WiNRADiO G3XX VHF/UHF Receiver 
 
 
The Avg button, when activated, shows the S-meter level value as a floating 
average within the preset time interval (settable from 1 to 99 seconds). This is 
used to smooth the S-meter movements. Any change which may affect the 
S-meter value (such as tuning the receiver to a new frequency or changing the 
attenuator setting), resets the averaging interval, so that the S-meter may 
react immediately to such change. 
Note: The S-meter relies on the AGC for its proper operation. Therefore, if the 
AGC is switched off and manual IF gain is used instead, the S-meter is also 
disabled. 
 
Did you know? 
There are no exact definitions for S-units, merely recommendations. 
Historically, the S-units referred to subjectively perceived signal strength as 
follows:  
S1… faint signals, barely perceptible  
S2… very weak signals  
S3… weak signals  
S4… fair signals  
S5… fairly good signals  
S6… good signals  
S7 …moderately strong signals  
S8 …strong signals  
S9… extremely strong signals
