4. Clone Mode

4-1. Outline

"Clone Mode" copies the transceiver data to another transceiver.

The dealer can copy the transceiver data to another transceiver even without the use of a personal computer.

4. 复制模式

4-1 概要

“复制模式”可以将一台手持机的数据复制到其它的手持机。

经销商甚至不使用个人电脑也可以将一台手持机的数据复制

到其它的手持机。

4-2. Example

The transceiver can copy the programming data to one or more transceivers via RF communication.

The clone master and clone slave/s must be in Clone mode.

4-3. Operation

1. To switch the clone slave/s to Clone mode, press and hold the [PTT] and [side2] keys while turning the transceiver power ON.

2. Wait for 2 seconds. The LED will light orange and the transceiver will announce "Clone".

3. Select a channel table number using Side1(increment channel table) and Side2(decrement channnel table) keys.

4. To switch the clone master to Clone mode, press and hold the [PTT] and [side2] keys while turning the transceiver power ON.

5. Wait for 2 seconds. The LED will light orange and the transceiver will announce "Clone".

6. Select the same channel table number as the clone slave/s.

7. Press [PTT] on the clone master to begin data transmission.

When the clone slave starts to receive data, the LED will light green.

When the clone master finishes sending data, a

"confirmation" tone will sound.

If data transmission fails while cloning, an "error" tone will sound from the Slave unit.

4-2 例:

手持机可以通过 RF 通信复制编程数据到一台或更多的手持

机。

复制主机和复制子机必须处于复制模式。

4-3 操作方法

1. 将子机切换到复制模式，旋转手持机电源的同时，持续按

[PTT] 键和 [侧 2] 键。

2. 等待2秒。LED将呈橘黄色并且手持机将发出"复制"的声音。

3. 用侧 1 (频道表递增) 键和侧 2 (频道表递减) 键选择频道表号

码。

4. 将主机切换到复制模式，旋转手持机电源的同时，持续按

[PTT] 键和 [侧 2] 键。

5. 等待2秒。LED将呈橘黄色并且手持机将发出"复制"的声音。

6. 选择与复制子机相同的频道表号码。

7. 按复制主机上的 [PTT]，开始数据传输。

当复制子机开始接收数据时，LED 将呈绿色。

当复制主机完成传送数据时，将发出一个“确认”音。

如果在复制过程中数据传输失败，子机将发出一个"错误"音。

8. 如果复制失败，子机回到用户模式时数据随即消失。

9. 当复制成功时，子机的 " 扫描 " 和 " 键锁定 " 功能将回到它们

的初始值 (扫描 =OFF, 键锁定 =OFF)

TK-2207

REALIGNMENT /

模式组合

8. If the cloning fails, no data will be available in the Slave unit when it is returned to User mode.

9. When the cloning is successful, the Slave unit's "Scan" and

"Key lock" functions will return to their default values (Scan

= OFF, Key lock = OFF).

Notes:

• The dealer can clone data to two or more transceivers by repeating the above procedures.

• If the transceivers Clone Mode is configured as "Disabled", the transceiver cannot enter Clone mode.

• The table shown below will cover the frequency tables used for wireless cloning.

• Clone mode cannot be entered in battery low state.

• A unit cannot be a "Master Unit" if it is unprogrammed. If

[PTT] is pressed, an "error" tone will sound.

• The language used in cloning depends on the "Model type" setting, not the FPU setting. C, C2, C5 and C6 type

TK-3207 transceivers will use Chinese. Other types English.

• Once a unit is set to be the Master, it cannot be a slave after the data has been transmitted. This protects the data in the Master unit.

• Electronic interface may cause a failure in data transfer during Wireless Clone, such as when waveforms or electromagnetics are being performed at the workbench.

• Clone mode can be used ONLY by the authorized service personnel.

• The Clone mode setting must be configured as "Disable" before being delivered to the end-user.

• To clone, replace the antenna from both the master transceiver and the slave transceiver with a dummy load.

• The transmit output power is automatically set to Low in Clone mode.

