Win2Tanker,

RadioShack PRO-84 Scanner Radio - 200 Channelshttp://www.radioshack.com/product/index.jsp?productId=2180625
This is a Small Handheld Scanner with a relatively short
Antenna connected to the Radio via a BNC Connector.

MOST LIKELY - When the Scanner's Backlight is used :
The Scanner uses more Power; and this Reduces the RF
Gain of the Scanner; resulting in Less RF Signal being
heard along; with more internal Noise from the Radio.

Usually the simple Answer is a Bigger Antenna.

Thank you for your help. The thing is that I have a large old CB
antenna(has 2 large pieces of copper wire extenting a few feet in
opposite directions). I sometimes have it connected to and for some
reason the interference happens more often with that antenna than when
I use the small antenna that came with the unit. Also the
interference tends to go away when I turn the backlight on when using
the old CB antenna. LOL maybe my scanner is just cursed.
