Johnny, SM7UCZ has made a top-notch job of his new Sputnik transmitter!
The schematic diagram of his circuit layout, plus more photos may be found here.
Among the many interesting tube and transistor QRP projects to be seen on Johnny's web site is the story of a hand-transcribed copy of Frank C. Jone's, 1938 edition of, The Radio Handbook (please click here).
OM, Sven Bernholm, SM3RN (1888 - 1963), laboriously translated this work into Swedish whilst standing radio watch in the years 1944 to 1945. Sven beautifully hand-copied over 400 pages of text, schematics, drawings, graphs and tables. I'm surprised that he didn't illuminate the pages in the fashion of medieval monks! His little side-notes are especially interesting; for example
5/5/1945: "Denmark and the Netherlands, free!"
7/5/1945: "Germany surrendered; Norway free!"
12/4/1945 "Roosvelt dead - Allies 6 miles from Berlin!"
Johnny recreated a Frank Jones-type "push-pull" transmitter similar to the one appearing in Sven's transcription (here).
There are several Parasets, a Hartley transmitter, a tube superregenerative receiver for the VHF BCB and a transmitter built to operate on 1.5Vdc (and less). The fine art of homebrew QRP is alive and well in this little corner of Sweden!
