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.
