扩频方法:

With all control knobs facing towards you, Remove top cover, Notice Front Left corner is the processor with a crystal mounted on top. 打开顶盖,注意左前角的处理器附近


Extreme left of the radio you will see a row of pads, All empty except for a diode to the front and one to the back, Notice 7 or 8 spots for diodes, But only 2 installed.
在左侧边缘有一排焊点,只焊了2个二极管。


REMOVE the FRONT diode closest to the head of the radio with a small soldering iron or tool.
移去前面(最靠近电台头部的地方)一个二极管


Turn the radio back on it will automaticaly reset.. See photo‘s of the FT-8800 and FT-8900XXX Mods, location of this diode is the same.
重新打开电源,机器会自动复位。FT-8800/FT-8900的TX修改位置相同
