TOY WALKIES TALKIE 50 MHz WITHOUT CRYSTAL

hello to all radio hobbies and electronics enthusiast i am sharing my little electronics knowledge       about topic of toy walkies talkies radio transceiver 50 megahertz i made my own drawing schematic diagram in toy walkies talkies 50 megahertz without crystal is surface mount technology                  

schematic diagram toy walkies talkie new version  

inside view in toy walkies talkie was shown small pcb with power switch and ptt knob,speaker, rubber ducky antenna and battery holder 

  

    (PCB) printed circuit board upper side or parts placements shown T1 inductor transformer you   twist for adjustment high and low of frequency Q1 S9018 transistor is rx and tx radio frequency oscillator L1 is radio frequency coil 1.5 micro henry SW2 is (PTT) push to talk 12 pins SPDT switch without spring lock, SW1 is on and off power switch and two electrolytic capacitor the value is 100 micro farad 16 volts

       

printed circuit board bottom view copper side is surface mount technology very tiny parts is not easy to fix without schematic diagram that why i am sharing my drawing schematic diagram for guide for fixing this toy walkies talkies 50 megahertz
