//1.0 , 04/16/2007, lilin, RDA
//1.1 , 06/01/2007, lilin, RDA, not change this header, only to sync with c program version
//1.2 , 06/22/2007, lilin, RDA, add stopseek and filter false station
//1.3 , 07/29/2007, lilin, RDA, move filter false station function into FmSeek, remove FmSearch, FmWaitSTC1_stopseek
//1.4 , 08/13/2007, lilin, RDA, use seek_singlestep function if want to display incremetal frequency station
//1.5 , 08/27/2007, lilin, RDA, adjust seek time to minimize, use delay 100ms to replace polling STC
