SAVE THIS INSTRUCTION MANUAL — This in- struction manual contains important operating instructions forthe IC-2800H. EXPLICIT DEFINITIONSThe explicit definitions below apply to this instruction manual. CAUTIONSR WARNING! NEVER connect the transceiver to an AC outlet. This may pose a fire hazard or result in an electricshock.R WARNING! NEVER operate the transceiver while dri- ving a vehicle. Safe driving requires your full attention—any-thing less may result in an accident. R WARNING! HIGH VOLTAGE! NEVER disassem- ble the remote controller. There is a high voltage circuit inside. NEVER connect the transceiver to a power source of more than 16 V DC or using reverse polarity. This will ruin the trans-ceiver. NEVER cut the DC power cable between the DC plug and fuse holder. If an incorrect connection is made after cutting,the transceiver may be damaged. NEVER place the transceiver where normal operation of the vehicle may be hindered or where it could cause bodily injury.NEVER let objects impede the operation of the cooling fan on the rear panel. DO NOT push the PTT when not actually desiring to trans- mit. WORD R WARNING CAUTION NOTE DEFINITION Personal injury, fire hazard or electric shock may occur.If disregarded, inconvenience only. No risk of personal injury, fire or electric shock.Equipment damage may occur. Versions of the IC-2800H which display the “CE” symbol on the se-rial number seal comply with the European harmonised standardETS300 684 (EMC product standard for Commercially AvailableAmateur Radio Equipment). ii DO NOT operate the transceiver near unshielded electrical blasting caps or in an explosive atmosphere.During mobile operation, DO NOT operate the transceiver without running the vehicle’s engine. When transceiver poweris ON and your vehicle’s engine is OFF, the vehicle’s batterywill soon become exhausted. AVOID using or placing the transceiver in direct sunlight or in areas with temperatures below –10°C (+14°F) or above+60°C (+140°F). AVOID the use of chemical agents such as benzine or alco- hol when cleaning, as they can damage the transceiver’s sur-faces.Place unit in a secure place to avoid inadvertent use by chil-dren. BE CAREFUL! The transceiver will become hot when op- erating it continuously for long periods. USE Icom microphones only (supplied or optional). Other manufacturer’s microphones have different pin assignmentsand may damage the transceiver if attached. For LCD displayDO NOT press the LCD screen. Excessive pressure may cause permanent damage to the LCD. DO NOT tap or scratch the LCD using sharp objects. BE CAREFUL when cleaning the LCD. Dust can easily scratch the surface.LCDs are produced using high-density manufacturing tech-nology resulting in 99.98% active dots, however, up to 0.02%of the dots may be non-active and/or continuously active. Thisis normal and does not indicate LCD malfunction.Uneven areas may be displayed depending on display con-tents in some cases.After displaying the same screen continuously for long peri-ods, image ‘burn-in’ may occur. In such cases, turn the powerOFF and discontinue operation for at least 24 hours. For U.S.A. onlyCAUTION: Changes or modifications to this device, not ex- pressly approved by Icom Inc., could void your authority tooperate this device under FCC regulations. 1 SUPPLIED ACCESSORIES ......... 12 PANEL DESCRIPTION ......... 2 – 13 n Controller unit ......................... 2 n Function display ...................... 4 n Basic function menu ............... 6 n Main unit ................................. 8 n HM-98 microphone ............... 10 n HM-97/118 microphone ........ 13 3 INSTALLATION ................... 14 – 17 n Location ................................ 14 n Mounting with the mountingbracket .................................. 14 n Mounting the remote controller ............................... 15 n Battery connection ................ 15 n DC power supply connection ............................ 16 n Cable connection .................. 16 n Antenna installation .............. 17 4 FREQUENCY SETTING ...... 18 – 22 n Preparation ........................... 18 n Lock functions ....................... 19 n Using the tuning dial ............. 20 n Using the [ Y ]/[ Z ] keys .......... 20 n Setting a tuning step ............. 21 n Using the keypad .................. 22 5 BASIC OPERATION ............ 23 – 25 n Receiving .............................. 23 n Monitor function .................... 24 n Audio mute function .............. 24 n Transmitting .......................... 24 n Selecting output power ......... 25 n One-touch PTT function ....... 25 6 REPEATER OPERATION .... 26 – 31 n Accessing a repeater ............ 26 n 1750 Hz tone ........................ 28 n Subaudible tone .................... 29 n Offset frequency ................... 30 n Auto repeater function .......... 31 7 MEMORY/CALL CHANNELS ......................... 32 – 39 n General ................................. 32 n Programming during selection................................. 32 n Programming after selection .. 33 n Transferring memory contents to another memory ............... 33 n Programming during selectionvia the microphone ............... 34 n Programming after selection via the microphone ............... 34 n Transferring memory contents to another memory via themicrophone ........................... 35 n Memory clear ........................ 36 n Alphanumeric display ............ 37 n Call channel .......................... 38 8 SCRATCH PAD MEMORY ... 40 – 41 n What is a scratch pad memory? ............................... …

