You can replace the 47pf with a 10-350 pf variable, so that you can choose the frequency you broadcast on. Also use an NPN transistor so that you can power it with 25-40 vdc. This increases the range alot. (transistors you can use: bc547, bc337, bc 237, 2n2222, ac127, 2n3904 or literally any NPN :D (this does 300m at best)
also if you are feeling experimental replace the transistor with a bu208a high voltage NPN. You can feed this transistor with voltages exceeding 400v, replace the resistors and capacitors with high volt. ones and there you go, you now got a range of 10 km (6.2 miles) very fun and very illegal :D Improvements: 0.1 uF cap ant the input to filter out noise. for a range of 1km you will need a 50m antenna or a 20m vertical one. All of the components can be desoldered from an old cassette player or radio. This transmitter is actually a great design but fails on the sound quality because of the 47pf cap.(like I said replace it with a variable tuning capacitor (can be found in an old am/fm radio) and it should work fine). Tap the antenna on 2.5 turns of the coil for greater stability.
Ages ago I did similar projects. I remember instead one of capacitors was a variable capacitor and there was second coil (3 turns) placed inside 5 turns coil. That changes were giving me opportunity to tune into other different frequencies.
I have built so many of these simple fm transmitters , the maximum range I got was 400 meters (weak signal) .the transmitter was perfectly tuned to antenna of 20 cm length .
This specific transistor has the collector in the middle and the base on it's right at 2:54. It's not E B C, it's E C B as per the datasheet of 2SC2655 and the following construction of the circuit in the video.
@ gillani data Do you think this schematic can work with any FM receiver? For example, with the F-908 (it's not a toy but you can't say it's rubbish either). That tx that was included, once it was powered up it charred within 2 seconds. Sometimes bad components happen.
dear 104 is not generating frequency 104 is used to control just battery effect on the transmitter whoever 47 and inductor coil is is generating frequency in this project this project is so simple that i can measure perfect frequency
Thanks for everything.....its amazing .... You really helped me a lot....I liked your video and also subscribed it...... Even downloaded it.... Thanks.....
You would freak out radio listeners if you broadcast this message continuously, "Greeting earthlings. We Martians are arriving on earth in 24 hours...."
2km lol that's impossible mate....this can cover 30 meters with antenna at it's best..you need a high power transistor to cover this range like 2n2219a
Oh ya he did a good job with what he had. But fml, that's the worst tip I'VE personally ever seen lol... I thought mine needed replacing ASAP. Holy fak.
You're right, 102 is not read directly in pf, it is coded. It must be converted to normal. So 1 is 1, 0 is zero, 2 is two zero, equal to 1000. 1000 pf or .001 microfarad.
I want this to broadcast music from my bedroom to the kitchen so I don't need a mic. How can I connected to a audio device ? Do I need a headphone jack or something ?
And ...can you help me in one thing...please... I have to make 2 of this.... So it must be of different frequency.... So how can I change the frequency...?...

(That's really important!!!) for a good reach of course! Regards!
And even after connecting 1/4 wavelength long antenna u still need a matching network to match impedance of source(transmitter) and load(antenna) if they r not same
maybe try 87.7 mhz because less stations in that tuning and that some micro fm transmitters for cd players us that tuning. . Maybe put another turn on coil to lower the frequency a bit and use an antenna just a few inches long and resistor if needed so as just enough power is used for the needed range. It will help avoid interfering other channels and all is well. Put circuit in metal shield box with antenna wire comming out from it. Or just buy a chesp fm transmitter at a dollar store, no skills needed.
I made it with variable capacity capacitor, some more precised resisrors and 2 potenciometers, i rebuildet it so it has power regulating on fm power booster, it makes 34w fm signal max, wide range from 48.2 to 116.9 mhz, i tested it on rtl2832u dvbt tuber on sd sharp.
That capacitor marked "102" is not 102pF, it is *1000pF.* 1=first digit 0=second digit 2=multiplier according to table: "0"= X 1 "1"= X 10 "2"= X 100 "3"= X1000 etc. So the "102" marking means 10 multiplied by 100 = 1000pF, or 1nF. www.petervis.com/electronics/Ceramic_Disc_Capacitor_Values/Ceramic_Disc_Capacitor_Values.html
not clear what is the purpose of this transmittor what is transmitted? how to transmit what we want to transmit can we have another DC (with two wires +ve and -ve) that sends input signal and this transmittor trasnmits it?
I want aske you when you don`t have microphone you didn`t replace that microphone to the jac(heard of ecouter) of audio in order to put music like music for telephone !is it impossible/possible
There are a number of crippling problems with this simple transmitter, the main one being drift and load instability, as the antenna moves around it changes the load on the oscillator causing it to drift off frequency, useless.

That capacitor marked "102" is not 102pF, it is *1000pF.*
1=first digit
0=second digit
2=multiplier according to table:
"0"= X 1
"1"= X 10
"2"= X 100
"3"= X1000
etc.
So the "102" marking means 10 multiplied by 100 = 1000pF, or 1nF.

dear u can use mp3 with it but u will have to use fm receiver for tuning it
There are a number of crippling problems with this simple transmitter, the main one being drift and load instability, as the antenna moves around it changes the load on the oscillator causing it to drift off frequency, useless. Range depends on a number of factors, but rf power output is in the micro-watts being very weak, limiting range to about 50~100M on the average fm radio.
I made a few of these. Every word that you have written - is the truth.
Thanx dear
the circuit is to close of receiver. Good equipment. It contains 2 bands of sw.
it is due to show the receiver and transmitter
It works but a simple calculation of exact out put power shows that 10 meter will be the range finally.
use long antenna dear then its range will be increase
