[Elecraft] Diode Selection for RF Probes

[David Cutter]

Jack

It's really interesting to read the articles on your site.  In QST recently 
there was an article about a crystal set and a self-biased fet was used 
instead of a diode and I think it was said that this gave a higher output. 
It would be interesting to see how that would rank in your tests and might 
prove useful in a probe.
