Please would some kind person give me a possible explanation as to why I cannnot receive anything from the mux on ch 60?
I get 100% from ch 58, and cannot see why just two channels higher there is not even a weak signal. Granted the aerial may not be wideband enough, yet when there were very low power stations on ch 63, just occasionally I could receive them. Nick, Hollesley.

With Sudbury finally transmitting on full power we read that with the introduction of 4G services by the moblie phone companies that Freeview may be disruppted for over two million viewers. If 4G goes ahead does anyone know if it will affetct Sudbury Freeview services? I read that some kind of filters will have to be connected to affected equipment to correct the problem. Sounds like more hassle.

Like Nick in Aldeburgh I also cannot get Channel 60 signal at all and this is in Clacton. All other channels stable and good quality.
Perhaps channel 60 is not, yet, transmitting at full intended power?

I am posting this at 1000 on July 11. I live at Alphamstone, about two miles west of the Sudbury transmitter. For the last three weeks or so I have noticed a major fluctuation in signal quality from the Sudbury transmitter. It is intermittent, mostly at this time in the morning about twice a week, dropping from 100% to 40% and back again. The signal strength does not change (80%). I have a very powerful aerial and am processing through a Humax PVR 9300 T. I did a retune about a week ago and all was fine.
This problem, which has only started recently, creates dropouts in picture/sound. I should point out that the weather is clear right now, just in case that is an issue.
Any help from this forum would be gratefully acknowledged.
Kind regards
Nick

Further to the above post, I see there is another Nick so I will change my posts to Nick A.
Just to say the time is now 1100 and the signal quality is back to a steady 100%. Any ideas ?

Nick A: The signal strength jumping up and down as you describe sounds like it could be signal overload, particularly bearing in mind your close proximity to the transmitter.

Hi Dave
Thanks for that. I looked at the website which addresses signal 'strength'. But my issue is with 'quality' not 'strength'.
The signal 'strength' stays consistently at 80%, even when the 'quality' fluctuates down to 20% .
So, I am still stymied. Thoughts ?
Regards
