The All-in-One Swan Cygnet 260 and 270 Transceivers

摘要

Swan Electronics put out a popular line of SSB/CW transceivers in 1968, starting with the Cygnet 260. This minimalist radio was supplied with a 117 V ac power line and a suitable antenna. All you needed to get on SSB or CW was a telegraph key. A couple years later, Swan put out the Cygnet 270. The Cygnets were a new concept in ham radio transceivers in that they didn't need many accessories to form a complete station. They came on-air ready with a speaker, power supply, and, in some cases, a microphone.
