0:27 - The caption of "104 PF" is wrong. "104" indicates the significant figures of "1" and "0" followed by four more zeros. The unit is picofarads, so the capacitor has a value of 100,000 picofarads, more commonly referred to as "0.1 microfarad."
So, the capacitor value is shown wrong, because on these kinds of circuits, a common value should be from 10 to 100pf.
It will give 1km range after attaching 1km antenna.
I bet it won't be heard across the street.
😂😂😂
🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣
I agree. I have experience with this type of devices. ❤😅😅
That is not how it works, you will need additional RF amplifier in order to increase the range
bro.. can i put a AUX jack insted of mic in this circuit? will it work?
I believe that first capacitor is a 0.01 micro farad, not 104 pico farad if i understand my marking conventions correctly.
The correct value should be from 10 to 100pf for this use.
That is correct, the one I made several years ago had a variable cap 10pf to 25pf , also two transistors .@@DihelsonMendonca
Dear sir. You said, 14 gauge - 5 turns, but you didn't tell the diameter of coil. Please tell. And one thing for all your viewers, longer the antenna - higher the performance. Regards
The color coding on the resistors appeared to be 460 ohms (yellow, blue, brown) and 10 ohms (brown, black, black)
Ted_van_ loon you're absolutely correct. He didn't tune the coil by opening it and closing it to get the proper frequency on the radio.
Make a second video, this time add a dipole aerial (straight piece of wire) 0.833m long in one direction and another piece of wire 0.833m long connected to your ground in the opposite direction. Also don't touch the circuitry when you are testing it.
Question about the antenna you talk. Could you make a draw and send it by gmail?
thanks for video.it is nice
but is it truly FM? And what diameter is that coil? The one cap you say is 104 pf is not. it is a .1 microfarad capacitor. The other is correct at 4.7 pf. And I bet you can't be heard across the street. Silly project.
Interesting take care ! 73 de ve3hip from Welland Ontario Canada 🇨🇦
Some things this video is missing:
Proper circuit layout
Good soldering practices
A functional circuit
Basic hygiene
Soap & water
Unpaid Shills you tube expert ? Don’t suppose you have ever made anything ?
Yes
Thank my friend to share your idia..
bro what about antina because without antina 1 km no possible-
What..!?😲😲😲
It transmits at all frequencies..!
if I wanted to recieve a very different wave like ELF can I make a reciever like this
Does not work for me. Maybe because I'm using 3,3k ohms instead of 4,7k ohms, but that's unlikely.
Also in the video you are doing 6 turns, not 5.
Btw the reason he uses a 2655 transistor is because the maximum switching frequency of that transistor is 100Mhz, so he uses it to set the frequency.
He is probably using a 3,7V battery.
This very good. And I want to test it for educational purpose. The main question is that I can't know the frequency of the carrier. Any one who knows plz tell me!
Trima kasih, sudah memberikan video tutorial pemancar radio FM.. Salam....
Jaraknya bner 1 km om?
@@ajengmemberihadiah5612 pake 12v amplifier, bisa aja kayaknya untuk km. cuman kalo pemerintah tau yaudah, tinggal lari aja wkwkwk.
Veri nice. Bravo
Great build but probably very illegal in some countries.
Good job, you can change your phone screen next.
Wow! Amazing video 😯👌👆🙏
No le creo porque no demuestra el alcance , lo tiene que acercar mucho al teléfono.
Only one slight problem, and that is that the coil needs to be tuned. the length of the wire also has a effect on the impedance.
You're absolutely correct Ted! He has to open and close the coil wire to get it tuned correctly instead of just tapping the microphone over and over. When you hear a shrill squeal on the radio. You then have the right radio frequency too.
второй резистор,там вроде третья полоса коричневая,значит 470 ом,а написано 4,7к?
Range no more than 10 feet. Lied about the range
Terimakasih telah berbagi ilmu, sangat bermanfaat.
And if we talk through the microphone, do we hear the sound on the radio?
1 km yea right thanks for showing everyone how not to build a transmitter.
gracias lo hise en mi casa y funciono aun que el microfo tiene saturacion al maximo
Can I use c1815 for the transister in this circuit?
