I installed a sg2100 motor to drive a 36 ins dish . all the setting was done correctly from the manual instruction .I am using a invacon lnb with two Linear and two circular connections. the connection to the motor ran via a diseqc from the lnb which is used to connect one linear and one circular port of the lnb. I used USUAL on my Viewsat Ultra for the motor setting. I was able to drive the motor to to locate these sat. 110,119,91,82, and 61.5 , I am getting an average Signal of 67% and quality 87%. I am able to scan these sat watch these channels without any problem. Now the mystery is I am unable to get any quality from any of the FTA birds for 97 i am getting good signal strength 70 % but 0 quality. i tried other FTA birds with the same results. Could it be the Diseqc that is preventing me from communicating directly with the fta SAT..I assume all is well with the the installation if I am able to to communicate with % bird easily .
