About 'A Practical Guide To RF In Broadcast'
A Practical Guide To RF In Broadcast is a Themed Content Collection that will publish during 2023. The complete series of twelve articles provides an extensive technical guide to RF technology within broadcast. It is a major work that will serve as a reference resource for professional broadcast engineers.
Broadcasting has encountered more technology change over the past thirty years than many of us care to think about. Analog has changed to digital delivery, SD has changed to HD and 4K, and sound is transitioning to deliver higher levels of immersive experience through object and surround sound. But the one consistent technology that has stood the test of time is RF.
RF differs from most other broadcast technology as it’s fundamentally analog. As the laws of physics haven’t changed in the past hundred years, then the underlying rules that govern all RF systems haven’t changed either. But what has changed is how we use RF in the context of modern broadcasting along with our understanding of how waves propagate through the universe.
Broadcasting has always driven technology to its limits, and this is certainly the case with RF. Morse devised the first channel coding system ninety years before Shannon formalized his achievements through information theory. And this in turn led to the development of the highly efficient coding systems that we use in modern broadcasting such as CODFM and 5G-NS.
Our RF understanding is sure to improve for as long as users continue to use mobile devices.
A Practical Guide To RF In Broadcast is a collection of twelve articles presented in four parts.
Each part tackles a different theme and there are three articles per part.
Details of all four parts can be found HERE.
About Part 1. History, Modulation & Regulation
Part 1 is a free PDF download which contains three original articles:
Article 1 : The History Of Broadcast RF
We start at the beginning... Wireless delivery of news, messages and data is older than wire itself!
Article 2 : Broadcast Modulation
Defining the different types of RF modulation, power levels, regulatory standards and licensing for CW, AM, FM, and TV RF transmission.
Article 3 : Government Spectrum Regulation
The regulatory bodies such as the FCC, ITU and national governments, and how RF standards and regulations are set and enforced.

Microphones: Part 9 - The Science Of Stereo Capture & Reproduction
Here we look at the science of using a matched pair of microphones positioned as a coincident pair to capture stereo sound images.
Microphones: Part 8 - Audio Vectorscopes
The audio vectorscope is an excellent tool for assuring quality in stereo sound production, because it makes the virtual sound image visible in the same way that a television vectorscope allows the color signals to be seen.
Microphones: Part 7 - Microphones For Stereophony
Once the basic requirements for reproducing sound were in place, the most significant next step was to reproduce to some extent the spatial attributes of sound. Stereophony, using two channels, was the first successful system.
