This book is for the radio amateur and home experimenter who wants to use modern digital and computer technology to make more use of his/her radio equipment. It is aimed at those who want to add additional hardware and try new signalling and communications methods, and to build hardware and systems for controlling existing equipment. The home computer is first covered, writing programmes and software, with much detail on how to interface the PC to external hardware via its various ports. Particular emphasis is placed on what can be done with the older computer, now very cheaply available. Software techniques for detecting signals in noise and for automatic beacon monitoring are described.
Then come Microcontrollers, covered in depth, particularly the PIC family of devices. From the basics of writing the first PIC programme and programming the device, many different types of hardware are described, such as A/D converters and relays. This includes simple arithmetic and coding issues for security and remote control. Finally, basic Digital Signal Processing is covered, with aspects such as digital filtering, time/frequency transformations and very narrow bandwidth working being described. How to start using DSP techniques at home is explained; evaluation modules and DSP routes using some simple additional hardware and a PC are covered. Programming in the Windows operating system, with particular emphasis on using the soundcard for DSP purposes, is then introduced.
Written for the experienced amateur, this book is aimed at the experimenter and home constructor who wants to get involved in the subject, and to understand how to take it further.
