    TC-600 Brief Introduction Brief Introduction Antenna Used to transmit/receive signals. LED Indicator The light will glow red during transmission and glow green during receiving. During transmission, the light flashes red when the battery voltage is low. 3. Channel Selector Knob 4.
  • Page 4 TC-600 Brief Introduction 9. External Jack (for external earphone or radio programming) Rotate the jack cover and insert accessory plug, or insert programming cable into the jack to program the radio via programming software. 10. Battery 11. Belt Clip Used to clip radio on your belt.

  • Page 5: Software Specification

    TC-600 Software Specification Software Specification Radio Feature Description 1. Use Channel Selector Knob to choose from 15+1(Scan) channels 2. Monitor 3. CTCSS/CDCSS Encode & Decode CTCSS: 38 groups CDCSS: 83 groups 4. Wideband (25KHz) / Narrowband (12.5KHz) 5. Channel Scan (Priority channel and Revert channel available) 6.
  • Page 6 1. User Mode User Mode is for conventional communication operation. Disconnect the two SELF points and then turn the power on, the radio enters User Mode. (Refer to ―TC-600 Owner’s Manual‖ for detailed operation description.) 2. Model Set Mode Select MS1 according to the radio model.
  • Page 7 TC-600 Software Specification Turn off the power and then disconnect the two SELF points to complete the model setting. For example, MS1 of TC-600U (450.000~469.995MHz) is 0 and its model is 7(Refer to ―Initial Data Table‖). To initialize its model and channel data, you can operate as following: ●...

PC Adjust Mode The following settings can be adjusted through the programming software: Low battery alert level SQL9 SQL3 CTCSS deviation (wide) CDCSS deviation (wide) CTCSS deviation (narrow) CDCSS deviation (narrow) 5. Manual Adjust Mode If Manual Adjust Mode is enabled, turn on the power while holding down [PTT] and Function Key simultaneously, the radio enters Manual Adjust Mode in 2 seconds.
  • Page 9 TC-600 Software Specification CH12-CH16 are used to adjust transmitter and receiver. Press [PTT] to transmit; release to receive. In receive mode, short press the Function Key to toggle among high and low power, or long press it to switch between wideband and narrowband. Three Beeps alternating from high tone to low tone indicate that the transmit power is switched from high to low;...

  • Page 11: Circuit Description

    TC-600 Circuit Description Circuit Description 1. Frequency Configuration The receiver utilizes double conversion superheterodyne. The first IF is 45.050MHz and the second is 455 KHz. The first local oscillator signal is supplied from PLL circuit. Frequency needed in the transmitter is supplied from PLL circuit. Figure 1 shows the frequency configuration.
  • Page 13 TC-600 Circuit Description Figure 2 Receiver Section Configuration 2) The First Mixer The signal from RF amplifier is mixed with the first local oscillator signal from PLL frequency synthesizer in the first mixer (Q23) to generate a 45.050MHz first IF signal. The first IF signal is then fed through two monolithic crystal filters (XF1) to remove spurious signals from adjacent channels.
  • Page 15 TC-600 Circuit Description FM IF IC1 AF/PF AMP IF AMP 39 40 IC11 Figure 3. AF Amplifier and Squelch Circuit 6) Receive Signaling CTCSS/CDCSS Over 300Hz audio frequencies of the signal output from IC1 is cut off by a low pass filter. The resulting signal enters the microprocessor IC11.
  • Page 17 TC-600 Circuit Description Figure 4 PLL Circuit 2) VCO The operation frequency is generated by Q16 in transmit mode and by Q8 in receive mode. The operation frequency generates a control voltage through the phase comparator to control the varactor diodes, so that the oscillator frequency is made consistent with the preset frequency in CPU (D2 and D3 in transmit mode , D7 and D8 in receive mode).
  • Page 19 TC-600 Circuit Description 3) DTMF/2-Tone Encoder DTMF/2-Tone signalings are generated by IC11 and outputted in parallel by Pin 48-51. The output signal is reshaped by resistor array CP7-CP10, then sent to IC3 (1/4) for amplification, and filtered by active LPF consisting of Q25, Q24 and other components to eliminate the corresponding HF emission before being passed to TX VCO for modulation.
