We have converted a Haystack-design small radio telescope (SRT) using a Labview virtual instrument control and user interface. In addition, we replaced the original Haystack digital receiver with a conventional superheterodyne receiver and 1024 channel autocorrelator. The advantages of this system over the original Haystack design are (1) a more modular, user-configurable interface, (2) a receiver system similar to traditional radio astronomical receivers with many test points accessible to students, and (3) better system sensitivity, since the entire 21 cm HI velocity range (2 MHz) is sampled simultaneously. We use this system to teach students the fundamentals of radio telescope and autocorrelation receiver instrumentation, as well as galactic rotation using the 21cm HI line. The Labview VI code will be available by Janu-ary 2007 at http://astro.physics.uiowa.edu/srt
