It’s here! The ARRL Handbook for Radio Communications for 2021 — your complete guide to radio experimentation, discovery, and innovation — now is available. The Handbook is written by radio amateurs for everyone who has a desire to advance the pursuit of wireless technology. It’s available in three formats: Traditional softcover, a six-volume, shrink-wrapped book set (box not included), and eBook digital editions.
The 2021 Handbook features new projects and tools, including an FET-controlled power switch, transmitting tube tester, 432-MHz utility Yagi, off-center-fed dipoles, a loop for 30 and 40 meters, RF sniffer construction, RFI loop antenna, and more. This invaluable resource offers new material on the behavior of RF chokes; circuits for PIN-diode RF switching; adding SDR panadaptors to older radios; digital modes FT4, FT8, and MSK144; care and feeding of power grid tubes; new feed line chokes for receive and transmit; ac power connector types and wiring, and more.
The Handbook Six-Volume Book Set, ARRL Item No. 1403, ISBN 978-1-62595-140-3, is $59.95 retail. The Handbook Softcover Book, ARRL Item No. 1397, ISBN 978-1-62595-139-7, is $49.95 retail.