Yes, its too NPN
Yes but it Will be very unstable
Nice info, thanks :)

Паяет картины объёмные,
пальцами тёмными неуёмными
пищат они пронзительно !
удивительно удивительно
Not 1km but 1cm!
Pode me mostrar qual foi a foto do circuito que usastes?por favor
it is possible to set the FM frequency with a digital circuit such as MCU
Jamais que isso da 1km no máximo 50 m
O segredo está na antena
50 m con suerte. Yo apostaría por 10 m
1km!! Non scherziamo per favore
Roland Eletrônica
5 metros si te creooooo con antenaaaa
What is the power in put?
Thanks
But are you sure the range ( distance) equall 1000 m
مداه لا يتعدى 20 م الى 50م حسب طبيعة التضاريس و الهوائي و نوع الترانزيستور
This one 10 to 15 meters only.
Good
Mielenkiintoinen Video mutta toivoisin myös kytkentäkaavion näihin projekteihin no ehkä sitten tulevaisuudessa.
What's the value of the coil in Henry?
Watch powerful FM radio transmitter circuit.its working

S9018 good ?
At 0:33 sec is that a copper wire??
Please reply sir 🌹
its insulated copper wire. just go to local electrical shop and ask for 14 gauge insulated wire and they will know.
@@tanmoysd2721 thanks😊
@@tanmoysd2721 what must be it's length?
Can I use other transister?
(because I don't have any 2sc2655
can I use this to block radio stations on my office? a working partner listens a horrible station and I want to block it
Yes
Hollywood role models using a silencer with gun!
this is how art bell got started in radio
ya, and starting with such a small transmitter, it wasn't Coast to Coast, it was Closet to Coat Rack
please make a 5.8ghz wifi transmitter tutorial
c2655 can't find it . it's hard to find what is the equivalent? thanks
Time weaset Use Your Earphones
thats why using Earphones
Earphones is our Antenna Fm Transmeters
EXCELENTE TUTORIAL ,FELICITACIONES ,ES EL MEJOR
Can you make video, mini fm receiver ?
And so his brain also freezed on TAPPING the MIC. Tap, tap, tap .... Tap, tap tap .... Tap, tap tap ... Tap, tap, tap ... Tap, tap, tap ... Little does he know that touching the circuit, will be changing the transmitting frequency as his hands will be changing the capacitance of the oscillating circuit. Tap, tap, tap ....
kkkkkkk capacitor 104 nao e 104 pico pf nao,,, quando temos um capacitor com tres numeros o terceiro e numeros de zeros por exemplo um capacitor de codigo 104 e (10+0000. que e 100000 pulando tres zeros da direita pra esquerda colocamos um ponto que (100.000) pra cada 1000pf e um nf , 1000pf= 1 nf.. 1000nf
capacitores de codigo 104 e 100 nf 100.000
E isso mesmo 👍
Can I use bc547 transistor
This absolutely will not transmit any distance at all. The rf output will be drifting and the signal will not be consistent
But worked
anyone can help me pls, if i would put antenna spiral on this project where is should be located?
Don't know :/
positive side of the coil
the positife off coli bro... wkwkwk
Baixa potência e falta de uma boa antena , reduz seu campo de irradiação, não basta ser um oscilador de frequência ajustável.
Does it really work with in 1 km range? And not resistance of buildings
Just oscilator
Impossível,ainda mais sem antena .
HOW TO SET THE FREQUENCY?
adjust the coil- add more or less turns or expand space between them
@@randomytpstation3261 if you're interested, you can also look at this channel ruclips.net/channel/UCR8WKNLqmQsvKmHt_CnEr5g
BOTH 4.7 RESISTOR AND 4.7 CAPACISTOR ?
that is not 104pf!!!!! Please remove the word "tech" from your channel name!!!! That is a .1uf. Please learn before you try to teach
James, if you hold down your 'alt' key, then type in '230', finally releasing the 'alt', you get 'µ' !
