Under these buttons 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, they
are based on international treaties and therefore are generally applicable
worldwide with minor differences, which can be easily edited by the user.

The 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 a particular frequency only.

description for a particular 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
WiNRADiO installation folder. (This is a standard “comma-separated-value”
format file which can be edited using a spreadsheet application, such as
Microsoft Excel.)
Did you know?
VFO stands for Variable Frequency Oscillator. This is a historical term dating
back to the era of analog tuned radios. Before digitally tuned receivers were
invented, there was no easy way to store and recall frequencies. Professional
receivers had switchable oscillators where the oscillators (and their variable
capacitors) themselves served as analog frequency memories. The name and
the net effect remain, but the principle has changed: There is no need for
multiple oscillators in modern receivers to implement this function. The
frequency is simply stored in a digital memory.
