SIP329 AM/CW/SSB Radio Receiver

This radio receiver insertion panel training course is designed to introduce the student to radio communications via free space and the ionosphere. With an appropriate outside antenna, the world of shortwave listening will open up to the student. The comprenhensive manual presents the principles of radio receivers, radio wave propagation, world-wide time signals, UTC, and the measurement of various radio receiver parameters including sensitivity, selectivity, and minimum discernible signal (MDS), path loss, and noise plus laboratory experimentation, review questions and answers.
