Hi, Yes I'm sure, when I remove (or mark //) [d_center_freq = d_tune->calleval(0);] in enter_tune_delay () of bin_statistics.cc, the scanning speed increases rapidly. Is there away to solve this problem and control the USRP directly from the bin_statistics block? Regards, Firas Eric Blosso

[Discuss-gnuradio] Help: make problem with 3.1.1 on 64 bit FC6

Hello, I have a 64 bit machine with FC6. Downloaded the 3.1.1 release tar ball and unpacked it. Did ./configure and everything was fine. Under regular user name I did 'make' and kept getting errors shown below. Never had this problem with previous releases. Anyone has any idea what's wrong? -

[Discuss-gnuradio] Unable to find USRP #0 in kernel 2.6.24-rc4-gd7f0b481 on Fedora 7

I installed kernel of 2.6.24-rc4-gd7f0b481 for Fedora 7 in PS3 following http://www.gnuradio.org/trac/wiki/PS3FC7Install. The linux system runs well. Then I installed GNU radio as told in above URL. Everything went well too. However, I could not get USRP work. I am not sure whether it is because

[Discuss-gnuradio] Controlling USRP From Inside General Gnuradio Block

Hi, If : u = usrp.source_c(0) then if I passed the usrp source instance (u) to a gnuradio block, what is the class (type) that should be used in the c++ code to receive (define) this instance ? I thought at first we can define it as a class of usrp_standard_rx, but I was totally wrong. What

Hi! The intrinsics are more or less C wrapper functions for assembler commands. You can find a detailed description here: http://www.intel.com/products/processor/manuals/index.htm SSE1-3 is supported by modern AMD and Intel processors. There are many possible improvements, but you need to ha

Hi all, I was following the separate discussion on this list about writing various trig functions using vector intrinsics. I googled for it. The top few results I got were for "old" processors when SIMD intrinsics were new. The gcc documentation (my version is 4.1.2) has a list of intrinsics but n

Dear all, I want to know the BasicRx daughterboard can receive FM and AM broadcast? I look the BasicRx daughterboard circuit diagram,but can't find any tune and filter on it. I know the USRP's ADC sample rate is only 64M, it can't sample more than 32M base on Nyquist baseband sa
