Hi Rahul,
ah! With that information (wrong frequency for daughterboard) it all
makes sense. However, UHD will usually print a warning about not being
able to tune to the frequency.
Now, is it possible that you only copy and pasted a part of your
program's output? Otherwise, we'll have to look into
Hello Rahul,
Thank you for working through the setup with me. The XCVR2450 daughterboard
can only tune as low as 2.4GHz so is unable to receive broadcast FM, which
would use the Wide Band FM Receive block, at 98 MHz. You can try observing
WiFi signals at 2.437 MHz as a pretty reliable test signal.
Block Diagram image is ATTACHED.
But I am actually not confident whether the device is transmitting the
desired input and then receiving it as it is. What i want to tell i have
used GNU Radio Companion for constructing the FM receiver but shows
following error:
Loading: "/home/rahul/fm_rx.grc"
I get a steady stream of zero's on my terminal I believe - if that's what
your asking Martin. I'm not at my radio now. Thanks BTW.

Please answer to the list.
Alright, are you seeing zeros or nada after the FM receiver? See also

Hi again,
I resolved my problem without using the Polyphase Resampler. It was a sample
rate issue which did not match the requirements of the audio card. Anyway,
thank you a lot for your help.

Hi,
I agree that it is a sample rate issue. The USRP sends too many data to the
computer which becomes overrun. As you said, I put a Polyphase Resampler
between the USRP and the WBFM receive blocks (
http://old.nabble.com/file/p31046181/fm_receiver.py fm_receiver.py ). But,

Yes, you must be right, I must have made a mistake when I set up the flow
graph. How do you know the sample rate delivered by the UHD and how is the
Polyphase Resampler implemented into the flow graph ?

Yes, I have already though about that and I tried to match the sample and

These characters being printed means that you have mismatched sample
rates between your USRP device and sound card. Could this be the case?

The fm receiver demo will work when you use a TVRX daughterboard. You
can use a BasicRX daughterboard, but then you would have to use an
analogue filter to prevent aliasing and you would also need to read up
on bandpass sampling to figure out where your frequency of interest
would end up af

Dear Eric,
I would like to try stereo FM receiver with noise reduction technique,
like frequency modulation with feedback on GNU radio with USRP
I read one another technique of noise removal is AM cancellation
do it is possible to implement?
Thanks and regards

Hi,
I have two computers one with Ubuntu 6.01 and the other with 7.1 . The
fm receiver example with gui, "usrp_wfm_rcv.py" works fine with
version 6.01 . However, when I try to run the same example in 7.1 I
cannot control the bars to adjust frequency, volume..etc with mouse
