RADIO TUNING  
 
1.0 Introduction 
This chapter provides an overview of the hardware tuning for this Mag One™ Series radio. There is no 
software tuning required.  
In  order  to  perform  the  manual  tuning  procedures,  the  radio  needs  to  be  disassembled  to  the  PC 
Board.  
 
Following are the parameters that can be tuned:- 
1. Transmitter Tuning 
a.    High Power Tuning 
b.    Low Power Tuning 
c. Frequency Tuning 
d.    Modulation Balancing 
e.    Maximum...

Improperly tuned modulation balance can cause errors in Tx sub-tone modulation.   

 
 
 
 
 
3-6 Hardware Tuning Setup and Procedure 
 
2.3.5 Maximum Modulation 
1. Set the radio to the appropriate tuning frequency (refer to Table 3-1). 
2. On the test equipment, set the following configurations: 
Audio bandwidth: 0.25Hz to 15,000Hz 
De-emphasis: Off 
FM: Peak negative 
3. Using the Audio Analyzer, input a 1kHz tone + 67Hz subtone, 120mV to the radio through the 
test box. 
4. Key up the radio. 
5. Using the ceramic tool, adjust R159 to tune maximum modulation between 2.4 ± 0.02KHz for...
