some of the old receivers like the extremeview magnum will show a signal strength and quality but no lock when aimed at dcII signals.You have to enter the tp info manually; freq and sr.
I think the old coolsats did also.
An interesting video...thanks for the link...
At one hour long it is a little more time than most would put in. Be better as a FAQ or PDF file. No real secrets, but does offer a little more info that we had had on DCII.
