WHEN THE CONTROL KNOB IS PRESSED, A CW SIGNAL IS TRANSMITTED. THE CRYSTAL CONTROLLED OSCILLATOR Q1 OUTPUT IS COUPLED THROUGH C7 TO THE BASE OF Q2,FROM Q2 THE SIGNAL IS FED THROUGH T-1。 THE LOW PASS FILTER MADE UP OF C12 & T-1 & C1 L-1 WHICH ARE CONNECTED TO THE ANTENN。 THE 'MODULATION IS PROVIDED BY U-1 .WHEN SWITCH IS PUSHED, THE MODULATION SIGNAL WILL BE SENT TO THE BASE OF Q1 THAT WILL MODULATE THE RF WAVE DIRECTLY,Switch stay 45 Seconds U1 Automatic OFF ,A RESET SWITCH S1 IS PROVIDED TOO. ENERGRY IS SUPPLIED BY 6F22=9 VDC ALKALINE BATTERY. ** TYPICAL OPERATION TYPICAL OPERATION WOULD INVOLVE THE USER TURNING ON THE UNIT TO THE TOY GAME. WHEN TURNED ON, THE UNIT COMES UP ON THE DEFAULT CHANNEL AND TRANSMITS A CONTINUOUSLY STEAM DATA. THE USER CAN NOT, AT WILL, CHANGE TO ANY OTHER OF THE PREDEFINED CHANNEL. ** CONFIGURATION THE TRANSMITTED RF CIRCUITRY CONSISTS OF A CRYSTAL CONTROLLED OSCILLATOR, FOLLOWED BY ONE POWER AMPLIFIER, & FINALLY, AN ANTENNA. THE MAIN CHARACTERISTICS OF THIS CONFIGURATION ARE SHOWN BELOW :- ** FREQUENCY RANGES 27.145MHZ OCCUPIED BANDWIDTH (3DB) +/-2KHZ MAX FREQUENCY STABILITY +/- 20 PPM MAX MODULATION METHOD A M 100% . OUTPUT POWER 80DBUV / M MAX ** REFERENCE OSCILLATOR A 27.145MHZ CRYSTAL OSCILLATOR IS USED TO GENERATE THE REFERENCE FREQUENCY IT HAS A STABILITY OF + / - 20 PPM. ** AMPLIFIER THE OSCILLATOR IS FOLLOWED BY ONE AMPLIFIER. THIS ACTS MORE AS BUFFER FOR THE OSCILLATOR THAN AS GAIN STAGE. AND ADD VERY LITTLE POWER TO THE SIGNAL. THE FINAL OUTPUT IS 80D BUV PER METER MAX ** ANTENNA THE SYSTEM ANTENNA IS A ANTENNA ROD LINKED TO PCB .
