i tried to make three signal/radio frequency/radiation detector (please tell me if there are any differences between the three since i dont really know what i am doing), but none of them worked. what did i do wrong? is it me? is it the diode? the capacitor? the transistor? the coil? all of the above (i hope not)?

in this one, i read in some of the comments that it is fake or does my coil need to be a 24 awg?

in this one, i suspect that my diode was not what it was meant to be which is why i made this thread:

in this one, my buzzer rings the moment i stick the red wire into the middle pin. i suspect that my transistor & diode are both not as what they were advertised, if so then can someone please share & paste a link of a trusted seller in here on where i can buy legit transistors & diodes that i need for all these?
i will truly appreciate any sort of advice & or help that i could possibly get in here.
thank you very much
