Hi, I have just done an install with slimline dish, swm 3 lnb, 8 port and PI21. This is connected to an H20. I have aligned the dish with a digisat 3 meter and an ASL with the PI. I get levels of about 84 on the 101. When I then connect the set top box and start up I get 0 values on all 101 transponders. Any thoughts?
