Well, the Dish Plus L.O.description I gave was a side issue which perhaps I really didn't need to go into in any depth. Just suffice it to say briefly AIUI, on the Dish 500+ and 1000+ LNBF each Dish Pro (DP) or Dish Pro Plus (DPP) LNBF actually uses two L.O.s due to the frequency stacking. 10.75 and 13.850 GHz to convert the 11.7-12.2 GHz FSS band and 11.25 along with 14.350 GHz to convert the 12.2-12.7 GHz BSS band. But none of this is relevant to the issue. Again I agree, the RDBS band will need its own L.O. for reception The present 18.050 GHz one used for the Ka bands is useless for it.
