Dear all,
I conducted a simple experiment (using GRC) to test the TPB scheduler's
performance, and following a search here, I cannot find any definitive
information that would explain the observed behaviour. I kindly request your
thoughts on the matter:

Many thanks.

I've been using GR on Linux for some time, and thought I'd compare its

We are experimenting with two USRP1's (each with RFX2400) and noticed
some strange behavior. We use the

it once and the number of corrupted/lost packets is rather small, say
0-2%. Without modifying any default values of par

Thank you all for your help.
Since I am new in Linux and GNU software Radio, I wanted to start from
known good configuration people use, so I wiped out FC14 and installed
FC13. After the fresh installation, it started working (I was able to hear
tones from my PC's speaker when I ran noise, dial
Yep, it was just enabled, and I am now as well.

Hi, Thilo,
Thanks a lot for your help!
We also need to modify the gr_ofdm_frame_sink.i and then it works.
Good luck!

Tom,
The blog format is rather interesting. One question - would you be
able to setup an RSS feed so that those of us that are into using feed

Hi Eric
What is the difference between WBX_NG and WBX_LO.
If we see in the daughter boards ID's, there are two ID's available for WBX.
Which is the right EEPROM ID for WBX daughter board ?.

Do you have an oscilloscope? Is the transmitter actually transmitting?

Hi all,
I'm a newbie in gnu software radio (and in python, and in linux) and got

I am trying to setup GNU software radio on a machine (HP workstation
xw8600 with dual intel Xeon processor).
I installed Fedora Core 14 and installed all needed dependencies
