健伍 TH-D74E扩频
On the main radio board, remove R761. I just used a fine point soldering iron and it came off easily.
在主板上 拆除R761电阻 需要一个细头烙铁
Reassemble the radio, reset it and you’re good to go. Here is the TX range after the mod:
136-174 Mhz
216-235 Mhz
410-470 Mhz.
I have not noticed any ill side effects from performing this mod.
