DMSS (Dual Modulation Spectrum System)
Looks like it is targeting the weakness of DMSJ.
Comparison with DSM2 shall be interesting

Wish I could read Japanese, Google can't help here as the text is all within the images.

DMSS looks like regular frequency hopping DSSS? i.e. FASST/DSMJ

Perhaps it's two adjacent spread components, that are then hopped over the available band? Or just FASST/DSMJ with wider components?

Anyone know? Can anyone translate the Japanese text?

Old news.
DSM2, DSM (Patented BTW) is going nowhere but onward and upward .

Read the attached and verified letter from JR.


To Our Valued JR Customers:

During the recent BMFA Nationals, a new JR 7 channel radio system using DMSS was shown by our UK distributor. This system uses a technology that is incompatible with DSM2 in order to meet a market need where DSM2 is not available to JR. Unfortunately, several individuals made statements that JR finds very misleading and require correction.

JR remains committed to future development with DSM technologies and to our customers who currently own JR equipment using the DSM standard. JR will continue to manufacture, sell, and support DSM equipment in all markets currently allowed by agreement.

It is our goal that this communication clears up any questions about JR’s intentions and that JR remains confident in and committed to the future of DSM technology around the world.

We thank you for your continued support.

Kind regards

Mooney Takamura.

Sorry being so last month

ssrobzoom provided a thread that worths a read on the discussion of DSMSS and DSM2 if you haven't done so.

Looks like DSM2 will live but DSMSS will gain good popularity in contries with stricter regulations.

I am just glad that my 12x is modulated not native DSM2. LOL...
