How come there is such a high current drain to drive the switch plus the LNBs? From what I understand, the switch should only power one LNB at a time. Usually the switch plus the LNB should not drain more than 300-400mA, or am I wrong here? > Is there another way to solve this ? > Maybe add a module parameter for people who want to override the > default ? I think this could be done. Nevertheless, the card would still operate outside its specification. Regards André
