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.
wow thats cool, If i was you i would write a simplified book on how to make your own different types of AM and FM transmitter and recievers or open a youtube channel for tutorials . Anyway I wish you good luck in your life

61 here and was building radios/transmitters/simple metal detectors from 1975 to 1990, I used to get the components from broken TV/Radios devices.
Hola
If thats true why are u not calling out the bs of this awful video
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.
Don’t feel bad. I’m an extra class ham radio operator and I barely know enough to keep from smoking my radios…well…most of the time.
As an electrical engineer i want to say that learning electronics is very simple if you want to learn it.
@@cuf_ well, from the very beginning they starting to tell that electricity flows from positive to negative, but voltage flows in opposite direction, they talk about weak electricity on transistor base and strong electricity on collector, and also where comes resistance and power? And no practical examples at all.
Basically the silver box generates a constant 10mhz signal and the way that radio works is it sees that 10mhz signal and when that signal becomes louder or quieter itll generate sound and basically the headphone jack is sending signals to that box too for example 1000hz so that signal becomes louder in the same pattern as 1000hz thus that radio can see this change is loudness and decode it
@@romanyarygin1674 looks like the people that told you this are bad teachers. They make it simple for them but hard for you. A transistor is a switch. And electricity goes from plus to minus but ELECTRONS go the opposite. The fact that electrons go the opposite direction does not matter unless you are making a vacumm yube CRT aka the electron gun.
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.

Pretty neat. Haven't made a radio transmitter since the 1970's.
It is fun to put parts together, what is even more fun to understand the theory behind it and then design your own things.
Muito show mesmo... parabéns!!
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.

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
no need for an LPF at such microscopic power levels with a short antenna.
@@jemussi7842 Yup, anyway it’s not going to be use for serious QRP work.👌🏻😀
This can be fake. Electroboom needs to rectify this.
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
Also it's way more than two components. Click bait.
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.
Do you know this transmitter how many meters or km works?
@@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. ;)

This is one of the things that make amplitude modulation awesome.
So it's an AM radio transmission ???
@@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.

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.

FCC has entered the chat.
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 🤣🤣
@@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.
Ok, you’re right about the antenna, it’s not a coil, but the antenna is responsible for emitting EM wave due to alternating charge particles in the wire.
This project you call garbage makes a lot of young people to study electronics because it just works and it’s fun.
But you must live happy a happy life, if according to your reaction.
do you know if instead of using a headphone jack if you could use a 1/4 quarter jack socket for example for instruments or a microphone to plug into?
@@rachelmcg7186 Stereo 3.5mm and stereo 1/4" are exactly the same wiring in just a different diameter package. You can either use adapters to make the connection or you can use a 1/4" instead of the 3.5mm. Me, I'd roll with the 3.5mm because I use that type of cabling the most, and adapt to 1/4" as needed.
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?
The fact it actually happened sucks, but the movie they made of it, really sucks.
@@darrylkinslow5613 Yes, the books written by the survivors were much better. Nando Parrado's book "Miracle in the Andes" in particular.
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.
What you would do is use a ready made off-the-shelf personal locator beacon which communicates with overhead satellites which are all flying past listening on the agreed frequency your locator beacon is operating on.
@@deang5622 How many satellites were "all flying past" in 1972? And where would you have purchased a "personal locator beacon" in 1972?
@@SuperLittleTyke The answer is possibly none. And I knew that at the time I posted my response. Because they weren't launched until a few years later.
But I wasn't talking specifically about that airline crash ..I made the point that an RF transmitter on some random frequency would have been picked up by emergency rescue!
So the idea of making an RF transmitter was completely stupid and not possible. And even if it could have been made, it would have been entirely ineffective.
The key point being, your post was a complete load of bollocks. And you want a 100% factual answer under those circumstances? Dream on mate
Dream on.

A short Wave radio emitter, very awsome!
That sounds like pretty good fidelity, to me !
But being 10 Mhz, can you move the Frequency to the 30 meter Amateur Radio Band, and send Morse Code with it, perhaps by using the Code Key as a simple switch, and turning power off and on ?
🤔....?
Try connecting a 15 meter long wire antenna which is resonant to 10 MHz I’m sure the range will be far better.
Next we interfere with the atomic clock signal of WWV in Ft Collins, Colorado?
@@skeggjoldgunnr3167yea let’s build a complete fm station next time, ofc completely diy😂

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.
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.

Good circuit! You use capacitive microphone to modulate the 10 MHz xtal oscillator. AM modulation.
In 1972 I used to do them the hard way, with diodes, coils, variable capacitor and a transistor.

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.
Creative video, thanks :)
Better will be on the air tonight :)
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?
Sir, if you find the answer, please post it here. I'm trying to save Gilligan too..
X2
If they built a working VOR station, sending SOS in morse code as the station identifier, I don't think it would save them.
@@douggale5962 Not many people know morse code.
There is no saving Gilligan. Mary Anne and Ginger? Now that's another story.
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.
Здесь используется амплитудная модуляция.
Here amplitude modulation is used.
The antenna coil acts a bit as a lowpass filter
Harmonics LIKE FUCK. I used to make small CW transmitters for tracking or whatever and they would splatter like hell at all the predictable harmonics. 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.
Just awesome!

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.

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.
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 🙂

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 ?

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.

This video should be titled “how to piss off the local hams, and the FCC with this one simple trick!”
For real though, nice video. Super simple, to the point. Just be carful with it, as this is really close to a frequency that you need a license to operate in, and you may also be interfering with time stations. This radio might be very low power, but I have seen someone make a contact in Hawaii from colorado with less than 5 watts on HF, so it is still possible to mess with things.
