Re: [Discuss-gnuradio] Write bin to SD card
Hi Eric, Thanks very much for your reply. I tried to verify the bin that I programmed in the SD card using -v option. No error message and no success message either. But if I plug in the SD card to the USRP2, I still cannot get any LED on. Do you know what could cause this problem? Thanks!

[Discuss-gnuradio] Using different sizes for the different input ports of one GNU Radio block
Hello, I would like to know if it is possible to use different data types or different vector sizes for the different input ( or output) ports of a GNU Radio block. I explain myself. When the input or output signature of a block is specified, the parameters provided are: minimum number of ports, maximum number of ports and size of the data. This size is applied to all the ports. My question is that if there is any way of specifying different sizes for the different ports. More concretely, in my case I need two input ports where one of them takes a vector of 30 char and a vector of 432 char the other. Since I can only provide one size, I'm specifying 432*sizeof_char, so when I run my flowgraph I get an error message complaining about a size mismatch. Thanks. Best regards.

One place to start is with the digital-bert example application. It is
designed to implement a one-way transmission (using BPSK) between two
USRPs, i.e., it does not implement any packet-oriented overhead and has
the minimal flowgraph necessary to accomplish this.
The TX application sends a bit error rate testing waveform, basically an
LFSR-based pseudorandom bit stream modulated using BPSK and a
root-raised-cosine transmit filter. This is sent continuously.
The receiver application performs RRC receive filtering, carrier
frequency and phase recovery, bit timing recovery, BPSK demodulation,
and measures the bit error rate. It displays, once per second, the
current frequency offset, bit timing error, estimated signal to noise
ratio, and estimated bit error rate. It's easy to see the effects of
multi-path, shadowing, and antenna efficiency this way.
You can modify these applications to implement different
modulation/demodulation (implementing QPSK vs. BPSK is rather
straightforward), and add whatever artificial channel impairments you
wish.
Once you have a feel for how things work at the PHY level, there is the
digital packet radio example application ("tunnel.py"), which not only
implements a highly configurable PHY layer, but has a (really) basic
CSMA MAC and an interface to the Linux IP networking layer, allowing
routing IP between two hosts using USRPs. That may be of interest to
you, but I recommend starting with the simpler continuous transmission
BERT example to get a start on your learning curve.

[Discuss-gnuradio] GNURADIO 64 QAM 200 MHZ
Hi all, I want to configure USRP with Basic TX and Basic RX daughter boards using GNU Radio. I am not sure their capabilities are convenient for VHF 200 MHz and 64 QAM transmission. If they are suitable , which python or C++ programs can I use as examples for writing new program? also I tried to run some examples from gnu radio on USRP.

I believe that what is happening is that on the faster machine, the Tx pipeline in the FPGA is getting disabled before it has a chance to drain. The result of this is that the pipeline is halted with a non-zero constant value getting clocked into the DACs resulting in a carrier for all daughterboards that contain an LO.
