標題: Arduino控制RadioShack Pro-405 MB1501仿真源碼與實踐(寬頻接收機改造)
本人的Pro-405 寬頻接收機部分按鍵無效，顯示看不清楚，出差改了這個程序，29-54/87.3-107.9/137-174/380-512MHz 基本步進均為12.5kHz，可選50/100kHz,有W/NFM切換控制，未做波段控制。29-54可接電視高頻頭中頻，87.3-107.9可有可無，音質一般，380-512本地還能收到幾套模擬伴音，歡迎各位改進。
MB1501_Scanner.ino 副本(2)V0.1直接計算參數，副本采用遞加遞減，仿真長按F+，發送間隔均為111ms，主要取決于按鍵延時100ms。V0.2按鍵延時可變，仿真長按F+，發送間隔約為21ms。
Arduino無法直接輸入中文，有簡單英文說明，引用部分保留日文注釋。
Pro-405.xls為相關參數計算，其中380MHz 4F應為50，難道是WPS的問題？
