OPERATING FEATURES

2. Scan Operating 2-1. Scan Start Condition Two or more non-priority channels must be added to all channels that can be scanned. The transceiver must be in normal receive mode (PTT off). When you activate the key or the toggle switch (to right position) programmed to the scan function, the scan starts. The scan icon "SCN" lights and "SCAN" or revert channel (programmable) is indicated on 7-digit alphanumeric display.

2-2. Scan Stop Condition The scan stops temporarily if the following conditions are satisfied. 1) A carrier is detected, then signalling matches on channel for which receive the signalling is set by the programming software. 2) A carrier is detected on the channel for which receiving signalling is not set by the programming software or when the monitor (signalling cancel) function is activated.

2-3. Scan Channel Types 1) Priority channel is the most important channel for the scan, and always detects a signal during scan and when the scan stops temporarily. 2) Non-priority channels detects a signal during scan. For the channels that can be selected with the channel selector when the scan does not occur, adds an indicator "A" lights.

2-4. Priority Channel Setting Priority channel can be set as follows with the programming software (KPG-59D). 1) Specify priority channel as fixed priority channel. 2) Make selected channels, priority channels.

2-5. Scan Type According to the Priority Channel 1) When no priority channels are set : Only the non-priority channels are scanned. If a non-priority channel stops temporarily. 2) When one priority channel is set : Either priority channel is scanned. If a non-priority channel stops temporarily, a priority channel signal is detected at certain intervals. If a priority channel stops temporarily, it stops until there is no signal on the priority channel.

2-6. Revert Channel The revert channel is used to transmit during scanning and set by the programming software (KPG-59D). 1) Last called channel The transceiver reverts to the last called channel during the scan. 2) Last used channel The transceiver reverts to the last used (transmitted) channel during scan. "Last used" revert channel includes talkback function. 3) Selected with talkback The transceiver reverts to the channel before scanning or the channel that you changed during scan.

4

4) Selected channel The transceiver reverts to the channel before scanning or the channel that you changed during scan. 5) Priority with talkback The transceiver reverts to the priority channel. If you press PTT during a resume timer (dropout delay time, TX dwell time) or calling, you can transmit on current channel to answer to the call however revert channel is set to priority channel. After resume time, scan re-starts and transmission channel is return to priority channel. 6) Priority The transceiver reverts to the priority channel.

2-7. Scan End When you press the key once again, or the toggle switch (to left position) programmed to the scan function during scan mode, the scan ends. The scan icon "SCN" and "SCAN" or revert channel (programmable) display goes off.

2-8. Temporarily Delete/Add It is possible to delete or add channel temporarily during scan. When scan stops on unnecessary channel for example by interference of the other party, activate the delete/ add function (for example press the key), then that channel is deleted temporarily and scan re-start immediately. When you would like to add the deleted channel temporarily to scan sequence, select the desired (deleted) channel during scan, activate the delete/add function (for example press the key) before scan re-start. That channel is added temporarily to scan sequence. The temporary deleted or added channels are returns to pre-set delete/add, when the transceiver exits from scan mode.

OPERATING FEATURES 3. Optional Features You can use these features using the programming software (KPG-59D).

3-1. Beep Tones The beep tones (power on tone, control tone, warning tone, alert tone) are individually programmable to the fixed level 0 to 31 or follow the mechanical volume position.

3-2. Minimum Volume The minimum volume is programmable (0 to 31). The transceiver remains the minimum volume level however the mechanical volume position is set to zero.

3-3. BCL (Busy Channel Lockout) Override You can transmit in spite of Busy Channel Lockout situation. For example : To make an emergency voice call. To transmit under busy channel lockout situation, press PTT once more within approx. 500ms after the PTT release.

3-4. Selective Call Alert LED You can select whether or not the LED on the transceiver flashes in an orange color when Selective call was occurred.

3-5. Battery Warning This transceiver has battery warning feature. If the low voltage is detected during transmission, the transceiver warns it by flashing red "LED". Then more low voltage is detected during transmission, the transceiver stops transmission and warns it by flashing red "LED" and beep. Please notice "standard" for the battery exchange, charging time by flashing red LED and beep.

3-6. Busy LED You can program the enable or disable the busy "LED" function when a carrier is detected. "Disable" saves battery life.

3-7. TX LED You can program the enable or disable the transmission "LED" function.

3-8. 2-Digit 7-Segment Display You can use 2-digit 7-segment the display to display the channel number or group number. It is useful when the main (7-digit 13-segment) display indicates channel name.

3-9. Invert Display Main (7-digit 13-segment) display and sub (2-digit 7-segment) display can be programmed to invert display. It is easy to read the display when the operator suspended the transceiver on a waste belt. The operator also can change the display between normal and invert using key. Refer the invert display function of key function.

