Quote from: Lplus on August 22, 2010, 21:36:59 pmAh, so Horizon could update the Spektrum equipment to DSMJ but JR could only sell new DSMJ equipment?BTW the info on the DSM2 picking 2 close frequencies is here http://www.rcmodelreviews.com/dsm2flaw.shtml
QuoteI think the only thing that would cause such problems would be deliberate malicious action and if someone wants to be malicious they could equally splatter right across the part of the 2.4 Gig band modellers use then it won't much matter what protocol type you radio uses.
Quote from: CHEL on August 24, 2010, 09:07:06 amWhat, do you mean it would even interfere with Mmmultiplex, gulp, what is this world coming too. My goodness, they told me it was bomb proof.Phil.
QuoteSo if MacG went to DSMJ the jap sets would become UK legal?
Quote from: mac_man on August 24, 2010, 22:02:01 pmNo, as they have not been CE tested.There is something in the wind and I am waiting for permission to release the info. Hopefully I will be allowed to say more next week.
Quote from: mac_man on August 27, 2010, 11:26:32 amOkay, Have been given permission to release....JR will be bringing out their own 2.4 GHz systems on new future systems. Their new 7 channel system is undergoing full CE testing at the moment and for aircraft use it will be full FHSS.It is hoped to be in production in October, they will be dropping the DSMJ system and from what I can gather, no longer manufacturing DSM2 FOR NEW SYSTEMS.They will still be supporting the DSM2 for some period of time.Their entry level set is called the XG7 and supports telemetry. The receiver is fitted with 2 long antennas ( similar to Futaba/Hitec) and comes with a telemetry sender. Currently it is for Rx battery voltage but you will be able to add additional probes to it.For those of you heading to the NATS this weekend, it will be there.Transmitter styling is that of the 2720/DX7.As it is a completely new system and not based on Spektrums hardware, there is no compatibility or upgrade path with DSM2.
Quote from: Steve J on August 25, 2010, 14:07:25 pmThis topic has cost me £50 . After reading the report that said that DSM2 can pick adjacent frequencies, I went and bought a USB 2.4GHz scanner. I am happy to report that my DSX9 picks frequencies 40MHz apart. I'll post some scans in separate topic.Steve
Quote from: satinet on August 27, 2010, 12:18:23 pmit does say they will still be supporting DSM2 for a while though........
Quote from: satinet on August 27, 2010, 12:58:28 pmI don't know anything about the way JR works. I am a, yes, multiplex user, but really I can't see in the long term that one of the two biggest rc electronic manufacturers in the world (?) is going to sell radios for ever that it doesn't wholly control in terms of the design and development of the RF part of it.I might be way off the mark, but it seems an inevitability.
Quote from: Alan H on August 27, 2010, 12:29:45 pmI was thinking of buying a USB 2.4GHz scanner to replace my home constructed parallel port scanner (no parallel port on my new PC). I wondered which one you bought as the Wi-Spy is around £100.

Quote from: bugsb on August 27, 2010, 13:02:41 pmi can see allot of sets going on the bmfa and ebay very soon Ron
Quote from: Steve J on August 22, 2010, 11:15:31 amAn output from a spectrum analyser was posted by Mpx which showed the two selected frequency bands 40Mhz apart.Steve
Quote from: Barrye on August 27, 2010, 18:40:49 pmThis explains why all of the 11x's came in with DSM2 modules, not integrated. No doubt in a few months there will be a new module and a software upgrade for telemetry.
Quote from: FlyinBrian on August 27, 2010, 12:16:36 pmWell a guess some news is better than none. From what you say there will be no upgrade path from DSM2 to JR FHSS. JR are abandoning several thousand modellers who have bought JR DSM2 sets, even those bought recently!If that is the case then thanks very much JR, it will be a long time before I buy anything with a JR label
Quote from: FlyinBrian on August 29, 2010, 06:40:52 amA clubmate just bought a complete Turnigy system Tx & 2 rxs for c£80 delivered. I flew it in an electric glider and it seemed fine, he flew the other rx in a Boomerang trainer and this also was fine.The FRSky stuff seems very good and good value, I think I may be doing some experimenting soon.Can anyone say (MacMan?) if the DSX9 has a convenient PPM signal that can be picked up to drive the FRSky module?Yes I am aware that some FRSky Tx modules have died but these all seem to happen at switch on with the model safely on the ground.In the longer term I can see myself returning to the fold of MPX and to JR
Quote from: bullfrog_sc on August 29, 2010, 13:01:25 pmI'm in the process of having to replace my Futaba FF9 as its been playing up lately. With all this going on, i'm now reluctant to upgrade to my chosen tx, the new DX8. What would most people do with the DSM2 saga, bite the bullet and get one or opt for something else.Steve
