Hello all,
I am still developping my own board that use the USRP daughter board.
I need to know what is the maximum current consumption of these boards.
Thank you in advance.
If you keep the consumption on the 6V rail to less than 750ma you should
be ok.

In db_base.cc you write that "db_base::tune" should not be located in
