NOTE. The Viterbi Rate Auto option will not work correctly if the
Viterbi rate is 5/6. If this rate (5/6) is known, or suspected, then
the Auto option should not be used.

tone.
Invert Spectrum
The sense of modulation may be inverted due to the number of
mixing stages in the installation. Enabling the Invert Spectrum
checkbox will invert the L-Band output.

the channel and is receiving the signal correctly, the Front End
Lock (FEL) indicator will light up green. When a signal is
present but no lock is achieved the indicator is red. When no
signal is found, the indicator is gray.
