[Elecraft] OT-old vs. new 6L6 to K3

[John Ragle]

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.
