As I recall, my DSR922 is rated at 450 ma for the LNB(s) supply. Is
that for both (Ku and C) or is only one LNB lit up at a time? The new
PLL LNB I ordered is rated at around 300 ma, which doesn't leave much
for the Ku one if they are both on at the same time. I suspect that
they switch as needed, but would like some clarification on this if
anyone knows. Thanks.

FWIW, it appears that the chip that supplies the power for the LNB
gets turned off when that chip (band) is not selected. Guessing then,
that there are separate chips for C and Ku. Any way, both are working
fine with the new LNB.