注释：

•

经销商可以反复上述过程复制数据到 2 个或更多的手持机。

•

如果手持机复制模式被设置为“无效”，则手持机不能进入复

制模式。

•

下表包含了无线复制用的频率表。

•

当电池处于低电压状态时不能进入复制模式。

•

如果手持机是非编程的它将不能成为主机。如果按[PTT]，将

发出一个 " 错误 " 音。

•

复制时所用的语言是根据 " 样机类别 " 设置，而不是 FPU 设

置，TK-3207 的 C，C2，C5 和 C6 类别的手持机用中文，其它

类别用英文。

•

手持机一旦被设置为主机，数据传送以后，它就不能成为子

机。这是为了保护主机里的数据。

•

在无线复制的数据传输过程中，例如在工作台产生的电波或

电磁干扰有可能引起传输失败。

•

复制模式可以仅被批准的服务人员使用。

•

在交付给最终用户之前，复制模式设置必须被设置为“无

效”。

•

为了复制，将模拟负载代替主手持机和子手持机的天线。

•

在复制模式，发射功率自动设定为低。

The signal coming from the antenna passes through the transmit/receive switching diode circuit, (D103,D104,D105 and D106) passes through a BPF (L214 and L213), and is amplified by the RF amplifier (Q205).

The resulting signal passes through a BPF (L209 and L211) and goes to the mixer. These BPFs are adjusted by variable capacitors (D203,D204,D205 and D206). The input voltage to the variable capacitor is regulated by voltage output from the microprocessor (IC405).

3) IF Amplifier Circuit

The first IF signal is passed through a four-pole monolithic crystal filter (XF201) to remove the adjacent channel signal.

The filtered first IF signal is amplified by the first IF amplifier

(Q203) and then applied to the lF system IC (IC201). The

IF system IC provides a second mixer, second local oscillator, limiting amplifier, quadrature detector and RSSI

(Received Signal Strength Indicator). The second mixer mixes the first IF signal with the 38.4MHz of the second local oscillator output (TCXO X1) and produces the second

IF signal of 450kHz.

The second IF signal is passed through the ceramic filter

(CF201) 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 (CD201). The demodulated signal is routed to the audio circuit.

4) Wide/Narrow Switching Circuit

Narrow and Wide settings can be made for each channel by switching the demodulation level.

The WIDE (low level) and NARROW (high level) data is output from IC405, pin 45.

When a WIDE (low level) data is received, Q202 turn on.

When a NARROW (high level) data is received, Q202 turn off.

Q202 turns on/off with the Wide/Narrow data and the

IC201 detector output level is switched to maintain a constant output level during wide or narrow signals.

3) 中频放大电路

第一中频信号通过晶体滤波器 (XF201) 消除相邻信道的信号。

经滤波的第一中频信号被第一中频放大器（Q203）放大并进

入中频系统芯片（IC201）。中频系统芯片提供第二混频器，第

二本振信号，限幅放大器，正交检测器和 RSSI（接收信号强

度指示器）。第二混频器将第一中频信号与 38.4MHz 的第二本

振信号输出（TCXO X1）进行混频，并生成 450kHz 的第二中

频信号。

第二中频信号通过陶瓷滤波器（CF201）继续消除相邻信道的

信号。经滤波的第二中频信号被限幅放大器放大并被带有陶

瓷鉴频器（CD201）的正交检测器解调。经解调的信号进入音

频电路。

4) 宽 / 窄开关电路

可以通过开启宽窄开关对各信道进行宽窄设定。

6) Squelch

Part of the AF signal from the IC enters the FM IC (IC201) again, and the noise component is amplified and rectified by a filter and an amplifier to produce a DC voltage corresponding to the noise level.

The DC signal from the FM IC goes to the analog port of the microprocessor (IC405). IC405 determines whether to output sounds from the speaker by checking whether the input voltage is higher or lower than the preset value.

To output sounds from the speaker, IC405 sends a high signal to the SP MUTE line and turns IC302 on through

Q303,Q304,Q305,Q306 and Q316. (See Fig. 4)

7) Receive Signalling

(1) QT/DQT

The output signal from FM IC(IC201) enters the microprocessor(IC405) through IC301. IC405 determines whether the QT or DQT matches the preset value, and controls the SP MUTE and the speaker output sounds according to the squelch results.

