Will deviation solve my problem.

After converting to deviation ,Would I will be able to use my tx with Spektrum DSMX.?

What is the problem you want to solve with DSMX?

And again, as this is a double post, the answer is yes.

I ve the spectrum receiver and want to use it in ikon. So just to know that why devo 10 not work with it. and is deviation solve my problem?

Devo / Devention supports the DEVO (3 channel DSSS) protocol only.
You would need to get a DEVO receiver and connect it to FBL Brain/Ikon.

Or you (better) go the DeviationTX route with the proper firmware version and use Spektrum telemetry / flightlog: www.deviationtx.com/forum/3-feedback-que...0-to-deviation#36173

Asking in two threads in parallel really makes no sense if its almost the same topic. It will not get you more attention.
