[Elecraft] Noise gen

[W3FPR - Don Wilhelm]

Steve,

A calibrated noise source is not necessary for aligning the K2 filters - 
most any source of noise will do.  I have even heard that some folks were 
successful with a bit of wire placed close to a lighted flourescent lamp.

If you have other needs for a calibrated noise source, you can also use it 
for the K2 alignment, but that is much more than is needed for aligning the 
K2 filters.

73,
Don W3FPR
