Another part of my obsession with radio is the wonderful new and old books that have been produced on the subject over the years. This copy of Short Wave Wireless Communications By A W Ladner is a testament to radio design before the age of the transistor.
This is a comprehensive guide to all things shortwave written from the engineers point of view making it heavy on the maths and calculation side of radio but if you have any interest in valve circuits there are more than enough schematics to go around.
As this revision of the book was published at a time when transistors where still only being used in demonstration radios with the first commercial product still 5 years away you can forgive the authors for not devoting space to a as yet unproven technology.
Even though some of the terminology and equipment discussed are a bit dated you cant get away from the great deal of work put into this publication with much of the number data being just as relevant today as its always been. Precision jumps out from every page (that’s engineers for you) and you can see the tremendous amount of work it took to get the book ready for sale.
Apart from the many schematics of valve receivers and transmitters one of my favorite things about this book has to be the section on typical transmitters, vintage radio has always fascinated me and the pictures of huge 1kw transmitters from that time are good to look at while being a constant reminder of how far our technology has come since the 1950 revision of this book.
