Hello friend, instead of using a capacitive trimmer to tune the radios, you could use a ceramic capacitor of 18Pf and the oscillator coil for a variable coil that would avoid breaking the trimmer in the radio station change, the inductor coil being variable instead of using trimmer. ..varying the inductance of the inductor also varies the frequency thus changing the radio stations

That's just dumb. It is much better to use a Variable Capacitor than some gimmick to make a variable inductor.

I suppose if you use the soldering iron they use to keep cows and horses together, then you can solder on the wrong side of the board.

Yeah my quality department rejected the board. I guess consumer electronics you can get away with a lot of things. That iron is too big also. The flux is easier to remove from the solder side of the board. Now where is the conformal coating just kidding I just coated 17 boards. 73

We want the same design for this circuit that you made, but for a great metal detector and a wonderful design with great depth and an easy and simple circuit that is not complicated. Everything is designed outside without a chip. We thank you for your genius, cunning, and the works that you do. A real finish is very wonderful. My greetings to you, and we wish you a happy life.

Talvez la tecnología nos siga sorprendiendo día a día, no obstante me hago una gran pregunta de como se escucha tan bien desde el inicio, sin reajustar la regeneración y sin tener conectada NINGUNA ANTENA? Lindo diseño!

Aí eu botei fé, meu brother ficou top

call me old fashioned but in my world the components go on the opposite side of the board from the solder pads when using a through hole components....

in place of the trimmer by a ceramic capacitor of the same capacitance of the trimmer and in place of the oscillator coil by a variable inductor will avoid breaking your trimmer during the change of radio station a variable inductor coil and the frequency will be changed in the inductor coil itself. the change of tune

thank you....but ...This is am radio, not fm

Espetacular !!!

You are to solder on the other side. That's why it's called the solder side. I would reject the work or the QA department would. We learn in communication electronics is more critical than consumer electronics so I guess that grade would pass. Nice video and good camera work. 73

il problema è che oramai non esistono più i negozi che vendono componenti per elettronica! oggi chi vende resistenze condensatori o transistor è praticamente impossibile. resta internet, ma non ti vendono una resistenza un condensatore, ecc. devi acquistarne in quantità! spesso la spedizione costa 10 volte il valore di quello che acquisti

Is the best

This video has so much wrong with it, and is so choked with commercials for Altium Designer, it plays like a scam. No schematic is shown, and the component count, and component types, looks barely able to receive AM signals much less the more complex FM signals. There are a lot of webpages that investigate the simplest FM receivers, and they all have a lot more going on than this one, but at least with their schematics we can see how they work. Add to that, even if all transistors on the PCB are cleverly used to receive the FM signal, it sure looks like there is a deficit on remaining transistors to drive the 8 Ohm speaker, something that usually requires a few gain stages. The video shows a pot and a couple trim caps being slightly adjusted, and for all we know, this is a fake where the circuit is not even doing anything, but a separate soundtrack is superimposed. And who does PCB assembly by hand using tweezers, and soldering from the component side? Suspicious. Without a schematic to add veracity, I think this is fishy.

Fishy is being ever so polite.. Min basic FM radio should have many more stages. Tuned front end, Local oscillator, mixer, IF amplifier and detector stages and audio amplifier. Not only do you need to hear the station you want the others need to be blocked or filtered out. People need to do a little research on receivers. This is nothing more than a Cats whisker radio that was used on AM.

What is the resonant frequency you are focused on. Sorry I haven't been looking for 1 uH. 33 turns sounds like a choke rather than a resonant tuned cct. I can make here and measure for you if that helps.

I made this radio receiver today and it received just one station at 89.1Mhz frequency. The quality of my receive is poor with a lot of harmonics. I don't know where my problem is coming from! I got every other thing right except the coil, I used SWG of 23 and obtained a six turns on a 5mm core. I don't what I should do to receive other frequencies and improve the quality on my radio. I was super excited because this is my first radio receiver ever built....
