Build A Long Range FM Transmitter (Homebrew Radio Station)

Do i need the 4nf condensator

That so awesome

ایا میکروفون بیسیم همین هست؟

Hi I tried and test your circuit the same value, the same components, it works but i its only short range. I think 15meter only.

200miles = long range
20meters = not long range

imagine making a homebrew receiver

RadioShack doesn’t exist anymore.

So I got a broken Sony Xperia Z1 5 years ago (it has a dead battery). I left it in my house until in 2024, while I was reading the website talking about "phones with FM transmitter", I was surprised to see that the Z1's the one in the list. A few months later, one of my friend gave me another broken Z1 with broken touchscreen. I swapped the parts and I got one working. Setting it up was pretty simple, I need to root the phone, install Spirit Transmit app, plug in headphones (or whatever), play a song in the Z1 and voila, I got myself a radio transmitter at home. There is one downside however, the range is not that great (much shorter than the one in the video) and I have to put the radio closer than around 3 meters to receive the signal.

lemme head down to radioshack right quick

you know its old when radio shack was still around:p

Back then when I watch this I'm still in elementary school now I'm in college my major subject is about wireless telecom re watching lol it's Been over 7-10years

The only problem I now have is "my local Radio Shack store" doesn't appear to exist anymore..

Awesome video, Let's see more!

This so-called "toy" are illegal to use. It may disturb commercial transmission and more...

Whats is the gauge

Use leaded solder ,lead free is useless.

Damn

How to increase the sensitivity of the mic tho?

For what in the hell is the mic for?? Somebody please explain

You forgot one step in tuning it. Please turn it off and check if you are not jamming some licensed band used by some broadcaster or carrier. Still you need a license to run this and make sure you are not interrupting something else.

Just a piece of advice, depending on where you live: don't get arrestet after building this.

Is it okay to use BC 547 transistor

I made a fox hole radio transmitter over fm waves and i only knew how to build it cause a book in my elemetsry schools library explained how toae a fox hole rasio transmitter like they used in ww1,ww2 and Vietnam. I did it kne sat morning getting electronics from my schools store thst sells electronics and other stuff for kids to buy for thier projects at a discounted price compresd to box stores and i was 11 and my dad was impressed cause he was in the airforce and havnt seen snyone make a fox hole radio in a long time and he said he couldn't believe that his 11-year-old son would be the last person he saw make an FM radio transmitter like a foxhole one at 11 years old all by myself too My daughters looked terrible because I soldered the wires instead of just crimping so it'll be more permanent but it worked

Man thats so cool

So I made one of these. Except for the circuit was Stronger, because I wanted a higher wattage.(1.5KW) I wanted the signal to reach further.

I don't know it's legal to make an FM transmitter. I had mine running for about six months. Until I was forced to shut it down. Some unhappy Suit dudes claiming to be from the FCC. Had a warrant and confessated my transmitter.
Now I have to pay off an insane fine, I wasn't even harming anything. I was just propagating an electromagnetic wave.
Apparently you need a License to own and operate a transmitter. At least in the USA.
My country has turned into such a dystopia. I don't see a reason why they need to govern Electromagnetic waves. It's light at the simplest.

Even GMRs which some walkie-talkies have built into them. You still mean the license transmit on certain channels. I'm honestly to the point to where I want the FCC. Defunded. I don't even see a point for that branch of the government.

If no 0.1uf ceramic capacitor will it still work using a electrolytic capacitor 1uf. ?

FBI FBI !!!! Dug dug dug

Great job, amazing experience , you reminding me when i was young but with less budget :)))

Thanks for the idea. I can now use my wireless mic. 😁

How exactly does this work? I see a common emitter amplifier that is connected to the microphone to me that makes sense. I assume the other transistor is doing the modulation but I can't seem to determine how.

This is the way how a wireless ring is made

Could you link all of the components i have been trying to find the components for hours and i cant find it

THIS MAN SAID "HEAD OVER TO RADIO SHACK"?! 😂😂😂 NOW THAT’S PRETTY FUNNY

Nice man my signature in middle school was the Nyan Cat 10 hour loop 😂

Rangd and frequency ??

Sehr gut,in🇩🇪🙄🙄🙄😂😂😂🤐💖verboten!😂😂😂

Can some one explain how it works?

I build the similar device as a kid almost at the same age when you did this, in the early 2000's...nice to see someone with the same interest.

I remember seeing a channel (an English guy) making these on a 2p copper coin.. using the coin as ground.. he also made one like this for the top of a 9v battery.. i thought this was his channel.. this is a cool little project 😊

Loose the background muzak dude.

They sold this in a magazine from I think a guy in NY as a kit for 40 dollars.

I remember the 5-60 pf capacitor was a key part and Radio Shack immediately stopped selling that part once they saw the people coming in for the parts

And we wonder why RS went out of business

Like someone going in to Porche and saying I want a 911 and they immediately stop selling them

Idiots were running RS

Carcqut daygram please 🎉

OH MY FUCKING GOD I HAD AN ANEURYSM TRYING TO UNDERSTAND THE FUCKING CIRCUIT DIAGRAM YOU GOTTA REMAKE IT

How much long range it works

Interesting and I use it sometimes for fun. But I starting from this principle I would like to create a project, which is to create interference to my home hifi (I have to take a whim off) and then if for example I put on a CD or trivially the radio I would like to be able to change music or what I want at a distance (5\10 km). Who can help me out? ( URGENTLY ) Arduino. Teensy. Thank you very much. :)

Does it plug into the laptop audio out?

I cant find the frequency what do i do?

Did anyone try this???
