- 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 ...

On Windows XP simply adjust the Wave mixer:
To get started, make sure the volume is set approximately as shown above. If
you find that the maximum volume as set on the receiver application panel is
not sufficient, you may then wish to increase the sound card volume later.
Connecting the Antenna
As the old saying goes, “a good antenna is the best amplifier”. No matter how
good a radio receiver is, the performance limit of a radio receiving system is
always determined by the first element of the receiving chain – the antenna.
To make the most out of your WiNRADiO receiver, you should install a good
antenna, preferably located outdoors, as far away as possible from
interference sources. If you are looking for a new antenna, please also check
out the WiNRADiO antenna product range at www.winradio.com/antennas.
The specifics of a computer-based receiver may often require careful
consideration with respect to the antenna connection and installation, to make
sure that computer-generated noise does not enter the receiver’s antenna
input.
