    Abstract: Broadcast data receiver apparatus is provided. The apparatus includes a broadcast data receiver (BDR) connected to at least one LNB. The BDR provides a power supply to allow operation of the LNB. At least two analogue to digital converter sampling points are provided to allow the input and output voltages to be measured at the LNB, thereby allowing the voltage drop across a linear regulator (8) of the LNB to be assessed. Control means are provided to control the power supply from the BDR to the LNB in response to the voltage measurements obtained.
