hello audio guru i can only get very commonly used american IC s here . i ll prepare that transmitter in one week and tell u the results. u havent told me about coils i have prepared with enameled copper wire used in motor winding .are they going to be work properly...rest of parts except lm2931 are available of good quality so tell me substitute for that .. i have my own LCR Q METER TO TELL THE EXACT VALUES FOR COIL BUT PLEASE tell me how to mak these perfect also tell me the range for that transmitter(value for C4 to get maximum range) here there is no licencing problems for students like me .and i have not to use the transmission for music.i need this to send some DTMF s and encoded digital signal... . i ll also use same for monitering my room in absence....so please guid me to make a good fm transmittter since i have to make several projects based on it. regards.

hello and thanks audioguru for guidline. now i ll prepare it on pcb.but can u tell me my coils are ok or not about which i have asked earlier.and u r saying it is an old circuit so please suggest a new circuit for fm transmitter ranging 1.5-2 km.i ll try that old circuit also but prefer the new one provided by u.it will be really helpful.

hello everybody. i need your help here . i am making a fm transmitter of range 1 km .schematic is attached .now problm is that it only amplifies the input signal not do modulation. i think problem in osilator. can u tell me how to make proper coils since i m using copper wire which i have bought from a motor winding shop.and for capacitor i m using trimmer (0-50)pf . please help me out .u can send me another tested schematic also whose range is about 1.5 to 2 km. i have no license problem here :-\

i m having license up to 10 watt so no need to be afrraid of and i am having whole equipment to make own pcbs so i dont want to buy a kit. please forward me a schematic

com on guys 2 days passed but no reply please do it

happy new year guys! please help me. i want to build a fm transmitter for radio transmission in my college campus and got so many schematics.but i m confused regarding their ranges.actually i need a stereo fm transmitter having a range of minimum 1 km (with in surrounding buildings ).frequency stability is also matters much.please send me a fine tested circuit .
