CC2400 technical help

I wonder if anyone has designed in the CC2400 RF transveiver from TI (used to be from ChipCon).

I am experiencing a problem with the transmit function. I can successfully receive though. If I plug in a CC2400EM board, I can transmit, so I know the firmware is right.

I resorted to swapping the inductors off the CC2400EM board onto my board and now I can transmit and receive.

However, I used the same value inductors as specified on the ChipCon reference design.

Does anyone have advice to offer ?
