Having an intermittent problem with signal quality on a Digivox-T. Normally the signal quality is over 80% with signal level of 84% approx. Then sometimes I get pixelation problems, which sometimes is followed by picture loss and message "Bad or scrambled channel". The Digivox-T doesn't seem to like loss in signal quality and sometimes reboots when this happens. What I have noticed is that when this intermittent problem occurs the signal quality starts flucuating greatly, varying anywhere between 40 and 70% Now sometimes this problem corrects itself and everything is cool, other times it persists for quite a while. anyone experienced a similar problem ? Is it likely to be problem with Digivox or is the aerial slightly off? It wasn't particularly windy when problem occurs but I guess there's also potential for a little movement. It could go an hour or two without this problem occuring, have checked all cables. Bit awkward for me to adjust aerial so trying to get idea of what is the likely cause before I try that,. Any known issues with tuner in Digivox? Also, as a matter of interest what fixes are in v3300 of firmware? I'm running v3200.
if the signal is too strong would this cause the signal quality to fluctuate so widely? I was monitoring it last night when everything was stable and some frequencies were showing quality of up to 89-90%, others were 80+ Signal level was 84-86% if you think and attenuator would help then how much do you suggest to attenuate the signal? down to 70-75% ? Might take me a while to get my hands on an attenuator, any workarounds?
scandalou, have been thinking about this again. are you sure about the attenuation approach? the signal level is about 84-86%, I've read that this is optimum level. Instead, it is the signal quality levels that intermittently go up and down causing the pixelation and "bad or scrambled channel" message. do you think this could instead be caused by poorly aligned aerial? If the aerial is aligned correctly should there be a uniform signal quality across all frequencies/channels?
Hiya , it would appear to me that your problem is caused by loss of signal this can happen due to bad weather such as heavy rain.It could be all to do with alignment and line of sight and depends on your setup and if its within the threshold to cope with the climatic variations. So it really down to you trying a few things and being methodical . When it goes bad again check the weather and make slight adjustments to your aerial to see it fixes it , also try a variable signal booster and then last resort a different aerial that can compensate with the signal loss by increasing the captured available signal
Hi razor99, Had the problem few times with eurovox, the supplier is upgrading the network to transfer to digital required by law. This may last a few weeks from 7.00am -11pm 7 days, some boxes are sensitive to it others are not the way round this is to buy a varible attenuator from B&Q £8.00 and adjust the power until it corrects. The supplier has updated the original boxes to cope with this fluctuation in power so it won't show on the supplier boxes. Signal strenth can drop to 75% with a perfect picture until the turn the power up again.
suse103, problem was the god damn power supply. had read before about this issue but it didn't twig with me over the past few days as the reason for this problem. my psu was only 12V (although I thought I read it could deliver more), swapped it out with an 18V and everything is perfect now. interesting though that the 12V was at times adequate to drive the downconverter.. obviously needs a little more ooomph thanks for your help.
