In a first embodiment multiple power sources are selected and then combined. The system is implemented with a sampler of sufficient aperture bandwidth to capture the signal in question, operated at a clock frequency, dynamically chosen as a function of fLO and the desired fIF, to minimize in-band intermodulation products. When the sealing element is rotated by the drill string the ends of the sealing element abut the upper and lower support plate set respectively and seals against the pressure from the well and outside seawater pressure. Without a user scroll command, the electronic device automatically scrolls through the singular page such that each of the biblical verses is visible on the display while the corresponding audio signal is being communicated. The configurable parameters can be entered by a user using a graphical user interface. A second detector preferably detects an energy of an additional component of the input VUV beam.
