Motorola MC1310 phase-locked loop stereo decoder requires only one adjustment, by 5K pot R5. With pin 2 open, adjust R5 until reading of 19.00 kHz is obtained with frequency counter at pin 10. Alternatively, tune to stereo broadcast and adjust R5 to center of lock-in range of stereo pilot lamp. Circuit gives 40-dB separation and about 0.3% total harmonic distortion.-B.
