I'm having a strange issue that seems to only affect the LPB mux on 87 west. I'm using a Manhattan DJ-1997, 90cm dish, and a geosatPRO PLL LNB.
If I watch any of the channels on the LPB mux (11807 H 11149), they are fine for a few minutes and they slowly get choppy. A blindscan finds this at 11811, if I edit the TP manually to 11807, it gets a *little* better but not much. If I change to any other TP and then back to this mux, it's fine again for several minutes.
I don't seem to experience this on any other transponder on this or other satellites. Quality remains a consistent 60%. It does not seem to be due to DVB-S2, as the PBS feeds on 121W are fine with similar signal quality. Is there something else about this TP (FEC perhaps?) that makes it trickier to keep locked?
