VOS I thought you posted on another thread earlier with illustration that the HR20-100 really does not require a DECA filter, but was only needed because of the official DirecTV installers' "dumb idea" (your words at the time) hookup method for it?
DirecTV have changed [revised] their layout for the HR20-100.
I might even expect this to happen again as I'm not sure:
- why their first setup didn't work
- what makes their second setup work any different
- that there isn't another problem with "some" HR20-100s, where the issues that they're having is really related to the SAT signal coming in both SAT inputs and these are combining within the receiver to cause the problems they are having.
If this worked "as it should", then no filter should be needed if the splitter was between the SAT inputs and the DECA, since this mimics all other DECA installs for other receivers. DirecTV wasn't able to turn on the DC for SAT 1 on the HR20-100, when in SWiM mode, like they've been able to do with all the other receivers.
This means SAT #2, which they did get DC out, needs to be used to power the DECA.
Since SAT 1 & 2 combine internally to feed the two tuners, "there could be" a problem where both SAT inputs also combine, but this wouldn't be known/an issue until using #2 to power the DECA.
Not all -100s have had this problem and during the test group phase, we didn't even have filters for them.
Now they seem to be chasing a problem out of the field that some installers are resolving by swapping out the -100.
