Seeing that RJ is back...
What are the frequencies being used for the 3 universes?
As others have stated, when RJ sees an Internet cafe somewhere, he drops by to taunt us with all the fun he's having.
And while I feel your pain about the issue of the frequency, I don't feel it enough to do the research for you. Go to the BOM on Mouser, click on the part listing for the transmitter chip and download the data sheet. The frequencies should be in there.
