Overview
AM: RF amplifier, mixer, oscillator (with ALC), IF amplifier, detector, AGC, oscillator buffer, tuning indicator (narrow-band SD), IF buffer output, IF output for AM stereo

• FM IF: IF amplifier, quadrature detector, band muting, tuning indicator, IF buffer output, S-meter
• MPX: PLL stereo decoder, stereo indicator, forced mono, VCO stop function, adjacent channel interference rejection function (114 kHz), post-amplifier (with muting function)

Features
• Reduced number of adjustments (adjustment-free MPX VCO: ceramic resonator adopted)
• Tuning indicator pin (Can be used as a narrow-band stop signal and as a muting output driver.)
• Variable FM stop sensitivity and band
• Variable AM stop sensitivity
• Built-in AM local oscillator buffer
• Variable AM low cut control
