A good friend has done us a great gift, we have built a crystal set. A gallery is a radio receiver that employs a semiconductor crystal of lead sulfide, also called galena to capture radio signals in the medium wave band (530 to 1600kHz).
Only through this mineral and without any power, that is capable of receiving radio waves in the atmosphere and convert them into an audible signal.
great craftsmanship This has caused us wonder, and so we put a series of photos so you can evaluate your work of art.
If someone wants to comment will be grateful, and we will reach the creator of this radio.
