FASST 2.4 GHz are the same in all countries?
All Futaba FASST are the same in all countries around the world?
I mean, if I buy a Futaba 10C in China and a receiver in U.S., they will work?
I have such a doubt because my friend told me that they work with different frequencies. Is it true?

Thanks

The frequencies should be the same. It's the power output may be different.

Do you know if there is any difference in the power output of the radios sold in Hong Kong and USA?

I think the Rx's are the same, the radios and modules might be different. I have R606FS, R617FS and R608FS all from the USA working fine over here in OZ with my 14MZ. I know that the 2.4 module for the 14MZ is region specific because a friend tried it and it wouldn't work.

If you buy the 10C in China and the Rx in the USA they will work.

The Rx’s are passive they don’t transmit.

The 10C has a France setting. This setting restricts the frequency range when the 10C is to be used in France. The output power of the 10C TM-10 RF module is 48mW.

Spektrum/JR output power is 128mW. Spektrum/JR is not permitted for use in France because DSSS maximum power permitted in France is if I remember correctly 10mW, which is too low a power level for reliable RC aircraft control.

Futaba chose to use FHSS primarily for the reason that it is more universally world wide accepted with fewer restrictions.

The radios 12FG, 12Z and 14MZ are region coded to the TM-14 RF module.

We need
someone to test the output of all the area modules, you cannot
get a straight answer from most people who claim to be in the know.

The Futaba 2.4GHz 6EX transmits 100mW of power worldwide.

As far as the US is concerned, take a look at the FCC report (this is the US governing body concerning radio emissions etc.),

https://gullfoss2.fcc.gov/prod/oet/...tive_or_pdf=pdf

Page 42 shows a "peak output power" of 18.26dBm, i.e. 67mW, and when you then take into account the gain of the antenna you'll end up at 100mW.

In the UK I know for a fact that Futaba transmit at 100mW, most of Europe is the same, although in France they have some additional restrictions on the maximum power transmitted at the top end of the 2.4GHz band.

I'm not 100% sure about the 10 although I would be very surprised if it was different. For the US power levels you can probably also look these up on the FCCs web site... In the UK the 10 series transmits 100mW of power.

Hope this helps.

Basically we can think that we have two levels of transmission. One to France and another for the rest of the world?

Thank you

OK, here is French situation for those that are interested.

Indoors: (No restrictions)
Frequency Range (MHz): 2400-2483.5
Power (EIRP): 100 mW (20 dBm)

Outdoors: (band is split into two regions)

#1
Frequency Range (MHz): 2400-2454
Power (EIRP): 100 mW (20 dBm)

#2
Outdoors #2:
Frequency Range (MHz): 2454-2483.5
Power (EIRP): 10 mW (10 dBm)

It's a bit unexpected as you'll see from the above ranges and numbers that for indoor use 100mW is OK, however for outdoor use the last 29.5 MHz of the band is restricted to 10mW!

My source for all of this is:

http://www.espectre.arcep.fr:8080/i...=238&id_zone=59

The phrase "l'extérieur des bâtiments dans la bande 2454 - 2483,5 MHz" translates to:

Outdoors in the band 2454 - 2483.5 MHz
