A couple of items:
The DX6 does not have the safety mechanism that makes it not work with the wrong model memory selected. Crashed my mini Funtana that way!!

Also, the recievers that came with the DX6 had dual receivers built into the same package. It just had two antennas coming out at right angles to each other.

Finally, Spektrum just announced (last week) their module for JR and Futaba radios. Now you can swap out the crystal pack and antenna and your regular TX is now a DSS system. More info at: [link=http://www.spektrumrc.com/]Spektrum RC[/link].
