Hi there,
I am working on a project, where in it requires the OFDM I&Q
samples of my Tx -Rx C program to be transmitted from one USRP2 to another

For initial trails i am trying to transmit a text file which contain set of

Hello All,
I'm trying to recreate Mr. Dayal's thesis about analog tv decoding
using gnuradio.
i have already got the black and white picture after taking 8MHz band
with frequency centered in the middle of the channel.
the problem is, i got about one or two fps with my computer(2.3GHz

Thank you for your reply Eric.
I did print delta and delta.microseconds and guess what I did get this:
Receiver (0) = BABA0002
Requested RX Bitrate: 100k
Probe Level 39
0:00:00.000327 [*This is from printing delta*]
327 [*This is from printing delta.microseconds*]

Hi,
I have an interesting observation to share, and I want to see if anybody
can help me shed some light. When I measure time in python in the following
way:
t1 = datetime.now()
self.start()
t2=datetime.now()
diff = t2.microsecond - t1.microsecond
print "Difference %d", diff
I get very differen

Hi,
That output looks like its from the end of the ./configure script
You should be ok to carry on though as those components are skipped on my
