Make MW transmitter Using NE555   Using comments NE555 timer chip 330 ohms, 1K ohms resistance 0.001uF capacitor Condenser mic and 9V DC power supply. Power supply :-  Using supply only DC stable you can use 9Volt battery and smps supply And mobile adaptor unfortunately it is no 9Volt but approx 7V max. NE555 timer chip :- This chip number 1 pin Ground, pin 2 Trigger, pin 3 Output, Pin 4 reset, pin 5 Cout, pin 6 Three, pin 7 discharge, pin 8 VCC. Important notice this chip you cannot supply voltage 9 volt up otherwise timer cheap was burning. This chip integrated 2 op-amp or 1 SR flip-flop or one NPN transistor and voltage divider. Supply voltage minimum 4 volt up and maximum 10 volt. Capacitor :- Using capacitor 0.001uF this capacitor number 102. You can used any condenser mic MW frequency :-  Medium wave is the part of the medium frequency radio band used mainly for AM radio broadcasting. The spectrum provides about 120 channels with limite...

FM transmitter signal booster circuit Diagram This signal Amplifier (booster) work only FM band. Important notice you can you big antana and antana place teddies on your home. so your signal more than area of coverage this booster more than 10 km range. You can watch the video go my youtube channel. This circuit Diagram work frequency boost up low amplitude to high amplitude. You can not use MW and SW transmitter because this design for FM circuit only. Using transistor - BC547. You can use any of MHz frequency range transistor examples (BC548, 2N222 extra you can search google). Using capacitor 1uF ceramic capacitor. You can also use 1nF, 10nF, 0.001uF. capacitor place transistor or inductor maintain distance 1CM. You cannot maintain distance than your frequency more than noise added your signal. Using resistance 220K ohms and 10K ohms. Using incuctor made than use you screwdriver throttle 10 turn 20 SWG wire. Using powe supply max volt apply 15V but I am using j...
