It seems that my Spiderbox 9900HD 's tuner is on the blink.
I am not getting any signal on most H frequencies but all OK on Vertical.
I do have a SB 6000 HD connected to same dish and dual LNB which show no problem at all with these H freuences.
Any suggestions how I can check this completely?
I still have to change receivers to the SB 9900 connection to find out if it is an LNB problem (just been told to do this by a friend)
