the LNB connector you are referring to. Plus, I don't have right now any
voltimeter, but if needed I'll grab one from work tomorrow.
So, as I started playing with my A700 card, I discovered that the
input-connector on the card, where one attaches the coax-cable to the
lnb/dish, sent out wrong voltage.
13V / 18V was swapped. So I patched mt312 driver and added the setting
voltage_inverted to reverse it.
Instead of just guessing what happens it is interesting to just call the
dvb-apps example app set_voltage and measure what voltage the hw outputs.
