Good job . There is something you should know. Which is that you can make the radio frequency coil slide over the ferrite rod and show you other radio stations that do not exist when it is fixed. I used to do this like this.
I don't see why the IFTs were rewound to get 145 kHz, and builder did not keep the std 455 kHz of the IFTs, adjusting the Osc coil to suit since he was winding a new osc coil anyway. Also, I agree with a previous commentor that the design is not simple. Nevertheless, it is useful to an experimenter in that it incrementally builds upon the previously buily Reflex TRF radio. Also, I would have replaced the bulky 2-gang Tuning Air capacitor with varactor diode tuning with a 10-turn potentiometer. But, this is a really good effort from which others can lrarn to mix-and-match! Bravo !
@@dz-abouttechnique1849 You mean by way of the reflex stage? How do you accomplish tracking? I don't understand why IF of 140kHz is choosen but I like this hands-on project very much. Congratz!!
@@erikdevriese671 Thank you! I chose the intermediate frequency of 140 kHz because there are fewer parasitic signals. I didn't understand what you mean with the first questions...

@dz-abouttechnique1849 you are welcome bro 👌🏻🌹👍🏻

Scheme simple si foarte interesante. Practic si functional. Felicitari!
Multumesc!

Thank you for your comment.
nice job i was like you when i was young . i do winde IF and i made Radio reciver
Finally, it is not simple at all. One modul, second, third....
Muito bom genial 😊 moro no sul do Brazil❤❤❤❤❤❤❤❤❤❤❤
Saudações!
That's excellent project , i am happy for you , in next videos make video on transmitters like medium wave, shortwave and fm transmitters
I'll try. Thank you for your comment.
Very good.
Thank you for your comment.
Сначала наматывается катушка связи а потом поверх неё основная катушка, так сделано в импортных супергетеродинных приёмниках
Я так пробовал изначально. Посредственные результаты.
Can you please share full schematic. 🙏
You can find it in the video. Even the details of the coils.
@ Im asking about small green pcb connections. From its which point connecting to new circuit.
@@mkpeker Instead of the LC input circuit. Look at the diagrams carefully.

romania ?
Da, cred ca e in Romania ca se aude baliza aero de la aprox 521
Simple...??????
The coils are simple. The explanations are sufficient. Good luck!
tantas cocegas na montagem mas para quê ? devia estar tudo montado juntinho para não haver interferências ,,,mas ficou bom ok para cima 37
Para observar a funcionalidade do oscilador. Obrigado!
Hello! Interesting device! But there is no AGC - on some loud stations sound is distorted.
AGC is working. 🤓

@@dz-abouttechnique1849 OK! I will try it myself. Thanks!
