Intermittent Reception Problem

[Shade]

Hi there :]

I have a Pace 1000 phase 1b with a funcard using RST HEX files, which used to work fine on all channels, in an ex-cw area.

I did change to a tit2 card, which worked fine until recently, but having problems reprogramming it (thats another issue)

Therefore i went back to square 1, reprogrammed my funcard, and put it in the stb. Most channel receptions are fine, however on some channels (notably 0/7 and the movie channels) theres a fair bit of jitter (sound and picture freezes every 10-15 secons for a second or so), as if the signal isn't coming through. However, on other channels (kerrang for example, which is a subscription channel) the reception is fine.

Ive tried reprogramming a spare funcard in case it was a dodgy card, but get the same intermittent reception results, so i guess the fault isnt at the card end.

I never had this problem 6 monts ago, so if anyone can shed any light on the matter, i would apprieciate it. If it is something to do with signal strength (big assumption considering it doesnt affect ALL the channels), is there any way i can boost it from the NTL coaxial port?

Thanks

Look at the signal to noise (SNR) value in the engineers menu - if it's below 30 then the signal strength could be the issue.

Otherwise these are typical symptoms of either (i) a tuner failure - you can swap the two tuners over (in fact you can leave the upstream one out altogether) which may cure the problem. or (ii) a capacitor failure on the mainboard (in which case happy hunting)

Then again the problem might right itself as the CC might be having trouble sending with those spacific channels to you because of works in your area, ask a neighbour if they are having trouble with thiers as well.
