Hi guys been havin trouble with my box for a few week now,ever since virmin changed the net Id in my area, I live in the Wigan area and I am scanning my box on the net id off my v/m box but still getting the same result.lost channels and the channels I do get are all crackling and merged together any help please

[ando23]

I don't know but try scanning an area close to u am in Knowsley but I scanned Preston an all works fine for me

[cavanagh]

Tried all net id's near me still same result doin my nut in , ne other ideas please

[ASEK]

what date is s/w on it?

[cavanagh]

11/11/12 my signal is only at 75 when scanning but has always been at that level and worked fine till they swapped the net id

[cactikid]

did you factory reset first then power off at back,remove lan and scan from direct feed,then choose your net id from the list.insert lan and reboot network if needed.

VM are slowly moving most transducers from QAM64 modulation to QAM256. Unfortunately this scheme requires signal levels to be in a much narrower acceptance range which seems to be causing problems for those that already have marginal signal levels. Even VM's own boxes are affected by this problem.

If this is the problem then the only things to try are either signal attenuation (if its too high) or signal amplification (if its too low). The downside of this is that it tends to introduce noise which can lead to a lower quality signal thus causing more problems of the same type.

Got vm comin out monday see iv they can up my signal,thats my last option iv that dont work im out of ideas cause i have tried everything you guys have suggested

[cactikid]

what are the numbers on your vm box as i will check an old post for info.

You have to be careful using numbers generated from most boxes. At best they are extremely unreliable. One box can say one thing whilst another seemingly identical box can say something entirely different. There's absolulutely no attempt at calibration on these 'informational' displays.

Bit error rate (BER) display can give more trend information than pure (mostly arbitary) signal power levels but even these can vary significantly due to tuner tolerance spreads during manufacture. The plain fact of the matter is that one box may not function on a particular marginal signal whilst the very next one off the production line may work perfectly well.

40967 which is comin up as preston on my kv box

[cactikid]

looking at an old post. NetId - 40967 (a007) - Preston 1-ex tw

Its still the same -

NetId - 40967 (a007) - Network Name - Preston 1

The default frequency may of changed from the old days though. Its now on 411Mhz, 64QAM, symbol rate=6952000. The area has had the QAM256 upgrade so most other transducers have already switched to QAM256.

[cavanagh]

So can i change the frequency and symbol rate? Dont mean to sound stupid, really appreciate all ur help

[cactikid]

there should be a changeable qam setting from 64 to 256,wont do any harm to give it a try.