4 - 1 SECTION 4 CIRCUIT DESCRIPTION 4-1 RECEIVER CIRCUITS 4-1-1 DUPLEXER CIRCUIT The transceiver has a duplexer (low-pass and high-pass fil- ters) on the first stage from the antenna connector to sepa- rate the signals into VHF and UHF signals. The low-pass fil- ter (L15, L16, L78, C70–C72) is for VHF signals and the high- pass filter (L44, L45, L82, C189, C190, C493) is for UHF sig- nals. The separated signals are applied to each RF circuit. 4-1-2 VHF ANTENNA SWITCHING CIRCUIT The antenna switching circuit functions as a low-pass filter while receiving. However, its impedance becomes very high while transmitting by turning ON diode (D18). Thus transmit signals are blocked from entering the receiver circuits. The antenna switching circuit employs a 1/4 λtype diode switch- ing system. The passed signals are then applied to the VHF RF amplifier circuit. 4-1-3 VHF SQUELCH ATTENUATOR CIRCUIT The attenuator circuit attenuates the signal strength to a maximum of 10 dB to protect the RF amplifier from distortion when excessively strong signals are received. The current flow of the antenna switching circuit (D18) is con- trolled by the [SQL] control via Q33. When the [SQL] control is rotated clockwise deeper than 12 o’clock, the current of D18 is increased. In this case, D18 acts as an attenuator. 4-1-4 VHF RF CIRCUIT The RF circuit amplifies signals within the range of frequen- cy coverage and filters out-of-band signals. The signals from the antenna switching circuit pass through the tunable bandpass filter (D15, L25, L26, C115–C117). The filtered signals are amplified at the VHF RF amplifier (Q16) and are then enter another 3-stage tunable bandpass filter (D11–D14, L20–L21, C94, C96–C105) to suppress unwant- ed signals. and improve the selectivity. The filtered signals are applied to the VHF 1st mixer circuit (Q15).The tunable bandpass filters (D11–D13, D15) employ varactor diodes to tune the center frequency of the RF passband for wide band- width receiving and good image response rejection. The PLL lock voltage is used for control voltage of these varactor diodes. The PLL lock voltage is amplified at the DC-amplifier (Q18) and then applied to the CPU (IC19, pin 99). The CPU outputs the control signal to the varactor diodes via the D/A converter (IC3). 4-1-5 VHF 1ST MIXER CIRCUIT The 1st mixer circuit converts the received signal to a fixed frequency of the 1st IF signal with a 1st LO (V-VCO output) frequency. The signals from the VHF RF circuit are mixed with the 1st LO signal at the 1st mixer circuit (Q15) to produce a 15.65 MHz 1st IF signal. 4-1-6 VHF 1ST IF CIRCUIT By changing the PLL frequency, only the desired frequency will pass through a pair of crystal filters at the next stage of the mixer. The 1st IF signal from the VHF 1st mixer circuit is applied to a pair of crystal filters (FI1) to suppress out-of-band signals via a matching circuit (R61, C88). The filtered signal is ampli- fied at the IF amplifier (Q40) and is then applied to the VHF 2nd mixer circuit (IC28). 4-1-7 VHF 2ND IF AND DEMODULATOR CIRCUITS The 2nd mixer circuit converts the 1st IF signal to a 2nd IF signal. A double superheterodyne system (which converts receive signals twice) improves the image rejection ratio and obtains stable receiver gain. The FM IF IC (IC28) contains the 2nd local oscillator, 2nd mixer, limiter amplifier, quadrature detector, and noise detec- tor circuits, etc. The 1st IF signal from the 2nd IF amplifier is applied to the 2nd mixer section of IC28 (pin 16), and is mixed with a 15.2 MHz 2nd LO signal generated by the reference oscillator cir- cuit (X1, IC2) to produce a 450 kHz VHF 2nd IF signal. The 2nd IF signal from the 2nd mixer passes through the 2nd IF filter (FI4) (during wide channel spacing selection, or pass- es through FI5 during narrow channel spacing selection; [EUR], [ITA] versions only), where unwanted signals are suppressed. It is then amplified at the limiter amplifier section (IC28, pin 5) and applied to the FM detector section (X2, IC28, pins 10, 11) for demodulation the 2nd IF signal into AF signals. The FM detector circuit employs a quadrature detection method (liner phase detection), which uses a ceramic dis- criminator (X2) for phase delay to obtain a non-adjusting cir- cuit. The detected signal from IC28 (pin 9) is applied to the AF circuit. 4-1-8 VHF AF AMPLIFIER CIRCUIT The AF amplifier circuit amplifies the detected signals to drive a speaker. The AF circuit includes an AF mute circuit for the squelch. AF signals from FM IF IC (IC28, pin 9) pass through the AF selector (IC21, pins 9, 8), and are then applied to the low- pass (Q83, R370–R373, C406–C409) and high-pass (Q84, R375–R379, C415–C418) filters. The filtered signals are level adjusted at the volume control IC (IC10), and are ampli- fied at the AF power amplifier (IC12, pin 2) passing through the V-AF mute switch (Q70). The output signal from IC12 (pin 11) drives the external or internal speaker. 4 - 2 4-1-9 VHF SQUELCH CIRCUIT • NOISE SQUELCH A noise squelch circuit cuts out AF signals when no RF sig- nals are received. By detecting noise components in the AF signals, the squelch circuit switches the AF mute switch. Some of the noise components in the AF signals from the FM IF IC (IC28, pin 9) are passed through the active filter section (IC28, pin 8, 7), and then applied to the noise detector sec- tion (IC28). The variable resister (R196) adjusts the input level of the active filter, and the level is used for squelch threshold reference. The detected noise signals are applied to the CPU (IC19 pin 97) via the “VSQL” line. The [SQL] (CONTROL unit; R154) controls the input level of the sub-CPU (CONTROL unit; IC10, pin 59) in DC voltage. The sub-CPU reads the angle of the [SQL] rotation, then send the squelch data to the CPU incorporated in the RDATA line. Then the CPU controls V-AF mute switch (Q70) via the “VAMUTE” line. Even when the squelch is closed, the V-AF mute switch (Q70) opens at the moment of emittin…
