Sudbury (Suffolk, England) Full Freeview transmitter

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 ?

Hi David

Did you have any issues between 0900 and 1100 this morning ?

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

Thank you all.

Questions:

1. the site Dave sent me to says that any signal above 75% is too high. Yet, that is what it has been registering since the day I installed it a year ago and without any problems. The problem has arisen and been intermittent since the signal boost at Sudbury in June. If I install an attenuator will it fix the problem ?

2. it does seem odd that I am the only person having this problem (or at least reporting it on this website). this leads me to believe it could be a localised issue. Yet, I have done the usual debugging (including the tip from KMJ, thank you). No difference.

And thank you to Les. I did toy with a Freesat, but am now fully invested in Freeview. So for the time being, and provided I can fix this, I will keep the status quo.

Sign me Nick A, frustrated but still working it !

Me again. Every channel is now completely stable. No reboot since this morning and signal strength at a steady 80%, signal quality at 100%. Hmmmmmmm.....

and now it is back to the intermittent quality issue.......

i am assuming that if the signal 'overstrength' was an issue then the 'quality' would be consistently poor. it is not. it fluctuates from 100% down to 40% and back, and then is perfectly fine at 100% for half an hour or more.

Hi Dave

Sorry, our posts went up at the same time. Thanks for your further notes. I will try a few things.

The aerial is in another location. I tried moving it off about 15 degrees and have reduced the signal strength down to 70%, but the quality problem is still there. So i will totter out and get an attenuator tomorrow.

But logic says to me, if i can reduce the signal to within tolerance and the problem remains, then the strength issue may not be the problem.

Yours ever hopeful,

Nick A
