Zener Noise (was: 1N4007 varactors)

I'll buy that you can feed it with a resistor for broadband, but in my humble opinion the construction of a grain of wheat bulb won't get up into the UHF region with noise. Do you have any idea of the output level of this circuit? Jim "Mark" wrote in message oups.com... I have seen a small "gain of wheat" type light bulb used as a noise source... Feed it with DC through a choke and AC couple the noise out .... and you can vary it too!! Mark |
