Hi Charles,

You have to tell it to use them.

Take a look in <usrp2/usrp2.h>:

  config_mimo(MC_WE_LOCK_TO_SMA)
  sync_to_pps()

There are python bindings for these.
(Oops, looks like we're missing the python binding for config_mimo...)
Are you using this from Python?  If so, I'll fix this later on today.

Eric
