well dear this thread will not help anyone as different models of stb ill give different readings, infact old and new model of lnb will also give different readings. if u have new model lnb and normal stb, to check reading for each transponder, u will have to first choose one channel from each tp, change to that channel, go to signal meter and then take out lnb wire from back of stb and then recvonnect to give right reading as if u directly chek signal reading, it will give wrong reading like in 11010 h channels like channel 100, it will give 255 reading which in reality is 218-222.
similarly in new multi lnb and there is earthing in ur house, if u switch light on or off, the signal in other connection bcomes blank for 2 seconds. i too got installed old model lnb as it gives better quality picture and has no such issues. new lnb's r of low quality. tata sky tried best to serve premium products till late 2009 but people started bashing thema nd ultimately now to bcome little cheap,tata sky too gives lnb abd stb of not that great quality as it used to b but still service of tata sky is top notch. hopefully people will stop crying for cheap rates as its eating quality. earlier tata sky stb ,,tata sky plus stb were little costly but quality was super, this is the reason why u see that tata sky plus hd is of much cheaper cost despite having many features than old tata sky plus which had limited space but was of good quality. all these players like videocon, airtel, big tv, dish tv started this low quality equipment trend . fortunately atat sky stb and software is still the best and does not have bugs like dish tv, reliance stb which have so many issues
