Hi
I have been working with Gnuradio and USRP N200 for about a month now and
about all this time I have never succeeded in transmitting digital voice
via USRP. My Proposed approach is like
audio source--->CVSD encoder>OFDM mod-->rational resample to
200k--->multiply with signal

There is a major problem with the way tags are propagated in blocks with
non-integer relative rate. If the ratio is not a power of two, the numerical
accuracy of the floating point will cause the output tags to diverge from the
input tags. Consider the fractional resampler. It accumulates the

Thank you to Nick Foster for pointing that out.

Hi,
The 802.15.4 spec says that the channels should be 2 MHz wide with 5 MHz
inter channel spacing.
Why does gr-ieee 802.15.4 uses a sampling rate of 4MHz instead of 2 MHz ?
Off course it works with commercial devices, but I am curious why 4 MHz and
not 2 MHz.

Sumit
Just wanted to note that space at the Cyberspectrum event on Wednesday is
limited, so you have to RSVP on the Meetup page by Wednesday morning.
Thanks a lot!

Dear all,
We're hosting a special meetup next week in the South Bay! It's the same
week as the DARPA Bay Area SDR Hackfest:

Please get in touch if you would like to present.

Dear All!
I am new to GNU-Radio. I have previously used MATLAB for packet transmission
and detection. Here is the problem, I am facing:
I have inserted zeros between the packets and transmitting the same packet over
and over again. In the packet formation, I have appended two preambles
