这段时间测试,使用RF Mode #1 视频亮度明显降低,RF Mode #2 效果会好不少,缺点是 #2 没有OSD显示及信号锁定提醒。
rapidFIRE #1 mode pulls out all of the stops to eliminate multipathing, and repair the received analog video signal. It should be the preferred mode in which rapidFIRE is used.
In order to perform its magic, it requires an intimate knowledge of the video standards that it is repairing. Unfortunately the FPV world contains a few cameras and OSDs which violate various aspects of the PAL/NTSC spec. Of course, this being a rather new spec, we shouldn’t be surprised (that was a hint of sarcasm, the standard has been out since the early 1960s….).
rapidFIRE #2 mode was created to deal with the few cameras and OSDs which don’t like to follow these well established standards. It still dramatically reduces multi-pathing, and in most cases will be indistinguishable from rapidFIRE #1 mode.
At present, rapidFIRE #1 mode supports the rapidFIRE OSD overlay, but mode #2, and legacy mode do not support it.
