In the spirit of the popular QRP Classics and QRP Power published in the 1990s, More QRP Power is an anthology of articles from recent issues of QST and QEX magazines covering construction practices, transceivers, transmitters, receivers, accessories, and antennas. Here are dozens of projects and articles to help you assemble or improve a QRP station for home or travel.
QRP means radio operating with low power—5 watts or less. If you are used to operating with a 100 watt transceiver, you may wonder why anyone would do this.
Radio amateurs (hams) enjoy the magic of communicating over the air with their own equipment, without the benefit of the billions of dollars worth of infrastructure working behind the scenes to power the telephone and Internet.
QRP operators take that one step further, communicating over the air with simple equipment and antennas and only a few watts of power. They savor the satisfaction that comes with finishing a challenging radio contact. They enjoy assembling a tiny station that they can take anywhere, getting on the air with a radio the size of a paperback book and an antenna that folds up into a briefcase or knapsack.
Why not give QRP a try? And if you are already addicted, why not try a new antenna or accessory? Whether you want to build a complete station from scratch or just an item or two to use with your kit or commercial QRP transceiver, you'll find it here.
