My neighbour, Rob VK2ZNZ called on 3.595MHz just after the WIA broadcast this morning and invited me over to "see a thing of great beauty". He was not wrong.
I can't find many mentions of the Splitdorf radios, but it looks like it's missing a big wooden case.
Certainly a thing of beauty. My impression is that it's been restored at some point.
A very simple circuit.
They sure have a lot of patents!
It is so simple it would have to be a TRF or perhaps regen radio. Anyone know anything about these radios?
