Hi Sirma,

Welcome to the forum.

Thank you for your encouraging comments.

Germanium diodes have long been the diode of choice for non-powered crystal radio sets...which is what the Raudive Diode was originally based upon.

A germanium diode has a lower forward voltage drop than a silicone diode. While the drop may seem miniscule... roughly 0.1 - 0.2V compared to is enough to make the germanium diode a tad more efficient in using the small amount of available current generated in a non-powered radio application.

I hope this answers your question. If not, please continue to keep asking questions till you are satisfied.

Kindest Regards,
