CQ, usesd as a general call for initiating a contact, took time to become an acceptable practice in the early years. Serious operators frowned on its use, mostly because it had been used to excess in the old days among the “little boys with squeak boxes,” usually in exceedingly long and sparsely identified calls. In March 1921, QST announced an operating event called the “ARRL CQ Party,” to be run on April Fools Day.1 The writer (unnamed) asserted that CQ … Continue reading
After the initial thrill of being the first to hear transatlantic signals, Paul Godley’s next thought was of making contact, and a helpless frustration at not having equipment to transmit a reply. And now, emboldened by the successful second set of transatlantic tests in December 1922, many amateurs were talking about the possibility of a first two-way contact across the ocean. In fact, in early 1923 US hams were already informally running two-way tests with Leon Deloy, French 8AB (one … Continue reading
While the causes for QRM were well understood, mostly man-made, and could be dealt with through cooperation and tuning techniques, other disruptive on-air phenomena were clearly beyond such controls: those caused by nature. Some, such as static (QRN, also called strays), although understood to a large degree, had no known effective remedy. Others, such as fading, were not understood at all. At constant transmitter power, what natural phenomena could possibly cause a signal to fluctuate in strength? Why wasn’t a … Continue reading
