I've finally assembled the USRP few days ago, after being delayed some months.
The power-on behaviour looks as expected: one led blinks at 3 Hz or so.
The next step is to try out some example, e.g.

There is a condition on line 1008 in usrp_standard.cc code. That condition
limits the LO frequency (see my schematic) to the maximum of 44 MHz, OK?
No, not OK.
