Apparently you do NOT care but that radio is not legal in the USA unless it has FCC certification.
To my knowledge it does not !

BTW It is not a "full hopping system" as you state.
Like all the other systems with frequency 'hopping' it is a DSSS with frequency hopping (a hybrid) and was designed for Japan, though some are also in South Africa.

Hope you enjoy paying for the transport back to Japan should you ever find servicing necessary or advisable.

Unless you are headed to Japan and wish to use it there it is a foolish purchase.
BUT, as stated earlier apparently that does not bother you. Nor
does the fact that your AMA insurance would not apply either, check it out!

Even IF you are using only 72MHz modules servicing is still a problem.

Frame rate is 22ms. Total latency depends upon the Rx as well, if you are using the common meaning for latency. If you are using XJet's definition it would include the servos as well.

JR's 2.4 GHz features, including Rx design is controlled by Spektrum USA. That includes DSMJ which is also designed by Spektrum. Simply for the Japanese market.

As with "gray (black actually) market YS engines" -NO service or parts in the USA.

Onewasp, My decision to fly on DSM-J is because it is legal in the US. I have already asked and confirmed this.

Well then, you'll be able to furnish the rest of us, probably including Horizon/Spektrum, with the appropriate FCC ID numbers then.

I really tend to doubt that they exist but with the correct FCC ID numbers we all can find the approvals.

How about sharing it/them with us so that we all may see for ourselves.

The pertinent FCC numbers for the X9303 are :
FCC ID BRWDAMTX10;
IC: 6157 A-BRWDAMT

Those are also the numbers for the original DX7 introduced in 2006 so the RF sections have the same FCC numbers and are the same insofar as the FCC is concerned.
The DSMJ will have similar FCC numbers (but not the same) displayed on the Tx/module or it isn't legal in the USA.

I look forward to learning something new here.

Onewasp, I advise you to contact Horizon/Spektrum yourself for the information you seek.

I don't spend time feeding dead horses.
Thanks anyway.

Back to my original inquiry,

<o></o>

I’d like to confirm that the 11x Zero (DSM-J module version) has model <o></o>

Match and that it has the software for Servo Matching to eliminate using Match Boxes.<o></o>

<o></o>

I know that the DSX11 (DSM-J Dedicated) has both these Feautures.<o></o>

<o></o>

I’d also like to know if there are any latency numbers available, and if the module based version is considerably slower.<o></o>

<o></o>

When it comes to the software, what exactly is different between the two? <o></o>

<o></o>

At this time I still prefer module based TX’s for the flexibility that they offer, but these two features “Model Match” and “Servo Maatching” are important to me.

Thank You<o></o>

I translated a few pages from Japanese, I saw mention of a 10mw power limit on 2.4 GHZ in Japan.

Pitstop000, I advise you to contact Horizon/Spektrum yourself for the information you seek. They were the ones who supposedly told you it was legal in the US, I am unable to confirm this and I'm not looking anymore.

The module based system will not have Model Match as the module system is only processing standard PPM data.

That was my thought but I heard otherwise in relation to this particular system.

onewasp

I thought that too but remember that the11X uses the older module design rather than the new design created for the 12X.

Based upon occupation I'd have to give an edge to Slarty.

The information that I’m receiving is that as long as you are using the 11 channel module (DSM2/DSMJ JR Version) In the Zero it does have Model Match.

<o></o>

If you use one of the other modules ( FASST, Spektrum DM9, 72mhz,or any that are available that can be used in a JR 9303 then it uses the PPM for processing and no Model Match.) This is the information that I’ve gotten so far.

<o></o>

At this point I’ve decided on the module based TX, I’ll find out more when it arrives. . I’m done speculating.

slarty

Please keep us informed when you receive it and tested it for Model Match.

Strongly suggest that you read Greg Hahn's comments on page #142 of the August issue of
"Model Aviation". (AMA mag.)
It deals directly with the problem you are creating or at least supporting.

Your "I’m done speculating" has no bearing on the problem.

Turbotronic

I have both. There is no difference in the hardware, pcb's etc between the 2. The TX RF module has the same FCC ID and is legal as far as the FCC is concerned. The DSMJ has better software and is still DSSS hopping over a number of channels. Re-sync is done on a single DSSS channel making it very reliable and fast to relink.

Onewasp ,

<o></o>

My “I’m done speculating” [/b]statement pertains to the “Model Match” [/b]and “Servo Matching[/b]” features of these 2 particular radios.

I will not be baited to where you want to lead this to! You are wasting your breath with Me !

DSMJ 2.4 is Legal[/b] in the US!
