Thanks Larry/Garry - I wandered out in the woods and checked the rotator and headings and surprised myself that it was still within a degree or two since install - given this rotator is some 15 years old, ex radio shack and has no "feedback" its doing quite well.
I checked the bearing again and for direction I came up again with around 135 degT - In fact I think I was getting a little skew and was more like 138 but some odd things happen with all these mountains (with new snow atops I might hasten to add) - and Ill double check the freq again tonight as Im pretty jet lagged and prone to mistakes for a day or so :-)
It did go off at 1400Z for 3 minutes before fading into the noise at sun up. It was a strong signal even with the phasing and very rapid fades/attenuation so it must be a pain at Larrys -
We used to hear this signal/station quite often when I lived in Okie driving to work from memory

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.
