You are awesome.

I wonder if this will be necessary for the USRP-N210 since that has a
10MHz TCXO for an "internal" reference.
In another note. I am considering modifying the old USRP classic FPGA
code to get receive timestamps (secs and ticks) for the USRP1 + UHD
support. What is needed for in terms of timestamps with transmit for
OpenBTS? Basically, does it a timestamped send_at() capability?
