INSTRUCTION MANUAL COMMUNICATIONS RECEIVER iR75 i IMPORTANT READ THIS INSTRUCTION MANUAL CAREFULLYbefore attempting to operate the re- ceiver. SAVE THIS INSTRUCTION MANUAL.This manual contains important safety and operating in- structions for the IC-R75. EXPLICIT DEFINITIONS RNEVERapply AC to the [DC13.8V] jack on the re- ceiver rear panel. This could cause a fire or ruin the re- ceiver. RNEVERapply more than 16 V DC, such as a 24 V battery, to the [DC13.8V] jack on the receiver rear panel. This could cause a fire or ruin the receiver. RNEVERlet metal, wire or other objects touch any internal part or connectors on the rear panel of the re- ceiver. This may result in an electric shock. NEVERexpose the receiver to rain, snow or any liq- uids. AVOIDusing or placing the receiver in areas with tem- peratures below –10°C (+14°F) or above +60°C (+140°F). Be aware that temperatures on a vehicle’s dashboard can exceed 80°C (+176°F), resulting in per- manent damage to the receiver if left there for ex- tended periods. AVOIDplacing the receiver in excessively dusty envi- ronments or in direct sunlight. AVOIDplacing the receiver against walls or putting anything on top of the receiver. This will obstruct heat dissipation. Place unit in a secure place to avoid inadvertent use by chil- dren. During mobile operation, DO NOToperate the receiver without running the vehicle’s engine. When receiver power is ON and your vehicle’s engine is OFF, the ve- hicle’s battery will soon become exhausted. Make sure the receiver power is OFF before starting the vehicle. This will avoid possible damage to the re- ceiver by ignition voltage spikes. The receiver comes with the following accessories.

IC-R75 CIRCUIT DESCRIPTION 3 - 1 3-1 RECEIVER CIRCUITS 3-1-1 RF SWITCHING CIRCUIT (MAIN UNIT) The IC-R75 has two antenna connectors. RF signals enter either the [50 ΩANT.] or [450 ΩANT.] connector. RF signals from the [50 ΩANT.] connector are applied to the antenna switching circuit (RL121), and then pass through the low-pass filter (L131, L132, C131–C136). RF signals from the [450 ΩANT.] connector are passed through the L101 to exchange the impeadance value, and are then applied to the antenna switching circuit (RL121). The signals are applied to the low-pass filter (L131, L132, C131–C136). Each RF signals from the [50 ΩANT.] connector or [450 Ω ANT.] connector are chosen by the antenna switching circuit (RL121). 3-1-2 RF FILTER CIRCUIT (MAIN UNIT) The filtered signals are applied to the RX attenuator switch- ing circuit (RL141). Either the signals bypass or pass through the attenuator circuit. The signals are attenuated at 20 dB when passing through the attenuators. The attenuator sys- tem excludes non-linear components between an antenna connector and an attenuator to prevent strong signals from causing distortion. The signals are then applied to the RF fil- ters. The MAIN UNIT has 8 RF bandpass fileters for signals above 2.0 MHz and 2 low-pass filters for signals below 2.0 MHz. (1) Below 1.6 MHz The signals are applied to the low-pass filter consisting of C170–C175, L171–L173 via the limitter circuit (D141, D142). A diode is removed at the entrance of the low-pass filter. This device prevents the diode from causing distortion when receiving very strong signals. A switching diode (D172) is turned on when the “B0” line is “HIGH”. (2) Above 1.6 MHz The signals are applied to the high-pass filter consisting of C161–C163, L161–L164. This filter suppresses strong sig- nals below 1.6 MHz such as broadcasting stations. The filtered signal between 1.6 MHz and 2.0 MHz are applied to the low-pass filter (C182–C187, L182, L183) via the switching diode (D181). The switching diodes (D181, D182) are turned ON when the “B1” line is “HIGH”. The filtered signals above 2.0 MHz are applied to one of 8 bandpass filters depending on the receive frequencies. After passing through a bandpass or low-pass filter, the sig- nals are applied to the pre-amplifier circuit (Q381, Q382, IC391). (3) FILTER SWITCHING CIRCUIT The RF bandpass filter corresponds to the BPF switching voltage (B0–B9) based on the CPU via the shifit registor (IC551, IC552) and driver (IC561, IC562). The switching volt- age of the BPF exit ot improve multi-signal and strong signal characteristics. 