The ARRL Satellite Handbook by QST Editor Steve Ford, WB8IMY, brings the thrill of satellite communications within your reach. Filled with understandable descriptions and illustrations, this book includes all the tools you need to participate in this exciting field.
This very readable guide was designed to give a broad introduction to the subject of satellite communications, while providing the practical fundamentals you need to explore, track and operate ham radio satellites on your own. Since the pioneering days of satellite communications, ham radio operators have been along for the ride -- building, launching, and operating satellites. You can experience this technology firsthand using today's fleet of Earth-orbiting ham radio satellites.
Including content by satellite expert Martin Davidoff, PhD, K2UBC, this book is sure to be a hit with both new and experienced satellite enthusiasts. Be sure to get your copy of The ARRL Satellite Handbook today!

Before the Internet, the ARRL's Radio Amateur's Handbook was the single comprehensive textbook for radio amateurs. Radio amateurs treated the handbook like a family Bible: they might replace the handbook as technology evolved, but they never discarded older handbook editions. The handbook grew every year. The 1966 edition has 601 numbered pages plus numerous spec pages, discussing vacuum tube circuitry in great detail but hardly discussing semiconductor technology. The 1977 edition has 664 pages plus numerous spec pages, and discusses both vacuum tube and semiconductor circuitry. The 2008 edition switches to chapterized page numbering, but the 2008 handbook is equally thick in a larger page format, and semiconductor circuitry [including analog and digital integrated circuits (ICs)] predominate in the 2008 handbook.
The handbook contains sufficient detailed information to teach amateur radio communications. Each handbook has sections covering electronics component theory; fixed and mobile power supply design; receiver, transmitter and antenna design; construction practices and test measurements; and radio operations non-interfering practices. The handbook's operating modes discussion expands as technology evolves: the 1966 operating principal modes are Morse code and voice (AM/FM/SSB). In 1977 the operating modes expand to include digital terminal-based teletype (TTY) and slow-scan television (SSTV). And the 2008 handbook adds digital operating modes: satellite communications, (data) packet radio, and voice-over-Internet-protocol (VoIP) speech.
This handbook provides a high level overview of the amateur radio satellite (AMSAT) program, discussing AMSAT history; satellite orbit types and procedures for tracking the non-geostationary AMSATs; antenna and transmission line considerations during AMSAT operation; transmitter and receiver considerations during AMSAT operation; and operating protocols used during AMSAT operation. The handbook ends with a collection of (primarily antenna) construction project articles, and two technical appendices discussing satellite orbit and satellite physical subsystem details.
The ARRL Satellite Handbook is a useful introduction to the AMSAT program, but its descriptions are not sufficient to implement an AMSAT working ground station. The handbook indicates the complexity and the cost of building a predictably-working AMSAT ground station, a project IMO best accomplished through an amateur radio club's shared station.
Imagine the most eager-beaver optimistic amateur radio novice: I'm gonna purchase / construct state-of-of-the-art bleeding-edge communications equipment! I'm gonna be great balls of fire! An antenna is at the bottom of the eager-beaver's priority list, even though a superior antenna best improves a radio station's performance. The ARRL Antenna Handbook contains 28 chapters and over 700 pages of detailed yet practical advice on radio antenna configuration and construction, a comprehensive encyclopedia of radio antenna design. The handbook has evolved over fifty years as knowledgeable radio amateurs developed antennas for every conceivable situation, both for their club and home stations (their ham shacks), and also for their in-the-field expeditions. The handbook covers just about any situation, including attic antennas and electrically loading a residence's aluminum storm gutters as an invisible antenna in areas having zoning restrictions. The included designs range from simple, low cost antennas to stacked antenna arrays on high towers requiring a lineman's maintenance skills.
An amateur radio ideal backyard has an unobstructed sky view and abuts a lake (sandy beach optional). I purchased my current residence (QTH) in 1978. My QTH's backyard is surrounded by (HF) masonry buildings on the north and the south. My QTH's backyard is surrounded by (VHF / UHF) large trees on the east, the south and the west such that my next door neighbor experienced summer leaf trouble with his commercial TV satellite dish. Despite the handbook's wealth of antenna practical solutions, my QTH remains antenna-challenged.
The United States Marine Corps has extensive experience providing field communications in diverse environments. Antenna Handbook MCRP 8-10B.11 is a one-volume guide instructing mathematically-minded Marines in field antenna construction. Amateur radio operators can benefit from Marine Corps practical experience; and best of all, the referenced webpage provides a link to a no-cost downloadable PDF-formatted version of the handbook.
While it does not take a great deal of radiated power to work LEO Sats, a fairly sensitive receive system is required due to the low transmit power used for the downlink on these birds. We are planning to mount the antennas for our satellite system at around the 90 ft level on our tower. This distance plus the run from the tower to our shack will result in a total feedline length of about 190 ft. To ensure that the feedline losses do not compromise the performance of our satellite system, we have decided to install tower-mounted Low Noise Preamplifiers (LNAs) on our tower near the antennas. We are using a 2m LNA Preamplifier from M2 Systems and 70cm LNA Preamplifier for Advance Receiver Research.
We have been doing quite a bit of reading to learn about how to design and build our Satellite System. One excellent source of information on this topic is the ARRL Satellite Handbook. I can recommend this book as a great source of information for anyone considering the construction of a satellite system and for those interested in learning more about satellite operations. 2b1af7f3a8
