning mode . Some Freeview boxes have a complete retune mode and an 'add new channel mode '

It is a geat pity that Freesports is not available from Sudbury, as I am retired and live on a pension, so I cannot afford to pay to watch sport.

Rex Watson: Have you looked at getting Freesat? A one-off cost for the dish + box and installation (or reuse an existing dish & cabling if the property has previously had Sky at some point in the last 20 years).

Is it atmospherics causing out of area signals interfering with CH37 ArqB multiplex from Sudbury? The signal strength reported is low and has been for several days and quality can drop to 0% is currently 2% with FEC allowing the multiplex to be watchable but when it drops to 1% and below it errors out with loads of error blocks breaking up the video and audio. All other multiplexes are behaving normally in high 90's to 100% quality.
Using a wideband log-periodic outdoors aerial and 8 way distribution amp with 10dB gain per output and 4G filtered and low loss double screened co-axial cable.

I know nothing about the technicalities of aerials etc but what I do know is that for the past 10 days, living in Ipswich with a very basic aerial set up towards Sudbury, I haven't been able to get any of the ITV channels until mid to late evening. Normally there are very rarely any problems getting the "main" channels, and as many of the Freeview ones worth giving house room.
