How to make an FM transmitter with an output power of 500 mW

[@techtinkerin]

The wire on the coils doesn't look like 0.2 mm and 0.5, looks more like 0.5 and 1 mm.

[@hobbyrob313]

i think the 2N2219 could be a suitable transistor here!
(possibly with a cooling star)
.
unfortunately this is not a real WFM Transmitter!
the modulation of this transmitter is called: reactance modulation,
with real WFM modulator there is 1 or 2 varicap diodes in it.

Nice definitely gonna try it, thanks😄👍

[@slender1357]

Didnt think the 2sc3355 was capable of outputting 0.5W, gonna try

[@techtinkerin]

Apparently it's max is 0.6 watt, not bad for no heat sink😄👍

Good video and well explained, thank-you! Please do more of these easy to follow videos on radio projects. Did you check for harmonics and interference? Probably not necessary at short range.

[@carlosmanuelsaraybeas5766]

Teacher, if your amplifier were placed at the output of an analog audio and video modulator, for example, TV channel 3, could you increase the power of the modulator signal? Which coil would you modify?

Is that a stereo transmitter and how is the sound at the radio , especially in quiet music. Is their alot of interference? I mean without your amp mod

[@techtinkerin]

Tried it, it works but not on correct frequency, maybe I have coils wrong or driver tx is not suitable. Got a tiny rf burn on my finger so it's definitely working😄

[@klausbrandt5064]

Artem can you build some more RF amplifiers for these small FM transmitters please ? Perhaps a 2 transistor design ?

[@hobbyrob313]

GREAT AGAIN for sharing this with us!
(this FM TX runs on 30 or 50MHz X(times) 3 or X 2 if I remember correctly?
questions:
We here in the Netherlands use the Japanese FM band
(83 to 87MHz - here in the Netherlands that is a pirate band! )🏴‍☠
Could the amplifier be used mainly for 85MHz WFM?

[@naufalhabibi12]

great videos!, but can I change the frequency of the module up to 300mhz by changing the oscillator capacitor?, is the transistor need to be change?

[@techtinkerin]

Transistor is good up to 6 GHz 😎👍

[@GYM.Hellgart]

want to see rf amplifier 5w 2sc1971 can you do it

[@Lukkyja]

can i use 12 volts when i have no 9 v stabilizer and amplifier?

[@MrTauron77]

BD139 vagy 2N3866-os tranzisztorral is megoldható?

[@kamikruz9214]

2SC3355
NPN Silicio
UHF

[@CB-RADlO-UK]

hello brother please can you give me the name of every piece you used

[@techtinkerin]

100nf, 100nf, 100pf, 30pf, 330ohm, 1k, 10k, c3355, 6to25pf, 0.2mm wire, 0.5mm wire. 👍😄

[@joseferreira1955]

Eu José Ferreira gostaria de saber como adquirir um transmissor FM deste

[@أحمدالطشانى]

FM Is it useful to use the C 2690 transistor

[@juandanielbernalmena6568]

I can use a 2N3553 transistor, I can't find the transistor in the video :(

[@HighVoltageArcRD]

Actually you can use 2sd882 or d882 transistor for this circuit but you need to remove the 330 Ohm bias resistor and power it with 12v

[@kumarsizhayat-r7y]

Fm verici hep ilgimi çekmiştir çubuk antenle en iyi mesafe ne kadar olur besleme kac watt veya amper olmali

[@TheSudiptheory]

Can I get pcb design file??

[@radiosignalfrecuencydx2379]

Cuantos Voltios nesecita ?

[@MrErickpe]

Very Good

[@kumarsizhayat-r7y]

Harika 3 volt da kaç metre veya kaç mwatt transmiter metre

[@manuelvillanueva3753]

Aint convinced, I tried it, not working...

[@transporder]

2sc3355 bulamadım 😢 deneyecektim

With 500mW i can communicate with my friends 5 km away using an antena as high 7 meters.