(2) MSK (Fleet Sync)

The MSK input signal from the FM IC goes to pin 31 of IC 301.

The signal is demodulated by MSK demodulator in IC 301.

The demodulated data goes to the CPU for processing.

3. PLL Frequency Synthesizer

The PLL circuit generates the first local oscillator signal for reception and the RF signal for transmission.

14

1) PLL

The frequency step of the PLL circuit is 2.5, 5, 6.25 or

7.5kHz.

A 12.8MHz reference oscillator signal is divided at IC1 by a fixed counter to produce an oscillator (VCO) output signal which is buffer amplified by Q2 then divided in IC1 by a programmable counter. The divided signal is compared in phase with the 5 or 6.25kHz reference signal from the phase comparator in IC1. The output signal from the phase comparator is filtered through a low-pass filter and passed to the VCO to control the oscillator frequency. (See Fig. 5)

3. PLL 频率合成

信号。

1) PLL

PLL 电路的频率步进是 2.5, 5, 6.25 或 7.5kHz。

12.8MHz 的参考振荡信号在 IC1 中被一个固定计数器分频。

振荡器 (VCO) 的输出信号由 Q2 缓冲放大,然后在 IC1中被一

个可编程双模块计数器分频。分频的信号在 IC1 的相位比较

器中进行比较。生成的信号通过一个低通滤波器滤波后传送

到 VCO 控制振荡器频率。（见图 5）

TK-2207


电路说明

2) VCO

The operating frequency is generated by Q4 in transmit mode and Q3 in receive mode. The oscillator frequency is controlled by applying the VCO control voltage, obtained from the phase comparator, to the varactor diodes (D4 and

D7 in transmit mode and D5 and D9 in receive mode). The

RX pin is set high in receive mode causing Q5 turn on.

The TX pin is set high in transmit mode. The outputs from

Q3 and Q4 are amplified by Q6 and sent to the RF amplifiers.

2) VCO

所使用的频率在发射模式时由 Q4 生成，在接收模式时由

Q3 生成。

通过将从相位比较器所获得的 VCO 控制电压输送给可变二

极管 (在发射模式时为D4和D7，在接收模式时为D5和D9) 来

控制振荡频率。在接收时 RX 脚被设定为高，使 Q5 接通。

发射时 TX 脚被设定为高。Q3 和 Q4 的输出被 Q6 放大并且传

送给 RF 放大器。

3) 失锁检测器

如果脉冲信号出现在IC1的LD管脚上，则发生了失锁的情况，

从 C4，R5 和 D1 获得的 DC 电压使微处理器的输入电压变低。

微处理器检测到这个情况后发射被禁止，忽略 PTT 开关的输

入信号。

3) Unlock Detector

If a pulse signal appears at the LD pin of IC1, an unlock condition occurs, and the DC voltage obtained from C4,R5 and D1 causes the voltage applied to the microprocessor to go low. When the microprocessor detects this condition, the transmitter is disabled, ignoring the push-to-talk switch input signal.

4. Transmitter System

1) Microphone Amplifier

The signal from the microphone passes through the IC301.

When encoding DTMF, it is turned OFF for muting the microphone input signal by IC301.

The output of the drive amplifier is amplified by the RF power amplifier (Q106) to 5.0W (1W when the power is low). The

RF power amplifier consists of two MOS FET stages. The output of the RF power amplifier is then passed through the harmonic filter (LPF) and antenna switch (D103 and

D104) and applied to the antenna terminal.

2) 驱动器和终端放大器

3) APC Circuit

The APC circuit always monitors the current flowing through the RF power amplifier (Q106) and keeps a constant current.

The voltage drop at R127, R128 and R129 is caused by the current flowing through the RF power amplifier and this voltage is applied to the differential amplifier IC101(1/2).

IC101(2/2) compares the output voltage of IC101(1/2) with the reference voltage from IC405. The output of IC101(2/2) controls the VG of the RF power amplifier, drive amplifier and pre-drive amplifier to make both voltages the same.

The change of power high/low is carried out by the change of the reference voltage.

