[AMRadio] Bad Static Problem

Update on static problem:

Yesterday, I tried both a 6 foot wire and my Ringo Ranger 2-meter antenna
(just the center pin of the PL-259), 
and the static is still there, but not as strong as with the hf vertical.
I thought at first that I tracked it down, because I found that the dimmer
switches for the recessed lighting in the 
kitchen were making all kind of noise at the very low frequencies (peaked up
at 170 kHz).
After shutting the lights off, I found that that noise went away, but the
noise on all the lower hf ham bands was still there just as strong.
It doesn't have any sharp peaks or anything, but there are a lot of places
where it does kind of peak up, although it is very broad. 
The freqs where it seems to peak are (in MHz): 2.4, 2.7, 3.37, 3.55, 3.9,
4.2, 5.0, 6.2, 6.6, 7.2, 8.0, and 8.7. Above that, it starts to roll off
quite a bit.
The peaks might have something to do with the resonance of the antenna, but
I'm not sure. I was using the hf vertical when I measured them.
Any more thoughts? I'm thinking probably power lines, but maybe I should try
a battery-operated radio and turn off the power to the whole house before I
come to that conclusion.

Last night I had HIGH static on both my HF receivers. And I have been having
a problem with static discharge.

But it has not been snowing in Seattle. They wish it was.
