FT-857，FT-897，FT-817的电路是一样的吗？ [复制链接]

呼号ad6a说： i have owned my new ft-857 for a couple of days now. it's much as i thought it was going to be - another great rig from yaesu. basically, a small mobile version of the ft-897. i took some time to pore over the schematics (i own an ft-897 also) - the ft-897 and ft-857 are virtually identical. fyi, the ft-817 is almost exactly the same circuit too - but with a much smaller pa（power amplifier).


呼号ad6a说：ft-897和ft-857实际是一样的，ft-817几乎也是同样的电路，只是功放小。

857和897是一样的我们都知道了，但817真的是除了功放外就是和857是一样的吗？

哪位研究过三者的电路图？

一鱼三吃。

应该如此，至少，857和897的电路是非常相似的。

857、897功放的推动基本就是817的功放。

这个系列的我只有817，但使用朋友们的857/897的时候操作很快就可以上手了，操作软件差不多。