3-1-3 PRE-AMPLIFIER CIRCUIT (MAIN UNIT) The pre-amplifier circuit uses low noise junction FETs (Q381, Q382) or wideband amplifier (IC391) to provide gain over a wide frequency range. When the [P.AMP] switch is turned “PREAMP 1”, the signals from the RF filter are amplified by the junction FETs pre- amplifier circuit (Q381, Q382). When the [P.AMP] switch is turned “PREAMP 2”, the signals from the RF filter are amplified by the wideband pre-amplifi- er circuit (IC391). When the [P.AMP] switch is turned “PREAMP OFF”, the sig- nals from the RF filter bypass the pre-amplifiers through D371 and D372. The amplified or bypassed signals are applied to the 1st mixer circuit (Q441, Q442) via the low-pass filter (L431, L432 and C431–CC436). The low-pass filter attenuates at 50 MHz to suppress image frequency. 3-1-4 1ST MIXER AND IF CIRCUITS (MAIN UNIT) The filtered signals are mixed with a 69.0415–129.0115 MHz 1st LO signal to produce a 69.01 MHz 1st IF signal at the 1st mixer circuit (Q441, Q442). The 1st mixer circuit employs a balanced mixer using low- noise junction FETs (Q441, Q442) to expand the dynamic range. The 69.0415–129.0115 MHz 1st LO signal is applied to an LO amplifier (Q411) from the PLL unit via J411, and then passes through the low-pass filter (L421, L422, C422–C425). The filtered signal is applied to the 1st mixer circuit. The 1st IF signal is applied to the crystal bandpass filter(FI- 461) to suppress out-of-band signals. The filtered signal is amplified at a 1st IF amplifier (Q471), and then applied to a 2nd mixer circuit (D491) 3-1-5 2ND MIXER AND IF CIRCUITS (MAIN UNIT) The 1st IF signal is mixed with a 60.0 MHz 2nd LO signal to produce 9 MHz 2nd IF signal at the 2nd mixer (D491, C492, L491, L492). The 6.0 MHz 2nd LO signal is applied to the 2nd mixer from the PLL unit via J491. The 9 MHz 2nd IF signal is applied to the crystal bandpass filter (FI701) to suppress unwanted signals. 3 - 2 The filtered signal enters the noise blanker gate (D711–D714). The signal is applied to L712 to obtain clear reception and is then amplified at the 2nd IF amplifier (Q721). The signal passes through a loose resonator circuit (C726, L721) and then is applied to one of the two crystal bandpass filters. When the [FIL] switch is turned “2F3K”, the filter is selected FI761 which covering the 2.4 kHz bandwith. When the [FIL] switch is turned “2FOP”, the filter is selected an optional filter. When the [FIL] switch is turned “2FTH”, the signal from the 2nd IF amplifier bypass the crystal bandpass filters through D771 and D773. The filtered or bypassed signal is amplified at the buffer amplifier (Q801) and applied to the 3rd mixer circuit (IC811). 3-1-6 NOISE BLANKER CIRCUITS (MAIN UNIT) The IC-R75 uses a trigger noise blanker circuit which removes pulse-type noise signals at the noise blanker gate (D711–D714). The 2nd IF signal passes through the crystal bandpass filter (FI701) to suppress unwanted signals. A portion of the output signal is applied to a noise amplifier circuit (IC731, Q731, Q733) and detected at a noise detector circuit (D731). The detected voltage is applied to a noise blanker gate control cir- cuit (Q735–Q737, D732). The threshold level of the noise blanker gate control circuit (Q735–Q737, D732) is set at 1.0 V on SSB mode (In case of AM mode, is set at 1.6 V). When the detected voltage exceeds the threshold level, Q737 outputs a blanking signa…
