Convert JR 9303 to spektrum/2.4ghz, options?
I bought my 9303 with synthesized module just before 2.4ghz hit the shelves. Wonderful timing . I've made it last as long as i can but now i'm wishing i had 2.4ghz.

What are my options to switch my 9303 over to 2.4 and is there a way to do this but still be able to switch back and forth to fly all my 72mhz stuff?

Edit: Will need full range for the bigger birds. Also I have several DSMX birds that i fly with a DX4e but i want to fly them with my 9303.

I think this is what you are looking for:

Just unplug it if you want to go back to 72 MHz

9303
Jr makes a drop-in module-I switched mine over 3 yrs. ago and still lovin that radio; if you want to switch back just put your 72mghz module back in!;last year I sent my 9303 to horizon to check it for calibration and they put the latest 2.4 module in it at no charge! Horizon cust. service is the best!
I do a great decending funnel!

That's your best option. Absolutely solid link with great range, inexpensive receivers with sbus support for single line into a flybarless system, and for another $20 or so there's a little screen you can plug in for full telemetry support.

You have an excellent radio for conversion to 2.4 GHz because most manufacturers of 2.4 GHz systems offer JR modules

In no special order the following comes to mind:
Graupner/SJ HoTT
Multiplex
Jeti
Futaba
JR
FRSky
Spektrum
and probably several more...

My own 9303 has been converted to Graupner/SJ HoTT with a Smartbox for telemetry display.

Not all of these are USA FCC approved. Here in the USA we are "protected" from many foreign products.

Unfortunately that's true for the Graupner, Multiplex, and Jeti. The rest are all legal and available here.Nick Crego

Well, then, there is the Spektrum JR module and the OrangeRX module.

I think the module will only operate your DSMX Rx as DSM2 though, and there is no Model Match. The Spektrum module is not upgradeable to DSMX.

just converted my 8103 to 2.4 last summer and am using the FRsky system. The module just plugs into the TX then ya have to set it up which is easy and you can have as many RXs as ya want.Simple to switch over to 72 too just change the module.I don't work for sky rather went with them for good prices/service and communication! the good part is thiers no mystery to setting it upCAUTION!!! politicians may be hazerdous to your well being

" I already have several DSMX birds ... " that you will have to fly in DSM2 mode.

Sorry about that. I presumed that since both Graupner/SJ and JETI have US distributors, their systems would be legal to use.

The transmitters are, but neither distributor has had the modules certified. The Jeti Profibox in the US is the same as elsewhere, but they killed the transmission abilities. Pretty ridiculous.Nick Crego

Thanks for all the suggestions!

For what i want to do it seems i have three options, each with pros and cons...

1. Orange DSMX module
2. Spektrum DSM2 module
3. New/used radio

What to do, what to do...

You might consider picking up a used DX8 as guys are upgrading to the DX9.

What To Do??
If it were me having to choose, I would go with the unit from Horizon without a second thought.. the price includes a 7 channel rx, and this will fly all of your DSMX machines with no hassles or having to buy more rx's and having to change everything over...
Also you can change back to 72 anytime you want..just make certain that your airborne power supplies are up to the task..I like to use 6v packs or 2s lipo and a voltage regulator..I did the same thing to my 10x and it was completly solid..
As far as the DSM2 goes, you will have no problems.. the only time that the DSMX is really recommended is if you are planning to attend large events like IRCHA where there will be over a 1000 pilots..
It is an inexpensive up grade, and you can always keep it as a spare later on when your ready to purchase a new radio..

JMHO!!

Good luck,
Stan
