[Discuss-gnuradio] Strange side-band when transmitting using WBX on USRP1

Hi All, We're having some problems with transmitting using the WBX board on a USRP1 (not an old one). We have a flow graph with a NULL source going into a NBFM, then through a multiply_const and into the USRP. At low frequencies (100MHz) the signal looks ok, but when we get up passed 500MHz we can
