FYI... thanks to Chuck and WB this link is up and working. WB sent us a new dish, overnight, at no charge to see if that fixed this link. The new dish DID get the link up. From -85 to -59 now.
It was either a bad dish, or mis-aligned. Seems we were aligning with the red marker on the dish (i.e. same as a DISH Network dish), and the WB sticker on the dish is for the BOLT (not the red marker). I thought we checked that, but maybe not. It's been a while now. Either way, thanks very much to Beehive for working with us on this. We'll be buying these dishes going forward for all our links! And thanks to everyone else to had input. Jayson On Tue, Oct 20, 2009 at 7:18 AM, Jayson Baker <[email protected]>wrote: > Spent another couple minutes on this link today.
