SERVICE MANUAL MF/HF MARINE TRANSCEIVER iM802
INTRODUCTION DANGER This service manual describes the latest service information for the IC-M802 MF/HF MARINE TRANSCEIVER at the time of publication. NEVER connect the transceiver to an AC outlet or to a DC power supply that uses more than 16 V. This will ruin the transceiver. DO NOT expose the transceiver to rain, snow or any liquids. MODEL VERSION SYMBOL U.S.A. USA Canada CAN Other OTH IC-M802 DO NOT reverse the polarities of the power supply when connecting the transceiver.

SECTION 3 CIRCUIT DESCRIPTION The IF amplifier (Q203) and resonator circuits are designed between the filter pair. The PLL output signal (1LO) enters the MAIN unit via the J601 and is amplified at the 1st LO amplifier (Q601). The amplified signal is passed through the 100 MHz cut-off low-pass filter (L604, L605, C604, C606–C610) to suppress harmonics components, and then applied to the 1st mixer circuit (Q201, Q202).
The level-shifted signal is applied to the DSP IC (IC301) for the digital IF filter, demodulator, automatic notch and noise reduction, etc. When receiving strong signals, the detected voltage increases and the AGC1 voltage decreases. As the AGC1 voltage is used for the bias voltage of the IF amplifiers (MAIN unit; Q203, Q401, Q501), IF amplifier gain is decreased. The output signal from the DSP IC is applied to the D/A converter section in the CODEC IC (IC501) to convert into the analog audio signals.
When the speech compressor function is ON, the level-shifted signal from the CODEC IC (IC501) is applied to the DSP IC (IC301) and compressed at the DSP IC to obtain an average audio level. 3-2 TRANSMITTER CIRCUITS 3-2-1 MICROPHONE AMPLIFIER CIRCUIT (RC-25, MAIN AND DSP UNITS) The microphone amplifier circuit amplifies microphone audio signal to a level needed for the DSP circuit.
• 2–2.9999 MHz signal The signal is applied to the relay (FILTER unit; RL7061) which is controlled by the band control IC (MAIN unit; IC3602) as the “L2M” signal via the buffer amplifier (MAIN unit; IC1301, pin 12). The signal passes through the lowpass filter (FILTER unit; L7066–L7068, C7063–C7084, C7086, C7087), and then applied to the RL7062. 3-2-5 RF CIRCUIT (MAIN, PA UNITS AND DRIVER BOARD) The RF circuit amplifies operating (transmitting) frequency to obtain 150 W of RF output.
• 14–19.9999 MHz signal The signal is applied to the relay (FILTER unit; RL7211) which is controlled by the band control IC (MAIN unit; IC3602) as the “L16M” signal via the buffer amplifier (MAIN unit; IC1301, pin 17). The signal passes through the lowpass filter (FILTER unit; L7216–L7218, C7214, C7216, C7217, C7221–C7225), and then applied to the RL7212. • SWR APC CIRCUIT (FILTER AND MAIN UNITS) The reflected wave signal appears and increases on the antenna connector.
The detected signal output from the PLL IC (pin 2) is converted into a DC voltage (lock voltage) at the loop filter and then fed back to one of the VCO circuits (Q5521, D5521, L5523). 3-3 PLL CIRCUITS 3-3-1 GENERAL The PLL circuits generate a reference frequency (32.000 MHz); 1st LO frequencies (64.485–94.455 MHz); 2nd LO frequency (64 MHz), 3rd LO frequency (433.000 kHz).
The 1st IF signal from the 1st IF amplifiers is applied to the 2nd mixer IC (IC2701, pin 3), and is mixed with the 2nd LO signal to the converted into a 12 kHz 2nd IF signal. 3-4 DSC CIRCUITS ([USA], [CAN] ONLY) 3-4-1 DSC BANDPASS FILTER AND RF AMPLIFIER CIRCUITS (MAIN UNIT) The RF circuit filters out-of-band signals and amplifiers signals within the range of frequency coverage.
