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.
Are there any planned engineering works or unexpected transmitter faults on the Sudbury (Suffolk, England) mast?

Clacton-on-sea
I live in Thorpe-le-Soken, which is shown as a fringe area for Sudbury digital transmissions. However, with a high gain antenna and masthead amp it is OK.
I have a problem with routing Sky to other TV's in the house using RF2 output. I get vertical striations on the picture due, I believe, to adjacent channel interference. RF2 is tuned to channel 68 currently. Any suggestions for a better channel to minimise the problem. A final point. The striations vary in intensity and seem to be worse in the evening.
Any help appreciated.

Keith Banks: It may be 4G services operating in the 800MHz band (C61 to C69). The coverage checkers of 3, O2 and Vodafone indicate that their 4G networks don't serve your area yet, which isn't surprising due to its relatively sparse population.
The only thing I can think is that EE is operating 4G using it 800MHz allocation. Prior to the auction EE was allowed to use some of its 1,800MHz allocation for 4G services. 1,800MHz is what its GSM (2G) uses.
The lower part of C67 is given to EE for "uplink" - that is for handsets to communicate with base stations - which might explain why the interference varies, i.e. because the transmitters (handsets) are moving and aren't always broadcasting.
Beside your posting click the link to "K's Freeview list". It's really a try it and see. C36 is clear for all so might be best to try first.
