Work on my loop continues and hopefully it will be rotatable today or tomorrow. When I can steer the fool thing, I'll be able to get a better idea of direction and will report back.
My loop nulls are currently at about 50/230 degrees. With that in mind, I can't see it being NPG. But then I've been wrong before!!

Larry,

That's the signal I reported on the lowfer mailing list at 
http://mailman.qth.net/. Sounds like it may be very close to you, which 
is why it messes up 136 kHz WSPR. Maybe it's in WA instead of NPG in 
Dixon, CA. NLK has been QRT on it's normal frequency of 24.8 kHz. 
Perhaps it's now transmitting on 135.95 kHz?

I assume Laurence has been hearing it too even though he mentioned 135.6 
kHz. His heading is more consistent with CA than WA.

Using grid squares as follows: K3SIW=EN52ta, WH2XGP=DN07dg, KL7L=BP51ip, 
NPG=CM98ci, and NLK=CN98ae
(these may be a bit in error, but hopefully not by much)
I calculate distance/headings to be:

K3SIW to NPG=1774.8 mi at 273 deg
K3SIW to NLK=1682 mi at 296.3 deg

WH2XGP to NPG=624.5 mi at 190.4 deg
WH2XGP to NLK=122.5 mi at 302 deg

KL7L to NPG=1991.4 mi at 131.2 deg
KL7L to NLK=1413.9 mi at 118.6 deg

My loop nulls at about 0 and 180 deg are more in line with NPG being the 
source than NLK, as is Laurence's beam heading. However, the tremendous 
signal strength at WH2XGP favors NLK being the source. If the source 
continues transmitting headings from a few others would be helpful.
