This is a four-part series.
Module 1 – Medium Wave/AM Radio Systems
Originally streamed October 26, 2023
This session furthers the presentations of the Basic RF for IT Series that looked at the individual pieces. Module 1 and subsequent modules of the Applied RF Series will take a more systemic approach, looking at how the pieces fit together to create the broadcast signal.
Instructors: Jeff Welton, Gary Cavell
Module 2 – VHF/FM Radio Systems
Originally streamed November 16, 2023
This session looks at the FM signal in more detail, discussing the various exciters and amplifiers, halfwave vs quarter wave cavities, and providing more detail on filters and combiners. Which combiner to use under what circumstances and how best to minimize spurious signals in complex multi-station transmitter sites is discussed.
Instructors: Jeff Welton, Gary Cavell
Module 3 – VHF/UHF Television Systems
Originally streamed January 18, 2024
Module three moves into the television spectrum to look at VHF/UHF broadcast. There will also be significant discussion on ATSC 3.0 – but realize there are already plenty of courses about that topic, so, in this webinar we will focus more on the RF aspect such as generating the signal, broadcasting the signal and what can be done to optimize coverage – height versus antenna gain, maximizing MER and what that means and similar topics.
Instructors: Jeff Welton, Cindy Cavell
Module 4 – UHF and Above – Microwave Systems and Satellite Systems
Originally streamed February 15, 2024
In session four, we go from megahertz to gigahertz and look at the really high frequencies. At this wavelength, a drop of rain can act as an attenuator. In this session, we’ll try to answer: What can be done to maximize reliability? How can redundancy be built in? What are the options for most improved performance?
