Fiddling with the dials trying to get signals to be understandable is half of the fun when using a Regen. Not the best radios for casual listening, but lots of fun.
Many years ago I had a 2-transistor arrangement courtesy of a kit, possibly made by Philips and on just a ferrite rod was surprised how well it pulled in the stations. By comparison, the battery tube radios I made in the early 60s needed an outside antenna to do something similar.
what are the Values for L2-MW and L2-SW ?. The question is based on the very high possibility that my ferrite rod might have different properties than yours and will yield a value that will not get me to the correct bands. Withe value I can build my coils very close to what you have in yours.

Salut !Fain proiectul!De unde ati achizitionat modulele de amplificare.Cele pe care le-am cumparat au probabil un factor de amplificare de mai putin de 20 de ori cu toate ca ar trebui sa fie 200.
Salut! Este constructie proprie. Am incercat tot felul de variante constructive, pana am ajuns la forma de la minutul 8:59. Am incercat si cu 3 etaje de amplificare, insa montajul devine prea sensibil, probabil trebuie realizat intr-o carcasa metalica.
@@dz-abouttechnique1849Mă refeream la amplificarea audio. La minutul 9:02 se vede ceva care seamănă a modul de amplificare audio lm386 ... Dar oricum e frumos radioul! L-am constituit și pe cel cu "reactie" AM și am reușit să îl fac să meargă. De fapt am făcut vreo 3 . La cat mai multe videouri!
It's amazing what you've done with so relatively few components.
Thank you!

That is why a superheterodyne is in the works.

I love the Manhattan style breadboard/components!
Thank you!
Hello, very nice.
Where is the diode detector?
Or is it integrated with the amplifier chip?
Audio signal detection is performed by transistor T1.
@@dz-abouttechnique1849 Thank you very much

excelente buen tabajo no savia que podias usa ese circuto asi muy bueno
Thank you!
It's amazing, impressed.
Thank you!
Boa noite. Me tire uma dúvida por favor. O T1, poderia usar também o BC 548, 2n2219? Obrigado.
Teoricamente... sim. O receptor provavelmente ficará instável.
@@dz-abouttechnique1849 Boa noite. Em SW sintoniziu a banda de 40Metros? Radioamador.
I’m curious. Why did you use a potentiometer and not a variable capacitor to control the regeneration setting?
Read the description.
Very nice project!!
Thank you!

@@dz-abouttechnique1849 L2 not K2, sorry for the typo.
@@noelrodriguez I don't have an inductance measuring device. I estimate as follows: L2 MW: 550 - 600 uH. L2 SW: 10 - 12 uH.
Good luck!
@@dz-abouttechnique1849 thanks, I will add more turns and test, removing some as i go till they are in range..

Awesome . Great work 👍👍👍👍

Aha. Scuze. Am ramas blocat pe frecventmetru 😂. Intr-adevar este cu LM 386. Multumesc!@@instructoruldemeditatie2367
nice job! 20 turns is for 40m band?
Yes.
What did you use to scribe thru the copper?
Cutter.
I have a question
What is the range of mw and sw that we can receive with this radio????
Pleas answer
MW/SW maximum 2000 km.
This device has excellent performance: ua-cam.com/video/ApwX6qniuos/v-deo.html
can this receive ssb-lsb-usb and if so does this have a BFO? thanx
From experiments, it works between 500 Khz and 7 Mhz.
Seçicilik Nasıl ? Komșu istasyon Karıștırması Yapıyormu ? 🤔
İstasyonlar çakışmıyor. Mümkün olduğu kadar çok istasyonu alabilmek için bir anten gereklidir.
Very good
Thank you!
رائع
Thank you!
Its SSB yes?
What tool was used to cut the grooves?
Cutter. Good luck!
please give details how make L3 RFC coil by resister
Resistor 100 k + 20 turns. Minute 0:10
L3 if done in a small rounded ferrite core or plastic pen refill as inductor their was any problem in reception??
Not. The coil is not important. It also works without a coil. Use a 1 - 100 ohm resistor.
How to switch between waves There is no switch in the circuit diagram
The MW coil (90 turns) is replaced with the SW coil (20 turns).
