The 0 MHz nd local signal (LO) from the PLL unit enters the MAIN unit via J to be applied to the nd mixer. Received signals from the antenna connector pass through the transmit/receive switching relay (FILTER board RL) and are then applied to the MAIN unit via J. The signals pass through the protection relay (RL),. MHz cut off high-pass filter (L L,, ) and are then applied to one of nine bandpass filters (including one low-pass filter for below.0 MHz). These filters are selected by the filter control signals (B0 B) as described in the table below. The nd IF signal is passed through the noise blanker gate (D, D) and amplified at the nd IF amplifier (Q) and then applied to one of the MHz IF filters as described below. The passed signal is amplified at the two stage nd IF amplifiers (Q, Q) and is applied to a demodulator circuit (D for HE or I0 for JE and others). The filtered signals pass through the 0 MHz cut-off lowpass filter (L, L, 0, ), and are then applied to the st mixer circuit (Q, Q).

B L *Built-in to the GMDSS versions -- NOISE BLANKER IRUIT (MAIN UNIT) The noise blanker circuit cuts off the IF circuit line at the moment of receiving a pulse-type noise. A portion of the nd IF signal between resonator circuits (L, L after stage of the nd mixer, D) is amplified at the noise amplifiers (Q, I, Q). The signal is then detected at the noise detector (D) to convert the noise components to D voltages. -- ST MIXER AND IF IRUITS (MAIN UNIT) The st mixer circuit converts the received signals into a fixed frequency,.0 MHz st IF signal using the PLL output frequency. By changing the PLL frequency, only the desired frequency is picked up at the pair of crystal filters (FIa, FIb) at the next stage. The signals are then applied to the noise blanker switch (Q, Q). At the moment the detected voltage exceeds the Q s threshold level, Q outputs a blanking signal to close the noise blanker gate (D, D) by applying reverse-biased voltage. Q turns the noise blanker circuit ON and OFF. The IF amplifier (Q) and resonator circuits are designed between the filter pair. The PLL output signal (LO) enters the MAIN unit via J and is amplified at the st LO amplifier (Q) and then applied to the st mixer (Q, Q) REEIVE FREQUENY ONSTRUTION HE st mixer Q, Q LPF or BPF 0..

The detected voltage is also applied to the noise blanker AG circuit (Q, Q0) and is then fed back to the noise amplifier (I) as a bias voltage. The noise AG circuit prevents closure of the noise blanker gate for long periods by non-pulse-type noise. The time constant of the noise blanker AG circuit is determined by R and. -- S-METER IRUIT (MAIN UNIT) The S-meter indicates the AG level on the display, since the AG level varies with the received signal strength. The AG bias voltage (AG time constant line) from the AG amplifier (Q) is inverted and amplified at the meter amplifier (Ib). The amplified signal is applied to the PU via the RSM line. -- DEMODULATOR IRUIT (MAN UNIT) This circuit mixes the nd IF and BFO signals to pick up the AF components (except HE mode). The nd IF signal from the nd IF amplifier (Q) is applied to the balanced mixer (I0, pin ). The.0.00 MHz BFO signal from the PLL unit is also applied to I0 (pin 0). AF signals are output from pin and are then applied to the AF circuits. -- AF AMPLIFIER IRUITS (MAIN UNIT AND LOGI BOARD) AF signals from the demodulator or HE detector circuits pass through the active low-pass filter (I0b) and squelch gate (Ia), and are then applied to the electronic volume control (I). The PU (I, pin ) outputs the volume control signal ( to V) according to the [VOLUME] control setting. -- HE DETETOR IRUIT (MAIN UNIT) The nd IF signal from the nd IF amplifier (Q) is applied to the AM detector circuit (D) to be demodulated into AF signals. The detected signals are amplified at the buffer amplifier (Q), and are then applied to the AF circuits. The AF output signal from I ( pin) are supplied to the LOGI unit via J. The signals are amplified at the AF power amplifier (I00) and are then applied to the internal speaker via microphone connector (pins, ) and external [SP] jack via the MAIN unit. -- AG IRUIT (MAIN UNIT) The speaker switch relay (RL00) is connected to the ( ) terminal of internal speaker for the [SPEAKER] switch function. The AG (Automatic Gain ontrol) circuit reduces IF amplifier gain to prevent the receiver circuit from distorting and to keep the audio output at a constant level. A portion of the IF signals from the nd IF amplifier (Q) is detected at the AG detector circuit (D) and is then applied to the AG amplifier (Q) to control the AG time constant line. The reference voltage of the AG line is controlled by the RFG line which comes from the PU for the RF gain setting. --0 SQUELH IRUIT (MAIN UNIT) The transceiver has two squelch circuits, voice activated squelch for JE/HE and S-meter squelch for AA/FB/ JB. () AF ATIVATED SQUELH A portion of the AF signal from the active low-pass filter (I0b) is amplified at the limiter amplifier (I0a) and is then applied to the one-shot multi-vibrator (Ic, Id). The one shot multi-vibrator functions as an F-V converter which generates a signal only when audio signals are received. When receiving a strong signal, the detected voltage increases and the voltage of the AG line is decreased by the AG amplifier (Q) via the V voltage line. The AG line is used for the bias voltage of the IF amplifiers (Q, Q, Q, Q), so that these amplifiers reduce gain. When the strong signal disappears, the AG line voltage is released by /R and 0/R. The output signals pass through the NOR gate (Ib) and then the Hz low-pass filter (Ia) to remove the remaining noise components. The filtered signal is applied to the window comparator (Ib). The NOR gate (Ib) deactivates the audio activated squelch during AA/FB/JB mode operation. The AG switch (Q, D) turns the AG circuit OFF when the AG OFF function activates. The AG-fast switch (Q) sets the AG line as fast-release during scanning, AA mode selection and DS operation. nd IF filters AG IRUIT HE derector st IF signal Q D Q AG-fast control V AG time constant line Q Q W, DS, SAN Demodulator Q 0 R AG amplifier RFG (RF gain control) 0 to V D AG detector V Q - AG OFF control Q
The comparator outputs High when the integrated signals exceed the reference voltage., R0 and R0 are used as a time constant circuit. The resulting signal output from Ia is inverted at Q and is then applied to the PU as the SQLS signal. The PU controls the squelch gate (Ia) when the SQLS signal is received. The SSB signal from FI is amplified at the MHz amplifiers (Q Q) and is then applied to the mixer circuit (D). The switching diode (D) is turned ON when R voltage disappears. () HE AND RE MODES An SSB signal is applied to the IF amplifier (Q) in the same manner as with JE/JB mode. The BFO signal from the PLL unit is amplified at the buffer amplifier (Q0) and is then applied to the IF amplifier (Q) as a carrier signal to be added to an SSB signal. R and R adjust the carrier levels in HE and RE modes, respectively. () S-METER SQUELH The S-meter signal from Ib is applied to the squelch comparator (Ia) to close or open the squelch circuit. The reference voltage is adjusted by R and then applied to the ( ) terminal of the comparator (Ia). When the S-meter signal exceeds the reference voltage, the comparator outputs High to the PU via Ia and Q in the same manner as the voice activated squelch circuit. () AA AND FB MODES The W or FSK voltage are applied to the balanced modulator (I, pin ) to upset the balance and create a carrier signal.

