MSP430-CCRFLCD and MSP430-CCRF don't communicate?

I'm trying to establish a RF communication between an MSP430-CCRF and MSP430-CCRFLCD but didn't have much luck.

I'm using the example "smartrf_CC430F5137_868MHz_1k2Baud.h" on both of them but get different frequencies they are transmitting on.

Ill try to attach a fft showing the signals close to each other. It seems that is the reason why they don't communicate. What can I do or what is wrong?

The frequencies of the two are appr. 770Hz apart from each other, CCRF at appr. 867.99966Mhz and the CCRFLCD at 867.99892.

Thanks for any comment
