 This is DJ Rocky Nel the site owner.in first i have an small FM transmitter experiment in early years ago 2005.In my own experiment circuit design.in may 21 2006 i also work of another small FM transmitter it is a mill-watt FM voltage control oscillator in my work. i try to test on air in my home.i think the signal is very weak.But also it is not Difficult to get the signal faraway a miles from my home experiment..i do a basic dipole antenna in i using a rg58 coax cable.my antenna is 12meters above the ground.The signal propagation is about 2-3klmtrs.radios in a line of sight area.in the next two weeks i add another RF transistor in it is a upgrade the signal up to 1 watt level....... In July 2008 i start a test on air.running with my audio equipment,mp3,mixers,audio limiter.and other music associated unit to V.C.O. Fm transmitter.but the case of freq.problem is drifting so i think this is a not good circuit,the freq.is unlock as will. My friends in down town Goa comments about the freq.of my transmitter work is changes 5khz .will in finally i do a very hard work home made Fm transmitter modified with the PLL or Phase Lock Loop and stereo digital Fm transmitter.My Rf Amplifier is using a BJT Biasing.this is a small medium part of electronics computation and formula to how the transmitter is working..More E C E student ask me about that matters.This is a very hard work . how to do basically? and how operates technically.?..so i do to answer that questions .... So thank you so much guys..i hope you have interest to do my hobbies!!! But remember.all you have to do is need to get an N.T.C.
