Saw a diagram of SWM8, .......

That is correct.

yes the swm tech doesn't need bbcs

Thanks for the replies, too bad I don't have the knowledge of how this stuff works.

Feel free to ask as many questions you have and you will learn a lot along the way from all the great members here.

Just out of curiosity, what happens if you leave a BBC inline with the SWM feed? I assume that a receiver operating in SWM mode would never signal the BBC to do any broadband converting, so they would just stay in passthrough mode and everything would still work.

Nothing comes on, i hooked mine up and was going nuts until someone on here posted, it'll just say searching for sat. signal until u remove the bbc

i hated bbc's to begin with, buying the SWM and installing it were the best things i've done with D*, changed my whole set up in my house

That's odd (and poor design). As long as the BBCs are left in passthrough mode they shouldn't alter or block the SWM output frequencies. Those are the same frequencies used to transmit other transponder outputs when operating in non-SWM mode and those signals pass through the BBCs unaltered just fine, so why would the BBCs block or alter the SWM output signals?

What about an open line using the SWM8, with no receiver/tv on it. That is, an RG6 line that is ran to another location such as a bedroom, deck, etc. where there is no permanent receiver/tv at that location. Can it be left open, or does it need some sort of termination.

Seems like it sees the BBC and thinks it's on the old style dish.. so it never switches to swm mode..

So they must be doing their auto-detection wrong. If you detect a BBC, that doesn't mean that a SWM isn't there. Presence of a SWM should should take precedence and cause the receiver to operate in SWM mode even if there is a BBC in the line. That's evidently what the H23s (with built in BBCs) do. Maybe with the latest software releases, the other HR2xs with external BBCs now work like the H23s do.

Or you can follow the directions :grin:

But since we know that variations from the given directions happen all the time, it would be wise to do the auto-detection correctly and automatically handle the case where an unneeded BBC was in the line. They had to do the SWM/BBC detection correctly for the H23s since you can't remove the BBCs from them, so they may as well do the same for the rest of the HR2x line.... maybe they already have now that they were forced to do it right on the H23s.
