CI-V拆腾了代码民工两夜，
解决了原来像Array Solution等Band master被动跟随模式。
即Array的Band master连接电台后，一定要旋转一下大飞轮或者切换波段后
它的译码器才能获取当前波段信息。
这点Array Solution的用户手册上写的非常含蓄
For this:
When the Bandmaster IV is connected to an ICOM radio via a CI-V connection it replaces the
functions of an ICOM CT-17 since the Bandmaster IV contains all the required interface circuitry.
The Bandmaster IV then monitors all CI-V data from the radio for frequency or band changes
and selects the appropriate band. The Bandmaster IV can be used autonomously without any
computer attached. In this case, the radio still sends out commands indicating the frequency
whenever you turn the VFO knob or change bands.
而民工设计的是主动问询方式，即开了ICOM电台后，即使不旋转DIAL，或者波段切换
MCU依然可以获得最新的波段信息。
MCU没事就问一下，你现在QRG在何处。
