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
I just watched a koren zombie movie. The kid did this sending out a picture holding up a sign saying he was a survivor using a pair wired headphones..and an app he had on his phone implemented by his govt in case of an emergency
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.
@@rubis5153 Not very far. Signals decrease according to the inverse radius squared - and this signal is already pretty weak so... I don't expect much. ;)
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.

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.
@@nicolaraimundodiportella6937 It's a shortwave transmission, so it's not in the "AM band", but it is amplitude modulated. The information is in the amplitude of the signal at the carrier frequency.
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 …
Please don't publish nonsenses. Crystal oscillators do NOT produce sinus, and adding carrier + audio does NOT create AM signal. The "antenna coil" has open end, so it does not act as a coil at all. You know nothing about the radio electronics, similar to the author of the video. The circuit seems to work, but it is a garbage.
@@jankolar5612 I said sinus like signal, not exactly sinus, maybe you should read better instead of searching for other’s mistakes as a hobby to satisfy your ego.

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.

Don't be silly. In an emergency incident, you wouldn't cobble together a radio transmitter on some random frequency which emergency services didn't know you were transmitting on.

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.

The solution was a cap and coil BEFORE the antenna wire to reduce everything except a target harmonic. This way I could use say an old 27MHz CB crystal and have a useful output around 108 MHz, easy for my old handheld scanners of that era.
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 🙂

Awesome 👍... Next use an oscillator for 80+ mhz
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.
I made the exact same comment. Besides the box is a crystal oscillator not a crystal alone.
FANTASTIC!
Excellent circuit. But can you please indicate the AWG/SWG of Enamelled copper wire you used, because it could be important? Thanks. 🤔
Nice project

OMG this is amazing!

It was a dream from childhood, though i am now physicst, i am going to try
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.
If you haven't figured it out yet Jon, I'd be interested in building one and testing it. We can share results. Just ordered a pack of 10 Mhz (and several others) Oscillators, and a pack of different resistors. Believe I have the battery connectors, wire, and audio plugs. I'm actually thinking of using it between walls, and underground a few feet.
Very beautiful video i like it.
Muito legal!
La bateria, la resistencia, el cristal y el plug hacen cuatro componentes no dos.
Muy buen video, me gustaría saber cómo cambiar la frecuencia y si se podía hacer con una bobina variable, saludos y felicitaciones
EXCELENTE VIDEO SE HIZO ALGO PARECIDO ACÁ HACE UNOS AÑOS

Bagusss..👍👍👍
Thnk you for sharing this , go head
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...
does it also work when i replace the 10 Mhz Crystal Oscillator with a 100 mhz Crystal Oscillator?
probably, it'll just have a different frequence.
QUAL O ALCANCE MÁXIMO
15 cm del transmisor-receptor.
Eline koluna sağlık 😊👍
Teşekkürler kardeşim
Brother can you a circuit details for 500 metre walkie in simple circuit, liecence free in India band
Very good
