I have built N0SS's
wideband noise generator. The
noise generator was built in a small metal box in combination with a 1
MHz marker generator. The marker
has been implemented using a
simple packaged crystal oscillator.
The noise generator is used for setting up the K2 filters using a
spectral analyzer program, and the marker generator is used for
aligning old radios.
