Does anyone know what the technicall differences are between the two Zinwell 6x8 switches? The 6802 and the WB68? I was under the impression that the WB68 was the only one that can work with the A9 dish.... well... just had my install yesterday and the 6802 was installed, and it is working perfectly... So any ideas? As in, when we see something on Sat #5 will I start to have a problem?
