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.

Subject: [Elecraft] Diode Selection for RF Probes
I've looked at three diode types today (Schottky, germanium and silicon)
to see how they might perform in a simple RF probe over the range 2-21
MHz.
The details are at
http://www.cliftonlaboratories.com/diodes_for_rf_probes.htm
Rankings are (no surprises here) germanium first, Schottky in the middle
and silicon bringing up the rear.
