- Of particular interest to many users will be the CPU load (excessive CPU load may cause sluggish behaviour or freezing of the computer), and Audio latency. Apart from DDC bandwidth, CPU load may be minimized by reducing the Demodulator filter length (...
- Note: When measuring sensitivity using SINAD, it is very important that the Audio Filter is enabled and the cut-off frequencies (and for FM measurements, also the de-emphasis) are set according to the specified test conditions. Proper audio filtering ...

Release the Shift key to exit this mode.
Under the main frequency display there is a Band description window:
This window shows the band allocation of the currently tuned frequency. While
the displayed band descriptions are specific to the North American standard
band allocation, they are based on international treaties and therefore are
generally applicable worldwide with minor differences, and can be easily
edited by the user.
The displayed band descriptions can be overridden with a call sign or a user-
defined description of a particular frequency stored in memory. This overrides
the band description for that particular tuned frequency only.
It is also possible to change the naming and frequency allocations for entire
frequency bands.
This can be done by editing the file called bands.csv in the program
installation folder (usually C:/Program Files/WiNRADiO/G39DDC/Defs).
This is a standard comma-separated-value format file which can be edited
using a spreadsheet application, such as Microsoft Excel. Please note that
with newer Windows versions, you will need administrator privileges to be
able to edit this file.