External modulation inputs from the A, NBDP, DS sockets or a -tone emergency signal from the PU are applied to the balanced modulator directly via AF switches (I I). The.0 MHz IF signal passes through the filter (FIb) and is then applied to the nd mixer circuit. -- MODULATION IRUIT (MAIN UNIT) () JE AND JB MODES The balanced modulator is used for JE and JB modes to add the audio signal to the BFO frequency, and outputs the IF signal while suppressing the BFO signal. -- ND MIXER IRUIT (MAIN UNIT) The filtered signal is mixed with a PLL output frequency (LO:..0 MHz) at the nd mixer circuit (Q, Q) to produce an RF signal which is the same frequency as the displayed one. The AF signals from the microphone amplifier or external audio from the modulation terminals are applied to the balanced modulator (I, pin ). The BFO signal from the PLL unit is applied to (I, pin 0) as a carrier signal. A double sideband signal is output from I (pin ), and is then applied to the MHz filter (FI) to create an SSB signal. -- RF FILTER IRUIT (MAIN UNIT) The RF signal passes through the low-pass filter (L, L,, 0, ) and is then amplified at the RF amplifier (Q). R adjusts the balanced level of I for maximum carrier suppression. In JB mode, the BFO frequency is shifted. khz to set the transmit frequency the same as the displayed frequency. The amplified signal is applied to one of nine RF filters. These RF filters are commonly used with the receiver circuit which consists of eight high-pass filters and one lowpass filter.

() IF AL IRUIT (MAIN UNIT) A portion of the IF signals from the IF amplifier (Q) is applied to the IF AL circuit. The signal is amplified at Q and then detected at the AL detector (D). The detected signal is amplified at the AL amplifier (Ib) and is then applied to the comparator (Ia). The driver and power amplifiers form class AB push-pull circuits. Bias voltage to these transistors is produced by diodes (D00 D00) which have temperature junctions with the transistors. The reference voltage for the comparator is set by R. The antenna tuning control voltage (TUN) and low power set signal (PO) are also affected by the reference voltage to decrease the IF signal level. The amplified signal is then applied to one of eight lowpass filters to suppress high harmonic components. The filtered signal passes through the power detector circuit (FILTER board; L) and transmit/receive switching relay (FILTER board; RL) and is then applied to the antenna connector. The comparator output controls the gate bias of the IF amplifier (Q), so that the IF signal level is determined by the reference voltage of the comparator (Ia).
