Kenwood tk3160 user manual

Note: To lift the locking bracket after it has been installed, use a piece of hardened plastic or metal, such as a small screwdriver.

Lift the bracket by its tab, beside the screwhole, taking care not to damage the bracket. Lights red while transmitting. Lights green while receiving. If programmed by your dealer, flashes red when the battery power is low while transmitting. Turn clockwise to switch ON the transceiver. Rotate to adjust the volume. To switch OFF the transceiver, turn counterclockwise fully. This is a PF Programmable Function key.

Press it to activate its auxiliary function page 4. The default setting for this key is None. The default setting for this key is Squelch Off Momentary. Press each key to activate its auxiliary function. Connect the TK to the personal computer with the interface cable.

When the PC sends a command, the radio enters PC mode. The data can be input to or read from TK and edited on the screen. The programmed or edited data can be printed out. It is also possible to tune the transceiver. Separating the case assembly from the chassis. Remove the volume knob z. Remove the two screws x. Lift the chassis c , and remove it from the case assembly. Note: After separating the case assembly from the chassis,. Channel knob. Remove the solder from the antenna terminal using a soldering iron m , then lift the unit off.

Install the speakers so that they do not protrude from the cushion. Perform the wire styling of speakers as shown in a photograph. The receiver utilizes double conversion. The first IF is The first local oscillator signal is supplied from the PLL circuit. The PLL circuit in the transmitter generates the necessary frequencies.

X3 multiply TCXO The input voltage to the variable capacitor is regulated by voltage output from the microprocessor IC The signal from the front end is mixed with the first local oscillator signal generated in the PLL circuit by Q to produce a first IF frequency of The resulting signal passes through the XF MCF to cut the adjacent spurious and provide the opitimun characteristics, such as adjacent frequency selectivity.

The first IF signal is passed through a four-pole monolithic crystal filter XF to remove the adjacent channel signal. The second mixer mixes the first IF signal with the The second IF signal is passed through the ceramic filter CF to remove the adjacent channel signal.

The filtered second IF signal is amplified by the limiting amplifier and demodulated by the quadrature detector with the ceramic discriminator CD The demodulated signal is routed to the audio circuit. Narrow and Wide settings can be made for each channel by switching the demodulation level. The signal then goes through an AF volume control VR , and is routed to an audio power amplifier IC where it is amplified and output to the speaker.

IC determines whether to output sounds from the speaker by checking whether the input voltage is higher or lower than the preset value. See Fig. If it matches, IC carries out a specified operation, such as turning the speaker on.

And is routed to the VCO. When encoding MSK, the microphone input signal is muted. The decoded information is then processed by the CPU. The PLL circuit generates the first local oscillator signal for reception and the RF signal for transmission. The frequency step of the PLL circuit is K The divided signal is compared in phase with the 5 or 6. The output signal from the phase comparator is filtered through a low-pass filter and passed to the VCO to control the oscillator frequency.

The operating frequency is generated by Q6 in transmit mode and Q5 in receive mode. The oscillator frequency is controlled by applying the VCO control voltage, obtained from the phase comparator, to the varactor diodes D3,D5,D7 and D8 in transmit mode and D4,D6,D9 and D10 in receive mode.

The TX pin is set high in transmit mode. The output of the drive amplifier is amplified by the RF power amplifier Q to 5. The output of the RF power amplifier is then passed through the harmonic filter LPF and antenna switch D and D and applied to the antenna terminal. If a pulse signal appears at the LD pin of IC1, an unlock condition occurs, and the DC voltage obtained from C19,R6 and Q1 causes the voltage applied to the microprocessor to go high.

When the microprocessor detects this condition, the transmitter is disabled, ignoring the push-to-talk switch input signal. The signal from the microphone passes through the IC The signal passes through a low pass CR filter, mixes with the audio signal, and goes to the VCO modulation input. TX deviation is adjusted by the CPU. High-speed data is output from pin 2 of the CPU. The signal is mixed with the audio signal and goes to the VCO.

The demodulated data goes to the CPU for processing. There are 3. The control circuit consists of a microprocessor IC and its peripheral circuits. It controls the TX-RX unit. IC mainly performs the following:. The microprocessor IC operates at a clock of 7. The battery voltage is checked using by the microprocessor. The transceiver generates a warning tone when it falls below the warning voltage shown in the table.

However, the LED does not blink during reception. During transmission, the LED blinks to generate the warning tone of a low battery voltage. A message tone beeps while the PTT switch is released.
