Hi Doug:
Can you power your WWVB receiver from batteries and shut down your house AC?
That way it's not something inside your house.

Thanks to all who responded with suggestions and comments. Here is the latest...
At great effort, I moved the loop-stick antenna and preamp, now mounted on a
pole, from the rear of the house to a midpoint of the house toward the front.
The old position had the antenna about 10 feet off the ground. The new position
now allows me to rotate the antenna, and it is 21 feet off the ground. Just my
luck, that could hardly have been a worse move. Now the offending carrier is
much, much stronger, and completely swamps poor little WWVB. Also, the
offending illegal transmitter does not null with rotation of the loop-stick
antenna as WWVB does. This to me means the generator is local to the antenna.
My neighbor has a DishTV antenna and down-converter across the way from my WWVB
antenna which stood a good chance of having a SMPS in it. I leaned my antenna
and pole over the fence toward the dish, and the carrier immediately saturated
my preamp. So, the next move is get my WWVB antenna and preamp centered on my
lot, as far from illegal transmitters I can't control as p!
ossible.
The analog multipliers for my Costas loop arrived today, so I'm super-anxious
to get a decent signal...

Subject: [time-nuts] strange carrier
Importance: Low
I'm working on my WWVB BPSK receiver and am receiving a carrier, 10 dB stronger
than WWVB in Sunnyvale, California, quite stable, on the air 24/7 at a
frequency of 59.99240 kHz. I have researched on Internet what it might be, with
no results. I have turned off all switch mode power supplies at my location
with no effect. The carrier is so stable that it seems like it must be
something intentionally generated. I have not tried nulling it out with my
directional antenna yet.
Anyone have a clue as to what I might be receiving?
Thanks,
