Getting Started in EME
Bouncing signals off the moon has always been considered as one of the most difficult of the amateur radio disciplines. Traditionally, Moonbounce (as it's known) was practiced by amateurs who are the most accomplished engineers, as well as operators—but recent developments have now made it more accessible than ever before. "Getting Started in EME" sets out to explain what you need to know and how to get started in this captivating area of amateur radio operation. This 64-page paperback sets out the history of Moonbounce, gives information on the various EME bands, and the reasons for choosing them—and then explains the EME signal path. It covers the unique propagation effects, such as libration fading, Faraday rotation, and spatial offset. Ground gain, Doppler shift, and degradation are also covered. The book is practically based and focuses on EME at 144MHz (2m) and proposes, wherever possible, the use of equipment that is already owned in order to reduce the cost of getting started in EME. This is particularly the case with antennas, but you'll also find coverage of transceivers, pre-amplifiers and power amplifiers. Again, the emphasis is on the minimum possible requirement, utilizing equipment that may already be in the shack. There is coverage of computers/interfaces, software and operation requirements, and even your first EME contact! EME at 70cm is covered, and there are glimpses where the newcomer to EME might move onto when they find themselves bitten by the Moonbounce bug. If you've never tried EME transmissions or are just interested in what it takes to make that first contact via bouncing a signal off the moon, then "Getting Started in EME" is the ideal introduction.

HAMSAT
Since the launch of Sputnik back in 1957, radio amateurs have been listening to artificial satellites orbiting above the Earth. A mere four years after the launch of Sputnik, radio amateurs put their own satellite into orbit, thus beginning a series of amateur satellite launches that continues over 50 years later with the CubeSat operations of today. "HAMSAT: Amateur Radio Satellites Explained" offers details of what you need to know about amateur radio satellite operation. This 128-page paperback begins with the history of the OSCAR (Orbiting Satellite Carrying Amateur Radio) program, detailing the various incarnations from Oscar 1 in 1961 through to the present day. The book explains what's needed in an amateur radio ground station, from the antenna to the receiver. You'll find rotator information for tracking the satellite, designs for pre-amplifiers, and all manner of technical detail. There's a chapter dedicated to the ground station antennas, sharing the performance of many commercially available systems—and information on The Endless Dilemma of Polarization. You can read about Ground-Space-Ground Propagation, the Doppler Effect, Keplerian Elements; plus suitable transceivers, software, recent developments in this exciting field, and much more.
