In this case... around 9 am or so, when the neighbor's wife is home, 
my noise shows up and stays on until she goes out, usually later in 
the early afternoon. It's rarely there when just her husband is home. 
(And no, I'm not a pervert, watching all my neighbor's wives, 
etc.  hi hi). When the noise goes away, I can shortly expect her to 
leave the house as she has apparently turned off the offending 
appliance. Similarly, the noise is gone when both she and hubby go 
out for dinner (or whatever people do when they go out between around 
5 pm and 9 pm) but soon appears when they get home shortly after 9, 
then stays on until they go to bed or fall asleep or whatever at 
around 1 am (or even later, some nites). (Fortunately, they 
apparently turn the offending appliance off late at night instead of 
leaving it on all night, like my ex-XYL used to do).

So I deduce this noise fits the usage pattern of, most likely, some 
sort of TV, most likely onna those plasma sets. I don't have a TV 
(nor cable TV service) so I have nothing to compare against. I 
suppose it could also be a computer monitor but it seems to fit the 
pattern of a TV better, I think.

That works very well with my 991A, too... but the problem is when 
someone like W6P?, W7S?, N0R?, K0R?, etc. with multi-kWs and 
multi-elements drops in on the frequency and starts ragchewing the 
same DX I'm trying to pull outta the noise: then my ears get blasted. 
It's almost like using an old HRO receiver without the AVC for 
Sweepstakes... your ears will ring for days afterward and everyone 
will have to yell at you and repeat everything a few times.
