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.

I solved it this way instead. I let the function xcvr2450_set_freq in db_xcvr2450 tell the calling function that it was able to set the frequency perfectly i.e. *dc = freq. This seems to solve the problem, though I don't know what the problem was with the solution above.
