I want to boost signal strength of this circuit. Can I attach a 1-2GHz UHF Amplifier Module(which are available in Market) at the end of this circuit to amplify it? Can I just take the antenna point as input for the FM Amplifier?
No,
Thank you for comment ❤️🙏🏻👍🏻
@@amkp40technology I was able to build the transmitter as per your schematic. My radio was an old Philips whose knob has ended just before 108 MHz, it doesn't reach 108 MHz. So, I did little adjustment - used a 24 MHz crystal and got my radio tuned in the range of ~ 95-96MHz and it worked just fine!! Thanks!
@@PrithwirajBose
Very good 👍🏻❤️🙏🏻
your Idea is good but after 2 ghz its not a radio wave any more now its microwave..for which you need real towers for signal transmission..
@@shivasisdash7343 hahaha
This circuit works with 4 harmonics. I already made this circuit. Any crystal in that circuit is just multiplied by 4. Thank you from Brazil.
Thank you for comment ❤️🙏🏻👍🏻
What is fourth harmonics? And where can i get details about it?
can u share your circuit diagram
Cool. I was thinking of making this. 😊
@@victorwando8950if you look up any "one transistor radio transmitter schematic" and just add the crystal across the base and V,in(the positives) but place after that input resistor it will work.. 😊
Thank you very much for video 👍

I'm from Brazil, I don't understand what the video says ... So I would like to know which resistors should I use for 3.7 v
You don't need to change anything, you can use in 4V DC.
Thank you 😊🙏🏻👍🏻
3.7 volt se 5volt se work karega
sir how can i make the pre amplifier circuit to make the audio work
So nice
Thank you 😊🙏🏻
Sir ji (1) fix frequency Fm receiver bhi bana sakte hai kya? Please tal
Jaroor kosis karunga.

Can I use bc547 transistor and 4.7uf capacitor or it can work with 3 volts please tell me
You can use BC547 transistor but you can't use 4.7μF 🚫
Make a New video and tell us where to add a mic ,, and make a receiver for this transmitter.
Thank you for comment ❤️🙏🏻
Mobile mn fm radio app use kren tu work kry ga?
Yr is sub sikhne ke liye kisi book ka link bhi dedo
This circuit is much better than you think because when I connected this circuit to 60V, it output over 3W of RF power
This circuit not for high watt or voltage 🙏🏻
@@amkp40technology I tried and it work perfectly fine!
@@amkp40technology but I’m tried and It worked perfectly even at 70V but the resistor seemed to can’t take that much power
Definitely your transistor will fail.
Nice project. Can I replace bc547 with 2n3904 or with 2n2222a?
Yes 👍🏻
Sir 1tranc metars kethna redio tun otha hi

Sorry 😔 no any translation option in YT Studio.
Aap isko ek pcb PE banakar Mike bhee lagake check kartha tho bahut acha hota dha.
Ji bilkul PCB mae banayuga.
You're on the fourth harmonic not the fundamental frequency. Nevertheless, good project.
Thank you for comment ❤️🙏🏻
Good! Ok now make radio microphone on crystal !
Thank you 😊🙏🏻❤️
wow amazing 👍👍👍
Thank you 😊❤️❤️🙏🏻👍🏻👍🏻
I used the mobile phone radio as radio receiver. It receives signals for a distance of 1meter. How can I increase the transmission distance.
Use long antenna, simply use single copper wire 10 feet to 20 feet.
@@amkp40technology
Thanks for your reply.
Currently I working on a compact device, Where lesser space is available. So in order achieve the longer transmission distance(100 feet). Is there any alternate solution without increasing height and length of antenna.
Bro i did built your circuit but how can i attach the mic to it so it can be finaly called a transmitter
You need connect first additional pre amplifier circuit with this. Follow my circuit diagram link in the video description bellow.
Thank you ❤️🙏🏻
Sir please make a fm radio receiver with LM386 and bc547

