4-1-4 1ST IF AND 2ND MIXER CIRCUITS (RF UNIT)
The 2nd mixer circuit converts the 1st IF signal to a 2nd IF signal. The filtered each 1st IF signal from the bandpass filter are mixed with the 2nd LO signal at the 2nd mixer circuit (IC10, pin 1) to produce each 2nd IF signal depending on the receiving frequency. In AM and FM mode, the 2nd IF signal (26.5 MHz) passes through the band switching diode (D71) and bandpass filter (FI3). The filtered signals are then amplified at the 2nd IF amplifier (Q41), and are applied to the demodulator circuit. In WFM mode, the 2nd IF signal (13.25 MHz) passes through the band switching diode (D72) and bandpass filter (FI4). The filtered signal is then amplified at the 2nd IF amplifier (Q41), and is applied to the demodulator circuit. In TV mode, the 2nd IF signal (58.75 MHz) passes through the band switching diode (D901) and is then applied to the 2nd IF amplifier (Q857). The amplified signal passes through the bandpass filter (FI901), and is applied to the demodulator circuit.

AM MODE The 3rd IF signal is output from FM IF IC (IC2, pin 3) and passes through the ceramic bandpass filter (FI2). The filtered signal is applied to the AM detector circuit (Q44, Q45) to convert into AF signals, and the signals are applied to the AF circuit (LOGIC unit). FM MODE The 3rd IF signal is output from FM IF IC (IC2, pin 3) and passes through the ceramic bandpass filter (FI2). The filtered signal is fed back and amplified at the limiter amplifier section (pin 5), then demodulated AF signals at the quadrature detector section (pins 10, 11) with detector coil (L21). The demodulated AF signals are output from pin 9 and are applied to the AF circuit (LOGIC unit). WFM MODE The 3rd IF signal from the 3rd mixer bypasses the ceramic filter (FI2) and fed back to the limiter amplifier section (pin 5). The amplified signal is demodulated at the quadrature detector section (pins 10, 11) with detector coil (L21). The AF signals are output from pin 9 and are applied to the AF circuit (LOGIC unit). By connecting R55 to R54 in parallel, the output characteristics of pin 12, "RSSI", change gradually. Therefore, the FM IF IC can detect WFM components.

4-1-5 DEMODULATOR CIRCUITS (RF UNIT)
The demodulator circuit converts the 2nd IF signal into AF signals or video signals. (1) AM, FM AND WFM MODE The each 2nd IF signals from the 2nd IF amplifier (Q41) are applied to the 3rd mixer section of the FM IF IC (IC2, pin 16) and are then mixed with the 3rd LO signal for conversion into a 450 kHz 3rd IF signal.

(2) TV MODE The amplifed signals at the 2nd IF amplifier (Q857) are applied to the bandpass filter (FI901). The filtered signals are applied to the TV IF IC (IC901) as audio IF signal and the video IF signal, separately. IC901 is the video/audio detector IC of the PLL sprit type, which contains the video IF amplifier, PLL video detector, voice IF detector, IF and RF AGC, etc. The audio IF signal from FI901 (pin 3) is applied to the TV IF IC (IC901, pin 9) as the "SIF" signal, and is amplified and phase detected in the IC. The phase detected signal is output from pin 15, and is fed back to pin 13 via FI902. The filtered signal is applied to the limitter amplifier section and FM detector section in the TV IF IC. The demodulated AF signals are output from pin 12 and are applied to the AF circuit (LOGIC unit). The video IF signal from FI901 (pin 4, 5) is applied to the TV IF IC (IC901, pin 4, 5) as "VIF" signal, and is then amplified at the video IF amplifier in the TV IF IC. The amplified signal is compared with the VCO frequency (L902, C906), and is then applied to the phase detector section in the TV IF IC. The detected signal is output from pin 22 as the video signal, and then passed through the bandpass filter (FI905). The filtered signal is amplified at Q854, and applied to the buffer amplifier (Q855). The amplified signal is applied to the TFT LCD circuit (LOGIC unit).

While in WFM mode, AF signals ("WFM" signal) are applied to the pre-amplifier (Q31) directly. The pre-amplified AF signals pass through the AF mute circuit (Q37) and are then applied to the electronic volume control circuit (IC14, pin 6). The level controlled AF signals are output from pin 7 and applied to the AF power amplifier (IC15, pin 1) via the buffer amplifier (Q36). The power amplified AF signals are applied to the internal speaker via the [EXT SP] jack. The electronic volume control circuit controls AF gain, therefore, the AF output level is according to the [VOL] setting and also the squelch conditions. The AF mute and electronic volume control circuits are controlled by CPU (IC11) via each "AMUTE" and "VRC" signal lines. When connecting [A/V OUT] jack (RF unit; J3) on TV mode, AF signals from demodulator circuit (RF unit; IC901, pin 12) are applied to the [A/V OUT] jack directly. On AM, FM, WFM mode, AF signals from demodulator circuit (RF unit; IC2, pin 9) are applied to the RF amplifier (FMTV unit; Q71) via J5 (pin 1) on RF unit. The amplified signals are applied to the [A/V OUT] jack via the J7 (pin 3).

The OSD IC produces LCD screen display data, and then outputs video signals to the TFT driver (IC901). The TFT driver contains the procesing of RGB signal circuit, color control circuit, etc. The TFT driver controls the TFT LCD (DS4) using the video signals from the OSC IC.

4-1-6 AF AMPLIFIER CIRCUIT (LOGIC UNIT)
The AF amplifier circuit amplifies the demodulated AF signals to drive a speaker. While in FM and TV mode, AF signals ("FMAF" signal) from the demodulator circuit (RF unit) are passed through the deemphasis circuit (R118, C66, C68) with frequency characteristics of 6 dB/octave, and are then applied to the preamplifier (Q31) via the bandpass filter (Q30). While in AM mode, AF signals ("AMAF" signal) are pass through the bandpass filter (Q30) and are then applied to the pre-amplifier (Q31).

4-1-8 SQUELCH CIRCUIT (LOGIC AND RF UNITS)
NOISE SQUELCH The noise squelch circuit cuts out AF signals when no RF signals are received. By detecting noise components in the AF signals, the squelch circuit switches the AF mute switch.

A portion of the AF signals from the FM IF IC (RF unit; IC2, pin 9) are applied to the active filter section (IC2, pin 8). The active filter section amplifies and filters noise components. The filtered signals are applied to the noise detector section and output from pin 13 as the "SDET" signal. The "SDET" signal from IC2 (pin 13) is applied to the CPU (LOGIC unit; IC11, pin 12) directly. The CPU analyzes the noise condition and outputs the "AMUTE" signal to the AF mute switch (Q37). Even when the squelch is closed, the AF mute switch (Q37) opens at the moment of emitting beep tones. TONE SQUELCH The tone squelch circuit detects AF signals and opens the squelch only when receiving a signal containing a matching subaudible tone (CTCSS). When tone squelch is in use, and a signal with a mismatched or no subaudible tone is received, the tone squelch circuit mutes the AF signals even when noise squelch is open.

A portion of the AF signals from the FM IF IC (RF unit; IC2, pin 9) passes through the low-pass filter (LOGIC unit; IC9) via the "FMAF" signal to remove AF (voice) signals and passes through the tone filter (LOGIC unit; IC9, Q8). The filtered signal is applied to the CTCSS decoder inside CPU (LOGIC unit; IC11, pin 8) via the "RTONE" line to control the AF mute switch.
