- 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 ...

Power Switch
The Power switch, located at the bottom-right corner of the application
window, controls the receiver power. When it is off, the receiver circuitry will be
powered down.
When you exit and restart the WiNRADiO G39DDC application, the power
on/off status will be remembered.
Date and Time Display
The top menu bar clock display indicates the current time and date.
Using the function UTC time under Options top menu bar, you can set the
display to be in local time or UTC time.
If in the UTC time mode, the clock will show Universal Coordinated Time,
formerly called GMT (Greenwich Mean Time), which is the standard time used
around the world. This is provided because most shortwave stations announce
their broadcast times in UTC. Both time modes derive their information from
the PC clock. The time difference is determined by a setting in your Windows
Control Panel (Date and Time setting, Time Zone tab).
Did you know?
Coordinated Universal Time is abbreviated “UTC”. The International
Telecommunication Union wanted Coordinated Universal Time to have a single
abbreviation for all languages. English speakers and French speakers each wanted the
initials of their respective language's terms to be used internationally: "CUT" for
"coordinated universal time" and "TUC" for "temps universel coordonné". This resulted
in the final compromise of using "UTC".