TK-190

3-10. Emergency Channel Display The transceiver can be programmed to display "EMERGENCY" channel name when it is in emergency mode. If you set to "off" by KPG-59D the transceiver shows selected group/channel/status before entering to the emergency mode however the transceiver is in an emergency mode.

3-11. Clear to Transpond The transceiver waits the transpond of 2-Tone/DTMF if channel is busy until channel open. This feature prevents the interference to other party.

3-12. External Speaker It can be selected if the receive sound is made by SP-Mic SP or the main body SP at a SP-Mic mount.

3-13. Mode (Enable/Disable) The transceiver has many special modes mainly for maintenance. · Panel Test mode · Clone mode · Main programming mode It is possible to set enable/disable for each mode. We recommend to set these mode to Disable after set up to save contents.

3-14. ID The transceiver is capable to have ID. The format is DTMF. The timing that the transceiver sends ID is programmable. Begin of TX : Connect ID is send on beginning of transmission. End of TX : Disconnect ID is send on end of transmission. Both : Connect ID is send on beginning of transmission and disconnect ID is send on end of transmission. Off : Sending ID function is disabled. There is also "PTT ID" setting for each channel. Refer "PTT ID" of channel feature.

3-15. OST (Operator Selectable Tone) The transceiver is capable to have "OST" function and 16 tone pair (QT/DQT) with max 7-digit name for each tone pair.

• "OST" Back Up The transceiver is programmable the selected "OST" code is memorized or not. If you set to Disable (no memorized), the "OST" function always starts at "off".

OPERATING FEATURES

3-17. "TOT" (Time-Out Timer) The transceiver has the "TOT". This parameter selects the period of time users can continuously transmit. When the selected period passes, the transceiver generates an warning tone and stops the transmission.

3-18. "TOT" Pre-Alert The transceiver has "TOT" pre-alert timer. This parameter selects the time at which the transceiver generates "TOT" pre-alert tone before "TOT" is expired. "TOT" will be expired when the selected time passes from a TOT pre-alert tone.

4. Channel Features You can use these features using the programming software (KPG-59D).

4-1. Alphanumeric Display (Channel Name) The programming software (KPG-59D) enables you to set the alphanumeric display for channel name. The total text size of channel name are 7-digits. For example, If you set 2-digits for group name, then you can use 5-digits for channel name. The characters can be used as shown in Figure 1.

3-19. "TOT" Re-Key Time The transceiver has "TOT" re-key timer. This timer is the time you can not transmit after "TOT" exceeded. After "TOT" re-key time expired you can transmit again.

A B C D E F G H

3-20. "TOT" Reset Time

J K L M N O P Q R

The transceiver has "TOT" reset timer. This timer is the minimum wait time allowed during a transmission that will reset the "TOT" count. "TOT" reset time causes the "TOT" to continue even after PTT is released unless the "TOT" reset timer has expired.

3-21. Signalling Signalling "AND/OR" sets the audio unmute condition for any channel programmed with the option signalling (2-Tone/ DTMF). AND : "AND" requires both the valid option signalling and the programmed QT/DQT to be received for audio to unmute (and initiate an option signalling decode alert). OR : "OR" requires either the valid option signalling or the programmed QT/DQT to be received for audio to unmute (an option signalling decode alert is only initiated if the proper option signalling is decoded).

CIRCUIT DESCRIPTION 3-3. IF amplifier

1. Overview The KENWOOD model TK-190 is a VHF/FM hand-held transceiver designed to operate in the frequency range of 29.7 to 37MHz(K),35.0 to 50.0MHz(K2), the unit consists of a receiver, a transmitter, a phase-locked loop(PLL) frequency synthesizer, power supply circuit, a control unit.

The 1st IF signal is amplified (Q302) and fed into IC300 in the FM IC. The IF signal is then mixed with the 2nd local oscillator frequency of 129.005MHz to generate the 2nd IF of 455kHz. The 455kHz signal is then passed through a ceramic filter (CF300) and fed back into IC300 for additional amplification.

2. Circuit Configuration by Frequency The receiver is a double-conversion super-heterodyne with a first intermediate frequency (IF) of 128.55MHz and a second IF of 455kHz. Incoming a signals from the antenna are mixed with the local signal from the PLL1 to produce the first IF of 128.55MHz. This is then mixed with the 129.005MHz seconds local oscillator output to produce the 455kHz second IF. This is detected to give the demodulated signal. The transmit signal is modulated PLL2VCO2(129.005MHz) from the microphone. The transmit signal frequency is down-conversion with PLL2 and PLL1. It is then amplified and sent to the antenna.

The signals are then fed into band-pass filter that uses varactor diode tuning to reject unwanted signal components, and is fed to the 1st mixer.

