Its not just daylight hours over here. Nothing at all day or night. I've tried different boxes, tv's and pc tuner. If there is interference then its pretty specific to c31.. Do any other transmiters use c31 anywhere for digital, or did they, did they have similar issues at some point. My only thought now is that perhaps all our receivers have some common problem, electrical noise generated from cooling fans or earth leakage - just grasping at straws really.

I've been googling 554Mhz and c31, there are some comments on different forums about similar issues in other parts of the country. A few people have come to the conclusion that there is indeed something about that particular band which may suffer from interference generated internaly within the componants of reception equipment or tv's (i'm not refering to a modulated rf output). Some people have rectfied it by buying new equipment (yeah right... My equipments new and I cant fork out for newer stuff - again!) others by doing weird and wonderful things with tin foil around the back of the tv which is not recommended..

Regards the c31 issue, I've been running further tests on the signal I'm getting and can say it isnt anything to do with local interference or the equipment I'm using.
I've been using a diagnostic program on my PC called ScanChannelsBDA_UK which allows me to examine the frequencies being recieved, it also provides me with the 'network information' (Lists the region, multiplex information, parent transmitter as well as relay transmitter frequencies. This then generates a table with the Channel, LCN, SID, Vid, Aud, PMT for each one.
Every frequency lists on there properly apart from.... C31; which gives signal strength and quality information (in line with the others) but insists that "no network information" is being broadcast. So on C31 the channel list, Vid and Aud program id (PIDs) are all missing. So, it appears there is a broadcast issue.
Also, the program discovered a weak digital signal on frequency 546Mhz (-166Khz) which would be Channel 30, perhaps the closeness of this is causing issues? I can only think that would be either Belmont or Fenton but they are a distance away..

Hello John. Something weird and wonderful has happened. I tested the signal again and all the PID information for C31 is there, I have now managed to retune all my equipment including the pc tuner. Nothing has changed in the setup from earlier, the signal levels and quality remain as they were but the 'network information' is now completed - how odd.
Is it really sad to be overjoyed at getting mux 2?

Whilst its nice to be enjoying mux 2 again I dont know what happened or why, or even why others still have difficulty when my problems seems to have cleared up. The signal does appear weaker than the other mux's though, only about 50% strength, the signal on c30 comes in as yorkshire so I assume its belmont and that is 52% strength now! Perhaps there is an invertion affect as I cant understand why that would be stronger than waltham.

Still nothing this morning either for me on c31.
