Hi John,
Hello list,
Much code has been pushed and new images uploaded.

When you specify the address it works, the other methods do not. This is
likely due to a firewall blocking broadcast packet:

Hello,
I have a strange problem
Hey gang,
I just updated our git master branch with a patch for handling libusb
issues in Windows. Thanks to Michael Dickens for making the patch and
Don Ward for testing it for us. Hopefully, this helps with the Windows
build issues.

I had this same problem with my four USRP2 boards, each with a WBX
daughterboard. The solution was to use the 10 MHz external clock reference
input. I have an HP signal generator which has a precise 10 MHz sine wave
output on the back. I split this signal four ways and input it into each USRP2.
Hi Josh,
Thanks for your hints. It turned out that I had two libuhd.so. One (new
one) in /usr/local/lib and one old one in /usr/local/lib64. GRC always
loaded the old one which caused the crash. After deleting both and doing
a fresh install the problem seems to be solved.
Thanks.

I would like to know a bit more detail regarding the product.
1. It seems like USRP E100 is coming with a TI OMAP board. What is
the memory configuration?
Yes, the Overo board is included in the price. It has 512 MB of RAM and
a 4 GB microSD card.
2. Is everything on one PCB?

You're probably getting bit by the fact that the 3 USRPs have slightly
varying clock offsets. Try a faster bitrate to widen the signal some.

Hello everyone,
I have a problem with my USRPs that I cannot solve. I've got three USRPs and
they are equal and the boards integrated are XCVR2450 Transceivers. I'll
simply call them USRP1, USRP2 and USRP3 to be able to clearly explain my
problem. I want to transmit data from one USRP to another

Hi ,
If any one can tell me in USRP1 ver4.5, how many layer PCB used , i
examined it and it looks like it is double sided PCB,
or it has multiple layers,like 6 layers?
Thanks in advance for confirmation.
