How To Make A Radio Transmitter With Only 2 Components - Great Idea You Haven't Seen Before 

More than half a century ago, when I was a child, I used to do these kinds of experiments and handicrafts. After that, I did a job related to electronics and radio equipment development, and now I am enjoying my old age by taking up amateur radio communication as a hobby. I watched this video nostalgically. I expect you to become a high level technician.

I'm so jealous to guys, who understand electronics. I understand how elements work separately, but I cannot understand at all, how, and WHY it works in combination. It's total magic for me.

Микро сборки лучше паять на тепло отводе,больше шансов что останутся целыми,и паяльник желательно от 10до 15 ватт,и можно даже заземлить. В 70е микро сборок у нас не было,были радио лампы и были транзисторы. Однако в эфир мы выходили 😂😂радио хулиганы были мы. Увлечение переросло в профессию,14 лет отработал на ремонте радио теле аппаратуры, сейчас мне 65,но все равно продолжаю ремонтировать свою домашнюю радио и теле аппаратуру. Привычка понимашь 😂😂😂.

Pretty neat. Haven't made a radio transmitter since the 1970's.

Muito show mesmo... parabéns!!

Делал несколько подобных на разные частоты, правда антеннами побольше и с настройкой в резонанс. Дальность 500 м. С усилителем мощности на КТ 646 до двух км.

I didn't think it was possible wow thank you.

It is fun to put parts together, what is even more fun to understand the theory behind it and then design your own things.

Circuito inovador, muito bom parabéns. Guaxupe MG. Brasil .

Mechanical stuff, I can understand quite easily, but electronic gizmos facinate me. The awareness of the function and applications of each component seems to elude me.

Yup, that is a very simple transmitter. the crystal oscillator is actually a complete package in itself. All it needs is a power supply, an antenna, a telegraph key, now you have a low power radio transmitter. You can omit the resistor and your on the air, but you need a low pass filter on the antenna to avoid unwanted interference to other frequencies. ;-D

Awesome, I've also seen something similar done with just two pieces of wire!

Parabéns muito bom

Sorprende por su sencillez. 👍

the crystal oscillator is pretty much a transmitter in itself,i have tried this with a big salt crystal,it does oscillate as you can make a buzzer if you attach it to a membrane,but i haven't tried hooking an mp3 player up to it.

that was my dream as a child and it always was so simple??! :-) fantastic video!

Elleriniz dert görmesin emeğinize sağlık gerçekten güzel projeleriniz var.

Amazing! Complete frequency stability, clear full range fidelity, voices and music come through as if it were recorded in 4K and the stereo separation and signal to noise ratios are the best I have ever heard.

zafer kardeşim,sen nasıl bir ustasın ya, hayranlıkla izliyorum,ellerine sağlık

You are genious person, i have seen your this photo in a lot of electronic circuit blogs, Respect you. keep the good work up !

Muito legal!

The Crystal Oscillator is the Magical bit. It has a natural oscillation frequency that vibrates with an applied voltage. Vary the voltage and that natural frequency also changes. Hence FM modulation. The rest is just - simple electronics - adding a signal wave to the carrier wave and sending it off through the e.m. field.

Creative video, thanks :)

Devam edin hocam takipteyiz! Çok başarılı videolarınız var🇹🇷

This is one of the things that make amplitude modulation awesome.

Evt abi sayende gormediklerimizi senin sayende goruyoz Teşekkürler

Awesome video, thanks!

Very cool, Man! Russia is watching!😁👍👍👍👍👍

Sensacional, som bem limpinho.

Parabéns pelas postagens sempre inovadoras e didáticas.

Sí, solo envía largas distancias, pero su onda no cambia y puedes ampliarla con rf

Zafer abi bi canli yayin yap çokdandir yamiyosun ♡

Güzel ve değişik bir çalışma. Sadece cristal frekansı ile bile oluyormuş meğer. Bunu transistörle güçlendirip sabit frekansta etkili bir vericiye dönüştürmek mümkündür diye düşünüyorum. Eline sağlık 👍👍

Muito bem. Parabéns. Impressionante!

Just awesome!

If I am not wrong brown, red, brown is a 120 Ohm resistor not 100 Ohm that would be brown black brown. Besides its is not a crystal. It is an oscillator despite of what Chinese marketplaces that sell that describe as crystals, or translate as crystal. Crystals have 2 pints this have 4 pins and an VCC input. It has a crystal inside but has semiconductors too.

Interesting but what is the maxium range you can get with this set up? So far I see a range of about 4 inches. I keep thinking about the episode of Gilligan's Island where the skipper had to be hypnotised to try to remember how to convert their radio reciever into a radio transmitter, to finally get them off of the island. Could we save Gilligan with two components?

OMG this is amazing!

Parabéns, seria bom um projeto simples desses para transmitir e receber telegrafia em paralelo com um celular com app de CW para casos de emergência com 500mw ou 1w.

Amazing. That’s the way to go!.

A short Wave radio emitter, very awsome!

