RADIO TUNING
1.0 Introduction
This chapter provides an overview of the hardware tuning for this Mag One by Motorola 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 Modulation
f. Subtone Modulation
2.Receiver Tuning 
a....

3-2Hardware Tuning Setup and Procedure
2.0 Hardware Tuning Setup and Procedure
2.1 Tuning Frequency
2.2 Preparation Before Tuning (refer to Figure 3-1)
1.Set Power Supply to 7.5V and then connect to the radio.
2.Connect the connector and ground plate to the radio antenna port.
3.Connect the radio to the test equipment.
Table 3-1   Frequencies Used for Tuning.

Hardware Tuning Setup and Procedure3-3
2.3 Transmitter Tuning 
2.3.1 High Power
1.Connect the radio to power meter. 
2.Set the radio to the appropriate tuning frequency (refer to Table 3-1).
3.Key up the radio.
4.Using the ceramic tool, adjust R425 to tune high power (refer to Figure 3-2).
2.3.2 Low Power
1.Connect the radio to power meter. 
2.Set the radio to the appropriate tuning frequency (refer to Table 3-1).
3.Key up the radio.
4.Using the ceramic tool, adjust R426 to tune low power (refer to...

3-4Hardware Tuning Setup and Procedure
6.Using the ceramic tool, adjust R174 to tune to 100% of the maximum deviation (refer to 
Figure 3-3).  
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 1 kHz tone + 67Hz subtone, 120mV to the radio through the 
test box.
4.Key up the radio. 
5.Using...
