Very very thank you bro it really worked and it's sound is also very clear but my transmitter don't work in mobile but perfectly worked in actual radio it by auto tuning i found my frequency 85.9. my fm transmitter range is 10m because of 7.5v power supply. it is worth making it will not be in first attempt but it it requires multiple coil and pacence time
Thanks for sharing your experience ❤️❤️❤️
Can you make one video on it ?
Use 9 volt and battery
@@sm_electronicsbrother one doubt can I able to change quarter watts resistors to all in half watt resistor without changing other components
Me too worked 🙏
it works perfectly
lots of thanks dude🙏🙏
Thanks for the comment,it gives me wings...
😳😳😳👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻 MUINTO BOM BEM EXPLICADO 🇧🇷👍🏻😊✨🇧🇷
So faltou explicar a falta do capacitor variavel junto da bobina né?
অনেক অনেক ধন্যবাদ,এটা কাজ করছে।
ধন্যবাদ আপনাকে😊😊😊
very impressive ..Nice job
add 5 or 10pf capacitor across the coil legs.
Onek video dekhlam sob theke easy ei video ta pelam
ধন্যবাদ।
हेल्लो भाइ आपका भिडियो बहुत अच्छा लगा मुझे ।और नया प्रोजेक्तका भिडियो दाल्ते रहिए धन्यबाद। me from pokhara nepal.
thanks friend
Greetings from Egypt

i have to show the wave form in oscilloscope, so tell me where should i input the carrier signal?
Maybe in the collector pin.
How do I add a phone jack instead of the mic? Does the value of the resistors change?
Or I can add a headphone mic
Remove the 12k resistor.
Phone jack + to 104 of cap
Jack - to 0v or gnd.

I do not understand the electrode - how it is connected, explain further
Whats the gauge rating of copper wire you used ?
I used same circuit but it's not working ?
Try Another Coil. Use Radio Receiver.it is 0.5 to 0.6mm wire.spread or squize the coil.
I used an 8pf capacitor and instead of a 27 kilo resistor, I used 32 kilos, does it work??
Yes...
@@sm_electronics
I tried the circuit and succeeded, but its distance without an antenna was only two meters
Which frequency did you get and how do the coil affect the frequency, does more turns equal higher frequency?
Coil wire diameter and number of turns affect the frequency.
@@sm_electronics more number of turns equal higher frequency?
Maybe Yes...
More number of turns does not equal more frequency due the fact that the inductance increases with more turns
@@sm_electronics sorry but it is not correct
Hi friend could you tell me please if capacitor 10 Microfarad will work because I didn't understand 12 k ??
Resistor 10k and Capacitor 10 uf will work.
Hi friend can I use adapter charger instead of battery ?
Use Battery for less noise.best of luck...😀😀😀😀
Hi friend I hope you good does 6 volts battery works or not? And thank you ?
Main part is coil.6v works best.
When i use a frquency generator, i hear the frequency at 107,5MHZ, but my mic dosent work, can the problem be the coil, or do i need a amplifier curcuit besides to get stronger signals from the mic?
squeeze the coil to get lower frequency
Good
Thanks 🥰🥰🥰
which frequency will it use for transmission ?
About Middle of the Band. It depends on the coil.So It vary.
@@sm_electronics AM Band ?
Fm band
Can I use a resistance of 4.7K Replacement resistance 470 ohm
Use 220 to 560 ohm. 4.7k is very high value.
Can i use any capacitor for reducing noise in this circuit
yes use 100uf capacitor between positive supply and 0v.
use 5pf or 10pf between coil legs.
Hi brother I did the same as you did but It didn't work with me ? Could you please advise me to do something ?
Try changing the coil.spread or squize the coil.coil is the main part.
How meters it's range after adding antenna
70-80 meter with matching antenna and coil.
Does it have a specific range and distance?
Yes ,with a good antenna and good coil it can cover good distance.
Nice and what if you just connect wire speaker instead of the mic will be working??
it is a transmitter, not receiver
@@sm_electronics cool I mean if you put line in instead of the mic
music will be transmitted
@@sm_electronics thank you let try to see if it will work through my phone radio
Menga yoqdi
Thanks 😊😊😊
with what can i remplace 27k resistance ?
33k or 47k
@@sm_electronics thanks
What mic do you use
headfone mic
I have neighbour they used to loud their fm speaker ! Will it work on them ?
They have to set any frequency or it automatically connect radio
they have to set frequency
Do you have any solution for this problem
this is the way it works.
I will be greatfull to you if you give any solution for this problem ?
i coppied the circuit exaclty and put it on a pcb but the sound or frequency/signal is not stable i need to hold it or constantly move the circuit like its looking for a signal for the reciever to produce the sound and if not there is only noise that is heard. how to deal with this pls thank you
use good battery for power supply.
use a antenna. send me your circuit.

