I have a nice gnuradio app running using USRP, with 3 FFTsinks going at
once, with the 1st FFTsink taking data from the USRP and the 2nd and 3rd
FFTsinks each showing the results of further processing:
1) USRP downconverting to 1 MHz ---> FFT display 1
2) Channel filter LP to 16 kHz ---> FFT displ
Hi,
I also encountered the same errors.
USRPDevice.h:42: error: ‘usrp_standard_rx_sptr’ does not name a type
USRPDevice.h:43: error: ‘usrp_standard_tx_sptr’ does not name a type
Where can I get the "attached patch"???
Thank you,
Jane

Do you have the latest trunk version of GNURadio installed correctly?
Do you have the library libusrp?

Hi all,
I'm studying on GNURadio and USRP with RFX2400. So far I was successfully
able to make new signal blocks (e.g noncoherent FSK demodulator) with using
benchmark_rx.py and benchmark_tx.py and it works fine.
Now I'm interested in inband signaling. I want to know exact time of arrival

I don't recall the details, but I believe that (at least in the US) the
