Object Oriented Scanners Overload Issues
These scanners have a very sensitive front end. In urban and semi urban environments, or those living in or near areas with numerous radio towers, this causes a serious problem with overloading and desense. The cause is likely to be insufficient filtering in the front end, allowing high power FM stations, pagers and so forth to blast into the amplifier (more information on this is needed).
If you are putting an outside antenna (or even something indoors of any size) on these scanners, it's very likely that you will run into this issue. While you can run the attenuator on the frequencies where you have trouble, a far better approach is to add filtering. When adding a filter to your scanner, make the connection as short as possible to minimize the possibility of stray pickup. The following distributors/manufacturers of filters have been mentioned on RR in the past; please add any others that are found to be helpful.
