Not sure on JR/Spektrum compatibility
I've always used JR Rx's with my JR 12X DSM radio.
I need a 9ch Rx and can't find one but there are spektrum ones available. Specifically the AR9030T.
If I'm correct they will be compatible but I'd just like some input.

DSM2 and DSMX are cross compatible, the ONLY caveat is that you cannot mix the components. If it's a DSMX main rx, it MUST have DSMX remotes/satellites. If it's a DSM2 unit, then it MUST have DSM2 remotes/satellites.
DSMX will run a bit faster but the Flight Logs are pretty much useless as there are so many fades with the DSMX channel hopping. The other thing is that the quick connect/power brownout indication is only available in the DSM2 format and the Flight Logs work quite well for those setups.

The JR 12X originally was DSM/DSM2. These original ones could be updated to DSM2/DSMX as are the later ones. The DSMX capable transmitters have the DSMX logo on the screen lens. If the 12X radio is a module version, the screen may or may not have the DSMX logo as only the module had to be sent back for the conversion.

Zeeb says "How does this kind of misinformation get out?"
One reason is that in the US you could get a DMSX version of the JR 12X or get HH to update a DSM2 version to DSMX. However for all of Europe and majority of the rest of the world DSM2 (and DSMJ for Japan) was all you could get. So the post by ColinW is from a European (UK) perspective where the 12X was only ever DSM2 & all the JR DSM receivers were only ever DSM2. Yes I understand a DSMX receiver is backward compatible with DSM2, however, from the European/UK perspective a user wishing to buy only JR receivers DSM2 was the only option and may therefore never have been aware of the DSM2/DSMX backwards compatibility.

Jr incomparable with newer spektrum receivers
Old thread
Update on Jr and Spektrum compatibility
There is a problem with the newer Spektrum Receivers that are dsm2 compatible due to their hardware change, with the ti chip making them incompatible with Jr legacy transmitters.
Older Spektrum Receivers are okay.Jr transmitters will often losing binding.
Newer DSM2 compatible receivers are not compatible with older legacy transmitters do to changes in the hardware. Crashes reported besides loss of bind.
Older receivers worked fine with jr.
8+channel old modules (DM8, DM9, JR 9303) are not compatible with spektrum newer receivers. Even if they appear to work.
All newer spektrum receivers are TI-based and also includes E-flite BNFs.
AR410 and AR620 included
