Regarding the picking up ticks on an AM car radio, I must not have been around at that time. As I recall, the magnifier's e-coil was resonant at just below 100 kHz., and with the tower structure directly connected and raised to the highest position this went down to about 37 kHz, which means an ordinary AM radio would be way off frequency even when set at the low end of the dial.

I remember getting ticks in AM radio from ignition systems in cars, when using "Real Copper" plug wires (but mush better spark), say a 4 cylinder engine, at 7000 RPM, each plug fires once every other rotation, that means the coil fires at 14000 times a min, this is also well below AM bands, but you can still hear a loud tick in the radio.
