Tapping the Panadapter reveals plus and minus magnifying glass buttons located in the upper left
corner of the Panadapter. Tap these buttons to zoom the Panadapter in or out. Zooming out (-) will
double the bandwidth presented in the Panadapter while zooming in (+) will halve the bandwidth.
The frequency at the center of the Panadapter will remain the same after each change in bandwidth,
except in the case where the Active Slice Receiver is not in the center of the panadapter. In this case,
the panadapter will be re-centered on the slice before the zoom operation.
For more precise control of the zoom, touch and drag anywhere on the frequency labels located at
the bottom of the Panadapter.
Dragging the frequency labels to the right zooms in, dragging to the left zooms out. With this method,
the frequency at the point where your finger was located will remain stationary in the Panadapter.
Next to the plus and minus buttons located in the upper right corner of the Panadapter display, you
will see the B control. Tapping this control changes the zoom level so that the entire band that
contains the Active Slice Receiver is displayed on the Panadapter. Tapping the control again returns
the Panadapter zoom to its previous level.
Next to the B control, the S control performs a “zoom to segment”. When activated, the Panadapter
zoom is adjusted so that the segment (CW/Phone) of the band that contains the Active Slice Receiver
is displayed on the Panadapter. This control is available as part of the set of controls that can be
mapped to function buttons. See section 30.4, Function F1-F6 Tab for more details.
When zooming out of a Panadapter there are certain points where the amount of data needed to
create the display must be doubled. As this occurs more noise will be included in the FFT bins
comprising the display which will cause a noticeable increase in the noise floor. The reverse occurs
when zooming in on a Panadapter. Each time one of these thresholds is crossed, either zooming in
or out, the noise floor will increase or decrease by about 3 dB. If the displayed spectrum after the
zoom operation exceeds the width of band pre-selectors in the FLEX-6500 or FLEX-6700 the radio will
switch to wideband mode, which causes the radio to open the Bandpass Filters to their maximum
bandwidth. When this occurs, any Panadapters using that antenna will display in the top
right corner to indicate that they are in wideband mode.
Note: The FLEX-6300 is always in WIDE mode and will not show this indicator.
Just to the left of the WIDE indicator is an indicator that shows if the preamplifier is active and if so,
at what level. A complete description of the preamplifier control can be found starting in section
22.9, Using the Receiver RF Gain/Preamplifiers.
If the Panadapter is on a Transverter (XVTR) band, an indicator appears to the left of the preamplifier
indicator. A complete description of how to setup for transverter operation can be found in section
24, How to Configure Transverters.