Thank you for comment ❤️🙏🏻👍🏻
@@amkp40technology kab banoge sir
can yo make a video on how to lock or unlock something like car key does
Yes I can do it.
Thank you for comment ❤️🙏🏻👍🏻
i used 2 * 22pf caps in paralel ,yes the radio of my phone detects it but no sound comes out only noise
Use pre amplifier.
which resistor can i use apart from.the 4.7k
Jut follow video description's diagram Link 🙏🏻
If I make that circuit can I use phone's radio to use this circuit? I don't have any radio just want make my open ended lab for semester so anyone can tell me can I use phone's radio to connect that fixed transmitter circuit?
Yes, no problem 👍🏻🙏🏻❤️
Ok thank u😊🙏🏻
Bro where can i attach a mic in this circuit pls reply
What is the model of the round transistor?
Carefully watch the video. 2N2219 Transistor.
Thank you for comment ❤️🙏🏻👍🏻
Thank you so much for answer
Great project. Where will be the audio input for a microphone? It' gonna be a walkie talkie right?
Follow my circuit diagram link in the video description bellow.
Thank you ❤️👍🏻🙏🏻
But I couldn't find it, can you please paste the links here
Base of the transistor is the audio input, but use a limiting resistor like 10K or something else to get the best audio without adding that resistor it can kill the frequency of the transmitter
Nice work bro i hve question can i use coil insted of that crystal u have used
No never 🙏🏻
Bro i have tried it works
Hey bro where can i get audio wire connections?
Follow description link 🙏🏻👍🏻
Can i use battery cells instead 12 volts battery?
Yes 👍🏻 no problem.
I want to use with 3.7 v, what should be the values of the resistors?
Watch entire video before comment.
Thank you for comment ❤️🙏🏻👍🏻
@@amkp40technology I'm from Brazil, I don't understand what the video says ... So I would like to know which resistors should I use for 3.7 v
Yes, you can use in 4V DC. But, range reduce.
Thank you for comment ❤️🙏🏻👍🏻.
replace the 100k resistor with a 47k for 5v but it works for 3.7v
sir trimmer ko hata kar cristal laga du to frequency set ho jayega kya? lakin tremer ka to 3 poin he.. cristal ka to 2 point he. to kaise kya kare. ek poin ground ka hoga shayed. or mera transmitter me 2 tremer he. to kya me 2 cristal use karu?
Ji bilkul nehi, depend karta hai aapki circuit design kesa hai ussko dekh kar hi bola ja sakta hai 👍🏻❤️🙏🏻
Can I use 104pf or 10pf to replace the 47pf
No.
3 v ki battery use kren tu kia range hogi?
Lag bhag 3 meters.
Questo funziona con le armoniche. Non è un trasmettitore a 108.
Can i use bc 548 transistor
Yes, Try.
Thank you for comment ❤️🙏🏻
fm transmitter stereo high range ke agar aap bana skte ho kya ? agar aap bana sakte ho toh mai interested hu usko buy karne ke liye .
aapse kaise contact karre
Mae kosis kar raha hoon isska range improve karne ka.

Thank you for comment ❤️🙏🏻👍🏻
Can it work with 3to5volts input
Yes.
Can I use 32MHz crystal?
No,
If you use 32Mhz crystal output frequency definitely change higher than 108Mhz , that's means you can't receive the frequency in FM band radio.
You can use 25Mhz or 16Mhz crystal.
Thank you for comment ❤️🙏🏻👍🏻
can i use 26 mhz crystal osilator
Yes 👍🏻
How meters will it work from5volts
4 meters. 👍🏻🙏🏻
Can I use 16Mhz crystal
Yes, but range reduce.
Thank you for comment ❤️🙏🏻👍🏻
I'm use s8050 transistor but dont work :)
I dont have now bc547
Connect correctly and try again.
Thank you for comment ❤️🙏🏻👍🏻
Aawaj to testing karo bhai.
Aawaj ko bhi testing karchuka hoon, aap logoko banamae aasani ho issliye audio input ka section nehi dala, circuit diagram mae jake dekh sakte hae iss video ki description mae hai 👍🏻🙏🏻❤️
Hello freand 📶 I think the distance is longer with a gain antenna.
Not too much 😌
Please tell the made own network service
Yes
Sir Audio not transmit problem plz help ..
Use a pre-amplifire circuit.

@@amkp40technology Bhai aap sahi kaha Radio ka maja hi kuch aaur hai..jo ki smartphone ke jamane me nahi..🙏
Thank you so much sir ....sir can we do it this without any cost or any without registered of frequency band in nepal?
What do you mean?
@@amkp40technology fm transmitter is free or it should be registered for frequency band
Short distance FM radio frequency free to use almost every country.
the circuit worked for me, but I can't transmit audio at the input
You can transmit audio but output gain is very low.
where to solder aux 3.5mm?
Follow description diagram link 🔗🙏🏻
Sorry for commenting but sound input is not working as per your circuit diagram. Please correct your circuit diagram or I have to agree that this module not work in transmitting sound signal
Working, but sound is low, you need to connect additional preamplifier circuit.
Thank you for comment ❤️🙏🏻
How will that pic audio signal,without microphone
