FM MPX Alignment Dummy Antenna
A. Regular Method
1. Connect a frequency counter to the test point TP8
through 50kQ.
2. Ground the test point TP5. o
3. Adjust the variable resistor VR1 so that the frequency R 1 R -, GC |
becomes 19kHz + 100Hz. 1 |
B. Simplified Method
1. Tune to a FM stereo broadcast. ' |
2. Set the variable resistor VR1 to a center position of the —d
range where the stereo indicator keeps lighting. ™m Mi Bie pa ee te Beh A |
R1+R2= 8002
