OK, thanks....just seemed strange that only that mux was affected

Hi Chris.se...thanks for your reply and apologies for the delay in response
I checked the email envelope and I get a fatal error message...I cannot paste it here for some reason

still having major problems with COM7 channels...the signal strength remains reasonable at around 70% but the quality is varying between 100 and 38% which is clearly the problem.....but what is the cause???.....ALL other muxes are received at 100% signal and 100% quality with no variance at all

Thanks Chris....yes, I did notice my duplicate post but that was because I again received the previously posted page of errors...I have tried 3 different browsers!!
There are no new 4G or mobile masts around - in fact there are no masts around for miles as we live in the middle of nowhere :) - IP23 8LP and served of course from Tacolneston -have tried Sudbury but Taccy was way better
Thanks for your tip about turning the gain down - I do have a 4 way distribution amp and am aware of problems caused by overloading etc...ALL the other muxes are absolutely fine, when I installed it many years ago I turned the gain down until the strength read 90% then tweaked it up gradually until it was just at 100....I have bypassed the amp completely and connected only the lounge TV which dropped the signal to around 80% on all the other muxes but COM7 dropped to the point where I couldnt receive any channels
I have a Televes DAT 75 aerial in bypass - i.e. without the PSU conected at all as it wasnt needed after full DTTV switchover (before full DTTV we could just about pick up channel 5 with it powered !

...I wonder if it's worth re-powering the MRD in the aerial and attenuating the signal before it goes into the 4 way distribution amp.....I believe the MRD is "supposed" to adjust to the required gain on various channels to boost where required and also prevent overload.....hmmm....might give it a go tomorrow

Thanks Chris...yes, I have a variable attenuator - a small silver metal box with in/out connectors and a knob....says 0-20dB...

...about to re-power the mrd I checked the signal and it has returned to 100% quality and 94% strength which is as it has always been......hmmmm....wonder if it will last???

Hi, is there a problem with the COM7 mux today?.... we are having very low signal strength and even lower signal quality on all the COM7 channels
IP23 8LP
