标题: Arduino控制RadioShack Pro-405 MB1501仿真源码与实践(宽频接收机改造)
本人的Pro-405 宽频接收机部分按键无效，显示看不清楚，出差改了这个程序，29-54/87.3-107.9/137-174/380-512MHz 基本步进均为12.5kHz，可选50/100kHz,有W/NFM切换控制，未做波段控制。29-54可接电视高频头中频，87.3-107.9可有可无，音质一般，380-512本地还能收到几套模拟伴音，欢迎各位改进。
MB1501_Scanner.ino 副本(2)V0.1直接计算参数，副本采用递加递减，仿真长按F+，发送间隔均为111ms，主要取决于按键延时100ms。V0.2按键延时可变，仿真长按F+，发送间隔约为21ms。
Arduino无法直接输入中文，有简单英文说明，引用部分保留日文注释。
Pro-405.xls为相关参数计算，其中380MHz 4F应为50，难道是WPS的问题？