Cikisa seri bir 547 yi beyzine 100 pf veya 470 veya 1 nf ile girip tetik için 27k kollertor ise bur kac tur bobin + ya cikis ise 27 100 pf ile anten biraz daha mesafe artar diye düşünüyorum
thanks for the comment, do experiment.
hope some time before, at the output of the FM transmitter, I lit the lamp, even if it was tiny.
insallah bi ara daha önceden fm vericide çıkışta Lambayı minicikte olsa yakmıştım
Hello , can I use H331 transistor
use NPN transistor, Google the transistor number
با درود،انصافن اگه واقعن تا این فاصله رو ساپورت کنه نسبت به تمام کلیپهای ساخت میکروفن که تا الان دیدم با اختلاف پیشتازه،اگه کار بده واقعن دم طراحش گرم
thanks for the beautiful comment.
Can I use 330 hom resistor
Yes...
Hi friend ; Can I use a capacitor other than 10p
Use low value like 4.7pf
😊😊😊😊 FM transmitter
Thanks 😍😍😍
Can I use 33k resistance instead of 27k resistance
Please reply
Yes
What difference does it creates

How can I calculate the frequency, sir?
electronics.stackexchange.com/questions/33435/how-do-i-calculate-the-frequency-of-an-fm-transmitter-circuit
just 1 question...is it able for 2 or more to receive the transaction?
i don't understand your question. please say more clearly.
@@sm_electronics ok..my question is. if i have two FM radio which are tuned to that same frequency. will both of them work. (receive the signals)
yes. 2 or more radio will receive same signal.use a capacitor of 5pf or 10pf between the legs of the coil.

Nice comment 🥰🥰🥰
what is receiver frequency?
In the FM Band
what do you mean with 12k use 4.7k to 10k ???
Use 4.7k to 22k.
@@sm_electronics thanks for your help
Can i use my phone fm to capture frequency
yes.
Can i use the bluetooth headphones instead of mic?
You can get mic inside of a headphone
Can i use aux cable without mic
yes... but remove 12k. give aux+ to 104 pf capacitor and mic negative to aux-
Bc547 yerine bc237 kullanırsak olurmu
yes.same pinout
So nice
Thanks 😊😊😊😊
how can i make 3000khz transmitter i went long range radio webe can you help me about this
Sorry no idea bro🤔🤔🤔
@@sm_electronics i went to make a sattlite so need long range radio transmitter
Van we use 1000pf capacitor
Use 10pf or lower.
Can I use 2n2222 transistor???
Yes. See the pinout
It is Emitter-Base- Collector
@@sm_electronics thanks
can you make a video on how to make FM receiver very simple with BC547?
I will try🥰🥰🥰
It's don't work on mobile?!!?
It works on mobile.use dc supply and experiment with the coil.
Can i use 9v battery?
Use 9v battery.
How far is it?
How can we add an antenna on it
Add antenna on collector pin
About 100 meter range with good antenna and 9v.

Brother, what is the use of crystal oscillators and an IC for this circuit?
how make a fm reciver with single transister and some componets.

Can i use speaker instead of FM..?
no
One transistor on FM range 10m
no . using antenna you can get more
Bro is it really working ??
Yes It has good range.

I can use. 1 k near 4.7 k to 10 k
It is for mic.You can use but use High value.

i don't have 10pf capacitor
use 5 pf or anything between 5pf-10pf
@@sm_electronics for me this circuit not working build properly but no response used 9v battery as a input 10pf capacitor
use a radio to receive signals

try with different turn coil.
