What continues to puzzle me is the simplicity of the design, for example, no gain control in the receiver, and
the cathode modulation point, which would only work with the 1.5 volt battery tubes installed. And the
crudity of the schematic drawing, with the tube symbols looking like something from the 1920s. The whole
thing looks quite home – brew. That the government post – WW2 built an AC power supply for it, and whose
style is clearly much more modern, is just plain weird. If the military needed a training radio, there were much
better sets already being surplused !
My thinking is that it was designed for some clandestine purpose ( not a great leap of imagination ) but that
it quickly became clear that it was too ham – hobbyist, took too much ham radio type practical knowledge, for
the newly minted radio operators. Like that loop of wire with a light bulb, for tune – up, or a piece of plastic
cloth to put over the key to keep you from getting a shock. Like Mickey Mouse labs engineering. Altho the
mechanical construction is well done.
No one has ever seen a handcrank generator for this set. This is another piece of evidence that ( so far )
persuades me the set was never actually used in WW2.
