Fix C/Ku Label and Change switch frequency

* The C/Ku label was 5150/11700, in spite of the fact that the local
  oscillator frequencies were 5150/10750. This label is now changed to
  reflect the correct frequencies. Just to be clear: the frequencies
  themselves are unchanged, still at 5150/10750. Only the description
  changed.