@@benmorris2901 He called it a 104pf capacitor. misleading. Common rookie mistake
104 = 10x10^4 pF = 100nF = 0.1uF (?)
Un receptor fm por favor asi de sencillo como el q hiciste saludos
Imposible mission.. How can transmit 1km. Without ant.
Remove your video thumbnail, with such config. it won't work properly even for 100 meters.
It's dead in 1 meter.....
Yeh jo 14 gage wire batate ho uss ka to coile banta hi nai hai aur iss ki freuency kia hogi
sir can i have aschematic diagram of this? asap
Ok come
Sir eh one meter tak v nahi chall reha .te 1km tak kida chale ga 😁😊😊😊😊
Está faltando uns ajustes nesse circuitos.
Mas valeu abraço!
Por favôr,especifique QUAIS ajustes.Obrigado.
Realmente, faltou mais componentes.
No basico, um eletrolitico de 200uf com um ceramico de 100nf em paralelo com a alimentação o mais proximo do positivo da bobinha ociladora.
Um trimer em paralelo com a bobina ociladora que deveria ter uma saida para a antena na segunda espira proximo ao positivo.
Um sistor de 3k9 entre base e negativo.
Um capacitor ceramico pra desacoplamento de 10 a 20 nf em paralelo com o resistor 4k7.
Um resistor de 2k7 no positivo pra alimentar o microfone de eletreto qu deve enviar seu sinal por um capacitor de 1uf pra base do transistor.
Um trimpote de 10k pra ajustar a entrada de áudio.
Nao creio que este circuito forneça alcance de 1000 metros sem outro circuito de amplificação de RF
😀valeu amigão !👍
@@sebastiao.5758 daria certo com o transistor bc547???
Please explain the science behind it
Faltou a antena. Ele não conseguiu sintonizar a frequência fundamental. Acredito que foi captado apenas alguns espúrios por estar próximo demais ao receptor.
Transistor 2655 max 40 MHz ?
Boa tarde Marcelo de Taubaté tenho interesse de montar um transmissor para mim
Can we use BC548 transistor
Yes
5v or 6v ?
Se equivoco en el titulo. Puso 1 kilometro y es 1 metro de distancia...
SI DA UN KILOMETRO DE POTENCIA
Excelente proyecto deseo construirlo y tenerlo en mi historia.
This isn't an 1 Km transmitter. Only 100 meters. We tested it out
Is this video correct? Have u tried?
O BF 494 eu tenho um transmissor de FM muito bom mesmo da 1vatts de potência com uma antena 1/4 de onda vai a 10 KM
COM TODO RESPEITO AMIGO,MAS Como conseguiu este alcance?Mostra aquí,para nós fâs curiosíssimos.
Holâ! Eu nesesita esquema, please! Boa noite amigo!
Pega 1km mesmo, verdade???
Oi tem como vc passar o esquema do seu?
Top
ese transmisor , si llega a 10 metros , es mucho .
Can I use bc547
Hato yig'ildi kontir kaninsatir bilan paraleb bo'lishi kerak
Схемалани йигиши биласизми??
would it work if I use bc548
It should but the sound would becone more static
amazing i made it as he says and for about 100000000000000000000 miles
Como cambiamos la frecuencia? Más bobina
Ciao, mi serve un progetto di un semplice trasmettitore e ricevitore. Per esempio accendere e spegnere una luce a distanza!
So where is the schematic and explanation. With no antenna no range and not even a demo of resl sound getting to a recievet.
Keya aap dj ki masin band karne ka dibaij banasate hai
can i change 2655TR to A966 or C2383 ????
Einen UKW-Sender auf diese Weise herzustellen ist geradezu abenteuerlich. Die Frequenz ist total instabil und der Betrieb damit ist verboten ! Es können damit auch andere Funkdienste gestört werden !
Não comprovou sua funcionalidade.
No function.
License most need
Muito legal parabéns amigo
What can I do for increase the range
Pick another circuit, this one is garbage
Tell me what resistor i use for 9 volt battery
Try a 10K instead of the 4.7K
It won't go more than 100 meter
