*  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?

1-100 Mhz Spectrum Probe  $249  Smith Design, 1324 Harris, Dresher PA 19025
(215) 643-6340

60dB dynamic range 
5mV/dB vert output
linearity +-3dB
60uV sensitivity at 50 Mhz
180Khz IF bandwidth

I have never seen one of these.  I just have an advertisment for it.
