How important is the forward voltage rating on a crystal radio diode.? Answered
I have been researching how to build a crystal radio, and have built a few from schematics I have found on the web (though none have worked so far). The thing that is confusing for me is the range of forward voltage ratings I have found. Some of the part numbers I have come across such as 1N34A show a forward voltage of 1 volt. While others recommend 500mV and others as low as you can get.
With so many instructions saying different values for best results. Is there a recommended rule of thumb for choosing a diode for a radio detector?
