83002 – 9.6V Dub City TX Block Diagram Buffer Modulated Amplifier Oscillator (Carrier) Modulator Driver (TX-2C IC) Battery DC9V 49.86MHz Crystal Antenna

FCC ID Label Sample FCC ID: TB7DXTOYS50349 This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

Assortment No: 83002 Project: 9.6V Dub City Radio Control Car Frequency: 49.86 MHz Rev: 00 CIRCUIT DESCRIPTION IN TRANSMIT MODE: After TX unit is switched “ON” and press either K1, K2, K3 or K4 the transmit frequency is oscillated by X101 and mixed with the encoded signal from SO port (pin8) of U2 by Q101 then coupled through T101 to antenna. The low pass filter made up of C108, T101 & C109, which is connected to the antenna. A 9V Alkaline Battery supplies energy. IN RECEIVE MODE: The receiver part is using a Supper regenerator circuit and Q1 is the Supper regenerator & detector, D1 is the precision voltage regulator, U1 is the signal decoder. Q5, 6, is the tunnels of the motor driver. JK1, JK2 (Relay) is the power control of the Forward / Backward motor. Q13, 14, 15 & 16 is the current driver of the left/right motor. Energy is supplied by 9.6V rechargeable battery. ANTENNA GROUND CIRCUITRY This unit makes use of an external 20-inch rod antenna, the antenna is inductively coupled, the unit relies on the Ground trace of the circuit board. No external ground is provided. A 9V alkaline battery supplies energy.
