Audio output from the transceiver

•   Connect to the audio input of the TNC, MCP, or PC (or PC 

interface connection).

•   Audio output level is independent from the AF control setting.
•   Audio output level can be changed by adjusting the value in 

Menu No. 74.  Set the value to a moderate audio output level.  
The default value of 4 is approximately 0.5 V

p-p

, which is a 

standard modulating signal.  The settings of 0 ~ 9 vary from 
approximately 0 V
