The way SCANCAT deals with the Mr. Scanner Database is illustrated in detail on our Video tutorial #4.  This method does not use the MSPSFSHARP.EXE search engine, but uses "out built in" search - which also places the search results directly into Scancat's database for a lot easier time of getting them into the radio <G>
        The Tutorials are located at
