@freedishlover,I did try to change the skew of the LNB as advised by you.
I got the 10850 H 45000 TP which every one seems to be getting.
But signal deteriorated to almost 35% on both H and V TPs
Channels increased to 100 despite the signal fall but H channels were exact copies of V channels.
So reversed the skew back to it's original and moved it a bit more towards Telstar 18 position which improved the signal further so now I am getting around 70% signal on most channels of the V transponder.
Earlier I thought my receiver would catch both H and V transponders but did not know that just my moving the LNB skew channels would increase !
Thanks for the tip.
