• Do not modify the radio for any reason. Use only HYT original batteries and chargers. Use only the supplied or an approved antenna. Do not use any portable radio that has a damaged antenna. If a damaged antenna comes into contact with your skin, a minor burn can result. • Radio Overview TC-610 ① PTT ② SK1 (programmable key) ③ SK2 (programmable key ④ Speaker ⑧ Channel ⑤ Microphone ⑥ Antenna ⑦ LED Selector Knob ⑨ On-Off/Volume ⑪ Earpiece Jack ⑩ Battery Latch ⑫ Earpiece Cover Control Knob Programming Port ⑬.

Your dealer can program the key with a function via the programming software. Side key 2, programmable. Your dealer can program the key with a function via the programming software. LED statuses and alert tones: Power on the source radio while holding down the SK2 key. • LED glows red.

When transmission times out, “BEEP” tone sounds Transmit continuously. TOT pre-alert: “BEEP” tone sounds once. Receive When a carrier is received, LED glows green. When detecting, LED flashes green every second. Connexions methode de francais pdf to excel. Scan start tone (programmable by your dealer): “BEEP” tone sounds once. • Turn the knob clockwise to increase the volume, or counter-clockwise to decrease the volume. Software Specifications Functions 1.

Available Channels: 1 to 16 channels Frequency Range: UHF: 400-420MHz UHF: 450-470MHz 2. Channel Spacing: 25KHz/12.5KHz 3. Channel Step: 5/6.25/10/12.5KHz channel scan function 4. • Circuit Description Realization Methods for Basic Functional Modules PLL Frequency Synthesizer The PLL circuit generates local oscillator signals for reception and RF carrier signals for transmission. The PLL circuit consists of the VCO oscillator circuit and baseband processor chip and realizes frequency tracking and channel conversion under the control of MCU signals.

• U202 generates a control voltage via the phase comparator to control varactors (D100 and D101 in transmitting mode; D102 and D103 in receiving mode) to bring the oscillator frequency of VCO in line with the preset frequency of MCU within a broader frequency range. The switching tube Q652 switches between transmitting and receiving under the control of T/R. • TUNE FROM MCU TUNE FROM MCU Q500 C521 C524 C505 D505 D507 D506 D503 D504 C526 C523 C506 C519 C504 L508 L507 L506 L502 L501 TUNE BPF TUNE BPF Figure 4 The Rx signals input from the antenna is filtered to remove out-of-band signals at the electrically tunable bandpass network (D503, D504, L501, L502, C503, C505 and 507) and then amplified by low-noise amplifier (LNA) Q500 to obtain a certain level required by reception. • is utilized. The mixer tube (Q501) utilizes dual gate FET MOS (3SK318) and has better noise characteristics and square law characteristics.

The isolation between the local oscillator signals and the Rx signals is high. To ensure proper sensitivity and certain gain for the mixer tube, tune delicately via the offset. • Audio and Signalling Processing Circuit Baseband processing IC AN29160 has high integration level and powerful functions. Many of the processing functions (as VCO level detect&output, SQ signal level detect&output, Tx-Rx audio processing switch, audio amplifier, etc) and can be realized inside. The Tx-Rx sharing can also be realized.
