Ok - I may give it shot. I guess even if I have to channel up/down it isn't too big of a deal.
Until I can talk myself into some spendy LNBs for the mesh I think I'll use it for C-band sats and keep the SG-2100 around with a QPF-031 on the P*. No matter how I hook it all up I'm going to need to involve a 22k switch or two in there some place. This will be especially true when I fire up the C/Ku feedhorn on the mesh.
I guess I'm looking at either a DiSEqC or a 22k out at each dish to switch LNBs.
Maybe this is why Invacom made ther QPH / QPF a standard LNB...
