If it does turn out, in this thread, that the "mundane rules over the exotic" - as is usually the case admittedly ... and that this particular anomaly is related to what could be - not only an ultra-efficient receiver for RF in the extended band - but also a kind of self-powered broadcaster, then ....
The side note of interest goes back to Ron's historical observation that the early radio antennas often consisted of a wound bar of barium ferrite.
My favorite 'Nam-era Pioneer stereo receiver-amp (and home-heating device <g>) had one of these, but soon after they were abandoned ...anyway ... this cause-and-effect scenario could be the very reason that 1.6 Mhz was carefully sandwiched-away and into broadcasting obscurity by the FCC in the early days of radio.
That is to say: Maybe the antenna itself in those days had the potential to add so much self-generated "static" to the narrow RF spectrum around 1.6 MHz that it had been pragmatically eliminated early-on as too undesirable a range for the technology of the day.
