Succeed!
The system variable definations for previous installed v2.8 affected my new installation.
I use to install all the components into a stand alone directory, eg.
~/gr. And some definations like $GR, $PKG_CONFIG_PATH are according to
that. So when I install the new verison without "--prefix=$

If your current path loss calculator doesn't accomodate for terrain,
you might give SPLAT! (http://www.qsl.net/k

Hello Marcus!
Could you make a recording of this signal?
AFAIK radars usually use Chirp signals, they correlate good.

I can make a recording of the 20Khz or so of post-detector signal.

My lab will hopefully be getting a Mac Pro pretty soon, so I can
debug this in person when that happens (if it's still necessary);
hopefully the fix will commute to the MacBook as well.
I can tell you up front from the output you provided that it's a
LIBUSB issue, since "usb_claim_interface
Hi Ryan,
No, I didn't find anything more. It is a very strange problem because
I couldn't reproduce it on my intel mac mini. There, the USRP works
just fine. Also, I installed Linux on my macbook and there, the USRP
works without any problems.

There are double pulses that I'm seeing, with variable timing between
the main pulse
and the sub-pulse. The other 1350Mhz radar is much further away from
me, but
perhaps the "sub pulses"
