RADIO TO CRYSTAL

This it is another radius to germanium crystal that is very sensible, although does not discriminate a frequency of another one especially if the stations are near. The interesting thing is that it does not require of batteries to work and its construction is very simple. The only devices a little difficult to find are the crystal diode and crystal earphone of germanium. Another type of diode cannot be used that is not of germanium.



The radius works better with a coil as which it is above, but is necessary to have well-taken care of which the turns are well together. For this equipment can be done winding machine that is down.

This other radius to crystal can be done:
radio to crystal with bottle
