⚠ God has said in the Quran: 🔵 { O mankind, worship your Lord, who created you and those before you, that you may become righteous - ( 2:21 ) 🔴 [He] who made for you the earth a bed [spread out] and the sky a ceiling and sent down from the sky, rain and brought forth thereby fruits as provision for you. So do not attribute to Allah equals while you know [that there is nothing similar to Him]. ( 2:22 ) 🔵 And if you are in doubt about what We have sent down upon Our Servant [Muhammad], then produce a surah the like thereof and call upon your witnesses other than Allah, if you should be truthful. ( 2:23 ) 🔴 But if you do not - and you will never be able to - then fear the Fire, whose fuel is men and stones, prepared for the disbelievers.( 2:24 ) 🔵 And give good tidings to those who believe and do righteous deeds that they will have gardens [in Paradise] beneath which rivers flow. Whenever they are provided with a provision of fruit therefrom, they will say, "This is what we were provided with before." And it is given to them in likeness. And they will have therein purified spouses, and they will abide therein eternally. ( 2:25 ) ⚠ Quran

Labelling the TA7642 as a JFET is completely misleading. That's an entire AM decoding circuit in a three terminal device, not a simple transistor. Also, good luck trying to find variable capacitors that are the right size these days. They are very hard to come across. To people watching this -- if you want to build an actual AM radio from a kit, I highly recommend the Elenco AM-550CK. You'll learn a lot more, and end up with a great AM radio for the AM broadcast band.

The ferrite inductor actually used is certainly many times stronger than the little coil in the display image. With that little coil the tuning range would be perhaps in the vhf spectrum.

Wrong. What do you mean "display image" if you care to look at the data sheet, the ferrite aerial concurs with the datasheet guidance.

cz-7642 není polem řízený tranzistor ale integrovaný obvod s 10 tranzistory a funguje pouze při 1.5V a maximální kmitočet okolo středních vln(cca2 Mhz) u nás se již středovlnné a dlouhovlnné vysílače vypnuly takže to mám pouze jako dekoraci.Nyní používám regenerativní tranzistory při 1.5V na VKV.

You might be surprised to hear a signal or two on it, if you connect it to a long wire antenna, and use a good ground. There is NO WAY that it will receive signals from any distance...if you use it, with just the antenna coil shown.
