It has been five years since I edited Microwave Project 2. Since then the devices and equipme nt available to amateurs interested in the microwave bands has continued to increase . This book contains some of the things that are being used right now and some the surplus equipment that has come onto the market that can be modified for use on the microwave bands. The articles on surplus equipme nt have been taken from Scatterpoint , the magazine of the UK Microwave Group , this is a very active group an I recommend that any amateurs in the UK should get along to one of the meeting that are held around the country to see how useful being part of this group can be to get the most out of the microwave bands.

There are similar groups in many other countries that I an sure would be just as helpful if you do not live in the UK. So that readers will not think this is just a face-l ifted version of the earlier Microwave Projects books it has been decided to give this book a new more descriptive title. Many of the articles require a PCB, the artwork in this book is not reproduced to exact size, so if you are going to make you own PCBs please take care to scale the artwork correctly. I recommend that you taken easier option because most of the authors can supply PCBs and I have included contact details where possible. Many of the contacts are email addresses or web sites, unfortunately these have a habit of changing, they were current at the time of editing (January 2010). If you have difficulties with PCBs, finding components or contact details please contact me and I wi ll try to help.
