Mystery Boatanchor Followup (and a little 'Oops...')

摘要

Our November 2010 issue carried an article by Dennis Lazar, W4DNN, entitled "Mystery Boat-anchors, War Stories, and the Viet Nam QRP Crow," in which the "mystery boat-anchor" was a Heathkit DX-40 transmitter with an additional inscription on it of "Sperry R&D 5100." Author W4DNN, who picked up the rig at a flea market, wondered about its history. Several readers caught a couple of typos in model numbers (but added to the confusion in the process), and one was able to shed at least a little light on the more recent history of the DX-40 in question.
