SERVICE MANUAL
COMMUNICATIONS RECEIVER
INTRODUCTION
This service manual describes the latest service information for the IC-R3 at the time of publication. To upgrade quality, all electrical or mechanical parts and internal circuits are subject to change without notice or obligation.
DANGER
NEVER connect the receiver to an AC outlet or to a DC power supply that uses more than 16 V. Such a connection could cause a fire hazard and/or electric shock. DO NOT expose the receiver to rain, snow or any liquids. DO NOT reverse the polarities of the power supply when connecting the receiver. DO NOT apply an RF signal of more than 20 dBm (100mW) to the antenna connector. This could damage the receiver's front end.
ORDERING PARTS

REPAIR NOTES
1. 2. 3. 4. 5. 6. Make sure a problem is internal before disassembling the receiver. DO NOT open the receiver until the receiver is disconnected from its power source. DO NOT force any of the variable components. Turn them slowly and smoothly. DO NOT short any circuits or electronic parts. An insulated turning tool MUST be used for all adjustments. DO NOT keep power ON for a long time when the receiver is defective. READ the instructions of test equipment thoroughly before connecting equipment to the receiver.

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.

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.

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).
