Hi. I am using 3 lnb 108, 95 and paksat through 8 port diseq. I have single solution lnb for paksat. My problem is that when i switch channel from paksat to 108 or nss 95. It often does not catch signal of vertical polarity channel but it catch horizantal polarity instantly. And when i switch from horizantal polarity of nss or airtel to vertical. It then catch signal instantly. And it happens on 13v/18v lnb power. When i do 14v/19v power through receiver option... All works fine.. kindly tell me what is the issue ?
