- How to build an FM transmitter circuit. A complete build from beginning to end including all parts, components and tools needed. FM radio station transmitter for home use. Have your friends and family hear you on the radio with this great affordable easy to build transmitter. If you don't have a printed circuit board and want to know how to make a fm transmitter on breadboard then this circuit can work for you. Even if you are just interested in amateur radio or HAM radio as it's known this is a great way to learn about transmitters.

If you want to build your own home FM radio station then this is the right circuit. With a good signal range and strength and clear audio. This is a great DIY FM transmitter for lovers of electronic kits and amateur radio. It might not be the best fm transmitter ever made but it is cheap and lots of fun. If you are studying electronics or just for fun you want to know how to make a fm transmitter then is a fun way to learn. One of the reasons to want to know how to make an fm transmitter is to try hearing your own voice on the radio and having friends and family at your house hear you as you present on radio. fm transmitter static is also something this transmitter can overcome because of it's substantially better range than a normal car FM transmitter. In fact apart from this being a mono transmitter it is probably the best car fm transmitter you can make. While it's not intended as professional wireless fm transmitter for car use it is certainly a more powerful and fun way to go. If you want to know how to test an fm transmitter the range is about the easiest test and this circuit will give you way more range than an MP3 transmitter for your car. If are not worried about the bluetooth aspect and want just wireless fm transmitter that is cheap and fun. Build fm transmitter with the basic components with no complicated circuit. Even though this is low power it's actually a long range fm transmitter when you extend the antenna. With the right antenna this circuit can reach a mile in open space like a farm or event grounds. The cool thing is that this is not big and actually a mini fm transmitter that can be used almost anywhere. The fm transmitter antenna is important as far as range goes. If you use the right fm transmitter antenna you can get more range out of this low power transmitter than a higher power fm transmitter. Some talk about the gold whole house fm transmitter antenna length which is actually simply the wavelength calculate from the FM frequency. This diy fm transmitter antenna is from a radio controlled toy but you can use a more sophisticated antenna.

I've build this 50 years ago. I am amazed it is still around :)
Yes this design has been around for ages. I built my first one back in the 1980's. Its such a great starter circuit that you can learn so much from. Not only do you get to learn basic electronics but you end up with a functional and totally fun transmitter that is just hours of pleasure to use. For the new radio presenters, as so many of my viewers are, this can be perfect for having their friends and family in their house listen to their first radio shows. I have built so many of these over the years that I don't know what I enjoy most, building it or playing with it. So much fun. I hope you decide to build another one again. Cheers :)
Seems simple enough :D
I just might build it for the fun of it :D
Yeah I love building these little FM circuits. They actually sound pretty good too. I like this circuit a lot because it doesn't have a microphone connected like so many FM circuits on CZcams. That makes it more of a radio bug than a transmitter. With this circuit you can plug in your little studio and have lots of fun. Enjoy. Cheers :)
It's a cool project. I'd give it an A for the cool factor and an F for assembly
I agree with A for the cool factor but I think an F for assembly is a bit harsh considering that there is no printed circuit board. I would say a good C+ to B considering what it's made from. Cheers :)
@@inspiresoundpro Someone did a great job with the design and initiative. Can't take anything away for that. It's the solder and wax that gets the F. Just my opinion though At least he built one. I just watched. Still a good video.
@@Slugg-O Agreed especially about the wax but I have seen much worse soldering on CZcams so I still give it at least a C. :)
There must be an error in the circuit diagram. The thick wire says both GND and -9V. There doesn't seem to be ay negative voltage, so I think GND is correct.
Yes I think the circuit was intending to show the negative voltage as a the earth or negative side and not minus 9V. I think this has more to do with that a 9V volt battery is used which would have a negative symbol but not actually mean a negative voltage because that would imply a 18V difference which this circuit probably cant handle. Thanks for pointing that out. Always helps to have extra eyes looking at it. Cheers. :)
I wouldn't advise building this as you need licences to build and test radio transmitting equipment. You'd also need to have a broadcast licence, especially if you are playing music.
That depends on the laws of your country. Many of these low power devices fall into similar categories as FM devices they can buy such as car FM transmitters and mobile device transmitters. Each country has their own laws regarding this so I always try advise people to know the laws of their country first. I don't give legal advice and this is not legal advice. That is why there is a disclaimer both in the video and the description.
What's about the range?
This transmitter as it is now can have a longer and shorter range depending on whether it is used indoors or outside. Inside a house it will probably reach about 30 meters but outside can probably reach about 100 meters. If the antenna is changed it can probably reach up to one mile outdoors. I will have another video soon showing how to change the antenna to make this transmitter long range.
@@inspiresoundpro With higher wattage? How bout 15 watt?
This transmitter is a very low power transmitter of probably only 30 to 100 mw. A higher power transmitter with 1 Watt or more will have a much longer range but it still depends on the antenna height and type of antenna. Often the antenna height will make way more difference to the signal range than the signal power. Often the signal power only helps to fill in the signal area or footprint but the antenna height can make a huge difference. For example a 1 Watt transmitter at 20 Meters high will have a much much longer range than a 20 Watt transmitter at 1 Meter height. So although the power of the transmitter does have an impact on the range there are other things to keep in mind too.
You mentioned nothing about drift. With such a simple LC oscillator and non temperature compensated components, and no drift compensation like a phase-locked-loop, there will be both short term and long term drift. Last thing a beginner needs is having to re-tune the receiver (or transmitter) every so often and wonder what is wrong. So bottom line, not a great circuit.
Thank you for your comment. It really helps beginners to see this kind of information shared. You are right this circuit will drift and a PLL circuit is better. That said I completely disagree that this is not a great circuit. This circuit was not intended to be broadcast quality or anything close to it. This circuit is a cheap easy fun circuit to build that gives learners an Immediate experience with FM circuits. In fact one of the best ways to learn about drift is to experience it. This is a learning circuit and it's a great one at that. Thanks for sharing your thoughts. It's of great benefit to the viewers. Cheers.
