• Connecting Level Meter (FM and AM)
• Connecting Digital Voltmeter (FM and AM)
• Repeat the procedures in each adjustment several times, and the
frequency coverage and tracking adjustments should be finally
done by the trimmer capacitors.
• For FM adjustment, fix the FM RF coil (L1) as shown next page
and then perform tracking adjustment at L2 and CT1.
Lastly check the voltage value.
• For AM adjustment, fix the ferrite-rod antenna (L3) as shown
next page and then perform tracking adjustment at L4 and CT3.
Lastly check the voltage value.
