Possibly other sources as well.  I'm a member of the crew that activates 
Alpine County [N6A] for the Cal QSO Party in early Oct.  Our long time 
camp was a couple of km off the highway at the summit of Monitor Pass, 
no power lines for miles, and our base noise level was S0.  Station was 
on 10m CW, and suddenly the noise went to S5 and looked exactly like the 
screen shot on the band scope, slowly drifting up and then down.

Checking 15 and 20, the noise was barely perceptible.  Turned out Larry 
had just plugged in his electric shaver to charge it, and the cord was 
close to 8 ft long. :-)
