hi everyone. i was working with the USRP1. I'm testing a MOD/DEMOD DBPSK. I
have only one USRP, so, i connected TX_A( from daughterboard LFTX-LF) to
RX_A ( from daughterborad LFRX-LF) with a coaxil. All system works well
without URSP but when i taste with the USRP i get so much noise and the
Thanks, Marcus. You're absolutely right. I didn't read carefully enough.

card family--they don't have any gain--they're just ADC/DAC buffers, so
it's generally safe to loop them directly.

Hi Lucas,
You say you connected TXA to RXA directly
Hi Lucas,
You say you connected TXA to RXA directly via a cox cable? Did you put an
attenuator inline? I am afraid you may have damaged your RX side by
transmitting directly into it without protection. Most USRPs can be
damaged with input power greater than -10 dBm. Disconnect that cable
Hello list,
Please refer to the attached flowgraph. In it I use two methods to
generate 3 tones of equal amplitude.
The first method simply uses 3 signal sources to generate the
required tones directly and sums them together. The second method
multiplies two signal sources to generate the
Hi Liwei,
they *should* be coherent, because GNU Radio has no relationship to
real wall-clock time and just outputs mathematically calculated
numbers, just like matlab does.
Depending on the number of samples we talk about when you say over
seconds, this might simply be a matter of numerical

Hi Folks,
I am attempting to get some FEC working with my GRC OFDM Transmitter
and Receiver, which I created by modifying the example versions. You

I tried to build everything out as a GRC graph. I don’t think it has anything
to do with the wav file sink. I recorded the raw signal and everything is
working fine until it gets to the vocoder block, DSD. It handles decoding fine
when there is only one instance, but when there are multiple
