Ken Tarran Posted February 14, 2008 Share Posted February 14, 2008 Hi All,I need a bit of help to clarify the situation re. my Futaba 6EXA Tx and PPM Mode. Today I have bought a JR RS70 Auto-scan PLL-Synthesizer FM 7ch Rx. I went with the intention of buying a standard 6ch single conversion Futaba Rx into which I would have inserted a standard single conversion Xtal.I was persuaded by the owner of the model shop that the JR Rx, mentioned above, would be a much better and more up to date solution in that it doesn't require a Xtal, it locks on to my Tx automatically and would be compatible with my 6EXA Tx.Having got home and read through the Tx manual and sought info. off the web, I can't find any reference to PPM mode, which is presumably what I will need for this particular Rx to function.If any one can offer me some advice on this one, I would be eternally grateful. My suspicion is that I will be returning to the model shop and doing a swap for the one I had intended to buy in the first place!!Looking forward to your comments.Kind regards,Ken Quote Link to comment Share on other sites More sharing options...
Bruce Richards Posted February 14, 2008 Share Posted February 14, 2008 Ken,The 6EXA is switchable between PPM and PCM. The manual should give you instructions of how to do this. I am not sure about the compatibility between JR synth RX and Futaba Tx but it "should" be fine.Bruce Quote Link to comment Share on other sites More sharing options...
Ken Tarran Posted February 14, 2008 Author Share Posted February 14, 2008 Hi Bruce,I have searched through the manual several times but I can find no mention of being able to switch between PPM and PCM and that's what's bugging me.Ken Quote Link to comment Share on other sites More sharing options...
Bruce Richards Posted February 14, 2008 Share Posted February 14, 2008 OKon my 6EX TX you go into setup buy pressing the two bttons at the same time.then press the select button twiceit should then say PULS on the screen with either PCM or PPM flashing beneath,use the +/- slider to select PPM or PCM.This is how my T6EXAP works. It may be that you have a different model. I did not think that Futaba made a PCM only version of the 6EX,Bruce Quote Link to comment Share on other sites More sharing options...
001 Posted February 14, 2008 Share Posted February 14, 2008 Ken, on my 6 EXA below the screen (on the black plastic frame) it says 'PPM/PCM selectable'. As Bruce says, do not think that Futaba make a PCM only version.Also I have a JR RS 70 receiver and it tunes into the Futaba transmitter.

Ken Tarran Posted February 14, 2008 Author Share Posted February 14, 2008 Bruce and Richard,There is no mention of PPM/PCM selectable at the bottom of the black plastic frame around the LCD screen on mine. All it says INH=inhibit(off) FP=Flaperon V-V-Tail EL-Elevon CL-ClearSounds as though this is a different model of Tx. It clearly states Futaba digital proportional radio control system and T6EXA.Ken Quote Link to comment Share on other sites More sharing options...
001 Posted February 15, 2008 Share Posted February 15, 2008 Ken, you are right, the T6 EXA is FM (PPM) only, although I have never seen one, take the receiver back to the shop and explain. (Print off the table below). The Futaba website shows the differences. Look at http://www.futaba-rc.com/radios/feature-compare.html I think that Futaba must have made this transmitter for a short time then added the PCM system to it and called it 6EXA Super and/or 6EXAP which are very popular models.Might it have been sold in the USA only????

Ken Tarran Posted February 15, 2008 Author Share Posted February 15, 2008 Thanks Richard,I bought this particular Tx from Als Hobbies at the Woodvale Rally 5/6 years ago so I don't believe it came from the USA.Thanks for all your help - at least I know where I stand now. I'll swap it for a standard Futaba Rx with xtal now.Ken Quote Link to comment Share on other sites More sharing options...

Bruce Richards Posted April 18, 2008 Share Posted April 18, 2008 Hi,I think you need to switch the Tx off and back on for the change to take effect. Have you tried this? Quote Link to comment Share on other sites More sharing options...
