Hi Myles,

Trust your instinct on this one = it's the elevator motor controls.

i still havn't figured out how many turns to make around my 2x2' X of
26ga wire insul, as i see i will really need a very directional
antenna to pinpoint

I'm not sure what to make of that. Just use a small SW receiver with
the whip pulled back into the set. Smaller the antenna, the closer
you have to get to the noise. The closer you are, the more obvious
the source.

seems very easy now to say what seems obvious but doing the actual
finding scientifically is harder then i thought due mostly to my
poor skills

Your skills got you to the source of the problem, the difficulty is
more your coming to terms with how to solve it. You aren't going to
get into the elevator control room to fix anything - even if you knew
what to do. Management isn't going to spend money to fix a problem
that doesn't bother them. Ask your neighbors if they have any TV
noise issues that just started - get allies. Think about it, if they
complained about your HF rig messing up American Idol and the building
super came down on you; then they could as easily demand he fix the
elevator for messing up American Idol too.

i think i have enough test gear but sorta not sure what do to
track the noise down , never really did that before as far as
specific professional methods and procedures

Time to look into the gear that does noise canceling. We get a number
of posts here from those who find relief from just your kind of
problem. All it takes is an outboard unit with its own very small
"sniffer" antenna (probably not any bigger than a short 3 foot whip
for your purposes). Twist a couple of controls and the noise plunges
to S3 or so. Maybe someone in the group who knows the vendors can
suggest something here.
