SWL in a downtown apartment...(curses!)
 

I recall reading about a device that would sample the outside
electrical racket and apply it 180 out of phase to the radio input in
order to reduce the interference. Perhaps someone in the group has
information on it.
In the meantime some of the osculators in the streets of Reno could
send you some signals.

I Live in an RF High environment ( NYC)

ANY info would be appreciated..

Blackouts do have a benefit here.. You can hear Shortwave ! ! !

The device is a Timewave ANC-4 Antenna Noise Canceller. It has
excellent reviews in eham. www.eham.net/reviews/detail/1138

MFJ makes one also. But keep this in mind- it is not magic. The principle is
that it picks up noise on a sense antenna. You match amplitude and invert
the phase of the noise and then add that to the signal+noise coming in from
your RX antenna. Theoretically the noise cancels itself.
This will NOT work with multiple noise sources as the amplitude and phase
will be different for each source. If you have one dominant noise source,
like an arcing power transformer, it may be worthwhile.
