Page 11 (1,1)
Talk Range The IC-4088E is designed to maximize performance and improve transmission range in the eld. However, the single most important factor in transmit range (talk power) is the surrounding environment. These radios are line of sight radios and as such, transmission range are influenced by the degree to which you can see the other communicating party. Large concrete structures and heavy foliage or transmission from inside a building or vehicle will reduce the talk power range. Optimal range: wide, open areas free of obstructions. Medium range: large buildings or trees blocking your line of sight. Minimum range: mountainous areas or areas of heavy foliage.
Page 12 (1,1)
I Setting the group code
The IC-4088E is equipped with 38 group codes. Group mode operation provides communication with silent standby since you will only receive calls from group members using the same group number. First of all, set the same group code number for all group members transceivers. To turn ON the group mode operation: q Push [MODE] to enter set mode.

What is CTCSS (Continuous Tone Coded Squelch System) GROUP MODE ? CTCSS (Continuous Tone Coded Squelch System) GROUP MODE allows communication with silent stand by. Only signals containing a specic group code can open the squelch. This conveniently eliminates unwanted audio and is useful in group activities or security related activities where unwanted output can be a problem. Note that CTCSS group mode is not privateanyone can receive your calls. The IC-4088E is equipped with 38 tone codes for CTCSS GROUP MODE use. Selecting a code applies it to all 69 operating channels. Each push of [PTT] superimposes your group code over your transmit signal; and, only signals containing the same code can open your squelch. To temporarily hear all signals (including noise) push and hold [MODE]. Do not use CTCSS GROUP MODE if you want to be able to hear signals on all channels.

4-1-4 2ND MIXER AND DEMODULATOR CIRCUITS (RF UNIT)
The 2nd mixer circuit converts the 1st IF signal to a 2nd IF signal. A double conversion superheterodyne system (which converts receive signals twice) improves the image rejection ratio and obtains stable receiver gain. The 1st IF signal from the IF amplifier (Q3) is applied to the 2nd mixer section in the FM IF IC (IC1, pin 16), and is mixed with the 2nd LO signal to be converted into a 450 kHz 2nd IF signal. The FM IF IC contains a 2nd mixer, quadrature detector, noise amplifier and a limiter amplifier, etc. The PLL reference oscillator (X2) is used for the 2nd LO signal via the PLL IC (IC2, pins 11, 9), and is applied to pin 1 of the FM IF IC (IC1). The mixed 2nd IF signal is output from pin 3 and passed through the ceramic bandpass filter (FI3) to remove unwanted heterodyne frequencies. It is then amplified at the limiter amplifier section (IC1, pin 5) and applied to the quadrature detector section (IC1, pins 10, 11) to demodulate the 2nd IF signal into AF signals.
4-1 RECEIVER CIRCUITS
4-1-1 ANTENNA SWITCHING CIRCUIT (RF UNIT)
Received signals from the antenna connector are passed through the low-pass filter (L1L3, C1C5). The filtered signals are applied to the 4 type antenna switching circuit (D1 -D4, L5, L6, C9, C10). The antenna switching circuit functions as a low-pass filter while receiving. However, its impedance becomes very high while D101 and D102 are turned ON (while transmitting). Thus transmit signals are blocked from entering the receiver circuits. The passed signals are then applied to the RF amplifier circuit.
4-1-2 RF CIRCUIT (RF UNIT)
The RF circuit amplifies signals within the range of frequency coverage and filters out-of-band signals. The signals from the antenna switching circuit are amplified at the RF amplifier (Q1) and passed through the bandpass filter (FI1) to suppress out-of-band signals. The filtered signals are applied to the 1st mixer circuit (Q2).
4-1-5 AF CIRCUIT (RF AND MAIN UNITS) 4-1-3 1ST MIXER AND 1ST IF 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 desired signals will be passed through a crystal filter at the next stage of the 1st mixer. The signals from the bandpass filter are mixed at the 1st mixer circuit (Q2) with a 1st LO signal coming from the VCO circuit to produce a 21.7 MHz 1st IF signal. The 1st IF signal is applied to a crystal filter (FI2) to suppress out-of-band signals. The filtered 1st IF signal is applied to the IF amplifier (Q3), then applied to the 2nd mixer circuit (IC1, pin 16). AF signals from the FM IF IC (RF unit; IC1, pin 9) are applied to the MAIN unit via J300 pin 14. The AF signal applied to the [VOL] control (MAIN unit; R406) to control the audio level via the volume mute switch (Q316). The level controlled AF signals are applied to the AF power amplifier (IC305, pin 2) to drive an internal speaker (SP300) via the [SP] jack (J301).

4-1-6 SQUELCH CIRCUIT (RF AND MAIN UNITS)
(1) 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 (RF unit; IC2, pin 9) are applied to the active filter section (RF unit; 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 14 as the SQLIN signal. The SQLIN signal from IC2 (pin 14) passes through J300, pin 12, and is then applied to the CPU (MAIN unit; IC301, pin 46). The CPU analyzes the noise condition and outputs the RMUT and AFON signals to toggle the volume mute (MAIN unit; Q316) and AF mute (MAIN unit; Q311) switches. (2) 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; IC1, pin 9) passes through the AF control (MAIN unit; IC304) to control the volume mute and AF mute switches.
4-2-3 DRIVE/POWER AMPLIFIER CIRCUITS (RF UNIT)
The amplifier circuit amplifies the VCO oscillating signal to the output power level. The amplified transmit signal is passed through the antenna switching circuit (D1) and low-pass filter, and is then applied to the antenna. The modulated transmit signal is amplified at the pre-drive and drive amplifiers (Q5, Q6) after being amplified at the buffer amplifier (Q8). The amplified signal is power amplified at the power amplifier (Q4) to obtain 10 mW of RF power. The power amplified signal is then applied to the antenna via the low-pass filter circuits.
4-3 PLL CIRCUITS (RF UNIT)
A PLL circuit provides stable oscillation of the transmit frequency and receive 1st LO frequency. The PLL output compares the phase of the divided VCO frequency to the reference frequency. The PLL output frequency is controlled by the divided ratio (N-data) of a programmable divider. The PLL circuit consists of the VCO circuit (Q8, D8, D9). An oscillated signal from the VCO passes through the buffer amplifier (Q7) is applied to the PLL IC (IC2, pin16) and is prescaled in the PLL IC based on the divided ratio (N-data). The reference signal is generated at the reference oscillator (X2) and is also applied to the PLL IC. The PLL IC detects the out-of-step phase using the reference frequency and outputs it from pin 14. The output signal is passed through the loop filter (R44, C67) and is then applied to the VCO circuit as the lock voltage. If the oscillated signal drifts, its phase changes from that of the reference frequency, causing a lock voltage change to compensate for the drift in the oscillated frequency.
4-2 TRANSMITTER CIRCUITS
4-2-1 MICROPHONE AMPLIFIER CIRCUIT (MAIN UNIT)
AF signals from the internal/external microphone are applied to the microphone amplifier circuit and low-pass filter (IC304) via the microphone switch (Q313). The filiterd audio signals are applied to the modulation circuit on the RF unit via J300, pin 15 as the MOD signal.
2-2 MODULATION CIRCUIT (RF UNIT)
The filtered audio signals from J300, pin 15 (On the MAIN unit) are applied to the modulation circuit (D8, D9) to modulate transmit signals at the VCO circuit (Q8). The modulated signal is applied to the drive amplifier circuit.
