  We have developed a set of college level, table-top labs that can be
performed with an interferometer using satellite TV electronics and compact
fluorescent lamps as microwave signal sources. This interferometer, which was
originally developed at the MIT Haystack Observatory as a Very Small Radio
Telescope (VSRT) to observe the Sun, provides students with hands-on experience
in the fundamentals of radio interferometry. These labs are easily performed
and convey an intuitive sense of how combining the signals from an array of
antennas reveals information about the structure of a radio source.
  We have also developed a package of java programs, called "VSRTI Plotter",
which is available as a free-download, to facilitate the data processing and
analysis of these labs.
