The Lemon RX DSMP Receiver (this one?
https://lemon-rx.com/index.php?route=product/product&product_id=132) is a DSMX/DSM2 receiver and is compatible with Spektrum DSMX/DSM2 transmitters. The FrSky ACCESS protocol is incompatible. You can get an add-on multi-protocol module to install in the back of the radio that will allow you to use protocols other than ACCESS with that radio.
OK, thanks. Well that sucks. I ordered the x9 because I saw it was Opentx like my Jumper T lite. Since the damn thing is coming from China, sending it back won't work. Been there, tried that.
Oh well, lesson learned. My best option is to get a compatible receiver, I guess.
