Willis,
Based on your experience, I scanned around and found this signal seemed to spread from 1392 up to 1566, with strong beeps on 1392.5 and 1458.5, the rest of the range had vestiges of the signal sounding more like a buzz or hiss, rather than a crisp tone.
Chances are, whatever this thing is, the primary component does not exist on the BCB, but appears there as an image of some sort. Since it is spread out, that may be the nature of the primary signal, some sort of spread spectrum transmission, the nature of which would require capturing that broad range to even see in its entirety.
For anyone who would like to see or hear this signal, I have uploaded two files which can be accessed as:
An interesting weekend diversion. Amazing the things you can hear when you listen between the intended signals.

Curt-
Have heard the same thing, at varis times, on 1400, 1410, 1420, 1440, 1450,
1460, 1470 and 1480.
Most times it sounds like CW sent with a bad fist.
Same thing has been heard on 1020, 1040, 1060 and 1080. All freqs at the
same time in parallel with each other.
Never real strong, usually about an S-6.
Curt, have you ever listen up into short wave bands when you here these
noises in AM BCB band? Their also up in the 49, 31, 25 meter bands, as well
as inbetween these bands, at the various time. Reminds me of the russin
woodpecker in the 70's.

This beeping continues. I am tuning it best now in CW mode, 1458.55kHz,
300Hz filter, 0Hz Passband offset.
The signal is weak but there is almost no interference, so it is easy to
hear once you find it. No idea how far it may be getting out, and
absolutely no idea what it might be, in the middle of the broadcast band as
it is.
