Thank you Don. I dont think I am capable of solving the problems faced. Too

Following up on my previous email, thinking about this some more:

That's very interesting... just this morning we were playing with

If we turn off RX pause (ethtool -A eth0 rx off), does the USRP2 stop
sending pause frames?
We are running two USRP2s connected with a MIM

No, we didn't design the LP0926. Going down to 50 MHz would make for a
huge antenna.

Really, if you're going to be using the full range of the WBX, you
should probably use something

Hi Matt,

You should make a hier2 block that has a gr.message_source inside of it.
You can put data you read from the serial port into a message queue.
(internally) The message sink will pop items off of the queue and into a
gnuradio stream.
Take a look in grc/grc_gnuradio/blks2/* for example. Several o

I'd also tried a similar approach. But the data acceptable on Scope sink

Thanks for the tip Alex. The only library I had installed with -dev was
the
libqwt5-qt4-dev you suggested. I removed even the runtime library for qt3.
As expected, that didn't solve my problem, but I noticed that it was

Sorry, cannot wait !!.
Ettus website says it is full duplex. Gnuradio code says it is half-duplex.
Which one is right?
