-
- A zener diode operated at a current below its regulated voltage
- is an excellent noise source and will generate noise well up into
- the UHF region (don't know how low in frequency they start--I have
- checked them at 1MHz where they are good generators).
-
- It is worthwhile to test a few diodes if you are looking for
- highest output. A three stage transistor amplifier operated with
- a 9V transistor battery will produce a high level of output.
