The 6L6 keyed oscillator shown in the Flickr page is certainly a lovingly-crafted piece of artwork, but I am a bit skeptical about the implication that a techno-adept ham of the late '30's would have been pleased by the chirp. After all, the 6L6 first appeared in 1936, and by then the 'x' and 'c' of the RST/x/c reporting scheme was probably already in use. Keying an oscillator working directly into an antenna was understood to be a poor idea. The MOPA idea was around long before the 6L6. There is a QST article in 1934 illustrating the general idea of a 2-stage transmitter, and the idea was known long before that.
