Please explain the working of this circuit Please make a video on Circuit diagram of 433 mhz receiver This 433 mhz transmitter circuit is same as the Circuit of the 433 mhz transmitter and receiver module's used for the RC toys to control the dc motor of the RC car
hii.. i made this with 100MHz xtal. it can received by fm radio, but the audio is very low, even in full volume (input source & radio receiver). i try to use mini amplifier as input in this circuit, but the audio quality is terrible. how to fix this? to improve the audio quality
You can't pull the quarz frequency enough to get +-75kHz frequency deviation for wideband FM (87-108MHz). Its only good for Narrow FM applications (NFM=+-2.5kHz) on LPD/SRD/HAM bands
@@blechhammerer4008 i tried another schematic, and worked. Audio quality is better. I use 2 pieces 100MHz xtal in parallel to improve audio qualily. Now i have stable FM transmitter.
@@blechhammerer4008 i use this schematic czcams.com/video/FauFCfy4jeM/video.html I use this scheme, with the adjustment of 2 pieces 100 MHz crystals installed in parallel. and by adding 2 stages of RF amplifier to extend the range.
You can't pull the quarz frequency enough to get +-75kHz frequency deviation for wideband FM (87-108MHz). Its only good for Narrow FM applications (NFM=+-2.5kHz). 27MHz on CB-Band should work, you will hear the sound loud enough.
Not true at all. An end fed full wave antenna is a very high impedance. If you want a better antenna use a half wave at the feed point and another have wave from ground.
I know this comment is kinda old but i'm having trouble understandig the vales of the components, you say that r1 should be 47 kOhms, so what is the value for r2 and c3?
@@francogaretto2479 Hello! I am from Russia and you asked me a question (I wonder what country you are from? If you want, tell me here). There are two versions of this transmitter. Artyom (the author of this video) showed it to us. The second version is the Chinese Module= fs1000a. I think the Chinese module is better. Resistor R1 is assigned with a power source supply: at = 3 V, as = 22÷27 Kohm, at = 6 V, as = 33÷39 Kohm, at 9÷12 V, as = 47÷ 56 Kohm. We make other components without changes.
TLDR: yes, replace the crystal with a 100MHz (or so) one explanation: his radio is a dual band FM transceiver so if it can receive his FM radio broadcast at 433MHz with such an oscillator, if you replace the crystal oscillator you'll be able to broadcast on a different frequency but with the FM modulation because of the circuit
@@evieanindyaputri610 you don't have to adjust anything, however you will have to adjust the r2 or c2 if the circuit won't oscillate. if you find yourself having a small range, try adjusting c1 and l1. also a good idea is to use a low pass filter on the antenna output so you don't send out harmonic waves outside of the FM band.
Very nice 👍
Hope to see it with a microphone input
thank you for all your clip!!! very very excellent... good lock
You are back! Nice to see you again on youtube. Английские субтиры и фоновая музыка украсят видео, и помогут зайти англоговорящей аудитории. ;)
Great Artem, what is the main difference between this transmiter on 433 and the FS 1000 a arduino modules on 433 mhz respecting power OUTPUT? CHEERS
Muito top nessa freqüência ai gostei 🙋👏👏👊
How do I do it with a simple on/off switch? What do I add instead of a microphone?
Is it uhf band(ham) transmission?
Why a 11,5cm Antenna and not 17,3cm?
Bi zamdn fm icin cok ugrssmistim ve vericiyo de uzaktan ac kapa yapmak istemiştim vericiye farkli bir frekasta konrol etmek cok istiyorum bu cok mu zor
Could you publish how the tester you use is made?
Nice video as usual
Where did you get this circuit schematics from?
what's the value of L1 inductor? 10uH or 10nH?
Wait to see another video with amplif stage
Harika devre olmuş
Peki orada gerilimi degistirincemi mesafe artar akimi artinca mi
Her iki durumda da frekans değişir mi

Si coloco un cristal de 1Mhz, funciona?...
Can you buit one stage rf amplifier?
Can this be adapted to 868mhz ?
I love it good 👍

would it also work with an 100 mhz or 27 mhz crystal?

Man....man..... You are e.t.... congratulations..... Nice ...nice....
Can I replace this crystal with L/C tuned on 433?
will not be stable enough
Can you make one that works in 2.4ghz or 5.8 GHz or upper?
Recommendation: Aliexpress is selling such ready modules. For this high frequency its hard to make own schematics/layouts.
@@blechhammerer4008 thanks for attention, do you have some link to recommend for me?
Bro, its real work?
Make the antenna 70cm in length and you will have a full wave output. It will go even further :)
Not true at all. An end fed full wave antenna is a very high impedance. If you want a better antenna use a half wave at the feed point and another have wave from ground.

Dear Artyom! You are not right. The resistor should have a value of 47 kOhm, and your circuit contains a resistor with a value of 4.7 kOhm.
