You *may* be seeing an artifact of the truncation of the ADC samples.

Hi,
How can we get/tap a base band analog signal (I and Q) from the FLEX
900 daughter board. Are there any pins on the board from which the
signal can be taken out directly.
Also where can I find what the different pins on the daughter board can
be used for? Is there a schematic?
-Regards
Radha
Hello,
Thank you. I didn't realize that the boards are not capable of receiving
the waves. Other than that were you able to figure out what rest of the
error messages meant. Because the error messages seem to suggest, that there
is a problem in the code. I could be wrong though. If you were a

Of course I had

I'm still parsing through the rest of the error message, but these
first two lines show that you are trying to receive at 101.9 MHz with

Hello,
I am new to GNU radio. I installed the software successfully on
cygwin, and I tried to run the FM receiver code (both with GUI and without
GUI). I got the following errors.-

Hi,
I would like to save the trasmit data and the receive data using
usrp_rx_cfile.py.
How can I open two port at and save data from two ports at the same time?
If you have better idea and know better code to apply, could you tell me how
to do it?
Thank you.
Sincerely,
James Park