3-2. First mixer The 1st mixer uses the GaAs IC (IC200). The 1st mixer mixes the signal with the 1st local oscillator frequency from the VCO1, and converts to the 1st IF (128.55MHz). The signal then passes through monolithic crystal filter (XF300) to remove unnecessary nearby frequency components. The signal from the MCF is used as the 1st IF signal.

3-5. Squelch circuit

The demodulated signal from IC300 goes through IC301, and is amplified by IC601 (2/2), high-pass filtered, low-pass filtered, high-pass filtered, band-eliminate filtered, and deemphasized by IC607. The signal then goes through an electronic volume control (IC603), an AF amplifier IC604 (2/2), and an AF switch (Q8 is on and Q7 is on of the control unit), and is routed to audio power amplifier (IC1 of the control unit), where it is amplified and output to the internal speaker.

It amplifies the demodulated noise signal from FM IC (IC300) after filtering through BPF circuit. Then, the amplified signal is coverted to DC signal by the detection circuit. The coverted signal is feeded through the microprocessor (IC 406) and the voltage level is detected by ADC (A/D converter) to control the squelch circuit. AF OUT 9

The audio mute signal (AMP SW) from the microprocessor becomes Low in the standby and Q5, Q6 which are power supply circuit for IC1 turn off. When the audio is output, AMP SW becomes High to turn Q5, Q6 on, and voltage is supplied to power terminal VP of IC1. Speaker switching is done from IC403 (TX-RX unit) by INT AFC or EXT AFC. First, the logic level at the speakers switching terminal (SSW) on the universal connector is input to the microprocessor (IC406 TX-RX unit). The microprocessor then outputs data to IC403 based on this input. When there is no SP-MIC installed, this logic level is high. When the INT AFC is high, the EXT AFC goes low, so the AF signal is only input to the amplifier for the internal speaker (INT SP) of IC1. However, when a SP-MIC has been installed, this logic level is low, so the INT AFC goes low and the EXT AFC goes high. So that the AF signal is input only to amplifier for the external speaker (EXT SP) of IC1.

CIRCUIT DESCRIPTION 4-3. Down-mixer

4. Transmitter System

At Q102, a modulated VCO2 signal is mixed with 2nd local oscillator signal, 129.005MHz. The difference of the two signals is used for the transmission signal (29.7 – 37MHz). The output was filtered through a LPF (Low Pass Filter).

4-1. Microphone amplifier The signal from IC3 (control unit) goes through the mute switch (Q403). When the SP-MIC is not attached, the microphone switching terminal (MSW) on the universal connector becomes High, and mute switch (Q403) is turn on. When the SP-MIC is attached, MSW is connected to GND at inside of SP-MIC. For this reason, Q403 is turned off, the internal microphone is muted, and only the input of the external microphone is supplied to the microphone amplifier of the TXRX unit. The signal from microphone passes through the limiter circuit in D601, through the high-pass filter, the ALC circuit, the low-pass filter, the high-pass filter, and pre-emphasis/ IDC circuit in IC607. When encoding DTMF, mute switch (Q601) is turned off for muting the microphone input signal. The signal passes through the D/A converter (IC603) for the maximum deviation adjustment. And enters the summing amplifier consisting of IC605 (1/2), and is mixed with the low speed data from the CPU (IC406). The output signal from the summing amplifier goes to the VCO2 modulation input.

4-4. Drive and Final amplifier The signal from Down-mixer is amplified by the pre drive (Q32) and drive amplifier (Q1) to 500mW. The output of the drive amplifier is amplified by the RF power amplifier (Q1,Q2 in the FINAL unit) to 6W (1W when the power is low). The RF power amplifier consists of two MOS FET transistor. The output the RF power amplifier is then passed through the transmit-receive (TX-RX) antenna switching (D2 is on) and the harmonic filter (LPF) and applied to the antenna terminal.

The two signals from INT MIC (Main & Sub) are input to the positive (+) input (Sub) and to the negative (–) input (Main) of the IC3. If the same signal is input to both Main and Sub, the Main signal is canceled at the output of IC3 (pin 7). In other words, noise words, noise from nearby sources not directly connected the transceiver enters the Main and Sub inputs at the same signal and is therefore canceled out. When a signal is only input to Main and there is no signal at Sub, the Main signal is output as is, from IC3 (pin 7). In other words, only the voice audio of the operator in extremely close proximity to the Main MIC is input to Main so that the signal is output as is from IC3 (pin 7). Also, when the "N/C" switch is set to "L", transistor Q14 turns off so Sub microphone turns off and operation is the same as above.

