Brian Dorricott 1 Posted April 18, 2021 Share Posted April 18, 2021 Basic question in title does the TX16S support later JR protocol and if so what is named as ? I know the older protocol was DSM2 but the later was DMSS I think . Asking for a club buddy who's JR TX has seen better days and looking to replace without replacing all his receivers . 1 Quote Link to comment Share on other sites More sharing options...
jrman Posted April 18, 2021 Share Posted April 18, 2021 New JR DMSS Tx's are available from Probuild (if they have them in stock) or Inwoods . Failing that direct from their US warehouse. (JR PROPO / Dee Force Aviation) Quote Link to comment Share on other sites More sharing options...
Piers Bowlan Posted April 18, 2021 Share Posted April 18, 2021 That is a good question Brian, wish I knew the answer. My JR XG11 is still going strong but like your club buddy, I have several JR DMSS receivers and QRX R8DM DMSS receivers too. Should my transmitter stop working and prove to be un repairable for any reason it would be nice to have a replacement Tx that works with all my receivers.

Piers Bowlan Posted April 18, 2021 Share Posted April 18, 2021 Seems the TX16s has an 'improved' JR slot to take the RF module, only trouble is the JR DMSS Tx modules are discontinued and like hens teeth. I did find one on a German website at a price of nearly 200Euro and no guarantee it was in stock either. My XG 11 does not have a removable module but I think some of the earlier ones did?

MattyB Posted April 18, 2021 Share Posted April 18, 2021 The full list of protocols supported by the MPM is here - no JR DMSS that I can see. If there was sufficient demand for it and it was technically possible I suspect they would have added it by now, but I suspect the number of existing JR users who would deem the current MPM hardware of sufficient quality is low. Sorry to say it, but no amount of reassurances from the new owners would convince me to invest in JR at this point - they are just too far behind in features and the distribution is too spotty. Better to plan to move away to something else over time and accept the RXs will have to be sold on or die with that set. Quote Link to comment Share on other sites More sharing options...
Piers Bowlan Posted April 18, 2021 Share Posted April 18, 2021 (edited) Thank you Matty, just reading the marketing blurb seemed to indicate that but your link confirmed it. Quite extraordinary how many protocols and sub protocols there are and it seems some of the ‘new’ manufacturers like FrSky are ever happy to market a new Tx with the latest protocol, not backwards compatible with all your ‘old’ receivers of course (that you may have purchased only last week!) As far as JR are concerned, my XG11 works and I am used to it so why change? When I bought it I was also considering a Hitec Aora 9 but they have gone too, although at least their protocol is supported in the Tx16s. What troubles me about buying any new Tx is how long will it be supported, has it got the latest firmware, if not, can I update it? Also, will compatible receivers continue to be available? Buying a new radio is not just about the cost of the Tx and a handful of receivers but about the time required to learn your way around the software and program your fleet. Time you could be building/ flying models. Edited April 18, 2021 by Piers Bowlan Quote Link to comment Share on other sites More sharing options...
