TK-7 1 60 8 6. Accessory Connection Cable (KCT-39) The KCT-39 is an accessory connection cable for connect- ing external equipment. The connector has 15 pins and the necessary signal lines are selected for use. 6-1. Installing the KCT-39 in the Transceiver 1.
TK-7 1 60 9 7. Ignition Sense Cable (KCT-18) The KCT-18 is an optional cable for enabling the ignition function. The ignition function lets you turn the power to the transceiver on and off with the car ignition key. 7-2. Connecting the KCT-18 to the Transceiver 1.
TK-7 1 60 10 5. Affix the 20 x 20 x 2.5 mm pad to the 40 x 33 mm transpar- ent sheet, then attach it to the TX-RX unit printed area as shown in Figure 3. IC281 q w G11-4353-04 (40 x 33 mm) G13-2065-04 (20 x 20 x 2.5 mm) 6. Affix the 30 x 30 x 1 mm pad to the top of the KAP-2 relay unit.
TK-7 1 60 11 INST ALLA TION / DISASSEMBL Y FOR REP AIR 2. External Speaker (Option) 2-1. KES-3 The KES-3 is an external speaker for the 3.5-mm-diameter speaker jack. ■ Connection Procedure 1. Connect the KES-3 to the 3.5-mm-diameter speaker jack on the rear of the transceiver.
TK-7 1 60 12 Frequency Configuration The receiver utilizes double conversion. The first IF is 49.95MHz and the second IF is 450kHz. The first local oscil- lator signal is supplied from the PLL circuit. The PLL circuit in the transmitter generates the necessary frequencies.
TK-7 1 60 13 ■ Wide/Narrow Switching Circuit The Wide port (pin 23) and Narrow port (pin 22) of the CPU is used to switch between ceramic filters. When the Wide port is high, the ceramic filter SW diodes (D332, D331) cause CF301 to turn on to receive a Wide signal.
TK-7 1 60 14 ■ Unlock Circuit During reception, the 8RC signal goes high, the 8TC signal goes low, and Q44 turns on. Q43 turns on and a voltage is applied to the collector (8R). During transmission, the 8RC signal goes low, the 8TC signal goes high and Q46 turns on.
TK-7 1 60 15 Control Circuit The CPU carries out the following tasks: 1) Controls the WIDE, NARROW, TX/RX outputs. 2) Controls the AQUA IC (IC241). 3) Controls the PLL (IC401). 4) Controls the D/A converter (IC201) and adjusts the vol- ume, modulation and transmission power.
TK-7 1 60 16 ■ Decode The signal goes to EXTLIMIN (pin 5) of AQUA IC (IC241). The QT/DQT signal will pass through the low-pass filters in the AQUA IC (IC241) and be decoded within the AQUA IC (IC241). The DTMF signal will be decoded within the AQUA IC (IC241).
