There are 2 pictures showing the signal levels, which of the pictures will display the signal level to allow the drone to fly further?
1.


2.

The first foto is CE mode, the second foto is FCC mode. In FCC mode the 1KM mark is above the 90dbm line. So with picture 2 it will fly further.

Looks like the first photo is in CE mode and the second is FCC, so I bet a beer for the second one which in theory has a further range.

Bingo!

how do you set FCC on EU models?

This is a well illustrated example of why asking for technical help on this forum is going to mislead you. The graphs are a a band-scan, of a section of the 2.4Ghz band showing the signals that the RC device can receive at the time. The first graph shows a lower amplitude of signal than the second, therefore the range of the device would be better in the first example than the second. Yet all those who are clueless have selected example 2.....

+1 for an answer to that question too.

Don't expect this to be answered here. We don't want this ability to be patched out or this thread deleted.

Actually they should be very similar a, #1 -97.5dB , #2 -97.8dB

Yes, and I don't understand why this small difference would outperform pic #2 (FCC mode, ~400mW transmission power) over pic #1 (CE mode, ~100mW) as posted by Geebax in post #6. All other values are pretty much the same.

I still believe picture #2 would let the drone fly further. But I'm open to be taught of course.

Why do people think it is CE & FCC?

Since you are so "smart" and the majority of us are "clueless" maybe you can explain us how a 20dB 100mW sinal will give better range than a 26dB 400mW one. Because i have no doubt second picture is FCC mode (26dB 400mW)

Because in the first picture the 1km mark on the right is aligned with the 90dBm mark on the left axis. This indicates the transmitter works in CE mode. In the second picture the 1km mark is aligned with about 87dBm on the left axis. This indicates that the FCC mode is active.

Edit: When we are in Germany the transmission chart looks like in the first picture (CE). When we take the drone to Florida it looks like in picture two (FCC). Although we have a Mavic 2 with the DJI Go 4 app, the transmission graphs look almost identical.

I was not aware of that, as I only run FCC mode.

So, this settings area could reveal the range of flight before take-off?
Interesting to follow on next flights…

The indicated signal peaks are NOT those is use by the controller he is using, They are signals from other sources in the vicinity.

So FloridaNext has it right

I guess there are some legal issues, harder (or easier) to prove, regarding power transmission.

I know this is a very old thread but i was looking for answers regarding how to interpret what i see.

so my interpretation on what i see.

1KM text placement shows what mode the controller is in
1KM aligned with -90DB line=CE mode
1KM above -90DB line=FCC mode

now according to Geebax the graphics does not represend the signal strength of the drone/controller, it shows the signal strenght of surrounding signals(wifi routers/disturbance)
So if this is the case  the graphics shown should be labeled as signal/noise ratio
eg when this ratio is high(-120) you have a clear band to use
this also makes sense because a very strong signal(like a wifi router) will display somnething like -40db(very good signal)
with this controller you see -97,5db which is a good signal/noise ratio

can anybody confirm this just to be sure.

You mean below the 1km line? yes, this is FCC mode, if the line is inline with 1km then its FCC
Normally the db changes too, around i think -88db, it did with my old Mini 2...

All you really need to worry about is, CE is in line with the 1km, FCC is below the 1km line, the power difference it quite a bit and even more so in 5.8g,  i.e. in FCC 5.8 and 2.4 have the same power @ 26dbm, whereas in CE 2.4 is 20dbm and 5.8 is even worse at 14dbm
