Good communication distance !
good working
Thank you ❤️🙏🏻
Que bien felicitaciones
Nice
Thank you ❤️🙏🏻
Incrível...
Legal ❤.
El transmisor puede servir de intercomunicador si se hace un par
And 56pf other options 😢
47 pf
Please, I just have a question: is the modulation deep, clean and clair, as the commercial FM stations' one are? It's because, as we know, quartz oscillators don't allow a large frequency deviation, due their high quality factor, "Q", wich give them their characteristic stability and precision of frequency - and this the reason why PLL circuits are used for those devices. Thank you!
Now I've watched what happens: this transmitter of yours is a free oscilattor one, the crystal works as an simple capacitor, and this is the reason why the frequency changes all the time - and, in fact, if the quartz crystal could works as a real one, you would tune the transmitter, by the small FM radio receptor, at 108 MHz, wich is the fourth harmonic frequency of a 27 MHz quartz crystal, in instead of about 100 MHz, that were showed by its dial!
Then, I'm so sorry, friend, but your transmitter is not a quartz crystal one, 'cause it equates to a LC one - and this explains why it has an audio too deep, wich never would come from a quartz crystal one! So, the only solution is make a PLL FM transmitter, whose reference is the crystal oscillator for stabilize a LC oscillator.
This circuit not fully crystal based, here I am using this crystal for semi stability of frequency as like capacitor.
Thank you for your valuable comments 🙏🏻
hi... three questions. ...Can I use AUX for a smartphone instead of a microphone? Is it possible to use 5 volt USB charging instead of 18650? How to transmit a signal to a certain frequency, as well as with the possibility of changing it?
Yes 👍🏻 both possible.
You can change the frequency by changing the crystal's value
Vou construir este circuito. Se ru conseguir, falo aqui.
Please. Give diagram of coil connecting to collector and positive terminal
Please can i use BD 139 transistor ...will it work
No
Sir 6v auto cut off battery charger circuit banaye request please
Sir.... Crystal aur jayda MHz ka lga sakte hain, is se kya effect padhe ga?
Frequency badal jayega or range kaam yada ho sakta hai 👍🏻
Thanks for quick reply.... And one question aur sir... 56 pf nhi mil pa rha to dusra kaun sa lga skte hain mere paas 7,8,15,22, 68 ke hain.
*68pf isstemal karke dekh sakte hai 👍🏻 or ek baat iss circuit mae Transistor ka Collector pin mae ek coil isstemal kare tao eae sahi se kaam karega 🙏🏻 mae shirf coil less video title dene ke liye hataya hoon.*
One question if the crystal oscillator is 25 does it still work?
Yes, 👍🏻
Que tal si en el colector usas un circuito tanke sintonizado a 108MHz?
Como se puede correr un poco la frecuencia, a 108,1 Mhz por ejemplo?
у меня такой же вопрос. Для нечётной американской системы
16mhz ?
Can a 50pf capacitor be used?
You can try 👍🏻
ap pls ye sab or vi high quality se banaiye ga.💖
Jese? 🤔 Kon si cheez?🤔
@@amkp40technology jese, microphone or aux input switch....or frequency switch coil ke bina, lekin crystal rehega.
Can i use aux audio with out mic ???
Yes
is it possible to receive the signal by another phone's fm radio?
Yes 👍🏻
@@amkp40technology please do the experiment with your circuit and check whether the signal is received by phone or not.....then please inform me
Yes 👍🏻 100% receiving. Already tested.
@@amkp40technologyat which mhz can I receive this signal of android radio ?
भाई साहब एंटीना की हाइट अगर 25 30 फिट कर दी जाए तो इसकी रेंज बढ़ सकती है क्या इसके द्वारा और ऑडियो के अलावा क्या क्या पहुंचा जा सकता है कृपया बताएं
रेंज और थोड़ा बरेगी, क्यू कि ए बहुत कम वाट का हे। ए फ्रिक्वेंसी सिर्फ ऑडियो के लिए ही सही है लेकिन मॉडिफाई करके एनालॉग वीडियो सिग्नल भेजा जा सकता है। 🙏🏻❤️
Falta el receptor con salida rca para conectar a cualquier equipo
Where did you put the connection of antenna?
Red wire 👍🏻
at which mega hertz can i recieve the signal on anroid radio
108.0
No, frequency unstable 🙏🏻
I tried this and am unable to receive the signal on my radio
Use my another circuit, 👍🏻 video available in this channel.
can i use 16 MHz crystal?
No❌
Can i use bc548
Yes 👍🏻
🤷I can use 56pf otherwise 47pf
Use same which I mentioned in this video.
👍ok thanks
Not getting 56pf ceramic condenser please suggest substitute
will this work on AM band radio
No, only FM band radio.
@@amkp40technology one question?
why long copper wire between the battery and the circuit, plz explain??
It’s acting as the coil !
Sir,, crystal 27mh or What Replace. Ples say to. me..
I have 20mh cristal
I have 20mh cristal
Yes, you can try.
I suggest you for use a coil between transistor's collecter pin and resistance+crystal+positive input point. 🙏🏻👍🏻 For stability.
Frequency kitni hogi ya fix rhegi
Components ko touch karne par eya antenna lagane par frequency badal sakta hai 👍🏻
Fixed nehi hai.
100metter dur se voice recod kar sake redio ke maadhyam se bana sak te he cleear voice kuch hingsa nechar ke log baste he unki voce recod kar ke thaana me sabmit kar sake waci jugad bany ye kripaa kar ke
Ji bilkul 👍🏻 high Quality mae sunai deta hai Radio mae.
Can I use a 10 MHz crystal or is a 27 MHz crystal necessary?
No,
Yes 👍🏻
After using the 27mhz crystal I can't pick up anything on the radio, even putting the microphone close to the radio. 😥
Need Coil between transistor's collecter pin and positive input.
it is not 103 pico capacitor but 10 nano...
Yes 👍🏻 Right.
can i use 26 MHz crystal osilator
Yes 👍🏻
i cant recieve the signal and i have done evrything as in the circuit diagram what can be the problem.sir
Properly follow my instructions, otherwise use a Coil
fm transmitter 20 km edit
Wow
اذا لم اجد مكثف 56ماهو البديل
Please comment in English.
I can't fin 56 capacitor please tell alternative?
انا اقصد ماهو البديل للمكثف 56pf
No, alternatives 🙏🏻
Fixed 27Mhz FM TRANSMITTER....!
No, variable frequency 🙏🏻
Xtal very consistenf in this frequency..Your receive harmonic only...
i have noisy neighbour so can i use it for them ?
😀😊😊😊
But how it can apply ?
Is it automatically connect to them or they have to set frequency ?
Can you tell me exactly what is the problem 🤔
Actually, I have neighbour they always play loud fm and I am very tired now so I want to make device like fm jammer......
Plz help brother 🙏🙏🙏
This is not working
Without coil tuning deficult 🙏🏻 please use coil, between transistor's first lage (collector pin) for easily to build.
Bohot acha hay but ye component kaha milega🙄🙄
Electronics shop se kharid sakte hai 🙏🏻
@@amkp40technology acha bhai or ek baat batao
@@amkp40technology ye kitne dur tak signal milega 🙄
Pura video ko dekhiye 🙏🏻
