fm transmitter DIY 5km FM Transmitter Circuit Diagram

[@MohammadOaes-f3m]

I just can't count how many radio-related receiver/transmitter videos this guy has made. Shine you amazing bastard

[@666Bern666]

Always find these channels amusing. As an experienced engineer this is terrible. Unlike some others out there this will actually work, range a few hundred feet max maybe not 5km! Clearly no idea what they are doing though. At these frequencies it should be a double sided board with one side a ground plane and you keep the component lead lengths to a minimum. The output device in the diagram in the links looks reasonable, the one in the video does not!

[@instructoruldemeditatie2367]

Why don't you make a video on how to do it if you still have time to see what others are doing?

[@czekuch]

The transmitter range of 5 km is unrealistic, it's nonsense.

[@alexakhmetov4616]

​​@@czekuchit's realistic if you have a transmitter that's capable of delivering at least 7-8 watts of power into the antenna(such transmitters are pretty popular today) and a good tuned antenna placed as high as possible

[@czekuch]

What is the output transistor? Can it generate 5-8 watts of power ??? The antenna is not needed if there is nothing to send. The project allows for communication up to 150 m. This is my opinion, yours may be different.@@alexakhmetov4616

[@Bartok_J]

Agree! Very poor technique: components waving above the board? Scarcely OK for audio, let alone VHF. :-(

[@humorhut1]

A.O.A! Plz snd the circuit diagram of the FM transmitter

[@mondude9754]

Anyone wanting to build this HE MISSED A CRUCIAL STEP IN THE ASSEMBLY PROCESS. You see he never included a resistor to give a + bias to the base leg to first stage oscillator transistor. It will not do anything without that resistor in which is what happened when I built it. I finally noticed at 3:39 you can see the extra resistor he forgot to add in the first place. It looks like a 2.2kohm and is on the immediate left side of the variable capacitor. Mine still only transmits a few feet, though I didn’t use the same transistors he used and mine are far from being rated for the frequencies

[@inventorkr1]

Good note: Yes, everything you said is true

[@josue19731000]

[@dragan3290]

I like the frequency counter!

[@skunkybillmarleey5652]

if you put a 7 element antenna on it and put it outside, it's even bigger. nice video thanks👍🤩✌

[@inventorkr1]

Yes, using a longer antenna increases the range of the FM transmitter

[@HendroSusenoHadiSudibyo]

i'd like to know abou that frequency counter

[@mikepaul2831]

This transmitter works properly within perimeter of the table it is situated on. One stage amplifier on 9018 and 5 km it is a very nice tale.

Thanks for video, its great🙂

[@inventorkr1]

Your interaction with the video encourages me to provide the best. Thank you. Stay tuned for new unique electronic projects

[@johnman1286]

I don't see anything that would provide the 75us pre-emphasis for the audio. The output transistor which looks like it came from a junk CB radio, has the collector (center lead) grounded instead of the emitter. It would not have any gain.

[@nicoschadjidemetriou4373]

Thanks my friend. If your transistor gives power up to 5 km it must need heat sink for sure?

[@inventorkr1]

Yes, of course

hola saludos desde planeta rica colombia... como es la formula para calcular las antenas gracias compadre

[@Tonicutis]

Para calcular un dipolo simplemente divides 150 entre la frecuencia, por ejemplo para 100 mhz sería 150/100 = 1.5 m o 150 cm eso sería media onda, luego cortas varillas de 75 cm cada una (75 x 2 = 150) y las pones separadas unos 3 cm en línea recta y a una va el vivo y a la otra la masa o tierra. Tendrás un bonito dipolo cuya eficiencia es sorprendente.

How NOT to build a circuit for VHF. Leads should be as short as possible, components close to the board: not waving around almost a centimetre above it. All that extra inductance and capacitance is asking for failure. Please DON'T regard this video as an example of "good construction technique" - it's the exact opposite. :-(
