Faculty and students of the Department of Physical Sciences at Morehead State University in conjunction with Capitol College and Kruth Microwave Electronics (K-MEC) propose to design, construct, and operate a Multi-Channel Spectrometer System (MCSS) for the Morehead Radio Telescope (MRT). The proposed MCSS is a robust, experimental platform that divides the MRT's existing 20 MHZ bandwidth into 2.4 million simultaneous narrow channels that allow the production of a radio frequency spectrum. The proposed instrument is suitable for a wide variety of experiments including galactic and extragalactic kinematic experiments and for SETI research. The system design reduces cost by utilizing surplused demodulators obtained from the National Security Agency (NSA) in conjunction with special-purpose detectors and inexpensive PC sound cards for digital signal processing. This "swords to ploughshares" approach utilizes existing resources and provides a low cost solution to high resolution radio frequency multi-channel spectral analysis. The MCSS will provide a research instrument for undergraduate astronomy and physics students and an active laboratory for physics, electronics, engineering, and computer science undergraduates and faculty. The goals of the MCSS program are to enhance the curricula in physics, pre-engineering, electronics, and science education programs by serving to provide, 1) a research instrument for kinematic investigations in astrophysics; 2) an active laboratory in astronomy, physics, electrical engineering, and computer science; and 3) a research instrument and laboratory for science teacher education and inservice programs that utilize the appeal of SETI to teach basic science concepts. The performance characteristics of the MCSS allow a varied and in-depth scientific program and are well suited to multi-frequency observations of a wide variety of astrophysically interesting phenomena. The MCSS provides hands-on experience in research and instrumentation technology utilizing a s cience that is in the midst of scientific revolution.

莫尔黑德州立大学物理科学系的教师和学生与国会学院和Kruth微波电子公司（K-MEC）合作，为莫尔黑德射电望远镜（MRT）设计、建造和操作一个多通道光谱仪系统（MCSS）。 拟议中的MCSS是一个强大的实验平台，它将MRT现有的20 MHz带宽分成240万个同步窄通道，允许产生无线电频谱。拟议的仪器适用于各种各样的实验，包括银河系和河外运动学实验和SETI研究。 该系统的设计降低了成本，利用多余的解调器从国家安全局（NSA）与专用探测器和廉价的PC声卡的数字信号处理。 这种“从剑到犁铧”的方法利用了现有的资源，并为高分辨率射频多通道频谱分析提供了一种低成本的解决方案。MCSS将为天文学和物理学本科生提供研究仪器，并为物理，电子，工程和计算机科学本科生和教师提供活跃的实验室。 MCSS计划的目标是加强物理学，工程预科，电子学和科学教育计划的课程，通过提供，1）天体物理学运动学研究的研究仪器; 2）天文学，物理学，电气工程和计算机科学的活跃实验室;以及3）一个研究仪器和实验室，用于科学教师教育和在职计划，利用SETI的吸引力来教授基本的科学概念。 MCSS的性能特点允许进行各种深入的科学计划，非常适合对各种天体物理学有趣现象进行多频率观测。MCSS利用处于科学革命之中的科学提供研究和仪器技术方面的实践经验。
