For the most the personal computer has become the essential tool to get jobs done quicker, easier, quieter and in less space than ever before. When radio amateurs connect a personal computer to a radio, then it takes the potential of both to another level. Computers in Amateur Radio provides a practical guide to what is possible for radio amateurs who wish to combine these two technologies.

This thoroughly revised and updated edition of Computers in Amateur Radio has been expanded to include new material on the phenomenal possibilities of Raspberry Pi and the wide variety of data modes now available. Computers in Amateur Radio provides chapters dedicated to the computer modelling of antennas, propagation and even terrain for HF, Remote Operation, Software Defined Radio, APRS, SSTV and log keeping. A whole host of live Internet uses are also covered. There is even a chapter dedicated to the EMC of computers, with information on choosing systems and how to avoid - or deal with - the interference they can cause or suffer.

Computers in Amateur Radio contains many illustrated step-by-step guides to assist the first-timer in becoming familiar with an activity. For the more experienced reader there is great reference information and even some basic fault-finding and interfacing tips - everyone will find something of interest and value.

RTTY/PSK31 for Radio Amateurs
By Roger Cooke, G3LDI

Data modes appear to be a daunting prospect to newly licensed radio amateurs, but they do not have to be. This book is a practical guide to the two most popular data modes, RTTY and PSK31.

This book is an expanded and fully updated 2nd edition of the popular RTTY and PSK31 for Radio Amateurs. At 50% bigger that the 1st edition, there is no better guide to these data modes. Readers will find details of where to find data modes on the amateur bands, through getting started, to making the most from both these modes. DXpeditions and contests use these modes and there is lots of information on getting the best from these too.

RTTY is the oldest real Data mode and was first used on the amateur bands over 50 years ago. In those days it was a complex mode to use, with teleprinters and home made transmitters to modify. However, in the computer age, it is much easier to both use and set up. RTTY and PSK31 for Radio Amateurs provides you will all you need to know to get the most out of this fascinating area of amateur radio.

Free CD
The free CD that accompanies this book has also been fully updated to provide a wealth of amateur radio data mode programs to get you started. You will also find reviews of equipment, lots of reference material, videos, web links and essential reading for anybody interested in Data.

Warning
RTTY and PSK31 for Radio Amateurs does though carry a warning: Buying this book may lead to an enjoyment of RTTY, PSK31 and Data modes in general that is highly addictive.

Computers, Microcontrollers and DSP for the Radio Amateur

By: Andy Talbot, G4JNT

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.
