Scott Gardner, Comm Engineer

About Me:  I am a Communications / Network Engineer I have over 38 years experience working for the Air Force.  I have worked on Ground to Air and Land Mobile Radio systems.  I have also spent the last 15 years working on Networking systems.  I set up this site to provide information to the class I am teaching at SWIC on Communications Electronics as well as my new class EET121 semiconductor basics , so it will not be fancy, but may be useful.  I hold a Professional Engineers license in Illinois.
