You are back! Nice to see you again on youtube. Английские субтиры и фоновая музыка украсят видео, и помогут зайти англоговорящей аудитории. ;)

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

@blechhammerer4008 21 күн бұрын

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

@BitsofSkin Жыл бұрын

Make the antenna 70cm in length and you will have a full wave output. It will go even further :)

@davidgilbert6 Жыл бұрын

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.

Recommendation: Aliexpress is selling such ready modules. For this high frequency its hard to make own schematics/layouts.

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.

@francogaretto2479 28 күн бұрын

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?

@gc4mv 28 күн бұрын

@@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.

i have 100MHz crystal, if i replace the crystal with my crystal, can it works as FM Transmitter ??

@maalos Жыл бұрын

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

@maalos Жыл бұрын

@@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.
