PANADAPTER
The K4 supports independent panadapter displays on the LCD and on
the external monitor. Both spectrum and waterfall can be customized
to the user's requirements. You can select single panadapter mode
(VFO A or B) or dual panadapter mode (VFO A and B).
Panadapter Window
Frequency markers are displayed along the top edge of the
panadapter window, and signal strength in dBm along the left edge.
Other icons will appear in this area when applicable, such as "NB"
when panadapter noise blanking is enabled. A letter (A or B) in the
lower-right corner of the panadapter window shows whether it is
associated with the VFO A or VFO B frequency.
If the VFO A cursor is off-screen, a blue triangle icon will appear at the
top edge of the panadapter to show whether it is off-screen to the left
or right. A similar green icon is provided for VFO B cursor off-screen
indication.
Customizing Panadapter Appearance: Using the menu, you can
change the signal strength scale from dBm to S-units (Spectrum
Amplitude Units), turn frequency graticules on/off (Spectrum Freq.
Marks), and select different types of spectrum trace fill (Spectrum
Trace Fill).
Mini-Pan Window
The mini-pan is a secondary panadapter provided for each receiver. It
shows a narrow range of spectrum for fine-tuning of signals. (The data
points are not simply magnified; they are resampled to ensure high
resolution.) To display the mini-pan, tap the S-meter for either
receiver. In CW and PSK modes, AUTO-spot centers this signal by
