Electronics

[Terry]

Grey area. I would have trouble referring to them as electronics because no active devices (triodes, transistors, possibly thermionic diodes, possibly crystals) were involved.

So you wouldn't classify the coherer as an active device, then? I know I'm jumping from transmitter to receiver here but the two do go hand in hand.

Also, the Titanic was equipped with a thermionic diode detector, although I think the traditional and proven coherer was also installed.

Following your rationale, the transmitter was electric but the receiver was electronic - but only if the valve detector was being used ...
