However, when you do this you are seeing the 8 MHz *IF* signal.  You
are not seeing the effect of the final mixer, low power amplifier or
100W amplifier if installed.  This "kludge" shows only the effect of
the DSP modulation process - compression and EQ - and does not always
represent the "goodness" of the final transmitted signal.
