There have been several articles in Ham Radio magazine about the
"Poor Man's Spectrum Analyzer" available as kit modules from Science Workshop.

The latest Amateur TV Quarterly (ATVQ) has an ad for it which says that
it now covers from 2 MHz to 1500 MHz. Send a SASE for details. I've sent for
the information but haven't received it yet.

The only address I have handy may not be the current one (the PO number may
be different) but they are still in Bethpage.
