chipcon cc1070 emissions

Have been designing a paging transmitter for use in europe and ave encountered spurious emissions around 220MHz that are higher or borderline for the etsi 300 220 spec. Has anyone else encountered this problem ? is it something integral within the chip , any ideas anyone.

Do you use a switched power regulator maybe ?..

no, it is battery operated, i know that there is emissions around the 350Mhz mark and had to redesign the output filter to meet the 2nd harmonic requirement, even the reference design they recommend has it , and fails the requirements !
