Experts, please provide guidance on how to use the RS-456M tuner with the IC-705.

最近鱼塘里蹲了一个成色不错的瑞雪，想配合IC-705作为QRP天线使用，但是接电后无法调谐，是否是需要做一根控制线？求大佬们指导。

BH4GTG Yesterday, I spoke with someone from Beijing called Su Ge, and he said that all it takes is to add an external control button.

Regarding power level 705, it's uncertain whether it can trigger the tuning function.

It should work fine. It can be powered by either a 5W or 10W power supply using DX10.

The 705 has too little power; I'll build my own amplifier instead.

I wanted to get a 705, but I couldn't.

I actually tested the 705 with its own AH4, and I couldn't even get it to move. Neither could I get the 9350 (belonging to Cotton) to move.

I've already reduced the power to QRP levels. How much power can I still transmit with the current settings?

BI4MIG For full-segment transmission