TK-190 CIRCUIT DESCRIPTION 4-5. APC circuit The APC circuit always monitors the current flowing through the RF power amplifier (Q1, Q2) and keeps a constant current. The voltage drop at R14, R15, and R16 is caused by the current flowing through the RF power amplifier and this voltage is applied to the differential amplifier (IC2 1/2). IC2 (2/2) compares the output voltage of IC2 (1/2) with the reference voltage from IC1, and the output of IC2 (2/2) controls the VGC of the RF power amplifier to make the both voltages to same voltage. The change of power high/low is carried out by the change of the reference voltage. Q4, Q5, and Q8 are turned on in transmit and the APC circuit is active. (See Figure 6)

5. PLL Frequency Synthesizer

6. Power Supply Circuit

The frequency synthesizer consists of the VCXO (X1), VCO (L800), PLL IC (IC101) and buffer amplifiers. The VCXO generates a 16.8MHz reference frequency. The frequency stability is within ± 5.0ppm (temperature range of –30 to +60°C). The output of the VCXO is applied to pin 8 of the PLL IC. The VCO of TK-190 covers a 7.3MHz frequency spread. VCO (L800) has 2 internal VCOs. One for the 1st local oscillator (158.25 – 166.005MHz) and another one for the 2nd local oscillator (129.05MHz). Each output is connected to a dual PLL IC (IC101). VCO1 oscillates at 158.705 – 166.005MHz during transmission and it oscillates at 158.205 – 166.55MHz during reception. VCO2 oscillates at 129.005MHz during both reception and transmisson. However, the oscillated signal is modulated during transmission. Each PLL circuit has LPFs and buffer amplifiers. The output of VCO1 goes through the buffer amplifier, then the output is switched either for the 1st local oscillator circuit of the receiver or transmitter. The output of VCO2 goes through the buffer amplifier. The output is connected to both the receiver and transmitter 2nd local oscillator circuits.

Battery +B is supplied via a 3A fuse from the battery terminal connected to the TX-RX unit. After passing through the power switch power supply (SB) is applied to the two AVR ICs, and AVR circuit. IC401 supplies 5V (5CM) to the control circuit. IC402 supplies 5V (5C) to the common circuit. AVR circuit (Q400,Q402) supplies voltage to the TX circuit. 5R and 5RB is 5V for reception and output during reception. 5T and 5TB is 5V for transmission and output during transmission.

DISASSEMBLY FOR REPAIR

TK-190

Disassembly of Front Case and Chassis

Remove the Side Key Assy

1. Remove the 2 screws ( 1 ) and a cap fixed screw ( 2 ). 2. Press the chassis bottom upwards and remove the clips ( 3 ) at the top. The front case is still connected to the chassis by the FPC at this time so be gentle when lifting upwards, otherwise unwanted stress is applied on the FPC. 3. The front case and chassis can only be opened to the side when connected by the FPC ( 4 ).

1. The side key assy is clips form a slide-hook structure. Lift up gently and take from the side ( 12 ).

Side key assy

Front case Chassis

The waterproof packing for the front case cannot be removed unless the control unit is detached.

Chassis

Remove the TX-RX Unit from the Chassis 1. The TX-RX unit cannot be removed simply by removing the seven screws ( 5 ). 2. A total of 9 solder connections, 6 on the RF power module ( 6 ) and 3 on the antenna daughter board ( 7 ) must be disconnected.

Disassembly of the Panel Assy 1. The LCD assy and toggle switch are joined by wire ( 13 ). Use caution not to break this wire during handling.

Remove the Universal Connector 1. The universal connector ( 8 ) is fastened to the chassis with double-side tape. 2. Press firmly with a tool such as a screwdriver and so that it can peel ( 10 ). Note : You must replace both parts together when replacing the universal connector or the FPC ( 11 ).

■ The following parts are required for adjustment 1. Antenna connector adapter

Caution

The antenna connector of this radio uses an SMA terminal. Use an antenna connector adapter [SMA(f) – BNC(f) or SMA(f) – N(f)] for adjustment. (The adapter is not provided as an option, so buy a commercially-available one.)

1. When connecting the plug to the universal connector of the radio, a short circuit may occur. To provent this, be sure to turn the radio POWER switch off. 2. Since the RX AF output is a BTL output, there is a DC component. Isolate this with a capacitor or transformer as shown in the figure. 3. Do not connct an instrument between red or black and GND.

Note When the antenna connector adapter touches the knob, draw out the knob to mount the connector.

• Universal connector 2. Universal connector Use the interface cable (KPG-36) for PC tuning or the lead wire with plug (E30-3287-08) and screw (N08-0535-08) for panel tuning. Connct the plug to the universal connector of the radio and tighten the screw. The lead wire with plug (E30-3287-08) and screw (N080535-08) terminals are as follows. Numbers are universal connector terminal numbers.