3) 自动功率控制 (APC) 电路

APC 电路一直监视通过射频功率放大器 (Q106) 的电流并保

5. Power Supply

There are four 5V power supplies for the microprocessor:

5M, 5C, 5R, and 5T. 5M for microprocessor is always output while the power is on. 5M is always output, but turns off when the power is turned off to prevent malfunction of the microprocessor.

5C is a common 5V and is output when SAVE is not set to

OFF.

5R is 5V for reception and output during reception.

5T is 5V for transmission and output during transmission.

6. Control Circuit

(6) Transmitting tone and encode data.

1) Frequency Shift Circuit

The microprocessor (IC405) operates at a clock of

7.3728MHz. This oscillator has a circuit that shifts the frequency by BEAT SHIFT SW (Q407,Q408).

A beat sound may be able to be evaded from generation if

“Beat Shift” is set to ON when it is generated in the internal spurious transmission modulated sound of a transceiver.

(2) DTMF

5 . 电源

本机用 4 个 5V 电源提供给微处理器: 5M,5C,5R 和 5T。当电源

接通时，微处理器用的5M一直保持输出。5M虽然为经常输出，

但在关闭电源时也被关掉，防止微处理器出现故障状态。

5C 为公共的 5V，在非省电状态时保持输出。

5R 为接收用的 5V，在接收期间保持输出。

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.

(1) The red LED blinks when the battery voltage falls below the voltage (1) shown in the table during transmission.

Note:

The transceiver checks the battery voltage during reception even when, in the FPU, the Battery Warning status function is set to “On TX” (default setting).

However, the LED does not blink during reception. During transmission, the LED blinks to generate the warning tone of a low battery voltage.

(2) The transceiver immediately stops transmission when the battery voltage falls below the voltage (2) shown in the table. A message tone beeps while the PTT switch is released.

3) 电池低压警告

注∶

即使电池电压警告功能在 FPU 中被设置为“On TX”(默认设

定) ，手持机在接收时也检测电池电压。

但是在接收期间 LED 指示灯并不闪烁。发射时电池电压过低

LED 会闪烁并产生警告音。

ADJUSTMENT /

调整

■ The following parts are required for

adjustment

1. Antenna connector adapter

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.)

2. Repair Jig (Chassis)

Use jig (part No.: A10-4086-03) for repairing the TK-2207.

Place the TX-RX unit on the jig and fit it with screws.

The jig facilitates the voltage check and protects the final amplifier FET when the voltage on the flow side of the TX-RX unit is checked during repairs.

3. Battery Jig (W05-1011-00)

Connect the power cable properly between the battery jig installed in the transceiver and the power supply, and be sure output voltage and the power supply polarity prior to switching the power supply ON, otherwise over voltage and reverse connection may damage the transceiver, or the power supply or both.

Note: When using the battery jig, you must measure the voltage at the terminals of the battery jig. Otherwise, a slight voltage drop may occur within the power cable, between the power supply and the battery jig, especially while the transceiver transmits.

■ 下面是调整时所需的部件

1. 天线接口转换头

此手持机的天线接口使用 SMA 终端。

使用天线接口转换头 [ SMA ( f ) - BNC ( f ) 或 SMA ( f ) - N ( f ) ]进

2. 维修机架（机壳）

使用机壳（A10-4086-03）维修 TK-2207。将 TX-RX 单元放置

在机壳上，并且拧上螺钉。

在维修过程中，需要在 TX-RX 单元的电路板上检测电压时，

机壳可以方便地进行电压检测，并且保护模块。

3. 电池夹具 (W05-1011-00)

在手持机的电池夹具和电源之间连接适当的电源电缆，确认

了输出电压之后接通电源开关，电压超过或极性颠倒都有可能

损坏手持机。

注∶当使用电池夹具时，你必须测定电池夹具的终端电压。

因为，电源和电池夹具之间会有一些的电压下降，尤其在手持

机发射的时候。

• Preparations for tuning the transceiver

Before attempting to tune the transceiver, connect the unit to a suitable power supply.

Whenever the transmitter is tuned, the unit must be connected to a suitable dummy load (i.e. power meter).

The speaker output connector must be terminated with a

8Ω dummy load and connected to an AC voltmeter and an audio distortion meter or a SINAD measurement meter at all times during tuning.
