Had a Dishnet tech guy do the hookup originally to 2 SW21 switches with success altho due to elevation here am only able to pick up the 91 sat.
I'm confused - if you've never been able to pick up the 82 Sat, you've never had HD, since (as QCK says), all HD content is on 82.
If you once had signal from 82 and have now lost it, it is probably because you are now out of Nimiq 4's footprint, as per QCK's other post. There have been a few posts from snowbirds over the last few months indicating that with VERY accurate pointing, it is still possible to get some signal off of Nimiq 4, but you're chances drop with each mile south. Getting a larger dish might help.
