[Elecraft] The Dummy Load Noise Generator

Fri May 16 09:25:04 2003

Hi

I thank this happens more than most people want to admit. I put a warning in
the instructions about this but it is still easy to do. It will usually zap
the 680 ohm resistor and one or two of the transistors depending on how many
watts you fed back into the generator. It is a good idea to set the power
control to minimum then disconnect the key and/or mike when using the noise
generator and stay away from the tune button. Almost any small signal NPN
transistor will work 2n3904 2n2222 2n4401. After several glasses of some of
our fine Texas wine, I find messing about with radios is not a good idea,
but I have been known to do it anyway. ;-)
