[Elecraft] P3 Noise signature

[Bob]

It can be used as a visible-receiver/spectrum analyzer by setting the "IF" 
frequency to the piece
of the spectrum you want to look at.

In the manual see Advanced Operating Procedures "Use with Other Radios"

It may be a "poor mans" spectrum analyzer but in my opinion not a poor 
performance one
especially if you have it on hand and this is a free feature.
