Hi Josh,
can you explain how and why the frequency translation occurs?
secondly when the same basic tx chip is used on a usrp N210, the
translation occurs at 50Mhz and after. So for USRP N210, the entire range
from 0-250 Mhz is represented by alternating between -50Mhz to +50Mhz. Why
Thanks Tom,
I think I have it worked out now. The sensitivity and gain parameters for
the FM Mod and Quad. Demod blocks are reciprocals of one another. To
control deviation, in these parameters, you can just calculate Modulation
Index. I was doing it the other way around. The bit that made eve
I am trying to get data through a QAM-16 Modulator and just display the data
stream on a Constellation Sink. I have 8khz sampled 8-bit data(char) going into
the QAM Mod block. I have the output of the QAMmod block going directly into
the Const Sink. I am not seeing anything on the Constellation
The XML for filter_rational_resampler_xxx sets the default value of Taps to
None. However, this gives the error Expression "[None]" is invalid for type
complex vector.
Deleting "None" from this box fixes the problem. Is it safe to change my
XML definition to have no default value?
I had the same problem, but realized I was using the GRC .xml definitions
from the previous version (in /usr/local/share/gnuradio/blocks).

Hello all,
I'm using Xubuntu 13.04 and compiled from 3.7git, when I try to run GRC
almost any block that uses constants from the updates name-spaces GRC fails

Dear list,
it's that time of the year: The first CfP for our bi-annual conference,
the Karlsruhe WSR. As before, we hope to have lots of GNU Radio-related
content!
Cheers,
