First of all what kind of dish and LNB did you get? For UNIVERSAL LNBs the L.O. frequency is 10,600 MHz and for STANDARD LNBs it is 10,750 MHz. You must set up your receiver accordingly. Do some reading in the
VTV4 forum and get some ideas. Also check out
www.lyngsat.com for information on T5 (now called
IA5).
