Good point, Bruce. It is something of an LF desert, largely due to the decades of unbearable clatter of megawatt pulsed LORAN-C transmissions centered at 100 kHz. Even though those are gone now, apart from occasional so-called eLORAN experiments, the allocation remains. There has apparently been little demand for new LF stations that are (a) almost by definition, expensive to build; and (n) could be subject to high-power adjacent channel QRM at any time. -John
