vintage amateur radio
Vintage amateur radio is a subset of amateur radio activity, considered a form of nostalgia or hobby much like antique car collecting, where enthusiasts collect, restore, preserve, build, and operate amateur radio equipment from bygone years, most notably those using vacuum tube technology.
Popular modes of operation include voice communication using amplitude modulation (AM), and Morse code using continuous wave (CW) radiotelegraphy. Among enthusiasts, there is considerable interest in owning, restoring and operating vintage military and commercial radio equipment, much of it more than 40 years old. Some undertake to construct their own gear, known in ham slang as homebrewing, using vintage parts and designs. A number of amateur radio clubs and organizations sponsor contests, events, and swap meets that cater to this specialized aspect of the hobby.
== Appeal ==
Many amateurs prefer the relatively precise digital frequency displays and stability of modern, state-of-the-art, microprocessor based amateur radios. Vintage radio enthusiasts contend that modern amateur equipment lacks the aesthetic appeal and "soul" of amateur electronic gear from the vacuum tube era. Additionally, many find satisfaction in taking commercially-made amateur equipment from the 1930s-1970s (affectionately called boat anchors by US amateurs〔 because of their large size and weight) and carefully restoring it.〔
Enthusiasts feel that the spacious electrical and mechanical designs of boat anchor radios are more easily worked on than the miniaturized layouts of modern Japanese gear. Fixing a modern transceiver often involves nothing more than a VLSI chip replacement. Vintage amateur radio devotees enjoy the more primitive experience that boat anchor radios offer, calling it "real radio". Enthusiasts claim that boat anchors sound better than modern equipment, saying that the tube audio from vintage gear is "warmer" and more aesthetically pleasing.〔(Boatanchors FAQ )〕 Some hobbyists see vintage radio operation as a valuable asset to help preserve the history and heritage of radio for future generations, and may assist in the restoration and operation of vintage radio equipment for historical exhibits, museums and museum ships.
