Sure thing, what does it need to do?

I need some help with similar project ... plzzzzzz

Mauro,

You can use a Ge diode if it is all you have, but the Si schottky 1N5711 will probably be more sensitive at higher frequencies.

With the biasing even a common 1N4148 or similar Si detector will work fairly well. The biasing might need to be tweaked for different diode types. The MPSA18 is a good choice for the transistor as it has quite a large current gain.

Regards,

Alan

About VHF project

I have some Germanium Diode ( OA) I can use insted 1N5711 ?

Can I have scheme of VHF Prototipe ?

TKS

Cngratulation a very great demonstration - Good Article

Fantastic - I will try to build it-

Can you help me ? with some comments and others ?
