[Discuss-gnuradio] DBSRX: Tune the LO from python

Is it possible to set the DBSRX's LO frequency and the FPGA DDC independently? Currently you can set the single quantity (LO - DCC) using the USRP's "tune" member function.

When f = 1.57542GHz, I do not like GNURadio's choice of
LO = 1.5755 GHz
DDC = 80KHz

The board seems to put out a signal at 1.5760 GHz when the LO is tuned to 1.5755 GHz which is not present when the LO is tuned to slightly higher freqs. I would like to tune the LO to the higher freq and use a larger DDC.