I love this music 🏃‍♀

Cristal oscillators oscillates at a certain frequency based on physical dimension. These oscillators are mostly used to feed a digital processor to get clock input. The oscillator creates a sinus like signal and added with the audio signal that results in an AM type of signal. The antenna coil generates EM fields when current continually changes in the antenna. This EM waves is then picked bij the radio …

Hocam bunun menzil hesaplamasını nasıl yapabiliriz. Yani 10hz radio frekansının yayılma yarıçapını nasıl bilebiliriz

The world's best teacher

Måste testas! Have to try this!

Try connecting a 15 meter long wire antenna which is resonant to 10 MHz I’m sure the range will be far better.

Guzel çalisma eline saglik mesafe ne kadar

That was impressive 👍🏻

MUITO MUITO LEGAL

Это классно!

I'd sure like to see this on a spectrum analyzer. That's a square wave, so it should be coming in loud and clear at 30, 50, 70, 90, 110... MHz. Interesting nonetheless, getting a lot of FM deviation.

Eline koluna sağlık 😊👍

Good circuit! You use capacitive microphone to modulate the 10 MHz xtal oscillator. AM modulation.

Cute project for little kids, but you really need a "low-pass" filter in the circuit to keep from interfering with other radio reception nearby, with a lot of useless "white noise". However, I calculate this only has a range of 12 inches at best, on a perfect day. - I've only been an "Extra Class" HAM since 1962.

Muy buen video, me gustaría saber cómo cambiar la frecuencia y si se podía hacer con una bobina variable, saludos y felicitaciones

Ha ha , the good old AM / SW communication :)

complimenti, bel video istruttivo👍

That is amazing and impressive. When I saw the title of this clip I immediately thought of the 1972 plane crash in the Andes mountains in Chile/Argentinia. The 16 survivors, all young men, ate the dead passengers' frozen bodies to stay alive for two months. One of the survivors had some experience with electronics and he tried to make the damaged plane's radio work as a transmitter, but could only receive public broadcasts from radio stations in Chile. While the boys would not have had a soldering iron, let alone solder and a power source, who knows what a very competent radio technician might have come up with, using components from the smashed on board radio. I suppose one problem with your simple example is transmission range. What kind of range are we looking at here, with the 9V battery?

Excellent circuit. But can you please indicate the AWG/SWG of Enamelled copper wire you used, because it could be important? Thanks. 🤔

Excellent job brother

Congratulations

La primera pieza que suelda dice ser una resistencia de 100 ohm pero no lo es. El segundo color es rojo. Entonces es 120 ohm.

Güzel bir çalışma ölmüş zafer abi tebrikler 👍✌️

Muy bien, que distancia tendrá de alcancé?

Foarte interesant

What is the part number of the crystal oscillator ? How high is the power output ? What range do you get with the antenna shown ? What licence conditions apply to operating such a transmitter in your country ? How much current does it draw ? How long does the battery last ? Cute project 🙂

Hello 🙂 On the photo that shows this as a photographic representation of what the video is about. But it shows on the photo a microphone and NOT a audio input. Have you a video of a transmitter something like this, that uses a MICROPHONE ??? Also what sort of distance dose that sort of distance can it cover ? Bye from John in England.

Genius!

Helal dostum. Eline sağlık

FCC has entered the chat.

INTERESANTÍSIMO vídeo y/o proyecto...¿Dónde extraeríamos de reciclaje ése cristal de 10Hz?...¿Ha de ser necesariamente de 10Hz?...¿No vale otro?,un nuevo suscriptor a tu Canal,pues me interesa éste tema,Like y Salud/os por áhi...

I found a new favorite channel. Totally kool

Gave this a try. Stupid simple to get it to work but really really low power. I had to touch the two antennas to hear the audio. I have an old PC power supply transformer around here somwhere. I am going to see if I can hook that up and boost the signal somehow.

QUAL O ALCANCE MÁXIMO

Time to talk to aliens

Awesome! Congratulations!

I wonder what kind of range he is getting with that with a quarter wavelength vertical would really help

😳😱😳😱😳😱😱😳😱😳😱😳 vivendo e aprendendo tooop

Qual o alcance deste circuito montado? achei muito legal. parabéns!

Bro! This is absolutely amazing! Can you do a video for a receiver that operates on the same frequency?

If you do even the minimal component salvaging, you can acquire quite a few crystals, especially pre smd, but even then only 2 pins.

Isso aí Magaibe 😁👍

EXCELENTE

Good job. How can you do a bigger one for a small area please?

Mukemmel bir calisma harikasin

great job

Very beautiful video i like it.

TEBRİKLER۔ MÜKEMMEL !

Buenísimo 😀😀😀

Ellerine saglik abicim 🇹🇷

Nice video but a little of explanation would make it better.

Sen bir Cevhersin Allah senden razı olsun Maşallah 🧿👏👏👏

Great :)

Make one using 12v from your car battery and use it to transmit your phone or pod to your radio. I use a similar but with bluetooth transmitted to my radio from my phone. Works great and I can change the input channel. Good ideas.

Aslında devre elemanlarının nasıl çalıştığı, içerisinde ne gibi bileşenler vs olduğu ile ilgili videolar yapsanız tutar gibi :)

Definitely a massive 👍's up 👉🇬🇧👈👉💎👈

You should be here before 30-40 years my dear because it’s too late but still I do really admire and respect your valuable creations.

Muy bueno..que alcance tiene?
