Further, I found that at the packet size of 1500B, the interval between
two packet transmissions must be less than about 20ms (on an intel
i5-M20 processor); otherwise, the received side couldn't not receive any
packets. This interval decreases as the packet size decreases.

Josh,
Thanks for sharing the information and your changes sound quite reasonable.
However, it seems that your changes have introduced some bugs at the
transmitter side. I updated my system using your new code (following
your instructions in your Feb. 24's email titled "Re: GRC + N210 +

Dear all,
I'm wondering is there any approach can reconfigure the parameters for
top_block while it is running. I've seen a video on Youtube that implemented
the tuning frequency hopping, which is named "A program written for the GNU
Radio that changes the TX frequency of the USRP". This video

I have to do almost the same thing. But me, I have to bypass the data from the
ADC by the mictor connector to a board from Xilinx, a ML401. All the filter
for equalizers or other types should be done in this one and the data go back
in the usrp2 by the mictor connector again.

Hello,
Sorry for answering so late.
@Gabriel Morel
For my Master Thesis I had to implement a kind of test bench for different
versions of a particular block. Nothing really complex, multiplexers,
filters, etc. The point is I must use the USRP2 board.

OK. I'll only test stuff down to 2.5 then.

Hello,
Until last week I was using the Gnu Radio 3.2.2 (which is ready for use in
ubuntu), then I decided to try the latest version (v3.3.1git-147-g5a23954a).
The flowgraph was working perfectly. It's for "in" GRC simulation only. I
know it's very simple and the 38kHz recovery (at the receiver) is

Yes, Josh is right, I just looked to refresh my memory. GRC makes a check
for Python >= 2.5. The rest of GNU Radio doesn't check for a specific
version, just that certai
Hi
I wonder if anyone used Gnu Radio on an Android based netbook? I have a Toshiba
AC100 and wonder if it can run GR?

If you want to filter around 0 to f, then use the complex bandpass
