  I am interested in building a relatively inexpensive (Approx $100) spectrum
analyzer for use with my Tek 535 'scope.  I have heard of plans for using a
varactor-tuned television tuner and some form of logarithmic IF amplifier
to provide the Y signal to the scope.  Has anyone built one of these?

  Does anyone have a reference to an article describing plans for something
like this?

  Thanks.
