well japan is using DSM J ( for japan )
output
0.003w/mhz and 130ma i just received my module and not tested yet. i'm using jr 12x air model mode 1 on 40mhz
its suppose to be DSM3 and not 1 or 2
the 2.4 set also comes with more advance rd 1231 and all made in japan.
i hope it will work with my older 6000 / 7000 rx...

fuse Can you tell me is the module of dsmj can compatiable with ar6100 or ar7000?

dsmj is work with 9303/9XII and 12X only. It does not work with JR X2710, X2610. dsmj is compatible with Spektrum any styles of DSM2 receiver. It does not work with DSM receiver. JR claims it is faster respond than Spexxxx 2.4Ghz module.
Is dsmj support 2048 revolution? pcm 12x with dsmj and dsm 12x with dsm/dsm2
which is faster?or the same?

I want to know if DSMJ has better failsafe support.

JR Japan said DSMJ is advanced DSM2. So I think it's better than DSM2. But I dont't know whether it's true or not.

stupid,
Where did you get your DSMJ module from? Price? I also have the 12X on 40mhz, and want to get the 2.4 module.
Thanks, Keith

Japan has them. Ishimokeli to name one and also Champ RC. The module set 2.4 ghz/Rd1231 is about 35000 yen and the 2.4/with RD931 is about 32000 yen.
From what I have found. It's a module upgrade to the 12X synth radio to turn it into 2.4 ghz. It apparently signal hops like Futaba's system. They told me is is the same output as the USA of 100mw. Just plug it into the tx like the spektrum modules. I have been looking at these instead of the USA version but can't see the need to use 72 mhz if i have 2.4 so prefer the tidier USA version where the 2.4 aerial is integrated into the radio instead of a module plugged into the back. From what i understand it's as quick as an integrated system just like the later model futaba radios. Anything that has a digital signal prior to the 2.4 ghz module doesn't latency issues like when 2.4 GHZ first came out with when modules to plug into the back of your radio first arrived.
Therefore this radio is like the USA version 12x MV which can use 2.4 or 72 mhz (or 40 mhz) as long as you have the 2.4 and standard module except that the 2.4 is DSM J. I am still trying to find out how it sends the signal but it seems it may be like the faast system and hop frequencies. Getting this information seems semi impossible and I dont speak Japanese.
What i can tell you is that Ishimokei said that the 12x 2.4 only works with the RD 1231 and RD 931 receivers only sold in japan and will not work with the RD1221 and RD921 sold in the USA.
The question is why did Japan Radio bring out their own 2.4 implementation and own receivers operating on 100mw the same as the USA version even though they produce the JR equipment for the USA on the same power. Why not sell the 12x MV and the RD 1221 and Rd921 in japan as well??? Does this mean the Japanese think there is a better system for 2.4 than spektrums system? Does this mean they think futaba was right? I'd like to know Anyone???

Perhaps the Japanese requirements simply require FH. As I understand it, 2.4 GHz use for RC in Japan was very recently approved.

They probably had a choice of 10 mW with standard US Spektrum or 100 mW with FHSS. It may be essentially identical except that instead of 2 freq. it uses the number that the Japanese definition of FHSS requires. This would just be new s/w. This would still be an improvement over the US version. This may also be marketed in the EU which has the same problem with their regulations.
