I would have to use an analizer to measure RMS power versus peak power. dont have access anymore to it. I retired last week.

When you plot signal output, its usually measured in RMS "root mean square" or about 70 percent peak, and the area is then calculated to determine power, versus peak power.

kinda like the stereo wars where amps say peak power 200 watts, 50 watts RMS...

Anyway, Im not sure about his with spektrum, so I will stop there as there are alot of you guys smarter than me on it. I just have a basic practical working knowledge of spektrum only.

I do know this though. we worked with a 2.4 video transmitter, and it locked the fasst system out, and as long as you turn it on before the DX7 transmitter it worked fine. but that is a specific case.

my best to all
