I'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
The DX8 might be a brand new transmitter and regardless of what happens next year it uses DSM2 which is now old technology, would you go out and buy a five year old mobile phone?,
I really don't understand some of the comments in this topic.
My worry is I spend £300 now on the dx8 then in 12months I'm unable to get any dsm2 rx's. Don't really fancy having to upgrade in 12mths time due to not being able to get any rx's.Steve

My thinking was that if they stopped selling the dsm2 transmitters then they would stop selling receivers for the same system. Sorry if I'm completely wrong but that was just my ill-informed logic.Steve
It's not beyond the realms of possibility that there would be no new models of DSM2 receivers, if the transmitters are phased out.
Your asuming that if the EU restricted DSM/DSM2 power output to 10mW then the system would die in the water. However, the European market is small fry compared to the main Spektrum market, which is the US, then you have Australasia, the Far East (excepting Japan), Africa etc. Having said that, even if the EU laws regulations are changed, we have been told the legacy systems would still be allowed, and there would still be a huge market in Europe for DSM/DSM2 Rxs, even if it means going to the US or elsewhere for the Rxs (but I don't see HH stopping the sale of the Rxs in Europe for quite a while, as long as there's a market for them)You're forgetting the 'rest of the world' market Maybe I was wrong to say 'panicking' in a previous post, when I could well have said 'scaremongering' Mark
I would have thought that the easiest way to make the manufacturers stop providing RX's, would be if everyone panics and tries to sell their DSM2 kit and destroy the market. Who would want to buy the glut of DSM2 equipment anyway if it is doomed?
-3db S:N on DSM2??
I reported some months ago that using the scanner on my Weatronics system, it shows my DX7 always chose channels that were half the available band apart, so for example it would choose channel 1 and 41, or 10 and 50 and so on. It never varied from that, it never chose 2 adjacent channels or even nearby channels.
Hang on a minute, is DSM2 definitely going to be illegal to buy from next year or is it all speculation?
On switch-on the Tx selects one of 40 possible channel sets, and if two did happen to select the same pair (because the second Tx was temporarily masked from the first) then BOTH of its chosen channels would conflict and they would be relying solely on the low duty-cycle for continued communication, which would be rather risky!PDR
I meant to come back on this Harry - are you saying that it *always* selects pairs that are 40 channels apart?
Where does this leave the new JR 11X zero DSM2 tranny
Hi Gordon, yes the 11X DSm2 module fits any normal 5 pin module based Tx.I tested the DSMJ and DSM2 modules on my 9XII.
Macman - and that is exactly the problem.The distributors / manufacturers could prevent wild speculation by an assurance they won't leave DSM/DSM2 users without a future come Oct 2011. A few "what if" scenearios could be run through. Best case scenario would be for JR/Speki to state as soon as possible that they do or do not have an upgrade path if DSM2 is outlawed failure to do so causes the speculation you refer to.
Hmm, fascinating. So FHSS can put all its 100mW power into a 100KHz band whilst others must spread their 100mW over at least 10MHz?
That's over 1 MHz, not 10 MHz!You can improve your S/N ratio either by using more power density, or by using more bandwidth. If you look at the above figures, you will see that DSM uses 10 times the bandwidth, but the power density is 10 times less, so you end up in exactly the same place!
