It could be that the broadband noise is local and the STANAG signal at
4286.3 kHz is strong enough to poke through the broadband noise and they
are not related at all.

Yep, heard in Portland on 4386 kHz about S3 less than 4 kHz wide!

As other have said STANAG is very common on HF. I have used SIGMIRA
software in the past to decode it.
I hear the signal on 4286 khz very loud here at almost any time, even now
(almost midday) it is strong so I'd suspect the signal would come from CFS
transmitters near Matsqui, BC. I do not know this for a fact so don't turn
it into one.
I do know that the signal observed here is less than 4 khz wide and if it
was truly as wide as you claim (over 3 mhz), that would be a serious issue
and would be widely reported by the many amateurs in the PNW.

I looked around your area (satellite) and see no military complex for
miles around. I suppose it could be a remote transmitter, but I'd have to
ask why Moscow Idaho?
At that signal strength I would expect the interference to be very > close
to your location. Unless it is some sort of high power military remote
transmitter, then others would surely hear it too. Is it on 24/7 or just
certain times? Maybe you should log the times it's on then correlate with
times other commercial establishments are occupied. If you have a portable
receiver that tunes that freq, take it for a ride out of town, park and see
if you hear it.
