[ MacGregor Industries Modeller Support Centre - Frequently Asked Questions ]

«Some customers have expressed concern over the future availability of DSM2 products from JR. We would like to reassure you that JR DSM2 products will be available for the foreseeable future. Here are our thoughts on the subject, the contents of which have been approved by JR:

There are constant representations being made by other interested parties in the wavebands used for the radio control of models. This is not unique to 2.4 - it used to happen with the FM bands as well (and probably still does!). Anyone well versed in EU policy making would tell you that even if true, such a decision would take many years to come to pass. Even then, such restrictions are seldom applied retrospectively, so DSM2 users can be confident of continuation of supply for a long time to come. And even if DSM2 was restricted for newly imported transmitters in the distant future, additional DSM2 receivers will continue to be available, either as JR or Spektrum products. Our feeling is that Horizon will evolve their DSM2 technology long before any such ban could take effect. Product evolution is going to be a far more decisive factor concerning the future availability of DSM2 products, especially when driven by such a fast moving company as Horizon.

Regarding JR and DSM2, again there is no intention by JR to stop supplying us with DSM2 equipped radios. As far as MacGregor Industries are concerned we will continue to supply JR DSM2 radios for as long as they are available to us.

We will be introducing JR radios with their own DMSS technology as and when they become available. The first DMSS radio that will become available to us is the XG7 which uses Frequency Hopping Spread Spectrum (no k!) and offers telemetry. Since it is a completely new 2.4 system, it is not compatible with DSM2. XG7 is a mid-range radio but we hope to be able to offer more advanced JR DMSS sets sometime in 2011 (however at this time we have no information on the specifications of such a set).

So, to summarise, JR DMSS radios will be introduced alongside JR DSM2 radios. As far as we know, JR will continue to offer both types for us to import to the UK market.»

We do not know what I mean: I'm writing that JR will not suspend the provision of DSM2 but will support a new product in FHSS. Certainly, JR will not abandon those who purchased its products in the past.

Why a new JR 2.4GHz in FHSS? Because, in many countries, as well as in Italy only FHSS link has free use ...

what a headpain!! i don't care about DMSS or fhss or others. i like my bnf in dsm2, i have a lot of receivers in dsm2, i like my spektrum radio and i'm happy with them and never give my troubles..spektrum is a good radio!!!

In effetti, molto spesso, le scelte dei Costruttori sono più che altro scelte di tipo commerciale e/o di marketing (seguono un po' quella che è la 'moda' del momento, magari sulla scia del successo del prodotto di un'eventuale concorrenza ).

Dal punto di vista tecnico, il metodo FHSS (ossia, il Frequency Hopping) mi piace molto; tuttavia mi sembra che il DSM2 di Spektrum sia più adatto a micro modelli (per volo indoor), che a modelli sperimentali di una certa complessità e costo, dove è importantissima l'affidabilità del SW e del collegamento radio (sia esso bidirezionale o meno).

Non oso pensare a come si possa sentire un qualunque aeromodellista che vede sfracellarsi al suolo più di 2000 Euro di un suo 'oggetto volante', per colpa di un bug nel SW o di una o più perdite casuali del collegamento radio


Ciao!

One thing that you might not know is that Spektrum’s DSM/DSM2 technology satisfies each of the requirements of FHSS modulation as specified in EN 300-328:

1) [ http://support.horizonhobby.de/getat...9yeSBGQVEucGRm ]

«Spektrum’s DSM technology satisfies each of the requirements of FHSS modulation as specified in EN 300-328 v.1.7.1. As the closing sentence of that clause states, “Systems that meet the above constraints shall be tested according to the requirements for FHSS modulation.” Therefore, DSM is subject to the maximum power level of 100mW as detailed in clause 4.3.1.2, and not subject to the limit of non-FHSS systems of 10mW as specified in section 4.3.2.2. Conformity tests as well as on-going production tests confirm that EU versions of DSM products meet the 100mW requirement. DSM then combines the coding advantages of traditional DSSS systems within the modulation requirements for FHSS to yield a secure, robust, full range radio control system.»

Una cosa che forse non sapete è che la tecnologia DSM/DSM2 Spektrum soddisfa tutte le esigenze di modulazione FHSS come specificato nella EN 300-328:

1) [http://support.horizonhobby.de/getat...9yeSBGQVEucGRm]

La tecnologia DSM «Spektrum soddisfa tutte le esigenze di modulazione FHSS come specificato nella norma EN 300-328 v.1.7.1. Come la frase di chiusura di tale clausola, "Sistemi che soddisfano i vincoli di cui sopra devono essere provati in base ai requisiti per la modulazione FHSS." Pertanto, DSM è soggetto al livello di potenza massima di 100mW, come specificato nel punto 4.3.1.2, e non soggetti al limite dei sistemi non FHSS di 10mW come specificato nella sezione 4.3.2.2. test di conformità, nonché in corso prove di produzione confermare che le versioni UE di prodotti DSM soddisfare il requisito 100mW. DSM combina quindi i vantaggi dei tradizionali sistemi di codifica DSSS tra i requisiti per la modulazione FHSS per produrre un sicuro, robusto, completo di impianto radio gamma di controllo ».

I know, I Know but it is not same thing in Italy, as in other countries too ... radiocomando
I understand you'll be a fan or employee of the spektrum but I remember you that new JR choice is FHSS as Futaba, Weatronic, Multiplex, Hitec, Sanwa, Jeti, Frsky ... and tomorrow JR too ...

Have good flights!

ma questa discussione non era sulla dx8?
e in italiano?

io intanto aspetto l'aggiornamento per la dx8 con ......................x
forse è vero che la dx8 è stata un'ottima scelta

Quindi la nuova tecnologia sulla DX8 sarà attivabile con un aggiornamento?
Speriamo non sia a pagamento, visto che per aggiornare le altre Spektrum e JR ci vogliono un po' di eurozzi
