Broadcasting knowledge:

Why is the SW broadcast sound so unstable, continuously changing between 
large and small sound?
The cause can be found in the unstable nature of the ionosphere, which reflects SW 
signals back to earth. The height, thickness and density of the ionosphere influence 
how well SW signals are reflected, but these conditions change constantly, especially 
during daytime. The strength of the signal that is received by the antenna is therefore 
also constantly changing. When listening to SW radio broadcasts, this results in 
sudden changes between large and small sound.

This function is able to remove duplicate 
stations, which is especially useful after 
storing stations manually, as you might 
store a station more than once. It also 
sorts the sequence of all stored stations 
according to frequency. 

Turn off the radio, press and hold the [        ] ( “ ” key ) button on the remote control 
until “            ” blinks in the upper right corner of the LCD; the device is reorganizing 
all stored stations. When completed, the display goes back to showing the alarm 
time in the upper right corner.
