Behold, Doug Smith W9WI signaled from keyed 4-1000A filament:


I'm not sure whether the 5,950 kHz figure in 73.701 has been amended to
accomodate the tropical-band stations like WWCR, or if WWCR etc. has a
waiver to allow use of the lower frequency.)


It would make sense, especially in the west where the mountainous
regions
would benefit from the larger groundwave coverage of the upper MW/lower
SW
bands.

There's not much useful groundwave coverage much above the MW band - the
signals are "skipping" but at such low frequencies, the "skip zone"
disappears..

But that's really beyond the point. Yes, from a technical standpoint
the lower frequencies are useful for covering areas relatively close to
the transmitter. I would think, however, that you've got to be able to
show *some* useful coverage outside the U.S. before you can get a
frequency approved. Or maybe they ignore 73.788? (not impossible)

Remember, the prohibition of domestic SW came from the desire to protect the
US clear channels in the early 30's. The AM 50 kw stations were supposed to
offer extensive regional coverage, and SW was prohibited from competing with
them. (It had nothing to do with the war as far as I have researched)

Since clear channels essential don't exist, maybe the FCC does not care.
