elevator noise?/sheilding tricks?
The new elevator that was installed in my building here at the university,
puts out a large amount of noise on the AM broadcast band every time it
moves. I believe they are doing some sort of phase control on the motor with
little filtering.

In other words, you won't really know till the new system is
actually installed. That means a 50/50 chance for or against.
'Doc
thanks all, that responded
guess i'll have to wait and see,
i wouldn't mind doing a survey however i'd have no way to really know in
the residential area i live which building have electroic elevator
controllers or not , can't tell from outside and can't really poke
around
OK i guess a better question might have been:
so if the controllers give off bad rf
what is the best way to 'shield' those boxes so they won't bother my
antennas outside the room?
presume that i can ground the cabinents myself if they are not already .
thanks
