资料说，经扩频后
tx:136－172； 400－470
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-8900r tx 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。
请各位指点，是有效吗?
