75
<WTRFALL>: Sets waterfall height (% of total panadapter height). A
higher percentage displays a taller waterfall, useful for seeing more
signal history. A lower number provides more spectrum height,
making real-time signals more visible.
<NB>: Turns panadapter noise blanker on/off and sets the blanking
threshold. Use the lowest effective setting. There's also an AUTO
setting. In this case, the panadapter noise blanker is turned on
whenever the associated receiver's noise blanker is turned on (see
[NB] switch).
<WTR CLRS>: Sets the waterfall color gamut. A higher number will use
brighter colors for a given amount of waterfall signal intensity.
<REF LVL>: Sets the panadapter's noise floor in dBm. If AUTO is
selected, the baseline will be placed at the average noise level. (You
can adjust how much baseline noise is displayed using MENU:AutoRef
Offset.)
<SCALE>: Sets the range in dB shown in the spectrum portion of the
panadapter.
<SPAN>: Sets the frequency range in kHz for the panadapter.
<CENTER>: Resets the center of the panadapter window to match the
VFO A frequency.
<AVERAGE>: Sets the amount of spectrum data averaging. A larger
number smooths out noise in the display; a smaller number makes the
display more responsive to changing signals.
<PEAK>: Adds a line to the spectrum display showing the highest
signal levels observed across the full frequency range.
