Ya, but....
3Mcs - 30Mcs == HF
300Kcs - 3Mcs == MF
30Kcs - 300Kcs == LF
3Kcs - 30Kcs == VLF
300cs - 3Kcs == ? VVLF
30cs - 300cs == ? VVVLF
3cs - 30cs == ? VVVVLF
0.3cs - 3cs == ? VVVVVLF

But, at 1 cycle-per-second, I suppose one could employ
some sort of zero-crossing amplitude-step modulation.
It would take a month or two to transmit a moderate-sized jpeg.
HI!HI!
