Occasionally when tuning through the short-wave bands, I'll find a carrier
signal that pegs my s-meter but there is absolute dead silence in terms of
voice, code, etc. Sometimes it lasts for hours, sometimes it goes away
rather quickly.


Just a transmitter that's on.

Or a TV set or other video gear (3.5785 MHz, 7.159 MHz, etc). Or any
microprocessor controled home appliance. These are often on 1 1MHz
multiples, or on TV color burst frequencies, (3.5975 MHz or multiples
for US), because the resonators/crystals are cheap. Or computer gear.
Or your neighbor's pickup truck's engine controller. Or an internal spur
in your receiver.

7159 is a problem for me, as 7160 is the BBC frequency for 16:00-18:00
for the North Pacific area.
