Hi audioguru,
so it's a colpitt's oscillator.. but how can you say that it is a very poor fm transmitter..?? honestly, it's working perfectly for me, transmitting at 105.5 MHz. The sound was very clear and it has a very long range..
also, i wanna ask something. when i finished it, it's working at 107MHz, using just a 3inch wire.. but when i added an antenna (i get it from an old nonworking radio) it shifted to 105.5MHz. there is no change in the quality of sound. why is that??
i also noticed that when my input is from an electret mic, it seems that the mic is very sensitive that i can even hear from a receiver voices and sounds of almost everyone around the transmitter (all are clear). how can i lower its sensitivity??
btw, thanks for your reply..
