Technology history
Discover some of the stories that detail how the foundations were set in place for today's technology.
We have a large number of pages devoted to pioneers, how technology was invented and developed as well as descriptions of many types of radio receiver, etc, etc.
Classic Vintage Radios
Since the first radios were developed, many different radio designs have come and gone, but some stand out or are remembered as classic radios of their time.
Electronics Notes aims to provide accessible summaries about a host of electronics, radio and connectivity technologies in a practical and useful way.
Our aim is to support those who want to learn about the technology: those who are established engineers as well as students and hobbyists.
The topics included in the site range from the basic electronics concepts (useful for established engineers as well looking for those equations, formulas etc, including topics like basic electronics concepts, component descriptions and explanations, circuit designs and circuit design principals, manufacturing techniques, radio technology & RF design and wired and wireless connectivity and a host of other topics.
To fund the running of the site, we obviously need to carry advertising, but we aim to make this not too intrusive. We hope you understand, but we need to have income to meet the not inconsiderable running costs.
