[Discuss-gnuradio] Setting dxc_freq to zero on xcvr2450.

[Per Zetterberg]

Dear List,

I am trying to set the dxc_freq to zero on xcvr2450. What I did was 
changing the implementation of db_tune (I am still running the VRT 
branch, excuse me for this, I will switch ASAP) so that the call of 
db_set_duc_freq and  db_set_ddc_freq uses zero as it's first argument 
(for the dxc frequency).

In the transmitter it seems to work OK but the receiver hangs.
