The IC-M1V VHF MARINE TRANSCEIVER is designed and built with Icom’s superi- or technology and craftsmanship. With proper care this prod-uct should provide you with years of trouble-free operation. IMPORTANTREAD ALL INSTRUCTIONS carefully and completely before using the transceiver. SAVE THIS INSTRUCTION MANUAL— This instruction manual contains important operating instructionsfor the IC-M1V. EXPLICIT DEFINITIONS CAUTIONSR WARNING! NEVER connect the transceiver to an AC outlet. This may pose a fire hazard or result in an electricshock. R WARNING! NEVER hold the transceiver so that the antenna is very close to, or touching exposed parts of thebody, especially the face or eyes, while transmitting. Thetransceiver will perform best if the microphone is 5 to 10 cm(2 to 4 in) away from the lips and the transceiver is vertical. NEVER connect the transceiver to a power source other than the BP-215. Such a connection will ruin the transceiver.NEVER charge battery packs except in the methods described in this manual. AVOID using or placing the transceiver in areas with tem- peratures below –20°C (–4°F) or above +60°C (+140°F). AVOID the use of chemical agents such as benzine or alco- hol when cleaning, as they may damage the transceiver sur-faces. After exposure to saltwater, clean the transceiver thor-oughly with fresh water to avoid corrosion. BE CAREFUL! The transceiver rear panel will become hot when operating continuously for long periods. i WORD DEFINITION R WARNING! CAUTION NOTE Personal injury, fire hazard or electric shockmay occur.Equipment damage may occur.It desired, inconvenience only. No risk ofpersonal injury, fire or electric shock. BE CAREFUL! The IC-M1V employs waterproof con- struction, which corresponds to JIS waterproof specification,grade 7 (1 m/30 min.). However, once the transceiver hasbeen dropped, it is not guaranteed due to the transceiver maybe cracked, or waterproof seal damaged, etc. MAKE SURE the flexible antenna and battery pack are securely attached to the transceiver and that the antenna andbattery pack are dry before attachment.

IC-M1V CIRCUIT DESCRIPTION 3 - 1 1-1RECEIVER CIRCUITS 1-1-1ANTENNA SWITCHING CIRCUIT (RF UNIT) The antenna switching circuit functions as a low-pass filter while receiving and as resonator circuit while transmitting. The circuit does not allow transmit signals to enter receiver circuits. Received signals from the antenna connector pass through the low-pass fileter (L15–L17, C72–C77), and then the antenna switching circuit (D9, D11, D12). The filtered signals are then applied to the RF amplifier (Q13). 1-1-2RF AND 1ST MIXER CIRCUITS (RF UNIT) The 1st mixer circuit converts the received signals to a fixed frequency of the 1st IF signal with a PLL output frequency. By changing the PLL frequency, only the desired frequency will be passed through a pair of crystal filters at the next stage of the 1st mixer. The signals from the antenna switching circuit are passed through the tunable bandpass filter (D13, D14) and amplified at the RF amplifier (Q13). The amplified signals are passed through another tunable bandpass fileter (D15–D18), and then applied to the 1st mixer circuit (Q14). The filtered signals are mixed at the 1st mixer (Q3) with a 1st LO signal coming from the PLL circuit to produce a 21.7 MHz 1st IF signal. The 1st IF signal is passed through a pair of crystal filters (FI1,FI2) and is then amplified at the IF amplifier (Q15). 1-1-32ND IF AND DEMODULATOR CIRCUITS (MAIN AND RF UNITS) The 2nd mixer circuit converts the 1st IF signal to a 2nd IF signal. A double convertion superheterodyne system (which converts receive signal twice) improves the image rejection and obtain stable receiver gain. The 1st IF signal is applied to a 2nd mixer section of the FM IF IC (MAIN unit; IC2, pin 16). The signal is then mixed with a 2nd LO signal for conversion to a 450 kHz 2nd IF signal. IC1 contains the 2nd mixer, limiter amplifier, quadrature detector and active filter circuits. A 21.25 MHz 2nd LO signal is produced at the PLL circuit by dividing it’s reference fre- quency. The 2nd IF signal from the 2nd mixer (MAIN unit; IC1, pin 3) passes through a ceramic filter (MAIN unit; FI1 and FI2) to remove unwanted heterodyned frequencies. It is then ampli- fied at the limiter amplifier (MAIN unit; IC1, pin 5) and applied to the quadrature detector (MAIN unit; IC1, pin 10 and 11) to demodulate the 2nd IF signal into AF signals. 1-1-4AF CIRCUIT (MAIN UNIT) AF signals from the FM IF IC (IC1, pin 9) are fed to the optional voice scrambler unit to demodulate scrambled audio or are bypassed around the unit via the analog switch (IC5). The AF signals (detected signals) are passed through the analog switch (IC5, pin 8) and are then applied to the active low-pass filter (IC4, pin 9 and 10). The filtered AF signals are passed through the [VOL] control (VR unit; R1) and then another analog switch (IC3, Q3). The passed signals are applied to the AF power amplifier (IC2). 1-1-5SQUELCH CIRCUIT (MAIN UNIT) • 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 (IC1, pin 9) are applied to the active filter section (IC1, pin 8). The active fil- ter section amplifies and filters noise components. The fil- tered signals are applied to the noise detector section and output from IC1 (pin 12) as the “SD” signal. The “SD” signal from IC2 (pin 12) is applied to the CPU (IC9, pin 98) to analyze the noise condition, and then outputs the “BEEP” signal from the CPU (IC9, pin 78) to low-pass filter (IC4, pin 10). The filtered signal is passed through the analog switch, and then applied to the AF amplifier (IC2). The amplified AF sig- nal is output to the internal speaker or the external speaker jack. • 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 (IC1, pin 9) passes through the low-pass filter (IC4) via the analog swtich (IC5) to remove AF (voice) signals and is applied to the CTCSS decoder inside the CPU (MAIN unit; IC9, pin 97) via the “TONE” line to control the AF mute switch. 3 - 2 1-2TRANSMITTER CIRCUITS 1-2-1MICROPHONE AMPLIFIER CIRCUIT (MAIN UNIT) The microphone amplifier circuit amplifies audio signals with +6 dB/octave pre-emphasis characteristics from the micr- phone to a level needed for the modulation circuit. The AF signals from the microphone are passed through the pre-emphasis circuit (R31, C36) and are then applied to the microphone amplifier (IC4, pin 13). The amplified AF signals are applied to the optional voice scrambler unit to scramble the audio via the “MICOUT” signal, or are bypassed around the unit via an analog switch (IC5, pin 4). The amplified AF signals are amplified again at the limiter- amplifier (IC4, pin 2) and then applied to the low-pass filter (IC4, pin 6). The filtered audio is applied to the RF unit as the “MOD” signal. 1-2-2MODULATION CIRCUIT (RF UNIT) The modulation circuit modulates the VCO oscillating signal (RF signal) using the microphone audio signals. The audio signals (MOD) change the reactance of D4 to modulate an oscillated signal at the transmitter VCO (Q4, Q5). The oscillated signal is amplified at the buffer-amplifiers (Q6, Q8). 1-2-3DRIVE/POWER AMPLIFIER CIRCUITS (RF UNIT) The signal from the VCO circuit passes through the trans- mit/receive switching circuit (D7, D8) and is applied to the buffer-amplifier (Q9). The amplified signal is amplified by the pre-driver (Q10) and the power amplifier (Q11) to obtain 5W of RF power (at 7.4 V). The amplified signal passes through the antenna switching circuit (D9), and low-pass filter (C72–C77, L15–L17) and is then applied to the antenn…
