Since I didn't pick the correct numbers for last week's big Mega Millions
drawing, I am again looking for cheap equipment.
I remember seeing a home brew "relative" noise figure meter somewhere. It
would not give you an absolute noise figure number, but it would move a
needle one way or another to show how your tweaks are affecting the noise
figure of the device under test.
Does anyone know what this is or where I can find a link to it?
