faizanbrohi Posted September 10, 2006 Report Share Posted September 10, 2006 Here is a PCB layout and shcematic for my latest TX-500 500mW FM Transmitter i am building for my RC Remote controlled car using DTMF Signals to control it . I have not build it but this will hopefully be my 3rd transmitter project . from 40mW and 10mW to 500mW . Well hope this works . I found the schematic on www.electronics-diy.com and then redrawned it and made a PCB . Later i will make the Reciever and the DTMF Encoder and Decoder. THere is one problem the 4.7uF capacitor is i think a non polar and the 47uF is also a non polar capacitor but well i can go with a 4.7uf to be non polar but a 47uF , i don't think so or it might be bipolar. The Red connection on the PCB Layout is for a jumper that was not routed correctly . it might be connected on the bottom side using insulated copper wire.
