Hello Bob,
That sounds very interesting.
Any chance you can let us know some construction details and/or show us a
picture ?

I was also able to successfully receive SAQ with a homebrew
electro-mechanical receiver. As far as I know, the Alexanderson
alternator at SAQ is currently the only operating radio station with
an electro-mechanical transmitter that does not rely on valves or
semiconductors. For some time I thought it would be fun to make a
VLF receiver based on similar principles, also without any valves
or semiconductors, to receive the SAQ broadcasts. At first, I
thought this would involve some difficult mechanical engineering,
but somewhat suprisingly I was eventually able to make such a
receiver using parts from the junk box.
outstanding Jim !!!
this only goes to show that LF can be a tinkerers
play ground
